Abstract
The utility model discloses a pin hole punching head, and relates to improvement of moulds and location pin hole punching heads. The utility model provides a pin hole punching head which is convenient to use and low in manufacturing cost. The pin hole punching head is vertically arranged on a lateral surface of an upper mould, facing towards a lower mould, and is matched with the upper mould; the pin hole punching head is cylindrical, the bottom surface of the pin hole punching head is machined into a punching cutting edge, and the bottom surface of the pin hole punching head is vertical to the axis of the pin hole punching head. In the pin hole punching head, the 90-degree included angle formed by the bottom surface and the lateral surface of the pin hole punching head is used as the punching cutting edge, in use, the working procedure of punching can be carried out effectively; meanwhile, when the pin hole punching head needs to be taken out, a bolt is mounted in a threaded hole which is formed at the center of the bottom surface, the pin hole punching head can be taken out conveniently and simply by pulling the bolt; on the other hand, the pin hole punching head is designed to be cylindrical, and the complex shape of the pin hole punching head is changed, thus, the pin hole punching head is simple and reliable, and the manufacturing cost of the pin hole punching head is reduced greatly.
Description
Technical field
The utility model relates to pin-and-hole drift field, relates in particular to the improvement of die positioning pin hole drift.
Background technology
In mold use, for the mould grinding benchmark in later stage, usually use the pin-and-hole drift to carry out punching in drawing operation, as shown in Figure 5, after punching is completed, the bolt suitable with it of packing in the screwed hole of pin-and-hole drift cutting edge center, then by bolt, the pin-and-hole drift is taken out.At present, most of pin-and-hole drifts as shown in Figure 4, have caused high manufacturing cost due to its complicated shape, have brought great inconvenience to production and application.
Summary of the invention
The utility model is for above problem, and a kind of pin-and-hole drift of easy to use and low cost of manufacture is provided.
The technical solution of the utility model is: vertically be located at patrix on a side surface of counterdie and suitable with described patrix, described pin-and-hole drift is column type, the bottom surface of described pin-and-hole drift is processed as the punching cutting edge, and the bottom surface of described pin-and-hole drift is vertical with the axis of pin-and-hole drift.
The bottom center position of described pin-and-hole drift offers screwed hole.
The bottom center position of described pin-and-hole drift offers groove, and described screwed hole is opened in the center of described groove.
The utility model uses 90 degree angles of pin-and-hole drift bottom surface and side surface formation as the punching cutting edge, in use, can effectively carry out the punching operation; Simultaneously, when taking out the pin-and-hole drift, the screwed hole of offering in the bottom center bolt of packing into takes out the pin-and-hole drift by pulling bolt, very simple and convenient; On the other hand, the pin-and-hole drift is made as column type, has changed its complicated shape, make it simple and reliable, significantly reduced its manufacturing cost.

Fig. 4 is the structural representation of background technology in the utility model,
Fig. 5 is the embodiment schematic diagram of background technology in the utility model;
In figure, 1 is the pin-and-hole drift, the 10th, and punching cutting edge, the 11st, bottom surface, the 110th, screwed hole, the 111st, groove, the 2nd, patrix, the 3rd, counterdie.
The specific embodiment
The utility model is as shown in Fig. 1-5, vertically be located at patrix 2 on a side surface of counterdie 3 and suitable with described patrix 2, described pin-and-hole drift 1 is column type, the bottom surface 11 of described pin-and-hole drift 1 is processed as punching cutting edge 10, and the bottom surface 11 of described pin-and-hole drift 1 is vertical with the axis of pin-and-hole drift 1.Use 90 degree angles of bottom surface 11 and side surface formation as punching cutting edge 10, in use, can effectively carry out the punching operation, as shown in Figure 2; On the other hand, pin-and-hole drift 1 is made as column type, has changed its complicated shape, make it simple and reliable, significantly reduced its manufacturing cost.
11 centers, bottom surface of described pin-and-hole drift 1 offer screwed hole 110.Like this, when needs took out pin-and-hole drift 1, the bolt of packing in screwed hole 110 can take out pin-and-hole drift 1 by pulling bolt, as shown in Figure 3, and very simple and convenient.
11 centers, bottom surface of described pin-and-hole drift 1 offer groove 111, and described screwed hole 110 is opened in the center of described groove 111.Like this, can effectively prevent the orifice deformation of screwed hole 110, the problem that when having avoided because of punching, the damage in double thread hole causes bolt to be difficult to screw in.
Technique effect of the present utility model: make its structure more simple, use conveniently, when can carrying out effective punching, significantly reduced its manufacturing cost.
Claims (3)
