The Times design, completed the light trucks steering knuckle forging process arrangement, process Compilation and forging die design technical specification, the products material is 40Cr.Steering knuckle forging process design, complete is material of free forging blocking, forging hammer forging and eventually gets forging, trimming press trimming process. This paper firstly product image and molding process characteristics are analyzed, sure to use electro-hydraulic forging hammer forging, use with pretensioners on forging type slots and end the mould forging type slot machine forging process method, end according to determine the size of parts machining surface shape to reserve machining allowance, according to materials look-up table determined the heating temperature, temperature, final forging beginning temperature of forging, determines the weight of the forging of forgings, according to the estimate, and force the forging stroke forging equipment choice, the punch molds for trimming blade, concave die size, finally, using the calculated according to the engineering drawing standards CAD tools software draw forging tool graph, forging die step womb graph, forging die figure, trimming mould figure, compiled the complete forging process.Keywords: Free Forging Blocking; Tire Mold; Machining Allowance; The Blade Size Calculation; Forging; Eventually Gets Forging; Forging Work StepsII
