Device for compositely extruding spline shaft by means of medium-high frequency induction heating and vibrating and technology therefor

Abstract

The invention provides a device for compositely extruding a spline shaft by means of medium-high frequency induction heating and vibrating and a technology for compositely extruding the spline shaft by means of medium-high frequency induction heating and vibrating. The device comprises a vibrator and a medium-high frequency induction heater, wherein the vibrator is axially connected with a blank in series by a clamp, and the medium-high frequency induction heater and an extrusion die are distributed at the front of a blank feed direction. The technology comprises the following steps of: firstly, clamping a blank, wherein the clamp drives the blank to move to a spline tooth-shaped section of the blank along the feed direction to completely enter into an inner chamber of the medium-high frequency induction heater, quickly heating the surface metal of the spline tooth-shaped section on the blank to a preset temperature, continuously feeding the blank, applying axial vibration to the blank by the vibrator, forming the spline shaft in an extruding way due to the action of the extrusion die, reversely withdrawing the blank, and quickly quenching. The device has the advantages of being less in forming load, low in energy consumption, high in efficiency, good in forming quality, wide in machining range and the like.
