摘要

研究了一种弧形结构钛合金铸件蜡模的变形规律

分析了蜡模冷却方法、工装校形时间、车间存放时间对蜡模尺寸变形的影响。结果表明

弧形结构件蜡模冷却过程中弧面会发生翘起变形

水冷比空冷的蜡模变形严重。制作蜡模专用工装可控制蜡模变形

工装校形时间不同

蜡模尺寸控制结果不同

校形3h后蜡模尺寸稳定。蜡模完成校形后

自由放置继续变形

放置1天蜡模变形最大为0.26mm

放置1天后变形幅度趋小

放置3天后尺寸保持稳定。

Abstract

The wax deformation of titanium alloy casting with arc structure was investigated

and the effects of the wax cooling method

dimensional calibration time and storage time on the wax dimension were analyzed.The results reveal that the cambered surface is warping deformed during cooling

and the deformation of wax cooled in water is more severe than that in air.The wax deformation can be controlled by appropriative wax pattern

and dimension is affected by the calibration time

which becomes stable after deformation for 3 h.The wax pattern is placed freely and continue to deform after calibration.The deformation reaches the maximum value after 1 day

the minimum value after 2 days and the dimension becomes stable after 3 days.
