Abstract

1351539 Bending wire and strip; shearing EVG ENTWICKLUNGS U VERWERTUNGS GmbH 20 July 1972 [12 April 1972] 34051/72 Headings B3E and B3W [Also in Division F2] A pivoted wire or strip bending tool 20 is angularly reciprocated by a drive from motor 21 which includes linkwork adjustable by spindle 32 to adjust the angular throw of the tool. Fig. 3 shows, in side view and extended in the direction of arrow P, the linkwork of Fig. 1. Motor 21 drives a flywheel 23 connected by a clutch (not shown) and toothed gears 23, 25, and eccentric 26 to a connecting rod 27. Rod 27 is pivoted at 37 to a working link 28 and swing link 29. The former operates tool 20 through bell crank 35 and link 38, and the latter is pivoted at 33 to an adjustment lever 30, one end of which has a fixed pivot 31, while the other end is located by threaded spindle 32. The distances between pivots 34 and 37, 33 and 37, 31 and 33, and 31 and 36 are preferably equal. The throw of the tool is adjusted by manual or programmed rotation of spindle 32, being zero when pivots 33, 34 are coaxial. The machine also includes former 19, feed rollers 2, 3, straightener 14, shears 17, 18 operated by motor 62 through flywheel 64, eccentric 67 and connecting rod 68 and controlled by measuring drum 15, and an ejector pin 51 operated by piston and cylinder 86, 89. (For Figures see next column.)
