加工转换支架复合模具设计

加工转换支架复合模具设计(含任务书,开题报告,毕业论文说明书8000字,cad图纸7张)
摘 要
本设计的题目是加工转换支架的复合模具，通过对方案的选择排样的计算，冲压力的计算和压力中心确定的计算以及凸凹模刃口的计算等使本副模具基本符合冲压要求。
复合模具的精度要求很高导向要求十分精确，在设计本副模具时遇到很大的阻力经过对各方案的选择和排除最终才选择此方案。通过近三周的拼搏，本副级进模具设计终于完成。。
由于设计者的能力所限，设计中的不足之处还有好多。还有复合模具益采用四角导柱模架—《实用模具技术手册》，本模具的冲裁力不大精度基本能保证的前提下选择了中间导柱模架。相信不久本模具投入市场一定能带来很好的效益服务大众，服务社会。

Mold design of the processing quartz form iron core  
Abstract： Topic that design originally to process quartz form compound die ,iron of core enter mould , rank the calculation of kind through the choice to the scheme, it makes this pair of moulds accord with the request of pressing basically to press calculation , calculation which the pressure centre confirm and calculation of the protruding concave mould blade of strength ,etc.,

compound die enter precision of mould expect very much and lead demanding to be very accurate, the obstruction that it is very great to meet while designing this pair of moulds is through and gets rid of and chooses this scheme to the choice of every scheme finally. Through the striving of nearly three weeks, this each enters mold design to finish at last.
The because designer one it restrict with ability, have much weak point in design. There is compound die that enters benefit of the mould and adopts four mao and leads the post mould shelf - " practical mould technical manual ", the blanking strength of this mould leads the post mould shelf the middle not quite choosing under the prerequisite that the precision can be guaranteed basically. Can unquestionably bring very good benefit and serve the general public to invest the market while believing a mould soon, serve the society.
