摘要本設計題目為 22 型客車車門墊板級進模設計，體現(xiàn)了級進模的設計要求、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，進一步加強了本人對級進模設計的基礎知識，為設計更復雜的級進模具做好了鋪墊和吸取了更深刻的經(jīng)驗。本設計運用沖裁工藝及模具設計的基礎知識，首先分析了板材的成分及性能要求，為選取沖裁方式做好了準備；然后選取了合理的排樣，提高了材料的合理利用率；接著分析計算凸凹模尺寸、及其它零部件的尺寸與制造方法，最后選取合適的的壓力機。對沖壓生產(chǎn)而言，單工位模具結構單一，生產(chǎn)效率低，而且鈑金零件不能過于復雜，否則就需要多副單工位模具才能實現(xiàn)。如果采用級進模進行沖壓生產(chǎn)，就可以改變這些缺點。級進模的特點是生產(chǎn)效率高，生產(chǎn)周期短，占用的操作人員少，非常適合大批量生產(chǎn)。本設計即為宇通客車車門墊板設計的級進模。關鍵詞：多工位級進模；排樣；設計；凸凹模； AbstractThe topic of design for the 22-passenger door Dianban progressive die design, reflects the progressive die design requirements, the contents and direction of a certain design significance. Parts of the mold through the design, I further strengthen the progressive die design of the basic knowledge for the design of more complex Progressive Die well pave the way and lessons more profound experience.The use of the design process and die design blanking the basis of knowledge, the first sheet of the composition and performance requirements, methods for selecting prepared for the punch and then select a reasonable layout to improve the rational utilization of the material; then Analysis of Tuao die size, and other parts of the size and manufacturing methods, the final selection of a suitable press.Stamping on the production, single-die structure for a single, low production efficiency, and sheet metal parts can not be too complicated or they need more of the single-die can be achieved. If using a progressive die stamping, you can change these shortcomings. Progressive Die is characterized by high productivity, short production cycle, occupied by the operators of small, very suitable for mass production. This design is the Yutong Bus doors Dianban design of progressive die.Key words: Progressive Die; layout, design, Tuao die;
