Abstract
The utility model discloses a cold extrusion forming die which comprises a female die body (1), a left splicing block (2) and a right splicing block (3) and is characterized in that the female die body (1) is combined with the left splicing block (2) and the right splicing block (3) in a split manner, namely that the left splicing block (2) and the right splicing block (3) are embedded into the female die body (1). Due to the adoption of the structure, the processing cost of the die is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of cold extrusion molding mould, especially relates to a kind of cold extrusion shaped die field.
Background technology
What at present a lot of miniature parts still adopted is traditional machine cut processing, and not only raw materials consumption is big, complicated because of manufacturing procedure simultaneously; Single-piece work is consuming time many, and production cost is high, and economic benefit is low; In addition, the single-piece production manually-operated, 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, has improved production efficiency greatly, has reduced raw-material waste; The uniformity of product quality also is guaranteed, and has obtained using widely at automobile, non-ferrous metal industry.In the cold extrusion shaped use of non-ferrous metal industry, also find the weak point of die in making and using, like the whole die of the part of processed complex, because complex process, machining accuracy can not guarantee, and the mould maintenance cost is very high.
Summary of the invention
The purpose of the utility model provides a kind of cold extrusion molding mould, and the technical problem that can solve is: be convenient to the processing and manufacturing of molding concave die, improve machining accuracy, reduce the Mould Machining cost, prolong the service life of mould.
The problem of the required solution of the utility model is to realize through following technical scheme: comprise die body, left piece, right piece; It is characterized in that said die body and left piece, right piece process separate assembling, promptly left piece and right piece are embedded on the die body.
The utility model compared with prior art has following advantage:
1. split-type structural, die body, left piece, right piece are separately made, and precision is high;
2. can partly change, die life is long, and cost is low;
3. improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Shown in Figure 1 is the structural representation of the utility model
Shown in Figure 2 is the vertical view of the structural representation of the utility model
1. left piece 2. right piece 3. die bodies among the figure.
The specific embodiment
Can know that by figure this cold extrusion molding mould comprises die body 1, left piece 2, right piece 3, said die body 1 and left piece 2, right piece 3 are processed separate assembling, and promptly left piece 2 is embedded on the die body 1 with right piece 3.
When the utility model cold extrusion molding mould was made, die body 1 material adopted 45# steel wire excision forming, and left piece 2, right piece 3 materials adopt CY12Mo; Quenching hardness HRC55-62; Go into modular angle repetition test and practice, go into modular angle at 12 °-18 °, it is moving to help the metal circulation; Reduce the wearing and tearing of die, improve the life-span of mould; Process die body 1, left piece 2, right piece 3 split type.During extrusion sections, this mould is contained in the die frame of hydraulic press, blank to be processed is put into mould, being pressurizeed by hydraulic press is squeezed into the part of requirement, processes finished product.
Obviously; The foregoing description of the utility model only be for explain clearly that the utility model does for example; But be not used for limiting the scope of the utility model; All technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each item claim.
Claims (1)
1. a cold extrusion molding mould comprises die body, left piece, right piece, it is characterized in that said die body and left piece, right piece process separate assembling, and promptly left piece and right piece are embedded on the die body.
