This time, a set of punching and blanking die was designed. After consulting the data, we must first analyze the process of the parts. After process analysis and comparison, we adopted the punching and blanking process, and determined the model of the press through the calculation of punching force, ejecting force and discharging force. Then, the die types suitable for stamping parts processing are analyzed, and the die that needs to be designed is selected. After obtaining the type of mold to be designed, express the design process of each working part of the mold.
The first part of the document mainly describes the development of stamping die, explains the importance of stamping die and the significance of this design, followed by the process analysis of stamping parts and the determination of process scheme. The second part, design the layout of parts and calculate the material utilization rate. Then, the calculation of blanking process force and the design and calculation of the working part of blanking die are carried out, which provides a basis for selecting stamping equipment. Finally, the design of main parts and the selection of standard parts provide a basis for designing the drawing and forming of the mold and the size of the assembly drawing. Draw the parts and assembly drawings of the mold through the previous design scheme.
This design expounds the structural design and working process of the stamping flip-chip compound die. The die has reliable performance and stable operation, which improves product quality and production efficiency and reduces labor intensity and production cost.

This design carries out the design of blanking and punching progressive die. This paper briefly summarizes the current development status and trend of stamping die. The product was analyzed in detail and the process scheme was determined. According to the general steps of die design, the main parts of this set of die are calculated and designed, such as punch, die, punch plate, pad, die, stripper plate, locating pin and so on. The standard die frame is adopted for the die, and the appropriate stamping equipment is selected. In the design, the working components and press specifications are checked and calculated. In addition, the mold adopts finger-shaped stop pins and hook-shaped stop pins. Punching and blanking punches are fixed to different plates respectively, so as to adjust the gap; The punching die and the punching die are fixed by an integral plate. The blanking punch is loaded by the locating pin, which ensures the relative position between the hole and the contour and improves the machining accuracy. This structure can ensure the reliable operation of the mold and the requirements of mass production.
