It not only improves the machining accuracy and surface finish, but also greatly improves the mechanical properties of the parts. The cold work hardening of the metal after cold extrusion and the formation of a reasonable fiber streamline distribution inside the part make the spline strength much higher than that processed by mechanical cutting. Through the test, the mandrel processed by the process has a load-bearing torque of 25-30%, and the accuracy is improved by two levels, achieving the national standard six-level accuracy. In addition, a reasonable cold extrusion process can form compressive stress on the surface of the part to improve fatigue strength.Comparison table 2--Torque of Spline ShaftTypeMiddle diameter of splineTorque of spline shaft (N*m)WR12 HRC38 ~42WR15A HRC38-42WR15E HRC38-4240CrNiMoa HRC28 ~3240CrNiMoa HRC32 ~3540CrNiMoa HRC3S-422010.57574834463703016267261295157224275351838037142122331839240205215095773064375375024900880997528754929522712821253142075210741322603323402287259213741961241465332340228725921374196124147539386337754279226832373985854455485421614432574648572295529157894810142537576729445Related products:    /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
