    • Disclosed is a roller hemming device, which is capable of excellent hemming even when a subject to be hemmed is located in a relatively narrow place, and reducing maintenance frequency. Specifically disclosed is a roller hemming device, which includes a preliminary bending roller for performing preliminary bending of a work, a final bending roller for performing final bending of the work, and an arm for setting attitudes of the preliminary bending roller and the final bending roller at desired positions and angles. The preliminary bending roller has an axis inclined with respect to a horizontal direction and is arranged at such a position not to come in contact with the work during the final bending. The final bending roller is formed in a circular truncated cone, has an axis which is inclined with respect to the horizontal direction so that, during the final bending, a large diameter surface thereof faces toward the work and a processing surface thereof is horizontally positioned, and is arranged at such a position not to come in contact with the work during the preliminary bending. The preliminary bending roller and the final bending roller are arranged along a top-bottom direction, each having a processing point located in a vicinity of an axis of the arm.
    • 公开了一种辊式折边装置,即使在被卷绕的被摄体位于相对狭窄的位置,也能够优异的折边,并且降低维护频率。 具体公开了一种辊式折边装置,其包括用于进行工件的预弯曲的预备弯曲辊,用于进行工件的最终弯曲的最终弯曲辊以及用于设定预弯曲辊和最终弯曲辊的姿态的臂 在期望的位置和角度。 预弯曲辊具有相对于水平方向倾斜的轴线,并且布置在在最终弯曲期间不与工件接触的位置。 最终弯曲辊形成为圆形截锥体,具有相对于水平方向倾斜的轴线,使得在最终弯曲期间,其大直径表面面向工件并且其处理表面水平定位, 并且布置在在预备弯曲期间不与工件接触的位置。 初步弯曲辊和最终弯曲辊沿着上下方向布置,每个具有位于臂的轴线附近的加工点。
