The design of automobile stamping die needs to consider many aspects, one of which is the consideration of actual production stability and maintenance on site. Today, let’s take a look at the mold state that has been mass-produced for a long time, and talk about the small details that we pay attention to in the design.
1.The design of automobile stamping die needs to consider many aspects, one of which is the consideration of actual production stability and maintenance on site. Today, let’s take a look at the mold state that has been mass-produced for a long time, and talk about the small details that we pay attention to in the design.
2. The design should fully consider the impact of lateral force on production stability.
As shown in the figure, it is the design drawing of flanging die for a mass production project. Because the flanging knife block is not designed with lateral force prevention device, the screw of flanging knife block is broken and the flanging knife block is loose in actual mass production, and the precision of the manufactured parts does not meet the requirements.
According to the actual mold space, an anti-lateral force stop was added to the side of the flanging block. After field batch verification, the screw of the flanging block did not break, and the precision of the parts met the requirements.
3. In the design, the mold must be supported by ribs under the bottom block.
As shown in the figure, the flanging shaping die of a mass production project was damaged because the four corners were not supported by reinforcing ribs at the lower part of the bottom block in the early design.
It was repaired and reinforced on site and a supporting rib was added to the lower part of the bottom block.
4. Fully consider the strength of the mold when designing.
As shown in the picture, the design thickness of the mold base of a mass production project is 30mm, and the mold is broken in the actual production process.
The conclusion of on-site observation and analysis is that the workbench of the production press has been bent and the die base is thin, which leads to the fracture of the die. On-site, a 60mm thick pad is added to the die base to resist the bending force. At present, there is no fracture in mass production.
