Description

TECHNICAL FIELD

[0001] The utility model relates to steel pipe production technical field, specifically, and relates to a straightening machine for steel pipe production. BACKGROUND

[0002] Steel pipe is prone to bending in the application process, and needs to be straightened by a straightening machine for surface flatness after forming. The existing steel pipe straightening machine needs to be straightened by multiple straightening wheels, and the straightness of the multiple straightening wheels directly determines the straightening effect of the steel pipe. The angle and flatness of the straightening wheels need to be adjusted during the straightening process, which has too many operation steps, limited application range, and is not conducive to promotion.

[0003] For example, the straightening machine for steel pipe production disclosed in Chinese Patent No. CN212419183U places the bottom of the steel pipe inside the lower steel pipe sleeve, with the curved part of the steel pipe arranged left and right. Then, the switch of the air cylinder is pressed to move the output shaft of the air cylinder downward. At this time, the upper steel pipe sleeve moves downward under the action of the output shaft of the air cylinder, and the upper steel pipe sleeve and the steel pipe are clamped together. This arrangement is to facilitate the replacement of the steel pipe to be straightened. Then, the switch of the driving motor is pressed to rotate the driving shaft. Since the driving shaft and the driven shaft are connected through the first gear and the second gear, the driving shaft and the driven shaft will move together, and the two action rods will be rotated. When the two action rods rotate, the two action rods move to the opposite side of the two sliding plates, and the two sliding plates will move to the side of the steel pipe until they are in contact with the side of the steel pipe. In this way, the curved part of the steel pipe is straightened continuously. The diameter of the steel pipe only needs to be compatible with the inner circle of the upper and lower steel pipe sleeves. The distance and flatness between the straightening wheels do not need to be adjusted during the straightening process, reducing the steps of straightening the steel pipe and improving the efficiency of straightening the steel pipe. The straightening effect on the steel pipe is good.

[0004] However, the straightening machine for steel pipe production in the above-mentioned application has limitations because the surface of the steel pipe may have rust or adhered debris that needs to be cleaned before use when straightening the steel pipe.

[0005] Therefore, a straightening machine for steel pipe production is proposed. Utility model content
