Description

Cutting device

The present invention relates to a die cutting device for forming a workpiece cut piece of a certain shape by die cutting from a sheet-like workpiece.

The present application claims priority based on Japanese Patent Application No. 2014-190793, filed on Sep. 19, 2014, the entire disclosure of which is incorporated herein.

As one of the methods of forming a workpiece cut piece having a certain shape from a sheet-like workpiece, a method of performing die cutting using a cutting die is known.

As for a die-cutting die for, for example, a film having a thin wall thickness as a die-shaped workpiece, a die having the following configuration has been proposed: an inner side and an outer side of the cutter in the surface of the base plate An elastic material such as a sponge or urethane or rubber sheet having a height that can hide the tip of the cutter is provided. Further, in the case of using the cutting die, there has been proposed a technique of placing a sheet-like workpiece on the upper side of the elastic material and placing the blade tip on the upper side of the sheet-like workpiece for abutting the blade edge of the cutter After forming this state, the interposer is pressed by a pressing roller (for example, refer to Patent Document 1).

However, in recent years, one of the manufacturing methods for a product having a three-dimensional shape made of a fiber-reinforced resin such as CFRP or GFRP has been developed by the following method: by using a die-cutting die-cutting method A sheet-like workpiece formed by impregnating fibers of a resin to form workpiece cut pieces having slightly different outer shapes, and the workpiece cut pieces are laminated into a plurality of layers in a predetermined order and arrangement, and then integrated to form The desired three-dimensional shape.

In such a manufacturing method, since the error of the shape (outer shape) of the workpiece cut piece formed by die cutting affects the finally formed three-dimensional shape, in the die cutting of the workpiece cut piece by the cutter, Being required to be precise.

However, as shown in Patent Document 1, when the sheet-like workpiece is cut, even if the sheet-like workpiece is pressed by the pressing roller through the interposing plate, it is not compressed to the elasticity disposed inside and outside the cutter. When the material is at a height below the position of the cutting edge of the cutter, the sheet-like workpiece does not come into contact with the cutter. Therefore, when the sheet-like workpiece is cut, the sheet-like workpiece does not easily enter the inside of the cutter, and the positional displacement of the sheet-like workpiece with respect to the cutter is liable to occur.

Fig. 3 is a schematic view showing a sheet-like workpiece that is pressed at the time of cutting, Fig. 4 is a schematic view showing a pin provided on the die body, and Fig. 5 is a view showing a height dimension of the elastic member inside the blade.

The cutting device of the present invention is shown by the symbol 1 In the 1A, 1B, 1C, and 2nd drawings, the die body 2 and the cover 3 disposed above the die body 2 are formed.

The die body 2 is provided with: a base plate 4; a cutter 5 provided on the base plate 4 and protruding from the surface; a blade outer elastic member 6, an outer side region of the cutter 5 provided in the surface of the base plate 4; and a blade inner side The elastic member 7 is disposed in an inner region of the cutter 5 in the surface of the base plate 4.

The cutter 5 is continuously formed into a ring shape along the shape (contour) of the workpiece cut piece X to be formed. Further, the cutter 5 is such that its tip 5a protrudes from the surface of the base plate 4 by a size larger than the thickness of the sheet-like workpiece W.

In addition, the form of the cutter 5 can be any one of the Thomson blade, the engraving knife, and the etching knife used in the prior art, and the Thomson knife, the engraving knife, and the etching can be combined in each part. Two or three of the knives.

As shown in Fig. 2, in the present embodiment, four cutters 5 having a substantially parallelogram shape are provided on the surface of the base plate 4.

Here, the cutting device 1 of the present invention is used in the pressing of the sheet-like workpiece W to be described later, and the workpiece cutting piece X is formed as shown in FIG. 1A, FIG. 1B, and FIG. 1C. The illustrated roller press is used as a pressing mechanism. Further, the cutting device 1 of the present invention is configured such that the pressing roller of the roller presser relatively moves in the direction along the long side of the rectangular base plate 4 as indicated by an arrow D in FIG. The pressing roller presses. Therefore, the cutting device 1 of the present invention is from the foregoing The region where the pressing roller receives the pressing load is a linear region extending along the axial direction of the pressing roller, that is, a linear region extending in a direction perpendicular to the direction of the arrow D. Therefore, the cutting device 1 of the present invention is a region in which a linear pressing load is applied in a direction perpendicular to the arrow D direction with respect to the pressing roller in the direction of the arrow D, and the direction and the arrow are directed. The direction of the opposite direction of D moves in sequence. Thereby, the cutting device 1 of the present invention is sequentially pressed in the direction along the long side of the rectangular base plate 4 to perform pressing over the entire surface.

Here, as described above, in the cutting device 1 of the present invention, when the pressing roller is pressed, a region in which a linear pressing load is applied in a direction perpendicular to the direction of the arrow D is directed to the arrow. The direction of the opposite direction of D moves in sequence. Therefore, for example, when a portion where the cutter 5 is continuous is arranged in a direction perpendicular to the direction of the arrow D, a concentration against the pressing load is concentrated at the portion. Therefore, the arrangement (nesting) of the four cutters 5 in the surface of the base plate 4 is preferably set to a portion of each of the cutters 5 that is linearly extended, and is disposed at a deviation from the arrow D. The direction of the direction of the direction of the right angle. In the present invention, in order to disperse the resistance against the pressing load in the portion in which the cutter 5 is disposed, the portion in which each of the cutters 5 is linearly extended is disposed in a direction perpendicular to the direction of the arrow D. The direction. As a result, in the cutting device 1 of the present invention, it is possible to suppress the rapid application of a large force when the pressing roller is pressed, so that the conveyance in the roller press can be stabilized.

Also, outside the respective cutters 5 in the surface of the base plate 4 The side region is provided with a remaining sheet cutting edge 8 for performing die cutting of the workpiece cutting piece X from the sheet-like workpiece W, for example, as shown in Fig. 2 . The remaining remaining sheet Y is cut into a size that is easy to handle. The remaining sheet cutting blade 8 has the same projection height from the surface of the base plate 4 to the blade edge as the respective cutters 5.

Further, as shown in Fig. 2, the remaining sheet cutting edge 8 is set to extend in a direction shifted by a certain angle from the direction perpendicular to the arrow D. Moreover, when a plurality of remaining sheet cutting blades 8 are provided, the remaining sheet cutting blades 8 are arranged to be shifted from each other in the direction of the arrow D. The reason why the remaining sheet cutting blade 8 is configured as described above is that, in the same manner as the arrangement of the respective cutters 5 described above, a portion for arranging a portion where the remaining sheet cutting edge 8 is continuous or a plurality of portions is disposed. The remaining pieces cut the portion of the blade 8 to disperse the resistance to the pressing load. Therefore, even in the cutting device 1 of the present invention, even in the cutting device 1 of the present invention, it is possible to suppress the rapid application of a large force when the pressing roller is pressed. The handling in the aforementioned roller press is stabilized.

A blade outer elastic member 6 having a certain height dimension is provided on a portion of the outer surface of each of the cutters 5 on the surface of the base plate 4 so as not to interfere with the remaining sheet cutting edge 8. The blade outer elastic member 6 is formed of a material such as sponge, urethane or rubber, and is elastically deformable in the vertical direction.

In addition, in this specification, the height is simply the amount which protrudes from the surface of the base board 4, and does not contain the directionality of the up-and-down.

The height dimension of the outer elastic member 6 of the blade is set It is the same size as the protruding height of each of the cutters 5 from the surface of the base plate 4 to the cutting edge 5a, or a size larger than the size.

The inner side of each of the cutters 5 on the surface of the base plate 4 is provided with a blade inner side having a height smaller than the projection height of the cutter 5 from the surface of the base plate 4 to the cutting edge 5a of the cutter 5. Elastic member 7. Thereby, the height difference between the blade edge 5a of the cutter 5 and the surface of the blade inner elastic member 7 is formed inside the blade edge 5a of the cutter 5.

The blade inner elastic member 7 is formed of a material such as sponge, urethane or rubber, and is elastically deformable in the vertical direction as in the blade outer elastic member 6. Further, the material of the blade inner elastic member 7 may be the same material as the material of the blade outer elastic member 6, or one of different materials.

As shown in Fig. 5, the height dimension p of the blade inner elastic member 7 is preferably set to q by the height of each of the cutters 5 from the surface of the base plate 4 to the blade edge 5a, and the thickness of the sheet-like workpiece W is set. When the size of the blade-shaped workpiece W to be described later is cut by the respective cutters 5, the amount of the blade edge 5a of each of the cutters 5 is set to s, and the amount is set to s. The value calculated by the formula.

p=q-(s+r)

According to this setting, since the deformation of the blade inner elastic member 7 can be prevented when the sheet-like workpiece W is cut, when the sheet-like workpiece W is cut and the workpiece cutting piece X is formed, the sheet-like workpiece W can be prevented from accompanying the inside of the blade. The possibility that the elastic member 7 is deformed in the up-down direction and the position is shifted.

Further, as shown in FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 2, the region of the upper surface of the blade outer elastic member 6 on which the sheet-like workpiece W is placed, and the blade inner elastic member 7 are provided. On the surface, for example, a fluororesin sheet 9 made of tetrafluoroethylene or another fluororesin is integrally provided as a sheet having a material having a tensile rigidity higher than that of the respective materials and having a smaller friction coefficient than the respective materials. In the cutting device 1 of the present invention, as described above, when pressing with a pressing roller, the region in which the linear pressing load is applied in a direction perpendicular to the direction of the arrow D is directed to the arrow D direction. The opposite direction moves in sequence. Therefore, the blade outer elastic member 6 and the blade inner elastic member 7 are simultaneously deformed in a partially concave manner by receiving a linear portion of the pressing load in a direction perpendicular to the direction of the arrow D from above. The concave portion is moved in a direction opposite to the direction of the arrow D. At this time, since the fluororesin sheet 9 having a higher tensile rigidity is integrally provided on the upper surface of the blade outer elastic member 6 and the blade inner elastic member 7, the blade outer elastic member 6 and the blade inner elastic member are integrally provided. 7 is a single case in which the deformation that can withstand the pressing load and the partial depression is averaged in the direction of the arrow D. Therefore, local deformation of the sheet-like workpiece W placed on the outer surface of the blade outer elastic member 6 and the blade inner elastic member 7 can be suppressed. Further, when the blade outer elastic member 6 and the blade inner elastic member 7 are deformed as described above, the fluororesin sheet 9 and the sheet-like workpiece W can be slid to prevent wrinkles from occurring in the sheet-like workpiece W.

In addition, in the case of forming a structure in which the fluororesin sheet 9 is integrally provided on the upper surface of the blade outer elastic member 6, as long as The height dimension of the blade outer elastic member 6 after the thickness of the fluororesin sheet 9 is increased to the same size as or higher than the protrusion height of the cutter 5 from the surface of the base plate 4 to the blade edge 5a of the cutter 5. The larger size is enough.

In the case where the fluororesin sheet 9 is integrally formed on the upper surface of the blade inner elastic member 7, the height dimension of the blade inner elastic member 7 after the thickness of the fluororesin sheet 9 is added, The protruding height of the cutter 5 from the surface of the base plate 4 to the cutting edge 5a of the cutter 5 may be lower. In this case, the value of the preferred height dimension p of the blade inner elastic member 7 shown in Fig. 5 is as shown by the chain line of Fig. 5, as long as the thickness of the fluororesin sheet 9 is set. The height of the elastic member 7 on the inner side of the blade may be.

Further, as shown in FIG. 1A, FIG. 1B, and FIG. 1C, the outer surface of the blade outer elastic member 6 is a plurality of portions near the outer side of the region on which the sheet workpiece W is placed. A pin 10 that is used to prevent the offset of the cover 3 is protruded from above.

On the other hand, in the lid body 3, as shown in FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 4, the portion corresponding to the arrangement of the pins 10 of the die body 2 is laid in the vertical direction. There are pin insertion holes 11 for inserting the respective pins 10 from below.

As shown in Fig. 2, each of the pins 10 is preferably disposed so as to be arranged along three sides of the four sides of the rectangular sheet-like workpiece W. This is because when the sheet-like workpiece W is mounted on the upper side of the blade outer elastic member 6 of the die body 2, the sheet-like workpiece W can be prevented from being provided. The side of the pin 10 is disposed along the upper surface of the blade outer elastic member 6, and the mounting work of the sheet-like workpiece W on the die body 2 is facilitated. Further, the blade outer elastic member 6 is provided with a hole or a slit for inserting a pin into a portion corresponding to the arrangement of the respective pins 10.

Further, the pin 10 on the base plate 4 and the pin insertion hole 11 on the side of the lid body 3 corresponding to the pin 10 are arranged in a plurality of rows in the direction of the arrow D at a certain interval. In the cutting device 1 of the present invention, as described above, when pressed by the pressing roller, the region in which the linear pressing load is applied in a direction perpendicular to the direction of the arrow D is directed to the aforementioned The arrow D moves in the opposite direction. Therefore, even if the lid body 3 is deformed so as to be bent downward so as to receive the pressing load, any one of the pin 10 and the pin insertion hole 11 arranged in the direction of the arrow D can be engaged, and the lid body 3 can be prevented. Offset.

Further, as shown in Fig. 4, the pin 10 is composed of the following members: a cylindrical pin portion 12 extending in the up-and-down direction; and a conical ladder-shaped pin head 13 provided on the upper end side of the pin portion 12. .

The pin portion 12 is set to have a size corresponding to the height from the surface of the base plate 4 to the surface of the fluororesin sheet 9 on the blade outer elastic member 6 and the thickness of the sheet-like workpiece W. value. Thereby, when the sheet-like workpiece W is attached to the upper side of the blade outer elastic member 6 by the die body 2, the end surface of the sheet-like workpiece W can be abutted against the pin portion of the pin 10 corresponding thereto. Configured on the side of the 12th. Therefore, the sheet-like workpiece W attached to the die body 2 suppresses the movement of the respective pins 10 in the direction in which they are arranged.

Further, in this state, each of the pins 10 can hold the edge of the sheet-like workpiece W between the blade outer side elastic member 6 and the step outer portion 14 between the pin portion 12 and the pin head portion 13. Thereby, it is possible to prevent the floating of the edge of the sheet-like workpiece W attached to the die body 2.

When the pin head portion 13 is formed in a conical trapezoidal shape, it is easy to mount the lid body 3 on the upper side of the sheet-like workpiece W mounted on the die body 2 by the inclined surface on the outer circumference of the pin head portion 2. The correspondingly disposed pins 10 are inserted into the respective pin insertion holes 11 of the cover 3.

The size of the pin 10 protruding from the surface of the base plate 4 and the thickness of the lid body 3 are set so as to cut the sheet-like workpiece W by the respective cutters 5, and the lid body 3 is lowered to the respective cutters 5 When the blade edge 5a penetrates the position of the lower surface of the lid body 3, the top of the pin 10 does not protrude toward the upper side of the lid body 3.

According to the configuration in which the die body 2 includes the pin 10 and the lid body 3 includes the pin insertion hole 11, the cover body 3 can be restrained in the horizontal direction of the die body 2 with the pin 10 inserted into the pin insertion hole 11. Relative position. Thereby, the position of the sheet-like workpiece W or the workpiece cut piece X can be excluded, and the position may be shifted in the horizontal direction in accordance with the lid body 3 that is in contact with the upper surface side.

Further, the blade inner elastic member 7 disposed inside each of the cutters 5, and the fluororesin sheet 9 provided on the upper surface of the blade inner elastic member 7, and the base plate 4 are formed inside the respective blades 5. The portion to be provided is provided with an adsorption hole 15 penetrating in the vertical direction. Thereby, in the die body 2, by using the connection to the lower end side of the adsorption hole 15, The suction device shown in the drawing is sucked by the suction hole 15, so that the workpiece cut piece X cut from the sheet-like workpiece W by the cutter 5 can be sucked and held on the upper side of the blade inner elastic member 7. Even in the outer side of the cutter 5 and in the portion where the remaining sheet Y is disposed, the suction hole 15 is inserted in the vertical direction, and is disposed on the outer blade elastic member 6 and the outer elastic member 6 on the outer side of the blade. The fluororesin sheet 9 on the upper surface and the base sheet 4. Thereby, even in the die body 2, the workpiece cut piece X and the cut piece remaining piece Y can be sucked and held by the suction through the suction hole 15 on the upper side of the blade outer elastic member 6.

In the case where the cutting device 1 of the present invention having the above configuration is used, the cover 3 is placed at a position away from the die body 2, or the cover 3 is moved so as not to be caught in the die body 2. In the state above the position, the sheet-like workpiece W is attached to the upper surface of the blade outer elastic member 6. At this time, the corresponding end faces of the sheet-like workpieces W are placed against the pin shaft portions 12 of the respective pins 10.

Next, as shown in FIG. 1A, the lid body 3 is attached to the upper side of the sheet-like workpiece W set to the die body 2. As a result, the sheet-like workpiece W is attached to the cutting device 1 of the present invention.

Then, the cutting device 1 of the present invention is relatively moved in the direction of the arrow D shown in FIG. 2 with respect to the pressing roller of the roller press (not shown), and the two upper and lower rollers are pressed by the pressing roller. The die body 2 and the cover 3 are pressed side or one side.

As a result, the region that receives the pressing load by the pressing roller moves in a direction opposite to the direction of the arrow D in the second drawing. The area subjected to the pressing load is as shown in Fig. 1B, so that the cover body 3 can be lowered to the position where the cutting edge body 2 of the cutter 5 is deeper than the cutting edge 5a of each of the cutters 5 to the lower surface of the cover body 3. The sheet-like workpiece W pushed down by the lid body 3 is cut by the depth of the blade edge 5a of each of the cutters 5 in order. At this time, when the sheet-like workpiece W positioned on the upper surface of the cutter 5 receives the pressing load applied by the pressing roller, as shown in FIG. 3, it is pushed downward and enters the cutter 5. The inside is easy to be in contact with the blade edge 5a of the cutter 5. When the blade edge 5a of the blade 5 is deep, the portion where the blade edge 5a penetrates is restrained by the cutter 5 from the relative displacement of the blade 5. Therefore, the sheet-like workpiece W can be prevented from being displaced from the cutter 5 during the process of being sequentially cut by the pressing load applied by the pressing roller. As described above, when the sheet-like workpiece W is cut by the cutter 5, the die-cut piece X that has been die-cut can be formed inside each of the cutters 5. The workpiece cut piece X is received by the blade inner elastic member 7 inside the respective cutters 5.

At this time, the remaining sheet Y is formed on the outer side of each of the cutters 5 from the sheet-like workpiece W. The remaining sheet Y is cut into a size that is easy to handle by the remaining sheet cutting blade 8.

In the cutting device 1 of the present invention, in this state, the suction holes 15 are sucked by the suction means, and the workpiece cut piece X is respectively attracted to the upper surface of the elastic member 7 on the inside of the blade, and the remaining piece is made. Y is adsorbed on the upper surface of the elastic member 6 on the outer side of the blade.

In addition, in the first drawing, the lid body 3 is pushed down as a whole for convenience of illustration, but actually, the pressing load applied by the pressing roller in the lid body 3 is applied. Area is Since the direction is reversed in the direction opposite to the direction of the arrow D (see FIG. 2), the lid body 3 is surely pressed to the position where the blade edge 5a of the cutter 5 penetrates the position of the lid body 3, and also faces the arrow D. Move in the opposite direction. Therefore, since the cutting of the sheet-like workpiece W by each of the cutters 5 is actually performed in the direction opposite to the direction of the arrow D, the adsorption of the workpiece cut piece X by the above-described adsorption holes 15 is performed. The adsorption by the remaining sheet Y is sequentially performed at the time point when the workpiece cut piece X and the remaining piece Y are formed.

After that, when the pressing of the cutting device 1 of the present invention is completed by the pressing roller, the lid body 3 is restored to the initial shape by the state in which the blade outer elastic member 6 is compressed in the vertical direction. As shown in Fig. 1C, it is pushed up to the initial position above the die body 2.

At this time, since the height dimension of the blade inner elastic member 7 is set to be lower than the projection height of each of the cutters 5 from the surface of the base plate 4 to the blade edge 5a, the sheet-like workpiece W is Before the cutting, the sheet-like workpiece W is pressed into the inside of the cutter 5, whereby the positional deviation of the sheet-like workpiece W at the time of cutting can be prevented. After the sheet-like workpiece W is cut, the workpiece cut piece X is held inside the cutter 5. On the other hand, the remaining sheet Y is moved to a position higher than the blade edge 5a of each of the cutters 5 as the blade outer elastic member 6 is restored to the initial shape.

Further, at this time, as long as the workpiece cut piece X is sucked to the upper surface of the blade inner elastic member 7 by the suction of the suction hole 15, the cover body 3 is lifted by the blade outer elastic member 6 When pushed, it is possible to more reliably prevent the workpiece cutting piece X from being electrostatically adsorbed, or vacuumed. Adsorption follows the movement of the cover 3.

Then, the workpiece cut piece X is in a state where the lid body 3 is disposed at a position away from the die body 2 or the lid body 3 is moved to a position where it does not get caught above the die body 2, by A picking device (not shown) is picked up from the inside of each cutter 5. Further, the remaining sheet Y is removed from the upper side of the blade outer elastic member 6 by using another pick-up device (not shown).

At this time, as long as the removal of the remaining sheet Y is performed earlier than the pickup of the workpiece cut piece X, even if the upper side of the blade outer elastic member 6 has been displaced in the position of the remaining sheet Y, the remaining sheet Y is not interfered. The picking of the workpiece cut piece X can be performed.

As described above, according to the cutting device 1 of the present invention, since the position of the upper surface of the blade inner elastic member 7 provided on the inner side of the cutter 5 is lower than the height of the blade edge 5a of the cutter 5, as shown in Fig. 3 It is to be noted that the sheet-like workpiece W can enter the inside of the cutter 5 in a concave shape and can be received by the blade inner elastic member 7. In this state, since the sheet-like workpiece W is in contact with the corresponding cutter 5, it is possible to prevent the position of the sheet-like workpiece W from being displaced with respect to the corresponding cutter 5 when the sheet-like workpiece W is cut.

Further, in the cutting device 1 of the present invention, the workpiece cut piece X formed by cutting the sheet-like workpiece W is held inside the cutter 5, and in this state, the outer peripheral end of the workpiece cut piece X is The corresponding cutters 5 are connected. Therefore, since the position of the workpiece cutting piece X is restrained by the cutter 5, in the cutting device 1 of the present invention, the sheet X can be cut for the formed workpiece to prevent the position of the corresponding cutter 5 from being biased. shift.

The cutting device 1 of the present invention is configured such that the cutting device 1 of the present invention is reversed in the upper and lower portions as a second embodiment, and is pressed by a pressing roller, and can be obtained in the same manner as in the above embodiment. The sheet-like workpiece W is prevented from being displaced, and is cut and die-cut.

That is, in this embodiment, the cutting device 1 of the present invention shown in Fig. 1A, Fig. 1B, and Fig. 1C is reversed in a complete set, and is pressed by a roller press (not shown). The cutting main body 2 and the lid body 3 are pressed from both sides or one side in the up-and-down direction, and in the same manner as described above, the region that receives the pressing load applied by the pressing roller is sequentially moved while the cutter is moved. 5 penetrates into the sheet-like workpiece W and cuts it.

At this time, the sheet-like workpiece W located on the lower side of the downward cutting blade 5 is pressed by the cover 3 by receiving the movement of the pressing load applied by the pressing roller. The sheet-like workpiece W in the portion inside the cutter 5 is sequentially cut in a state of being pushed into the inside of the cutter 5.

In this case, when the sheet-like workpiece W receives the pressing load applied by the pressing roller from below, it enters the inside of the cutter 5 and is easily brought into contact with the cutting edge 5a of the cutter 5.

Thereby, the sheet-like workpiece W is cut by the cutting blade 5 without being displaced by the cutting and cutting. At the same time, the remaining sheet Y is cut by the remaining sheet cutting edge 8.

Thus, when the cutting die body 2 is pressed against the sheet-like workpiece W in an upward position with respect to the sheet-like workpiece W, the die cutting device 1 of the present invention is reversed again, and as shown in FIG. 1A, 1B map, As shown in FIG. 1C, the sheet-like member W and the lid body 3 are positioned above the die body 2.

The subsequent operation is the same as that of the first embodiment shown in Figs. 1A to 5 .

Further, the present invention is not limited to the above-described respective embodiments, and the height dimension of the blade inner elastic member 7 can be set to be smaller than the protruding height of the cutter 5 from the surface of the base plate 4 to the blade edge 5a. Further, by causing the sheet-like workpiece W to enter the inside of the cutter 5 by the step of the blade inner elastic member 7 and the step edge 5a of the cutter 5, the height dimension of the blade inner elastic member 7 can be appropriately changed.

The shape, number, and arrangement of the cutters 5 provided in the die body 2 may be set to any shape, number, and arrangement other than the drawings. Further, the shape, arrangement, and number of the remaining sheet cutting blades 8 can be freely set in accordance with the shape, number, and arrangement of the cutter 5.

The pin 10 provided in the cutter body 2 may be formed in a cylindrical shape from the upper end to the lower end, instead of the pin head 13 having a conical ladder shape on the upper side of the pin portion 12 shown in Fig. 4 . Composition. Even with this configuration, the following effects can be obtained: the effect of preventing the relative displacement of the cover 3 relative to the die body 2 in the horizontal direction; and by abutting against the sheet-like workpiece W mounted on the die body 2. The end face prevents the positional displacement of the sheet-like workpiece W.

Further, in the case where the pin 10 provided in the die body 2 is only for the purpose of preventing the displacement of the die body 2 and the cover 3, it may be disposed not to be placed on the cut. Sheet-like work on the mold body 2 Any position where W interferes.

Further, the die cutting device 1 of the present invention can also use a pressing mechanism in the form of a base plate 4 and a cover 3 which are uniformly pressed over the entire surface and which is used for cutting from the sheet-like workpiece W. A pressing mechanism in which the pressing load of the workpiece cutting piece X functions is replaced by a roller press. In this case, the number of pins 10 provided in the die body 2 can also be reduced.

Further, it is a matter of course that various modifications can be made without departing from the spirit and scope of the invention.
