Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically to a conveying device for a pipe bending machine used in hardware processing production. 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] During the operation of a pipe bending machine, metal pipes need to be conveyed; a conveying device is required during this process.

A sliding groove is opened through the front of the fixed frame 21, and a control frame 212 is slidably installed on the inner wall of the sliding groove. A fixed frame 213 is fixedly installed on the front of the fixed frame 21. The control frame 212 is located inside the... The side is slidably connected to the surface of the fixed frame 213. The front of the control frame 212 is threaded with a bolt 214 extending to the inside of the fixed frame 213. The top surface of the lifting frame 28 is fixedly provided with two limiting plates 23. The top surfaces of the two limiting plates 23 slide through the top surface of the inner side of the fixed frame 21 and extend to the top of the fixed frame 21. The top surface of the base plate 1 is fixedly provided with two guide rails 29.

Example

[0036] like Figures 1-6 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the auxiliary mechanism 3 includes two extrusion frames 31, the bottom surfaces of the two extrusion frames 31 are slidably connected to the top surface of the base plate 1, the inner sides of the two extrusion frames 31 are respectively provided with two sets of rollers 33 through two sets of bearing seats, the left and right ends of the base plate 1 are respectively fixedly provided with two connecting frames 32, the left and right ends of the two extrusion frames 31 are respectively fixedly provided with two sets of springs 36 and two sets of dampers 35, the opposite sides of the two sets of springs 36 and the two sets of dampers 35 are respectively fixedly connected to the inner sides of the two connecting frames 32, the opposite sides of the two extrusion frames 31 are respectively fixedly provided with two sets of limiting rods 34, the opposite sides of the two sets of limiting rods 34 slide through the inner sides of the two connecting frames 32 and extend to the outside of the two connecting frames 32.

[0037] In this embodiment, the rollers 33 of the auxiliary mechanism 3 can effectively assist in limiting the movement of the metal pipe during transport, ensuring transportation stability and preventing shaking or deviation from the path. Furthermore, with the help of the spring 36 and damper 35, the distance between the rollers 33 can be automatically adjusted to accommodate metal pipes of different diameters, improving the applicability of the device and ensuring efficient pipe bending operations.

[0038] In use, the metal tube to be bent is placed on the surface of the rotating roller 25. The nut 219 is rotated manually. When the nut 219 rotates, the two moving plates 216 can move left and right through the threaded rod 215. When the two moving plates 216 move left and right, the two sliding sleeves 210 can move in opposite directions through the two push rods 24. During the movement of the two sliding sleeves 210, the two limiting rings 211 can move synchronously through the connecting rod 222, the moving frame 221, the connecting sleeve 220, and the ring rail. When the two limiting rings 211 approach each other, they can limit the metal tube. After the side of the two limiting rings 211 that are close to each other contacts the surface of the metal tube, the nut is stopped from rotating. Then the bolt 214 is tightened manually. After the bolt 214 is loosened, the pressure roller 26 can move downward by gravity, so that the surface of the pressure roller 26 contacts the surface of the metal tube. After contact, the bolt 214 is tightened manually, so that the back of the bolt 214 contacts the inner rear end face of the fixing frame 213, thereby fixing the pressure roller 26. After fixing is completed, the motor 22 is turned on. When the output end of the motor 22 rotates, the rotating roller 25 can rotate. During the rotation of the rotating roller 25, the metal tube can be conveyed. By setting two wedge blocks 27 and wedge grooves, the two limiting rings 211 can rotate synchronously with the rotating roller 25. During the rotation, the two ring rails and two guide rails 29 can ensure that the limiting rings 211 are not restricted during rotation.

[0039] During transportation, the surface of the metal tube will come into contact with the surfaces of the two sets of rollers 33, which can help limit the movement of the metal tube during transportation. Furthermore, the distance between the two sets of rollers 33 can be adjusted according to the diameter of the metal tube by means of two sets of springs 36 and two sets of dampers 35, making it suitable for metal tubes of different diameters.

[0040] 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.
