U BENDING APPARATUS AND U-SHAPE BENDING METHOD THEREBY

摘要

The present invention relates to a device and a method for bending a bending member such as a pipe into a U shape, the bending portion being the center of the bending member. The present invention is a device for bending a bending member, comprising a central shaft and a rotational drive, the bending member is mounted in the interval between the center shaft and the rotational drive, the rotational drive is rotated about the center shaft And bending the bending member by hooking the central shaft. By using the bending machine, through the bending member mounting step, bending member center alignment step, bending member contact step and bending member bending step to provide a U-shaped bending method characterized in that the bending of the center of the bending member to make a U-shape do. According to the present invention, the bending member can be smoothly bent by the rotating means. According to the present invention, it is possible to bend the bending member efficiently by using two rotating means about the central shaft. According to the present invention can be controlled to bend the center of the bending member through the center alignment or close contact. According to the present invention provides an efficient and specific configuration of the means for implementing the effect.
