在購買精密高速沖床時沖床噸位是要考慮到的關鍵原因之一。危害精密沖床噸位的關鍵要素包含零件周邊之長短、材(cai)(cai)料薄厚、材(cai)(cai)料強度(du)等特性。
平板面積及行程長度(du)則(ze)是因零件(jian)(jian)外(wai)形(xing)(xing)尺(chi)寸及深層來決策,對于每日(ri)產(chan)能(neng)(neng)關鍵(jian)系用(yong)于計算精密沖(chong)床之每分(fen)沖(chong)程數及所須(xu)沖(chong)床臺數,才可以(yi)合乎總體生產(chan)要(yao)求。以(yi)此(ci)將每個(ge)特(te)(te)性(xing)(xing)加(jia)(jia)總在一起(qi)考慮到(dao),包含零件(jian)(jian)加(jia)(jia)工(gong)(gong)特(te)(te)性(xing)(xing)、材(cai)料特(te)(te)性(xing)(xing)、應用(yong)工(gong)(gong)具特(te)(te)性(xing)(xing)等(deng)(deng),針對打胚(pei)、穿孔等(deng)(deng)工(gong)(gong)藝,需選(xuan)用(yong)短(duan)行程高速(su)率的(de)(de)(de)沖(chong)床,針對成形(xing)(xing)、引(yin)申等(deng)(deng)工(gong)(gong)藝,則(ze)需選(xuan)用(yong)長行程、且較慢(man)速(su)度(du)的(de)(de)(de)沖(chong)床,當用(yong)以(yi)壓模印(yin)、浮花印(yin)壓等(deng)(deng)工(gong)(gong)藝時,則(ze)須(xu)選(xuan)用(yong)在下死點(dian)時,具備高能(neng)(neng)量(liang)的(de)(de)(de)短(duan)行程沖(chong)床。
由此可見,沖床(chuang)噸位越(yue)大沖床(chuang)價錢就越(yue)高,在這里小編提示(shi)顧客,在選購沖床(chuang)時不必一味的關注沖床(chuang)價錢,僅有挑選合適自身沖壓模具商品的沖床(chuang)噸位才(cai)算是最 好(hao)的精密沖床(chuang)。
精密沖(chong)床(chuang)(chuang)彎(wan)折成(cheng)形生產加工一般(ban)應(ying)用(yong)A2級(ji)沖(chong)床(chuang)(chuang),如對制(zhi)品精度(du)尤(you)其是回彈(dan)力量規定(ding)嚴(yan)格時,板(ban)厚容許誤差(cha)不大的錫(xi)青銅(tong)和其他薄板(ban)件的彎(wan)折,僅有應(ying)用(yong)A1級(ji)沖(chong)床(chuang)(chuang)才可(ke)以(yi)做到所規定(ding)的精度(du)。因此 ,制(zhi)品材(cai)料(liao)薄厚的不同比沖(chong)床(chuang)(chuang)規格型號還(huan)關鍵。如2級(ji)精度(du)材(cai)料(liao)在開展彎(wan)折成(cheng)形時精度(du)上(shang)沒有什么(me)難題得(de)話(hua),應(ying)用(yong)B2級(ji)沖(chong)床(chuang)(chuang)也可(ke)以(yi)獲(huo)得(de)不錯的結(jie)果。但那(nei)樣的板(ban)材(cai)有時候會滲入(ru)厚而(er)硬的材(cai)料(liao),使模貝(bei)造(zao)成(cheng)負載狀況,如精密沖(chong)床(chuang)(chuang)剛(gang)度(du)好,很有可(ke)能不造(zao)成(cheng)形變,但導致模貝(bei)毀(hui)壞或形變。
