Abstract

PURPOSE:To reduce the cost of die by providing a guide holder used for holding a workpiece separately from a die set of lower die and disposing movably the die set of lower die. CONSTITUTION:A guide holder 9 for holding a workpiece 15 is fixed to a guide plate 8a and is disposed separately from a die set 6 of lower die. On the other hand, both of a die set of upper die and the die set 6 attached with a bending die 5 and a bending punch 7 are installed to be freely movable in the 17 direction by a servomotor 2 through a control device 2a. In working a metallic sheet 16 similar in shape to a metallic sheet 15 and different in bending position, etc. from the sheet 15, the sheet 16 is moved linearly to the 17 direction by driving the servomotor 2. The movement in the perpendicular direction to the 17 direction is performed by moving the whole body of a base plate 18 with the aid of a hydraulic cylinder, etc. In this way, the cost of dies and related facilities is reduced.

Description

[Detailed Description of the Invention] [Object of the Invention] Industrial Field of Application The present invention relates to a press processing device for metal plates, and among the elements constituting the mold, a mold for a cutting blade unit such as a punch or a goose. This relates to a press mold device that can be moved independently and individually, and that can accommodate variable factors such as dimensions and punches that vary from product to product.

(Prior art) As a prior art related to the present invention, Japanese Patent Application Laid-Open No. 57-1605
There is a publication titled No. 99 "Press processing equipment for all bottom plate products".

This is a press processing device that obtains a product by applying different press processes to the same part of a metal plate multiple times. An operating block corresponding to an unused press upper die is moved back and forth by a block drive device, and when the ram is lowered, the operating block is lowered into the measuring space of an unused press upper die. This is a press processing device for products.

However, in the above-mentioned press processing equipment, the mold consisting of the upper die and the lower die is fixed and does not move, and the operation block that moves the upper die up and down is blankly struck. It is possible to press products of the same shape without having to attach or detach the press mold each time the type of processing changes, but if the shape is slightly different or the hole diameter or notch dimensions differ depending on the product, In the case of a different ivy shape, such as when changing to the right or left, there is a drawback that the mold must be completely changed and set up.

(Problems to be solved) The technical measures taken to solve the above technical problems are:
The technical challenge is to create a mold structure that can accommodate variable factors such as shape, dimension, and pitch, which are slightly different for each product in the production of a wide variety of press-molded products in small quantities.

[Structure of the invention]

(Means to solve the problem) The technical measures taken to solve the above technical problem are:
When manufacturing a similar product in which one dimension of the product shape has changed, such as when the shape of a product formed by press processing changes, the position of the hole changes, or the bending position of a bracket etc. This mold device allows the upper and lower die sets of the mold to be moved linearly in the X-axis and Y-axis directions using a control device such as a servo motor, cylinder, or cam mechanism. By fixing to the positioning holder and moving the mold device,
It is possible to immediately respond to changes in shape, perforation position, bending position, and rib position.

The amount of movement in the X-axis direction is Xi, X2. X3. ...,Y
The amount of movement in the axial direction is Yl, Y2. Y3. Even a small amount of movement can be carried out with one mold device by controlling the movement of a servo motor or hydraulic cylinder.

(Operation) The above technical means operates as follows. In other words, when pressing a large number of similar products in small quantities,
If the position of the hole at a certain distance from the reference position changes in the X-axis direction or Y-axis direction, for example, by about 0.5 to 2.0 fl in the X-axis direction, the mold should usually be changed. According to the apparatus of the present invention, individual cutting blade units consisting of movable cutting blade units configured in advance by the action of a servo motor, hydraulic cylinder, or cam mechanism according to instructions from a control device are used to perform press working. The mold is moved in the X-axis direction or Y-axis direction, and after the mold is fixed, press processing is performed.
It is possible to freely respond to changes in dimensions within a certain range.

In this manner, by moving in the X-axis direction and the Y-axis direction in one mold device, it is possible to respond to variations in two dimensions in a simple manner.

(Example) Specific examples will be described below.

1 is a mold device that can be moved laterally (in the X-axis direction) by a servo motor 2, 2a is a control device, 3 is an embodiment of a bending mold device for a workpiece, and includes an upper mold die set 4, a bending die 5
6 is a lower die set and 7 is a bending punch. 8a and 3b are guide plates, and a guide holder 9 is fixed to 8a. 10 is a positioning pin fixed to the guide bolt 9, and 0 does not indicate the position of the positioning pin. Reference numeral 11 is a guide boss, and 12 is a spring, and the upper mold die set 4 is attached to the lower mold die set 6 so as to be freely vertically movable. There is a halter 13 and a spring 14 that hold down one end of the workpiece of the metal plate 15 shown by the chain line, and 17 is the moving direction (X-axis direction) of the lower die set 18 is the die set 4.5. Servo motor 12
and a substrate on which the guide holder 9 is fixed.

In the above configuration, the function of the bending press for similar shaped metal plates 15 and 16 will be described.
a is inserted into the positioning pin 10 of the holder 9 for positioning, and then the bending process is carried out according to this embodiment, in which the upper mold die set 4 is lowered by a ram (not shown) and the metal plate 15 is bent at the bending position 15b. 16 has a similar shape and the bending position 16a is 1.
5, and the dimensions of the positioning hole and the bending position are different. If Xt>X2, the servo motor 2 is rotated by the control device 2a, and Xl-X2=
If K is attached to the lower die set 6, the upper die set 4, the bending die 5, and the bending punch 7 are
7, move it linearly to the right. Next, the upper die set 4 is lowered and the metal plate 16 is bent to produce the product B.

In this way, metal plates of different shapes can be bent using the same mold by moving the position of the mold using a drive device, and further, holes can be punched and punched using the above-mentioned spacing method. .

Movement in the Y-axis direction by changing the position of the holes in the metal plate 15 can also be achieved by using a separate guide holder 9 (not shown) and moving the substrate 18 in the Y-direction using a hydraulic cylinder.

[Special effects of the present invention]

The present invention produces the following unique effects. In other words, it is possible to process similar products with one mold device, and it is possible to immediately respond to variable factors such as shape and dimensions without changing the mold, but in addition (11) when you want to process a new similar product, , there is no need for new molds and mold equipment, etc., (2) less manual labor is required for setup change of mold equipment, it can be done in an extremely short time, and it can be done automatically, (3) a wide variety of types. The number of molds for similar products can be reduced, and storage space for molds is unnecessary.
