Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, specifically a pipe bending machine with feeding and straightening function. Background Technology

[0002] Pipe bending machines are machines used for bending pipes and can also be used as jacks. They are generally divided into CNC pipe bending machines and hydraulic pipe bending machines, and are used in pipeline laying and repair in power construction, railway and highway construction, bridges, ships and other fields.

[0003] Existing feeding devices often suffer from vibration, inaccurate initial placement, and a lack of effective positioning constraints, leading to positional deviations in the metal tubes.

Therefore, a tube bending machine with feeding correction function is proposed. Utility Model Content

Example

[0032] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the bending mechanism 3 includes a bending block 32, a fixed plate 31 is fixedly installed on the top surface of the base plate 1, an electric telescopic rod 36 is fixedly installed on the back of the fixed plate 31, the front of the output end of the electric telescopic rod 36 extends through the back of the fixed plate 31 to the front of the fixed plate 31, the front of the output end of the electric telescopic rod 36 is fixedly connected to the back of the bending block 32, a movable frame 34 is slidably installed on the top surface of the base plate 1, two rotating rollers 33 are rotatably installed on the upper and lower end faces of the inner side of the movable frame 34 through two bearing seats, the rotating rollers 33 are located in front of the bending block 32, a fixed frame 311 is fixedly installed on the top surface of the base plate 1, and a connecting block 31 is fixedly installed on the left side of the movable frame 34. 0. The surface of the connecting block 310 is slidably connected to the inner side of the fixed frame 311. The top surface of the connecting block 310 has a threaded hole. The top surface of the fixed frame 311 has a through groove. The inner wall of the through groove is provided with a bolt 39. The bottom surface of the bolt 39 extends to the inner wall of the threaded hole and is threadedly connected to the inner wall of the threaded hole. The surface of the bolt 39 is fixedly fitted with a compression ring 38. The bottom surface of the compression ring 38 contacts the top surface of the fixed frame 311. The top surface of the base plate 1 has a wedge-shaped groove. The inner wall of the wedge-shaped groove is slidably provided with a wedge-shaped block 35. The top surface of the wedge-shaped block 35 is fixedly connected to the bottom surface of the moving frame 34. The back of the bending block 32 is fixedly provided with two limiting plates 37. The back of the two limiting plates 37 slides through the front of the fixed plate 31 and extends to the rear of the fixed plate 31.

[0033] In this embodiment, the movable frame 34 in the bending mechanism 3 can be moved manually. After the rotating roller 33 contacts the metal tube, it is fixed with bolts 39 and extrusion ring 38, which can flexibly adapt to the bending requirements of metal tubes of different diameters and improve versatility. The electric telescopic rod 36 precisely controls the stroke of the bending block 32, which can be bent accurately to ensure accuracy and quality. The movable frame 34 is slidably connected to the fixed frame 311 through the connecting block 310 and the wedge block 35 cooperates with the wedge groove of the base plate 1. The structure is stable and prevents shaking from causing bending errors, meeting the requirements of high-precision bending products.

[0034] In use, the metal pipe to be bent is placed above the conveyor belt 21. After the conveyor belt 21 is turned on, the metal pipe is transported. During the transport of the metal pipe, the motor 29 is turned on. When the output end of the motor 29 rotates, it can drive the threaded rod 27 to rotate. During the rotation of the threaded rod 27, the lifting plate 214 can drive the lifting frame 215 to move up and down. When the lifting frame 215 moves upward, it can drive the two inclined blocks 212 to move upward synchronously. When the two inclined blocks 212 move upward, they can squeeze the two arc plates 210. The two arc plates 210 under pressure will move towards the middle. When the two arc plates 210 move, they can obtain two extrusion frames 24 and two sets of rollers 23 to move synchronously. When the two sets of rollers 23 move closer to the middle, the position of the metal pipe can be corrected so that it can be in the middle position of the conveyor belt 21.

[0035] The moving frame 34 is moved manually until the surface of the rotating roller 33 contacts the surface of the metal pipe and is then fixed. During fixing, the bolt 39 is tightened manually so that the bottom surface of the extrusion ring 38 contacts the top surface of the fixed frame 311, thereby fixing the moving frame 34 and the rotating roller 33. When the metal pipe is moved to the position where it needs to be bent, the conveyor belt 21 is turned off. The bending block 32 can be moved forward by opening the electric telescopic rod 36. During the forward movement of the bending block 32, the pipe can be bent.

[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
