Because the mould industry contributes to the progress and development of the whole industry. By the time of the mould design and further develop and I want flexibility in the use of various disciplines of knowledge, with an open mind to learn an apply the theoretical knowledge to solve the practical problems encountered in the life. Punching is a kind of pressure process method that punching dies are used in press sheet to put pressure on the plastic deformation or separation, for a certain shape and size of components. The design of this course is plate stamping process and mould design, whose material is number 08 F, .two working procedures are carried out to achieve it. Procedure one is to cutting the working material; procedure two is to punch holes. two procedure adopt punched hole and cutting the working material. a good solution to the conventional stamp out the process design molds in its roots, the cost of production and high efficiency is lower, the actual production of a guiding role. The contents of this paper include progressive die and bending die row sample design, mould design , cutting force calculation , selection of punching mechanism , a pressure center, and carefully calculated whether or not to meet the requirements of the various part
