设计简介
摘要：冲裁是利用冲模使部分材料或工序件与另一部分材料、工（序）件或废料分离的一种冲压工序。冲裁是切断、落料、冲孔、冲缺、冲槽、剖切、凿切、切边、切舌、切开、整修等分离工序的总称。冲孔是将废料沿封闭轮廓从材料或工序件上分离的一种冲压工序，在材料或工序件上获得需要的孔。
本设计进行了落料、拉伸复合模和单工序冲孔模具的设计。文中简要概述了冲压模具目前的发展状况和趋势。对产品进行了详细工艺分析和工艺方案的确定。按照冲压模具设计的一般步骤，计算并设计了本套模具上的主要零部件，如：凸模、凹模、凸模固定板、垫板、凹模固定板、卸料板、导尺、挡料销、导正销等。模架采用标准模架，选用了合适的冲压设备。设计中对工作零件和压力机规格均进行了必要的校核计算。模具的冲孔和落料凸模分别用不同的固定板固定，便于调整间隙；冲孔凹模和落料凹模则采用整体固定板固定。落料凸模内装有导正销，保证了工件上孔和外形的相对位置准确，提高了加工精度。如此设计出的结构可确保模具工作运行可靠和冲压产品大批量生产的要求。

Abstract: Die Blanking is to use some of the material or process conditions and other materials, processes or pieces of waste separation of a stamping process. Blanking is Cut-off、Falls the material、Punch holes、Flushes lacks、Flushes the trough、Splits cuts、Splits cuts、The chisel cuts、Cutting edge、Cuts the tongue、Incision、Renovation and other separation processes known. Punch will be closed along the contour waste materials or processes from the isolated pieces of a stamping process, the materials or processes obtained on the needs holes.
The design of the loading material, tensile modulus and single composite processes Piercing Die Design. This paper briefly outlined the Stamping Die current development status and trends. Identify the product of a detailed analysis and the process. Stamping die design in accordance with the general steps to calculate and design the sets on the main mold parts, such as: Terrace die、Cavity die、Punch-holder、Dunn age、Die holder、Stripper、 Jig、Pin stop、Pilot and so on. Die-standard model planes, to choose a suitable stamping equipment. Design work on the parts and specifications will press for the necessary checking calculation. Punch and Die blanking punch were different plate fixed to facilitate adjustment gap; Punch and Die blanking die is used overall fixed plate. Blanking punch contents is a derivative sales, and guarantee the work piece and the shape of the holes in the relative position accurately, improve processing accuracy. So the structure is designed to ensure reliable operation of die stamping products and the requirements of large-scale production.
