The Reasons for Rebound In Metal Stamping Processing
What is Metal Stamping?
Metal stamping is a kind of processing method with high production efficiency, low material loss rate and low production and processing cost. So what are the stamping processes of metal stamping? Next, a China metal stamping manufacturer with 30 years of stamping experience will introduce the characteristics of metal stamping processing technology in detail:
- Metal stamping is a processing method with high production efficiency and low material consumption. Metal stamping process is mainly suitable for the production of large quantities of parts and components. It can be more convenient for mechanization and automation, and has higher production efficiency. In addition, stamping production can not only achieve less waste and no waste manufacturing, but even in some cases there are tailings, which can also be used reasonably.
- The operation method is easy to process and does not require staff to have a high level of craftsmanship.
- Most of the parts processed by metal stamping do not need to be machined and manufactured, and have high precision dimensional accuracy.
- Metal stamping has good interchangeability. The stability of stamping processing is better, and metal stamping parts of the same batch can be used interchangeably without affecting assembly and product performance.
- Since metal stamping mostly uses plate as material, its surface quality is relatively good, which creates convenient conditions for the next step of metal surface treatment process (such as electroplating, heat treatment).
Reasons for Springback in Metal Stamping Processing
What is Metal Stamping Processing Springback?
Springback means that the shape of the deformed body is partially restored when the load is removed. And the shape and size of the workpiece do not match the shape and size of the working surface of the stamping die, resulting in the size of the workpiece being out of tolerance and affecting the assembly accuracy of the product, which belongs to processing Forming defects that are difficult to overcome in the process.
The Reason Why Metal Stamping Occurs Springback
- Material properties
Stamping parts of different strengths, from ordinary plates to high-strength plates, different plates have different yield strengths. The higher the yield strength of the sheet, the easier it is to spring back. The material of the thick plate workpiece is generally a hot-rolled carbon steel plate or a hot-rolled low-alloy high-strength steel plate. Compared with cold-rolled thin sheet, hot-rolled thick sheet has poor surface quality, large thickness tolerance, unstable material mechanical properties. And lower elongation of the material.
- Material thickness
In the forming process, the thickness of the sheet has a great influence on the bending performance. As the thickness of the sheet increases, the springback phenomenon will gradually decrease. This is because as the thickness of the sheet increases, the materials involved in plastic deformation increase. And then the elastic recovery deformation Also increases, therefore, the rebound becomes smaller.
- Workpiece shape
The springback of workpieces with different shapes is very different. For workpieces with complex shapes, manufacturer generally add a sequence of shaping to prevent springback if the forming is not in place. And some special-shaped workpieces are more prone to springback, such as U-shaped workpieces. We need to consider Springback compensation when analyzing the forming process.
