Description

[Detailed description of the invention] This invention can position the blank on the side, and by arranging a plurality of positioning pins that can sink under the weight of the blank when it is placed, it can be used in various ways. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention, which relates to a die plate that enables positioning and drilling of blanks having various shapes, will be described below with reference to the drawings.

In the figure, the die plate 1 of the present invention includes a plurality of positioning pins 3 that are pre-installed in accordance with the arrangement of the blanks 2.

In this embodiment, the blank 2 is formed into a rectangular shape, for example, to be used as a rectangular piece of hardware for construction or a metal piece that can be bent and folded. The flange part 6 is expanded at the lower end of the body part 5, and the blank 2 is large and small so that the blank 2 can be positioned on the side surface of the body part 5.
, 2 and in such a way that its opposing side surface matches the shape of the blank 2, and the positioning pin 3
As shown in FIG. 2, it is inserted into a stepped hole 9 having a hole 7 with a large inner diameter on the lower side, and the raised position is regulated by the flange 6 coming into contact with the stepped portion 10.

Further, the positioning pin 3 is urged upward by a spring 13 interposed between the backing plate 12 at the lower end of the die plate and the flange portion 6, and protrudes from the upper surface of the die plate 1-1.

In FIG. 1, reference numerals 15, . . . are punches installed in a punch plate 16 which cooperates with the punch holes 4 to punch the blank 2.

However, in the die play 1-1 of the present invention, for example, when punching a large blank 2, the blank 2
By inserting the small blank 2 between the positioning pins 3 located on the outer periphery, the positioning pins 3 can be positioned respectively on the opposing inner surfaces of the positioning pins 3, and the positioning pins 3 located on the inside for positioning the small blank 2 can be When a large blank 2 is placed, it sinks due to its weight.

Further, when drilling a blank 2 having a small size, a positioning pin 3 located inwardly is used.

At that time, the punch hole 4 located outside the blank 2
a. The punch 15a has free movement so that more holes 9 can be added to the larger blank 2 than to the smaller blank, as shown in FIG.

As mentioned above, the die plate of the present invention is equipped with positioning pins that can sink in response to the weight of the blanks so that blanks of different shapes can be positioned, so the positioning pins can be adjusted according to the blanks. It is possible to perform drilling work on many types of blanks without changing the position, and the effort required for setup changes can be greatly reduced.

In addition, the die plate of the present invention can be provided with a pilot pin as appropriate, and the pilot pin can also be formed to be able to move up and down. It is also possible to make the positioning pin for positioning function as a pilot pin.
