设计的冲压件必须满足产品使用和技术性能，并能便于组装及修配。
(1) The stamping parts designed must meet the requirements of product usage and technical performance, and can be easily assembled and repaired.
⑵设计的冲压件必须有利于提高金属材料的利用率，减少材料的品种和规格，尽可能降低材料的消耗。在允许的情况下采用价格低廉的材料，尽可能使零件做到无废料及少废料冲裁。
(2) The stamping parts designed must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. In the case of permissible use of low-cost materials, as far as possible to make parts without waste and less waste blanking.
⑶设计的冲压件必须形状简单，结构合理，以有利于简化模具结构、简化工序数量，即用最少、最简单的冲压工序完成整个零件的加工，减少再用其他方法加工，并有利于冲压操作，便于组织实现机械化与自动化生产，以提高劳动生产率。
(3) The stamping parts designed must be simple in shape and reasonable in structure, so as to simplify the die structure and the number of working procedures, that is, to complete the whole part www.biaozhigan.net.cnwww.diandongmenc.cnwww.fenshaolu.net.cnwww.fenshaolu.org.cnprocessing www.zjkdiandongmen.cnwww.xinhaodenggan.cnwith the least and simplest stamping process, reduce the re-processing by other methods, and be conducive to stamping operation, facilitate the organization of mechanized and automated production, and improve labor productivity.
⑷设计的冲压件，在保证能正常保定平面设计培训 保定室内设计培训 保定空调移机 保定太阳能维修 保定厨房排烟 雄安管道通风 使用情况下，尽量使尺寸精度等级及表面粗糙度等级要求低一些，并有利于产品的互换，减少废品、保证产品质量稳定。
_The stamping parts designed in this paper, in order to ensure the normal use of the stamping parts, try to make the size accuracy and surface roughness level requirements lower, and is conducive to product interchange, reduce waste products and ensure product quality stability.
