Causes of Bending Die Damage or Cracks

May. 04, 2017


The factors that may cause damage to press brake tooling in the development, production and use are listed as follows:

①Material: if the material is not good, it is easy to break in the subsequent processing;

②Heat treatment: quenching and tempering process is improper, will produce deformation;

③Production: mold grinding flatness is not enough, produce deflection deformation;

④Design process: the strength of the mold is not enough, the distance between the knife edge is too close, the mold structure is unreasonable;

⑤Line cutting: line cutting processing is improper: pull line cutting, the gap is wrong, did not make clear Angle;

⑥Forming equipment: the size of the tonnage of the punch, the size of the punching force, the mold is too deep;

Production: the position of the upper and lower die of the bending machine mold is not adjusted to the specified place.

Our unique ability to provide our customers with virtually any complex and customized tooling enables us to recommend to our customers with the most cost-effective solu-tion to their sheet metal processing.
