The cold roll forming machine is a metal cold roll forming equipment commonly used in industrial production, which can meet the requirements of specific shapes in industrial production. Once the cold roll forming machine is available, it has achieved a good market development, and currently varieties on the market. Many, for some hot-rolling methods, it is difficult to produce a variety of profiles with uniform wall thickness and complex cross-section shape, and it can easily handle cold-formed steel of various materials.
The cold roll forming machine produces a finished product with high finish, beautiful appearance and precise dimensions. The steel produced by the forming machine is an economical section high-efficiency steel, which saves costs. The cold roll forming machine is widely used to replace hot-rolled steel profiles and other varieties with cold-formed steel.
The composition of the cold roll forming machine: The cold forming machine is mainly composed of a base, a mechanical transmission, a operating system, a hydraulic working system and others.
The cold forming machine works: When the cold forming machine is working, metal materials such as steel plates that need to be processed by cold forming technology are placed between the two driving wheels, and the hydraulic system is started to make the hydraulic cylinder push the dovetail groove and the cold forming wheel cold-pressed steel when the design is reached. Turn off the hydraulic system when needed in the arc and start.
Cold bending equipment is a profile processing equipment used in tunnels, subways, underground passages, etc. Compared with press equipment, it has the characteristics of more stable performance, higher work efficiency and better quality of produced profiles. However, sometimes the cold bending equipment may have some defects in the operation process due to operational problems, the most common of which is the problem of product processing deformation.
So, what about the problem of cold bending equipment encountering deformation of the profile during processing? First, we need to analyze the cause of the problem, and the most common cause of profile deformation is caused by the imbalance of force, which may be caused by improper operation or due to improper placement.
Therefore, to solve the problem of cold deformation of the cold bending equipment encountered in the processing, first of all, in the design, there must be a reasonable distribution of deformation, especially in the last few production of cold bending equipment, the deformation can not be too large. Secondly, the profile can be pre-bent using side rolls and over-bending rolls, which effectively prevents the profile from arbitrarily oscillating during processing. Finally, if there is still a problem of profile deformation during the production process, then the distribution of the rolls should be adjusted according to the actual situation.
