2477 彈簧座沖壓工藝及落料拉深復(fù)合模,彈簧,沖壓,工藝,落料拉深,復(fù)合 摘要：沖壓模具作為制造產(chǎn)品（或半產(chǎn)品）的一種工具，其作用是完成某種工藝。模具設(shè)計(jì)必須滿足工藝要求，最終滿足產(chǎn)品的形狀、尺寸和精度的要求。因此沖壓設(shè)計(jì)師必須掌握沖壓工藝，包括沖壓工藝的分類、各種工藝計(jì)算、工藝制訂等基礎(chǔ)知識(shí)，而后才可以選擇模具的類型，進(jìn)行模具設(shè)計(jì)，使模具的類型表面質(zhì)量、尺寸精度結(jié)構(gòu)及尺寸等滿足工藝及產(chǎn)品的要求。冷沖壓工藝大致分兩類：分離工序和成型工序。分離工序的目的是在沖壓過(guò)程中將沖壓件與板料按一定的輪廓線進(jìn)行分離：分離工序又可分為落料、沖孔和剪切等。成型工序的目的是使沖壓毛胚在不破壞其完整性的條件下產(chǎn)生塑性變形，并轉(zhuǎn)化成產(chǎn)品所需要的形狀：成形工序又分為彎曲、拉深、翻邊、翻孔、脹形、擴(kuò)孔等。對(duì)本零件的首道工序，本設(shè)計(jì)用正裝落料拉深復(fù)合模來(lái)完成。考慮到工件屬于旋轉(zhuǎn)體，是一般凸緣圓筒件，形狀簡(jiǎn)單、對(duì)稱。而且所用材料 08 鋼的塑性和韌性均高,無(wú)回火脆性傾向，拉深工藝性較好，圓角也較適合。故模具制造方便，兩道工序在一副模具中完成，生產(chǎn)效率高。關(guān)鍵詞：復(fù)合模 拉深工藝 塑性 韌性 模具制造Abstract：Hurtle a kind of tool of press the molding tool conduct and actions manufacturing product( or the half product), its function is to complete a certain craft. Therefore hurtling to press designer must control to hurtle to press the craft, the classification, various craft calculation, craft that includes to hurtle to press the craft establishes etc. the foundation knowledge, just can choose the type of the molding tool and then, carry on the molding tool design, make the type, structure and size etc. of the molding tool satisfy the request of the craft and product.Cold hurtle to press the craft to divide mostly two type: Separate the work preface and model the work preface. Purpose that separates the work preface is at hurtle to ran over the distance lieutenant general to hurtle to press the piece and planks to anticipate to press certain outline line to carry on the separation: Separating the work preface can is divided in to fall to anticipate again, blunt bore and shear to slice etc.. The purpose that models the work preface is to make hurtle to press the hair , the creation transforms under the condition of not break its integrity, and convert the shape that product need: Take shape the work preface and is divided into the flection and pull deep, turn over the side, turn over the bore, bulge form and expand the bore, etc.. Cold hurtle to press the molding tool is main craft equipments that hurtles to press to produce. Hurtle the surface quantity, size accuracy, rate of production and the economy performance etc.To the first work preface of the spare parts, this design use just pack to fall to anticipate to pull the deep compound mold to complete. In consideration of the work piece belongs to revolve the body, is a tube of general convex good luck piece, the shape is simple, symmetry. And 08 plastic and tenacities of the steels of material use are all high, did not return to the fire frailty sexual orientation, pull the deep craft better, a Cape is also iner keeping with. The past molding tool manufacturing is convenient, two work prefaces complete in a molding tool, producing the efficiency high.Keyword: The compound mold pulls、 the deep craft、 plastic 、plastictenacity molding tool manufacturing
