Abstract:

 For the problems of incomplete filling and easily detached marks for air conditioning freezing valve in the practical production due to the complex shape, firstly, based on finite element analysis software Deform-3D, the finite element simulation of the original forming scheme of air conditioning freezing valve was conducted, and it was found that poor local forging processability and insufficient metal fluidity of valve body were the main causes of the forming defects. Secondly, the original forming scheme was optimized by deepening the middle valve hole, changing the local characteristics of handle, and reducing the diameter of blank to make the metal flow and deformation more fully. Finally, the optimizated scheme was experimentally verified by a multi-directional die forging hydraulic press, and the experimental results were completely consistent with the finite element simulation results, solving the questions such as incomplete filling at the end of valve handle and easily detached marks. The results show that the valve body formed by the optimized forming scheme has a complete appearance, smooth surface, and no flash or overflow, and has complete and clear characters and marks on the surface of valve body with a firm connection. The maximum forming force is reduced by 17.5%, the material utilization rate is increased by 7.2%, and the economic benefit is remarkable.
