Manufactured hollow shafts joining method, involves successively positioning structural parts downwards from above, where parts are sequentially or simultaneously fixed to pipe by plastic expansion of pipe into individual sections

摘要

#CMT# #/CMT# The method involves axially threading structural parts (7) e.g. flanges, attached to a hollow pipe (6) on an arbor in an order. The structural parts are axially attached adjacent to each other to the pipe. The pipe is coaxially pushed by the arbor and is pushed via the structural parts. The structural parts are successively positioned downwards from above and parallel in a tubing axis relative to the pipe. The structural parts are sequentially or simultaneously fixed by plastic expansion of the pipe into individual sections arranged to the respective structural parts. #CMT# : #/CMT# An independent claim is also included for a device for joining manufactured hollow shafts. #CMT#USE : #/CMT# Method for joining manufactured hollow shafts. #CMT#ADVANTAGE : #/CMT# The structural parts e.g. flanges, are successively positioned downwards from above, parallel in the tubing axis relative to the pipe and fixed to the pipe sequentially or simultaneously by plastic expansion of the pipe into the individual sections arranged to the respective structural parts, thus accelerating joining process and production of the manufactured cam shaft. The method facilitates positioning and fixing of the structural parts to the pipe, so that the structural parts for positioning and adjustment to the pipe are arranged in a single step, thus shortening the process cycle and achieving inexpensive production, and hence simplifying the supply of the structural parts for positioning and adjustment to the pipe. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a simplified side view of a device to join a manufactured hollow shaft. 1 : Manufactured hollow shafts joining device 2 : Hollow shafts 5 : Expansion device 6 : Hollow pipe 7 : Structural parts.
