超声振动单点增量成形力研究
Research on Forming Force in Single Point Incremental Forming with Ultrasonic Vibration
摘要
Abstract
In the single point incremental forming process,the different process conditions and forming force will largely change the contact stress and strain state,sheet rupture,accumulation and wrinkling defects,finally inducing the lower forming quality and precision.An ultrasonic vibration single point incremental forming method was proposed in this paper based on the numerical control technology.This method will give rise to a lower force and a higher quality by changing the momentary contact state,lubrication condition and defromation mechanism between the tool head and the workpiece.The ultrasonic vibration spindle and sheet clamping system were designed based on the experiment platform of Hass numerical control machine and the test forming force system of Kistler was also designed.Through a large number of experiments,the forming force variation regularities under different vibration process were obtained.关键词
