High-speed press molds for punching silicon steel sheets (silicon steel sheet EI sheets)

High-speed press mold for punching silicon steel sheet (silicon steel sheet EI sheet) in detail

      Punching silicon steel sheet (silicon steel sheet EI sheet), in the past are in the ordinary punching machine with general molds; with the demand for silicon steel sheet is getting bigger and bigger, higher and higher precision, the traditional production method has been unable to adapt to the requirements; more enterprises began to introduce high-speed punching machine and carbide molds to produce silicon steel sheet. Molds are consumables, imported molds imported molds are not only expensive, and long delivery cycle. At present, China's high-speed stamping industry, from imitation, to digestion, absorption, enhancement, has developed a high-speed press special carbide mold series: standard EI sheet molds from EI * 24 to EI * 105, non-standard meter molds, motor stator molds and so on. The performance of the molds is comparable with imported molds, the highest punching speed reaches 800 times/minute, the life span is 100 million times, the precision of the punched piece (especially flatness) is better than that of imported molds, and better economic and social benefits have been achieved.High Speed Stamping Machine

　　Cemented carbide material size is small, expensive, high hardness, difficult to process, molds for high-speed punching, must reach high speeds, so the mold design and manufacturing is different from ordinary punching general material molds, must be paid attention to.High Speed Stamping Machine
