Abstract
1,144,178. Broaching. WELDING INSTITUTE. 26 July, 1967 [28 July, 1966], No. 33998/66. Heading B3L. In apparatus for forming a notch in a specimen for a mechanical test, the specimen 16 is clamped on a horizontal surface 10 adjacent a hole 21 through which there passes a broach 20 mounted at its lower end on a crosshead 23 and guided by a groove 34 in a block 15. The crosshead 23 is movable on guide pillars 24 by the action of rotary lead screws 26 which are driven from a motor 30 through gears 29, 28. The clamping means (Fig. 3), comprise a toggle mechanism 11 operating on an equalizing bar 13 which in turn bears against a pair of spring-loaded pins 13 which are guided by a block 15 and which bear directly on the workpiece 16. Bellows 27 protect the lead screws 26. Microswitches operable by the edge of the crosshead limit the travel thereof.
