The side holes are not easy to draw and deform during production and processing, the shape and size consistency of products is good, the operation is simple, convenient and safe, the production efficiency is high, the material utilization rate can be improved, the investment of a die and equipment is reduced, the production efficiency is high, the cost is low, and the method has popularization and application values.

Description

Cold stamping production process for lower plate of front cross beam of automobile
Technical Field
The invention relates to a processing technology of automobile parts, in particular to a cold stamping production technology of a lower plate of an automobile front cross beam.
Background
At present, in the production process adopted by the lower plate of the front cross beam of the automobile, three side holes are punched before the process of trimming and punching mounting holes in the machining process, the side holes are easy to deform when the trimming and punching mounting holes are punched, so that the shapes and the sizes of the side holes are changed, the positions and the shapes of the produced workpieces are poor in consistency, and the design requirements cannot be met.
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 front cross beam of the automobile, which is not easy to deform the side holes during processing, has good consistency of the shape and the size of a product, high material utilization rate, high product qualification rate, high production efficiency and low cost.
In order to realize the purpose, the invention adopts the following process steps:
1. blanking: shearing a steel plate into strips by using a plate shearing machine according to the unfolding size of the workpiece;
2. blanking and punching process holes: designing a special blanking and punching die, and carrying out blanking and punching process hole machining on the cut strip materials on a punch press or a hydraulic press;
3. forming: designing and manufacturing a special forming die, and forming and processing the plate materials which are blanked and punched with the process holes on a punch press or a hydraulic press;
4. trimming and punching: designing and manufacturing a special trimming and punching die, and trimming and punching the formed semi-finished workpiece on a punch press or a hydraulic press;
5. punching three side holes: designing and manufacturing a special side hole punching die, and respectively punching side holes on the formed semi-finished workpiece on a punch press or a hydraulic press;
6. shaping: designing and manufacturing a special shaping die, and shaping and processing the workpiece with punched side holes on a punch press or a hydraulic press.
By adopting the processing method, the side holes are not easy to draw and deform during production and processing, the product has good shape and size consistency, simple, convenient and safe operation and high production efficiency, can improve the material utilization rate, reduce the investment of moulds and equipment, has high production efficiency and low cost, and has popularization and application values.
Detailed Description
1. Shearing a steel plate into strips by using a plate shearing machine according to the unfolding size of the workpiece;
2. designing a special blanking and punching die, and carrying out blanking and punching process hole machining on the cut strip materials on a punch press or a hydraulic press;
3. designing and manufacturing a special forming die, and forming and processing the plate materials which are blanked and punched with the process holes on a punch press or a hydraulic press;
4. designing and manufacturing a special trimming and punching die, and trimming and punching the formed semi-finished workpiece on a punch press or a hydraulic press;
5. designing and manufacturing a special side hole punching die, and respectively punching side holes on the formed semi-finished workpiece on a punch press or a hydraulic press;
6. designing and manufacturing a special shaping die, and shaping and processing the workpiece with punched side holes on a punch press or a hydraulic press.
