Patent ID: 8752272

Claim:
A method for molding a plug and a hose or a pipe, wherein the plug is part of a pipe connection and the pipe connection is constructed as a sealing plug-in connection between a connecting piece and the plug, which can be locked with the connecting piece, wherein the plug includes an outer part and an inner part connected to each other in one piece and a rear free end of the plug forms an annular gap, the method comprising: detecting and recording a deformation force acting on each of a plurality of expanding jaws of an expanding device during a step of molding of the plug and the hose or the pipe; further molding of the plug and the hose or the pipe in dependency on the deformation force recorded in said recording step, as a result of which a constant molding degree is achieved in case of plugs and hoses or pipes with varying wall thicknesses; monitoring the deformation forces to detect breakage of the expanding device; monitoring a tightening torque of a plurality of fastening screws of the expanding jaws; monitoring the deformation forces to detect breakage of the plurality of fastening screws of the expanding jaws; monitoring the deformation forces to detect variations in the wall thicknesses of the plug and the hose or the pipe; monitoring the deformation forces to detect cracks in the plug and the hose or the pipe; and minimizing tolerance with regard to concentricity; whereby the molding steps are performed by a path-dependent power control system.
