Abstract

The invention relates to a device (11) for flanging the end (13) of a metal tube (15) to obtain a circumferential surface extending outwardly from the metal tube (15) at right angles, the device (11) Comprising a flanging tool (17) adapted to be attached to an end of a metal pipe (15), the flanging tool (17) having a guide arrangement (31) drivable by shafts (33, 48) of the guide arrangement (31) ) and the extrusion element (27) attached to the guide arrangement (31), the guide arrangement (31) comprising a displacement device (35) driven by the rotation of the drive shaft (33, 48), the displacement device (35) with The pressing element (27) is displaced in an outward radial direction (37) with respect to the metal tube (15). In order to prevent the device (11) from being damaged, if the torque applied to the drive shaft (33, 48) is not limited, it is recommended that the displacement means (35) be arranged for, if the radial end position of the extrusion element (27) is reached , the displacement of the pressing element (27) is stopped and the rotation of the drive shaft (33, 48) is permitted when this end position is reached.

Description

technical field [0001] The invention relates to a device for flanging the end of a metal tube to obtain a circumferential surface extending outwardly from the tube at right angles. Background technique [0002] Apparatus for flanging the ends of metal pipes are known in the art. This device has a mechanism for moving the pressing element with the flanged pin in radial direction with respect to the tube. The mechanism is actuated by rotating a rod. If the radial movement reaches the end position, the rotation of the rod is blocked. This known device can be damaged when a high torque is applied to the rod when the end position has been reached. Contents of the invention [0003] The object of the present invention is to provide a device for flanging the ends of metal pipes which is not damaged when the torque applied to the drive shaft of the device is not limited and which can be manufactured cheaply. [0004] According to one embodiment, there is provided an apparatus ...
