Stamping parts of the light weight and thin thickness, good rigidity.Its size tolerance is depended by mold guarantee, so the quality is stable, generally do not need then through mechanical cutting can be used.Cold stamping metal organization and mechanical performance is superior to the original blank, the surface is smooth and beautiful.Cold stamping tolerance grade and surface state is better than that of hot stamping.
Large quantities of medium and small stamping parts production is generally adopted complex mold or multi-station progressive dies.In modern high-speed transfer press as the center, configuration with an open-book, correct, finished product collection, transmission and tooling libraries and quick die change equipment, and use the computer program control, can form high productivity of fully automatic stamping production line.Using new mould material and all kinds of surface treatment technology, improve the mould structure, can get high accuracy and life of the stamping die, so as to improve the quality of stamping parts and stamping parts manufacturing cost.
Stamping production process and equipment is developing unceasingly, in addition to the use of traditional press and steel mould manufacturing stamping parts, hydraulic forming and spinning forming, molding, explosive forming, electric water forming and electromagnetic forming and other special stamping forming technology is developing rapidly, the stamping technology level to a new height.Special stamping process is especially suitable for many kinds of medium and small batch production of (or even dozens) parts.For ordinary stamping process, can use simple mould, low melting point alloy mould, group stamping molds and flexible manufacturing systems, etc., organize many varieties of small batch parts stamping processing.
All in all, stamping with high productivity, low processing cost, high material utilization, simple operation, easy to realize mechanization and automation, and a series of advantages.Use the composite process such as stamping and welding, bonding, make the parts structure more reasonable, more convenient processing, can use a relatively simple process to create more complex structure.
