U型槽模具在工作过程中,在循环应力的长期作用下,会导致疲劳断裂,U型槽模具要有一定的抗疲劳能力。

During the working process of the U groove die, the fatigue fracture can be caused by the long-term action of cyclic stress, and the U groove die should have certain anti fatigue ability.

U型槽模具的耐磨性取决于钢材的化学成分和热处理硬度,因此提高模具的硬度有利于提高其耐磨性。

The wear resistance of the U groove die depends on the chemical composition of the steel and the hardness of the heat treatment. Therefore, the improvement of the hardness of the mold is beneficial to the improvement of its wear resistance.
