Abstract
1394772 Bending EVG ENTWICKLUNGSUVERWERTUNGSGESELLSCHAFT mbH 30 April 1973 [2 May 1972] 20464/73 Heading B3E A machine for bending rod or strip, e.g. concrete reinforcements, comprises two bending heads of adjustable separation, one head nearer an infeed path being fixed and the other head being pivotable about the location of the first head, the pivotal movement and the bending motions of the heads being coupled so that the two heads make simultaneous equal and opposite bends, and the second head and a bending tool - of the first head being movable out of the plane of bending. The apparatus of Figs. 6 and 7 is intended to produce the reinforcement of Fig. 2, rod being fed to the machine along line V-V through a feed device, straightener, and measurer operable to control the feed and a shear device (not shown). The leading end of the rod is formed to a hook H by rotary tool 30 and mandrel 31 operated by worm drive 32, 33 and lowerable to inoperative position by cylinder Z 4 . The two bends at P1 and P2 are formed by two bending heads respectively comprising mandrels 24 with rotary tools 17, and mandrels 12 with rotary tools 13. Mandrels 24 are mounted on or integral with frame member 3, and tools 17 and mandrels 12 are on an arm 5 pivoted on frame member 3, while tools 13 are on arm 13a pivoted on arm 5. Frame 3 with both heads can be raised and lowered by cylinder Z 2 , and the arm is pivotable by motor 28 through pinion 26 and sector 25. Arm 13a is driven by bevel gears 4, 9, 11, 15, so that operation of motor 28 results in the equal and opposite bends P1, P2. The heads are lowered and recentered, the rod advanced, the heads raised, and bends P3, P4 made by reverse operation of motor 28. Finally the second hook H is formed in any desired fashion. In another embodiment, Fig. 5 (not shown), the first hook H is made by the first head, for which purpose the mandrels (16) and tools 17 are mounted independently of frame 3, so that when the frame is lowered, the first head can be in the operative position to form the hook, and when the frame is raised, tool 17 and arm 5 are coupled for simultaneous rotation.
