Abstract
The utility model provides a cold extrusion forming die of a motor housing so that the motor housing is mainly formed by cold extrusion process. The cold extrusion forming die not only solves the main problems of the element in the prior production but also improves the quality evidently and ensures that the accuracy is up to micrometer grade. The cold extrusion forming die of the motor housing comprises a convex die body and a concave die body, wherein, the convex die is fixed inside an upper die bracket through a fixed ring of the convex die, a concave die combined body is fixed inside a lower die bracket through a fixed ring component of the convex die, a mandril is arranged at the bottom of the concave die; meanwhile, the head part of the convex die and the bottom part of the concave die combined body are in the shape of a circular arc.
Description
Technical field
The utility model belongs to cold extrusion molding mould, relates generally to a kind of cold extrusion molding mould of electric machine casing.
Background technology
Electric machine casing also generally adopts foundry goods to process through machine cut at present, and so not only complex procedures consumption is many, and part quality, and especially the finished product uniformity is difficult to guarantee that production cost is also high, so this problem is discussed to be solved.
Summary of the invention
The utility model provides a kind of electric machine casing cold extrusion molding mould, makes electric machine casing mainly by cold extrusion machine-shaping, and it has not only solved the subject matter in the production at present of this part effectively, and the also obviously raising of its quality, and precision can reach micron order.
The utility model is achieved in that the electric machine casing cold extrusion molding mould comprises body of punch and die body, its punch is fixed in the patrix mould bases by the punch retainer plate, the die assembly is fixed in the counterdie mould bases by die retainer plate assembly, establishes push rod in the die bottom; Nose of punch and die assembly bottom is circular arc simultaneously.
Effect of the present utility model is that cost obviously reduces because part by the mould one-shot forming, becomes simple and convenient thereby make to produce, and environmental pollution reduces, and product quality is controlled easily.
Description of drawings
Accompanying drawing 1 is the structure cutaway view of the utility model electric machine casing cold extrusion molding mould.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the electric machine casing cold extrusion molding mould is made by die steel material, adopts existing mould making process to make, after throwing is ground, make up.The electric machine casing cold extrusion molding mould comprises body of punch and die body, and its punch 4 is fixed in the patrix mould bases 3 by punch retainer plate 2, and die assembly 7 is fixed in the counterdie mould bases 5 by die retainer plate assembly 6, establishes push rod 8 in the die bottom; Punch 4 heads and die assembly 7 bottoms are circular arc simultaneously.
When using, this mould is contained in the mould bases of forcing press, to pre-treatments such as part blank soften, make it have corresponding performance and dimensional accuracy, it is cold extrusion shaped to put into mould then, after fine finishining is made finished product after handling.
