焊片冲压成形工艺及模具设计(任务书,中期检查表,论文说明书10000字,工艺过程卡,CAD图10张)
摘 要
本设计题目为焊片冲压模具设计，体现了冲压零件的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了设计者冲压模设计的基础知识，为设计更复杂的冲压模具做好了铺垫和吸取了更深刻的经验。
本设计运用冲压工艺及模具设计的基础知识，首先分析了冲压件的尺寸及性能要求，为选取模具结构形式做好了准备；然后确定排样的方式；确定模具的设计参数、设计要点及推出装置的选取；根据前面计算出来的冲压力选取冲压机床。
该零件形状简单、对称。是由圆弧和直线组成的，冲裁件内外形所能达到的经济精度为IT12~IT13。孔中心与边缘距离尺寸公差为±0.5。将以上精度与零件的精度要求相以较比，可以为该零件的精度要求能够在冲裁加工中得到保证，其他尺寸标注，生产批量等情况，也均符合冲裁的工艺要求，故决定采用冲压方式进行加工该零件的圆角半径R=0.6≥0.18t=0.18×0.7=0.175符合要求。

Die welding sheet forming process and die design
Abstract
The topic for the solder-chip design stamping die design, stamping parts reflects the design requirements, content and direction of the design of a certain significance. Parts of the mold through the design, designers have further strengthened the basis for stamping die design knowledge, for the design of more complex stamping die to do a good job of paving the way and draw a more profound experience.
The design of the use of stamping process and die design of the basic knowledge, the first analysis of the size of stamping parts and performance requirements, in order to select the form of die structure ready; and then ranked to determine the kind of way; determine the mold design parameters, design features and the introduction of device selection; calculated in accordance with the red in front of select pressure punching machine.
The shape of the parts is simple, symmetrical. Is formed by the arc and a straight line, and blanking pieces can form within the economic reach an accuracy of IT12 ~ IT13. Center hole size and edge distance tolerance for ± 0.5. The above parts precision and accuracy requirements in order to per pound, you can request for the accuracy of parts in the stamping process can be assured that other dimension, such as production volume, but also are in line with the blanking of the technological requirements, it decided to adopt punching means for processing the parts of the fillet radius R = 0.6 ≥ 0.18t = 0.18 × 0.7 = 0.175 to meet the requirements.
Keywords: stamping die, the introduction of devices, the production of bulk
