摘要

摘要: 解决了板材数控渐进成形的厚度减薄严重、加工时间长等缺陷,分析了数控渐进成形和拉形的主要特点,研究了基于数控渐进成形机床伺服托架的拉形辅助的数控渐进成形技术。设计了专用夹具在数控渐进成形机床上实现了一次装夹的混合成形。通过试验分析了两种成形方法对产品厚度及成形时间的影响,结果表明,此混合成形与单一的渐进成形相比,可以有效的减少零件的过度变薄及加工时间,可以突破渐进成形的成形极限角,成形出单一的渐进成形不容易成形的零件。

Abstract: Analyzing the main features of the NC incremental forming and stretch forming, we investigate a hybrid of NC incremental forming with stretch forming based on the servo control system of NC incremental forming equipment so as to solve the heavy thinning and long time of the NC incremental forming. A new special fixture was developed to realize the hybrid forming on the original incremental forming equipment with one clamping system. The influences of the two methods on the thickness and forming time are analyzed. The results show that comparing with the normal incremental forming this hybrid forming technology can reduce the thinning and forming time series and form the parts that the normal incremental forming technology cannot form by breaking the forming limit angle of incremental forming.
