本機結(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動，通過絲桿絲母蝸桿傳動而獲得，兩下輥作旋轉(zhuǎn)運動，通過減速機的輸出齒輪與下輥齒合，為卷制板材提供扭矩。本機床結(jié)構(gòu)緊湊，操作維修方便。
The structure of this machine is a three roll symmetrical type. The upper roll moves vertically up and down at a symmetrical position in the center of the two lower rolls, which is obtained through the transmission of a screw and worm. The two lower rolls move in rotation, and the output gear of the reducer meshes with the lower roll to provide torque for the rolled sheet. This machine tool has a compact structure and is easy to operate and maintain.
