Design of Forming Process and Multi-Position Progressive Die for the Side Bending Support
Abstract: This design using Auto CAD 2008 as the software, support of lateral bending forming process and design of the multi position progressive die. The design of punching, bending, cutting off the progressive die design. In this paper, a brief overview of the present status and developing trend of stamping die. The products were identified with the process of analysis and solution. The paper first briefly summarizes the background and significance of the design,then expounds the analysis to determine the product of the process and process scheme,calculation of the size design of the main die parts, calculation and design of the main components of this set of mold, such as: punch, die, punch plate, plate, stripper plate, a tension spring, stop pin, guide pin etc.. Die standard model planes, to choose a suitable stamping equipment. Design work on the parts and specifications will press for the necessary checking calculation.
Key words: Progressive die; stamping equipment; punching; bending; cut off
