Abstract
The invention discloses a cold extrusion die. The cold extrusion die comprises a female die body (1), a left splicing block (2) and a right splicing block (3). The female die body (1), the left splicing block (2) and the right splicing block (3) are made in a split combined type, namely the left splicing block (2) and the right splicing block (3) are inlaid in the female die body (1). By the adoption of the structure, the die machining cost is reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to cold extrusion die, especially relate to cold extrusion shaped die field.
Background technology
What a lot of miniature parts still adopted at present is traditional machine cut processing, and not only raw materials consumption is large, simultaneously because manufacturing procedure is complicated, single-piece work is consuming time many, and production cost is high, and economic benefit is low, in addition, single-piece production manual operation, the uniformity of product quality is also poor; In recent years, miniature parts has been started and has been utilized mould once property is cold extrusion shaped on press machine tool, substantially increases production efficiency, decreases raw-material waste, the uniformity of product quality have also been obtained guarantee, is widely used at automobile, non-ferrous metal industry.In the cold extrusion shaped use of non-ferrous metal industry, also find that die is in the weak point manufactured and in use, as the integral concave mould of the part of processed complex, due to complex process, machining accuracy can not ensure, and mould maintenance cost is very high.
Summary of the invention
The object of this invention is to provide cold extrusion die, the technical problem that can solve is: the processing and manufacturing being convenient to molding concave die, improves machining accuracy, reduces Mould Machining cost, extends the mold use life-span.
The problem that will solve required for the present invention realizes by the following technical solutions: comprise die body, left piece, right piece, it is characterized in that described die body and left piece, right piece make separate assembling, namely left piece and right piece are embedded on die body.
The present invention compared with prior art tool has the following advantages:
1. split-type structural, die body, left piece, right piece separately manufacture, and precision is high;
2. can partly change, die life is long, and cost is low;
3. improve production efficiency.
Accompanying drawing explanation
Figure 1 shows that structural representation of the present invention.
Figure 2 shows that the top view of structural representation of the present invention.
In the drawings: 1. die body, 2. left piece, 3. right piece.
As seen from the figure, this cold extrusion die, comprises die body 1, left piece 2, right piece 3, and described die body 1 makes separate assembling with left piece 2, right piece 3, and namely left piece 2 and right piece 3 are embedded on die body 1.
Detailed description of the invention
When cold extrusion die of the present invention manufactures, die body 1 material adopts 45# steel wire excision forming, left piece 2, right piece 3 material adopt CY12Mo, quenching hardness HRC55-62, enter modular angle repetition test and practice, enter modular angle at 12 °-18 °, be conducive to metal circulation dynamic, reduce the wearing and tearing of die, improve the life-span of mould; Die body 1, left piece 2, right piece 3 are made split type.During extrusion sections, be contained in the die frame of hydraulic press by this mould, blank to be processed is put into mould, being pressurizeed by hydraulic press is squeezed into the part of requirement, makes finished product.
Obviously; the above embodiment of the present invention is only for example of the present invention is clearly described; but be not used for limiting the scope of the invention, all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be limited by every claim.
Claims (1)
1. cold extrusion die, comprise die body (1), left piece (2), right piece (3), it is characterized in that: described die body (1) and left piece (2), right piece (3) make separate assembling, and namely left piece (2) and right piece (3) are embedded on die body (1).
