Punching silicon steel (EI silicon steel sheet) of high-speed presses mold dwell

    SAMHOOR Tip: punching silicon steel (EI silicon steel sheet), in the past are in common with the general mold punch; with the growing demand for silicon steel, precision higher and higher, the traditional mode of production has not adapt requirements; more enterprises began to introduce high-speed presses and silicon carbide tooling. Molds are consumables, import mold imported mold not only expensive, but long lead times. At present, China high-speed stamping industry, from imitation, to digest, absorb, improve, has developed a dedicated high-speed presses carbide die Series: standard lens mold from EI EI * 24 to EI * 105, non-standard meter mold, motor stator rotor mold. Performance and imported mold mold rather, the highest red speed reaches 800 beats / minute, the life one hundred million times, punching accuracy (especially flatness) than imported mold, and achieved good economic and social benefits.

Small size carbide material, expensive, high hardness, difficult process, a mold for high-speed presses, must achieve high-speed, so different from the ordinary mold design and manufacture mold punch general material, it must be paid.
