Abstract: A computer controlled wire coiling machine having three separately controllable motors for controlling wire feed, pitch tool operation and diameter tool operation. The machine includes a computer having a keyboard for setting predetermined parameters thereat regarding wire feed, spring pitch and spring diameter in constructing a predetermined spring. Three separate control signals are taken from the computer corresponding respectively to and for operating the three motors to thereby carry out the desired steps in forming the predetermined parameters that have been established.

Abstract: In a multi-slide wire and strip forming machine, an improvement that enhances the flexibility of the machine primarily from the standpoint of providing increased forming time relative to feeding time. The machine includes a wire forming means operable at the work station in response to the machine camshaft and operable over a predetermined forming. Wire feeding means is also included operable in response to the camshaft over a predetermined feeding period. An improved gearing arrangement is provided intercoupling the camshaft and the wire feeding means and configured to provide during a full camshaft rotation, different intervals of the predetermined forming and feeding periods, respectively.

Abstract: In a wire working machine particularly one for forming torsion springs, an improvement that enhances the flexibility of the machine. The machine includes a wire former operable at the work station in response to the machine cam shaft and operable over a predetermined forming period. A wire winder is included also operable at the work station and operable in response to the cam shaft over a predetermined winding period. An improved gearing arrangement is provided intercoupling the cam shaft and the wire winder and figured to provide, during a full cam shaft rotation, different intervals of the predetermined forming and winding periods, respectively.

Abstract: A machine for coiling wire to form any one of a number of different size, type and configuration of coil spring and comprising a machine frame in which is mounted a driveshaft, intermediate shaft, camshaft, and feed roller shafts. At a work station of the machine appropriate coiling dies are supported along with one or more cutters mounted adjacent thereto. The wire is fed to the work station via a pair of feed rollers driven at variable speed, preferably by an elliptical gear drive, wherein the feed speed is at a maximum during coiling and decreases to a minimum feed speed for cutting. Wire feed is synchronously interrupted at cutting by means of a cam arrangement that briefly disengaged the feed rollers. This variable speed drive enables a high duty cycle of operation and also enables start up (feed rollers engaging) at reduced speed so as to minimize wire distortion.

Abstract: A deflection coiling attachment for a wire winding machine particularly adapted for the making of complex spring configurations employing first and second separately controllable feed means comprising a feed snubber adapted for bi-directional movement and a feed roller mechanism adapted for uni-directional operation. The two separate feeds operate in sequence. In the disclosed embodiment the work station has supported there at a deflection head for forming spring coils, a bending tool and bending anvil for forming spring bends, guide members and a cutting tool. The feed roller drive is cam operated primarily for drive of the wire during the spring coiling sequences. The bi-directional snubber feed controls wire movement for other actions such as during bending sequences.
