What are the factors that determine the service life of press brake die?

The rationalization of die structure is the reason to improve the upper limit of die load and reduce the level of thermomechanical load.

Whether the treatment of section size change is reasonable will directly lead to the service life of the die.

What are the factors that determine the service life of bending machine die?

Pay attention to the possible defects in processing technology and the impact of bearing capacity during operation caused by the quality of die materials, and take necessary measures to make up for the deficiency of metallurgical quality, so as to improve the service life of die.

The defects in the machining process, pretreatment, forging, quenching and hardening and surface treatment of parts will have a significant impact on the wear resistance, anti bite ability and anti fracture ability of the die.

For example, defects such as die surface roughness, residual knife marks, micro cracks in EDM, surface carburization and decarburization during heat treatment will affect the bearing capacity and service life of the die.

When the die is working, the accuracy and stiffness of the equipment, lubrication conditions, pretreatment status of the processed materials, preheating and cooling conditions of the die will affect the life of the die.

The surface quality state, material hardness, elongation and other mechanical properties of the machined parts, and the dimensional accuracy of the machined parts are directly related to the die life.

The above factors are the reasons that affect the service life of the press brake dies.
