一、折彎機的種類有哪些
折彎機分為手動折彎機、液壓折彎機和數控折彎機三種。手動折彎機又分為機械手動折彎機和電動手動折彎機。液壓折彎機按同步方式又可分為:機械同步折彎機、扭軸同步折彎機、機液同步折彎機和電液同步數控折彎機。
液(ye)壓折彎(wan)(wan)機(ji)(ji)按運(yun)(yun)動(dong)(dong)(dong)方式(shi)又可(ke)分為:上(shang)(shang)動(dong)(dong)(dong)式(shi)、下動(dong)(dong)(dong)式(shi)。下動(dong)(dong)(dong)式(shi)是工(gong)(gong)作(zuo)臺及(ji)工(gong)(gong)作(zuo)臺上(shang)(shang)的工(gong)(gong)件一起向上(shang)(shang)運(yun)(yun)動(dong)(dong)(dong),滑塊(kuai)不(bu)動(dong)(dong)(dong),目(mu)前國內市場(chang)上(shang)(shang)已(yi)經比較少見了(le)(le),多數(shu)是上(shang)(shang)動(dong)(dong)(dong)式(shi)的了(le)(le),上(shang)(shang)動(dong)(dong)(dong)式(shi)的是工(gong)(gong)作(zuo)臺及(ji)工(gong)(gong)作(zuo)臺上(shang)(shang)的工(gong)(gong)件不(bu)動(dong)(dong)(dong),滑塊(kuai)向下運(yun)(yun)動(dong)(dong)(dong)。按控(kong)制方式(shi)又可(ke)分為:普通液(ye)壓板料折彎(wan)(wan)機(ji)(ji)、經濟型數(shu)控(kong)折彎(wan)(wan)機(ji)(ji)和(he)電液(ye)同步數(shu)控(kong)折彎(wan)(wan)機(ji)(ji)。
二、折彎機的作用介紹
折彎機(ji)屬(shu)于鍛壓機(ji)械中的一種(zhong),主要作(zuo)用就是對板(ban)料特別是大型板(ban)料進行(xing)鈑金加工(gong)的首選機(ji)械,通過選配各種(zhong)不同的模具(ju),可以(yi)對板(ban)料進行(xing)彎邊、拉(la)伸(shen)、壓圓、沖孔等(deng)等(deng),廣泛適用于輕工(gong)、航空(kong)、船(chuan)舶、冶金、儀表、電(dian)器、不銹鋼(gang)制品、鋼(gang)結構建筑及裝潢(huang)行(xing)業(ye)。
折(zhe)彎機包(bao)括(kuo)支架、工作臺(tai)和夾緊板(ban),工作臺(tai)置(zhi)于支架上,工作臺(tai)由底(di)座和壓板(ban)構(gou)成(cheng)(cheng),底(di)座通(tong)過鉸鏈與夾緊板(ban)相連,底(di)座由座殼、線(xian)圈(quan)和蓋(gai)(gai)板(ban)組成(cheng)(cheng),線(xian)圈(quan)置(zhi)于座殼的凹(ao)陷內(nei),凹(ao)陷頂部覆有蓋(gai)(gai)板(ban)。
使用時由導線對線圈通電,通電后對壓板產生引力,從而實現對壓板和底座之間薄板的夾持。由于采用了電磁力夾持,使得壓板可以做成多種工件要求,而且可對有側壁的工件進行加工。折彎機可以通過更換折彎機模具,從而滿足各種(zhong)工件的需求。
