扭軸折彎機的主(zhu)要結構和功能是什(shen)么?
扭軸折彎機即扭(niu)軸同步折彎機。在扭(niu)力(li)軸同步結構(gou)的情況(kuang)下，根據功能和精度(du)，可以分為普通型、半數控型、數控型三(san)種。扭(niu)軸折彎機采用(yong)鋼(gang)焊接結構(gou)，具有足夠的強度(du)和剛度(du);液壓上傳動(dong)，將機床兩(liang)端的氣缸置于滑(hua)塊上，直接驅動(dong)滑(hua)動(dong)工作;滑(hua)塊同步機構(gou)采用(yong)扭(niu)軸強制同步;采用(yong)機械擋(dang)塊結構(gou)，穩定可靠(kao);滑(hua)塊行程機動(dong)快速調(diao)整，手動(dong)微調(diao)，計數器顯示;斜楔(xie)式撓(nao)度(du)補(bu)償機構(gou)，確保(bao)高彎曲(qu)精度(du)。
滑塊部(bu)分(fen):采用液(ye)壓傳動，滑塊部(bu)分(fen)由(you)(you)滑塊、氣(qi)缸(gang)和(he)機械(xie)(xie)(xie)塊精細(xi)調(diao)整(zheng)結構組成。左右油(you)缸(gang)固(gu)定在機架上(shang)，活塞(拉桿)通過液(ye)壓帶動滑塊上(shang)下，機械(xie)(xie)(xie)塊由(you)(you)數(shu)(shu)控(kong)(kong)系統控(kong)(kong)制(zhi)(zhi)(zhi)調(diao)節(jie)(jie)數(shu)(shu)值(zhi);工(gong)作臺部(bu)分(fen):由(you)(you)按(an)鈕盒控(kong)(kong)制(zhi)(zhi)(zhi)，使電機帶動擋板架來回移動，并由(you)(you)數(shu)(shu)控(kong)(kong)系統控(kong)(kong)制(zhi)(zhi)(zhi)移動距離，讀(du)數(shu)(shu)為0.01mm(行程開關限位前后位置);同(tong)步系統:該機由(you)(you)扭軸、擺(bai)臂、關節(jie)(jie)軸承等(deng)機械(xie)(xie)(xie)同(tong)步機構組成，結構簡單，性能穩定可靠，同(tong)步精度高(gao)。機械(xie)(xie)(xie)塊由(you)(you)電機調(diao)節(jie)(jie)，數(shu)(shu)值(zhi)由(you)(you)數(shu)(shu)控(kong)(kong)系統控(kong)(kong)制(zhi)(zhi)(zhi)。
擋料機(ji)構:擋料由電機(ji)驅(qu)動，通過鏈條(tiao)操作帶動兩絲杠同步運(yun)動，擋料尺寸由數(shu)控系統控制(zhi)。
扭軸折彎機是(shi)一種可(ke)以(yi)(yi)在(zai)(zai)薄板(ban)上(shang)(shang)(shang)進行折彎(wan)的(de)(de)(de)機(ji)(ji)器，結構(gou)主要包括支架、工(gong)(gong)作(zuo)臺和夾板(ban)，工(gong)(gong)作(zuo)臺放在(zai)(zai)支架上(shang)(shang)(shang)，工(gong)(gong)作(zuo)臺由(you)底(di)座(zuo)和夾鉗組(zu)成，底(di)座(zuo)通(tong)過合頁與夾板(ban)連接，底(di)座(zuo)由(you)殼體、線(xian)圈(quan)(quan)和板(ban)組(zu)成，線(xian)圈(quan)(quan)放置(zhi)在(zai)(zai)殼體內部(bu)凹陷(xian)，凹陷(xian)在(zai)(zai)蓋(gai)板(ban)頂部(bu)。使(shi)用(yong)時(shi)(shi)，導線(xian)對線(xian)圈(quan)(quan)通(tong)電，通(tong)電后，壓(ya)板(ban)產生(sheng)吸引力(li)，從而實現壓(ya)板(ban)與底(di)座(zuo)之間的(de)(de)(de)夾緊薄板(ban)。由(you)于采(cai)用(yong)電磁力(li)夾持，壓(ya)板(ban)可(ke)以(yi)(yi)做成各種要求的(de)(de)(de)工(gong)(gong)件，并(bing)且可(ke)以(yi)(yi)在(zai)(zai)工(gong)(gong)件的(de)(de)(de)側(ce)(ce)壁上(shang)(shang)(shang)加工(gong)(gong)，操作(zuo)也非常簡單(dan)。扭軸折彎(wan)機(ji)(ji)是(shi)依靠(kao)模(mo)具上(shang)(shang)(shang)的(de)(de)(de)滑(hua)(hua)(hua)塊來迫(po)使(shi)板(ban)材彎(wan)曲的(de)(de)(de)，但是(shi)滑(hua)(hua)(hua)塊很長，左右(you)兩(liang)(liang)端的(de)(de)(de)彎(wan)曲角度往(wang)往(wang)不同(tong)(tong)，滑(hua)(hua)(hua)塊上(shang)(shang)(shang)的(de)(de)(de)兩(liang)(liang)個氣(qi)缸(gang)如(ru)何實現同(tong)(tong)步是(shi)扭軸折彎(wan)機(ji)(ji)的(de)(de)(de)要點。扭軸扭軸折彎(wan)機(ji)(ji)采(cai)用(yong)扭軸同(tong)(tong)步桿(gan)結構(gou)，實現力(li)同(tong)(tong)步。油缸(gang)下移(yi)時(shi)(shi)，同(tong)(tong)時(shi)(shi)帶動(dong)滑(hua)(hua)(hua)塊下移(yi)。扭軸同(tong)(tong)步桿(gan)開始工(gong)(gong)作(zuo)，迫(po)使(shi)另一側(ce)(ce)氣(qi)缸(gang)下降(jiang)，從而達到(dao)氣(qi)缸(gang)同(tong)(tong)步的(de)(de)(de)目的(de)(de)(de)。
