[0024] It should be noted that, in the description of the present invention, terms such as "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0025] See also Figures 1 to 6The figure shows a schematic diagram of a preferred embodiment of the utility model. The utility model is related to a pipe bending and rib-forming machine, which includes a machine base 1, a rotating shaft 2, a supporting member 3 and a rib-forming wheel 5. The machine base 1 of the embodiment is horizontally arranged and forms a table, on which a boss 11 protruding upward is provided. The rotating shaft 2 is rotatably assembled on the machine base 1, the rotating shaft 2 is vertically arranged, and the lower end of the rotating shaft 2 is connected to the driving motor 7, so that the rotating shaft 2 can rotate under the drive of the driving motor 7. In the embodiment, a sprocket is installed at the lower end of the rotating shaft 2, and the driving motor 7 is connected through the sprocket matching chain, so that the driving motor 7 drives the rotating shaft 2 to rotate. The structure is simple, convenient to manufacture and maintain, and the investment cost is low. In the embodiment, the upper end of the rotating shaft 2 extends upward from the inner middle part of the boss 11, and the rotating shaft 2 is connected to the boss 11 through a bearing, which improves the assembly structure and use effect of the rotating shaft 2. A positioning ring 21 and a forming convex ring 22 are provided on the part of the rotating shaft 2 protruding from the boss 11; the outer diameter of the positioning ring 21 is larger than the outer diameter of the forming convex ring 22, so that when the bent pipe 4 is sleeved on the rotating shaft 2, the end of the bent pipe 4 is supported on the positioning ring 21 to determine the insertion depth and obtain the placement posture. At the same time, the forming convex ring 22 is embedded in the inner side of the bent pipe 4 for subsequent molding processing. The supporting member 3 is installed on the machine base 1 and is located on one side of the boss 11. When the bent pipe 4 is sleeved on the rotating shaft 2, the placement posture of the bent pipe 4 is stabilized by the supporting member 3, solving the problem of eccentric placement of the bent pipe 4, and allowing the forming part of the bent pipe to be close to the forming convex ring 22, preventing the eccentric deviation of the bent pipe during the rotation process, and ensuring the subsequent processing speed and quality.

[0026] The rib wheel 5 is rotatably mounted on the moving mechanism 6, which is assembled on the machine base 1, so that the moving mechanism 6 can drive the rib wheel 5 to approach or move away from the rotating shaft 2; the rib wheel 5 and the rotating shaft 2 form a roller-type working, and a rib ring groove 51 and an avoidance groove 52 located at the lower side of the rib ring groove 51 are provided on the outer periphery of the rib wheel 5. When the rib wheel 5 and the rotating shaft 2 roll relative to each other, the rib ring groove 51 cooperates with the forming convex ring 22 to extrude the bent pipe 4, so that the bent pipe 4 forms ribs; and the avoidance groove 52 provides an avoidance space for the positioning ring 21 to follow the movement, prevent work interference, and promote production. In this embodiment, the rib ring groove 51 and the forming convex ring 22 are both V-shaped structural systems, so that the rib ring groove 51 and the forming convex ring 22 form an inner and outer cooperation to extrude the bent pipe 4 to form ribs.

[0027] During operation, the bent pipe 4 is sleeved on the rotating shaft 2, and the placement posture of the bent pipe 4 is stabilized by the support member 3. Then, the moving mechanism 6 drives the rib wheel 5 to approach the rotating shaft 2, so that the rib ring groove 51 cooperates with the forming convex ring 22 to squeeze the bent pipe 4, and the rib wheel 5 maintains continuous abutment and top pressure. In this way, the driving motor 7 drives the rotating shaft 2 to rotate and drives the bent pipe 4 to rotate. The rib ring groove 51 cooperates with the forming convex ring 22 to form a circle of ribs on the bent pipe 4, realizing that machinery replaces manual work, improving production efficiency, and reducing personnel costs. After processing is completed, the moving mechanism 6 drives the rib wheel 5 away from the rotating shaft 2. At this time, the support member 3 is pulled to remove the processed bent pipe 4 from the rotating shaft.

[0028] Figures 1 to 6 As shown, in this embodiment, the support member 3 is an L-shaped pressure plate, one end of the support member 3 is connected to the machine base 1 through a hinge 31, so that the support member 3 can open and close relative to the machine base 1, so as to facilitate the assembly and disassembly of the bending pipe; the other end of the support member 3 forms a hook head 32, which is pulled by an elastic member 33 and leans against the rotating shaft 2, and an arc-shaped opening 321 is provided on the hook head 32, through which the bending pipe 4 is supported by leaning against the outer peripheral surface of the bending pipe, that is, a supporting fulcrum is added to the bending pipe, the problem of eccentricity of the bending pipe is solved, and the bending pipe is ensured to be stably sleeved on the rotating shaft, and at the same time, the forming part of the bending pipe can be close to the forming convex ring 22. The elastic member 33 pulls and holds, so that the support member 3 can continuously support the bending pipe, and the characteristics of the arc-shaped opening 321 can be used to meet the rotation of the bending pipe without deviation.

[0029] In this embodiment, the position of the arc-shaped opening 321 that contacts the bent pipe is higher than the height position of the forming convex ring 22, forming a superior-feeble relationship, and the direction in which the arc-shaped opening 321 contacts the bent pipe forms an angle with the direction in which the rib wheel 5 contacts the rotating shaft 2 to form a pair of rollers, and the size of the angle is between 90° and 180°. This not only effectively ensures the roller forming process, but also supports the bent pipe based on the principle of leverage, ensuring that the bent pipe rotates smoothly and does not deviate, thereby improving the processing speed and quality.

[0030] Figures 1 to 6 As shown, in this embodiment, the moving mechanism 6 includes a moving seat 61 and a power member 62. The moving seat 61 is installed on the machine base 1 through a linear guide rail to ensure smooth and accurate movement; the power member 62 is positioned on the machine base 1 and pushes and pulls the moving seat 61 close to or away from the rotating shaft 2, and the rib wheel 5 is rotatably installed on the end of the moving seat 61 close to the rotating shaft 2. The power member 62 is a cylinder, oil cylinder or motor screw assembly, and can adapt to different thicknesses of bending pipe forming processing by adjusting the stroke of the moving seat 61, and has a wide range of applications.

[0031] The utility model works by the rib raising wheel and the rotating shaft rolling relative to each other, and the rib raising ring groove cooperates with the forming convex ring to extrude the bent pipe, so that the bent pipe is formed with ribs; the rotating shaft is driven to rotate by a driving motor, so that machinery replaces manual work, improves production efficiency, reduces personnel costs, and meets the needs of modern automated production. At the same time, a supporting part is added. When the bent pipe is sleeved on the rotating shaft, the placement posture of the bent pipe is stabilized by the supporting part, so that the forming part of the bent pipe is close to the forming convex ring to prevent the bent pipe from eccentric deviation during the rotation process, and ensure the speed and quality of the roller-formed ribs. Although this embodiment uses the bent pipe as an example to illustrate the processing and production, it is of course also suitable for the production of straight pipes, and is not limited here.

[0032] Although the preferred specific embodiments of the present invention are described above in conjunction with the accompanying drawings, the present invention should not be limited to the structures and operations that are exactly the same as the above description and the accompanying drawings. For those skilled in the art, many equivalent improvements and changes can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and changes should all fall within the scope of protection required by the present invention.
