Analysis Of The Wear And Friction On The Surface Of Carbide Cemented Drawing Die For Copper Tube And Research On Service Life

In order to clear these causes of lots of drawing dies discarded. This paper researched the wear and friction of surface of carbide cemented YG6 drawing dies and the service life. Studied on the present workshop to experiment and recorded all kinds data about service dies. Results show that 74% outer die encounter wear, thickness of wear is from 0.01mm to 0.05mm. Float plug almost encounters no wearness. It explains why discardness of lots of dies. It is high abrade power of carbide alloy about eighty thousands meters by abrading every 0. 01mm thickness for producing copper cube. It's boundary lubricate state between copper and die during producing copper tube, even empty lubricate state, these states must bring surface of die coarsed. various friction destroies the force balance of float plug, the maxcrocosmic form of wear surface of die are mainly ring path and upright way. The width of vestige of die surface is about 3 m~5 m. The function of force on die is more than float plug through number simulation process, The result of simulation shows that it is reasonable for the process of producing copper tube. The process of producing copper tube and wear power of carbide cemented this both issues will not bring lots of die discard as useless. So in order to prolong the service life of drawing die will be given priority to lubrication.
