Stainless steel stamping mold burst cause analysis
Small to popularize the author before mould 3 big problems, today for everyone to spread out the reason for the stainless steel stamping mold burst and analysed, the usual cause of mold burst points the following categories: 1.
Stainless steel stamping mold problem of raw materials, the material of the itself is not good, easy to crack in the process of production;
Mold heat treatment process: mold heat treatment quenching tempering temperature control is not good, the first it is prone to deformation, the second easy cracking scrap;
Stainless steel stamping mould in billet grinding plane are not up to standard size, deformation;
Process and mould design, mould design strength is not enough, die clearance design is unreasonable, even die template to cut corners, without plate, and so on and so forth;
Wire cutting processes improper, thread cutting, thread clearance to do clear Angle;
Selection of press: press was not chosen when designing products for accurate, inappropriate in tonnage punch, cutting force is too large, or not enough adjustable die blanking force under too deep;
Blanking and blanking die no leakage of material to assembly or blocked, the plate plugging material;
Stripping, mold production did not do before demagnetization, production has broken needle etc card;
Staff awareness, the production staff rushed, mould positioning installation does not reach the designated position, material use air gun to blow out, mold plate crack still use;
More than 9 are stainless steel stamping moulds are prone to cracking, whether in the mold production or in production, should pay attention to, avoid the loss.
