Abstract

The utility model discloses a split extrusion punch which is applied to an extrusion forming die for a metal inner cavity. The split extrusion punch comprises a punching part and a base body part which are connected through a demountable structure. According to the extrusion punch, after being worn, only the punching part is needed to be replaced, so that the waste of materials can be effectively reduced, and production cost can be reduced.

Description

Split type extruding drift

Technical field

The utility model relates to a kind of machining equipment field, especially a kind of extruding drift that is applied in the metal inner cavity extrusion molding dies.

Background technology

In the metal inner cavity extrusion forming process, the extruding drift pushes the metal in the metal inner cavity and forms the part identical with the metal inner cavity shape, makes the internal structure of metal product and surface quality perfect more.Because in the extrusion process, the operating ambient temperature of extruding drift is high, pressure is big, therefore high to extruding drift quality requirement, need the extruding drift to have very strong high temperature resistant, high pressure and require the wear-resisting performance of extrusion head.

Present existing extruding drift generally adopts integral structure, and the extruding drift is through after being in a period of time of working under high temperature, the hyperbaric environment for a long time, and the front end wearing and tearing of extruding drift are very serious; Need change whole extruding drift; Cause the life-span of staking punch very short, waste of material is serious, and production cost is high; Especially when whole extruding drift adopts Hardmetal materials to make, whole extruding drift changed significantly improved production cost.

The utility model content

To the deficiency of prior art, the purpose of the utility model is that a kind of split type extruding drift will be provided, and this extruding drift can reduce the waste of material, reduces production costs.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:

A kind of split type extruding drift comprises pressing part and matrix part, and said pressing part is connected through a detachable structure with matrix part.

Preferably, said detachable structure comprises tenon and mortise, and said tenon is located at said pressing part rear end, and said mortise is located at the front end of said matrix part, and said tenon is connected said pressing part among embedding said mortise with said matrix part.

Further, said detachable structure also comprises some screws, and said screw passes said mortise sidewall and is connected with said tenon.

In the above-mentioned preferred implementation, said pressing part adopts Hardmetal materials to make.

Further, said matrix part adopts steel to make.

Preferably, said pressing part front end also is provided with a convexity.

With respect to prior art, the pressing part of the described split type extruding drift of the utility model is connected through a detachable structure with matrix part, after the pressing part wearing and tearing, only need change pressing part, has reduced the waste of material effectively, has reduced production cost.

For purpose, characteristic and the effect of understanding the utility model fully, below will combine accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is described further.

Description of drawings

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

Fig. 2 is the enlarged diagram at A place among Fig. 1;

Among the figure:

The 1-pressing part; 11-is protruding; The 12-tenon; The 2-matrix part; The 21-screw.

The specific embodiment

As depicted in figs. 1 and 2, a kind of split type extruding drift comprises pressing part 1 and matrix part 2, and said pressing part 1 is connected through a detachable structure with matrix part 2, when pressing part 1 is used for work metal is carried out punching press, and matrix part 2 is used to connect pressing part 1.

See also Fig. 2, Fig. 2 is the zoomed-in view at A place among Fig. 1.Detachable structure adopts mortise structure, comprises a tenon 12 and a mortise.Tenon 12 is located at the rear end of pressing part 1, and mortise is located at the front end of matrix part 2, with can pressing part 1 firmly being connected with matrix part 2 among the tenon 12 embedding mortises.In order can pressing part 1 and matrix part 2 further to be fastenedly connected, this detachable structure also comprises some screws 21, and in the present embodiment, these screw 21 quantity are two, and the sidewall that passes mortise is connected with tenon 12, and tenon 11 is embedded among the mortise securely.

Because pressing part 1 need be worked in high temperature, hyperbaric environment; Need pressing part 1 can be high temperature resistant, high strength and high-wear resistance; The carbide alloy YG20 material that pressing part 1 adopts cutting tool to use, the service life of having improved the extruding drift effectively.The more important thing is that the metal that the pressing part 1 that uses Hardmetal materials to make can bondingly not be extruded has improved the outward appearance and the performance of punching parts.In order to reduce cost, matrix part 2 can adopt steel to make, like No. 45 steel.Front end at pressing part 1 also is provided with a convexity 11, is used for extrusion metal.

With respect to prior art; The pressing part 1 of the described split type extruding drift of the utility model is connected through a detachable structure with matrix part 2; After pressing part 1 wearing and tearing, only need change, reduce the waste of material effectively, reduce production cost pressing part 1.

More than describe the preferred embodiment of the utility model in detail, the ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technical staff in the art according to the utility model design on the prior art basis through logic analysis, reasoning perhaps according to the available technical scheme of limited experiment, all should be among determined protection domain by these claims.
