Rectangular wire coiling machine

Abstract

A coiling machine configured to coil semi-rigid rectangular wires without using a core to wind the wire thereonto, yielding a free-standing coil, is described. The coiling machine comprises a wire bending mechanism including a wire holding assembly for selectively immobilizing a wire and a wire bending assembly for bending a selected portion of the wire at an angle while the wire is immobilized by the wire holding assembly; a wire feeding mechanism for receiving the wire from a wire drawing mechanism and for feeding a length of the wire to the wire bending mechanism; and a controller coupled to the wire drawing mechanism, wire bending mechanism and wire feeding mechanism to control their operations for sequentially bending the wire at predetermined positions therealong so as to yield a coil of wire having a predetermined geometry.

Description

technical field [0001] The present invention relates to wire winding machines. The invention more particularly relates to a machine for coiling semi-rigid wire without the use of a core, resulting in free-standing coils of wire. Background technique [0002] Wire winders are well known in the art. They are generally provided with a rotating core on which the wire is wound. In some cases, the core is part of the finished product. In this case, the wire coil is completed when a predetermined number of turns are wound thereon. [0003] In other cases, such as when producing air coils, the core is not part of the finished product. In such a case, the coil of wire must be removed from the core. A number of techniques have been devised to accomplish this process. For example, the core may be made in separable parts, so designed as to allow a reduction in the size of the core, thereby facilitating removal of the core from the coil of wire. [0004] Such coilers are not well ...

Problems solved by technology

In fact, the force required to hold these types of wire on the rotating core tends to weaken or destroy the electrical insulation of the wire, rendering the coil of wire unusable
