Abstract

1,272,503. Angular bending. K. HACK. 19 Aug., 1970 [19 Aug., 1969], No. 39869/70. Heading B3E. A device for bending a wire to form a hook comprises a rotatable bending tool 23 attached to a spindle 13, an axially movable adjusting piston 2 which is screw-threadedly engaged with the spindle so that the spindle is rotated on relative axial movement between the piston and spindle, and stops 11 and 21 associated with the piston and spindle respectively to define the limits of axial movement. The device is operated from the position shown in Fig. 1 by feeding pressure medium into cylinder space 26 so as to move the piston 2 in the direction of arrow 34. Fluid pressure is also applied to cylinder space 25, thus exerting a force on the spindle in the direction of arrow 34 so that the spindle, together with the bending tool 23, is moved axially by a distance corresponding to the distance between end face 37 and the inner face of cylinder cover 14. At this position wire is introduced between a claw 43 and mandrel 41 of the bending device after which the piston is moved further in the direction of arrow 34. Since the piston and spindle are screwthreadedly engaged, movement of the piston relative to the spindle causes the spindle to rotate about its longitudinal axis so that the wire in the tool 23 is bent through an angle corresponding to the angle of rotation. The stop 11 abuts the cylinder cover 6 on completion of the bending operation. Pressure is then reduced in cylinder space 26 to return the spindle and piston to their starting positions. In another embodiment the spindle is fixed axially.
