Description
Technical Field

Therefore, how to provide an electrically driven connecting rod type bending machine which can solve the problem of environmental pollution caused by periodic replacement of hydraulic oil by a traditional hydraulic bending machine and solve the problem of energy conservation and non-ideal caused by large load inertia of a synchronous wheel by the traditional servo bending machine is a problem to be solved by a person skilled in the art.
