The eight process performance of precision stamping die

by:Fortuna     2021-02-03
Precision stamping mould manufacturing is typically after forging, machining, heat treatment, and a few procedure. In order to ensure the precision stamping die manufacturing quality, reduce production cost, the material should has a good malleability, cutting processability, hardenability, hardenability and grinding; Also should have little oxidation and decarburization sensitivity quenching distortion and cracking tendency. 1, malleability, have relatively low hot forging deformation resistance, good plasticity, forging temperature range wide, cold forging crack crack and precipitation carbide network tend to be low. 2, annealing craft: spheroidizing annealing temperature range wide, annealing hardness is low, and the fluctuation range is small, spheroidization rate is high. 3, cutting machining, cutting dosage, low dissipation of cutting tool and the processing surface roughness is low. 4, oxidation and decarburization sensitivity: when heated to high temperature oxidation bosom can good, decarbonization speed slow, is not sensitive to the heating medium, produce pitting tend to be small. 5, hardenability: after quenching is uniform and high surface hardness. 6, hardenability: after quenching can get deeper hardening layer, the ease of quenching medium can be hardened. 7, quenching deformation and cracking tendency: conventional quenching small volume change, shape warping, distortion, mild, abnormal deformation tend to be low. Conventional quenching cracking sensitivity is low, is not sensitive to quenching temperature and shape of the workpiece. 8, grinding, grinding wheel is relatively small loss, no burn limit grinding dosage, insensitive to the quality of grinding wheel and cooling conditions, grinding and grinding precision stamping die crack does not occur.
