Description

Technical Field

[0001] This utility model relates to the field of steel pipe production technology, specifically to a device for controlling the uniformity of wall thickness in hot-rolled seamless steel pipes. Background Technology

[0002] With the acceleration of industrialization, steel pipes are widely used in various fields such as petroleum, chemical industry, and machinery manufacturing. In the production process of hot-rolled seamless steel pipes, inspection is usually only possible from one side, and the rotation of the pipe requires manual pushing. However, the friction between the pipe and the clamp is generally high, making rotation very time-consuming and labor-intensive. Furthermore, existing clamps generally cannot adjust the clamp opening according to the pipe size. Therefore, developing a wall thickness uniformity control device that can adjust the clamp opening size according to the pipe thickness and automatically rotate the pipe for thickness inspection has become an urgent need to improve the quality and inspection efficiency of hot-rolled seamless steel pipes.

[0019] Working principle: In use, the seamless steel pipe to be hot-rolled is first placed on the clamping device 3. The servo motor 303 is turned on to drive the central gear 304 to rotate, which in turn drives the spur gear 305 to rotate. The rotation amplitude of the spur gear 305 is determined according to the thickness of the steel pipe, thereby changing the opening size of the clamp 306 to accommodate steel pipes of different sizes. Then, the steel pipe can be hot-rolled manually using tools. After hot rolling is completed, the rotating device is turned on, and the stepper motor 701 drives the threaded rod 702 to rotate, thereby moving the threaded sleeve towards the steel pipe until the rotating wheel 707 presses against the steel pipe. The annular surface of the rotating wheel 707 is provided with a friction plate with extremely high friction. Then, the rotating motor 708 is turned on to drive the rotating wheel 707 to rotate. The rotation of the rotating wheel 707 drives the steel pipe to rotate. At the same time, the acoustic detector 10 is turned on to detect the thickness of various parts of the steel pipe, and the temperature detector 11 also detects the temperature of the steel pipe surface. After the detection is completed, the data is collected.
