Common problems when hardware stamping parts deep drawing production, tell you 3 PM technique
Metal stamping parts can be seen everywhere in our daily life, the application is very wide, each production manufacturer in production will also meet some problems large and small, small today, the authors will summarize the peacetime accumulated experience tells us, to avoid similar problems.
Metal stamping parts in deep drawing in common a few questions: 1.
Shape and size discrepancy: because when design blank positioning is not accurate, or because the raw material problems result in artifacts rebound;
Should be adopted when designing a reliable way to reduce springback and finishing the mold to improve positioning accuracy;
Surface strain: the first reason may be improper material selection, material surface finish is poor, the other may be because the mould is not smooth, the design process is not reasonable cause;
Bending crack: first, the raw material texture direction may do not agree with the design layout can lead to crack;
Second, poor material plasticity, partial hard will cause cracking;
Third, the process design is unreasonable, cause mould and parts gap is too small, feeding difficulties lead to cracking and other solutions: 1.
Metal stamping parts in the design of a forming, as far as possible when drawing die design is symmetrical, positioning accuracy;
Select suitable materials for deep drawing 3.
Layout plan design, a scheme to buy raw materials, comply with the scope of deep drawing;
Deep drawing parts or flange part at the bottom of the hole edge and the side gap is reasonable, the side slope, the original Angle of reasonable radius arc;
