[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets to ensure the stability and integrity of the structure.

[0003] Currently, existing bending machines mainly consist of a frame, bending arm, bending roller, hydraulic cylinder, and pressure roller. Multiple pressure rollers are installed on the bending arm, and the steel pipe is placed between the pressure roller and the bending roller. Then, the hydraulic cylinder pulls the bending arm to rotate, and the steel pipe adheres to the surface of the pressure roller, causing it to bend and deform around the surface of the pressure roller, thereby completing the bending of the steel pipe.

[0004] During bending, workers need to mark the steel pipes to ensure that the insertion depth of each steel pipe is consistent, thereby ensuring that the position of the bending point of the steel pipe is consistent. However, the above bending method is inconvenient. Therefore, a steel structure processing bending machine is proposed to address the above problems. Utility Model Content

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-3 As shown, a steel structure processing bending machine includes a frame 11. A vertical plate 12 is provided at the top of the frame 11. A rotating shaft 15 is rotatably connected to the side of the vertical plate 12. A bending arm 13 is fixedly connected to the rotating shaft 15. A bending wheel 14 is installed at the end of the rotating shaft 15. Multiple pressure rollers 23 are installed on the bending arm 13. A drive assembly for driving the rotating shaft 15 to rotate is installed on the side of the bending arm 13. A screw 17 is rotatably connected to the end of the bending arm 13. An adjusting seat 18 is threadedly connected to the screw 17. A limit seat 19 is installed on the side of the adjusting seat 18. The drive assembly includes a hydraulic cylinder 16 and a swing arm. The swing arm is fixedly connected to the end of the rotating shaft 15. The hydraulic cylinder 16 is rotatably connected to the bottom side wall of the vertical plate 12. The output end of the hydraulic cylinder 16 is rotatably connected to the end of the swing arm.

[0025] In use, the steel pipe is inserted and placed on the bending wheel 14, which is located below the pressure wheel 23. Then, the hydraulic cylinder 16 pulls the swing arm, which in turn causes the swing arm and the rotating shaft 15 to rotate, thereby driving the bending arm 13 and the pressure wheel 23 to rotate, thus causing the steel pipe to rotate and completing the bending of the steel pipe. During the insertion of the steel pipe, the limiting seat 19 set at the end of the bending arm 13 can limit the insertion length of the steel pipe. The bending point of the steel pipe is fixed to the bending wheel 14, thereby positioning the bending position of the steel pipe, which is convenient for the operator to use. The position of the adjusting seat 18 and the limiting seat 19 can be adjusted by rotating the screw 17.

[0026] Furthermore, such as Figure 2-3 As shown, an electric actuator 21 is fixedly connected to the side of the adjusting seat 18, and a connecting seat 22 is fixedly connected to the output end of the electric actuator 21. The connecting seat 22 and the limiting seat 19 are fixedly connected. In use, the electric actuator 21 can push the connecting seat 22, causing the limiting seat 19 to move a certain distance and separate from the end of the steel pipe. When the bending arm 13 is reset, it can avoid the limiting seat 19 from sticking to the end of the steel pipe and being unable to reset.

[0027] Furthermore, such as Figure 2-3 As shown, a plurality of guide rods 41 are fixedly connected to the end of the bending arm 13, and sliding sleeves 42 are fixedly connected to the connecting seat 22 and the adjusting seat 18 at positions corresponding to the guide rods 41. The guide rods 41 pass through the sliding sleeves 42 and are slidably connected to them.

[0028] During use, the sliding sleeve 42 on the adjusting seat 18 and the connecting seat 22 slides on the guide rod 41, which can guide the adjusting seat 18 and the connecting seat 22, improve the stability of the adjusting seat 18 and the connecting seat 22, and improve the stability of the limiting seat 19.

[0029] Furthermore, such as Figure 1 and 4 As shown in Figure 5, a bracket 51 is fixedly connected to the side of the upright plate 12 away from the limiting seat 19. Multiple drive shafts 52 are fixedly connected to the top of the bracket 51. Drive wheels 53 are fixedly connected to the drive shafts 52. A reduction motor 54 is fixedly connected to the upright plate 12. A chain is installed between the output end of the reduction motor 54 and the drive shaft 52.

[0030] In use, the output end of the geared motor 54 and the drive shaft 52 are connected by a chain drive, which causes the drive shaft 52 to rotate, thereby causing the drive wheel 53 to rotate. The rotation of the drive wheel 53 is used to transport the steel pipe, which facilitates the transport of the steel pipe and allows the bent steel pipe to be unloaded after bending.

[0031] Furthermore, such as Figure 4As shown, a support 61 is fixedly connected to the top of the bracket 51, a steel brush cylinder 62 is rotatably connected to the support 61, and a drive shaft 63 is rotatably connected to the support 61. Both the end of the drive shaft 63 and the end of the drive shaft 52 are fixedly connected to bevel gears 64, which mesh with each other. Both the drive shaft 63 and the steel brush cylinder 62 are fixedly connected to spur gears 65, which mesh with each other.

[0032] In use, the drive shaft 52 rotates, and the bevel gear 64 on the drive shaft 52 meshes with the bevel gear 64 on the transmission shaft 63. Then, the transmission is carried out by the gear at the end of the transmission shaft 63 and the spur gear 65 on the steel brush cylinder 62, thereby driving the steel brush cylinder 62 to rotate. The steel pipe is inserted into the middle of the steel brush cylinder 62, and the rotation of the steel brush cylinder 62 cleans the surface of the steel pipe and removes some foreign objects, thus cleaning the steel pipe and removing foreign objects from the surface of the steel pipe.

[0033] Furthermore, such as Figure 1 As shown, a handwheel 7 is fixedly connected to the end of the screw 17. In use, the screw 17 can be rotated by the handwheel 7, which makes it convenient for the operator to use.

[0034] Working principle: During use, the steel pipe is inserted and placed on the bending wheel 14, which is located below the pressure wheel 23. Then, the hydraulic cylinder 16 pulls the swing arm, causing the swing arm and the rotating shaft 15 to rotate, thereby driving the bending arm 13 and the pressure wheel 23 to rotate, thus rotating the steel pipe and completing the bending of the steel pipe. During the insertion of the steel pipe, the limiting seat 19 at the end of the bending arm 13 can limit the insertion length of the steel pipe, and the bending point of the steel pipe is fixed to the bending wheel 14, thereby positioning the bending position of the steel pipe for easy use by the operator. The position of the adjusting seat 18 and the limiting seat 19 can be adjusted by rotating the screw 17. The sliding sleeve 42 on the adjusting seat 18 and the connecting seat 22 slides on the guide rod 41, thereby guiding the adjusting seat 18 and the connecting seat 22 and improving the adjustment. The stability of the joint seat 18 and the connecting seat 22 is improved, and the stability of the limit seat 19 is enhanced. The output end of the reduction motor 54 and the drive shaft 52 are connected by a chain drive, which causes the drive shaft 52 to rotate, thereby causing the drive wheel 53 to rotate. The rotation of the drive wheel 53 is used to rotate and transport the steel pipe, which facilitates the transport of the steel pipe. After bending, the bent steel pipe is unloaded. The drive shaft 52 rotates, and the bevel gear 64 on the drive shaft 52 meshes with the bevel gear 64 on the transmission shaft 63. Then, the gear at the end of the transmission shaft 63 and the spur gear 65 on the steel brush cylinder 62 are used for transmission, thereby driving the steel brush cylinder 62 to rotate. The steel pipe is inserted into the middle of the steel brush cylinder 62, and the rotation of the steel brush cylinder 62 cleans the surface of the steel pipe and removes some foreign objects, thus cleaning the steel pipe and removing foreign objects from the surface of the steel pipe.
