Single process model refers to only one station, only to plete the process of punching die, it can be divided into the blanking die, bending die, stretching mold, turn over the hole pattern and plastic mould etc. Single process model is a simple, precision stamping die, many advantages such as high precision and high service life, applicable to production of various kinds of stamping industry. Single process theories of stamping die, stamping technology and die design and manufacturing, and many key technologies in mould material. Therefore, from the aspects of technical prehensive study of single process model is very meaningful. Will support the connection plate is analyzed the design
