As further preferably, described sleeve pipe and axle and bearing adopt to sell and fix.
As further preferred, described castor is connected by the steel plate of pin with turning handle one end, two of described pin is arranged in the hole of described steel plate, when turning handle, pin and castor can freely rotate, during bend pipe, castor, in the one end in hole, can be moved on to the other end in hole, take out bend pipe by castor pin after bend pipe completes.
As further preferred, described fast pulley and castor are provided with the semi-circular recesses for placing pipe to be bent.
As further preferred, described in 3 groups, locking device is welded on support.
As further preferred, on the axle of described installation fast pulley position, side is provided with boss, opposite side is drilled with hole, fast pulley also there is corresponding hole, with pin, fast pulley is fixed on axle, make the diameter of axle greatly different, also can be set to stair-stepping, such fast pulley axially can not move and also can not rotate.
The beneficial effects of the utility model are: the direct manual bending power of workpiece changes into and passes to workpiece gained with the castor with arc surface by the utility model, can avoid the metaboly of workpiece bending part.Fast pulley and castor are arc structure, are beneficial to the profile ensureing bending pipe fitting.
The utility model can design support height and chassis plane area according to actual needs, and can obtain more firmly by support Design during design, area is larger.One is the complete machine stability increasing bending machine; Two is can be put on support in plane by the workpiece shaped, and reduces the labour intensity of operator's pickup back and forth, has saved a large amount of non-cutting time simultaneously.
The utility model can according to requirement of engineering, and the steel pipe bent flexibly or reinforcing bar are limited less, make operator only need to use less power just can complete bending work, reduce the labour intensity of operator, and its structure is simple, easy to process, bend pipe is steady.Described retention device can be used for preventing one end of the pipe when bend pipe from significantly moving to the opposite direction of bending direction; Castor need not be dismantled after bend pipe terminates, eliminate and reinstall, improve bend pipe efficiency, and decrease the possibility meeting accident and injure by a crashing object.
