Our customer often say,how to select the best roll forming machine at affordable cost,but it is really a complicated question.Before your purchase of metal steel roll forming machine,there are several things to be considered.
Within the last few decades, due to the development of high-rise buildings, the steel-concrete composite floor system(composite steel floor decking) has been increasingly popular.Compared to the traditional reinforced concrete flooring system, there are many benefits that composite steel flooring decking system would bring.
China Iron and Steel Association (CISA) conducted a survey on eight industries that use a large amount of steel, and related to cold-formed steel in seven aspects: racking and shelf system,escalator guide rail,construction, machinery, automobiles, agricultural vehicles, shipbuilding, railways and containers. and Cold roll formed steel has a bright prospect in China.
Cold-formed steel is widely used due to its energy-saving and environment-friendly features, and the required load is no longer completely dependent on increasing the amount of sheet material or improving the mechanical properties of the material, but by changing the cross-sectional shape of steel p
One of the basic principles of the cold forming process is that the strip is bent in a straight line in the longitudinal direction. However, the pressure generated during bending deformation is combined with the residual stresses present in the strip, often the strip deviates from the cold-formed equipment.To solve this problem, a straightening mechanism should be used at the end of the cold roll forming machine.
Roll forming technology is widely used in different industries,which has greatly liberated the labour force and improved human’s productivity.Firstly,in construction and building industry,there are hollow elevator guide rail roll forming machines,door frame roll forming machine;in storage shelves and racking industry,,there are heavy duty and light duty racking cold roll forming lines.
With the Cold Roll Forming machine’s life increased, it will inevitably occur the aging wear and tear problems, which requires the maintenance of cold bending machine equipment to ensure the stability of its work, not to affect the normal production process.
Considering the escalator guide rail forming line working process,what matters should the escalator company need pay attention?
Elevator guide rail roll forming machine has also undergone tremendous changes, and gradually extended to the hollow elevator guide rail equipment, solid rails, escalators Rails and other products, more and more advanced production technology, the traditional manual production process is gradually being automated, CNC equipment replaced by the straightness of the guide, symmetry and surface roughness control means more and more advanced.
The roll forming process parameters play a major role in the quality of the final roll-formed product. Optimum configuration without any cost increase in the roll forming line could present accurate and flawless products. In this paper, a roll forming process experimental modelling of a symmetrical U-section profile from advanced high strength steel (AHSS) material (type DP600) is presented.
