With the continuous improvement of the production quality and the decline of the price of steel pipes, and the in-depth understanding of a series of benefits brought by the high performance-price ratio of construction steel, the application of steel pipes is becoming more and more common, and the demand is also steadily increasing. Steel pipes refer to round steel with a larger diameter and longer length. In the production process of steel pipes, a series of steps such as straightening and cutting are required;

[0003] The main purpose of steel pipe straightening is to improve the quality and use effect, which is mainly manifested in the following aspects: improving mechanical properties, improving accuracy and surface quality, and improving workability. This requires the use of a steel pipe straightening device. The steel pipe straightening devices in the prior art generally use two rows of upper and lower pressure rollers for straightening. Both the upper and lower rows of pressure rollers are funnel-shaped, and rely on the middle extrusion surface for extrusion and straightening. When straightening steel pipes, they are generally products after cooling and shaping, with a certain recovery toughness, resulting in poor straightening effect. And the existing steel pipe straightening devices lack an effective preheating function. Therefore, the utility model proposes a straightening device for steel pipe processing to solve the problems existing in the prior art. Content of the Utility Model

[0032] The straightening device for steel pipe processing presses down and approaches the base 1 through the top seat 2, so that the pressure rollers 6 on the first rotating seat 3 and the second rotating seat 4 approach each other to squeeze the steel pipe for straightening. For steel pipes with strong toughness, the first worm 11 rotates to drive the first worm gear 8 to rotate, so that the rotating arm 9 rotates, bringing the burner nozzle 10 close to the steel pipe. The burner nozzle 10 is connected to the air supply part to spray out burning flames, so as to preheat the steel pipe before each straightening stage, facilitating straightening and shaping.
