[0018] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.

[0019] Embodiment 1

[0020] As Figures 1 to 3 shown, the pipe bender of this embodiment includes a machine base 1, a turntable 2, a servo motor 3, a pipe bending seat 4 and a pressing structure 5. The turntable 2 is rotatably arranged on the machine base 1. The pipe bending seat 3 is arranged on the turntable 2. The pipe bending seat 3 is columnar. A ring-shaped groove 41 is formed by inwardly concave on the side surface of the pipe bending seat 3 along its radial direction. A clamp 42 for clamping the pipe is arranged on the side surface of the pipe bending seat 4. The clamp 42 is located on one side of the groove 41. The servo motor 3 is installed on the machine base 1, and its output shaft is in transmission connection with the turntable 2 and drives the turntable 2 to rotate on the machine base 1. The pressing structure 5 is installed on the machine base 1 and is located on the right side of the pipe bending seat 4, and its pressing end faces the pipe. Among them, there are multiple grooves 41, corresponding to pipes of different sizes from top to bottom, and there are also multiple corresponding clamps 42, which are convenient for clamping the front ends of pipes of different sizes. During operation, the front end of the pipe is inserted into the clamp 42, and its inner side is embedded in the groove 41. The pressing structure 5 presses the outer side of the pipe to make the whole pipe in a balanced state. The servo motor 3 rotates, driving the turntable 2 to rotate. The turntable 2 drives the pipe bending seat 4 to rotate, so that the bend on the clamp 42 bends to the left. The pipe bender of this embodiment effectively improves the pipe bending efficiency; at the same time, using a servo motor to drive the pipe bending seat to rotate can achieve precise control and ensure the accuracy of the pipe bending angle. The pipe bender of the present utility model is small in volume, convenient to carry, and has strong practicability.

[0021] In this embodiment, the pipe bender further includes an auxiliary groove block 6. An auxiliary groove 61 is formed by outwardly concave on the inner side of the auxiliary groove block 6. The pipe is placed in the auxiliary groove 61. The pressing end of the pressing structure 5 presses on the outer side of the auxiliary groove block 6. The auxiliary groove 61 of the auxiliary groove block 6 and the groove 41 on the pipe bending seat 4 are used to clamp both sides of the pipe to prevent the pipe from swinging when being bent. The auxiliary groove block 6 and the clamp 42 are on the same horizontal plane, which is convenient for clamping the pipe.

[0022] In this embodiment, the pressing structure 5 includes a support rod 51, a sliding seat 52, a sliding rod 53, a pressing block 54 and a limiting screw 55. The support rod 51 is installed on the machine base 1 and is located on the right side of the elbow seat 4. The sliding seat 52 is installed on the support rod 51. The sliding rod 53 is horizontally slidably arranged on the sliding seat 52, and both ends thereof extend out of the sliding seat 52. The pressing block 54 is fixed to the left end of the sliding rod 53 and is aligned with the pipe. The limiting screw 55 is longitudinally threadedly embedded in the sliding seat 52, and its front end presses on the side surface of the sliding rod 53. Push the sliding rod 53 to move forward in the sliding seat until the pressing block 54 presses on the pipe, and rotate the limiting screw 55 to limit and fix the sliding rod 53, so that the pressing block 54 can press well on the pipe to prevent the pipe from swinging during bending. The pressing structure further includes two rollers 56. The two rollers 56 are installed at the left end of the pressing block 54. Since the pipe will move forward during bending, the roller form can reduce the friction force with the pipe surface. The number of the limiting screws 55 is two to enhance the limiting and fixing effect. The sliding seat 52 can be vertically limited and slid on the support rod 51 to adjust the height of the pressing block 54 to press pipes of different sizes.

[0023] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
