激(ji)光切(qie)割(ge)機是(shi)工(gong)業上不(bu)可(ke)缺少的設備之(zhi)壹(yi),往往我們(men)在使(shi)用(yong)激光切(qie)割(ge)機前(qian),都會(hui)將(jiang)制作好(hao)的圖紙導入(ru)到程(cheng)序,然(ran)後(hou)再利用(yong)排版(ban)軟件(jian)將(jiang)圖(tu)形(xing)排列(lie)在壹(yi)張板(ban)上(shang),這(zhe)樣激光切(qie)割(ge)機就(jiu)能夠(gou)對產(chan)品(pin)進(jin)行批(pi)量(liang)加(jia)工(gong)了.其(qi)中(zhong),排(pai)版(ban)過(guo)程(cheng)雖然(ran)很(hen)短(duan),但是(shi),在這(zhe)裏面卻(que)隱藏著很(hen)大(da)的學問(wen),排版(ban)稍(shao)有(you)不(bu)對(dui),就(jiu)會(hui)對(dui)整張板(ban)的切割效(xiao)果(guo)造成(cheng)很大(da)的影響.下(xia)面就(jiu)來(lai)給大(da)家(jia)講(jiang)解壹(yi)下(xia)激光切(qie)割(ge)機排(pai)版六(liu)大(da)註意(yi)事項:

1、拐(guai)角(jiao)熔化

        當減速(su)切(qie)割(ge)薄鋼(gang)板(ban)的拐(guai)角(jiao)時(shi),激光會(hui)因(yin)產生過熱(re)而熔化拐(guai)角(jiao).在拐(guai)角(jiao)處生成小(xiao)半(ban)徑,以(yi)保持(chi)激(ji)光的高速切(qie)割(ge),避免在切(qie)割拐(guai)角(jiao)時(shi)出現(xian)鋼(gang)板(ban)過(guo)熱(re)熔化現象(xiang),從而獲(huo)得良好(hao)的切割品(pin)質(zhi),並(bing)減少切割(ge)時(shi)間,提高生產力(li).

    2、零件(jian)間距(ju)

        壹(yi)般情況(kuang)下切(qie)割(ge)厚板(ban)和熱(re)板(ban),零(ling)件(jian)間間距(ju)要(yao)大(da),因為(wei)厚板(ban)熱(re)板(ban)熱(re)量(liang)影(ying)響較(jiao)大(da),在切(qie)割拐(guai)角(jiao)尖(jian)角(jiao)和小(xiao)圖(tu)形(xing)時候,容(rong)易燒邊,影響切(qie)割質(zhi)量(liang).

3、引線設置

        在切(qie)割較(jiao)厚(hou)板(ban)過(guo)程(cheng)中(zhong),為(wei)了使割(ge)縫銜(xian)接良好(hao),防止始(shi)端和終(zhong)點(dian),常(chang)常(chang)在切(qie)割開(kai)始(shi)和結(jie)束處各引壹段(duan)過(guo)渡線,分(fen)別稱作引線和尾(wei)線.引線和尾(wei)線對工(gong)件(jian)本(ben)身(shen)是(shi)沒有(you)用(yong)的,因此要(yao)安(an)排(pai)在工(gong)件(jian)範(fan)圍之(zhi)外(wai),同(tong)時註意(yi)不(bu)能(neng)將(jiang)引線設置在尖(jian)角(jiao)等(deng)不(bu)易散(san)熱(re)處.引線與(yu)割(ge)縫(feng)的連接(jie)盡量(liang)采(cai)用(yong)圓弧(hu)過(guo)渡(du),使機器運動(dong)平穩(wen)並(bing)避免轉角(jiao)停頓(dun)造成(cheng).

4、共(gong)邊切割

        將(jiang)兩(liang)種或以(yi)上(shang)的零件(jian)共(gong)邊成壹個(ge)組合(he),大(da)批(pi)量(liang)的規則圖形盡量(liang)共(gong)邊,共(gong)邊切割可(ke)以(yi)大(da)大(da)縮短(duan)切割(ge)時間,還(hai)能(neng)節省(sheng)原(yuan)材料(liao).

5、零(ling)件(jian)碰(peng)撞(zhuang)

        為(wei)使生產效(xiao)率(lv)較(jiao)大(da)化,許(xu)多(duo)激光切(qie)割(ge)設備都(dou)是(shi)24h連續運(yun)轉,並(bing)且使(shi)用(yong)無人(ren)操作的自(zi)動(dong)化上/卸(xie)料(liao)裝(zhuang)置,撞(zhuang)到切割(ge)完成(cheng)的傾翻(fan)零(ling)件(jian)而造(zao)成(cheng)切割頭損(sun)壞(huai)和生產中(zhong)斷(duan),帶(dai)來(lai)較(jiao)大(da)損失(shi).這(zhe)就(jiu)需要(yao)排序的時候註意(yi):

        ①選(xuan)擇(ze)合(he)適的切割路(lu)徑(jing),繞(rao)道(dao)已割好(hao)的零件(jian),減(jian)少碰撞(zhuang).

        ②選(xuan)擇(ze)較(jiao)佳(jia)的切割路(lu)線,減少切割(ge)時(shi)間.

        ③ 自(zi)動(dong)或手(shou)動(dong)將多(duo)個(ge)小(xiao)零(ling)件(jian)用(yong)微(wei)小(xiao)連接(jie)結(jie)合(he)起來(lai),切割(ge)完後,卸(xie)下(xia)的零件(jian),能(neng)輕(qing)易將微(wei)小(xiao)連接(jie)斷開(kai).

6、余(yu)料(liao)處理

        切割(ge)完零(ling)件(jian)後(hou),激(ji)光切(qie)割(ge)設備工(gong)作臺(tai)上(shang)的骨(gu)架狀余(yu)料(liao)需(xu)要盡快的撤(che)下,以(yi)方(fang)便後(hou)續的切割作業.對於(yu)不(bu)具有(you)自(zi)動(dong)卸(xie)料(liao)裝(zhuang)置的激光切(qie)割(ge)設備,可(ke)以(yi)將(jiang)骨(gu)架狀余(yu)料(liao)切(qie)割成小塊,以(yi)方(fang)便快速移(yi)走(zou).從而避(bi)免了操作者因搬動沈(chen)重(zhong)且邊緣鋒利的余(yu)料(liao)所(suo)造成的人(ren)身(shen)傷(shang)害(hai).
