[0002] Air conditioning valve blades are an important component in air conditioning systems, usually used to adjust the flow of coolant to control the cooling or heating effect of the air conditioning system. They are usually made of metal or plastic and have a specific shape and structure to ensure that the fluid can flow in the expected way and achieve the required temperature control. Many materials used in air conditioning valve blades, such as metal materials (such as aluminum alloy, steel) or plastic materials, need to be bent during processing. The use of cold bending forming devices can complete the forming while maintaining the original properties of the material, avoiding problems such as material softening and oxidation that may occur during hot processing. The cold bending forming device can perform precise forming according to the pre-designed mold to ensure that the shape, size and angle of the air conditioning valve blades meet the requirements.
