Integral extrusion forming method for asymmetrical assembly parts and apparatus thereof

Abstract

The invention relates to an integrated compress molding method of asymmetry integrated element. It uses concave and convex moulds, to heat, compress and mold the blank. It is characterized in that: according to the position and size of cam on the element, designing the blank with non-uniform thickness; the blank is arranged in the concave mould with a deflection as S; the thicker part of blank or the deflected part is arranged with the edge that needs more metal (the edge with cam); it controls the metal flux and flow direction, via said non-uniform thickness or the deflection amount S, to fill the mould chamber with metal to mold the element. The inventive mould is integrated, with stable operated and simplified process. The element can be compressed molded in one time, to reduce the producing cost; the product has high size and surface accuracy, and high material utilization.

Description

1. Technical field [0001] The invention belongs to metal extrusion forming technology, in particular to an integral extrusion forming method and device for asymmetric combined parts. 2. Background technology [0002] Asymmetric flanged disc-shaped parts are widely used in automobiles, petroleum industries and other fields (such as figure 1 Shown), at present, such parts are mainly manufactured by casting or forging mechanical cutting. Using extrusion process instead of traditional processing method to produce such parts can save raw materials, improve product quality and productivity, and it is a promising process. Especially for some parts with high performance requirements, the extrusion molding process can achieve the purpose of improving the comprehensive mechanical properties of the parts. The extrusion process of some symmetrical or regular flanged disc-shaped parts has been applied in production and has achieved good benefits. However, for asymmetric or irregular p...

AI Technical Summary

Problems solved by technology

However, for asymmetric or irregular parts with flanges, the extrusion molding is different from ordinary parts, and the metal flow is complicated; if multi-pass deformation is used, the high production cost is difficult to apply in engineering

At present, there are no relevant research reports at home and abroad, and it cannot be applied to actual production.
