支撐盤沖壓模設計 摘要:該設計題目為支撐盤沖壓成形工藝及模具設計，體現(xiàn)了盤類沖壓零件的設計要求、內(nèi)容及方向。有一定的設計意義，通過對該零件模具的設計，進一步加強了設計者沖壓模設計的基礎知識，為設計更復雜的沖壓模具做好鋪墊和吸取了更深刻的經(jīng)驗。本設計運用沖壓成型工藝及模具設計的基礎知識，首先對零件進行工藝性分析，以確定沖壓工序，然后計算零件的體積，便于選取合適的壓力機，最后分析了零件的特征，確定模具的設計參數(shù)、設計要點及卸料裝置的選取。本沖壓件的外緣和內(nèi)孔均為圓形，所以在設計模具結(jié)構(gòu)時，應考慮內(nèi)孔與外緣的相對位置精度。又由于零件需要拉深，所以復合模是首選，其工序即為：沖孔、落料、拉深。模具的設計中，設計凹模是關(guān)鍵，結(jié)合本副模具及零件的特點，剛性推件裝置是比較合適的選擇。關(guān)鍵詞：沖壓模 復合模 凹模Disk die design Abstract:The requirement ，content and direction of the design of the disk stamp parts are embodied on this pressing die design of the stamp parts of dam disk. The designer’s foundation knowledge of the stamp mould design is reinforced and is able to design more complex stamp mould through the design. Through the foundation knowledge, firstly, the processibility of the part is analyzed to determine the process of the stamp. Secondly, the volume of the part is computed to choose the pressing machine. Lastly the character of the part is analyzed to determine the mould design parameter and design point and choose the shedding mechanism.The pressworked part`s outer edge and internal hole are all circular.So when design the mold structure ,should consider the precision of relative position of the hole and the outflow boundary. Also because the part should be drawed, so,the compound die is the first choice.Its working procedure is:blanking、drawing、punched hole.In the mold design,the design of the equipment of pushing part is the key.Combing the characteristic of this mold and the part,the rigidity die is a comparatively appropriate choice.Keywords:Pressing die Compound die Die
