自行车脚蹬内板冲压成形工艺及模具设计摘要：本设计题目为端盖落料拉深复合模设计，体现了带凸缘筒形零件的设计要求、内容及方向，极有设计意义。通过对该零件模具的设计，进一步丰富了本人冷冲模设计的基础知识，为今后设计更复杂的冲压模具做好了铺垫并获取了更丰富的经验。 本设计运用冲压工艺及模具设计的基础知识，首先分析了制件的形状及生产可行性，为合理选取冲压工艺方案做好准备；然后估算了落料毛坯的体积，便于排样；最后分析模具结构，确定模具的设计参数、设计要点及卸料装置的选取。本制件是带凸缘的筒形件，选择合适的压边力是极为重要的，它具体应在保证不起皱的前提下取最小值。卸料板在落料前兼起压料作用。 本复合模具先由凸凹摸与落料凹模进行落料拉深工序，后进行冲孔工序。此外，在排样的工作中力求板材利用率达到较高的水平。关键词：落料拉深复合模，浅拉深，拉深间隙，带凸缘筒形件 BICYCLE PEDAL PANEL STAMPING FORMING PROCESS AND DIE DISIGN Abstract：This design topic compound die for blanking and drawing ,design for the end cover, has manifested the belt flange tubular components design request, the content and the direction, has the design significance extremely.Through to this components mold design, further enriched myself to die coldly the design elementary knowledge, for will design the more complex ramming mold to complete the upholstery and to gain a richer experience from now on. This design the elementary knowledge which designs using the ramming craft and the mold, first has analyzed the workpiece shape and the production feasibility, prepares for the reasonable selection ramming craft plan; Then estimated fell the material semifinished materials the volume, was advantageous for a row of type; Finally analyzes the mold structure, definite mold design variable, design main point and dumping device selection. This workpiece is shaped part with flange, chooses the appropriate pressure-pad-force is extremely important, it should not take the minimum value specifically in under the guarantee corrugation premise.Unloads the yard lumber on to fall in front of the material concurrently to press the material function. This compound mold by convex-concave traces first with falls the material concave mold to carry on falls the material drawing working procedure, latter carries on the punch holes working procedure.In addition, makes every effort the plate use factor in the row of type work to achieve the high l
