Abstract

The invention discloses a press die. The press die comprises an upper die block (2) and a lower die block (5). The upper die block (2) and the lower die block (5) are parallel to each other. A buffer rod (3) is arranged between the upper die block (2) and the lower die block (5). A die shank (1) connected with a driving device is arranged on the upper surface of the upper die block (2). A die head fixing buckle (8) is arranged on the end face, facing the lower die block (5), of the upper die block (2). A mounting hole (7) is formed in the upper surface of the die head fixing buckle (8). A groove (9) is formed in the end face, facing the die head fixing buckle (8) of the upper die block (2), of the lower die block (5). A fixing hole (6) is formed in the groove (9). The press die has the advantages of being good in damping effect, long in service life and high in universality.

Description

A kind of diel

Technical field

The present invention relates to diel, particularly a kind of diel.

Background technology

Thin type Mould Machining, as chute, through hole, axle head is all to need accurate punch press to process, although current punch press can, by computer control precision, due to structure influence own, often can not very accurately and delay the converted products of pressing, this is because lathe impacts larger, parts after processing occur that the situation of distortion is more, and the suffered impact of mould is larger, causes mould concave-convex mold fragile, thereby increased processing cost, affected operating efficiency.

Summary of the invention

The object of the invention is to overcome the shortcoming of prior art, a kind of diel is provided.

Object of the present invention is achieved through the following technical solutions: a kind of diel, it comprises upper module, lower module, described upper module and the lower module layout that is parallel to each other, is provided with buffer bar between upper module and lower module, is provided with the die shank for connecting drive device on upper module upper surface, a face down end face of module of upper module is provided with die head clip, die head clip is provided with installing hole, and lower module is provided with groove towards the end face of the die head clip of upper module, is provided with fixing hole in groove.

Described 8 one-tenth " L " shapes of die head clip.

In the middle of described buffer bar 3, be provided with the spring body 4 in order to damping.

Described elastomer 4 springs or elastic plastic.

The present invention has the following advantages: diel of the present invention, adopt elastomer damping, the suffered stamping press of lower module is reduced, extended the service life of lower module, and this diel punch and die can combine replacing, thereby reduced the production cost of diel, increased the versatility of diel.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention

In figure, 1-die shank, 2-upper module, 3-buffer bar, 4-elastomer, 5-lower module, 6-fixing hole, 7-installing hole, 8-clip, 9-groove.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:

As shown in Figure 1, a kind of diel, it comprises upper module 2, lower module 5, described upper module 2 and lower module 5 layout that is parallel to each other, between upper module 2 and lower module 5, be provided with buffer bar 3, in the middle of buffer bar 3, be provided with the spring body 4 in order to damping, elastomer 4 springs or elastic plastic, on upper module 2 upper surfaces, be provided with the die shank 1 for connecting drive device, a face down end face of module 5 of upper module 2 is provided with die head clip 8, 8 one-tenth " L " shapes of die head clip, die head clip 8 is provided with installing hole 7, lower module 5 is provided with groove 9 towards the end face of the die head clip 8 of upper module 2, in groove 9, be provided with fixing hole.
