Asphalt pump on the workpiece aging should be carried out before the process analysis Vibration aging effect depends on the choice of vibration aging process. Metallurgical butterfly body is made of cast structural parts, asphalt heat pump complex shape, relatively rigid, convex and concave surface and more, uneven wall thickness, large residual stress and complicated distribution. In the past, the process of using natural aging has many shortcomings. Since a company started using the VSR technology in 2005, great progress has been made in product quality and production efficiency. Years of production experience show that: Due to the complexity of the process of vibration aging, the box must be part of the vibration before the process analysis, design and optimization of vibration parameters to improve the effect of vibration aging. In accordance with the vibration failure of the process specifications, asphalt insulation pump on the workpiece aging process analysis should be carried out in order to achieve the purpose of saving power and working time. First of all, we should analyze the distribution of residual stress field, the requirements of dimensional accuracy, the working load and the possible causes of failure according to the material, structure and the manufacturing process and process of the blank, and then decide the implementation of vibration Aging process line and the key parts of aging.
