The cold bending equipment industry is now developing well, which has greatly increased the competition between enterprises. The direct consequences of competition are two-fold: firstly, it promotes the development of the industry, and secondly, it accelerates the pace of backward companies leaving the market, providing convenient conditions for the resource reorganization of the industry.
The products produced by cold roll forming machine have high smoothness, exquisite appearance, and precise size. The steel produced by the cold roll forming machine belongs to the economic section steel, which saves costs. The cold roll forming machine is widely used to replace hot-rolled profiles and other varieties of cold-bending steel.
The composition of the cold roll forming machine: The cold roll forming machine is mainly composed of a base, mechanical transmission, cold bending operation system, hydraulic work system and other parts.
The working principle of the cold roll forming machine: When the cold roll forming machine is working, the steel plate or other metal materials that need to be cold-bent are placed between two active wheels. The hydraulic system is started, and the hydraulic cylinder pushes the dovetail groove and the cold-bending wheel to cold-press the steel. When the required curvature is reached, the hydraulic system is closed, and the product is completed.
Cold roll forming machine is a type of profile processing equipment used in tunnels, subways, underground passages and other places. Compared with press equipment, cold roll forming machines have the advantages of stable performance, high work efficiency, and good quality of produced profiles. However, sometimes the cold roll forming machine may have some defects due to operational problems, and one of the common problems is the deformation of the product during processing.
So, how should we deal with the problem of profile deformation in the production of cold roll forming machines? Firstly, we need to analyze the reasons for the problem. Generally, the common reason for profile deformation is that the force is unbalanced, which may be caused by improper operation or improper placement.
Therefore, to solve the problem of profile deformation in the cold roll forming machine during processing, reasonable deformation allocation should be made during design, especially when producing the last few processes, the deformation should not be too large. Secondly, side rollers and bend rollers can be used to pre-bend the profiles, which can effectively prevent the profiles from swinging arbitrarily during the processing. Finally, if profile deformation still occurs during the production process, the roll allocation should be adjusted according to the actual situation.
