沖 壓 成 形 工 藝 及 模 具 設 計 摘 要本設計題目為上鉸鏈固定板復合模具設計，體現(xiàn)了典型復合模具設計的要求，內容與方向。通過工藝分析，工藝方案的確定，確定了模具設計的方向， 對毛坯尺寸的確定，計算沖裁力，來計算壓力中心，選擇壓力機和壓力機的噸位。本設計運用了沖裁工藝及模具設計的基礎知識。首先，分析了板材的性能要求，為選去模具的類型做了準備，同時，也為凸，凹模的材料有了依據(jù)。后分析沖裁件的特征，確定了模具設計參數(shù)，選擇其他零件及卸料裝置。也為凸，凹模尺寸的計算有了根據(jù)。還有零件的加工工藝。關鍵詞: 復合模 凸模 凹模 沖 壓 成 形 工 藝 及 模 具 設 計 ABSTRACTThis design topic designs for The piercing die design of the dunnage backup plate, body now typical model The piercing die design of request, contents and direction.Pass the craft analysis, the craft project really settles, making sure the direction of The piercing die design, really settling to the blank product size, computing to the blanking pressure, compute the pressure center, choose the tonnage of the pressure machine and the pressure machine.This design made use of to hurtle foundation knowledge of blanking craft and The piercing die design. First, Analyzed the function request of the plank material, did preparation for the type that chooses to the die, is also convex, in the meantime, the material of punch and cavitydie had a basis.Analyze to hurtle a characteristic of cut the piece behind, make sure the molding tool design parameter, choose other spare partses and unload to anticipate device.Is also convex, the calculation of the cave mold size had a basis.Still there is spare parts to process a craft.Keywords: The piercing die punch cavitydie
