Abstract
A method of forming a sliding spline-type joint using magnetic pulse forming technology includes providing a female driveshaft member and a splined insert having inwardly formed splines. A male driveshaft member is provided having outwardly formed splines engageable with the insert. A mandrel is provided having outer ribs similar to the outer spline profile of the male driveshaft member. An inductor is provided which is energized to create a pulse magnetic field. The insert is placed over the mandrel. The female driveshaft member is disposed over the insert, and both are placed inside the inductor. The inductor is energized to deform a portion of the female driveshaft member over the insert to form an array of crimps for permanently connecting the female driveshaft member with the insert. The male driveshaft member is engaged into the insert to provide a sliding spline-type of slip joint.
