Cold Roll Forming

Cold forming is a new technology and new technology for metal sheet forming, material saving, energy saving, and high efficiency. By using this process, not only can high-quality steel products be produced, but also the cycle of product development can be shortened and production efficiency can be improved, thereby improving the market competitiveness of enterprises.


In recent years, cold-formed steel products have been widely used as important structural parts in many fields such as construction, automobile manufacturing, shipbuilding, electronics industry, and machinery manufacturing. Its products range from ordinary rails, doors and windows and other structural parts to special profiles made for special purposes. Cold-formed steel has better cross-sectional performance per unit weight than hot-rolled steel products and has a high surface finish and dimensional accuracy. Therefore, cold-formed steel can achieve the dual effect of saving steel and saving energy instead of hot-rolled steel.


The development of curved steel has been highly valued. It is the user's constant desire for the variety, specifications, and quality of cold-formed steel products, which has led to the rapid development of cold-bending forming technology.


On cold roll forming lines the stands are fixed on the machine basement, and if you need to replace the roll forming tooling, it is necessary to manually take down the rollers from the shafts.


If the profile change only involves a size change of the section (for example a width change), the rollers can be modified by re-positioning the C shape spacers without taking the rollers down.

The core part of the cold forming machine - the roll. It is the soul of cold forming, the design of the roll is extremely important, and the design features of the roll are as follows:


1. The average force principle of each pass of the cold-bending forming machine, the average roller of the whole line is subjected to the average force, the wear is balanced, and the service life of the roll is prolonged.


2. The material of the cold roll forming machine adopts its wear resistance, but the specific strength and hardness are contradictory. The red hardness of C12MoV should be utilized during heat treatment, and the hardness can be achieved after two or even three times of tempering after quenching.
