Description
Technical field
The utility model relates to a kind of I-shaped perforating die, is used for the moulds of industrial equipment in the hole of punching press disk class part.
Background technology
Originally the hole of sheet class part need directly be put into part on the special perforating press, does not have special fixing tool during punching, in the process of punching, dashes partially easily, causes part to scrap.
Summary of the invention
The technical problem that the utility model will solve provides a kind of I-shaped perforating die, and this mould is not only simple in structure, and the location can satisfy the part punching time and clamp function, and the size that processes hole dimension satisfies specification requirement.
For overcoming the above problems; The concrete technical scheme of the utility model is following: a kind of I-shaped perforating die; Horizontal direction at U-shaped mould body is provided with the set bolt that is threaded; Vertical direction at U-shaped mould body is provided with the jam-packed bolt that is threaded, and the bottom surface of jam-packed bolt contacts with the upper surface of set bolt; Openend at U-shaped mould body is provided with punching head, is provided with base in the open inner ends side of U-shaped mould body, and the position of base is corresponding with the position of punching head; Upper surface at U-shaped mould body is provided with hook, connects flexure strip on the hook, is provided with groove at the excircle of punching head, and the other end of flexure strip is connected with the groove of punching head.
The front end of described set bolt is a V-shape, and this V-shape structure can make in the V-shaped part of ring washer location, thereby makes the pad accurate positioning.
This I-shaped perforating die adopts said structure, can disk class part effectively be located, and can upspring automatically after the punching press, thereby increase work efficiency, and guarantees product quality.
Description of drawings
Fig. 1 is the structural representation of I-shaped perforating die.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1, a kind of I-shaped perforating die is provided with the set bolt 2 that is threaded in the horizontal direction of U-shaped mould body 1, is provided with the jam-packed bolt 3 that is threaded at the vertical direction of U-shaped mould body 1, and the bottom surface of jam-packed bolt 3 contacts with the upper surface of set bolt 2; Openend at U-shaped mould body 1 is provided with punching head 5, is provided with base 6 in the open inner ends side of U-shaped mould body 1, and the position of base 6 is corresponding with the position of punching head 5; Be provided with hook 7 at the upper surface of U-shaped mould body 1, connect flexure strip 8 on the hook 7, be provided with groove 8 at the excircle of punching head 5, the other end of flexure strip 9 is connected with the groove 8 of punching head 5.
As shown in Figure 2, the front end of described set bolt 2 is a V-shape.
During work, earlier set bolt 2 is regulated through screw thread, guaranteed the accurate positioning of part, with jam-packed bolt 3 set bolt 2 is compressed then; Part is put in the V-type opening of set bolt 2, carried out punching press with punching head 5, the hole of sheet shape part is that punching press is accomplished.
