Description

  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 9A shown in FIGS. 17A and 17B is known for punching a film, a plate, or the like. In this punching die 9A, a punching blade 91 (a band-like blade in FIGS. 17A and 17B) is embedded in a board 92 made of plywood. In the punching die 9 </ b> A, a plurality of notches C are formed on the lower end side of the punching blade 91. Further, the board 92 is formed with a slit S penetrating between the front surface and the back surface, leaving a portion corresponding to the notch C. 17A and 17B, an elastic block 93 (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 91. With this elastic block 93, the punched product and the remaining residue can be ejected.
For example, a punching die 9B shown in FIG. 18 is also known for punching out films, plates, and the like. In this punching die 9B, a metal plate is cut out to create a punching blade. In FIG. 18, the elastic plate 94 (thickness is thicker than the height of the blade edge | tip T) is provided along the inner side and the outer side of the punching blade 91 (FIG. 18 cutting blade). With this elastic plate 94, the punched product and the remaining residue can be ejected.
The punching die 9B has a much higher punching accuracy than the punching die 9A described in FIGS. 17 (A) and 17 (B). However, a large die (for example, a die having a size of 1000 cm ² or more) becomes heavy and is not easy to process.

  The punching die 9A (FIGS. 17A and 17B) and the punching die 9B (FIG. 18) may be set on the lower surface plate 82 of the flat plate press 8 as shown in FIG. Although not shown, the punching dies 9A and 9B may be set on the upper surface plate 81. In this case, the film F wound up on the roll is sent out between the upper surface plate 81 and the lower surface plate 82 and punched out.

By the way, when the punching die 9A (FIGS. 17A and 17B) becomes unnecessary (when it is no longer used), the punching blade 91 is removed from the board 92, and this punching blade 91 is usually disposed of by metal disposal. It is processed as a thing.
Further, when the punching die 9B (FIG. 18) becomes unnecessary (when it is no longer used), the metal plate on which the punching blade 91 is formed is treated as metal waste.

  As described above, the conventional punching dies 9A and 9B cannot be reused (reused) and reused (recycled), which is uneconomical.

  In many cases, the punching die 9A (FIGS. 17A and 17B) is discarded (embedded in the ground or incinerated) without removing the elastic block 93 from the board 92. As a result, the die 9A that is no longer used may cause soil contamination and air pollution.

The punching die 9B shown in FIG. 18 has a much higher punching accuracy than the punching die 9A shown in FIGS. 17A and 17B, but a large punching die (for example, a punching die of 2500 cm ² or more). Is heavy and is not practical because it is not easy to process.
It is also assumed that a large die is composed of a plurality of modules and these are connected to complete the 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 to 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 punching die of the present invention is summarized as (1) and (2).
(1) A punching die in which a plurality of jigs with position adjusting functions for a punching blade are attached to a jig fixing panel, and the punching blade is supported by the jig.

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

  The cutting edge of the punching blade typically has a closed shape (loop), and usually the inside of the punched film is 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 cutting edge of the punching blade is a long straight line, this straight portion of the punching blade can be constituted by a strip-shaped blade or a thin cutting blade.
When the cutting edge of the punching blade is a curve, this curved portion of the punching blade can be constituted by a board embedded with a belt-like blade, and the cutting blade is formed by cutting the curved portion of the punching blade. It can be constituted by a metal plate such as a rectangle.
When the cutting edge has a complicated shape (when the shape of the cutting edge is stepped, zigzag, etc.), the complicated shape of the punching blade is made of plywood, synthetic resin, metal with a band-shaped blade embedded in it. It can be comprised with the board which consists of. Moreover, the complicated shape part of a punching blade can be comprised with metal plates, such as a rectangle in which the cutting blade was formed.

  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 cutting blade for forming the hole having the predetermined shape can be formed on a board in which a band-shaped blade is embedded. Further, the cutting blade for forming the hole having the predetermined shape can be formed on a metal plate such as a rectangle on which the 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. Further, the upper surface layer can be made of a metal plate such as aluminum or stainless steel, the other layer can be made of aluminum, stainless steel, plastic or the like, and the entire jig fixing panel can be constituted by a multilayer plate.

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. An inner pressing member and an outer pressing member are disposed between the inner jig frame 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).

  The fastening of the jig with the position adjusting function to the jig fixing panel is typically performed by a screw, a bolt 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.

(2) The punching die according to (1), wherein the jig fixing panel is threaded in a lattice point shape, and the jig with the position adjusting function is screwed onto the jig fixing panel with a screw. Punching die characterized by being combined.

The screws 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. 17A and 17B) or an elastic plate (FIG. 18) can be used as the spring-out member. 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.

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.
