The limiting bottom grooves 32 are used to limit the bottom wall of the straight tube to be processed. Before installing the straight tube, the lifting cylinder 30 is turned on to move downward, and the straight tube is inserted into the arc-shaped loading groove 22, and then the lifting cylinder 30 is turned on to rise, and the arc-shaped loading groove 22 on the side wall of the guide roller 21 and the limiting bottom groove 32 on the top of the loading seat 31 are used to achieve stable clamping of the top and bottom of the tube body. During the clamping process, according to the diameter of different straight tubes, the lifting height of the lifting cylinder 30 is adaptively adjusted to maintain a constant holding force on the side walls of straight tubes of different diameters. After the straight tube is held, the motor 20 is turned on to achieve lateral transportation and bending processing of the straight tube;

[0024] The bidirectional bending assembly 4 includes several groups of electric push rods 40 symmetrically fixedly mounted on the inner top wall and the inner bottom wall of the shell 1.
