1. Whether there is a certain relationship between the cold bending of cold-formed steel machinery and the 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 in a cold state by means of mechanical force. The hot bending is to bend the pipe at a specified temperature, and it is generally at the yield point temperature of the pipe.
2. How should the cold-formed steel machinery be debugged? In addition, what should be paid attention to in the cold bending of steel bars?
The commissioning of cold-formed steel machinery, specifically speaking, should be carried out according to personal operating experience, and there is no clear regulation. For cold bending of steel bars, if cold-formed steel machinery is used, then there are some precautions. For example, we should pay attention to the cold bending performance of steel bars. If its performance is not good, then it is prone to problems such as brittle fracture.
3. For the mechanical cold bending of pipes, if cold-formed steel machinery is used, then, should we pay attention to the problem of plasticity?
For the mechanical cold bending of the pipe, if the cold-formed steel machine is used, then it is necessary to pay attention to its plasticity. In addition, pay attention to the specific aspect of the reverse bending amount, because if it is not handled well, it will produce an ellipse. This phenomenon is problematic. Moreover, the better the plasticity, the smaller the tensile coefficient can be.
