　　機(ji)(ji)(ji)械剪板機(ji)(ji)(ji)的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)系統由電動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)、小帶(dai)輪(lun)(lun)、大帶(dai)輪(lun)(lun)、軸承、減(jian)(jian)(jian)速(su)箱(xiang)(xiang)小齒(chi)(chi)輪(lun)(lun)、減(jian)(jian)(jian)速(su)箱(xiang)(xiang)大齒(chi)(chi)輪(lun)(lun)、十(shi)字聯(lian)軸器(qi)、傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)小齒(chi)(chi)輪(lun)(lun)、傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)大齒(chi)(chi)輪(lun)(lun)、傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)軸、偏心(xin)輪(lun)(lun)、主(zhu)軸、上刀(dao)(dao)架(jia)等(deng)組成。電動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)裝(zhuang)在(zai)(zai)減(jian)(jian)(jian)速(su)箱(xiang)(xiang)上，經過三角皮(pi)帶(dai)帶(dai)動(dong)(dong)(dong)(dong)(dong)(dong)大飛輪(lun)(lun)，當(dang)(dang)離(li)合(he)器(qi)通(tong)氣時，驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)減(jian)(jian)(jian)速(su)箱(xiang)(xiang)從動(dong)(dong)(dong)(dong)(dong)(dong)軸旋(xuan)轉(zhuan)，減(jian)(jian)(jian)速(su)箱(xiang)(xiang)輸出軸經過十(shi)字聯(lian)軸器(qi)帶(dai)動(dong)(dong)(dong)(dong)(dong)(dong)剪板機(ji)(ji)(ji)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)軸旋(xuan)轉(zhuan)，傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)大小齒(chi)(chi)輪(lun)(lun)嚙(nie)合(he)，帶(dai)動(dong)(dong)(dong)(dong)(dong)(dong)主(zhu)軸旋(xuan)轉(zhuan)，經過連(lian)桿機(ji)(ji)(ji)構帶(dai)動(dong)(dong)(dong)(dong)(dong)(dong)刀(dao)(dao)架(jia)上下運動(dong)(dong)(dong)(dong)(dong)(dong)，實施剪切(qie)。當(dang)(dang)電磁分配閥斷電，離(li)合(he)器(qi)制(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)，電機(ji)(ji)(ji)作(zuo)空工作(zuo)，刀(dao)(dao)架(jia)停在(zai)(zai)待工作(zuo)位置。

　　本(ben)機采用(yong)的(de)是(shi)起浮鑲塊式沖突(tu)離合(he)(he)(he)器(qi)(qi)(qi)(qi)-制動器(qi)(qi)(qi)(qi)，首要部分(fen)包(bao)括：大飛(fei)輪、離合(he)(he)(he)器(qi)(qi)(qi)(qi)缸(gang)體、離合(he)(he)(he)器(qi)(qi)(qi)(qi)活(huo)塞、離合(he)(he)(he)器(qi)(qi)(qi)(qi)自(zi)動盤(pan)、離合(he)(he)(he)器(qi)(qi)(qi)(qi)從(cong)(cong)動盤(pan)、沖突(tu)鑲塊、制動器(qi)(qi)(qi)(qi)推(tui)桿、從(cong)(cong)動軸、制動器(qi)(qi)(qi)(qi)法蘭、制動器(qi)(qi)(qi)(qi)缸(gang)體、制動器(qi)(qi)(qi)(qi)活(huo)塞、制動器(qi)(qi)(qi)(qi)繃簧等組成(cheng)。

　　動(dong)作(zuo)(zuo)過程如下：電(dian)(dian)磁空氣(qi)分配閥通電(dian)(dian)敞開后，緊(jin)縮空氣(qi)進入離(li)(li)合器(qi)(qi)(qi)缸體(ti)后向右推(tui)動(dong)離(li)(li)合器(qi)(qi)(qi)活(huo)塞，一起推(tui)動(dong)從(cong)動(dong)軸(zhou)內制動(dong)器(qi)(qi)(qi)推(tui)桿向右移(yi)動(dong)，這時離(li)(li)合器(qi)(qi)(qi)活(huo)塞緊(jin)縮繃(beng)簧，使制動(dong)器(qi)(qi)(qi)托(tuo)開，一起離(li)(li)合器(qi)(qi)(qi)自動(dong)盤將沖突鑲塊(kuai)夾緊(jin)，依靠(kao)沖突力，由大(da)飛輪帶動(dong)從(cong)動(dong)軸(zhou)轉動(dong)工(gong)作(zuo)(zuo)。反(fan)之，電(dian)(dian)磁空氣(qi)分配閥斷電(dian)(dian)，離(li)(li)合器(qi)(qi)(qi)缸體(ti)先排(pai)氣(qi)，制動(dong)器(qi)(qi)(qi)活(huo)塞在繃(beng)簧效果下向左移(yi)動(dong)，夾緊(jin)沖突鑲塊(kuai)完成制動(dong)，一起離(li)(li)合器(qi)(qi)(qi)活(huo)塞在制動(dong)器(qi)(qi)(qi)推(tui)桿效果下向左移(yi)動(dong)，使離(li)(li)合器(qi)(qi)(qi)自動(dong)盤分隔，大(da)飛輪空工(gong)作(zuo)(zuo)。

　　機床出現(xian)的溜車故障(zhang)原因分析與處理

　　在實踐(jian)中，咱(zan)們經過多年的修補溜車現象的經歷，對發作原因(yin)首要總結為以下幾個(ge)方(fang)面，并相應(ying)的摸索出了處理辦法：

　　1)制(zhi)動(dong)器(qi)發作的(de)制(zhi)動(dong)力(li)太小(xiao)，首要有3個方面：制(zhi)動(dong)器(qi)繃簧(huang)壓力(li)調整太小(xiao);制(zhi)動(dong)器(qi)繃簧(huang)長期使(shi)用彈性(xing)下降;沖突鑲塊磨損(sun)較重，導致制(zhi)動(dong)力(li)矩下降。

　　處(chu)理辦法：調(diao)整制(zhi)(zhi)動器(qi)緊縮繃(beng)簧(huang)和制(zhi)(zhi)動器(qi)推桿的調(diao)整螺栓;替換制(zhi)(zhi)動器(qi)緊縮繃(beng)簧(huang);替換沖突鑲塊。

　　2)離(li)(li)(li)合(he)(he)器從(cong)動(dong)盤(pan)(pan)與(yu)中(zhong)間(jian)套滾(gun)鍵，導致傳動(dong)不(bu)(bu)能脫離(li)(li)(li)。離(li)(li)(li)合(he)(he)器從(cong)動(dong)盤(pan)(pan)與(yu)離(li)(li)(li)合(he)(he)器自(zi)動(dong)盤(pan)(pan)在沒有(you)通緊縮空氣(qi)時是分(fen)隔的(de)，各自(zi)工作(zuo)互不(bu)(bu)影(ying)響(xiang);只有(you)當通氣(qi)后，靠(kao)沖突鑲塊(kuai)沖突力將離(li)(li)(li)合(he)(he)器自(zi)動(dong)盤(pan)(pan)、離(li)(li)(li)合(he)(he)器從(cong)動(dong)盤(pan)(pan)連接(jie)起來一起工作(zuo)。軸承內圈靠(kao)軸套調整間(jian)隙，外(wai)圈靠(kao)壓蓋(gai)壓緊調整間(jian)隙。

　　處(chu)理辦法：修離合器從(cong)動盤內孔(加(jia)大、找(zhao)正(zheng)、找(zhao)形位精度)，并重新插鍵(jian)槽，再配作(zuo)中間套和鍵(jian)。

　　3)離合(he)器活塞密(mi)封(feng)圈老化損壞(huai)或離合(he)器活塞與(yu)離合(he)器缸體研損，導致頂(ding)力(li)缺乏。

　　處理辦法：將離合器(qi)活塞拆下(xia)來，鍵是固定在(zai)活塞外圓上(shang)與活塞一起在(zai)氣缸(gang)內孔上(shang)滑動，查看活塞外圓，看是否有(you)研(yan)磨亮點，如有(you)需用(yong)砂紙打磨后使用(yong)。查看密(mi)封圈無缺情況，如有(you)損壞替換密(mi)封圈。

　　4)制動器活塞與制動器缸體發作研磨，導致(zhi)制動器推桿(gan)不能(neng)到位，不能(neng)壓(ya)實沖突(tu)鑲塊，使制動力減(jian)小(xiao)。

　　處(chu)理(li)辦法：查(cha)看(kan)配合外表(biao)，如有研(yan)磨，會(hui)有很多的鐵屑、氧化鐵皮之(zhi)類的臟東西，用鋸條、鋼絲刷等整理(li)掉(diao)后(hou)，用煤油(you)清洗一遍，露出潤滑的外表(biao)，高點也用砂紙打磨好。
