The principle of the straightening machine: to withstand the curved part of the steel to considerable back bending or elongation, so that the part produces a certain elastic-plastic deformation. When the external force is removed, the steel experiences elastic recovery and then becomes straight.

What is the straightening machine for?

Straightening machine is a device for straightening metal profiles, rods, pipes, wires, etc. The straightening machine uses straightening rollers to round bars, etc. Squeeze to change the straightness. As a rule, there are two rows of straightening rollers, the number of which varies. There are also two-roller straightening machines that depend on the angular change of the two rollers (concave in the middle, hyperbolic roller) to straighten materials with different diameters. The main types are pressure straightening machine, balancing roller straightening machine, shoe roller straightening machine, rotating counter bending straightening machine.

What is the working principle of the straightening machine?

1.Before starting the machine, check that the hydraulic oil in the hydraulic station, the transmission oil in the reduction transmission and the transmission are full.

2.Before starting the main motor, check and adjust the rotation angle and adjust the working pressure of the hydraulic system.

⒊Inject lubricating oil into each lubrication point and check the operating state of the mechanical transmission part to make transportation flexible.

⒋Operators should wear protective clothing and must not leave their posts or shift posts after starting the machine.

5.After the oil temperature and oil pressure of the hydraulic station are stable, the upper straightening roller is raised to the starting position.

⒍Manual reception, the steel tube is sent through the third pair of straightening rollers, and then the upper straightening roller is pressed down and clamped.

⒎Start the main engine, the steel tube rotates forward, straightening it.

8.The motor stops, the straightening roller stops straightening, the upper straightening roller lifts, and the straightened steel tube is sent out.

⒐If reverse straightening is required, the main machine can be directed backwards using the reverse rotary knob on the console to perform reverse straightening.

⒑The main motor stops, the straightening roller stops straightening, the steel pipe is returned to the starting position and the next command of the straightening program is repeated.

⒒ Turn off the main power supply after shutdown and do not change the program controller as desired.

What precautions should be taken for the operation of the straightening machine?

1. Pay close attention to the straightness of the steel pipe. When first setting, make sure that the steel tube touches three quarters of the straightening roller body and ensure that the gap is not greater than 0.1mm.

2.The straightening speed should be adjusted appropriately according to the degree of bending of the steel pipe and the material of the steel pipe to be straightened.

⒊Adjust the distance between the upper and lower roller according to the material, curvature and required accuracy of the steel pipe to ensure the directional reduction.

4.During the straightening process, it is strictly forbidden to touch the straightening roller and the moving steel pipe with your hands, and pay attention to the surface quality of the steel pipe to avoid scratches and indentations on the steel pipe surface.
