Guardrail Roll Forming Machine rolling stability and service life
Mar 31, 2018

The principle of the average force of each pass in the Guardrail Roll Forming Machine, the average force of the entire roller, The wear and tear of the entire equipment is balanced, so that the service life of the rollers can be extended to a certain extent. The use of C12MoV material for the rolls is to use their wear resistance. However, the specific strength and hardness are contradictory, and the red hardness of C12MoV should be used for heat treatment. After quenching, the hardness can be reached twice or even three times.

The circular arc portion of the Guardrail Roll Forming Machine is the core part of the slide rail, and the first few roads will be effectively shaped after the arc, When folding the standing edge in the next pass, it should be effective to protect the already formed arc through the upper and lower rollers or the horizontal wheel for effective tube bundle protection.

Guardrail Roll Forming Machine rolling stability issues, often encountered in the production of material in the raceway in the left and right side of the problem,

In fact, it is the reason for the asymmetrical force of a single set of rollers. On the left side, the force is large and the material is swinging to the right; the right side is strongly stressed, and the material is swinging to the left.

The non-deformation area of the Guardrail Roll Forming Machine should be as far as possible without pressure (such as the bottom of the slide rail). During the assembly, the gaps between the upper and lower roller sections should be the same. Before the material is bitten in, the guide ramp should be set according to the rolling state of the front lane. Before the steady pressure, the material slides smoothly in the roll.

The problem of bending distortion in the manufacture of Guardrail Roll Forming Machine is mainly caused by unbalanced forces. Left and right force imbalance, left and right bending, unbalanced upper and lower forces, resulting in distortion.

Solution: Balanced force design, accurate processing, easy installation and adjustment.
