Wear Resistance evaluation of punching process in Bani Walid Industrial Factory

الملخص

Abstract: The process of punching has become prominent in the manufacturing industry because of its ability to make highly specialized parts that minimize waste and cost. With punching process, the goal is to use what is stamped/punched out rather than what is left after going through the die. In this paper, the evaluation of wear resistance and productivity of cutting die that uses to make holes in gun safety part is discussed and studied. The results of this work showed that, there is attempts by some engineers in the factory to teach a high productivity of the die, but they failed, Where the dies used had many problems, including the decrease in the toughness of the punch, and an error in the design of the punch, To solve the problems that occur in the die, which were the reason for reducing productivity, we suggest choosing other wear-resistant materials to design new dies and making a suitable design for the die by applying the shear angle and suitable clearance between the bunch and the die.
