ABSTRACT:
A fourslide metal wire and strip forming machine is provided with a removable drive motor mounted on a hinged door; a clutch shaft journalled in a plurality of bearings permitting easy removal and replacement of electric clutch and brake assemblies; a dual-speed drive shaft driven by a shiftable gear train, turning a reversible feed cam providing single and double feed cycles; a positive-action feed mechanism with resilient shock-mounting actuation for the feed carriage gliding on a low-friction ball-and-groove bushing; at least one tool-carrying angle slide cooperating with the conventional four slides converging upon the mandrel; an adjustable kingpost removable from behind the preferably vertical fourslide plane; and a supplemental "electronic handwheel" drive motor connected for reversible incremental actuation in small increments to facilitate tooling and feed assembly set-up operations. The vertical fourslide machine moves wire or strip stock through its feed mechanism and press area to its kingpost and mandrel in a right-to-left direction as viewed by the operator in front of the machine, and tooling for forming slides and press units is interchangeable with that of conventional "horizontal" fourslide machines.
