Design and Optimization of Ultrasonic Assisted Drilling Luffing Rod
In order to increase the quality and efficiency of thread forming,this paper adopts the double mobile rolling process,takes HRB500 rebar rolling process as the research object,uses DEFORM software to simulate,and studies the tan-gential velocity,radial feed velocity and friction coefficient of the rolling plate in the process of wire rolling.The final results show that the tangential velocity is an important parameter of thread forming and machining efficiency,and the radial veloci-ty can be selected in a suitable range according to the equipment.By comparison,it is determined that HRB500 rebar by double mobile rolling wire forming parameters are tangential speed 200mm/s,radial speed 0.7mm/s or 1.6mm/s,friction coefficient 0.7.The conclusion can provide reference for the selection of the process parameters of HRB500 rebar double travel wire rolling.
