Abstract: A three-dimensional(3D) model of the shoe toe is established by the CACX and UG software in this paper. Then the process analysis and calculations of the product are done with DYNAFORM software. The most reasonable technology scheme and the related die construction are determined in the end.

Abstract: Abstract. Based on the development of blanking of steel plate in automobile industry, design features and manufacturing technology of the blanking die of thick steel plate has been described in this article. And then, according to the production, the selection of the clearance between core plate and cavity plate of the blanking die of thick steel plate has been introduced. In addition, assemblage, adjusting steps and fault treatment of blanking die of thick steel plate has been recommended, so has the breakdown types and its elimination of the blanking die of thick steel plate during the initial stage of process.

Abstract: At present, the flange drawing part with bottom hole is produced by at least 2 sets of dies and not qualifies for modern manufacture concept. In this paper, a compound die is designed which the flange drawing part can be blanked, drew, punched and trimmed in the same forming-position. The die is made of tow convex and concave dies, one drawing female die, one punching die, one blanking female die and one trimming punch. One of the convex and concave is used to blanking, the blank is drew by drawing female die and the other convex and concave, the punching die is applied to punch the bottom hole, the edge of blank is cut by trimming punch. Beside, the key design points and working process of the compound die were discussed as well.

Abstract: Traditional stamping process of civil low-pressure vessel deals with blanking, drawing, trimming and flaring process in different processing station separately, work-piece transmission between different processing stations increases the auxiliary time, and the work-piece needs reinstallation, reduce production efficiency and increase production cost. In order to overcome the above disadvantages, the optimized stamping technology process is designed, compress four process (blanking、drawing、trimming and flaring) into a integrity process, and the development of a "4 in 1" stamping compound dies, that makes stamping automation realize easily, improve processing efficiency, easy operation, and reduce the product processing cost and labor costs, and enhance economic performance.
