固定夾的沖壓成形工藝與模具設(shè)計 摘 要 本設(shè)計題目為復(fù)合模具設(shè)計 包括落料 沖孔和彎曲等工序的模具設(shè) 計 體現(xiàn)了典型復(fù)合模具設(shè)計的要求 內(nèi)容與方向 通過工藝分析以及工藝方 案的確定 確定了模具設(shè)計的方向 對毛坯尺寸的確定 沖裁力以及壓力中心 的計算 初步選擇壓力機和壓力機的噸位 并對其進行校核 本設(shè)計運用了沖裁工藝 彎曲工藝及模具設(shè)計的基礎(chǔ)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(shè)計參數(shù) 選擇其他零件及卸料裝 置 也為凸 凹模 凸凹模尺寸的計算有了根據(jù) 同時也為零件的加工工藝性 提供了依據(jù) 關(guān)鍵詞 復(fù)合模 凸模 凹模 凸凹模 彎曲模 Attaching clamp s drawing technology die design Abstract This 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 preliminary and check the parameter of the machine This design made use of to hurtle foundation knowledge of blanking craft and bending 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 punch die bending die
