According to the stamping jig, when stamping a plurality of character strings, the stamping punch can be positioned by supporting it with the slide member. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-154602 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the case of stamping jigs such as those disclosed in Patent Document 1, there has been a demand for a jig that can support the identification plate and stamping mark with a simpler configuration and that can stamp the identification plate at an appropriate position by stamping. Furthermore, there has been a demand for an engraving jig that is simple in configuration and capable of engraving multiple letters and numbers at different positions on the surface of an identification plate.

[0006] An object of the present invention is to provide a stamping jig that has a simpler configuration than conventional ones and is capable of stamping an identification plate at an appropriate position by stamping. Another object of the present invention is to provide an engraving tool that has a simple structure and is capable of engraving a plurality of letters and numbers at different positions on an identification plate. [Means for solving the problem]

[0007] The above problem is solved by the stamping jig of the present invention, which is an stamping jig used when stamping the surface of an identification plate by stamping, comprising a jig body and a spacer that is detachably attached to the jig body, a lower part of the jig body having an insertion opening into which the plate can be inserted from the side of the jig body and a storage recess for accommodating the inserted plate, an upper surface of the jig body having an insertion hole that penetrates in the vertical direction and into which the stamp and spacer can be inserted from above, the insertion hole being an elongated hole in the lengthwise or widthwise direction of the jig body and formed to communicate with the storage recess, the jig body supports the plate, the stamp and the spacer by accommodating the plate in the storage recess and inserting the stamp and the spacer into the insertion hole so that they are lined up, and the spacer positions the stamp by being inserted along the longitudinal direction of the insertion hole so that they are lined up With the above configuration, it is possible to realize a stamping jig that is simpler in configuration than conventional ones and is capable of stamping an identification plate at an appropriate position by stamping. More specifically, the stamping jig has a simple structure comprising a jig body and a spacer that can be attached to and detached from the jig body. The bottom surface of the jig body is formed with a recess into which the identification plate can be inserted and accommodated, and the top surface of the jig body is formed with an insertion hole through which the stamp and spacer can be inserted in a line. With the above configuration, the identification plate is supported by the jig body, and the stamping mark is supported by the jig body and the spacer, and letters and numbers can be stamped in appropriate positions on the identification plate by hitting the stamping mark from above with, for example, a hammer. Furthermore, by attaching and detaching the spacer to the jig body and changing the insertion position of the spacer as needed, it is also possible to engrave multiple letters and numbers on the identification plate.

[0008] In this case, the spacer is inserted into the insertion hole so that it is adjacent to the stamp in the longitudinal direction of the insertion hole and aligned with the stamp, and the jig body supports the stamp and the spacer so that the insertion positions of the stamp and the spacer can be changed in the longitudinal direction of the insertion hole. With the above configuration, by changing the stamping position and the insertion position of the spacer, it is possible to accurately stamp a plurality of letters and numbers (at appropriate intervals) on the identification plate.

[0009] In this case, when the plate is accommodated in the accommodation recess, the jig body supports the plate so as to sandwich the plate in the width direction of the accommodation recess, and abuts against the tip of the plate in the insertion direction of the plate, thereby supporting the plate in a positioned state. With the above-described configuration, the identification plate can be suitably supported by the jig body, and the identification plate can be installed at an appropriate position relative to the jig body.

[0010] In this case, the accommodating recess has a first recess formed on the bottom surface of the jig body and extending from the insertion port toward the center of the jig body, and a second recess formed on the bottom surface of the jig body continuing from the first recess, formed to be shallower than the first recess, and extending toward the opposite side of the insertion port, the insertion hole is formed to communicate with the first recess, and the jig body supports the plate with the plate accommodated in the first recess and the second recess. With the above configuration, the identification plate can be easily inserted into the storage recess (first recess) of the jig body. Furthermore, by inserting the identification plate into the second recess, the identification plate can be properly supported. Furthermore, by forming the first recess deeper than the second recess, the identification plate can be easily removed from the jig body (storage recess) after being stamped with a stamp. In other words, stamping the identification plate can sometimes cause unevenness in the thickness direction of the plate, but the shape of the storage recess has been devised to make it easy to remove the identification plate even in such cases.

[0011] In this case, the accommodating recess is formed on the bottom surface of the jig body, extends from the insertion port along the bottom surface of the jig body toward the center of the jig body, and is formed with an inclination so that it becomes shallower from the insertion port toward the center of the jig body, and the inclined portion of the accommodating recess preferably extends beyond the portion of the accommodating recess that is connected to the insertion hole. With the above-described configuration, the identification plate can be easily inserted into the accommodation recess of the jig body, and after the identification plate is stamped, the identification plate can be easily pulled out from the jig body (accommodation recess).

[0012] In this case, it is preferable that the jig body is provided with permanent magnets attached to the bottom surface thereof, and that the permanent magnets are stored in left and right storage recesses formed on the bottom surface of the jig body at positions on either side of the accommodating recess, and are positioned so as not to protrude from the bottom surface of the jig body. With the above-described configuration, the jig body can be suitably placed on, for example, a metal workbench. Furthermore, by arranging the left and right permanent magnets as described above, the jig body and the identification plate can be stably placed.

[0013] In this case, the jig body has a first body portion that supports the plate, and a second body portion that is provided on the upper surface of the first body portion and formed to be narrower than the first body portion, and that supports the stamp and the spacer, the accommodating recess is formed on the side surface in the width direction of the first body portion and extends along the bottom surface of the first body portion, the insertion hole is formed through the upper surface of the second body portion and is provided as an elongated hole in a direction intersecting the extension direction of the accommodating recess, the spacer has a spacer body portion that can be inserted into the insertion hole, and left and right spacer protrusions that protrude laterally from both side surfaces of the upper part of the spacer body portion, and when the spacer is inserted into the insertion hole, the spacer protrusions abut against the edge portion of the insertion hole in the second body portion and are positioned so as to protrude more than the second body portion in the width direction of the second body portion. The above configuration allows for a more compact jig body. Furthermore, the left and right spacer protrusions can be used to stably install the spacer on the jig body. Furthermore, the left and right spacer protrusions can be used to easily lift the spacer from the jig body after stamping. [Effects of the Invention]

[0014] According to the stamping jig of the present invention, it is possible to stamp an appropriate position on an identification plate by stamping with a simpler configuration than conventional ones. Furthermore, when engraving a plurality of letters and numbers on the identification plate, it is possible to engrave them at different positions with a simple configuration.

[0016] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to an "embossing jig" that has a simple configuration and is capable of stamping an appropriate position on an identification plate by stamping.

[0017] As shown in FIGS. 1 to 4, the stamping jig 1 is a jig that holds an identification plate M and a stamp S and is used to stamp letters and numbers on the surface of the identification plate M with the stamp S. Specifically, the stamping jig 1 is placed on a workbench, the identification plate M is housed in the bottom surface of the jig body 10, and the stamp S can be inserted from the top surface of the jig body 10. At this time, a spacer 50 can be inserted together with the stamp S to position the stamp S. Then, the worker can stamp letters and numbers on the identification plate M by hitting the stamp S from above with a hammer or the like. Furthermore, by switching the insertion positions of the stamp S and the spacer 50 relative to the jig body 10, the worker can stamp a plurality of letters and numbers on the surface of the identification plate M at appropriate positions. First, the identification plate M and the stamp S will be explained, and then the stamping jig 1 will be explained in detail.

[0018] As shown in FIGS. 1 to 4, the identification plate M is an identification plate, and on the surface of the identification plate M, a print M1 consisting of a plurality of letters or numbers is engraved. The identification plate M is, for example, a metal plate, and is a matching number tag on which an identification number is engraved for managing building materials. For example, when steel materials (steel frame materials) are sent to a contractor, an identification plate M with an engraved identification number is attached to each steel material. The identification plate M can be used not only to identify building components but also as a plate for other purposes.

[0019] The identification plate M is inserted from the side of the jig body 10, accommodated in an accommodation recess 30 formed in the bottom surface of the jig body 10, and held by the jig body 10.

[0020] 1 to 4, the stamp S is a member for stamping on the identification plate M, and is also called a stamp pin. A printing portion S1 for stamping is formed on the bottom surface of the stamp S. The stamp S is held in a state where it is positioned on the upper surface of the identification plate M, and can stamp letters and numbers on the surface of the identification plate M by being struck from above with a hammer or the like.

[0021] The stamp S is inserted into the insertion hole 20 of the jig body 10 together with a plurality of spacers 50. The insertion hole 20 and the accommodation recess 30 are connected, and the stamp S is positioned directly above the portion to be stamped on the surface of the identification plate M. 2 and 3, by changing the positions of the stamp S and the spacer 50, the stamp S is inserted into a different position inside the insertion hole 20 and positioned. 4, it is possible to engrave a plurality of letters and numbers on the surface (the portion to be engraved) of the identification plate M. In this embodiment, it can be seen that the three-digit number "123" is engraved.

[0022] As shown in Figures 1 to 6, the stamping jig 1 comprises a jig body 10 having a three-dimensional shape that is elongated in one horizontal direction, a spacer 50 that is detachably attached to the top surface of the jig body 10, and a permanent magnet 60 that is fixed to the bottom surface of the jig body 10. An insertion hole 20 penetrating in the vertical direction is formed in the top surface of the jig body 10, and an accommodating recess 30 and a storing recess 40 are formed in the bottom surface of the jig body 10.

[0023] The jig body 10 has a first body portion 11 having a rectangular parallelepiped shape that is elongated in one horizontal direction, and a second body portion 12 that is provided on the upper surface of the first body portion 11, is smaller than the first body portion 11 in the length and width directions of the first body portion 11, and has a rectangular parallelepiped shape. As shown in Figure 6, the bottom surface of the first main body portion 11 is formed with an accommodating recess 30 extending in the width direction of the first main body portion 11, and left and right storage recesses 40 formed at positions sandwiching the accommodating recess 30. An insertion hole 20 is formed in the upper surface of the second main body portion 12, penetrating in the vertical direction.

[0024] The insertion hole 20 is a long hole in the longitudinal direction of the jig body 10, and has a length and width that allow the stamp S and the spacer 50 to be inserted from above. The insertion hole 20 penetrates in the vertical direction and communicates with the accommodation recess 30 . Specifically, as shown in FIG. 7, the insertion hole 20 is formed so as to penetrate the upper surface of the second main body portion 12, and is formed as a hole that is elongated in a direction intersecting the extension direction of the accommodation recess 30.

[0025] In this embodiment, one stamp S and two spacers 50 are inserted inside the insertion hole 20, but this is not particularly limited. For example, two stamps S and one spacer 50 may be inserted. Alternatively, a shorter hole may be formed so that one stamp S and one spacer 50 are inserted therethrough, or a longer hole may be formed so that multiple stamps S and multiple spacers 50 are inserted therethrough.

[0026] The accommodation recess 30 is formed in the bottom portion of the jig body 10, has an insertion opening 31 into which the identification plate M can be inserted from the side of the jig body 10, and is a recess that accommodates the inserted identification plate. As shown in Figures 6 to 8, the accommodating recess 30 has an insertion port 31, a first recess 32 extending from the insertion port 31 toward the center of the jig body 10, and a second recess 33 that is continuous with the first recess 32, is formed to be shallower than the first recess 32, and extends toward the opposite side of the insertion port 31. Between the first recess 32 and the second recess 33, a step portion 34 is formed.

[0027] The insertion port 31 is a portion into which the identification plate M is inserted, and is formed on the side surface of the bottom portion of the jig body 10. 6, the insertion opening 31 has a tapered shape, and is formed so that the width becomes narrower from the side surface toward the center of the jig body 10. This makes it easier to insert the identification plate M.

[0028] 7 and 8, the accommodating recess 30 extends from the insertion opening 31 along the bottom surface of the jig body 10 toward the center of the jig body 10. The accommodating recess 30 is formed with an inclination so that it becomes shallower from the insertion opening 31 toward the center of the jig body 10. Specifically, the first recess 32 corresponds to the inclined portion of the accommodating recess 30, and extends beyond the portion of the accommodating recess 30 that communicates with the insertion hole 20. In other words, the bottom surface of the first recess 32 forms an inclined surface 32a. Therefore, the identification plate M can be easily inserted through the insertion port 31 and the first recess 32. Furthermore, after the identification plate M is stamped, the identification plate M can be easily pulled out of the receiving recess 30. In addition, in order to make it easier to remove the identification plate M from the storage recess 30 after the stamping operation, minute irregularities may be formed on the bottom surface of the first recess 32 (or the bottom surfaces of the first recess 32 and the second recess 33) to increase the surface roughness.

[0029] 7 and 8, the second recess 33 is formed to be shallower than the first recess, and supports the tip portion of the identification plate M from above, thereby positioning the identification plate M. In other words, the second recess 33 functions as an anti-slip device for the identification plate M. As described above, the first recess 32 makes it easy to insert the identification plate M, and the second recess 33 allows the identification plate M to be stably supported. Furthermore, stamping the identification plate M may cause unevenness in the thickness direction of the plate, but the shapes of the first recess 32 and the second recess 33 are designed to make it easy to pull out the identification plate M even in such cases.

[0030] The step portion 34 is a portion formed between the first recess 32 and the second recess 33, and is located on the second recess 33 side of the portion of the accommodating recess 30 that communicates with the insertion hole 20. Since the step portion has an inclined surface, the identification plate M can be smoothly inserted into the receiving recess 30. In other words, the identification plate M can be prevented from getting caught on the step portion .

[0031] As shown in FIG. 6, the storage recess 40 is a recess for storing a ring-shaped permanent magnet 60, and a plurality of storage recesses 40 are formed so as to surround the accommodation recess 30. A permanent magnet 60 is stored and fixed in the storage recess 40. Specifically, the permanent magnet 60 is fastened with a screw. The permanent magnets 60 are arranged so as not to protrude from the bottom surface of the jig body 10. This allows the jig body 10 to be detachably placed on a metal workbench. Furthermore, by arranging the left and right permanent magnets 60 as described above, the jig body 10 and the identification plate M can be stably placed.

[0032] As shown in FIGS. 1 to 4, the spacer 50 is a member for positioning the stamp S, and is inserted into the insertion hole 20 together with the stamp S. The spacer 50 is adjacent to the stamp S in the longitudinal direction of the insertion hole 20 and is inserted into the insertion hole 20 so as to be aligned with the stamp S, thereby positioning the stamp S. The spacer 50 is T-shaped and has a spacer main body 51 that can be inserted into the insertion hole 20, and left and right spacer protrusions 52 that protrude laterally from both side surfaces of the upper part (upper end) of the spacer main body 51. In this embodiment, two spacers 50A and 50B are used.

[0033] 8, when the spacers 50A and 50B are inserted into the insertion holes 20, the spacer main body 51 passes through the insertion holes 20 formed in the second main body 12 of the jig main body 10 and extends to reach the insertion holes 20 formed in the first main body 11. In addition, the spacer main body 51 is positioned so as not to reach the accommodating recess 30. This increases the contact area between the spacers 50A, 50B and the inner surface of the insertion hole 20, thereby stably installing the spacers 50A, 50B. On the other hand, contact of the spacers 50A, 50B with the identification plate M can be prevented.

[0034] As shown in Figures 2, 3, and 8, when the spacers 50A and 50B are inserted into the insertion holes 20, the left and right spacer protrusions 52 abut against the edge portions of the insertion holes 20 of the second main body portion 12 and are positioned so as to protrude beyond the second main body portion 12 in the width direction of the second main body portion 12. Therefore, the left and right spacer protrusions 52 can be used to stably install the spacers 50A and 50B on the jig body 10. In addition, the left and right spacer protrusions 52 can be used to easily lift the spacers 50A and 50B from the jig body 10 after stamping.

[0035] In the above configuration, as shown in Figures 2 to 4, the jig body 10 supports the identification plate M, the stamp S, and the spacer 50 by accommodating the identification plate M in the accommodating recess 30 and inserting the stamp S and the spacer 50 into the insertion hole 20 so that they are aligned. The jig body 10 supports the stamp S and the spacer 50 so that the insertion positions of the stamp S and the spacer 50 can be changed in the longitudinal direction of the insertion hole 20. In this way, by striking the stamp S from above with a hammer, for example, it is possible to stamp letters and numbers at appropriate positions on the identification plate M. Furthermore, by attaching and detaching the stamp S and the spacer 50 to the jig body 10 and changing their insertion positions as appropriate, it is possible to stamp multiple letters and numbers at appropriate intervals on the identification plate M.

[0036] In the above configuration, as shown in FIG. 8, when the identification plate M is accommodated in the accommodation recess 30, the jig body 10 supports the identification plate M so as to sandwich the identification plate M in the width direction of the accommodation recess 30, and abuts against the tip of the identification plate M in the insertion direction of the identification plate M, thereby supporting the identification plate M in a positioned state. This allows the jig body 10 to stably install the identification plate M at an appropriate position.

[0037] <Stamping method using a stamping jig> Next, an engraving method using the engraving jig 1 will be described with reference to FIGS. The method includes at least a "preparation step," an "installation step," a "first stamping step," a "position change step," a "second stamping step," and a "removal step." These steps will be explained in detail below. In addition, explanations of the steps of the stamping operation other than those described above will be omitted.

[0038] In the "preparation process," a worker prepares the components necessary for the stamping process on a workbench (step 1). Specifically, as shown in FIG. 1, the worker prepares a jig body 10, a plurality of spacers 50, an identification plate M, a plurality of stamps S, and a hammer (stamp jig).

[0039] In the "installation process," as shown in Fig. 2, an operator inserts the identification plate M from the side of the jig body 10 into the accommodation recess 30 formed in the bottom surface of the jig body 10. Then, the operator inserts the stamp S and the spacer 50 into the insertion hole 20 formed in the top surface of the jig body 10 (step 2). At this time, the stamp S and the spacer 50 are inserted so as to be aligned in the length direction of the insertion hole 20. The above steps position the identification plate M and the stamp S. The identification plate M is also placed so that the stamp S (printed portion S1) faces the surface of the identification plate M.

[0040] In the "first stamping step," as shown in FIG. 2, a worker stamps numbers on the surface of the identification plate M by hitting the stamp S from above with a hammer (step 3). At this time, the identification plate M is positioned and fixed by the jig body 10, and the stamp S is positioned and fixed by the jig body 10 and the spacer 50.

[0041] In the "position changing step," as shown in FIGS. 2 and 3, the worker changes the insertion positions of the stamp S and the spacers 50A and 50B relative to the jig body 10 (step 4). In this way, multiple numbers can be engraved on the identification plate M at appropriate intervals. Then, in the "second stamping step", similar to the "first stamping step", the worker stamps the numbers on the surface of the identification plate M by hitting the stamp S from above with a hammer (step 5).

[0042] In the "removal step", as shown in FIG. 4, the worker pulls out the identification plate M from the side of the jig body 10, and also removes the stamp S and the spacers 50A and 50B upward (step 6). After the above process, a number of numbers are engraved on the identification plate M. In addition, when a three-digit number is engraved on the identification plate M, the stamping process is performed three times.

[0043] According to the stamping method using the stamping jig 1, it is possible to stamp an appropriate position on the identification plate M using a stamping jig 1 with a simpler configuration than conventional ones.

[0044] <Other embodiments> In the above embodiment, as shown in FIG. 2, the jig body 10 has the first body portion 11 and the second body portion 12, but this is not particularly limited. For example, the jig body 10 may have a simple rectangular parallelepiped shape.

[0045] In the above embodiment, as shown in FIG. 2, the insertion hole 20 is formed as a long hole in the length direction of the jig body 10, but it may also be formed as a long hole in the width direction of the jig body 10. Furthermore, although the accommodating recess 30 is formed on the bottom surface of the jig body 10, it may be formed on the side surface of the lower part of the jig body 10 (it does not have to be formed on the bottom surface of the jig body 10). In that case, the accommodating recess 30 is preferably formed in the shape of a slit on the side surface of the jig body 10.

[0046] In the above embodiment, the stamping jig and the stamping method using the stamping jig according to the present invention have been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention naturally includes equivalents thereof. [Explanation of symbols]
