Description

In the present invention, for example, when forming packaging containers by folding various sheet members such as cardboard, corrugated paper, and plastic sheets, a folding ruled line is formed on the sheet material that becomes the packaging material. The present invention relates to an aligning device for a surface plate that can be positioned and fixed accurately on a cutting plate by matching a surface plate for punching and forming from a sheet member with a die-type cutting blade or ruled line blade position.

  Conventionally, when various packaging containers are made of sheet material punched from a sheet member, the sheet material is punched from the sheet member with a cutting line corresponding to the outer shape of the packaging container and at the same time a ruled line corresponding to the folding line is formed. Form on the material. That is, a cutting blade corresponding to the cutting line, a die mold embedded in a state in which each blade part of the ruled line blade corresponding to the ruled line is taken out, and an outer shape having a cutting edge along the outer shape of the sheet material, A surface plate provided with a ruled line groove for forming a ruled line is prepared, and the die mold is set on the punching machine, and the surface plate is arranged and fixed on the cutting plate surface according to the die mold, and then a sheet member is placed between them. Sheet material is obtained by placing and punching.

  When the die mold is set on the punching machine and the face plate is placed and fixed on the cutting plate surface, the cutting edge of the face plate must exactly match and correspond to the cutting blade position and the crease groove should correspond to the crease blade position. If these are not available, an accurate sheet material cannot be obtained. Therefore, various jigs and methods have been proposed in the past in order to place the face plate on the cutting plate so as to match the die-type cutting blade and the ruled line blade, for example, Patent Documents 1 to 4.

  A method for aligning a punching die and a female die of a paper container blank according to Patent Document 1 and a guide jig used therefor are provided in a concave groove when aligning a stamped die ruler and a female concave groove. A ruled line is positioned between the guide jigs or along the guide surface with respect to the guide jig arranged along the guide jig, and the face plate is bonded to the back surface of the female mold.

  In the punching machine according to Patent Document 2, the punching method and the female die mounting method, and the punching and female positioning attachment members are provided with positioning holes corresponding to the punching die and the female die, respectively, and the die positioning is performed. Attach the positioning disk to the head of the positioning pin inserted in the hole, move the upper press plate of the die to the lower press plate side of the female mold, and bond the positioning disk to the lower press plate, and bond the positioning disk The positioning hole is fitted to the female die and the female die is attached to the lower press plate.

  According to Patent Document 3, a method for attaching a die and a face plate is performed by fitting a perforated elastic body to a positioning pin inserted into a positioning hole of a die, and temporarily fixing a positioning disk, and then lowering the die side. The positioning disk is transferred to the dead plate, and after the taper pin inserted in the positioning disk is attached to the dead plate, the positioning disk is removed, and the face plate is fitted to the taper pin and fixed to the dead plate by positioning, and the taper pin is removed. .

  In the dislocation positioning jig according to Patent Document 4, a male member is assembled to a cylindrical female member fitted into a veneer plate in which a Thomson blade is incorporated, and the male member is bonded onto a cutting plate in a recess in the head of the male member. A dislocation register member is attached, and the CAD face plate is aligned with the dislocation register member that is displaced after the veneer plate is moved onto the cutting plate, and is fixed to the cutting plate.

JP 63-39793 A Japanese Patent No. 3429828 (Japanese Patent Laid-Open No. 7-17195) JP 2002-103289 A Registered Utility Model No. 3141440

  According to such a conventional method, jig, etc., in Patent Document 1, it is necessary to attach a large number of guide jigs to various portions of the female concave groove. It is difficult to obtain a stable die-cut product. In Patent Document 2, a positioning hole for inserting a positioning pin into the die is provided, and the positioning hole needs to correspond to a positioning hole similarly provided in the female die. There must be. In Patent Document 3, it is necessary to provide a positioning hole for inserting the positioning pin in the die, and the taper pin is aligned with the positioning disk temporarily fixed to the dead plate, and the face plate is aligned with this taper pin. It takes. In Patent Document 4, it is necessary to provide a hole in a veneer plate which is a die-cutting in order to fit a female member, a male member, and the like.

  In any case, when a positioning disk that serves as a mark for the mounting position of the plate is placed and bonded to the lower press plate, dead plate, etc., the positioning hole that opens in the plate must correspond to the positioning pin position. Therefore, it is necessary to set each cutting die in consideration of the ruled line position, the ruled line blade corresponding to the cutting edge outline position, and the position avoiding the cutting blade. In addition, if the positioning pin position is different for each cutting die corresponding to different sheet materials, the positioning hole position of the face plate to be fitted to the positioning disk is also different, so the corresponding position is set according to the die cutting and face plate respectively. It must be cumbersome and time consuming.

Therefore, the present invention was created in view of various circumstances that existed in the past, and its purpose is to use a general die mold (die cutting) that is not crafted to align with the face plate. It should be possible to accurately align with the surface plate fixed on the cutting plate without requiring any special processing for the die mold. Specifically, the positioning disk is arranged by setting the positional relationship with respect to the ruled line blade or cutting edge, for example, corresponding to the ruled line position and cutting edge outline position on the surface slab manufactured according to the die-cut product (sheet material) The die die itself does not require any processing, and the use of the die die itself allows the face plate to be reliably and accurately positioned and fixedly set on the cutting plate. In addition, since the positioning disk position can be set to a fixed position by the ruled line blade or the cutting blade position, the positioning hole position formed in the surface plate can also be set in advance by the ruled line groove and the cutting edge position formed in the surface plate itself. , Making it easy to create face plates. Furthermore, it is intended to provide a positioning device for a surface plate that can greatly improve handling and workability because the positioning disk position set in the die mold and the positioning hole position in which the opening is formed in the surface plate inevitably match. is there.

In order to solve the above-mentioned problems, the surface plate positioning method according to the present invention is performed in the vicinity of the intersecting portion of the ruled line blade 11 or the cutting blade 12 in the die mold 10 in which the ruled line blade 11 and the cutting blade 12 are arranged. The positioning support board 1 is supported by positioning it on the ruled line blade 11 or the cutting blade 12, and after the positioning disk 6 is mounted on the positioning support board 1, the die mold 10 is moved and abutted on the cutting plate 20 so that the positioning disk 6 is moved. The surface plate 15 is displaced to the surface of the cutting plate 20, the positioning hole 18 of the surface plate 15 is aligned with the displaced positioning disk 6, and the surface plate 15 is fixed to the cutting plate 20.
The positioning support board 1 can be supported across the ruled line blades 11 in the vicinity of the intersection of the ruled line blades 11 that are orthogonal to each other.
The positioning hole 18 of the face plate 15 is positioned near the crossing part of the ruled line groove 16 or the cutting edge 17 corresponding to the crossing part of the ruled line blade 11 or the cutting blade 12 of the positioning support board 1 attached to the die 10. In this case, an intersection point of substantially the same interval positions as the predetermined intervals x and y from the ruled line blade 11 or the cutting blade 12 with respect to the mounting position of the positioning disk 6 can be formed as the center position.
Further, the surface plate alignment apparatus according to the present invention is supported across the ruled line blade 11 or the cutting blade 12 at the intersection between the ruled line blades 11 or the cutting blades 12 intersecting each other in the die mold 10. The positioning support plate 1 and the position of the positioning support plate 1 in the vicinity of the intersection between the ruled line groove 16 or the cutting edge 17 in the surface plate 15 formed corresponding to the ruled line blade 11 and the cutting blade 12 in the die 10 And a positioning disk 6 mounted on the positioning support board 1 so as to be transferred to the cutting plate 20 and fitted with a positioning hole 18 having an opening formed at a position opposed to the cutting plate 20.
The positioning support board 1 can be supported across the ruled line blades 11 in the vicinity of the intersecting portion of the ruled line blades 11 that are orthogonal to each other.
The positioning support board 1 includes a support board body 2 having a support portion 3 that fits and supports the intersecting ruled line blades 11 or cutting blades 12 in the die mold 10, and the support board body 2 so that the positioning disk 6 is mounted. The disk connecting portion 5 formed on the surface side of the cutting plate 20 can be configured. Further, the elastic buffer portion 4 can be disposed on the surface side of the die mold 10 in the support board main body 2.
The support part 3 has a groove shape that is fitted to the edge of the ruled line blade 11 or the cutting edge 12, and is formed on the edge (a, b) of the support board main body 2 corresponding to the position of the ruled line blade 11 or the cutting edge 12. Can be formed.
The disk connecting portion 5 can be formed in a protruding shape for fitting the doughnut-shaped positioning disk 6 at a height substantially the same as the thickness of the face plate 15.
The center positions of the disk connecting portion 5 and the positioning hole 18 are the intersection angle α at the intersection of the ruled line blade 11 or the cutting blade 12, the ruled line groove 16 or the cutting edge 17 corresponding to each other between the die mold 10 and the face plate 15. It can be configured to be determined in accordance with the predetermined intervals x and y from the ruled line blade 11 or the cutting blade 12, the ruled line groove 16 or the cutting edge 17.

In the surface plate alignment method and alignment apparatus according to the present invention configured as described above, the ruled line blade 11 and the cutting blade 12 of the die mold 10 are respectively the ruled line groove 16 and the cutting edge 17 of the surface plate 15. Are arranged and formed so as to face each other, and when the face plate 15 is fixed to the cutting plate 20 so as to face each other, the ruled line blade 11 or the cutting blade 12 in the intersecting die mold 10, the ruled line groove 16 in the face plate 15 or By setting the positioning disk 6 and the positioning hole 18 with the cutting edge 17 as a reference, the die mold 10 and the face plate 15 are accurately opposed to each other.
The positioning support board 1 supported so as to straddle between the ruled line blades 11 in the vicinity of the intersecting portions of the orthogonal ruled line blades 11 does not require any special work for positioning the surface plate 15 with respect to the die mold 10. The positioning disk 6 is positioned to protect the cutting blade 12.
Further, the mounting position of the positioning support board 1 on the die mold 10 is a position in the vicinity of the intersection between the ruled line blades 11 or the cutting blades 12, and the opening position of the positioning holes 18 is relative to the ruled line grooves 16 or the cutting edges 17. If the intersection between the die mold 10 and the face plate 15 is opposite, the relative positional relationship is maintained even if the positioning is independently performed. Thus, by fitting the positioning hole 18 of the face plate 15 to the positioning disk 6 shifted to the surface of the cutting plate 20, the ruled line blade 11 is firmly opposed to the ruled line groove 16, and the cutting blade 12 is exactly aligned to the cutting edge 17. .
The positioning support board 1 is mounted across the ruled line blade 11 or the cutting blade 12 at the intersecting portion so as to straddle them, so that the position of the disk connecting part 5 is stabilized without being displaced in any direction. The positioning disk 6 is supported without being displaced. On the other hand, the positioning hole 18 that is always formed at a specific position by the ruled line groove 16 or the cutting edge 17 at the intersecting portion of the face plate 15 is not displaced.
Similarly, the center position of the disk connecting portion 5 set by the crossing angle α at the crossing portion between the ruled line blade 11 or the cutting blade 12 of the die mold 10 and the predetermined intervals x and y from the ruled line blade 11 or the cutting blade 12 is the same. , The crossing portion between the ruled line groove 16 or the cutting edge 17 in the surface plate 15, the predetermined spacing positions x and y from the ruled line groove 16 or the cutting edge 17, and the relative position of the die mold 10 and the surface plate 15 are the same. Let me.

  Since the present invention is configured as described above, when the positioning hole 18 formed in the face plate 15 is fitted and positioned on the positioning disk 6 to be displaced from the die mold 10 on the cutting plate 20, the positioning is performed on the die mold 10. The disk connecting portion 5 to which the support plate 1 is attached and set can be set at a certain specified vicinity of the crossing portion of the ruled line blade 11 or the cutting blade 12 in the die mold 10, so that the die mold 10 is not specially processed. However, the positioning disk 6 can be easily positioned and attached to the die mold 10 without troublesome work. Moreover, the positioning hole 18 of the surface plate 15 facing the positioning disk 6 positioned on the die mold 10 has a specific fixed position near the intersection of the ruled line groove 16 or the cutting edge 17 facing the ruled line blade 11 or the cutting blade 12. Even if the opening is formed by setting the position in advance, the positioning disk 6 and the positioning hole 18 can be exactly matched when the die mold 10 and the face plate 15 face each other.

  That is, in the present invention, the positioning disk 6 is supported on the die mold 10 by positioning at the crossing part of the ruled line blade 11 or the cutting blade 12 of the die mold 10, while the ruled line on the surface plate 15 corresponding to the crossing part. A positioning hole 18 is formed by positioning at the intersection of the groove 16 or the cutting edge 17, and the positioning hole 18 is fitted to the positioning disk 6 transferred on the cutting plate 20 to fix the face plate 15 on the cutting plate 20. Because. As a result, the positions of the ruled line blade 11 and the ruled line groove 16, the cutting edge 12 and the cutting edge 17 when the die mold 10 and the face plate 15 face each other exactly match each other, and a predetermined sheet material can be obtained from the sheet member S. Can be cut and formed reliably.

  Further, since the positioning support board 1 includes the support portion 3 that fits the ruled line blade 11 or the cutting blade 12, it can be easily fitted by straddling the crossing part of the ruled line blade 11 or the cutting blade 12 between them. Can be attached. Moreover, at the time of installation, the disk connecting portion 5 can always be positioned at a specified fixed position in the vicinity of the intersecting portion, and the position of the positioning disk 6 formed in the surface plate 15 is also fixed. The positioning hole 18 to be formed can be exactly matched when the die 10 and the face plate 15 face each other.

  The center positions of the disk connecting portion 5 which is the mounting portion of the positioning disk 6 in the positioning support plate 1 attached to the die mold 10 and the positioning hole 18 in the face plate 15 are the intersections of the ruled line blade 11 or the cutting blade 12 in the die mold 10. From the position of the ruled line blade 11 or the cutting edge 12 in the vicinity of the part, and on the other hand, from the position of the ruled line groove 16 or the cutting edge 17 in the vicinity of the crossing part of the ruled line groove 16 or the cutting edge 17 on the face plate 15, The intersection point of substantially the same interval position is formed as the center position. Therefore, if the crossing part is opposed between the die mold 10 and the face plate 15, the positioning disk 6 and the positioning hole 18 are exactly matched, and even if they are individually arranged and formed, cutting The face plate 15 can be fixed on the cutting plate 20 at a position facing the die mold 10 by fitting the positioning hole 18 to the positioning disk 6 transferred to the plate 20.

  In addition, when the positioning support plate 1 is attached to the intersection of the ruled line blade 11 or the cutting blade 12 in the die mold 10, the position thereof is always constant, and the position of the disk connecting portion 5, that is, the positioning disk 6 is also specified. Thus, the positioning hole 18 can be formed by determining the center position of the positioning hole 18 on the basis of the intersecting part in the surface plate 15 corresponding to the intersecting part in the die mold 10. On the contrary, if the positioning holes 18 are formed at predetermined intervals x and y from the ruled line groove 16 or the cutting edge 17 in the vicinity of the intersecting portion of the ruled line groove 16 or the cutting edge 17 at an appropriate position in the surface plate 15, the positioning is performed. When attaching the support board 1 to the die mold 10, it is sufficient to select an intersection corresponding to the position of the positioning hole 18, and a special process, for example, a conventional hole for inserting a positioning pin is opened in the die mold 10. In combination with the fact that there is no need to drill, the preparation work for positioning can be greatly reduced, and the workability can be greatly improved.

  In addition, the code | symbol attached | subjected in each means of the means for solving said subject and the effect of invention was attached | subjected in order to make easy reference with the part which shows each structure part described in drawing. The present invention is not limited to these descriptions, structures, shapes, and the like indicated by reference numerals and the like in the drawings.

It is a general | schematic disassembled perspective view of the use condition which shows one form for implementing this invention. Similarly, (a) is a plan view of the main part of a die mold to which a positioning disk is attached, and (b) is a surface plate showing a positioning hole formed in the vicinity of the crossing portion of the surface plate facing the crossing portion to which the positioning disk is attached. It is a principal part top view. It is the sectional drawing similarly. Similarly, in the sectional view showing the work procedure when aligning, (a) when it is lowered to the cutting plate after being attached to the die mold, (b) is when the positioning disk is transferred to the cutting plate, (C) is when the face plate is fixed to the cutting plate according to the positioning disk, and (d) is when the sheet material is punched from the sheet member to be loaded.

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure denotes a die mold (cutting die) in which ruled line blades 11 and cutting blades 12 are embedded in a predetermined arrangement. ) 10 is a positioning support board that is attached by being supported by the ruled line blade 11 or the cutting blade 12. This positioning support board 1 is placed on the ruled line blades 11 or cutting blades 12 that intersect each other, that is, between the ruled line blades 11, between the ruled line blades 11 and the cutting blades 12, or between the cutting blades 12, A support board body 2 having a support part 3 that fits and supports the ruled line blade 11 or the cutting blade 12 so as to straddle them, and an elastic buffer part 4 arranged on the die 10 surface side of the support board body 2 And a disk connecting portion 5 formed on the surface of the cutting plate 20 in the support board main body 2.

  The support board body 2 in the illustrated example is bridged obliquely at the intersecting portions between the ruled line blades 11 intersecting each other in the die mold 10 so as to be substantially orthogonal to each other, that is, between the ruled line blades 11 orthogonal to each other. It is formed so as to span between the ruled line blades 11 near the intersection. In this way, the support board body 2 supported across the vicinity of the intersection where the ruled line blades 11 intersect each other has the first edge a located on one side of the ruled line blades 11 arranged in an intersecting manner, and also on the other side. The second side edge b, the first side edge a, the third side edge c continuing from the crossing site side of the second side edge b, and further the first side edge a and the second side edge b. A fourth edge is provided which is continuous to the opposite side portions. The planar shape of the supporting board main body 2 in the illustrated example is formed so that the third edge is linear, and the fourth edge is shaped so as to exhibit a substantially hexagonal shape when viewed from the plane as a whole. Of course, the planar outer shape of the support board main body 2 is not limited to this, and is considered to be, for example, rectangular, 5 in consideration of workability and the like at the time of mounting support to the die 10, specifically the ruled line blade 11 or the cutting blade 12. It may be formed in a square shape or other external shape.

  The support part 3 has a first edge a positioned on the edge of the support board body 2 located on the ruled line blade 11 or the cutting blade 12, that is, in the vicinity of the intersecting part of the ruled line blade 11 or the cutting blade 12 intersected with each other. Each of the second edges b is formed in a narrow groove shape that is forcibly fitted into the edge of the ruled line blade 11 or the cutting edge 12. The groove-shaped support portion 3 has a depth that is slightly smaller than the thickness of the ruled line blade 11 or the cutting blade 12 and has a depth that overlaps with the edge of the blade edge at an appropriate height. Even if the die mold 10 itself is directed to the cutting plate 20 side so that the edge of the ruled line blade 11 and the cutting blade 12 faces downward by being fitted and supported on the edge of the blade edge, the positioning support board 1 itself is not dropped. I am doing so.

  The buffer portion 4 is formed, for example, in a shape substantially the same as that of the support plate main body 2 by, for example, a rubber plate disposed in a gap between the support plate main body 2 and the die die 10 surface, and is on the die die 10 surface side. It is affixed on the back surface of the support board body 2. In addition, in relation to the depth of the support portion 3, the buffer portion 4 abuts the die die 10 attached and supported by the positioning support board 1 on which the positioning disk 6 is mounted, in contact with the cutting plate 20 surface, as will be described later. When the positioning disk 6 is displaced to the surface of the cutting plate 20, it is provided with a thickness and elasticity that exerts an elastic action sufficient to displace it.

  The disk connecting portion 5 is formed on the surface of the support plate body 2 which is the surface on the cutting plate 20 side when the support plate body 2 is attached to the die mold 10, and the positioning disk 6 described later is detachably fitted and supported. It is supposed to be. The illustrated disk connecting portion 5 is a plane that fits a little forcibly with the circular connecting hole opened at the center of the positioning disk 6 in correspondence with the positioning disk 6 being formed to have a donut shape. It is formed in the shape of a projection having a circular shape, and its height is substantially the same as the thickness of the positioning disk 6. When the positioning disk 6 is formed in a donut disk shape as shown in the figure, for example, a notch arranged in a cross shape, for example, is formed on the periphery of the connection hole that is slightly smaller than the outer diameter of the disk connection portion 5 to force It is better to fit them together.

  Although not shown in the drawings, the disk connecting portion 5 is formed so that the positioning disk 6 is formed in a circular depression shape along an outer shape that is, for example, a disk shape, and can be forcibly fitted into the disk. The depth of the depression is substantially the same as the thickness of the positioning disk 6. In any case, even if the positioning disk 6 is fitted and supported by the disk connecting portion 5 and the die mold 10 is directed toward the cutting plate 20, the positioning disk 6 itself is not dropped.

  As shown in FIG. 2 (a), the center position of the disk connecting portion 5 is based on the intersection with the ruled line blade 11 or the cutting blade 12, with a predetermined interval y from the position of the first edge a. This is set as an intersection that is a position separated by a predetermined distance x from the position of the second edge b. In other words, the center position of the disk connecting portion 5 is such that the support plate is arranged so as to intersect the angle α at which the ruled line blade 11 or the cutting blade 12 intersects at the intersecting part and the position of the ruled line blade 11 or the cutting blade 12. If the predetermined distances x and y from the support portion 3 arranged and formed on the edges (a, b) of the main body 2 are determined, the position is determined as an intersection position specified as only one place. This is because, in the surface plate 15 formed corresponding to the ruled line blade 11 and the cutting blade 12 arranged on the die 10, in the vicinity of the corresponding intersecting part with reference to the ruled line position and the cutting edge position, As shown in FIG. 2 (b), the positioning disk 6 is fitted on the face plate 15 at a predetermined interval x, y from the ruled line position or cutting edge position and an angle α at which the ruled line or cutting edge intersects the intersection. This means that the center position of the positioning hole 18 can be set.

  The predetermined intervals x and y are set to an equidistant position (x = y) from the center position of the support portion 3 particularly at their edges, and the crossing angle α is set to 90 degrees. As a result, the positions where the positioning holes 18 formed in the surface plate 15 described later are formed can be easily positioned.

  The positioning disk 6 has a circular outer shape and is formed of a plate material having substantially the same thickness as that of the face plate, and one of the side surfaces of the positioning disk 6 has a fine adsorptive property so as to adhere to the surface of the cutting plate 20. It is formed by covering the micro adsorbing board in which a large number of hole structures are arranged or the coated adhesive with a release paper 7 that can be peeled off. As shown in the figure, when fitted to the projecting disk linking part 5, a donut disk shape is formed, and when fitted to the recessed disk linking part 5, a disk shape is formed. The shape or disc shape is appropriately selected.

  Of course, this positioning disk 6 can also be made into a non-circular shape. When positioning with the positioning hole in the face plate, the positioning disk 6 is adapted so as to be adapted in a specific direction. One positioning hole 18 may be used.

  On the other hand, the surface plate 15 fixed to the surface of the cutting plate 20 facing the die mold 10 so as to cut and form the sheet material together with the die mold 10 has a position of the ruled line blade 11 to form a ruled line in the sheet material. The cutting edge 17 corresponding to the position of the cutting blade 12 is formed so as to cut along the outer shape so as to cut the ruled line groove 16 and the sheet material. Further, a positioning hole 18 is formed to be fitted to the positioning disk 6 when the surface plate 15 is positioned and fixed on the surface of the cutting plate 20. The surface plate 15 itself has a thickness of, for example, about 0.1 to 0.5 mm, and the back surface is adhered to the cutting plate 20 surface, and has a microstructured suction disk and an adhesive covered with a peelable release paper. Adhesive means such as an agent is provided. The material is a material having a reduced hardness difference from the sheet material, such as PP, PVC, PET, acrylic, Bakelite (registered trademark) or other plastic sheet material, or glass fiber material. The ruled groove 16, the cutting edge 17 and the like are usually NC processed by CAD.

  The positioning hole 18 is tightly fitted to the positioning disk 6 of the positioning support board 1 attached to the die 10 so that the ruled groove 16 and the cutting edge 17 are aligned with the ruled blade 11 and the cutting blade 12, respectively. Thus, the center position and the outer shape are matched. That is, it is formed at a predetermined position of the surface plate 15 corresponding to the position of the positioning disk 6 by the positioning support board 1 attached to the die mold 10 so as to be substantially the same as the outer shape of the positioning disk 6.

  As described above, the position of the disk connecting portion 5 of the positioning support board 1 is set to the predetermined interval x, y from the position of the ruled line blade 11 or the cutting blade 12 intersecting each other. Similarly, the positioning hole 18 is formed by opening an opening in substantially the same shape as the outer shape of the positioning disk 6 around the intersection position of the predetermined intervals x and y from the intersecting ruled line groove 16 or cutting edge 17 position. .

  Further, as described above, the attachment position of the positioning support board 1 with respect to the die mold 10 may be any part as long as the ruled line blade 11 or the cutting blade 12 intersects. At the time of creation, in the vicinity of the intersection where the ruled line groove 16 or the cutting edge 17 intersects, the intersection position of the predetermined intervals x and y from the ruled line groove 16 or the cutting edge 17 is measured using the intersection part as a base point, and the intersection position is the center. The positioning hole 18 may be formed by punching out with substantially the same circle as the outer shape of the positioning disk 6. In the die mold 10, the positioning support plate 1 is attached to the intersection of the ruled line blade 11 or the cutting blade 12 corresponding to the position of the ruled groove 16 or the cutting edge 17 in the vicinity of the positioning hole 18 formed in the face plate 15, The positioning disk 6 is mounted on the disk connecting portion 5 and the die 10 is moved in contact with the surface of the cutting plate 20 so that the positioning disk 6 serving as a mark on the surface of the cutting plate 20 is shifted according to the surface plate 15. it can.

  Next, an example of the use of this will be described. For example, when a sheet material constituting a box container or the like is punched and formed, the development outline of the box container, the ruled groove 16 corresponding to the ruled line, and the face plate 15 on which the cutting edge 17 is arranged are formed. A die mold 10 is formed in which the blade 11 and the cutting blade 12 are embedded in, for example, a plywood having a predetermined thickness. In forming the die mold 10 and the face plate 15, the face plate 15 has a predetermined distance from the support portion 3 in the positioning support plate 1 at, for example, at the two intersecting portions where the ruled groove 16 intersects each other. The positioning disk 6 is cut out with the diameter of the intersection point at the same interval as x and y as the center, and the positioning hole 18 is opened (see FIG. 2B). Further, in the die mold 10, the positioning support plate 1 is forcibly forced by the support portion 3 so as to straddle each of the ruled line blades 11 that intersect with each other corresponding to the intersecting portion where the positioning hole 18 is formed in the face plate 15. The positioning disk 6 is fitted and mounted on the disk connecting portion 5 and the release paper 7 is peeled off (see FIG. 4A).

  Next, the die mold 10 is set on a punching machine, and is lowered and brought into contact with the cutting plate 20 to shift the positioning disk 6 onto the cutting plate 20 (see FIG. 4B). The face plate 15 is fixed to the surface of the cutting plate 20 so that the positioning hole 18 is fitted to the positioning disk 6 thus transferred to the cutting plate 20 (see FIG. 4C).

  In this manner, the ruled line groove 16 of the face plate 15 is aligned with the ruled line blade 11 in the die mold 10 and the cutting edge 17 is similarly aligned with the cutting blade 12. A sheet member is inserted between the plate 20 and a sheet member S having a predetermined shape in which a ruled groove is formed is formed by punching (see FIG. 4D).

  When positioning the die mold 10 and the face plate 15 as shown in FIG. 1, the positioning support board 1 and the corresponding positioning holes 18 are usually arranged at two locations. More precise alignment is possible by having three or more alignment points.
