Description
Technical Field
The utility model relates to the field of steel pipes, in particular to steel pipe straightening equipment.
Background
The straightening of the steel pipe is an important link in the production of straight-seam steel pipes, in particular to a sleeve pipe with API standard and a special pipe for mechanical equipment. These steel pipes have not only strict requirements on the steel grade and the welding quality, but also high requirements on the flatness of the steel pipes. Because the deviation in flatness is directly related to the machining and connection of the pipe end threads and the pipe collar, and the deformation of the pipe during use, there are two machining methods for pipe rotation and tool rotation
For straightening of steel pipes, it is not easy to remove the steel pipes from the bends, and the reasons for bending the steel pipes are many. Such as thermal effects of the weld, eccentricity of the formation, imbalance in compressive and bending forces, but basically bending is the effect of stresses in the steel pipe.
The straightening machine is used for straightening a pipeline through multiple elastic plastic bending deformation, and two basic methods are used for straightening the steel pipe: linear straightening and rotational straightening. Both methods are essentially straightened, according to the principle of removing internal stresses, but they have a great use and straightening effect.
The tube to be straightened is fed from the paper feed device at the end of the machine into the lower roll of the straightener and then pressed under the upper roll to stop it in the corresponding position. The upper and lower roller systems are inclined at an angle relative to the axis of the straight tube. The hyperbolic generatrix of the rollers coincides with the outer diameter of the tube and is wrapped, the three upper rollers are pressed against the tube by their respective hydraulic cylinders, and the two lower rollers are driven and rotated by their respective motors, driving the tube in rotation and movement along the axis. The rotation direction and axial movement of the pipe can be changed by changing the rotation direction of the motor to achieve reversible straightening, and then the straight pipe is sent to the material rack through the discharging device at the other end. For the pipeline with larger local bending deformation, the punches at the two ends can be used for local straightening and then overall straightening is carried out.
At present, after the steel tube straightening is finished, the situation of the steel tube straightening can only be judged through an operator, the experience of the operator is very depended, the steel tube straightening detection efficiency is extremely low, and when the steel tube straightening is finished, automatic blanking cannot be realized on steel tubes of different sizes generally, the blanking carrying process is carried, the straight line type of the steel tube just finished by straightening is influenced, the steel tube loss is caused, the steel tube straightening device aims at carrying out omnibearing scanning on the steel tube finished by straightening, the situation of the steel tube straightening is recorded in real time, the steel tube is clamped in the straightening process, shaking is avoided when the steel tube is straightened, automatic blanking is carried out on the steel tube finished by straightening, and the steel tube straightening efficiency is improved.
