[Abstract] this design topic down tube liner tube blanking punching parts, material for theQ235, thickness of 1.0mm, belongs to the large scale production, precision IT10. The main content of this article is to analysis its process and the design of the stamping die.According to the structural characteristics of the parts and materials for the characteristics of the process of analysis and calculation, and further determines the process scheme.Determine the process scheme, selection of blanking punching compound die; then according to the technological calculation of die structure and the specific required each part design and selection, through the calculation of the needed force, primaries with press for the inclinable bench press J23-40, its nominal pressure 400KN; finally on the computer using the CAD drawing software draw all the assembly drawing and parts drawing, and label each components size, technical requirements and manufacturing standards.The design process with reference to various literature and technical standards.
