Key points of automobile drawing die design
1. arrangement of adjusting pads arrangement of adjusting pads
The arrangement of adjusting pad is close to the pressing surface, one per 300~400 300~400 for each adjusting pad arrangement close to the pressing surface.
Adjusting pad corresponding position, the lower die set pier dead block; adjusting pad corresponding position, the lower die set pier dead block.
Adjustment pad, pier dead block, the corresponding position of the top bar should have a vertical bar. Adjustment pad, pier dead block, the corresponding position of the top bar should have vertical reinforcement. 2.
2. The material locator should be set on the pressure edge circle to ensure the stable placement of the board material. The material locator should be set on the crimping circle to ensure the stable placement of the sheet.
3. The guide plate of the end of the mold should be set to prevent reversal, in the form of the left side of the mold than the right side guide The guide plate of the end of the mold should be set to prevent reversal, in the form of the left side of the mold than the right side guide Position size Position size Y Y is 10mm larger to one side; peephole should be set at the guide plate
4. safety screws should be set, and the length of the screws should ensure that there is a 20 mm gap between the crimp ring and the upper dead center.
5. safety protection plate should be provided between the crimping circle and the lower template, and the height of the protection plate should be provided between the crimping circle and the lower template, and the height of the protection plate should ensure that the crimping circle has a 30 mm cover height when the crimping circle is at the upper dead point.
6. Transport connection plate is set between upper and lower die. Transport connection plate is set between upper and lower die.
7. Top bar arrangement requirement: evenly distributed along the die line, so that the crimping circle is subjected to the top bar arrangement requirement: evenly distributed along the die line, so that the crimping circle is subjected to stable force.
