Abstract

1,273,659. Press feed mechanisms; metal strip feeds. DIAMOND DIE & MOLD CO. 30 July, 1970 [8 Sept., 1969], No. 36976/70. Headings B3Q and B3W. A feed mechanism for a machine tool, e.g. a press, including a tool slide 14, comprises a feed slide 24, a timing piston and cylinder device 76, 66, a loading piston and cylinder device 62, 60 and passages 68, 72 connecting the cylinders. A latch arm 44 holds the slide 24 during an operating stroke of the slide 14, and as the latter moves upwardly after completing its operating stroke an arm 56 engages the latch arm to release the slide. Springs 42 move the slide 24 to feed a component 20 to the work station by a feed dog 26 at a rate determined by the flow of fluid through the passage 72. The speed of the stroke may be varied by a cam (110) engaging a spring loaded needle valve (100) to provide a smooth acceleration and deceleration of the feed slide, Fig. 7 (not shown) and the stroke of the slide is adjusted by nuts 90, 92. On the next downward stroke and near the end thereof, the tool slide 14 engages the piston 62 to return the feed slide 24.
