Arrangement for forming and transferring coils for subsequent insertion into a slotted magnetic core

摘要

A coil winding and inserting device of the type where a coil form is engaged by coil placer tooling and a flyer revolves about that form generating coil turns while previously formed turns migrate along the coil form and into the placer tooling has an improved arrangement for maintaining formed coils in position within the coil placer tooling comprising spring biased pins located about the periphery of the coil placer tooling for restricting unwinding of the coils while those coils reside in the coil placer tooling as well as wire spring members tending to restrict coil expansion axially toward the coil form and flyer. An improved wire transfer assisting arrangement is also disclosed including a coil pusher for engaging and urging any remaining coils from the form toward the placer tooling subsequent to winding with that coil pusher including a portion for engaging and maintaining the separation between selected adjacent pairs of finger elements of the placer tooling as well as outrigger portions for engaging certain ones of the coils to ensure that they are properly positioned relative to the arrangement for restricting unwinding. Actuation of the coil pusher also allows the coil form to collapse somewhat under the force of the remaining turns on that form to relieve the tension in those turns and allow their ready transfer to the placer tooling.
