[0026] Please refer to Figures 1-5 , the present invention provides a technical solution: a hydraulic bending machine with a protection device, including a fixed frame 1, a bending assembly is installed on the top of the fixed frame 1; a protection assembly, the protection assembly is installed on the top of the fixed frame 1, and a support assembly is installed at one end of the top of the fixed frame 1.

[0027] In order to quickly complete the bending process of the pipe fitting, the bending assembly includes a hydraulic cylinder 2, a bent elbow 3 and two stop posts 4. The hydraulic cylinder 2 is installed at the other end of the top of the fixed frame 1, the bent elbow 3 is installed on the piston rod of the hydraulic cylinder 2, and the two stop posts 4 are respectively fixedly connected to both ends inside the bent elbow 3. A sizing die 5 is installed on the top of the fixed frame 1, and an arc groove 6 is opened on one side of the sizing die 5 adjacent to the bent elbow 3; by the extension of the piston rod of the hydraulic cylinder 2, the piston rod of the hydraulic cylinder 2 drives the bent elbow 3 to move. At this time, the two stop posts 4 on the bent elbow 3 respectively abut against the outside of the pipe fitting, and then the pipe fitting is moved into the arc groove 6 of the sizing die 5 to complete the bending of the pipe fitting.

[0028] By setting up the protection components, the safety of the bending machine can be improved; the protection components include two connecting seats 7, two rotating shafts 8 and two racks 9. The two connecting seats 7 are respectively fixedly connected to both sides of the bending head 3. The two rotating shafts 8 are rotatably connected to opposite ends of the two connecting seats 7. The two racks 9 are respectively fixedly connected to both sides of the top of the fixed frame 1. Gear 10 is fixedly sleeved on the outer sides of both rotating shafts 8. A protective cover 11 is installed on the outer sides of both rotating shafts 8 and located outside the gear 10. The gear 10 is located directly above the rack 9, and the gear 10 is meshed and connected to the top of the rack 9. During the movement of the bending head 3, the connecting seat 7 drives the rotating shaft 8 to move, so that the rotating shaft 8 drives the gear 10 to move above the rack 9. At this time, the gear 10 drives the rotating shaft 8 to rotate, thereby driving the protective cover 11 to rotate, so that it covers the outer sides of the bending head 3 and the shaping die 5, and can provide protection during the bending of the pipe fitting, preventing the pipe fitting from breaking and popping out and causing harm to personnel.

[0029] In order to facilitate the bending process of the pipe fitting; the support components include two guide posts 12, two placing seats 13 and a hollow bevel gear 15. The two guide posts 12 are fixedly connected to the top of the fixed frame 1. The two placing seats 13 are respectively slidably connected to the outer sides of the two guide posts 12. A threaded column 14 is rotatably connected to the bottom of the two placing seats 13. The hollow bevel gear 15 is rotatably connected to the bottom of the fixed frame 1 and is movably sleeved on the outer side of the threaded column 14. An adjusting component is installed at the bottom of the fixed frame 1. The hollow bevel gear 15 is threadedly connected to the outer side of the threaded column 14. The hollow bevel gear 15 rotates on the outer side of the threaded column 14, so that the placing seat 13 on the threaded column 14 moves upward on the outer side of the guide post 12, thereby adjusting the height of the pipe fitting, so that the pipe fitting moves to the outside of the arc-shaped groove 6 to facilitate the processing of the pipe fitting.

[0030] In order to facilitate the adjustment of the height of the placing seat 13; the adjusting component includes a fixing plate 16, a rotating shaft 17 and two bevel gears 18. The fixing plate 16 is fixedly connected to the bottom of the fixed frame 1. The rotating shaft 17 is rotatably connected to the outer side of the fixing plate 16. The two bevel gears 18 are fixedly connected to both ends of the rotating shaft 17. A worm gear 19 is fixedly sleeved on the outer side of the rotating shaft 17. A worm 20 is installed at the bottom of the fixed frame 1. The worm 20 is meshed and connected to the outer side of the worm gear 19. One end of the worm 20 is fixedly connected to a turntable. By placing the pipe fitting on the placing seat 13 and then rotating the turntable to drive the worm 20 to rotate, the worm 20 can drive the rotating shaft 17 to rotate through the worm gear 19, thereby driving the bevel gear 18 to rotate. The bevel gear 18 drives the hollow bevel gear 15 to rotate at the bottom of the fixed frame 1. The hollow bevel gear 15 rotates on the outer side of the threaded column 14, so that the placing seat 13 on the threaded column 14 moves upward on the outer side of the guide post 12, thereby adjusting the height of the placing seat 13.

[0031] Working principle or structural principle. Before bending the pipe fitting, place the pipe fitting on the placing seat 13, and then rotate the turntable to drive the worm 20 to rotate. The worm 20 can drive the rotating shaft 17 to rotate through the worm gear 19, thereby driving the bevel gear 18 to rotate. The bevel gear 18 drives the hollow bevel gear 15 to rotate at the bottom of the fixed frame 1. The hollow bevel gear 15 rotates outside the threaded column 14, so that the placing seat 13 on the threaded column 14 moves upward outside the guide post 12, thereby adjusting the height of the pipe fitting and moving the pipe fitting to the outside of the arc groove 6 for convenient processing of the pipe fitting;

[0032] When bending the pipe fitting, start the hydraulic station through the switch group, so that the piston rod of the hydraulic cylinder 2 extends. The piston rod of the hydraulic cylinder 2 drives the bending head 3 to move. At this time, the two side stoppers 4 on the bending head 3 respectively abut against the outside of the pipe fitting, and then move the pipe fitting into the arc groove 6 of the shaping die 5 to complete the bending of the pipe fitting. During the movement of the bending head 3, the connecting seat 7 drives the rotating shaft 8 to move, so that the rotating shaft 8 drives the gear 10 to move above the rack 9. At this time, the gear 10 drives the rotating shaft 8 to rotate, thereby driving the protective cover 11 to rotate, so that it covers the outside of the bending head 3 and the shaping die 5, which can provide protection during the bending of the pipe fitting, prevent the pipe fitting from breaking and popping out, causing harm to personnel, and improve the safety of the bending machine.
