Description

A kind of automobile drive axle housing body cuts long shedding mechanism

Technical field

This utility model belongs to machining equipment field, relates to a kind of shedding mechanism cutting long mould, particularly to one Plant automobile drive axle housing body and cut long shedding mechanism.

Background technology

The effect of automobile drive axle housing body is supporting and protects main reducing gear, differential mechanism and semiaxis etc..Meanwhile, it is gone back It is the key component of running gear, has together with propons (driven bridge) and bear the quality of automobile and during at running car, Bear each moment when counter-force, moment of flexure and braking that driving wheel transmits, and passed to the functions such as vehicle frame by suspension.Automobile drive Axle shell body can be divided into banjo axle and separable housing two class from structure.For adapting to bear driving wheel under different loads Moment, the profile of banjo axle is typically obform body in variable cross-section from two ends to center, and it uses upper and lower two often The mode of part axle housing splicing butt welding is made.

The traditional mode of production of axle housing is that point six procedures are processed, and it first uses single-point plate shearing machine to implement operation One blanking processing, secondly uses single-point enclosed steam-operating forcing press to implement the processing of operation two blanking, then uses single-point Closed Hydraulic Operation three processing and forming implemented by machine, then uses single-point enclosed steam-operating forcing press to implement operation four and cuts long processing, moreover uses single Point enclosed steam-operating forcing press implement operation five trimming processing, finally use radial drilling machine implement operation six hole (tapping) processing. Using traditional processing technology, its process is more, often runs the most smooth and easy because of workpiece loading or unloading operation more difficulty, discharging, Cause discharging process exception, cause production efficiency relatively low, produce the longest, it is important to owing to product orientation precision is the most accurate Easily causing the properties of product that profile is inconsistent and impact is to postwelding, therefore there is risk in the quality of product always.

This utility model is based on optimization property that in prior art, production technology exists and considers, a kind of axle housing of design is originally Body cuts long shedding mechanism, axle housing blank not only can be made to cut growth process stable, and product discharge process can be made smooth and easy, so Meet the long shedding mechanism of cutting of production axle housing, Improving The Quality of Products by designing a kind of energy, improve the production efficiency of product, Just seem the most necessary.
