Abstract

The invention provides a four-die ultrasonic incremental extruding rolling compound molding apparatus for a spline and a technology thereof. The apparatus comprises a front apex and a die and spline integrated apex . The front apex and the die and spline integrated apex clamp a workpiece tightly. Four incremental extruding rolling compound molding dies are equidistantly arranged in 90 degrees in an array way along a peripheral direction of the workpiece. A spline section of the die and spline integrated apex and the incremental extruding rolling compound molding dies are mutually engaged and transmited, and a back end part of the die and spline integrated apex is axially added in series with an ultrasonic vibration apparatus. The technology steps are that: firstly, the workpiece is clamped; secondly, axial direction ultrasonic vibration is carried out on the workpiece, then the four incremental extruding rolling compound molding dies start to rotate in the same direction synchronously; thirdly, the workpiece is axially fed, and ultrasonic incremental extruding rolling compound molding of the spline on the workpiece is completed by the ultrasonic vibration apparatus that axially added in series and the four incremental extruding rolling compound molding dies; and lastly, material discharging is carried out. The apparatus and technology in the invention have the advantages of small molding force of the spline, high molding precision and surface quality, high production efficiency, large processing range and the like.

Description

technical field [0001] The invention belongs to the technical field of advanced material forming, and in particular relates to a spline four-mold ultrasonic incremental extrusion-rolling composite forming device and process. Background technique [0002] Splines are parts used to transmit motion and torque between shafts in mechanical systems. As a connection method with high connection strength, compact structure and high reliability, spline connection is widely used in many mechanical industries, such as aerospace Aviation, automobiles, tractors, ships, machine tools, construction machinery, etc. [0003] With the rapid development of the automobile industry, the demand for splines has increased rapidly and the requirements for use have been continuously improved, which poses new challenges to the processing technology and equipment of traditional splines. The processing technology of splines is mainly divided into traditional cutting and plastic forming processing. The t...
