導(dǎo) 向 板 沖 壓 工 藝 及 模 具 設(shè) 計(jì) 摘 要本設(shè)計(jì)題目為導(dǎo)向板沖裁模與彎曲模，體現(xiàn)了典型冷沖模的設(shè)計(jì)要求、內(nèi)容及方向，有一定的設(shè)計(jì)意義。通過對該模具的設(shè)計(jì)，加強(qiáng)了設(shè)計(jì)者對冷沖模設(shè)計(jì)基礎(chǔ)知識(shí)的理解和運(yùn)用，為設(shè)計(jì)更復(fù)雜的沖裁模具做好了鋪墊。本設(shè)計(jì)運(yùn)用沖裁與彎曲工藝及模具設(shè)計(jì)的基礎(chǔ)知識(shí)，首先分析了板材的性能要求，為選取模具的類型做好了準(zhǔn)備；然后計(jì)算了獲得零件的沖裁力和彎曲力，便于選取壓力機(jī)噸位及確定壓力機(jī)型號(hào)；最后分析了零件的特征，便于確定模具的設(shè)計(jì)參數(shù)、設(shè)計(jì)要點(diǎn)及卸件裝置。本設(shè)計(jì)采用了沖孔落料模和彎曲模。成形原理可劃分為兩個(gè)階段：首先沖孔落料，而后彎曲成形。關(guān)鍵詞： 沖孔落料模和彎曲模 沖孔凸模、凹模 彎曲凸模、凹模 壓力機(jī)噸位 Oriented plate stamping parts and die design process AbstractThis design topic for the guidance board blanking and the bending die, has manifested the design request, the content and the direction which the model dies coldly, has certain design significance.Through to this mold design, strengthened the designer to die coldly the design elementary knowledge understanding and the utilization, for designed the more complex blanking mold to complete the upholstery.This design the elementary knowledge which designs using the blanking and the curving craft and the mold, first has analyzed the plate performance requirement, for selected the mold the type to prepare for; Then calculated has obtained the components the blanking force and the bending force, was advantageous for the selection press tonnage and the definite press model; Finally has analyzed the components characteristic, is advantageous for determines the mold the design variable, the design main point and the shedder. This design has used the punch holes cut-off curving continual mold.The formed principle may divide is two stages: First the punch holes raised mold and the concave, after but the completes the cut-off curving forming. Key word: Punch holes cut-off curving continual mold Punch holes raised mold, concave mold Curving raised mold, concave mold Press tonnage
