The design is mainly directed against the rack frame tractor parts forming process carried out analysis and design process analysis based on two sets of forming mold, that is, compound die blanking punching and bending modulus. First of all, parts of the rack frame for the process analysis, to develop a reasonable program of the stamping process to determine its basic program for blanking punching - bending, and parts of the map to start the calculation; Secondly, the basis to proceed with plans, analysis the blanking process and layout, and edge blanking, bending and punch, die cutting and other mold components to design and calculate. Finally, according to previous results, using CAD software tool to compare the two sets of the overall charts and pictures from various parts.
After the calculation and analysis, we can know, can compound die and bending die can be created by the rack frame. The use of molds to create the parts, can improve productivity and reduce production costs, through the parts of the stamping die design, consolidate and deepen the knowledge, and achieved relatively satisfactory results.
Key words: rack frame composite mode bending modulus。
