[0002] In the field of pipe processing, bending machines are key equipment for bending and forming pipes, and their performance directly affects the quality and production efficiency of pipe products.
[0003] Based on the above, the inventors have discovered the following problems: Pipe materials, such as metal pipes and some engineering plastic pipes, possess a certain degree of rigidity and brittleness at room temperature. When they are bent, the pipes need to undergo plastic deformation to achieve the desired bending shape. However, without heating assistance, the stress on the pipes during bending is concentrated at the bending point, making it difficult to smoothly adjust the internal crystal structure of the material, which can easily lead to excessive local deformation or even cracking.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a bending mechanism for a bending machine in order to achieve a more practical purpose. Utility Model Content

[0024] The beneficial effect of adopting the above-mentioned further solution is that by slidingly installing the connecting seat on the upper end of the rotating seat and installing the second abutment on its upper end, it can cooperate with the third abutment to clamp the pipe, so that the pipe can be bent when the rotating seat rotates.
[0025] Furthermore, a fourth telescopic rod is installed on the side of the upper surface of the rotating seat away from the third abutment block, and one end of the fourth telescopic rod is connected to the connecting seat.

[0037] Please see Figure 1 - Figure 6A pair of wire clips 2009 are mounted on the outside of the mounting bracket 2001. A spring cable 2006 is provided between the pair of wire clips 2009. The two ends of the spring cable 2006 are connected to the input end of the heating coil 2004 and the output end of the high-frequency induction heater 1010, respectively. A first servo motor 2008 is fixedly mounted on the upper end of the mounting bracket 2001. The output end of the first servo motor 2008 is connected to the screw 2002 for transmission. A second servo motor 3005 is mounted on the outside of one end of the pneumatic chuck 3002. A first gear 3006 is sleeved on the output end of the second servo motor 3005. A gear disk 3004 is sleeved on one end of the internal rotating shaft of the pneumatic chuck 3002. The gear disk 3004 and the first gear 3006 mesh with each other. The housing 10 A movable frame 1008 is installed on one side of the upper end face of housing 1001. A movable block 1016 is slidably installed inside the movable frame 1008. A second telescopic rod 1013 is installed on the upper end of the movable block 1016. A movable frame 1014 is slidably installed on the outer side of the second telescopic rod 1013. One end of the second telescopic rod 1013 is connected to the inner side of the movable frame 1014. A first abutment 1015 is installed on one side of the movable frame 1014. A third telescopic rod 1020 is inserted into one end of the movable frame 1008. One end of the third telescopic rod 1020 is connected to the movable block 1016. A pair of third servo motors 1017 are fixedly installed on the upper end face of housing 1001 on one side of the movable frame 1008. Each output end of the third servo motor 1017 is fitted with a connecting plate 1018. Guide wheels 1019 are rotatably connected to one side of the upper end of the connecting plate 1018.

A first servo motor 2008 is installed to drive the screw 2002 to rotate. A second servo motor 3005 is installed to drive the first gear 3006 to rotate. The first gear 3006 meshes with a gear disc 3004 mounted on the rotating shaft of the pneumatic chuck 3002, thereby driving the rotating shaft of the pneumatic chuck 3002 to rotate, thus causing the clamped pipe to rotate.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Please see Figure 1 - Figure 6A movable seat 1002 is installed at one end of the housing 1001. A rotating seat 1003 is rotatably sleeved at one end of the movable seat 1002. A connecting shaft 1009 is rotatably connected inside the movable seat 1002. The upper end of the connecting shaft 1009 is connected to the central shaft of the rotating seat 1003. A second gear 1011 is sleeved on the connecting shaft 1009. A rack 1012 is slidably inserted into one side of the movable seat 1002 at one end of the housing 1001. The rack 1012 meshes with the second gear 1011. The housing 1001 has a hydraulic rod installed on one side inside, with one end connected to one end of the rack 1012. A connecting seat 1006 is slidably mounted on the upper side of the rotating seat 1003. A second abutment 1007 is mounted on the upper end of the connecting seat 1006. A third abutment 1004 is mounted on the upper end of the rotating seat 1003, on the side opposite to the second abutment 1007. A fourth telescopic rod 1005 is mounted on the upper surface of the rotating seat 1003, away from the third abutment 1004. One end is connected to the connecting seat 1006. A rotating seat 1003 is rotatably fitted onto one end of the movable seat 1002 to facilitate its rotation. The connecting guide tube of the connecting shaft 1009 is connected to the central axis of the rotating seat 1003. When the connecting shaft 1009 rotates, the rotating seat 1003 also rotates. A hydraulic rod is installed so that it can drive the slidingly connected rack 1012 to extend and retract during operation. The rack 1012 meshes with the second gear 1011 fitted onto the connecting shaft 1009, thereby enabling… The rotating seat 1003 is rotated. A connecting seat 1006 is slidably installed on the upper end of the rotating seat 1003, and a second abutment 1007 is installed on its upper end. This, together with the third abutment 1004, can clamp the pipe. Thus, when the rotating seat 1003 rotates, the pipe can be bent. By installing a fourth telescopic rod 1005, it can drive the connecting seat 1006 to move when it is working, so that the second abutment 1007 moves closer to the third abutment 1004, thereby clamping the pipe.
[0040] Specifically, the working principle of the bending mechanism of this type of bending machine is as follows: During use, based on the pipe size and heating position requirements, the first servo motor 2008 is activated. The first servo motor 2008 drives the screw 2002 to rotate. Since the slider 2003 is threadedly connected to the screw 2002 and is connected to the adjusting frame 2005, the rotation of the screw 2002 causes the slider 2003 to move up and down along the screw 2002, thereby causing the adjusting frame 2005 to slide up and down on the mounting frame 2001, achieving vertical position adjustment of the heating coil 2004. Then, the first telescopic rod 2007 extends and retracts, pushing the heating coil 2004 on the adjusting frame 2005. The heating coil 2004 is adjusted by sliding back and forth to ensure it is accurately aligned with the part of the pipe to be heated. During this process, the spring cable 2006 extends and retracts with the movement of the heating coil 2004 under the limiting action of a pair of clamps 2009, maintaining the electrical connection between the high-frequency induction heater 1010 and the heating coil 2004. The pipe is placed in the pneumatic chuck 3002, which is then activated to clamp the pipe. The linear motor 3001 then starts, driving the clamp 3003, the pneumatic chuck 3002, and the clamped pipe for linear transport. During the feeding process, the second servo motor 300 is activated. 5. Upon startup, the first gear 3006 at its output end rotates, meshing with the gear disk 3004 at one end of the internal rotating shaft of the pneumatic chuck 3002. This drives the rotating shaft to rotate, causing the clamped tube to rotate around its own axis. This allows the tube to move to the bottom of the heating coil 2004 for uniform heating, and also facilitates bending the tube at different angles. After heating ends, the linear motor 3001 continues to push the tube. At this time, the third telescopic rod 1020 pushes the moving block 1016, which in turn drives the second telescopic rod 1013 to move back and forth. The second telescopic rod 1013 pushes the moving frame 1014 to move, and the first abutment block 1015 moves accordingly, providing support during tube bending. Once the tube reaches... When the second abutment 1007 and the third abutment 1004 are between each other, the hydraulic rod pushes the rack 1012 to move. The rack 1012 meshes with the second gear 1011 on the connecting shaft 1009, causing the connecting shaft 1009 to rotate, which in turn causes the rotating seat 1003 to rotate. The fourth telescopic rod 1005 pushes the connecting seat 1006 to move. The second abutment 1007 moves closer to the third abutment 1004 to clamp the pipe. The rotating seat 1003 rotates to achieve pipe bending. A pair of third servo motors 1017 drive the connecting plate 1018 to rotate and control the guide wheel 1019 to open and close. When the pipe is long, the two sides are clamped to ensure stable delivery. When the pipe is short, the position is cleared to facilitate the push of the pneumatic chuck 3002.
