Trimming die

Design of back pressure plate

During the stamping process, the main action parts (punches, blanking plates, and female dies) will bear the surface pressure only after they are pressed. When the punching pressure is higher than the surface pressure, the back pressure plate (especially the back of the punches and female die sleeves) should be used. The back pressure plate can be used in both local and comprehensive ways.

Mold design software

Modern industry is developing very fast. It is basically designed and processed by computer, and its precision can be guaranteed to be 0.002~0.01. There is a broad field in mold design. If you can use computers to assist in design, your competitors will be invisible behind you Common mold design software includes AUTOCAD Pro/E UG SW CIMatron, mishiong, etc.

Impact on service life

Design is a key step in the production of die manufacturers and the initial link of production. It controls the whole process of die production. Therefore, design also has a great impact on the service life of dies. Design mainly affects the service life of stamping dies from the following two aspects.

(1) The precision of the guide mechanism of the die. Accurate and reliable guidance has a great impact on reducing the wear of working parts of the die and avoiding the gnawing of the male and female dies, especially the blanking die with no clearance and small clearance, the compound die and the multi station progressive die. In order to improve the service life of the die, it is necessary to correctly select the guiding form and determine the precision of the guiding mechanism according to the requirements of the process nature and the precision of the parts.

(2) Geometric parameters of die (male and female die) cutting edge. The shape, fit clearance and fillet radius of male and female dies have great influence not only on the forming of stamping parts, but also on the wear and life of dies. For example, the fit clearance of the die directly affects the quality of the blanking part and the life of the die. If the precision is high, the smaller clearance value should be selected in the design; On the contrary, the clearance can be appropriately increased to improve the service life of the die.
