Background

Generally, metal materials such as metal bars, wires, pipes, etc., which are commonly used for, for example, cold air transportation of cooling/heating media, fluids, etc., are usually wound into coils for easy transportation and storage to facilitate stacking and reduction of the overall size of the storage, and then cut into appropriate sizes when in use. Since the metal bar, wire rod, and pipe line are bent and deformed during winding and storage, the metal bar, wire rod, and pipe line must be straightened by the straightening mechanism.
