Abstract

1358424 Bar-stock feeding; multi-spindle lathes EUNIPP AG 15 Oct 1971 [17 Dec 1970] 48174/71 Headings B3B and B3T Bar feed apparatus in a multi-spindle automatic lathe comprises a plurality of bar guide tubes 3 corresponding to the number of spindles in the lathe spindle drum and mounted in at least two carriers rotatably supportable coaxially with the spindle drum 4, each tube being longitudinally divided into two half portions 31, 32 which are openable when each tube reaches a bar loading position as the carriers rotate with the spindle drum, a bar magazine 19 being provided with its outlet adjacent the loading position and a feeding device 20-22 for supplying bars to each tube as it reaches the loading position. The sequential opening and closing of the guide tubes in the loading position is effected by a cam 12 rotatable with a shaft 9 which actuates a lever 7 attached to one half portion of the guide tube, the tube portions being released and clamped in the loading station sequentially with the cam and lever mechanism by a cam 17 on shaft 11 which by way of a spring biased toothed member 13 engages or disengages tooth 133 and slot 71 in the lever 7. The loaded bar is fed by a coarse pitch screw 28 having a pusher assembly 23, 26 thereon which is displaceable along the screw with rotation of the screw by motor 30. Means is respectively provided to receive the residue of a remaining bar which is ejected by the new bar as it passes through the spindle, to collect the end portion of the new bar which, due to damage, may produce a substandard workpiece, and to operate a bar stop to move it into and out of its operative position, Figs. 12, 13 and 14 (not shown). The above means and the operation of the bar feeding apparatus is preset, e.g. by programming, to effect sequential cyclic operation of the machine tool and bar feed apparatus. In a further embodiment, Fig. 15 (not shown) creepdrive means is provided to orientate the respective lathe spindles to facilitate ease of insertion of polygonal section bar stock.
