Abstract
1,218,922. Rolling. TAP & DIE DEVELOPMENT CENTRE Ltd. 19 July, 1968 [19 April, 1967; 30 Aug., 1967], Nos. 15194/67 and 39619/67. Headings B3A and B3M. A drill or reamer rolling machine described in Specification 1,070,111 is provided with a rod 20 which supports the blank and is withdrawn before the end of rolling. The blank is radially located in the rolling station by a collet 18. The supporting rod 20 is reciprocated by a cylinder B which in turn is reciprocated by a cylinder A. The collet preferably also supports the blank before the rolling so that the rod 20 can be withdrawn prior to rolling. The collet has three radial jaws (24), Fig. 5 (not shown), each with rollers 36. A pin (26) on each arm is guided in an inclined slot in a plate 30 which is rotated by a cylinder (D), Fig. 4 (not shown), to move the jaws radially. The cylinder B is mounted on a carriage 38 slidable on rods 42, 44 and rotatable about the rod 42 by a cylinder (C), Fig. 6 (not shown). The rolled blanks are discharged down a shoot 56 in line with a leadin shoot 54 pivoted with the cylinder B so that after removal of the support rod 20 the shoot 54 is positioned under the blank. The rolling dies are each mounted on a slide (8), Fig. 2 (not shown), reciprocated by cylinders (E) as in Specification 1,070,111. The cylinders are operated in sequence by switches triggered by the cylinders to control solenoid-operated valves.
