連接片級進模設(shè)計
摘 要
本設(shè)計題目為連接片級進模設(shè)計，體現(xiàn)了沖裁零件的設(shè)計要求、內(nèi)容及方向，有一定的設(shè)計意義。通過對該零件模具的設(shè)計，進一步加強了我對級進模設(shè)計的基礎(chǔ)知識，為以后設(shè)計更復(fù)雜的沖壓模做好了鋪墊和吸取了更深刻的經(jīng)驗。
本設(shè)計運用沖裁工藝及模具設(shè)計的基礎(chǔ)知識，首先分析工件的最小壁厚及其精度要求，確定模具的加工工藝方案。然后通過分析比較，確定了毛坯的排樣方式。最后確定模具的設(shè)計參數(shù)、設(shè)計要點及卸料裝置的選取。模具采用固定擋料銷粗定位，導(dǎo)正銷精定位，條料送進一次沖壓一次，工件和廢料都采取下出件方式，條料連續(xù)送進，連續(xù)沖壓。

Abstract
The topic of this design enters the mold design for continual slice and level, and this design manifests the rushing and cutting components’ design request, the content and the direction ,which has the certain design significance. Through designing this components mold ,I have further strengthened the basic knowledge to the level which the mold designed ,and also have some preparations for designing more complex dashing and pressing mould later , at the same time absorb more profound experience.
This design use rushing and cutting craft and the basic knowledge of mould designing , first analyze the minimum wallthickness of the work piece and its precision request ,meanwhile decide the plan of processing craft. Then determine platoon type way of the semifinished materials through analyzing and comparing . Finally decide the designing variable, the designing main point and selection of the dumping device of the mould.
