Description

Die

The present invention relates to a punching die in which a jig with a position adjusting function for a punching blade is attached to a jig fixing panel, and the punching blade is supported by the jig, and many of the components can be reused even after being used. It relates to a die that can be cut.

For example, a punching die 19A shown in FIGS. 23A and 23B is known for punching a thin body such as a film, a nonwoven fabric, or a plate.
In this punching die 19A, a punching blade 191 (a band-like blade in FIGS. 23A and 23B) is embedded in a board 192 made of plywood.
In the punching die 19 </ b> A, a plurality of notches C are formed on the lower end side of the punching blade 191.
Further, the board 192 is formed with a slit S penetrating between the front surface and the back surface, leaving a portion corresponding to the notch C.
In FIGS. 23A and 23B, an elastic block 193 (having a height higher than the position of the cutting edge T) is provided along the inner periphery and the outer periphery of the punching blade 191.
With this elastic block 193, the punched product and the remaining residue can be ejected.
For example, a punching die 19B shown in FIG. 24 is also known for punching out films, plates, and the like.
In the punching die 19B, a metal plate is cut out to create a punching blade.
In FIG. 24, elastic plates 194 (thickness is thicker than the height of the cutting edge T) are provided along the inside and outside of the punching blade 191 (the cutting blade in FIG. 24).
With this elastic plate 194, the punched product and the remaining residue can be ejected.

The punching die 19A (FIGS. 23A and 23B) and the punching die 19B (FIG. 24) may be set on the lower surface plate 182 of the flat plate press 18 as shown in FIG.
Although not shown, the punching dies 19A and 19B may be set on the upper surface plate 181. In this case, the film F wound up on the roll is moved between the upper surface plate 181 and the lower surface plate 182. It is sent out in the middle and punched.

By the way, when the punching die 19A (FIGS. 23A and 23B) becomes unnecessary (when it is no longer used), the punching blade 191 is removed from the board 192, and this punching blade 91 is usually disposed of by metal disposal. It is processed as a thing.
In addition, when the punching die 19B (FIG. 24) becomes unnecessary (when it is no longer used), the metal plate on which the punching blade 191 is formed is treated as metal waste.

As described above, the conventional punching dies 19A and 19B cannot be reused or reused (recycled), which is uneconomical.

In many cases, with respect to the punching die 19A (FIGS. 23A and 23B), the elastic block 193 is not removed from the board 192 but is discarded (embedded in the ground or incinerated).
As a result, the die 19A that is no longer used may cause soil contamination and air pollution.

Note that the punching die 19B shown in FIG. 24 has a much higher punching accuracy than the punching die 19A shown in FIGS. 23A and 23B, but a large punching die (for example, a punching die of 1,000 cm ² or more). The mold) is not practical because it is heavy and is not easy to process.
It is also assumed that a large punching die is composed of a plurality of machined punching blade modules and these are connected to complete the punching die. However, it is not easy to align the blade edge of each module.
For this reason, conventionally, a large punching die has not been configured from a plurality of cut-out modules.

It is an object of the present invention to provide a new structure die that allows reuse of most of the components even when used.
In this connection, the object of the present invention is also to reduce or reduce deforestation and contribute to CO ₂ reduction by avoiding the use of plywood as much as possible.
Another object of the present invention is to provide a lightweight punching die constituted by a punching blade module created by machining.

The outline of the punching die of the present invention is (1) to (6).

(6)
Inside the punching blade and / or outside, there is provided a jumping member comprising a jumping plate for jumping out the punched product and a coil spring for biasing the jumping plate toward the other surface plate surface. The die according to (1), characterized in that

In the present invention, the punching blade may be a belt-like blade (also referred to as a so-called Thomson blade) or a shaving blade. Further, the punching blade may be a combination of a belt-like blade and a cutting blade.

The outline of the cutting edge of the punching blade in a plan view typically has a closed shape (loop), and the inside of the punched film is usually a product film or the like.
Another blade for forming a predetermined shape hole (round hole, square hole, etc.) in the product film or the like may be formed inside the loop.

When the plan view of the cutting edge of the punching blade is a straight line or a curved line, it is preferable that the straight or curved portion of the punching blade is constituted by a strip-shaped blade.
When the plan view of the cutting edge is a complicated shape (when the shape of the cutting edge is a stepped shape, a zigzag shape, etc.), it is preferable that the complicated shape portion of the punching blade is constituted by a cutting blade. It is also preferable that the portion is constituted by a board made of plywood, synthetic resin, or metal in which a cutting blade or a band blade is embedded.

When other blades for forming a predetermined shape hole (round hole, square hole, etc.) are formed inside the loop-shaped cutting edge of the punching blade, a predetermined shape hole (round hole, square hole, etc.) ) Can be constituted by a machined blade.
The shaving blade for forming the hole having the predetermined shape can be constituted by a board in which a belt-like blade is embedded.
Further, the shaving blade for forming the hole having the predetermined shape can be constituted by a metal plate such as a rectangle on which a blade cut out in a loop shape is formed.

The jig fixing panel can be composed of a single member such as aluminum or stainless steel.
In addition, the jig fixing panel can be composed of a plurality of members in multiple layers. For example, the surface layer may be a metal plate with high hardness such as stainless steel or duralumin, and the other layer may be a metal plate with low hardness of aluminum or plastic.

Wood, synthetic resin, ceramic, glass, metal, etc. can be used for the jig with position adjusting function.
The jig with a position adjusting function may be a structure that holds the punching blade.
The jig with a position adjusting function can be constituted by an inner jig frame, an outer jig frame, an inner pressing member, and an outer pressing member.
The inner pressing member is disposed between the inner jig frame and the punching blade, and the outer pressing member is disposed between the punching blade and the outer jig frame.

The punching blade is sandwiched between the inner pressing member and the outer pressing member. The jig frames (inner jig frame and outer jig frame) may be configured separately (separate members) or may be configured integrally.
When the inner jig frame and the outer jig frame are configured separately, the distance between the inner jig frame and the outer jig frame can be adjusted. For example, the distance between the inner jig frame and the outer jig frame may be a pitch of two lattice points, and the punching blade may be sandwiched between the inner pressing member and the outer pressing member, or the distance between the inner jig frame and the outer jig frame may be The punching blade may be sandwiched between the inner pressing member and the outer pressing member with an N lattice point pitch (N = 3, 4, 5).

締結 Fastening of a jig with a position adjustment function to a jig fixing panel is typically performed with screws, bolts, or the like. In the punching die of the present invention, a jig with a position adjusting function can be attached to a jig fixing panel, and a punching blade can be held by the jig with a position adjusting function.

The screw holes can be formed directly at the lattice points of the jig fixing panel. Further, a member having an internal thread can be embedded in a lattice point of the jig fixing panel.
Various patterns can be adopted as the pattern of screws formed on the jig fixing panel, and typically a square lattice or a triangular lattice may be used.

In the present invention, a conventional elastic block (FIGS. 23A and 23B) and an elastic plate (FIG. 24) can be used as the spring-out member, and a spring-out member using a metal spring (FIG. 17). (See FIG. 22).
The jumping member using the elastic block or the elastic plate cannot be reused in many cases, but the jumping member using the metal spring can be reused.

In the present invention, it is not necessary that all the jigs are jigs with a position adjusting function. In other words, a jig having no position adjusting function can be used for a part of the punching blade. For example, when the plan view outline of the punching blade is rectangular, it is not necessary to adjust the position of the two adjacent sides, and it is only necessary to adjust the position of the other two sides.

The jig fixing panel has a screw for attaching a jig with a position adjustment function (or a jig with a position adjustment function, for example, a jig without a position adjustment function when the punching blade has a rectangular plan view outline). A hole can be formed in advance. Further, this screw hole may be formed when the punching blade is aligned.

A jig hole without a position adjusting function described above can also have a screw hole as a long hole or a cross-shaped hole.
By making the screw hole a long hole or a cross-shaped hole, the degree of freedom of arrangement of a jig with a position adjustment function (or a jig without the position adjustment function described above) can be increased.
The jig with the position adjusting function can be adjusted in the position of the punching blade while being fixed to the jig fixing panel.
Further, the position adjustment function jig itself can be finely moved with respect to the jig fixing panel by an eccentric screw to adjust the position.

Even when the die of the present invention is used, most of the components are reused. Therefore, waste can be drastically reduced and effective use of resources can be achieved.
In the punching die of the present invention, a board such as a plywood can be avoided, and even if it is used, it is very small (for example, 1/10 or less of the conventional one).
Even if the cutting blade is modularized and incorporated in the punching die of the present invention, the weight does not increase.
