Development and application of dedicated aluminum alloy guide wheels for cable production equipment
Three different processes for preparing Φ290×28 the material composition,mechanical properties,and microstructure of the guide wheel of the horizontal wire winding machine were tested,and the production cycle,production cost,and application of the guide wheel were analyzed.It was found that the main chemical components of the customized 6061 aluminum alloy material were 1.12％Mg,0.71％Si,0.11％Cu,1.25％Zn,and 96.34％Al,1.25％Zn greatly improved the stamping formability of the aluminum alloy.The hardness of the guide wheel prepared by precision forging technology is 124HV,the tensile strength is 325MPa,the elongation is 14.25％,and the material only fractures when the strain reaches 14.8％.The microstructure is uniform and dense,without any loose or porous defects.Compared with the two processes of using aluminum rods for mechanical cutting and casting to prepare guide wheels,the hardness,tensile strength,toughness,and microstructure of the guide wheels have been significantly improved.The comprehensive mechanical properties of the guide wheels are good,the appearance is beautiful and smooth,the dynamic balance is good,the overall quality is good,and the production cost is reduced by more than 50％,with a long service life.It can be seen that the optimal production process for guide wheels is to use precision forging of aluminum wheel blanks using molds for rapid forming,and to prepare guide wheels through T6 heat treatment and surface strengthening.
