摘要
目的研究不同波长对板料锤击式渐进成形性能的影响规律。方法以波长为单一因素,将波长值从0.5~5 mm进行多次重复性实验,分别与普通渐进成形实验结果进行对比。结果波长对材料的成形性有显著影响,锤击式渐进成形波长值在0.5~5 mm时,板料的成形性能均高于普通渐进成形,随着波长的增加,板料的成形性能降低,成形时间减少。结论锤击式渐进成形相对于普通渐进成形在成形性能方面具有优越性,综合考虑成形性能、加工时间和表面质量等因素,板料锤击式渐进成形波长为0.5 mm时,成形性能最好。
The paper aims to study effects of different wavelength on the incremental forming process of sheet metal. With the wavelength as a single factor, the wavelength tested was repeated from 0.5-5 mm to be compared with experimental results of ordinary incremental forming. The wavelength had significant effects on the formability of material. When the wavelength of the hammer type incremental forming was 0.5-5 ram, the forming performance of sheet metal was higher than ordinary incre- mental forming; with the increase of the wavelength, the formability was reduced, and the forming time was also reduced. The hammer type compared to ordinary incremental forming has superiority in forming performance of incremental forming. Consi- dering the forming performance, machining time and surface quality, the forming performance is the best when the wavelength of the hammer tvoe incremental forming of sheet metal is 0.5 man.
