Abstract

The utility model relates to a stamping terrace die, especially to a long and round stamping terrace die. A long and round stamping terrace die body and a terrace die fixing plate are prepared separately and then combined together, thereby solving the problem of processing difficulty and short service lifetime of terrace dies in the prior art. The terrace die in the utility model includes the long and round terrace die body and the terrace die fixing plate. The terrace die body and the terrace die fixing plate are processed and formed separately. A hole is arranged in the top center of the long and round terrace die. A through groove and a non-through groove are arranged in the center of the terrace die fixing plate. A top end of the long and round terrace die is inserted into the through groove of the terrace die fixing plate. A limit pin which is inserted into the hole of the long and round terrace die is disposed in the non-through groove in the terrace die fixing plate. In the utility model, an integral structure is adopted in the long and round terrace die profile. A hole, grooves and a pin are arranged in a portion of the top of the long and round terrace die cooperating with the fixing plate in a fixed manner. Thus, the processing technique of the long and round terrace die is simplified, the processing cost is reduced, and the processing efficiency and the service lifetime of the long and round terrace die are improved.

Description

The oval punch of a kind of punching press

Technical field:

The utility model relates to a kind of diel, the oval punch of particularly a kind of punching press.

Background technology:

At present, oval punch generally comprises oval punch body and punch retainer two parts in the blanking and punching mould, usually is formed in one.Owing to be subjected to structural limitations, its processing method has at present: one, profile digital control processing, adopt this kind method because oval punch profile is little, clamping inconvenience in numerical control; Two, process profile with machine tool, the later stage pincers worker is repaiied with model and is ground, and this kind method often causes oval punch profile and dimensional accuracy not high.This shows that these two kinds of processing method costs are too high and efficient is too low; In addition, because its one-body molded difficulty that increases mould processing technology, thereby cause between mould punch and die gap inhomogeneous service life that influences mould easily.

Summary of the invention:

The utility model is connected oval punch body then with punch retainer split manufacturing, has solved its processing and manufacturing difficulty and low problem of life-span.

The utility model is realized by following technical scheme:

The oval punch of a kind of punching press, comprise oval punch body and punch retainer two parts, the machine-shaping respectively of oval punch body and punch retainer, center, oval punch body top has the hole, the punch retainer center has a through slot and a non-through groove vertical with through slot, insert in the through slot of punch retainer on oval punch body top, and spacer pin inserts in the hole of oval punch body and is positioned in the non-through groove on the punch retainer.

Oval punch profile of the present utility model adopts the entire body structure, and oval punch top and fixed head secure fit are partly punched and worn pin, have simplified oval punch processing technology, have lowered cost, has improved the service life outside working (machining) efficiency and the oval punch.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

Mould structure of the present utility model such as Fig. 1, Fig. 2, shown in Figure 3, it comprises punch retainer 1, oval punch body 2 and spacer pin 3.Oval punch body 2 adopts the entire body structures, adopt heat treatment in the process after the line cutting directly be cut into, the working hole that punch retainer 1 and oval punch body 2 cooperate can digital control processing or the line cutting process at one time.When work by the oval punch body 2 of spacer pin 3 restrictions because and the frictional force effect between the stamping parts from punch retainer 1, extract downwards.

Claims

1. oval punch of punching press, comprise oval punch body and punch retainer two parts, it is characterized in that: the machine-shaping respectively of oval punch body and punch retainer, center, oval punch body top has the hole, the punch retainer center has a through slot and a non-through groove vertical with through slot, insert in the through slot of punch retainer on oval punch body top, and spacer pin inserts in the hole of oval punch body and is positioned in the non-through groove on the punch retainer.
