Method for manufacturing cams for built camshafts

摘要

#CMT# #/CMT# A fabrication method involving thermal molding of a CAM (11) including aperturing for the CAM boring (13), axial and radial calibrating of the CAM by positioning in a matrix die to define the calibrated CAM contour (12), and inserting a pin into the CAM boring which defines the calibrated CAM boring. The CAM is axially shortened between a lower punch, which is placed between the matrix die and the pin on which the CAM (11) is placed with its first front face (14), and an upper punch, which is inserted between the matrix and the pin, which acts on the second front face of the CAM. #CMT#USE : #/CMT# For fabrication of CAMs for CAM shaft. #CMT#ADVANTAGE : #/CMT# The number of chip-cutting processing steps can be reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# Schematic representations of a calibrated CAM are shown. 11 : CAM 12 : CAM contour 13 : CAM boring 14 : Front face 16 : Flange.
