Description

  The present invention relates to a method of manufacturing a metal plate incorporating a wood plate.

  Metal plates with built-in wood boards are used as shelf boards. As shown in FIG. 1, most of the metal plates with built-in wood plates used are such that side plates 2 are erected on three sides of a rectangular metal surface plate 1, and the ends of the side plates 2 are directed to the inside of the surface plate 1. Bending toward the locking piece 3, opening the remaining one side of the surface plate 1 to make a cover plate with one open side, and inserting the wooden plate 4 into the cover plate from the open side, The surface of the plate 4 is made to adhere to the inner surface of the covering plate.

  The metal plate with a built-in wood plate shown in FIG. 1 is used as a shelf plate with the surface plate 1 facing upward. Since this metal plate exposes the wooden plate 4 on one side surface 5, it does not look good. For this reason, when this metal plate is used, the exposed side surface 5 of the wooden plate is directed in a direction not visible to the human eye, for example, facing the wall. In particular, when it is not desired to show the exposed surface of the wooden board, two metal plates are used so that the exposed surfaces of the wooden board face each other. However, it is inconvenient to divide and use two metal plates.

  As shown in FIG. 1, the one-side open type cover plate has been used because it is not easy to work to close the exposed surface of the wooden plate with a close metal plate. In order to prevent the wood board 4 from being exposed on the side surface 5, as shown in FIG. 2, four side plates 2 are attached to the four sides of the rectangular surface plate 1, and three of the four side plates are first introduced. Anyone thinks that it is only necessary to stand the side plate, insert the wooden plate after the side plate 6 not standing upright, and then stand the side plate 6 upright. However, it is not easy to erect the side plate 6 after inserting the wooden board 4 and to bring it into close contact with the wooden board.

  The reason why it is not easy to erect the side plate 6 is as follows. In general, in order to bend and stand a metal plate, it is necessary to install a fixed die that regulates the standing state and a movable die that stands the metal plate. However, when the wooden board is inserted, there is no space for installing the fixed mold, so the fixed mold cannot be installed. This is because the wood board cannot serve as a fixed mold.

  The open side plate is pre-treated on the one side open type cover plate shown in FIG. 2, and after inserting the wood plate, the open side plate can be easily erected, and the four side surfaces of the wood plate There is also known a method of manufacturing a metal plate with a built-in wood plate in which all of the above is covered with a metal plate. This is described in JP-A-2015-107580. In the method, as shown in FIG. 3, the folds of the side plate 6 on the open side, that is, the boundary line 7 between the side plate 6 and the surface plate 1 is irradiated with laser light, and the cuts 8 are provided intermittently. Is the method.

  However, the metal plate with a built-in wood plate produced by this method appears as a pointed tip of the cut 8 when the side plate 6 of the cover plate is erected. Therefore, if the hand touches the cut 8, the hand may be damaged. To prevent this, the pointed tip may be scraped off, but doing so is cumbersome and not easy to implement.

  Therefore, it is a method that industrially easily produces a metal plate with a built-in wooden board that has a good appearance by covering all the surfaces and four sides of the square wooden board with metal, and that all the corners are smooth and there is no risk of injury to the hands. Appearance was desired.

  The present invention answers the above-mentioned demand, and is a metal plate with a built-in wooden plate in which the surface and four side surfaces of a rectangular wooden plate are all covered with a metal plate, and the built-in wooden plate has a smooth corner. The present invention has been made in an attempt to provide a method for easily manufacturing such a metal plate industrially.

  As shown in FIG. 4, the method according to the present invention uses, as a material, a wooden plate with a built-in wooden plate A which is formed by covering a wooden plate with one side surface 5 of the wooden plate 4 exposed. The gist is to make a metal plate with a built-in wood plate, in which the side surface 5 is covered with the lid B and one surface and the four side surfaces of the wood plate are all covered with the metal plate.

  To make the metal plate A with a built-in wood plate, first, as shown in FIG. 5, a uniform width corresponding to the thickness of the wood plate is formed on the three sides of the square surface plate 1 having a size covering the surface of the wood plate. It is necessary to punch the metal plate into a shape in which the side plate 2 is held and the engagement piece 3 is continuously provided at the tip of the side plate 2. Next, the three side plates 2 are erected so that the locking pieces 3 come inward, and first, a metal cover plate that is open on one side is made. After that, a wooden board is inserted into the covering board from the open side to obtain a wooden board built-in metal plate.

  In order to make the lid B, first, as shown in FIG. 6, a rectangular side plate 11 having a shape and a size just covering the side surface 5 of the wooden board is defined, and a locking piece is formed on one long side of the side plate 11. 12, the insertion piece 13 is connected to the other long side, and the metal plate is punched into a shape in which the insertion pieces 14 and 15 are connected to the short side. In this case, it goes without saying that the shape of the locking piece 12 should be a shape that just fills the missing portion of the locking piece 3 in the metal cover plate. Next, the locking piece 12 and the insertion pieces 13, 14, and 15 are bent at a substantially right angle in the same direction with respect to the side plate 11 to form a shape as shown in FIG.

  The lid thus made is made to face the metal plate built-in metal plate, and the locking piece 12 of the lid B is placed toward the wood plate exposed surface 5 of the wood plate built-in metal plate A as shown in FIG. Next, the lid B is advanced in the direction of the arrow, and the insert pieces 14 and 15 are inserted between the side plate 2 and the wood board 4, and the insert piece 13 is inserted between the surface board 1 and the wood board 4, The lid B is pressed against the metal plate A.

Then, the locking pieces 12 of the lid B are abutted with the locking pieces 3 of the metal plate 4 so that the locking pieces are formed in series on the four sides of the wooden board 4. Further, the wood plate exposed surface 5 of the metal plate A is completely covered by the side plate 11 of the lid B. In this way, a metal plate with a built-in wood plate as shown in FIG. 8 is obtained.
This is the method for producing a metal plate with a built-in wood plate according to the present invention.

  As described above, the present invention uses a metal plate having a thickness of 0.4 to 1.6 mm, a side plate having a uniform width on three sides of a rectangular surface plate, and a locking piece connected to the end of each side plate. A metal plate is punched into the provided shape, and the three side plates are erected so that the locking piece comes inward to make a metal cover plate that is open on one side, and a rectangular side plate that covers the open side of the cover plate separately, A metal plate is punched into a shape in which a locking piece connected to one long side of the side plate and an insertion piece connected to the remaining three sides of the rectangular side plate are integrated, and both the locking piece and the insertion piece are the same. Make a metal lid by standing on the side, insert a wooden board from one side where the cover plate is opened, then face the lid on the opened one side, and cover the cover with the inserted piece of the cover A method for producing a metal plate with a built-in wood board, wherein the lid is fixed to the metal plate with a built-in wood board by being inserted between a face plate or a side plate and the wood board It is intended to provide.

  In this invention, a side plate having a uniform width is formed on three sides of a rectangular surface plate, and a metal plate is punched into a shape in which a locking piece is attached to the tip of the side plate, and the three side plates are arranged so that the locking piece comes inward. A metal cover plate which is erected and opened on one side is used, and such a metal cover plate is known. In the present invention, since the cover plate having such a structure is used, it is easy to insert the wood plate into the cover plate, and the wood plate is locked by the locking piece only by being inserted. It is easy to make a metal plate.

  Further, in the present invention, a metal lid is made separately from the covering plate, the lid is a rectangular side plate covering the open side surface of the covering plate, a locking piece continuously provided on one long side of the side plate, and a rectangular shape. The metal plate is punched into a shape that integrates the insertion pieces connected to the remaining three sides of the side plate, and both the locking piece and the insertion piece stand on the same side. When contacting the open side of the metal plate, the three side inserts are inserted between the surface plate of the metal plate or between the side plate and the wood plate, respectively, so that the side plate of the lid is exposed to the wood plate of the metal plate with the built-in wood plate. Can be reliably attached to.

  Further, in the present invention, an insertion piece is attached to the lid, and since this insertion piece comes into contact with the inner surface of the side plate and the front plate of the wrapping, the adhesive is attached to the outer surface of the insertion piece. The lid can be easily fixed on the cover plate.

Furthermore, the metal plate with a built-in wood plate made according to the present invention has a built-in wood plate in close contact with the metal cover plate. However, when the metal plate is struck or collided with another object, the wood plate suppresses the vibration of the metal plate, and thus has an effect of suppressing the sound of the cover plate. Therefore, it is valuable as a metal silencer. Therefore, the metal plate with a built-in wood plate can be used not only as a shelf plate but also as a door of a metal storage, and can be expected to be used widely.

The present invention is directed to a method of making a metal plate with a built-in wood board, and after the metal cover plate and the metal lid are separately made and the cover plate has built-in the wood board, the cover plate The main point is to attach a lid to the.
As the metal plate, a steel plate, particularly a stainless steel plate, an aluminum plate, or the like can be used. The metal plate has a thickness in the range of 0.4 to 1.6 mm. Among them, it is preferable to use those having a thickness of 0.6 to 1.2 mm, particularly 0.8 to 1.0 mm.

  As a wooden board, the thing whose length is 300-1200 mm, width is 300-2400 mm, and thickness is 15-40 mm is used. Further, as the wood board, a dry natural wood board can be used, but it is preferable to use a processed wood board. As the processed wood board, for example, a particle board in which a piece of wood is hardened in a plate shape with a synthetic resin, or a veneer board can be used. In particular, it is preferable to use a laminated plate made by adhering veneer plates to both sides of a particle board. Further, the wood board is preferably a single body as a whole, but may be divided into two or more pieces.

  Moreover, the wooden board may be made using a material other than wood in part. For example, as shown in FIG. 9, a rectangular frame composed of a long side A and a short side B is made using a long wooden core material having a rectangular cross section, and a reinforcing piece C is placed between the long sides A facing each other. Then, a reinforcing frame is formed, and a space inside the reinforcing frame is filled with a honeycomb board or plastic foam D made of plastic or reinforced paper, and this is used as a substrate. A veneer plate E is attached to both sides of the substrate and used as a wood board. This wood board has the advantage of being lightweight.

  In the present invention, the cover plate is made of a metal plate. In order to make a cover plate, it is necessary to punch a metal plate into the shape shown in FIG. The shape is such that the side plate 2 having a uniform width corresponding to the thickness of the wooden board is connected to the three sides of the square surface plate 1, and the locking piece 3 having an appropriate width is connected to the tip of the side plate 2. It is. Although the magnitude | size of the surface board 1 changes with the magnitude | sizes of a wooden board, the surface board 1 is 1200 mm long and 2400 mm wide at the maximum. The width of the locking piece 3 is about 42 mm at the maximum.

The metal plate thus punched is bent, and first, each locking piece 3 is erected on the same side with respect to the side plate 2. Next, each side plate 2 is raised to the same side with respect to the surface plate 1 so that each locking piece 3 comes inward. Then, each locking piece 3 extends in parallel with the surface plate 1, and a side-opened box-like body in which each side plate 2 stands on three sides of the surface plate 1 is formed. This box-shaped body is a wooden board covering plate.
The covering plate is a metal plate with a built-in wooden plate by inserting a wooden plate from the opened one side.

  In this invention, a metal lid is made separately from the cover plate using a metal plate having the same thickness as the metal from which the cover plate was made. For this purpose, it is necessary to punch the metal plate into a shape as shown in FIG. The shape is basically a rectangular side plate 11 having a shape and a size just covering the wood plate exposed surface 5 of the metal plate A with built-in wood plate in FIG. 4, and is locked over the entire length of one long side of the side plate 11. In a shape in which the pieces 12 are continuously provided, the insertion pieces 13 are provided continuously on the entire length or part of the other three sides, and the insertion pieces 14 and 15 are provided on the short side of the side plate 11 over the entire length or part thereof. is there.

The locking piece 12 has the same width as the locking piece 3 provided on the cover plate, and both ends of the locking piece 12 are formed so as to be just abutted with the locking piece 3. In FIG. 6, both ends of the locking piece 12 are inclined at an angle of 45 degrees.
The metal plate thus punched has the locking piece 12 and the insertion pieces 13, 14 and 15 standing upright with respect to the side plate 11 to form a groove as shown in FIG. The groove structure made in this way is the lid B.

  In the present invention, an adhesive is provided on the outer surface of the insertion piece 13 of the lid B thus produced so that the lid B faces the metal plate A with a built-in wood plate, and as shown in FIG. The protrusion 12 of the piece 12 is placed toward the wood plate exposed surface 5 of the metal plate A. Next, the lid B is advanced toward the metal plate A, the insertion piece 13 of the lid B is inserted between the surface plate 1 and the wood plate 4, and the insertion pieces 14 and 15 are inserted into the side plate 2 of the metal plate A and the wood. Insert between board 4. When the lid B is further pushed forward, the side plate 11 of the lid B completely covers the exposed surface 5 of the metal plate A.

Then, the locking piece 12 of the lid B comes into contact with the locking piece 3 of the metal plate A. Therefore, when the lid locking piece 12 is pressed against the wood plate 4, the lid insertion piece 13 is brought into close contact with the inner surface of the surface plate 1 of the metal plate, and the insertion piece 13 is adhered to the inside of the surface plate 1 by an adhesive. Bonded to the side. Thus, a metal plate with a built-in wood plate as shown in FIG. 8 is completed.
The locking pieces 3 and 12 are preferably fixed to a wooden board with screws.

As the adhesive attached to the insertion piece 13 of the lid B, an adhesive generally used for bonding metal and wood can be used, but a double-sided pressure-sensitive adhesive tape is preferable. That is, when a double-sided pressure-sensitive adhesive tape is applied to the outer side of the insertion piece 13 of the lid B, it is not necessary to wait for the adhesive to dry, and it is convenient because the bonding can be completed simply by pressing.
Adhesion of the lid B to the metal plate A is performed by attaching an adhesive to the inner surface of the locking piece 12 and / or the upper surface of the wooden board 4 and / or the outer surfaces of the insertion pieces 14 and 15 of the lid B. You can also.

In the metal plate with a built-in wood plate according to the present invention, the back surface of the wood plate is in contact with the same metal plate as the cradle plate or a synthetic resin plate such as polyethylene to cover the entire surface of the wood plate, and wood chips coming out of the wood plate, etc. It is preferable to prevent the fall of the.
Next, an example of implementation will be described.

  As the wood board, a board having a length of 900 mm, a width of 1800 mm and a thickness of 20 mm was used. As shown in FIG. 9, the board is a laminated material, and veneer boards are pasted on both sides, but the intermediate layer has a rectangular frame of 900 mm in length and 1800 mm in width using wooden squares. I made a wooden slab between the long sides facing each other, and used a space filled with a honeycomb board made of reinforced paper.

  More specifically, a wooden square is 15 mm in thickness and 50 mm in width to make a long side material with a length of 1800 mm and a short side material with a length of 800 mm, and using this, the length is 900 mm. A rectangular frame with a side of 1800 mm was made. Two first reinforcing squares are placed with 125mm space to the right and left from each short side of 900mm of this frame, and two first reinforcing squares are placed with 300mm space to the right or left from the first reinforcing square. A reinforcing frame was made with two reinforcing squares and a third reinforcing square with a space of 300 mm from the second reinforcing square. Each space of the frame was filled with a honeycomb board made of reinforced paper to form an intermediate layer having a thickness of 15 mm, a length of 900 mm, and a width of 1800 mm.

A veneer board having a thickness of 2.5 mm was pasted on both surfaces of the intermediate layer to produce a wood board having a thickness of 20 mm.
A stainless steel plate having a thickness of 0.8 mm was used as the metal plate. As shown in FIG. 5, this stainless steel plate is connected to three sides of a rectangular surface plate 1 having a length of 900 mm and a width of 1800 mm in accordance with the shape of the above-mentioned wood board, and a side plate 2 having a width of 23 mm is continuously provided. A stainless steel plate was punched into a shape in which a locking piece 3 having a width of 22 mm was continuously provided at the tip of the side plate 2.

The punched stainless steel plate first raises each locking piece 3 to the side plate 2 with respect to the side plate 2, and then raises each side plate 2 from the surface plate 1 so that the locking piece 3 comes inside. A box-shaped molded body with one side opened was made. This molded body is a metal cover plate.
Thereafter, the above-mentioned wooden board was inserted from the open side of this metal cover board to make a wooden board built-in metal board.

  Separately, a 0.8 mm thick stainless steel plate was punched into the shape shown in FIG. The shape is such that the side plate 11 located in the center is a rectangle having a length of 23 mm and a width of 900 mm, and is just large enough to block the open side surface of the metal cover plate. A locking piece 12 having a width of 22 mm is continuously provided on one of the long sides of the side plate 11, and an insertion piece 13 having a width of 800 mm and a width of 20 mm is continuously provided on the other long side opposite thereto. It was. Further, insertion pieces 14 and 15 each having a length of 20 mm and a width of 20 mm were continuously provided on the short side of the side plate 11.

The stainless steel plate punched out in the shape of FIG. 6 was formed into a groove as shown in FIG. 7 by raising the locking piece 12 and the insertion pieces 13, 14 and 15 on the same side with respect to the side plate 11. This groove structure is a metal lid.
In the metal lid, a double-sided pressure-sensitive adhesive tape was applied to the entire outer surface of the insertion piece 13 over the entire surface.

  Thereafter, as shown in FIG. 4, the locking piece 12 of the lid B was placed toward the wood board exposed surface 5 of the above-described wood board built-in metal plate. Next, the lid B is advanced in the direction of the arrow, and the insertion piece 13 of the lid is inserted between the surface plate 1 and the wood plate 4 of the metal plate A with the built-in wood plate, and at the same time, the insertion pieces 14 and 15 of the lid B are respectively inserted into the metal plate. It inserted between the side plate 2 of A and the wooden board 4, and the lid | cover B was pressed on the metal plate A further.

  Then, the locking piece 12 of the lid B was abutted with the locking piece 3 of the metal plate A, and the exposed surface 5 of the wooden board 4 was covered with the side plate 11 of the lid B. In this state, when the locking piece 12 was pressed toward the wood plate 4, the insertion piece 13 of the lid B was firmly bonded to the surface plate 1 of the metal plate A by the double-sided adhesive tape. Thus, the lid B was fixed to the metal plate A. As a result, it was possible to obtain a metal plate with a built-in wood plate in which not only the surface of the wood plate intended by the present invention but also all four side surfaces were covered with the metal plate.

  The metal plate with a built-in wooden board obtained in this way is beautiful because not only the surface but also all four side surfaces following the surface are covered with the metal plate. Moreover, since there is no pointed portion at the corner of the metal plate, it is easy to handle without damaging the hand. Further, since a special device such as a laser beam generator is not necessary for the production, the production is easy. Therefore, this invention has a great practical effect.
