瀝青 泵振動時效的效果取決于振動時效的工藝的選擇。冶金蝶閥體，是由鑄造而成的結構件，瀝青 泵形狀復雜，剛性相對大，凸凹面多，壁厚不均，殘余應力大且分布繁雜。以前采用自然時效的工藝中存在很多的缺點，某公司自2005年開始采用振動時效工藝以來，在產(chǎn)品的質量和生產(chǎn)效率方面取得了很大的進步。多年的生產(chǎn)實踐經(jīng)驗表明:由于振動時效的工藝比較復雜，必須對箱體類零件進行振前的工藝分析，設計優(yōu)化振動參數(shù)以提高振動時效的效果。按照振動失效的工藝規(guī)范，瀝青泵對工件時效前應進行工藝分析，以達到節(jié)約電能和工時間的目的。首先，應根據(jù)工件的材質、結構、毛坯制造的工藝形式和過程，分析箱體的殘余應力場的分布，尺寸精度要求，以及工作載荷，可能的失效原因等因素進行分析，然后再決定實施振動時效的工藝線及時效重點部位。
Whether the asphalt pump vibration aging on vibration aging process selection. Metallurgy valve body, is formed by the cast structural parts, the asphalt pump complex shape, rigidity is relatively large, the convex and concave surface, uneven wall thickness, residual stress distribution of large and complex. There are many shortcomings previously used in the natural aging process, a company since 2005 since the vibration aging technology, have made great progress in quality and production efficiency of products. Years of production experience has shown that: as the VSR process is more complex, must process analysis for vibration of the front of the box type parts, design optimization of vibration parameters to improve the effect of vibration aging. According to the process of standard vibration failure, the asphalt heat pump on the workpiece process analysis should be conducted before aging, in order to save energy and time. First of all, should be based on the process of form and process of workpiece materials, structure, blank manufacturing, analysis of the residual stress distribution, the precision requirement, and the work load, are other factors may cause failure analysis, and then make a decision process line of vibration aging and aging key parts.
