Solar stamping parts unqualified reason: size and shape, stamping materials caused by springback is unqualified;
Locator wear deformation occurs, and make the article had no, must be replaced a new locator;
In undirected bending die, on the pressure adjustment, press the slider bottom dead center position adjustment is undeserved, can cause bending parts unqualified size and shape;
The mould pressure device failure or not enough material, have to readjust the force that press a material or replace the spring pressure to make it work.
Measures to reduce the solar stamping rebound: selection of the mechanical properties of the elastic modulus of the yield point small solar stamping parts stamping materials with steady;
Increase the calibration process, using the calibration curve instead of free bending;
Materials to be annealed before bending, make the cold work hardening material softening in advance before forming;
If the shape deformation occurred during stamping process and difficult to eliminate;
You should replace or repair the rake of convex die and concave die, and intensive gap is equal to the minimum material thickness;
Die and workpiece, the contact area decreases surface contact between the punch and artifacts;
30 years of experience in precision metal precision solar stamping parts stamping, stamping all kinds of precision metal terminals, stamping speed can reach 1500 SPM, high-precision solar stamping production with high efficiency.
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.
