BACKGROUND OF THE INVENTION
The present invention relates to a processing switching press die that can be used to switch processing used for punching or bending thin plate members made of a resin material or a metal material.
[0002]
[Prior art]
A conventional press die will be described with reference to the drawings. FIG. 5 is a cross-sectional view of a principal part of a conventional press die.
[0003]
In FIG. 5, reference numeral 1 denotes a hoop material as a material to be pressed, which is a plate-like material made of a resin material or a metal material, and is conveyed and supplied in the arrow feed direction. Reference numeral 21 denotes a punch, which is provided with a processing portion 31 at the lower end and is fixed to the punch plate 24 at the top.
[0004]
28 is a material holding plate provided with a hole 34 through which the punch 21 is inserted, and a hole 35 through which the processed portion 31 is inserted at the lower end of the hole 34, 23 is an upper backing plate closely contacting the upper surface of the punch plate 24, and 22 is an upper backing plate. The punch holder is in close contact with the upper surface of 23.
[0005]
Reference numeral 27 denotes a suspension bolt in which the upper end of the material presser plate 28 is fixed to the lower end. The main body of the suspension bolt is inserted through the insertion hole communicating with the punch plate 24 and the upper backing plate 23 so that the upper end is vertically movable. It protrudes into a hole provided in the movable punch holder 22, and a material presser plate 28 is biased downward by a compression spring 26 and a set screw 25 installed in the hole.
[0006]
A die plate 29 is provided with a processing hole 32 into which a processing portion 31 provided at the lower end of the punch 21 is fitted, and a die holder provided with an excluded hole 33 of a processed unnecessary member communicating with the processing hole 32. It is in close contact with the upper surface of 30.
[0007]
In the press die configured as described above, the hoop material 1 is conveyed and supplied in the direction of the arrow by a predetermined dimension, and then the punch 21 is lowered via the punch holder 22 so that the processed portion 31 of the punch 21 and the die plate The punching process of a predetermined shape is performed at a predetermined portion of the hoop material 1 by the 29 processing hole portions 32.
[0008]
Next, a plurality of press workings having different shapes such as product type switching will be described. FIG. 6 is a plan view of the main part of the hoop material punched out by a press die. FIG. 6A shows the hoop material 1 in which the round hole 1a and the square hole 1b are collinear with the feeding direction of the hoop material 1. FIG. 6B shows an example in which the circular holes 1a and the square holes 1b are provided at the same horizontal interval and at the vertical interval of the dimension C. FIG.
[0009]
As described above, each of them was press-worked using a dedicated die in which a necessary number of punches having different shapes of the round hole 1a and the square hole 1b were installed.
[0010]
[Problems to be solved by the invention]
However, in the conventional press mold, FIGS. 6A and 6B have the same horizontal distance but different vertical dimension C. Therefore, the press mold for processing both is the same for the same hoop material 1. Each one needed its own.

Further, the press die has a structure to be attached to the press machine, and it is necessary to attach and detach the press die from the press machine every time the shape is changed such as the processing position, the number of processing and the punching processing, that is, the processing is switched. There was a problem that switching man-hours were required.
[0012]
The present invention is intended to solve the above-described conventional problems, and it is not necessary to attach and detach a press die from a press machine, easy to change the processing, has few man-hours for switching, and performs a plurality of processing with one press die. The object of the present invention is to provide a processing switching press die that can cope with the above.
[0013]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the processing switching press die of the present invention is a bottom plate in which a positioning pin, a concave groove is provided on the lower surface, and a die plate provided with a processing hole portion for forming a predetermined processing shape of the material to be pressed is adhered to the upper surface. Select and insert a positioning pin into one of a plurality of positioning holes provided in the backing plate and the lower backing plate, and insert the lower backing plate into the recessed groove to be set and mounted at a predetermined pressing position of the material to be pressed A guide block to be regulated is provided on the upper surface, and a post that moves together with the punch holder has a die holder that has an insertion hole correspondingly inserted in the movement setting range, and a punch that faces the machining hole is fixed. The upper backing plate with the punch plate in close contact with the lower surface and the upper backing plate linked to the setting mounting of the lower backing plate Are those constituted by the vertical movable punch holder for mounting is set to a predetermined position, the processing switching is possible easily in a short time.
[0014]
