What are the design elements of blanking die?
The design elements of blanking die include the following aspects:
1) precision and technical requirements of blanking pieces.In the design, the structure and form of the die should be considered first, so that the mold structure is simple, manufacturing and maintenance is convenient under the premise of ensuring the precision of the blanking pieces.
2) safe operation.The operation of the mould should be safe and easy to use.The design of the mould must meet the requirements of safety production, especially the feeding and discharging parts. It is necessary to have good safety measures, and the installation and disassembly structure of the die should also be convenient and reliable.
3) materials for stamping die.There are many kinds of mould materials and types, which should be considered according to the different requirements of the die, batch size and processing equipment.If the mold shape is suitable, the blanking part is large, the service life of the die should be considered, and the best use of hard alloy material.General mold requirements high hardness and high wear resistance, can choose silver - based die steel.Cr12, Crl2MoV, CrWMn.Hot die steel should be used for blanking die in hot state, such as 302W8V and 5CrMnMo.
