What is stamping?What are the three elements of stamping?
Stamping is a kind of metal plastic processing method, the billet is mainly plate, strip, pipe and other profiles, use the function of stamping equipment by mould, make the spare part I needed to get in shape and size.
Materials, molds and equipment are three elements of stamping.
The stamping process requires that the processed materials have higher plasticity and toughness, lower refractive ratio and aging sensitivity, and generally require that the elongation of carbon steel is greater than or equal to 16%, and the ratio of the strength of the steel is less than or equal to 70%.Low alloy high strength steel is greater than or equal to 14%.Otherwise, the stamping forming performance is poor, and certain measures must be taken to improve the manufacturing cost of the parts.
Mould is the main process equipment of stamping.The surface quality, dimension tolerance, productivity and economic benefit of the stamping parts have great relationship with the mold structure.The stamping die is divided into three parts: simple die, multi-process progressive die and composite die.
The stamping equipment mainly has mechanical press and hydraulic press.In mass production, high speed press or multi-station automatic press should be used.In the small batch production, especially the large plate stamping parts production, the hydraulic press.
