Patent Searching and Data


Title:
金属管の端部をフランジ加工するデバイス
Document Type and Number:
Japanese Patent JP2014512271
Kind Code:
A
Abstract:
The invention refers to a device (11) for flanging the end (13) of a metal tube (13) to achieve a circumferential surface extending outward at right angles from the tube (13), comprising a flanging tool (17) adapted to be attached to the end of the tube (13), the flanging tool (17) having a guiding arrangement (31) drivable by a shaft (33, 48) of the guiding arrangement (31) and a pressure element (27) attached to the guiding arrangement (31), the guiding arrangement (31) comprising shifting means (35) driven by the rotating (89) shaft (33, 48) for shifting the pressure element (27) in an outward radial direction (37) with respect to the tube (13). In order to prevent the device (11) from being damaged if a torque applied to the shaft (33, 48) is not limited, it is suggested that the shifting means (35) be arranged for stopping shifting the pressure element (27) if a radial end position of the pressure element (27) is reached and permitting the rotation (89) of the shaft (33, 48) when the end position is reached.
