Steel pipe straightening machine straightening process and operation steps
- Mar 20, 2018 -

Steel pipe straightening machine is a special equipment for straightening various steel pipes and other materials. Steel pipe straightener is mainly used to straighten the steel pipe by straightening roller to change its straightness. There are usually two rows of straightening rolls, with varying amounts. There are also two-roll straightening machines, which rely on the change of the angle of the two rollers (intermediate concave, hyperbolic roller) to straighten different diameter materials.


First, on the straightening process of the steel pipe straightening machine is introduced:


In the process of operating the steel pipe straightening machine, the position of the roller and the direction of movement between the straightened pipes constitute a certain angle, and two or three large ones are the active pressure rollers, which are rotated by the motor in the same direction. The other small roller on the other side is a driven pressure roller that is rotated by the rotating pipe friction force. In the straightening process, these small rollers can be adjusted forward or backward simultaneously or separately. Generally, the more rollers, the higher the precision of the products after straightening.


Second, on the main operation steps of the pipe straightener:


1. Before opening the steel pipe straightening machine equipment, the inspection work required by the staff mainly includes checking whether the hydraulic oil of the hydraulic station, the gear box, and the gear box are full of gear oil. In addition, before starting the main motor, check the adjustment of the angle of rotation and the working pressure adjustment of the hydraulic system.


2. When the inspection and confirmation are good, the main motor is turned on, and the steel pipe is rotated forward while being straightened by the pipe straightening machine. When the motor stops, the straightening roller stops straightening, the upper leveling roller lifts, and the straightened steel pipe is sent out. After shutting down the pipe straightener, the main power supply should be cut off.
