Description

technical field

[0001] The invention relates to the field of stamping and forming, in particular to a stamping multi-station die for medium-sized parts of automobiles. Background technique

[0002] Automobile body-in-white parts are mostly stamping parts. After the structural design of the stamping parts is determined, the economy of its processing should be fully considered to minimize the cost of stamping parts. The cost of stamping parts usually includes blank sheet cost, stamping cost, mold tooling amortization cost, etc. In most factories, external conditions such as equipment, personnel, and materials are basically unchanged for a certain period of time, but to reduce the cost of stamping parts, it is mainly from the rational arrangement of the stamping process.

[0003] Taking automobiles as an example, the length of stamping parts for automobile body-in-white is generally within 3 meters, and the length of parts with more than 60% (weight) of body-in-white is mainly...
