[0010] The beneficial effects of the present invention are as follows: 1. The present invention provides a driving mechanism. When the motor rotates, the operating states of the turntable are divided into two types: a: The turntable is stationary, the bending arc of the spring piece decreases, and its left end pushes the inner surface of the buckle to slide to the left along the slide groove. At the same time, the buckle rotates with the rotation of the connecting shaft, and the buckle is clamped into the inside of the clamp ring. The clamp ring rotates with the buckle. The drive belt drives the rotating shaft to rotate under the drive of the clamp ring, the pipe bending wheel rotates, and the pipeline moves into the equipment; b: The turntable rotates, the spring moves in the opposite direction, the buckle withdraws from the inside of the clamping ring, and the connecting shaft drives the fixed shaft to rotate.

When the equipment is in use, no matter what state the turntable is in, when the external pipe is difficult and has great resistance to bending, the farther the pipe bending wheel is from the fixed shaft, the greater the torque that the motor needs to output. High torque will increase the load inside the equipment and easily damage the equipment. In order to extend the service life of the equipment, the three-way pipe draws hydraulic oil into the hydraulic rod, and the hydraulic rod contracts. Under the joint action of the tension spring and the hydraulic rod, the telescopic rod contracts, and the rotating shaft drives the pipe bending wheel and the driving wheel to move downward along the main limit groove, and the sliding rod drives the tightening wheel to move downward along the secondary limit groove. The adjusting belt is stretched and deformed under the extrusion limit of the cable tie wheel to ensure that the lower surface of the adjusting belt is always in contact with the outer surface of the driving wheel to prevent it from falling off or slipping. Under the premise of ensuring the normal operation of the equipment, the pipe bending effect is ensured to remain unchanged, and it can adapt to the bending of pipes with different speeds, torques and bending curvatures, thereby solving the problem of low adaptability of traditional pipe bending machines.
