Wire shaping apparatus and method of shaping a wire

Abstract

Apparatus for forming wire components, which are in this example springs, comprises a supply station (), for supplying spring forming material, such as metallic wire W. The supply station includes a pair of guide rollers () and pair of driven feed rollers (), mounted on a heavy support plate (). The wire is fed through a flexible sheath FS to a remotely located wire shaping device, in particular a spring forming device, comprising forming tools (), a pitch control tool () and a cutter (). The forming tools () and the pitch control tool () form the wire into a spring S, which is cut from the supply of wire when it is complete. The tools () and cutter () are controlled remotely from a control station () via a bundle of flexible control cables (), which may include a power cable. The spring forming deviceis mounted on a positioning member (), such as a robot arm or moveable table, configured for three-dimensional movement, and/or optionally adjustments in inclination. Without the heavy plate () and rollers (), the spring forming device () is sufficiently light in weight and compact as to be moved by the positioning member () to a location in which springs are to be used, thereby avoiding the need for transportation apparatus to convey the springs from the place where they are formed to the place where they are to be used.
