电池压线圈冲压模具设计
摘 要
本次电池压线圈的设计共需要三套模具,第一套模具是电池压线圈的冲孔落料,采用复合模倒装结构;第二套模具是电池压线圈的U型弯曲;第三套模具是二次校正弯曲。在整个设计的过程中要计算冲孔,落料和弯曲的各个力,在保证模具各个部件在能承受压力机的作用下,使模具运行良好。
首先,本次设计叙述了冲压模具在发展领域中的作用和其发展的前途,以及冲压模具的分类和特点。其次,就是对工件的工艺分析,设计几个工艺方案,经过综合对比,来确定一个最好的工艺方案。然后,就是通过计算材料利用率来确定排样方案,算出冲载力、压力中心和凸凹模刃口尺寸的计算,及算出模具工作的尺寸公差并校核零部件尺寸,接下来要计算U型尺寸和二次校正尺寸,并要注意U型弯曲和二次校正弯曲所带来的中性层的偏移及板料变薄等问题。最后,模具类型的选择及总装配图的确定,及手绘一套装配图,及相应的零件图。

DESIGN OF STAMPING DIE PRESSURE COIL BATTER
ABSTRACT
The design of the battery voltage coil requires three sets of mould. The first set of mould is the battery voltage coil punching blanking compound die and uses the flip chip structure. The second sets of mould is U battery voltage coil bending. The second sets of mould is the second bending correction. Through the design process to calculate punching, blanking and bending stress in each process, it aims to guarantee every mould parts can bear under the function of each mold so as to ensure the good operation of the press .
First of all, this design is on the basis of the understanding the role of stamping die in the field of development and its development in future as well as the basis of classification and characteristics of stamping die . Secondly, it analyses the technology of the workpiece and the design of several process schemes. By a comprehensive comparison, we can choose the best process scheme. Then,we can calculate the material utilization rate to determine the layout scheme, the various technological force, pressure center ,the punch and die cutting edge size besides we need to pay attention to the mould dimension tolerance and check the size of components , the calculation of type U and the size of correction.We should also pay attention to the two correction offset and sheet metal bending neutral layer caused by the thinning problem U bending. Finally, We should determine the mold type selection and mold assembly and draw the corresponding mold parts.
