·                       液壓式三輥對稱卷析機(jī)
性能與特點：
本機(jī)結(jié)構(gòu)型式為三輥對稱式，上輥在兩下輥中央對稱位置作垂直升降運(yùn)動，通過液壓缸內(nèi)的液壓油作用于活塞而獲得，為液壓傳動；兩下輥作旋轉(zhuǎn)運(yùn)動，通過減速機(jī)的輸出齒輪與下輥齒嚙合，為卷制板材提供扭矩。本機(jī)床結(jié)構(gòu)緊湊，操作維修方便。
Performance:
The construction of this machine is in the form of three roller symmetry.the top roller,inthe central vsymmetry position over the two bottom rollers.doesvertical motion up and down through screw,nut and worm transmission.Decelerator gears bottom rollers providing torsion moment for coiling sheet metal.THe construction of the machine is compact and the operation and maintenance is convenient.
