Abstract

1352513 Screw threading machines; transfer means ARTHUR EDGE & CO Ltd and W F MARSHALL 19 April 1971 [14 March 1970 13 Aug 1970] 12365/70 and 39006/70 Headings B3N and B3B A transfer unit on a screw threading machine operates as follows: starting from the position shown in Fig. 1, slide 11 carrying a workpiece holder 12 with a workpiece therein, e.g. a bolt blank, is fed towards a rotary cutting head 13, transfer jaws 17 mounted on a swinging arm 16 are moved from the intermediate station 21 to station 22 and thence by operation of piston and cylinder unit 1 to a receiving station 23; a shoot 14 has piston and cylinder units 6, 7 which operate as a gate to admit blanks singly to the transfer jaws; the jaws are then moved back to the intermediate station 21; when workpiece holder 12 reaches a returned position as shown it is opened to release the finished bolt whereupon transfer jaws are fed to delivery station 20 and the blank is transferred to the workpiece holder; the transfer jaws return to the intermediate position and a new cycle commences. Instead of a swinging arm 16 the transfer jaws could be mounted on a carriage which is movable along a horizontal rail. Further, instead of dropping a finished bolt from the workpiece holder 12 a removal arm may be supplied. A plate having a hole may be mounted in front of head 13 so that a misaligned bolt will cause the plate to operate a release valve which retracts the saddle. A deflector plate may also be operated so that the ejected bolt does not fall into the finished bolts. Automatic control is pneumatic pilot valves and suitably placed actuators. Alternatively the machine could be hydraulically or electrically controlled. Saddle 11 has a fast feed of approach toward head 13 and the feed into the cutter head is controlled by an hydraulic rate control device 113.
