[0027] Further, the driving assembly 3 comprises a motor 301, a gear set 302 and a rotating gear 303, the gear set 302 is located inside the moving plate 202, the motor 301 and the rotating gear 303 are driven through the gear set 302, the rotating gear 303 is engaged with the inner wall of the sliding rail 201, so that the clamping assembly 2 is mainly driven by the driving assembly 3 alone, and the forward and backward movement on the sliding rail 201 is realized according to the motor 301, the gear set 302 and the rotating gear 303.

[0028] Further, the lifting seat 4 inside comprises an electric telescopic rod 402 and a PLC controller, the PLC controller is connected with the equipment body 1, the motor 301 and the electric telescopic rod 402 respectively, so that the PLC controller can control the motor 301 and the electric telescopic rod 402 respectively after being set by the worker, the motor 301 comprises a contactor and a driving workpiece, the driving workpiece is used for calculating the moving distance of the moving plate 202, the driving workpiece can be a Hall encoder or an optical encoder, and the driving assembly 3 can be conveniently moved forward and backward on the sliding rail 201 based on the forward rotation and the reverse rotation, in this process, the PLC controller always makes the moving plate 202 located in the middle of the pipe body in the initial state according to the distance record; the PLC controller is also connected to the equipment body 1, when the pipe bending assembly 102 acts, the electric telescopic rod 402 starts to act, the pipe body is loosened and lowered, and then rises to clamp after moving to the middle of the pipe body.

[0029] Further, the clamping pad 7 is made of rubber pad, and the clamping pad 7 is arranged in an upper and lower combination, so that the rubber pad can protect the pipe body during clamping.

[0030] Specifically, since the pipe body to be processed by the ship body part is usually long, and the auxiliary pushing structure 101 mainly produces the axial pushing effect, the middle part of the pipe body will bend downward without support, therefore, the clamping assembly 2 based on the sliding rail 201 is designed on the surface of the equipment body 1, in the conventional state, the upper fixed arc plate 5 is directly fixed and supported by the moving plate 202 through the support 502, the lifting arc plate 6 is continuously lifted upward by the lifting seat 4 at the bottom, so that the fixed arc plate 5 and the lifting arc plate 6 clamp and fix the middle part of the pipe body upward and downward, and when the clamping force is applied, the clamping pad 7 made of rubber can protect the surface of the pipe body, so that the clamping assembly 2 can form the effect of supporting the middle part, and at the same time, the pipe body is sent to one side of the pipe bending assembly 102 for bending operation;

[0031] When the pipe bending assembly 102 completes the action, the lifting seat 4 is retracted downward to loosen the pipe body and retreat to the original position, and then the lifting arc plate 6 is clamped from the lower part again by the electric telescopic rod 402, and the effect of supporting and auxiliary pushing between the auxiliary pushing structure 101 and the pipe bending assembly 102 is continued, until the whole structure process of the pipe body is completed, not only the axial positioning of the pipe body is formed, but also the center of the pipe body can be kept straight in the pipe bending process.

[0036] The support column 502 is installed in pairs in front and back, and there are at least two support columns 502 on one side wing plate 501.

[0037] Specifically, when the clamping pad 7 uses hard metal material, the clamping pad 7 can be further used as the main clamping structure according to the actual pipe shape, and the clamping pad 7 is fixed by the fixing bolt 702 and the screw 701. When the inner diameter needs to be adjusted, the fixing bolt 702 can be screwed inward, and the smaller diameter clamping pad 7 can be installed by cooperating with the screw 701, so that the smaller diameter pipeline can be supported and assisted by the clamping assembly 2.

[0038] In addition, the clamping pad 7 is not only arc-shaped structure with the fixed arc plate 5 and the lifting arc plate 6, but also can form an upper and lower combined rectangular cross-section structure or other shape cross-section, so that different shaped pipelines can continue to be used by replacing different clamping pads 7, further increasing the versatility of the clamping assembly 2.
