[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Reference Figures 1-4 A pipe bending machine includes a frame 1, a support 2 is fixed on the top of the frame 1, a T-shaped slide 3 is slidably connected to the inside of the support 2, a slide groove 31 is opened inside the T-shaped slide 3, a slider 4 is slidably connected to the inside of the slide groove 31, a clamping block 5 is fixed to the top surface of the slider 4, a pipe body 6 is clamped in the middle of the clamping block 5, a fixing plate 7 is fixed to the side wall of the frame 1, a pillar 8 is embedded and fixed in the middle of the fixing plate 7, an abutting pressure wheel 81 is fixed to the top of the pillar 8, a rotating column 9 is rotatably sleeved on the outside of the pillar 8, and a mounting seat 10 is fixedly sleeved on the outside of the rotating column 9;

[0051] A pipe bending machine also includes a sliding part, a clamping part, a driving part and a bending part. The sliding part is used to drive the T-shaped slide 3 to slide horizontally, the clamping part is used to clamp the pipe body 6, the driving part is used to drive the rotating column 9 to rotate, and the bending part is used to bend the pipe body 6.

[0052] Furthermore, the sliding member includes a first motor 32 and a screw 33. The first motor 32 is fixed to the side wall of the support 2, and the screw 33 is fixed to the output end of the first motor 32. The screw 33 rotates within the support 2. The interior of the T-shaped slide 3 is provided with external threads that mate with the threads of the screw 33. When the screw 33 rotates, the interaction between the threads causes the T-shaped slide 3 to move linearly along the direction of the screw 33.

[0053] Furthermore, the clamping member includes a double-headed screw 41 and a rocker 42 . The double-headed screw 41 is rotatably connected in the slide groove 31 , and the rocker 42 is fixed at the end of the double-headed screw 41 .

[0054] Furthermore, the clamping member includes a telescopic rod 51 fixed to the inner wall of the clamping block 5. The telescopic rod 51 has a certain telescopic ability and can extend or shorten when subjected to external force. A spring 52 is sleeved on the telescopic rod 51, and a clamping ring 53 is fixed to the end side of the telescopic rod 51. The two ends of the spring 52 are respectively fixedly connected to the side walls of the clamping ring 53 and the inner wall of the clamping block 5. The spring 52 provides a clamping force. When the clamping ring 53 contacts the pipe body 6, the spring 52 is compressed, thereby generating an outward clamping force to firmly clamp the pipe. When the pipe needs to be released, the spring 52 returns to its original state, causing the clamping ring 53 to loosen. There are two sliders 4 and two clamping blocks 5, and the two sliders 4 and two clamping blocks 5 are in the same direction as the slider 4.

[0055] Furthermore, the driving member includes a second motor 91, a transmission shaft 92, a driving gear 93 and a driven gear 94. The second motor 91 is fixed to the bottom surface of the frame 1, the transmission shaft 92 is fixed to the output end of the second motor 91, the driving gear 93 is sleeved on the transmission shaft 92, and the driven gear 94 is fixed on the rotating column 9. The driving gear 93 and the driven gear 94 are engaged with each other.

[0056] Furthermore, the bending part includes a fixed block 1001, a limiting bar 1002, a mounting plate 1003, an electric push rod 1004, a clamping block 1005 and a clamping piece 1006. The fixed block 1001 is fixed on the mounting seat 10, the limiting bar 1002 is fixed on two opposite sides of the top surface of the fixed block 1001, the mounting plate 1003 is fixed on the side wall of the fixed block 1001, the electric push rod 1004 is fixed on the side wall of the mounting plate 1003, the clamping block 1005 is fixed on the output end of the electric push rod 1004, the clamping block 1005 is slidably sleeved with the limiting bar 1002, and the clamping piece 1006 is fixed on the clamping block 1005.

[0057] Furthermore, the side ends of the clamping piece 1006 are provided with curved surfaces that align with the outer curved surface of the pipe body 6. This curved surface design allows the clamping piece 1006 to fit more closely against the surface of the pipe body 6, thereby increasing clamping stability and friction, and preventing the pipe body 6 from slipping or falling off during the bending process. When the clamping piece 1006 is subjected to external force, its curved surface presses tightly against the outer curved surface of the pipe body 6, forming an effective clamp.

[0058] Furthermore, an annular abutment surface is provided in the middle of the abutment roller 81, which matches the different curved surfaces of the pipe body. The annular abutment surface has a curvature and shape that matches the corresponding part of the pipe body 6, ensuring that the abutment roller 81 can accurately abut against the pipe body 6 and apply the necessary pressure to stably complete the bending operation.

[0059] The functional principle of this utility model can be explained through the following operation modes:

[0060] When using the bending machine, first place the pipe body 6 to be bent between the two clamping blocks 5 and fit it against the side wall of the abutting roller 81. Manually rotate the rocker 42 to drive the double-headed screw 41 to rotate in the slide groove 31. When the double-headed screw 41 rotates, the sliders 4 symmetrical on both sides immediately cooperate with the double-headed screw 41 threads and slide toward both ends of the pipe body 6 at the same time. As the sliders 4 slide, the clamping blocks 5 approach the pipe body 6, the clamping ring 53 contacts the pipe body 6, and begins to compress the spring 52. After being compressed, the spring 52 generates an outward clamping force, which firmly clamps the pipe body 6 between the clamping rings 53, so that the pipe body 6 is reinforced when it is bent, so that the pipe body 6 is always located on the inner side of the clamping ring 53 during the deformation process and will not bounce outward. In addition, pipes of different diameters can be reinforced, thereby improving the scope of application.

[0061] Start the electric push rod 1004 to extend and drive the clamping block 1005 to slide horizontally along the limit bar 1002. The clamping ring at the side end of the clamping block 1005 then fits against the side wall of the pipe body 6, so that the required bending position is reinforced again. Then start the second motor 91 to drive the transmission shaft 92 to drive the driving gear 93 to rotate. When the driving gear 93 rotates, it engages with the driven gear 94. The driven gear 94 is forced to drive the rotating column 9 to rotate around the pillar 8. At the same time, the mounting seat 10 outside the rotating column 9 also rotates along the outside of the pillar 8, so that the pipe with pressure applied to one end of the clamped pipe rotates along the annular abutment surface of the abutting wheel 81, so that the pipe body 6 is bent to the corresponding angle and the bending operation is completed, thereby effectively improving the processing efficiency of the equipment. In addition, this method can ensure the bending quality of the pipe.

[0062] When it is necessary to bend other positions of the pipe body 6 after bending one place, the electric push rod 1004 is turned off and contracted to drive the clamping block 1005 to reset and disengage from the pipe body 6, and the first motor 32 is started to drive the screw rod 33 to rotate. When the screw rod 33 rotates, the T-shaped slide 3 with its external thread sleeve immediately drives the clamped pipe body 6 to slide forward continuously. After sliding to the required bending position, the electric push rod 1004 is driven again to drive the clamping block 1005 to clamp the bent pipe body and bend it again, so that the pipe can be bent continuously without manual repeated picking up of the pipe for bending operations, thereby improving the flexibility of use.

[0063] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
