[0026] A heating mechanism is provided between the clamping mechanism and the bending mechanism.

[0027] Furthermore, the heating mechanism includes a second movable frame 400 and a first heating coil 410. A second slide rail 120 is provided in the middle of the first frame 100.

A second cylinder 420 is provided at the front end of the first frame 100. The second cylinder 420 is connected to the front end of the second movable frame 400. The first heating coil 410 is disposed at the upper end of the second movable frame 400.

[0028] Furthermore, the first clamping assembly includes a first clamp 320, a second clamp 330, and a third cylinder 340.

[0029] Furthermore, a first limiting block 111 is provided at the left end of the first slide rail 110, a second limiting block 112 is provided at the right end of the first slide rail 110, a first sensor 130 is provided at the rear end of the first frame 100, the first sensor 130 corresponds to the middle part of the first slide rail 110, and the first sensor 130 is matched with the first movable frame 300.

[0031] Working principle: First, the third cylinder 340 moves the second clamp 330 away from the first clamp 320, placing the steel pipe 430 between the first clamp 320 and the second clamp 330. The third cylinder 340 then moves the second clamp 330 closer to the first clamp 320, causing the first clamp 320 and the second clamp 330 to clamp the steel pipe 430. The second cylinder 420 pushes the second moving frame 400 backward until it reaches the fourth limiting block 122. The first cylinder 310 pushes the first moving frame 300 to the left. When the first sensor 130 detects the first moving frame 300, the first heating coil 410 begins to heat the steel pipe 430. After heating, the first moving frame 300 then moves the steel pipe 430 to the right and moves the second moving frame 400 forward, allowing the steel pipe 430 to move into the interior of the first bending frame 200. The first hydraulic cylinder 240 pushes the first push rod to the right, and the first push rod pushes the first connecting rod 231 and the second connecting rod 232 through the first push plate 230. The first connecting rod 231 pushes the first lifting member 220 to rise, so that the first lifting member 220 holds the steel pipe 430. The third cylinder 340 drives the second clamp 330 away from the first clamp 320, that is, releases the steel pipe 430. The first hydraulic cylinder 240 continues to push the first lifting member 220 to rise, so that the first lifting member 220 pushes the steel pipe 430 toward the first forming member 210, so that the steel pipe 430 is hot bent and formed.
