1. Is there a certain relationship between cold bending of cold-formed steel machinery and hot bending?
Cold bending in cold-formed steel machinery has nothing to do with hot bending, and there is a big difference, because cold bending is to bend the pipe fittings in a cold state by means of mechanical force. Hot bending is to bend the pipe at a specified temperature, and generally at the yield point temperature of the pipe.
2. How should cold-formed steel machinery be debugged? In addition, what should be paid attention to in the cold bending of steel bars?
The debugging of cold-formed steel machinery, specifically speaking, should be carried out according to personal operating experience, and there is no clear regulation. As for the cold bending of steel bars, if cold-formed steel machinery is used, then there are some precautions. For example, attention should be paid to the cold-bending performance of steel bars. If the performance is not good, then it is prone to problems such as brittle fracture.
3. For mechanical cold bending of pipes, if cold-formed steel machinery is used, should we pay attention to the problem of plasticity?
For the mechanical cold bending of pipes, if cold-formed steel machinery is used, then attention should be paid to its plasticity. In addition, attention should also be paid to the specific aspect of the amount of reverse bending, because if it is not handled properly, it will produce ellipse This phenomenon is problematic. Moreover, the better the plasticity, the smaller the tensile coefficient can be.
