Abstract

A hard alloy assembling die comprises a middle die, vibration-reduction layers and a lower die, the middle die is tightly matched with the lower die, and the outer portion of the middle die and the outer portion of the lower die are respectively provided with one vibration-reduction layer. According to the hard alloy assembling die, the inner portion of the middle die and the inner portion of the lower die are respectively of an alloy structure, and a die element of the middle die and a die element of the lower die are respectively made of hard alloy. According to the hard alloy assembling die, the service life of the die is greatly prolonged, a tampered running pulley is free of an annular belt and a burr edge, and the working allowance is accurate.

Description

The combination die of hard metal article tool

Technical field

The utility model relates to mould, is specially the combination die of hard metal article tool.

Background technology

Current mould is all the inner mould core that adopts general die steel to do, and through we scientific research personnel's unremitting effort, finally finds the better material that can substitute it, carbide alloy.It is indeformable that the mould of making of carbide alloy has mould, and the constant product quality that processes is unified, thereby the labour who has greatly saved the workman has reduced the lead-time, improved operating efficiency.Existing technical disadvantages is: 1, the service life of mould is short; 2, the quality of mould is unstable; 3, the product size precision processed is little; 4. inefficiency.

The utility model content

The technical problem that the utility model solves is to provide the combination die of hard metal article tool, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions:

The combination die of hard metal article tool, comprise middle mould, buffer layer and counterdie, and described middle mould and counterdie closely cooperate, and described middle mould and counterdie outside all are equipped with buffer layer.

In the utility model, middle mould and counterdie inside are alloy structure, and middle mould and counterdie all adopt core rod that carbide alloy is done.

Beneficial effect: the utility model has extended the service life of mould greatly, and upsetting roller out is without endless belt without burr, and allowance is accurate.

The accompanying drawing explanation

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

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1, the structural representation of combination die of hard metal article tool, the combination die of hard metal article tool, comprise middle mould 1, buffer layer 2 and counterdie 3, and described middle mould 1 and counterdie 3 closely cooperate, and described middle mould 1 and counterdie 3 outsides all are equipped with buffer layer 2.

In the utility model, middle mould 1 and counterdie 3 inside are alloy structure, and middle mould 1 and counterdie 3 all adopt core rod that carbide alloy is done.

The utility model in use, can repeatedly be used and indeformable, has wearability preferably, has greatly extended service life, and compacting product out has smooth surface, the feature of excellent performance, the long service life of mould; The steady quality of mould; The product size precision processed is high; High efficiency.

Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, that in above-described embodiment and specification, describes just illustrates principle of the present utility model, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall in claimed the utility model scope, the claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. the combination die of hard metal article tool, is characterized in that, comprises middle mould, buffer layer and counterdie, and described middle mould and counterdie closely cooperate, and described middle mould and counterdie outside all are equipped with buffer layer.
