1動 片 零 件 沖 壓 成 形 工 藝 及 模 具 設(shè) 計 摘要:本設(shè)計為動片落料拉伸級進模設(shè)計。通過對該零件模具的設(shè)計，進一步加強了設(shè)計者沖壓模設(shè)計的基礎(chǔ)知識，為設(shè)計更復(fù)雜的沖壓模具做好了鋪墊和吸取了更深刻的經(jīng)驗。本設(shè)計運用沖壓成形工藝及模具設(shè)計的基礎(chǔ)知識，首先分析了沖壓件的外形及用處性能要求，為選取模具的類型做好了準備；然后計算了沖壓力，便于選取壓力機；最后計算了制件的壓力中心，確定模具的設(shè)計參數(shù)、設(shè)計要點及推出裝置的選取。設(shè)計級進模，首先要設(shè)計條件排樣圖。動片零件的形狀簡單。由于零件外形尺寸為自由尺寸對精度要求不高，為了提高材料的利用率減少沖裁力，雖然這時會使零件外形尺寸公差等級降低但是經(jīng)過籌兼顧，全面考慮。這里我們采用少廢料排樣。凹模采用整體式凹模，各沖裁的凹?？拙捎镁€切割機床加工，安排凹模在模架上的位置時要依據(jù)計算壓力中心與模柄中心重合。關(guān)鍵詞:級進模 、少廢料排樣 、下出料方式、彈性擋料銷 、壓料板 2Moving piece parts of The Stamping Die Design Abstract: The move is designed to stretch film blanking Progressive Die Design. Parts of the mold through the design, designers have further strengthened the basis for stamping die design knowledge, for the design of more complex stamping die to do a good job of paving the way and draw a more profound experience. The design and use of stamping die design of the basic knowledge ,first of stamping parts of the appearance and usefulness of performance requirements. To select the type of mold prepared for the Die Design design,Chong then calculate the pressure for selecting press,the final calculation of the pressure on the central parts, the design parameters established mold, design elements and the introduction of the selected devices。Progressive Die Design, first of all conditions to design the layout plan. Moving parts of the shape of a simple film. Dimension as a result of the free parts of the accuracy of modest size, in order to enhance the utilization of materials to reduce the blanking force, although this dimension tolerance parts will reduce the level of financing, however, after both, taken as a whole. Here we used nesting less waste.Die using integrated die, blanking the die-adopted WEDM processing, for die-shelf in the position should be calculated based on pressure center and center-stalk coincidence.Keywords: Progressive die,little nesting materials, the materials under way pin block material, discharge board
