Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe manufacturing, in particular to high-precision aluminum pipe profile straightening equipment. Background Art

[0002] Steel pipe straightening equipment is a kind of mechanical equipment specially used to repair and improve the straightness of steel pipes. It is widely used in steel, construction, oil, gas, machinery manufacturing and other industries. These equipment can effectively correct the bending deformation of steel pipes caused by production, transportation, storage or use, and ensure the dimensional accuracy and performance of steel pipes. The following are some key components and working principles of steel pipe straightening equipment: Key components: 1. Feeding system: responsible for feeding the steel pipes to be straightened into the straightening machine. Some equipment is equipped with automatic feeding device to improve work efficiency. 2. Straightening unit: the core part, composed of a series of parallel straightening rollers, which can adjust the spacing and pressure according to the diameter and bending degree of the steel pipe. The rollers are divided into upper and lower rows, and the steel pipe is squeezed by applying vertical pressure to gradually restore it to a straight shape. 3. Drive system: Provide power for the straightening rollers to ensure that the rollers can continue to rotate and apply the necessary correction force. The drive system can be electric, hydraulic or pneumatic. 4. Control system: Modern straightening equipment is usually equipped with advanced electronic control systems to adjust parameters such as straightening speed, pressure, roller spacing, etc. to adapt to steel pipes of different specifications and deformation degrees. 5. Discharging system: The straightened steel pipe is output through the discharging system. Some equipment will also be equipped with detection devices to conduct immediate inspection of the straightening effect. Working principle: Progressive straightening: The steel pipe passes through a set of opposing straightening rollers in turn. Each time it passes through a pair of rollers, the bending part will be subjected to a straightening force. As the steel pipe gradually passes through all the roller groups, the bending is gradually eliminated until the predetermined straightness standard is reached. Pressure adjustment: According to the material, diameter, wall thickness and bending degree of the steel pipe, the pressure and spacing of the rollers are adjusted to ensure that the deformation can be effectively corrected without damaging the steel pipe. Automatic or manual adjustment: Advanced equipment can automatically detect the bending of the steel pipe and adjust the straightening parameters accordingly, while simpler equipment may require manual adjustment. Cooling or heat treatment: During or after the straightening process, the steel pipe may be cooled or heat treated as needed to eliminate internal stress and prevent the straightened steel pipe from bending again. The design and function of steel pipe straightening equipment are constantly improving, aiming to improve the straightening accuracy, efficiency and automation level to meet the needs of different industries for high-quality steel pipes.

[0003] However, in the process of correcting the steel pipe inside the correction component of the prior art, two rows of correction wheels are generally rotated, and the pressure between the correction wheels is used to force the steel pipe to correct. This correction method is generally more effective for steel pipes with bends in the vertical direction, but the correction effect is not good for steel pipes bent in other directions. The prior art generally uses multiple sets of row-by-row correction wheels in different directions to improve this defect, but a large number of correction wheels greatly reduces the positioning accuracy of the device, while increasing the complexity of the machine, which is not conducive to subsequent maintenance.

This device specifically solves the technical problem of positioning difficulties caused by too many correction wheels in the prior art. At the same time, it has a compact structure and is very easy to operate and maintain. BRIEF DESCRIPTION OF THE DRAWINGS
