It can improve the plate shape of the product, make its performance uniform, and ultimately achieve the purpose of improving product quality. The full name of the stretching straightening machine is the stretching bending straightening machine. The principle is to achieve the straightening effect by repeatedly bending the plate and strip.

[0004] The straightening machine is generally cooled by circulating water. The existing circulating water cooling equipment generally receives the circulating water through a container, absorbs the heat of the circulating water through the heat sink and then discharges it. Since the high-temperature circulating water continuously enters the container, the high-temperature circulating water will affect the inside of the container. This method will lead to a decrease in cooling efficiency. In addition, the existing circulating water cooling equipment uses a fan to cool the heat sink. This method will cause the temperature of the airflow to rise after contacting the heat sink, resulting in a decrease in heat transfer efficiency when the airflow contacts other heat sinks, affecting the cooling efficiency.
