1. A cold stamping production process for an automobile torsion beam flange connecting seat is characterized by comprising the following steps:

(1) and 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) and blanking: designing and manufacturing a special left and right workpiece blanking die at the same time, and carrying out blanking processing on the cut strip materials on a punch press or a hydraulic press;

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

(4) 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;

(5) and cutting off: 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;

(6) punching and deburring: designing and manufacturing a special punching die, punching mounting holes and bolt holes on a left workpiece and a right workpiece on a punch press or a hydraulic press respectively, and then putting the workpieces 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 an automobile torsion beam flange connecting seat.

Background

Automobile torsion beam flange connecting seat is left connecting seat and right connecting seat respectively, designs respectively the preparation mould production, adopts one shot forming process, and the mould drops into for a long time, and it is many to occupy the equipment place, and the production cycle is long, and the management degree of difficulty is big, adopts one shot forming process, and the connection support after the shaping is not good with left and right beam welding that moves about freely and quickly, and the influence welding efficiency and welding quality are not well cooperated.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides the cold stamping production process for the flange connecting seat of the automobile torsion beam, 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 left and right workpiece blanking die at the same time, and carrying out blanking processing on the cut strip materials on a punch press or a hydraulic press;

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

4. 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;

5. cutting: 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;

6. punching and deburring: designing and manufacturing a special punching die, punching mounting holes and bolt holes on a left workpiece and a right workpiece on a punch press or a hydraulic press respectively, and then putting the workpieces 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 production efficiency, low cost, simple and safe operation, capability of well meeting the welding processing of the subsequent process, less occupied equipment, field and mould, high material utilization rate and popularization and application value.
