What is the function of the straightening machine support roller?

The supporting rollers of the straightening machine play a crucial role in the straightening process, mainly including the following aspects:

Provide support and load-bearing capacity

Supporting the straightened material: During the operation of the straightening machine, the Support Roller provides a stable support point for the straightened material (such as steel, pipe, etc.). Taking steel straightening as an example, whether it is large H-beams or small wire rods, the support rollers can ensure that the steel is always in the correct position during the straightening operation by the straightening roller of the straightening machine, preventing it from falling or deviating due to gravity or straightening force, and ensuring the smooth progress of the straightening process.

Carrying straightening pressure: During the straightening process, the Straightening Roller will apply a certain amount of pressure to the material to cause plastic deformation, thereby achieving the purpose of straightening. The support roller needs to cooperate with the straightening roller to jointly bear and disperse these pressures. For large-sized and high-strength materials, the required straightening pressure is very high, and the support rollers must have sufficient strength and stiffness to withstand these pressures, ensuring the stability of the overall structure of the straightening machine and avoiding equipment damage or poor straightening effect due to the inability of the support rollers to withstand pressure.

Improve straightening effect

Cooperate with straightening rollers to apply pressure: The support rollers and straightening rollers work together to more accurately control the pressure distribution applied to the material. By adjusting the position and pressure of the support rollers and straightening rollers reasonably, the straightened material can be subjected to uniform force in various parts, thereby better eliminating internal stress and deformation of the material, improving straightening accuracy, and achieving higher requirements for straightness and flatness of the material.

Reduce material surface damage: High quality support rollers can ensure straightening effect while reducing damage to the surface of the straightened material. Support rollers are usually made of suitable materials and surface treatment processes, with good wear resistance and smoothness. When in contact with the material, they can drive the material forward with minimal friction, avoiding defects such as scratches and indentations on the surface of the material and maintaining its surface quality.

Auxiliary guidance and positioning

Guiding material forward: The support roller can guide the straightened material to advance along a predetermined path and direction. In pipe straightening, the support rollers can ensure that the pipe enters and passes through the straightening machine in a straight direction, preventing the pipe from deviating or twisting during the straightening process, allowing the pipe to accurately pass through each straightening roller, ensuring the accuracy and quality of straightening.

Determining the position of the material: It can accurately determine the position of the straightened material, so that it maintains the correct relative position relationship with the straightening roller. When straightening the board, the support roller can position the board at the appropriate height and angle, ensuring that the straightening roller can evenly act on the surface of the board, effectively straightening the board, and avoiding situations of excessive or insufficient local straightening.
