发明名称 Method, for shaping to shape end of hollow shaft, involves positioning element in hollow shaft, using medium to generate pressure and expand shaft and die to push element to connect it to shaft
摘要 The method involves positioning an element (5) in the hollow shaft, which has an outer diameter (DE) that is approximately equal to the inner diameter (Di) of the hollow shaft at at least one position. After the hollow shaft and the element have been inserted in a tool (4), the hollow shaft is filled with a medium to generate pressure and is expanded to fill the tool mould. At the same time, a die (6) is pushed axially against the end face of the hollow shaft to push material around the element and connect it positively and not-positively to the hollow shaft. An Independent claim is included for an element to fit in the hollow shaft to implement.
