摘 要
本设计进行了落料、冲孔、拉深复合模的设计。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。此外，本模具采用始用挡料销和钩形挡料销挡料。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。关键词： 复合模 校核 冲孔 落料 拉深。
Abstract
The design of the blanking and punching, drawing composite modulus design. This paper briefly outlined the Stamping Die current development status and trends. The product of a detailed analysis and the identification process. Stamping die design in accordance with the general steps to calculate and design the sets on the main mold parts, such as : punch and die. Punch plate, plate, Die plate and dump plates I. feet behind the sales, marketing and other derivative is. Die-standard model planes, to choose a suitable stamping equipment. Design work on the parts and specifications will press for the necessary checking calculation. In addition, the die block used only with marketing materials and Crook block behind the marketing materials. 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 workpiece 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 mass production requirements.
