Straightening machine is straightening equipment for metal profiles, bars, pipes, wires, etc. Straightening roller straightening machine by pressing rod can change straightness. Usually there are two rows of straightening rollers in different numbers. There are also two kinds of roll straighteners, which depend on the change of two roll angles (middle concave hyperboloid rolls) in straightening with different diameters. There are pressure straightener, balance roll straightener, shoe roll straightener, rotary anti-straightener and so on.


Principle on Straightening Machine
Roller position straightens product at one angle with moving direction. Two or three large active pressure rollers are driven by one motor and rotated in the same direction. On the other side, some small rollers drive the pressure rollers. It depends on the rotating rod or tube to rotate through friction. In order to achieve the required roll products, these small rollers can adjust the forward or backward positions simultaneously or separately. The more rolls, the higher the accuracy of straightening products. After rolling and biting, we continue to do linear or rotational motion, so that all aspects of the product can withstand compression, bending, flattening and other deformation, and ultimately achieve the purpose of straightening.


Practice of Straightener
Before starting, check whether the hydraulic oil, gearbox and gear oil of the hydraulic station are filled.
Before starting the main motor, check and adjust the angle to adjust the pressure of the hydraulic system.
_The lubricant is injected into the lubrication point to check the running state of the mechanical transmission parts and make it a flexible transportation tool.
Operators should wear PPE through boots and chord holes.
After oil, the hydraulic oil is stable and the straightening roll rises to the initial position.
_The third clamping pressure is fed through the manual feeding and the straightening roll of the steel tube straightening roll.
Start the main motor, and the steel plate rotates forward during straightening.
_Motor stop, stop straightening straightening roll, straightening roll lifting, straightening feeding pipe.
_The stage knob can be reversed and rectified by operation, so that the main engine can be reversed and straightened reversely.
The main motor stops, the straightening roll is stopped and the straightening pipe is returned to the starting position, and the straightening process is repeated until the next program instruction is straightened.
_After closing, the main power supply can not be changed.
