液壓剪(jian)(jian)(jian)板(ban)(ban)(ban)機(ji)(ji)主(zhu)要用(yong)于剪(jian)(jian)(jian)切鋼(gang)板(ban)(ban)(ban), 剪(jian)(jian)(jian)切厚(hou)度以被(bei)剪(jian)(jian)(jian)材料(liao)的(de)(de)抗拉強度為準, 如需(xu)剪(jian)(jian)(jian)其它(ta)強度的(de)(de)板(ban)(ban)(ban)料(liao)時(shi), 應依照被(bei)剪(jian)(jian)(jian)材料(liao)的(de)(de)抗拉強度相應的(de)(de)確定(ding)被(bei)剪(jian)(jian)(jian)板(ban)(ban)(ban)料(liao)的(de)(de)厚(hou)度。采(cai)用(yong)液壓主(zhu)傳動(dong),由CNC操(cao)(cao)縱(zong)(zong)的(de)(de)剪(jian)(jian)(jian)切設(she)備(bei),能(neng)準確地操(cao)(cao)縱(zong)(zong)后擋(dang)料(liao)以及(ji)剪(jian)(jian)(jian)切行程,剪(jian)(jian)(jian)切角、刀(dao)刃間隙及(ji)加工件數量,也可配(pei)置(zhi)由CNC操(cao)(cao)縱(zong)(zong)的(de)(de)夾鉗式前送(song)料(liao)裝(zhuang)置(zhi), 能(neng)方(fang)便地將板(ban)(ban)(ban)料(liao)送(song)至設(she)定(ding)尺寸, 減小工人勞動(dong)強度。機(ji)(ji)架為鋼(gang)板(ban)(ban)(ban)焊接(jie)結(jie)構,它(ta)包括左、右側板(ban)(ban)(ban)、工作臺、夾緊器座(zuo)及(ji)油箱；機(ji)(ji)架兩(liang)側各安裝(zhuang)一只液壓油缸(gang)及(ji)滑塊(kuai)導軌支座(zuo)，該(gai)導軌支座(zuo)是一個(ge)能(neng)夠操(cao)(cao)縱(zong)(zong)刀(dao)片間隙的(de)(de)推位機(ji)(ji)構。夾緊器上的(de)(de)液壓缸(gang)可緊緊地壓緊被剪(jian)切板(ban)材(cai)。

液壓剪板機傳動系統的(de)設計(ji)要求和運動分析：

該設(she)備的(de)設(she)計(ji)中有兩部分用(yong)到了液(ye)壓(ya)(ya)(ya)傳(chuan)動(dong)系(xi)統(tong)，一部分就是為帶動(dong)上刀架上線往復運動(dong)的(de)主油缸(gang)提供動(dong)力，為確保剪切(qie)精度(du)與穩定(ding)性，采用(yong)兩個(ge)單作(zuo)(zuo)用(yong)單活塞缸(gang)串聯完成(cheng)下壓(ya)(ya)(ya)動(dong)作(zuo)(zuo).此外，防(fang)止剪板(ban)過(guo)程中板(ban)材的(de)翹曲影(ying)(ying)響(xiang)(xiang)剪切(qie)質量而設(she)置的(de)液(ye)壓(ya)(ya)(ya)壓(ya)(ya)(ya)料機構，液(ye)壓(ya)(ya)(ya)元件的(de)選(xuan)擇要合理(li)來保證(zheng)整(zheng)個(ge)液(ye)壓(ya)(ya)(ya)傳(chuan)動(dong)系(xi)統(tong)工作(zuo)(zuo)時(shi)的(de)平穩。因為液(ye)壓(ya)(ya)(ya)油對污染特別(bie)敏(min)感，很(hen)微小的(de)污染都會影(ying)(ying)響(xiang)(xiang)到液(ye)壓(ya)(ya)(ya)系(xi)統(tong)的(de)精度(du)和(he)使用(yong)壽命，所以還要考慮到防(fang)塵防(fang)污和(he)減小噪聲等方面的(de)問題。

此(ci)外因為該設(she)備(bei)的(de)(de)(de)設(she)計中，采用的(de)(de)(de)斜刃(ren)剪(jian)(jian)(jian)(jian)切(qie)的(de)(de)(de)方(fang)式，上剪(jian)(jian)(jian)(jian)刀的(de)(de)(de)低(di)點離(li)下(xia)(xia)(xia)剪(jian)(jian)(jian)(jian)刀的(de)(de)(de)距(ju)離(li)非常短，所(suo)以在(zai)設(she)計液壓(ya)缸(gang)動(dong)作的(de)(de)(de)時候就(jiu)省略了快速(su)下(xia)(xia)(xia)降(jiang)，剪(jian)(jian)(jian)(jian)切(qie)過(guo)(guo)程(cheng)主油(you)缸(gang)只有(you)(you)工(gong)進(jin)這(zhe)一個(ge)(ge)動(dong)作，回(hui)程(cheng)的(de)(de)(de)時候也是(shi)(shi)只有(you)(you)一個(ge)(ge)動(dong)作，壓(ya)料(liao)油(you)缸(gang)的(de)(de)(de)下(xia)(xia)(xia)壓(ya)也是(shi)(shi)只有(you)(you)工(gong)進(jin)一個(ge)(ge)動(dong)作，回(hui)程(cheng)是(shi)(shi)在(zai)彈簧(huang)的(de)(de)(de)作用下(xia)(xia)(xia)完成的(de)(de)(de)。這(zhe)里(li)存在(zai)一個(ge)(ge)問題就(jiu)是(shi)(shi)，剪(jian)(jian)(jian)(jian)切(qie)過(guo)(guo)程(cheng)中，主油(you)缸(gang)和壓(ya)料(liao)油(you)缸(gang)的(de)(de)(de)動(dong)作并不是(shi)(shi)一致的(de)(de)(de)，為了保證剪(jian)(jian)(jian)(jian)切(qie)質量，壓(ya)料(liao)油(you)缸(gang)一定要在(zai)主油(you)缸(gang)動(dong)作之(zhi)前壓(ya)緊板材(cai)。
