Auto parts stamping dies generally have the following processes:

1. Drawing and forming

2. Trimming and punching (side trimming and side punching)

3. Flanging shaping (rollover)

Draw forming:: is a stamping process method that turns a metal flat blank cut into a certain shape into parts of various shapes under the action of tensile stress.

Drawing die design points:

1. Arrangement of pressure regulating pads Arrangement of pressure regulating pads

The adjustment pads are arranged close to the pressing surface, and each adjustment pad is arranged close to the pressing surface, one every 300~400;

Adjust the corresponding position of the pad, and set the pier block on the lower die; the corresponding position of the adjustment pad, pier block, and ejector rod should have vertical ribs.

2. A material locator should be set on the blank holder to ensure the stable placement of the sheets. A material locator should be set on the blank holder to ensure the stable placement of the sheets.

3. The guide plate at the end of the stamping die should be provided with anti-reverse. The form is that the left side of the stamping die guide should be set to prevent the reverse. The form is that the left side of the die is larger than the right guide position. The unilateral size is 10mm. 10mm.; a peep hole should be set at the guide plate. ; A peep hole should be provided at the guide plate.

4. A safety screw should be provided, and the length of the screw should ensure that the blank holder is at the top dead center.

There are 20 mm 20 mm gaps. gap.

5. There should be a safety protection plate between the blank holder and the lower formwork, and the height of the guard should be

Make sure that the blanking ring has a covering height of 30-30 mm when the blanking ring is at the top dead center. Cover height in mm.

6. Set the transport connection plate between the upper and lower molds. A transport connection plate is set between the upper and lower molds.

7. Mandrel arrangement requirements: evenly distributed around the parting line, so that the blank holder ring is subject to the mandrel layout requirements: evenly distributed around the parting line, so that the blank holder ring is subjected to stable force.
