(3) and forming: designing and manufacturing a special forming die, and simultaneously forming and processing a left workpiece and a right workpiece on a punch press or a hydraulic press;

(4) and separation: designing and manufacturing a special cutting die, and cutting and separating a left piece and a right piece on a punch press or a hydraulic press;

(5) punching and notching: designing and manufacturing a special punching and notch punching die, and respectively punching mounting holes, bolt holes and notches on a left workpiece and a right workpiece on a punch press or a hydraulic press;

(6) and deburring: and respectively putting the left workpiece and the right workpiece into a sand roller or a shot blasting machine for deburring.

Technical Field

The invention relates to a production method of automobile parts and components, in particular to a cold stamping production process of a lower plate of a cross beam of an automobile torsion beam.

Background

Automobile torsion beam crossbeam hypoplastron divide into left part and right part, adopts simple and easy mould production usually, and the hand forming has complex operation, and workman intensity of labour is big, and production efficiency is low, and manufacturing cost is high, and left part and right part are produced respectively in addition, occupy equipment, place many, and material utilization is low, and production cycle is long, and the management degree of difficulty is big.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides the cold stamping production process for the lower plate of the cross beam of the torsion beam of the automobile, which has the advantages of no need of occupying too many dies, equipment and fields, good shape and size consistency, simplicity, convenience and safety in operation, high production efficiency and low cost.

In order to realize the purpose, the specific process method adopted by the invention comprises the following steps:

1. blanking: combining the left and right workpieces to arrange samples according to the expansion sizes of the left and right workpieces, and shearing the plate into strips by using a plate shearing machine;

2. blanking: designing and manufacturing a special blanking die, and simultaneously carrying out blanking processing on the cut left and right workpiece strips on a punch press or a hydraulic press;

3. forming: designing and manufacturing a special forming die, and simultaneously forming and processing a left workpiece and a right workpiece on a punch press or a hydraulic press;

4. separation: designing and manufacturing a special cutting die, and cutting and separating a left piece and a right piece on a punch press or a hydraulic press;

5. punching and notching: designing and manufacturing a special punching and notch punching die, and respectively punching mounting holes, bolt holes and notches on a left workpiece and a right workpiece on a punch press or a hydraulic press;

6. deburring: and respectively putting the left workpiece and the right workpiece into a sand roller or a shot blasting machine for deburring.

By adopting the process method, the invention has the advantages of good product shape and size consistency, high qualification rate, high production efficiency, low cost, simple and safe operation, capability of well meeting the welding processing of the subsequent process, less occupied equipment, fields and moulds, high material utilization rate and popularization and application value.
