Description

  The present invention relates to an embossing apparatus that performs three-dimensional processing on a leather-like material.

  In recent years, with the widespread use of 3D printers, it has become easier to produce 3D objects, and anyone can easily design 3D objects. Against this backdrop, opportunities for commercialization based on self-made 3D objects have become familiar, and there are increasing opportunities for designers to send their designs to the world in various genres.

  On the other hand, a certain number or more of duplicates must be manufactured for commercialization. When manufacturing a product that embodies a desired three-dimensional model, for example, a mold is produced based on the three-dimensional model and injection is performed. It is widely known that a duplicate is produced by molding or an embossing method.

  However, conventional mold production requires technical equipment and experience in addition to specialized equipment, so it is common to place an order with a company that specializes in mold production, and the designer himself creates the mold. The fact is that almost nothing has been done.

In addition, mold production usually involves high costs, and it is not uncommon for cases to exceed 1 million yen. The initial investment with uncertain sales volume is high risk, and organizations and individuals with poor resources often give up product production because of mold production costs. Even if the cost can be generated, a new mold fee is generated each time the design is changed, so it is not suitable for a small quantity and a wide variety of products.
On the other hand, when a company or other capitalist who can luckily evaluate his / her design appears, it is often required to transfer the design, and the designer himself is rarely involved in commercialization. There are few cases where you can directly feel how well the design is accepted by consumers.

  This situation has been pointed out from the viewpoint of cultivating the design ability of designers. In other words, considering the cost of expensive molds, a certain amount of sales must be anticipated, so there is no denying the tendency for designs to be accepted by everyone. In that case, the designer's personality that should be freely designed according to the sensibility is buried, and as a result, the ability to design is not developed and the attractiveness of products in the market cannot be provided.

  A technology that allows designers to fully demonstrate their personality to provide products that are attractive to the market, and release them as much as possible from a management perspective. Based on this, there has been a demand for a technique that can easily and inexpensively produce a mold and can reliably produce a certain number of copies.

  As a well-known technique, after producing a female mold using synthetic resin based on the original plate, a male type is produced again using the female mold as an original plate, and embossing is performed on the work material using both male and female molds. A method is known (Patent Document 1).

However, although the technique described in Patent Document 1 makes it easy to mold from an original using a synthetic resin, it is a conventional technique in that it produces two types, a female type and a male type, based on the original. Does not leave the area. Further, there is no disclosure or suggestion about a specific approach for preventing the deviation between the male and female dies at the time of embossing, which is the final purpose, and further about attaching the strength of the embossing partially with a single press.
Under such technical background, there has been a long-awaited embossing technique that makes it easy to produce molds and can repeatedly and stably perform embossing processes, and can give subtle expressions, that is, partial strength. It was.

JP 7-138600 A

[Leather-like material]
The leather-like material R in the present invention refers to synthetic leather and other leather-like materials in addition to genuine leather, and is not particularly limited as long as the present invention can be used.

Next, the process in a present Example is demonstrated.
First, a three-dimensional modeled object based on a desired design is produced, and this is fixed as a male mold 20 to a substantially central portion of the support 10 (FIG. 1). The fixing method is not particularly limited, but it should be firmly fixed in consideration of the embossing process to the leather-like material that repeats a certain number of times after the subsequent process, that is, the female mold forming process to the shape retaining material. Is desirable.

  Next, the shape-retaining material 40 is softened at a temperature of about 70 ° C. to 80 ° C., and directly spread over the male mold 20 so as to cover it. What is necessary is just to change the said temperature suitably according to a working environment.

  After confirming that the shape retaining material 40 is in close contact with the male mold 20, the pressing body 30 having the female retaining structure 31 on the lower surface is lowered along the sliding member 50. In a state where it is lowered to a predetermined position, screws are fastened with four sliding members 50 (not shown) until solidified by cooling or the like, and the pressurized state (FIG. 3A) is maintained.

  After a predetermined time has elapsed, a female-type held structure 41 (FIG. 2B), which is the inverted shape of the female-type holding structure 31, is transferred to the upper surface of the shape-retaining material 40, and the shape-retaining material 40 has a lower surface. The male inverted shape 42 (FIG. 3B) is transferred.

  Next, the three-dimensional stamping process on the leather-like material R will be described with reference to FIGS. 4 and 5. First, as shown in FIG. 4, the leather-like material R that is a molding object is humidified and softened to some extent, and then spread on the male mold 20. At this time, the degree of humidification may be appropriately determined depending on the material R, work environment, and the like.

  Next, the pressing body 30 including the female die 40 whose position and orientation are determined by the female holding structure 41 fitted to the female holding structure 31 is gradually pressed downward onto the spread material R. At this time, during the time until plastic deformation is completed, the pressing body 30 is screwed with four sliding members 50 (not shown) at a predetermined position, and the pressurized state (FIG. 5A) is maintained. .

  Several hours later, after the plastic deformation of the leather-like material R is completed, the pressing body 30 is moved upward along the sliding member 50 together with the female die 40, the leather-like material R is taken out, and the stamping process is finished. (FIG. 5B).

[Example 2]
A second embodiment of the present invention will be described.
FIG. 6 is a partial schematic view of an embossing molding apparatus according to a second embodiment of the present invention, which differs from the previous embodiment in that an auxiliary member 60 is used, but other configurations are the same as those of the previous embodiment. Similar to the example.

  FIGS. 7A to 7C show the configuration of the auxiliary member 60, which includes a protrusion 61 at the top, a leg 63 around the collar 62 downward, and an opening 64.

  8A, the pressing body 30 is moved toward the support body 10 by a sliding member 50 (not shown), and a constant pressure is applied downward to the shape retaining material 40, to the male mold 20 and to this. It is a fragmentary sectional view which shows a mode that the reverse shape of the auxiliary member 60 of the fitted state is transcribe | transferred. FIG. 8B is an explanatory view showing a transfer surface of the shape-retaining material 40 after transfer obtained by this process.

  FIG. 9 shows that the leather-like material R, which is a molding object, is moistened and softened to a certain extent in order to perform the embossing molding, and then spread on the male die 20 and shows the positional relationship with the auxiliary member. It is explanatory drawing.

  In FIG. 10, the pressing body 30 is moved toward the support body 10 by a sliding member 50 (not shown), and is pressed against the leather-like material R that is a three-dimensional object by applying a certain pressure downward. It is a fragmentary sectional view which shows a mode that molding is performed.

  Next, the steps in the present embodiment will be described focusing on the auxiliary member 60.

[Auxiliary members]
The auxiliary member 60 is a member used for assisting the elastic material female die 40 in the embossing molding apparatus of the present invention, and transfers the inverted shape of a part of the male surface to the leather-like material R more clearly. Is for.
The material is a hard material as in the male type. In this embodiment, ABS is used as a material and is produced in a desired shape by a 3D printer in advance. The material and method are not limited to this, and any material suitable for the purpose of the present invention, i.e., a certain hard material that can withstand the embossing process to a leather-like material, other synthetic resins, metals, silicon, ceramics, A desired material such as wood can be used.

The lower part of the auxiliary member 60 has a shape that substantially fits into a male partial shape. At this time, if the fitting state of both members, that is, the inner diameter of the concave portion of the upper portion of the male mold 20 and the outer diameter of the auxiliary member leg portion 63 are fitted with no allowance, a tensile tension is applied to the leather-like material, and clear three-dimensional processing is performed. It is hard to give. Furthermore, the leather-like material may be damaged by the tension.
Therefore, in this embodiment, the thickness of the leather-like material is considered for the difference between the inner diameter of the concave portion of the male mold 20 and the outer diameter of the auxiliary member leg portion 63, and the depth of the concave portion of the male mold 20 and the auxiliary member leg portion 63. Considering the thickness of the leather-like material per length, it is characterized by ensuring a sufficient fitting state. In addition, it is preferable to design the male type and the auxiliary member according to the type and thickness of the leather-like material.

The use of the protrusion 61 of the auxiliary member 60 will be described.
In the embossing process on the leather-like material, the auxiliary member 60 is fitted into the concave portion 42 of the female die 40. When the auxiliary member 60 is taken out from the concave portion 42, the protrusion 61 is used. That is, the female die 40 with the auxiliary member 60 fitted thereon is removed from the pressing body 30, and the auxiliary member 60 is removed from the outside of the female die 40 in contact with the pressing body 30 on the extension line of the protrusion 61. When pushed in the direction, the auxiliary member 60 can be easily removed.
The female die 40 needs to be replaced after a certain number of stamping processes due to its material. At this time, the operation of replacing the auxiliary member 60 to a new female die by the protrusion 61 becomes easy.

  In this embodiment, in order to mold the female mold into the shape retaining material 40, the shape retaining material 40 softened at a temperature of about 70 ° C. to 80 ° C. is fitted to the male shape 20 and a partial shape of the male shape. The auxiliary member 60 is directly spread so as to cover the auxiliary member 60. The temperature may be changed as appropriate according to the working environment, as in the above embodiment.

  After confirming that the shape-retaining material 40 is in close contact with the male member 20 and the auxiliary member 60 in a state of being partially fitted to the male member, the pressing body 30 having the female retaining structure 31 on the lower surface is provided. It goes down along the sliding member 50. In the state lowered to a predetermined position, the four sliding members 50 are screwed to maintain the pressurized state (FIG. 8 (a)) until solidified by cooling.

  After a predetermined time has elapsed, the inverted shape of the male mold 20 and the auxiliary member 60 is transferred to the lower surface of the shape retaining material 40 (FIG. 8B), and as in the previous embodiment, the upper surface of the shape retaining material 40 is The female-type held structure 41, which is the inverted shape of the female-type holding structure 31, is transferred.

Subsequently, a three-dimensional stamping process on the leather-like material R in the present embodiment will be described with reference to FIGS. 9 and 10.
First, as shown in FIG. 9, the leather-like material R that is a molding object is humidified and softened to some extent, and then spread onto the male mold 20. At this time, the degree of humidification may be appropriately determined depending on the material R, work environment, and the like.
Next, the female die 40 whose position and orientation are determined by the female-type held structure 41 fitted to the female-type holding structure 31 on the spread material R, and in which the auxiliary member 60 is fitted. 40 is gradually pressed downward. At this time, during the time until plastic deformation is completed, the pressing body 30 is screwed with four sliding members 50 (not shown) at a predetermined position, and the pressurized state is maintained.

  A few hours later, after the plastic deformation of the leather-like material R is completed, the pressing body 30 is moved upward along the sliding member together with the female die 40, and the leather-like material R is taken out. A leather-like material that is clearly embossed from the part is obtained.

As mentioned above, according to a present Example, since a part of male type | mold is stamped between hard materials, the surplus part (embossing part with a hard material and the female type | mold with fixed elasticity) It is possible to perform a clear stamping process as compared with the above.
In addition, it is good also as the auxiliary member in a present Example covering not only a part of male type | mold surface but the whole surface.

[Modification 1]
Next, a second embodiment of the present invention, that is, a modification of the embodiment using the auxiliary member will be described. FIG. 11 is an explanatory view showing a convex member 70 used in this modification.
The convex member 70 includes a male die 72 and an auxiliary member 71. A protrusion 711, an engaging portion 712 and a leg portion 713 are formed on the top of the auxiliary member 71. On the other hand, the male mold 72 is formed with an engaging portion 721 that fits into the engaging portion 712.
The leg portion 713 and the upper opening 722 of the male die 72 are designed to be in a fitted state with a margin, as in the second embodiment.

  The male mold 72 in this modification corresponds to the male mold 20 in the above embodiment, and the auxiliary member 71 corresponds to the auxiliary member 60 in the above embodiment. By providing the engaging portion 712 and the engaging portion 721 as in this modification, in addition to being able to give a wide variety of embossed patterns, the male die and the auxiliary member are mutually connected during the female die molding process. It is possible to improve work efficiency without shifting.

[Modification 2]
In the present invention, the pressing body 30 is pushed down to perform a pressing process in anticipation of a certain elastic deformation rate derived from the material of the female mold 40, but in the case of a molding object exceeding a certain thickness, Since there is a possibility that excessive pressure is applied, the following modification is effective.

In other words, in the case of the above-described modification example 1, in the case of the female mold processing, instead of the convex member 70, a member having an outer shape of the convex member 70 and having a height only increased by a certain value (in this paragraph) Using a “provisional convex member (not shown)”, a female die 40 having a deep recess is formed (rather than forming a female die with the convex member 70), and embossing a leather-like material The convex member 70 is sometimes used.
As a result, even when a molding object having a certain thickness or more is embossed, by using the convex member 70, an excessive pressing load on the molding object is imposed by the female mold in which the concave part is molded deep by a certain value. Therefore, the effect of preventing the material from being broken can be expected.
Since the periphery of the female die is open and a part of the pressure due to the downward pressing of the pressing body 30 escapes in the lateral direction, only the height needs to be considered for the design of the temporary convex member.

  The embossing molding apparatus and the embossing method of the present invention are preferably used for, for example, three-dimensional molding such as a coin purse using a leather-like material, but are not particularly limited thereto.
