How Straightening Machine Works?
 

 

A straightening machine works by leveraging hydraulic force to effectively straighten a wide range of metal materials, ranging from rods, bars, and tubes, to wires. The process involves clamping the metal material securely in place between two opposing rollers. Then, they put pressure on the material until it is bent in the opposite direction of the original bend, thus straightening it. The hydraulic force can be adjusted based on the thickness and hardness of the metal material to ensure accurate and efficient straightening.


The straightening machine is equipped with advanced sensors that provide real-time feedback during the straightening process, ensuring that the metal material is properly aligned throughout the process. Additionally, the machine is designed to be highly versatile, with the ability to straighten metal materials with varying diameters, lengths, and thicknesses.


Furthermore, HOREN's straightening machine leverages multiple rollers to provide various arrangements reducing any potential damage on the surface during the straightening process. This results in a high-quality finish that meets the stringent requirements of various industries, such as construction, automotive, and aerospace.


In summary, HOREN's straightening machine is a highly efficient and versatile piece of equipment that leverages mechanical force and easy-to-use position gauges on each roller to straighten metal materials with incredible accuracy and precision. With its reliable assembly, the machine ensures that the finished product is of the highest quality, meeting the demands of various industries irrespective of their requirements. 

Different Straightening Machine Techniques
 

 

Rotary tube straightening machines get their name from the tube that rotates while passing through the machine. The rolls hold and rotate the tube while feeding it through the machine. This is carried out until the entire or the desire length of the tube has been straightened. When the tube passes through the machine, it is exposed to two straightening forces, namely, bend (or offset) straightening, and pressure straightening.

 

Bend Straightening
One or more pairs of rolls can be adjusted to cause the tube to follow a curved path through the machine. Bending the tube in this manner is the main straightening action.

 

Pressure Straightening
Each pair of rolls can be adjusted so that the gap between them is slightly smaller than the outside diameter of the tube. As the tube passes through this limited gap, it is exposed to pressure. If this pressure is sufficient, then it causes the tube walls to be strained past their elastic limit, thereby causing some straightening of the tube. If the ability to squeeze the tube is used properly, it will help the tube to “round up”, thus removing some or all of its ovality.

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.
3. Adjust 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.

The Operating Steps Of The Straightening Machine
 

 

1. Before starting up, check if the hydraulic oil in the hydraulic station, gearbox, and gear oil in the transmission box are fully stored.

 

2. Before starting the main motor, perform angle inspection and adjustment, as well as adjust the working pressure of the hydraulic system.


3. Inject lubricating oil into each lubrication point and check the operation status of the mechanical transmission part to ensure flexible operation and installation.


4. Operators should wear personal protective equipment and are not allowed to leave or cross work after starting up. After the oil temperature and oil pressure at the hydraulic station reach stability, lift the upper straightening roller to its initial position.


6. Manual feeding, feeding the steel pipe through the third pair of straightening rollers, and then pressing and clamping the upper straightening roller.


7. Start the main motor, and the steel pipe rotates forward while being straightened.


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


9. If reverse straightening is required, the host can be reversed by using the reverse knob on the control panel to perform reverse straightening.
