母排加工(gong)(gong)機剪(jian)切工(gong)(gong)位的(de)(de)設計。剪(jian)切技(ji)術：目前的(de)(de)剪(jian)切技(ji)術分為錯位式剪(jian)切和沖(chong)剪(jian)。　　

1、錯位(wei)剪切(qie)。

　　大多數銅(tong)排加(jia)工機剪(jian)(jian)切工站所采用(yong)的剪(jian)(jian)切方式(shi)，屬于錯(cuo)位剪(jian)(jian)切。這樣設(she)計模具制造簡單，剪(jian)(jian)裁方式(shi)簡明，便(bian)于使(shi)(shi)用(yong)者理解、操作和維護。但銅(tong)排切口(kou)往(wang)往(wang)不平(ping)整，切口(kou)光滑區域小(xiao)，切口(kou)傾斜，無法滿足使(shi)(shi)用(yong)要求。　　

2、沖剪(jian)。

　　經過調研和(he)相關資(zi)料分(fen)(fen)析，本設計(ji)采(cai)取沖(chong)(chong)剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)方式(shi)，。這(zhe)種加(jia)工(gong)(gong)(gong)(gong)方式(shi)較(jiao)剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)切(qie)(qie)來說更類似于(yu)沖(chong)(chong)孔，只不過沖(chong)(chong)孔的(de)(de)形(xing)(xing)狀是(shi)(shi)(shi)一條(tiao)很窄的(de)(de)矩形(xing)(xing)，是(shi)(shi)(shi)一種封閉剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)切(qie)(qie)。沖(chong)(chong)剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)時(shi)由于(yu)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)切(qie)(qie)削刃(ren)(ren)兩(liang)邊都(dou)接觸(chu)銅排，兩(liang)邊受力(li)對稱，因此加(jia)工(gong)(gong)(gong)(gong)出的(de)(de)銅排切(qie)(qie)口(kou)的(de)(de)整齊度和(he)質(zhi)量(liang)較(jiao)前者好(hao)。　　剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)切(qie)(qie)工(gong)(gong)(gong)(gong)站的(de)(de)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)設計(ji)。　　剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)切(qie)(qie)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)是(shi)(shi)(shi)銅排成(cheng)型的(de)(de)主要工(gong)(gong)(gong)(gong)作部分(fen)(fen)。整套剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)切(qie)(qie)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)分(fen)(fen)為(wei)上(shang)下(xia)兩(liang)部分(fen)(fen)，上(shang)部分(fen)(fen)為(wei)上(shang)切(qie)(qie)刀(dao)(dao)(dao)(dao)(dao)，下(xia)部分(fen)(fen)為(wei)固(gu)定(ding)(ding)刀(dao)(dao)(dao)(dao)(dao)，左右各一，所示，以(yi)上(shang)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)向下(xia)運動(dong)的(de)(de)方式(shi)進行加(jia)工(gong)(gong)(gong)(gong)。這(zhe)樣(yang)設計(ji)是(shi)(shi)(shi)考慮到銅排一般都(dou)放在(zai)較(jiao)低處的(de)(de)加(jia)工(gong)(gong)(gong)(gong)臺上(shang)，定(ding)(ding)位和(he)加(jia)工(gong)(gong)(gong)(gong)較(jiao)為(wei)方便；其次在(zai)加(jia)工(gong)(gong)(gong)(gong)的(de)(de)時(shi)候(hou)可以(yi)充分(fen)(fen)利用(yong)(yong)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)自身的(de)(de)重(zhong)量(liang)，將其轉(zhuan)化(hua)為(wei)有(you)用(yong)(yong)功(gong)，提(ti)高加(jia)工(gong)(gong)(gong)(gong)質(zhi)量(liang)。避免了固(gu)定(ding)(ding)刀(dao)(dao)(dao)(dao)(dao)向上(shang)運動(dong)重(zhong)力(li)成(cheng)為(wei)阻力(li)這(zhe)樣(yang)的(de)(de)弊端。　　在(zai)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)外(wai)形(xing)(xing)的(de)(de)設計(ji)中，一般有(you)平(ping)刃(ren)(ren)口(kou)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)和(he)斜(xie)刃(ren)(ren)口(kou)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)。用(yong)(yong)普通的(de)(de)平(ping)刃(ren)(ren)口(kou)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)沖(chong)(chong)剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)時(shi)，其整個(ge)刃(ren)(ren)口(kou)平(ping)面都(dou)同時(shi)接觸(chu)板(ban)料，故在(zai)沖(chong)(chong)裁(cai)大型或厚板(ban)工(gong)(gong)(gong)(gong)件時(shi)，沖(chong)(chong)裁(cai)力(li)往往很大。若將刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)刃(ren)(ren)口(kou)平(ping)面做成(cheng)與(yu)水平(ping)面傾斜(xie)一個(ge)角度，沖(chong)(chong)剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)時(shi)刃(ren)(ren)口(kou)就不是(shi)(shi)(shi)同時(shi)切(qie)(qie)入(ru)，而是(shi)(shi)(shi)逐步沖(chong)(chong)切(qie)(qie)材料，這(zhe)就等于(yu)減(jian)少了剪(jian)(jian)(jian)(jian)(jian)(jian)(jian)切(qie)(qie)斷(duan)面面積，因而可降低沖(chong)(chong)裁(cai)力(li)，同時(shi)可以(yi)減(jian)小對刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)的(de)(de)沖(chong)(chong)擊(ji)，因此本設計(ji)采(cai)用(yong)(yong)斜(xie)刃(ren)(ren)口(kou)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)。
