摘要
本課題生產(chǎn)的制件為空調(diào)墊片，材料為純鋁，制件厚度為1mm，采用沖孔落料級進(jìn)模具大批量生產(chǎn)。設(shè)計采用先沖孔，后落料形式。開始時的第一個定位采用始用擋料銷，由導(dǎo)料板和活動擋料銷粗定位后沖出Φ孔，然后由此孔做為導(dǎo)正孔，做精確定位，落料成品。采用這種定位沖孔落料方式，可以保證之間的精度。條料的排樣方式采用直對排，材料利用率可以達(dá)到85%。模架選用中間導(dǎo)柱導(dǎo)套形式，可以保證模具運行精度和模具壽命。這套模具加工簡單，安裝和調(diào)整也很方便，生產(chǎn)效率也很高，可以滿足設(shè)計要求。模具中的主要工作零件加工時才用熱處理，以保證其有適用的機(jī)械性能。
由于設(shè)計水平和實踐經(jīng)驗的局限性，設(shè)計當(dāng)中難免有錯誤和不足之處。在老師和同學(xué)幫助之下完成了這次設(shè)計課程，設(shè)計了一套空調(diào)墊片沖孔落料級進(jìn)模具，使自己積累了一定的設(shè)計經(jīng)驗。
關(guān)鍵詞：空調(diào)墊片 沖孔落料級進(jìn)模具 始用擋料銷 導(dǎo)料板 活動擋料銷

Abstract
What subject this produce make piece air conditioner spacer , material pure aluminium , make a thickness 1mm, adopt and wash the hole blanking grade and enter the mould to produce in enormous quantities. Design and adopt washing holes , and then blanking form first . The first localization at the beginning adopts the beginning to sell by blocking the material, go out of |μ hole after being led material board and activity and blocked the material and sold and made a reservation thickly, then therefore the hole is made in order to lead the straight hole, make and make a reservation accurately, the blanking finished product. Adopt the localization wash hole blanking way , can guarantee precision during. One kind of ways of arranging of a piece of material is adopted straight to arranging , the material utilization ratio can be up to 85%. The mould shelf leads the post to lead one set of forms while selecting for use, can guarantee the mould operation precision and life-span of mould . This set of moulds are processed simply, it is very convenient to install and adjust, production efficiency is very high, can meet the designing requirement . The groundwork part in the mould just uses the heat treatment while processing, so as to ensure that there is suitable mechanical performance in it.
Because of designing the limitation of competence and practical experience, unavoidably there are a mistake and weak point in the middle to design. Finish the course of designing under teacher and classmate help , design one air conditioner spacer wash hole blanking magnitude enter mould, make oneself accumulate certain design experience.
Keywords:Air conditioner spacer Wash the hole blanking grade and enter the mould The beginning is by blocking the material and selling Lead the material board The activity blocks the material to sell
