This paper introduces a reliable and practical sample forming method. Firstly, the external dimensions of the workpiece are calculated according to the workpiece drawing, and then the central pressure point is located. Considering the utilization of materials, draw a layout. Analyze the outline and specific size of the workpiece, and punch it with the compound die. It has high efficiency and simple manufacture. After the parameters are determined, the assembly of the die and the design and assembly requirements of the main parts are analyzed. In addition to design work instructions, assembly drawings. It also includes molds, non-standard parts drawings, processing drawings, processing cards and non-standard parts processing cards.
