[0002] Steel pipes are indispensable materials in automobile manufacturing, oil and gas transportation, building materials and aerospace. In order to ensure the straightness of steel pipes, curved steel pipes will be straightened by straightening machines to remove the curvature of the steel pipes and improve their straightness.

[0003] Because the existing steel pipes are not surface pretreated before straightening, a large amount of debris is carried into the straightening equipment, affecting the service life of the straightening equipment. In addition, because the steel pipes are heated before straightening, the residual stress after straightening is large, which can easily cause the steel pipes to deform or crack during later use. Therefore, a steel pipe straightening machine feeding device is proposed to provide a set of steel pipe pretreatment mechanisms for the feeding end of the steel pipe straightening machine, which can pre-clean and pre-heat the surface of the steel pipe. The pre-cleaning can improve the cleanliness of the steel pipe surface and improve the quality of the steel pipe in use. Summary of the invention

[0015] Specifically, the inner cavity of the first rectangular cover is provided with a groove corresponding to the heating coil, the heating coil is located in the groove, and the coil end of the heating coil does not contact the first rectangular cover.

[0016] By adopting the above technical solution, preheating can improve the plasticity of the steel pipe, making it easier for the steel pipe to deform into a predetermined shape, reducing the resistance and stress concentration during the straightening process, and facilitating a more precise straightening effect.

[0017] Specifically, the second rectangular cover is a hollow structure, dust inlet holes are provided on both sides of the inner wall of the second rectangular cover, and the dust inlet end of the suction part is connected to the second rectangular cover through a pipe.

[0038] The heating coil 206 is disposed on the first rectangular cover 201 .

[0039] When in use, the steel pipe passing through the first rectangular cover 201 is heated by the heating coil 206, so that the heated steel pipe has better plasticity after entering the steel pipe straightening machine 1, thereby reducing the resistance and stress concentration of the steel pipe during the straightening process.

[0040] For example, Figure 1-4As shown, the utility model also includes that the inner cavity of the first rectangular cover 201 is provided with a groove 204 corresponding to the heating coil 206 , the heating coil 206 is located in the groove 204 , and the coil end of the heating coil 206 does not contact the first rectangular cover 201 .
