Stamping parts are sheet metal parts, which can be processed by stamping, bending, stretching and other processes through metal stamping dies. The corresponding parts are casting parts, forging parts, machined parts, etc. with the rapid development of stamping technology, the requirements of manufacturing and machinery industry are continuously raised. Precision metal stamping dies are widely used in new energy, automation equipment, medical devices The development momentum of molds in aerospace, energy conservation and emission reduction and other product fields is strong.

Die is an important part of metal automobile stamping parts processing. The quality of metal stamping parts is basically determined by the quality of stamping die. In order to ensure the quality, service life and precision of the die, it is necessary to understand the hot working process and precautions of the metal stamping die.

Selection principle of stamping die:

1. First, consider the stamping die set under "select stamping die". For the set square die, analyze whether the straight line to be stamped is greater than or equal to 1.5 times the side length of the stamping die. When the circular die is stamping the inside of the curve, analyze whether the arc diameter to be stamped is greater than the die diameter. If so, use the set die.

2. For the contour that can be classified into the basic figure, first search the die library for whether there is a stamping die that is completely consistent with the contour and can be punched out of the contour with a stamping action. If there is such a die, the stamping die set under "select stamping die" will be ignored and the found stamping die will be used directly.

3. For the rectangular contour, when the long side is greater than or equal to 1.5 times of the short side, it will automatically search whether there is a square stamping die consistent with the short side of the rectangle. For the long circular groove or circular groove, it will search whether there is a circular stamping die with the same groove width. If there is a circular stamping die, it will be directly used. If the stamping die is not determined after the above two steps, it will be considered to use a square stamping die or a circular stamping die to step a straight line or arc.

4. If the set die is not appropriate, the system will search the square or circular die from small to large in the stamping die library, and use the straight line to be stamped that is greater than or equal to 1.5 times the side length of the die.
