通孔帶凸緣 U形件的沖孔切邊復(fù)合模具設(shè)計【沖壓成型工藝及模具】 摘要：本設(shè)計的題目是加工沖孔切邊的沖壓復(fù)合模具，通過對方案的選擇，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，由于工件結(jié)構(gòu)簡單，采用復(fù)合模一次成形就可以實現(xiàn)零件的成形。復(fù)合模具的精度要求很高導(dǎo)向要求十分精確，在設(shè)計本副模具時遇到很大的阻力經(jīng)過對各方案的選擇最終才選擇此方案。通過近三周的拼搏，本副級進(jìn)模具設(shè)計終于完成。根據(jù)標(biāo)準(zhǔn)模架的選擇，制作凸凹模材料的選擇以及導(dǎo)向和送進(jìn)精度的確定本模具所加工出的工件滿足要求，符合市場的需要。由于設(shè)計者的能力所限，設(shè)計中的不足之處還有好多例如：材料利用率方面僅57%，會對經(jīng)濟(jì)效益有影響。根據(jù)《實用模具技術(shù)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對角導(dǎo)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(wù)大眾，服務(wù)社會。關(guān)鍵詞：復(fù)合模、壓力中心.Trimming Process punching and stamping die Abstract：This design is the subject of punching Trimming the processing of stamping die, through the choice of programme, the calculation of the pressure-pressure center and determine the terms and Tuao-edge computing, such as making the mold of the basic requirements of the press, as the workpiece Simple structure, forming a composite mode can be achieved forming parts. The accuracy of die-oriented requirements of very high precision, deputy die in the design of this encounter great resistance to the programme after the final selection was chosen this option. Jin Sanzhou through the struggle, the deputy Progressive Die Design finally completed. Standards moldbase in accordance with the choice of production Tuao-oriented, and the choice of material and taken to determine the accuracy of this mold by processing the workpiece to meet the requirements, in line with the needs of the market. As designers the ability constraints, the design of the inadequacy of the many there are, for example: utilization of materials in only 57 percent have an impact on economic efficiency. According to "die for a technical manual," the mold of punching power can not guarantee the accuracy of the basic premise of the choice of derivative---Kok. I believe the market will soon die of this will certainly be able to bring the benefits of serving the public good and serve the community.Key words: transfer mold、 pressure centre。
