One Stop Solution Manufacturer for all kind of Stamping Products and CNC lathed products.
Stamping die heat treatment deformation occurred
Stamping die steel in a certain direction of the distribution of the existence of uneven carbide, carbide expansion coefficient is smaller than the steel matrix was about 30%, heating it prevent mold inner hole expansion, cooling and prevent mold inner hole shrinkage, uneven deformation in the mold inner hole, make the mould of the round hole appear oval. one The influence of the mould material ( 1) In manufacturing complex mold, try to choose smaller steel carbide segregation ( 2) To exist serious segregation of carbide die steel, must carry on the reasonable forging, to break the carbide crystal block, reduce the uneven distribution of carbide grades, eliminate the anisotropic properties ( 3) After forging die steel, must carry on the tempering heat treatment, give the equal distribution of carbide, tiny and dispersion of sorbite group 2. The influence of die structure design 1. Throughout the cause of the deformation due to the mold thickness or shrill rounded corners, therefore, when quenching cause thermal stress and organization stress between each part of the mould is different, lead to the expansion of the volume of each part is different, make the mold after quenching distortion. 2. Prevent method when designing moulds, in meet the need of actual production situation, should try to reduce the mold thickness disparity and asymmetric structure, in addition, the thickness of the stamping die, by adopting the structure design of smooth transition as soon as possible. Twenty years of experience in stamping die design team of engineers, break through the stamping industry technical difficulties, but production mould automatic riveting pieces, automatic mould tapping parts, precision stamping mould injection terminals, etc. Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
