  The stamping device described in Patent Document 1 holds a stamping punch with a stamping holder, and inserts a positioning pin provided in the stamping holder into a positioning hole provided in a positioning jig, thereby performing the stamping punch. It is for positioning. Specifically, a large number of positioning holes are formed at a predetermined pitch in the marking arrangement direction, and each time the marking is completed, the positioning pin of the marking holder is removed from the positioning hole, and the positioning holes at the next marking position are removed. By inserting the punch insertion hole, the punch insertion hole is moved. However, it takes time and labor to insert and remove the positioning pins into and from the positioning holes for each marking. In addition, since a large number of positioning holes are provided, if the holes for inserting the positioning pins are mistaken, there is a risk of being stamped in the wrong place.

  Therefore, in view of the above problems, the present invention provides a stamping jig that can easily and accurately position a stamping punch when stamping a plurality of characters or the like manually. Let it be an issue.

  In order to solve the above-described problem, the stamping jig according to claim 1 is a stamping jig for marking a character string with a stamping punch on a workpiece, and is long in the arrangement direction of the character strings. A main body having a through hole and a plurality of slide members arranged in the arrangement direction of the character string and movable in the arrangement direction of the character string inside the through hole, and a wall surface and a slide forming the through hole A punch insertion hole through which the stamping punch is inserted is formed on the side surface of the member.

  With the above configuration, the punch insertion hole into which the stamping punch is inserted is formed by the wall surface forming the through hole and the side surface of the slide member. Therefore, the movement of the punch insertion hole moves the slide member in the arrangement direction of the character strings. It can be done easily by moving. In addition, since the punch insertion hole is moved by sliding the slide member, the stamping punch can be accurately positioned without being stamped at an incorrect position due to an incorrect insertion of the positioning pin.

  The stamping jig according to claim 2 is characterized in that the slide member is made of a magnetic metal, and a magnet is provided on a contact surface between the main body portion and the slide member.

  With the above configuration, each slide member is attracted and fixed by a magnet, and therefore, even if the stamping jig is used while being inclined in the moving direction of the slide member, the slide member moves toward the insertion hole by its own weight. The state in which the insertion hole is formed can be reliably maintained.

  As described above, according to the stamping jig of the present invention, the stamping punch can be easily and accurately positioned when stamping a plurality of characters or the like manually.

In the present embodiment, as shown in FIG. 2, the through hole V is formed by the through hole 11 a provided in the upper member 11 and the through hole 12 a provided in the lower member 12. The through hole 11a of the upper member 11 and the through hole 12a of the lower member 12 have the same shape and size, and are provided at the same position in plan view (see FIG. 4).

  The main body portion 10 is provided with a lateral hole H that communicates with the through hole V and opens on the side surface of the main body portion 10. In the present embodiment, the lateral hole H penetrates the main body portion 10 in the width direction, and communicates the through hole V with the side surfaces on both sides in the width direction of the main body portion 10. For example, as shown in FIG. 2, a recess 11 b is formed on the lower surface of the upper member 11, and a lateral hole H can be formed by the recess 11 b and the upper surface 12 b of the lower member 12.

  The plurality of slide members 20 are arranged in the longitudinal direction inside the main body 10 and are each slidable in the longitudinal direction. As shown in FIG. 3, each slide member 20 integrally includes a prismatic vertical portion 21 extending in the vertical direction and a prismatic horizontal portion 22 extending from the vertical intermediate portion of the vertical portion 21 to both sides in the width direction. Form a cross. The vertical portion 21 is fitted into the through hole V, whereby the slide member 20 and the main body portion 10 are engaged in the width direction, and the width direction is prevented from coming off. The horizontal portion 22 is fitted into the horizontal hole H, whereby the slide member 20 and the main body portion 10 are engaged in the vertical direction, and the vertical direction is prevented from coming off. Moreover, as shown in FIG. 4, the flat side surfaces 21a on both sides in the width direction of the vertical portion 21 are fitted between the flat inner walls of the through holes V (through holes 11a and 12a), whereby each slide member 20 is fitted. Rotation around the vertical direction is restricted, and each slide member 20 can be slid in parallel.

  As shown in FIG. 4, the horizontal portion 22 of the slide member 20 protrudes from the main body portion 10 on both sides in the width direction. An inclined surface 22 a is provided at the tip of the horizontal portion 22. A concave portion B is formed by the inclined surface 22a of the horizontal portion 22 of the adjacent slide member 20, and the movement operation of the slide member 20 is facilitated by the concave portion B.

  The punching jig 1 is provided with a punch insertion hole A for inserting a stamping punch. In the present embodiment, as shown in FIG. 4, the punch insertion hole A is formed by the wall surface that forms the through hole V of the main body 10 and the side surface of the slide member 20. Specifically, as shown in FIG. 5, a punch insertion hole is formed by the wall surface of the through hole 11 a of the upper member 11, the wall surface of the through hole 12 a of the lower member 12, and the side surface 21 b of the vertical portion 21 of the slide member 20. A is formed. A plurality of slide members 20 are arranged in a region excluding the punch insertion hole A in the through hole V of the main body 10.

To do.

  Next, the operation of the stamping work using the stamping jig 1 according to the present invention will be described. The worker attaches the attachment member 40 as described above, and fixes the stamping jig 1 to the workpiece. Then, stamps such as letters necessary for stamping are prepared, and stamps P such as the corresponding letters are inserted into punch insertion holes A formed with a plurality of slide members 20 brought to one side (see FIG. 5), the character or the like is engraved by hitting the end of the engraving punch with a hammer.

  Subsequently, the engraved punch P is extracted from the punch insertion hole A, the slide member 20 is moved in the horizontal direction, and the position of the punch insertion hole A is moved by one character. Thereafter, a stamp P for the next character or the like is inserted into the punch insertion hole A (see FIG. 6), and is similarly stamped with a hammer. This operation is repeated for the required number of characters, and a series of character strings are sequentially stamped.

  Thus, in order to support the stamp punch P to be inserted by the punch insertion hole A formed by the wall surface forming the through hole V of the main body portion 10 and the side surface 21b of the slide member 20, the slide member 20 is arranged in one piece. By sequentially moving the punch insertion holes A one by one, it is possible to easily move the punch insertion hole A, and it is possible to easily and accurately position the stamp punch P at the place where each character is to be stamped. As a result, it is possible to quickly perform marking of characters and the like on the workpiece at an accurate stamping position, and work efficiency can be improved.

  Next, other embodiments of the stamping jig 1 according to the present invention are shown in FIGS. In addition, about the member, component, etc. which have the same function or shape as the above-mentioned embodiment, the detailed description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  In the present embodiment, the main body 10 includes an upper member 11, a lower member 12, and a slide guide member 30, and the main body 10 is assembled to the attachment member 40. As shown in FIGS. 7A and 7B, since the slide guide member 30 is also assembled to the lower member 12, the size is larger than that of the main body 10 in the above-described embodiment.

  The slide guide member 30 is a plate-like rectangular member, and a thin plate-like magnet 30 a is attached to a surface in contact with the slide member 20. The lower member 12 and the slide guide member 30 are assembled by an assembly screw 31 via a sleeve 31a, and are further screwed to the attachment member 40. The sleeve 31 a has a height obtained by adding the thickness of the magnet 30 a to the height of the slide member 20.

  FIG. 8 is a perspective view of the slide member 20. The slide member 20 in the present embodiment is a magnetic metal, and has an adsorption surface 22b that is adsorbed by a magnet 30a provided on the slide guide member 30 by extending one horizontal portion 22 in the width direction. doing.

  In FIG. 9, the top view of the state which assembled | attached the main-body part 10 and the several slide member 20 is shown. The slide member 20 can be held by adsorbing the adsorption surface 22b of the slide member 20 by the magnetic force of the magnet 30a attached to the slide guide member 30.

  FIG. 10 shows a state in which the stamping jig 1 is attached to the engine block E that is a workpiece. A pin hole 40a provided in the attachment member 40 is inserted into a pin (not shown) provided in the engine block E, and is screwed into a screw hole portion (not shown) with a mounting screw 42 via a washer 41, thereby making an engraving cure. The tool 1 is fixed to the engine block E in an inclined state.

  The operation of the stamping operation using the stamp punch is the same as that of the above-described embodiment. By attaching the magnet 30 a to the slide guide member 30, the slide member 20 can be attracted by a magnetic force, so that the embossing jig 1 is attached to an inclined surface inclined in the moving direction of the slide member 20. However, the slide member 20 does not move by its own weight, and the work can be performed in a state where the punch insertion hole A is formed reliably.

  In the present embodiment, an example in which the thin plate-like magnet 30a is attached to the slide guide member 30 is shown. However, the present invention is not limited to this, and the entire slide guide member 30 or an area in contact with the slide member 20 can be used. You may comprise a part with a member which has magnetic force. Further, the main body 10 may be made of a magnetic metal, and a magnet may be attached to the slide member 20, or the slide member 20 may be composed of a magnet. The strength of the magnetic force that attracts the slide member 20 is preferably strong enough that the slide member 20 does not move due to its own weight even when the embossing jig 1 is attached in an inclined state.

  Moreover, the shape of the attachment member 40, and the number and position of the pin hole 40a and the screw hole 40b can be suitably changed according to the shape of the workpiece.

  Next, other embodiments of the stamping jig 1 according to the present invention will be described.

  The thickness of the slide member 20 in the longitudinal direction can be set as appropriate according to the interval of the characters to be engraved. Since the stamping punch has characters or the like carved at the thinned tip, if the stamping punch is stamped at intervals of the stamping punch, the spacing of the characters or the like will be more than necessary. Therefore, for example, by making the thickness of the slide member 20 smaller than the thickness of the marking punch in the character string direction, the spacing of characters and the like can be more compactly stamped than the spacing of the marking punch.

  Further, as shown in FIG. 11A, the slide member 20 is provided with a slope 21c on the side surface 21b side of the vertical portion 21 above the slide member 20 as a guide for inserting the stamp punch into the punch insertion hole A. May be. Further, as shown in FIG. 11 (b), the length of the horizontal portion 22 of the slide member 20 is made the same as the length of the horizontal hole H of the main body portion 10, the length of the vertical portion 21 is lengthened, and the upper end is penetrated. You may make it protrude from the hole V. FIG. By doing in this way, the inclination 21c of the perpendicular | vertical part 21 which protruded from the through-hole V can be used as an operation part at the time of the insertion guide of an engraving punch, and an operator moving the slide member 20. FIG.

  Furthermore, in the embodiment of the present invention, since the slide member 20 moves inside the through hole V of the main body portion 10, a member having good slidability is used at a portion where the main body portion 10 and the slide member 20 are in contact with each other. Also good. In order to further improve the slidability, the surface may be subjected to smoothing or fluorine coating, or a low friction member may be attached to the sliding portion. Thereby, since the slide member 20 can be easily slid, the workability of the stamping operation is improved.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
