沖壓(ya)模(mo)(mo)具(ju)是技術密集型產(chan)品，在國民經濟各領域、各行各業(ye)(ye)均得到了廣(guang)泛的應用(yong)。沖壓(ya)模(mo)(mo)具(ju)和塑料(liao)模(mo)(mo)具(ju)設(she)計與制造技術水平(ping)的高低(di)，是衡量一個國家制造業(ye)(ye)水平(ping)高低(di)的重要(yao)標志(zhi)，在很大程(cheng)度上(shang)決定著產(chan)品的質量、效(xiao)益和新產(chan)品開發的能力(li)。下(xia)面小編分享關于五(wu)金沖壓(ya)模(mo)(mo)具(ju)設(she)計技巧有哪些？怎么(me)提高使(shi)用(yong)壽命？的內容(rong)，歡迎閱讀！

五金沖壓模具設計技巧有哪些？

　　1、設計(ji)技巧:一(yi)般先(xian)(xian)裁邊,沖導正(zheng),打預斷,壓線,打凸點,撕(si)口(kou),,后沖孔落料,壓毛邊,成形(xing),分兩(liang)步折彎的,先(xian)(xian)成形(xing)一(yi)半,后成形(xing)另(ling)一(yi)半.

　　2、在五金模具(ju)沖(chong)(chong)(chong)(chong)(chong)壓件(jian)沖(chong)(chong)(chong)(chong)(chong)孔(kong)(kong)(kong)落料時(shi),一般先(xian)沖(chong)(chong)(chong)(chong)(chong)小(xiao)(xiao)(xiao)孔(kong)(kong)(kong),后(hou)沖(chong)(chong)(chong)(chong)(chong)大孔(kong)(kong)(kong):先(xian)沖(chong)(chong)(chong)(chong)(chong)落成形(xing)周邊的廢(fei)料,再落其它部位(wei)的余料:因為沖(chong)(chong)(chong)(chong)(chong)小(xiao)(xiao)(xiao)孔(kong)(kong)(kong)若放(fang)在后(hou)面(mian)(mian),那(nei)麼它在沖(chong)(chong)(chong)(chong)(chong)裁時(shi),沖(chong)(chong)(chong)(chong)(chong)子(zi)(zi)(zi)四周對(dui)應料帶上的部位(wei)可(ke)能(neng)有缺(que)口,這樣,沖(chong)(chong)(chong)(chong)(chong)子(zi)(zi)(zi)在沖(chong)(chong)(chong)(chong)(chong)壓過程中,將會引起受力不均,本來小(xiao)(xiao)(xiao)孔(kong)(kong)(kong)沖(chong)(chong)(chong)(chong)(chong)子(zi)(zi)(zi)強(qiang)度很弱,加之受力不均,極(ji)容(rong)易折斷,當然這僅是大多數(shu)情況(kuang),有時(shi)根(gen)據實際情況(kuang)需(xu)要(yao),小(xiao)(xiao)(xiao)孔(kong)(kong)(kong)沖(chong)(chong)(chong)(chong)(chong)隻能(neng)排(pai)在后(hou)面(mian)(mian),不過辦(ban)法還是有的,如果沖(chong)(chong)(chong)(chong)(chong)子(zi)(zi)(zi)厚度實在太小(xiao)(xiao)(xiao),可(ke)入行(xing)補(bu)強(qiang):A:採(cai)用脫板精密(mi)導向;B:沖(chong)(chong)(chong)(chong)(chong)子(zi)(zi)(zi)採(cai)用PG加工.

　　3、確定(ding)是(shi)否采用(yong)(yong)裁(cai)邊(bian)(bian):裁(cai)邊(bian)(bian)一(yi)般用(yong)(yong)在連續(xu)模和落料(liao)(liao)模上(shang),它的(de)作(zuo)用(yong)(yong)起粗定(ding)位(wei),在試模時(shi)便于送料(liao)(liao);有的(de)裁(cai)邊(bian)(bian)還兼有沖外形的(de)作(zuo)用(yong)(yong),如(ru)果模具(ju)先沖定(ding)位(wei)針孔,接著馬上(shang)用(yong)(yong)引(yin)導針導正,一(yi)般不用(yong)(yong)裁(cai)邊(bian)(bian)了(le);沒有引(yin)導針的(de),要先裁(cai)邊(bian)(bian),用(yong)(yong)來定(ding)距,一(yi)般用(yong)(yong)在落毛胚的(de)落料(liao)(liao)模中。

怎么提高五金沖壓模具的使用壽命？

　　1、材料(liao)的類型及(ji)厚度;

　　2、是(shi)否選(xuan)擇合理的下模間隙;

　　3、模具的結構形式;

　　4、材料沖壓時是否有良好的潤滑(hua);

　　5、模具是否經過特殊的表面處理;

　　6、如鍍(du)鈦、碳素(su)氮化鈦;

　　7、上下轉塔的對中性;

　　8、調(diao)整墊片的合理(li)使用;

　　9、是否適當采(cai)用斜(xie)刃口(kou)模具;

　　10、機(ji)床模座是否已經磨損;
