0040-回油管夾片沖壓成形工藝及模具設計（倒裝沖孔落料復合模、彎曲模2套模具）【全套19張CAD圖】,全套19張CAD圖,油管,沖壓,成形,工藝,模具設計,倒裝,沖孔,復合,彎曲,曲折,模具,全套,19,cad 回油管夾片模具設計 摘要：本設計題目為回油管夾片成形工藝與模具設計，體現了板類沖壓零件的設計要求、內容及方向，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具設計的基礎知識，為設計更復雜的沖壓模具做好了鋪墊并吸取了更深刻的經驗。 本設計運用沖壓成型工藝及模具設計的基礎知識，首先分析了工件的成形工藝及模具成形結構對制件質量的影響。介紹了回油管夾片模具設計時要注意的要點，通過對制件進行工藝分析，可確定制件的成形加工用一套沖孔落料復合模和一套彎曲模。從控制制件尺寸精度出發(fā)，對回油管夾片模具的各主要尺寸進行了理論計算，以確定各工作零件的尺寸，從模具設計到零部件的加工工藝以及裝配工藝等進行詳細的闡述，并應用CAD進行各重要零件的設計。 關鍵詞：復合模；彎曲模；工藝分析；模具零部件的加工工藝。 Oil return pipe die design Abstract:The topic for the Oil return pipe die design reflect the sheet metal stamping parts of the design for the requirements content and the direction,Have a significance of the design.Through the design of the die parts to further enhance design of a oil return pipe enlarge the basic knowledge for the designer and put the way for the designer of more profound experience The design use the basic knowledge of the die design, First there is an analysis for the shape of the workpiece forming and die structure of the parts quality. Introducedthe key point of the oil return pipe design that we should be noted , Through the process of analysis for the die, we can identify the parts of the forming punch is a blanking die and a set of composite bending die.Size the precision parts of the control of the key point,and calculat of all the major theoretical I carried out the the size of the working parts、the parts from the mold design process and the assembly process,AndI carry out CAD to design important parts of the oil return pipe die. Key words:compound die; Blending dies；process analysis；processing of die parts
