筒形件沖壓成形工藝與模具設計
摘 要 : 此次設計為落料—拉深—沖孔復合模，設計本模具充分利用了網(wǎng)上資源，圖書館藏書，更重要的是老師的諄諄教導，才成就了此模具。
在模具的設計過程中，首先，簡要地概述了沖壓模具的特點和在社會發(fā)展領域中的作用及其以后的發(fā)展前途，點明了模具的設計意義；其次進行工件的工藝分析；進而確定了工藝方案，計算出了模具工作部分的尺寸公差，設計出零部件，然后依據(jù)設計要求選擇各個標準件，最后設計出模具的總裝配圖。在設計過程中需要計算沖壓力，落料力，拉深力及推件力，卸料力，從而判斷模具各部件是否能承受壓力機的作用，更重要的是模具工作零件的設計，以此為核心的問題，工作零件的誤差將直接影響制件的質量。最后利于繪圖工具AutoCAD制作了裝配圖和零件圖，而節(jié)省了許多時間。
通過此次設計使我不僅掌握了沖壓模具設計的一般流程，更好的學習好多在課本上沒有學習的知識。
關鍵詞 : 沖孔,拉深,計算機繪圖,工藝分析

FORMING TECHNOLOGY AND DIE DESIGN
ABSTRACT :This time design for fall to anticipate- pull deep- blunt bore compound mold, design originally the molding tool made use of the on-line resources well, the library library, the more important teacher earnestly instruct, just achieving this molding tool.
In the design process of the molding tool, first, the synopsis ground says to hurtle the characteristics of press the molding tool all and after society develop the function in the realm and it of development prospect, order the design meaning of understand the molding tool;Carry on the craft analysis of the work piece the next in order;Then made sure the craft project, compute the molding tool work the size business trip of the part, design zero partses of, then request to choose the each standard piece according to the design, designing a total assemble diagram of molding tool finally.The demand computes the blunt pressure in design process, falling to anticipate the dint, pulling the deep dint and pushing a dint, unloading to anticipate the dint, thus judging whether each parts of molding tool can bear the function of the pressure machine or not, the design of the more important molding tool work spare parts, with this for core of problem, the error margin of the work spare parts will affect the quantity of make the piece directly.Finally the benefit manufactures to assemble the diagram and the spare parts diagrams in the painting tool .
Pass this time design make me not only controled to hurtle the general process of press the molding tool design, the better study is a lot of in the lesson originally up have no knowledge of study.
KEY WORDS: Blunt bore ,Pull deeply ,The calculator painting,The craft analysis
