[0002] A steel pipe straightening machine is a mechanical device used to straighten metal profiles, bars, pipes, and wires. It primarily uses straightening rollers to compress the raw materials, thereby changing their straightness. Currently, after straightening, the steel pipes need to be removed from the guide rails of the straightening machine. During this removal process, the surface of the steel pipes is prone to wear, affecting the quality of the pipes and resulting in pipe loss. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multi-roller straightening and pushing device that is easy to operate, can push the steel pipe out of the guide frame, facilitate the unloading of the steel pipe, reduce the wear on the surface of the steel pipe, and ensure the quality of the steel pipe.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a multi-roller straightening and pushing device, including a rotating shaft unit, which is arranged on the side of the guide groove frame; the rotating shaft unit is provided with an active pushing arm and a plurality of driven pushing arms, the active pushing arms and the driven pushing arms are evenly spaced, the active pushing arm is provided with a pushing drive device on its side, the pushing drive device is hinged to the frame, the pushing drive device is fixedly connected to the active pushing arm, the pushing drive device drives the active pushing arm to swing, which drives the rotating shaft unit to swing, so that the plurality of driven pushing arms swing synchronously, thereby pushing the steel pipe out from the inside of the guide groove frame.

[0005] The rotating shaft unit includes multiple horizontally arranged rotating shafts, which are fixedly connected to each other by couplings. The rotating shafts are respectively fixed to the outer side of the guide slot frame by bearing seats.

[0006] Liners are provided on the inner sides of the active feeding arm and the driven feeding arm, respectively.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , 2 As shown in Figures 3 and 4, this embodiment includes a multi-roller side-pushing and pulling device. The side-pushing and pulling device is located on one side of the guide rail frame 10 of the straightening machine. It pushes and pulls the steel pipes inside the guide rail frame 10 out of the straightening station. The side-pushing and pulling device includes multiple horizontally arranged rotating shafts 2, which are fixedly connected to adjacent rotating shafts 2 via couplings 3, forming a rotating shaft unit. The rotating shafts 2 are respectively fixed to the outer side of the guide rail frame 10 via bearing seats 5, allowing the rotating shafts 2 to rotate within the bearing seats 5. The rotating shaft unit is equipped with an active material-pushing arm 4 and multiple driven material-pushing arms 1, which are evenly spaced. A pushing cylinder 7 is provided on the side of the active material-pushing arm 4, and the pushing cylinder 7 is hinged to the frame 6. A connecting ear plate 8 is provided on the outer side of the active material-pushing arm 4, and the extension rod of the pushing cylinder 7 is fixedly connected to the connecting ear plate 8 via a pin 11. The pusher cylinder 7 drives the active material feeding arm 4 to swing, which in turn drives the rotating shaft unit to rotate, causing multiple driven material feeding arms 1 to swing synchronously, thereby pushing the steel pipe out from the inside of the guide slot frame 10, so that the steel pipe leaves the straightening station.

[0017] The inner sides of the driven material feeding arm 1 and the inner sides of the active material feeding arm 4 are respectively fixedly connected to the liner plate 9 by bolts. During the side pushing process, the steel pipe and the liner plate 9 are in surface contact, which not only reduces the wear on the surface of the steel pipe, but also prevents the active and driven material feeding arms from wearing with the steel pipe, thus improving the service life of the active and driven material feeding arms; only the liner plate needs to be replaced.

[0018] This application is easy to operate. The steel pipe is pushed out by the active and passive push arms. During the pushing process, the steel pipe and the liner are in surface contact, which reduces the wear on the steel pipe surface and ensures the surface quality of the steel pipe.

[0019] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
