Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a product takeout die for a plate material processing machine.

(Prior Art) Conventionally, in a plate material processing machine such as a punching press, the product is taken out by a chute provided in the press. As shown in FIG. 4, an outline of the structure of the punching press is that an upper frame 3 is integrally provided above the base 1 with the base 1, and the base 1 and the upper frame 3 each have a disc shape. The lower turret 5 and the upper turret 7 are oppositely rotatably mounted. A plurality of dies 9 are concentrically arranged and mounted on the lower turret 5,
The upper turret 7 has a plurality of punches 11 corresponding to the die 9.
Is attached. A striker 13 for pressing the punch 11 is mounted at a fixed position on the upper frame 3 so as to be able to move up and down.

The base 1 is equipped with an NC-controlled work moving / positioning device that moves and positions the work W in the front-rear and left-right directions. This work moving / positioning device includes a first guide bar 15 provided before and after the drawing, a slide body 17 sliding along the first guide bar 15,
The second guide bar 19, which is supported by the sliding body 17,
The work holding device 21 is slidably supported along the work holding device 21 and an NC control device (not shown).

Further, a receiving device 25 for receiving a product separated from the work W or a waste material is mounted on the base 1 at a position close to the lower turret 5. In this receiving device 25,
There is a shoot 27. The chute 27 supports the work W horizontally when cutting off a product or a waste material from the work W, inclines after cutting off and drops these.

FIG. 5 is an enlarged view of the receiving device 25. As shown,
The chute 27 is located in the notch 29 provided in the table 2, and during punching processing, at the same height as the table 23, the chute 27 supports the work and the part which becomes a product or a scrap material is cut off. And tilt like 27 '.

The chute 27 is fixed to the rotating shaft 31, and the rotating shaft 31
When the drive device 33 rotates, the chute 27 also rotates,
Horizontal or tilt. On the lower right side of the chute 27, a cylindrical receiving guide 35 provided with a notch for receiving a product or waste material is provided.

When the product is cut off from the work W in which a large number of small-sized semi-finished products are taken from the large-sized plate material as shown in FIG. 6 by this punching press, the work is held and fixed by the work holding device 21, and the work moving positioning The joint portion 37 of the small semi-finished product of the work is positioned at the processing position by the device, and the joint portion is cut by the punching punch 11 and the die 9.
The punched product is collected along a tilted chute 27, dropped along the receiving guide 35 and stored in a product container (not shown).

(Problems to be solved by the invention) As described above, products processed by a punching press or the like are generally collected in a product container by a chute, but products exceeding the width of the chute or products having a complicated shape. Has a problem that it interferes with the remaining material and is hard to drop, and when the product is too small, it has a problem that even if the chute is tilted, it is supported by the die and does not drop to the chute side.

This invention was devised with such points in mind.By using a chute without dropping a product, the product is dropped into the mold for final cutting, which ensures reliable product removal and relatively fast sheet metal processing. The purpose of the present invention is to provide a die for taking out the product of the machine.

[Structure of the Invention] (Means for Solving the Problem) In view of the conventional problems as described above, the present invention provides a die including a punch and a die, in which the die also includes a center of the die. A product dropping hole is provided, and a cutting blade portion for cutting and separating a work and a product is provided at a position close to the product dropping hole at an eccentric position of the die, and the punch has a cutting blade of the die. A cutting blade portion corresponding to each portion is provided.

(Example) Next, the Example of this invention is described based on drawing. FIG. 1 is an explanatory view of a product taking out die of the present invention, which comprises a punch 39 and a die 41. Punch 39
A protruding cutting edge portion 43 having a rectangular cross section is provided at an eccentric position on the lower surface thereof. The die 41 punches 39 as shown in FIG.
A cutting edge portion 45 corresponding to the cutting edge portion 43 and a product dropping hole 47 are provided.

The punch 39 is prevented from rotating in the punch guide 49 by the rotation preventing device 51, and freely slides in the vertical direction. Further, the punch guide 49 is prevented from rotating in the upper turret 7 by the rotation preventing device 53, and freely slides in the vertical direction. A plate retainer 55 is provided with a spring 57 at the lower end of the punch guide 49.
It is installed by. Punch 39 and punch guide 49
Are supported by strip springs 59 and lift springs 61, respectively.

The die 41 is a die holder 63 attached to the lower turret 5.
It is positioned and fixed by a positioning device 65, and a product guide hole 67 is provided in the lower turret 5.

If the joint portion 37 of the work W having a plurality of small semi-finished products is positioned to the cutting edge portion 45 of the die 41 of this product take-out die by NC control as shown in FIG. 3 and punched, the joint portion 37 is formed. Is cut and the product is collected in the product container through the product drop hole 47. The size of the product is limited by the size of the product drop hole, but depending on the size of the punch die, it is possible to process fairly large products and even smaller ones that are difficult to drop with a chute device.

[Effects of the Invention] As can be understood from the above description of the embodiments, in short, the present invention provides a die including a punch (39) and a die (41), in which the die (41) is connected to the die (41). A large product drop hole (47) including the center of (41) is provided, and the work (W) and the product are cut at a position close to the product drop hole (47) at an eccentric position of the die (41). A cutting blade portion (45) for separating is provided, and a cutting blade portion (43) corresponding to the cutting blade portion (45) of the die (41) is provided in the punch (39).

As is apparent from the above configuration, in the present invention, the die 41 is provided with the product drop hole 47 and the cutting edge portion 45, and the punch 39 has the cutting edge portion 43 corresponding to the cutting edge portion 45 of the die 41. It is provided.

The product drop hole 47 is formed to be large including the center of the die 41, and the cutting edge portion 45 is provided at a position close to the product drop hole 47 at an eccentric position of the die 41.

Therefore, after the product of the work W is positioned in the product drop hole 47, when the product is cut and separated from the work W by the cutting edge part 43 of the punch 39 and the cutting edge part 45 of the die 41, the product immediately enters the product drop hole 47. Since the product is dropped and carried out, the product can be cut and separated from the work W at the same high speed as the normal punching process.
