Abstract

926,576. Thread rolling. LANDIS MACHINE CO. Nov. 21, 1961 [Dec. 6, 1960], No. 41581/61. Class 83 (4). A rolling head, suitable for rolling tapered threads on workpieces, comprises a rotatably driven body 20 on which are mounted a plurality of die holders 40, the holders having shafts on which are rotatably mounted dies 58 on axes spaced from the pivotal axes of the holders, and radially projecting arms which are movable circumferentially of the body 20 to pivot the holders 40 and thereby displace the dies 58 radially. The body 20 is rigidly mounted on a motor-driven flange 22, and a ring 35 is slidable along the body 20 on rods 46 such that when the ring 35 is held stationary during rolling, rollers 76 on the die holder arms follow cam slots 82 in the ring to slowly move the dies 58 away from the workpiece axis to produce a tapered thread. When the rollers have reached half-way along the slots the head is stopped and the ring 35 moved away from the work to quickly withdraw the dies radially, the slots being at a steeped angle to effect this. The shafts of the dies are inclined with respect to the axes of the trunnions 38 and 42 by the thread helix angle. These trunnions are lubricated by means of passages 62 and nozzles 66. A stop (Fig. 8, not shown) is used to adjust the limit of movement of the ring 35. A smooth tapered surface may be rolled, the head in this case being moved axially rearwardly.
