Abstract
The utility model provides a stamping die. One or more layers of elastic annular gaskets are arranged on the periphery of a male die. Fragments generated in stamping can not be splashed to the surface of the male die of the stamping die, the probability of the stamping die to be abraded by the fragments can be reduced, and the buffering function can be further achieved to a certain degree. By means of protection of the elastic annular gaskets, the service life of the stamping die can be greatly prolonged, the cost is saved, and the economical benefits are improved.
Description
Technical field
The utility model belongs to mould applications, particularly diel.
Background technology
Many mechanical parts that the portable computer parts of take are representative, require will continue from now on to the trend of high strength, lightweight development, thereby will continue to strengthen the processing of high strength steel.Cold punching processing has now reached 980MPa, and the heat punching has surpassed 1500MPa, and the upper limit future of the scope of application of cold punching processing further improves.And for the cold-punching mold of high strength steel easily produce the wearing and tearing of scuffing, corner angle part, because the slip of goods produces the problems such as face crack, be badly in need of at present the diel material of the new adaptation high strength steel of research and development and the methods that die surface is processed.
Summary of the invention
The purpose of this utility model is to provide a kind of diel, can prevent the scuffing of punching press chip to mould, thereby realizes the purpose that extends die life.
For realizing above purpose, the technical solution of the utility model is:
Diel of the present invention, comprise patrix and punch, and patrix coordinates up and down with punch; in order to stamped workpieces, be provided with the ring washer that prevents that convex mould surface from scratching around punch, in process; after completing a punching press, described ring washer can recover rapidly to protect punch.Ring washer around punch is one or more layers.
The material of ring washer is soft rubber.
The internal diameter of ring washer equates with the external diameter of diel punch or the internal diameter of ring washer is less than the external diameter of diel punch.
Spring also is set below ring washer, and spring connects punch and ring washer.
Splash into 0.1-5ml lubricating oil in ring washer, can play better protection effect.
The beneficial effects of the utility model are:
1, at a whole set of mould, do not do under the prerequisite of significantly changing, only need to add ring washer can play good effect.
2, the ring washer simple and durable.
3 installations of the present utility model are without special standby personnel, and those of ordinary skill can be competent at.
The accompanying drawing explanation
Fig. 1 is the mould schematic diagram after the utility model embodiment 1.
Fig. 2 is Fig. 1 convexity tool sectional view.
The mould schematic diagram of Fig. 3 after for this use new embodiment 2.
The stereogram that Fig. 4 is embodiment 2 ring washers and spring.

The specific embodiment
Further illustrate with reference to the accompanying drawings a kind of embodiment of the present utility model.
Embodiment 1,
Diel of the present utility model; comprise patrix 3 and punch 6; patrix 3 coordinates up and down with punch 6; in order to stamped workpieces, be provided with the ring washer 5 that prevents punch 6 surface tears around punch 6, in process; after completing a punching press, described ring washer 5 can recover rapidly to protect punch.
Diel of the present utility model; comprise patrix 3 and punch 6; patrix 3 coordinates up and down with punch 6; in order to stamped workpieces, be provided with ring washer 5 and the spring 8 that prevents punch 6 surface tears around punch 6, in process; after completing a punching press, described ring washer 5 and spring 8 can recover rapidly to protect punch.
The above not imposes any restrictions this novel technical scope, and all any modification, equivalent variations and modifications of above embodiment being done according to the utility model technical spirit all still belong in the scope of this novel technical scheme.
