鐵心片沖壓成形工藝及模具設計 摘要：本設計的題目是鐵心片的復合模具，通過對方案的選擇排樣的計算，沖壓力的計算和壓力中心確定的計算以及凸凹模刃口的計算等使本副模具基本符合沖壓要求。復合模具的精度要求很高導向要求十分精確，在設計本副模具時遇到很大的阻力經過對各方案的選擇和排除最終才選擇此方案。通過近三周的拼搏，本副復合模具設計終于完成。由于設計者的能力所限，設計中的不足之處還有好多。還有復合模具益后側導柱模架—《實用模具技術手冊》 ，本模具的沖裁力不大精度基本能保證的前提下選擇了中間導柱模架。相信不久本模具投入市場一定能帶來很好的效益服務大眾，服務社會。關鍵詞: 復合模 試沖 間隙配合 過渡配合 The compound die design of tiexinpian Abstract：Topic that design originally to compound die, 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.
