Application of the torque equilibrium method in the study of offset displacement in the upper and lower dies in a shearing-cut progressive die

摘要

A shearing-cut progressive die is formed by arranging two or more sets of independent engineering dies in various engineering stations. The design of the shearing-cut progressive die involves a large number of Variables. For example, the confirmation of the pressure centre of the Shearing-cut progressive die is an issue worthy of exploration and evaluation. In this paper, we use the torque equilibrium method of the upper and lower Dies of the shearing-cut progressive die along both sides of the centre axis To derive the pressure centre position of the shearing-cut progressive die.
