Numerical Simulation and Experimental Research on Roll Forming for Waveform Thread of Drill Rod
The advantages of roll forming process for drill rod were introduced.The FE software Deform-3D was used for the numerical simulation of roll forming process for waveform thread of drill rod,the stress-strain laws were acquired.Meanwhile,the effect factors of the roll forming were acquired by experiment.Finally,some defects in the experiment were analyzed,and the improvements were proposed.
