| 341 | Universal compression spring former | US11470602 | 2006-09-06 | US07353680B1 | 2008-04-08 | Jin-Tarng Huang |
| The compression spring former disclosed by the present invention contains an external diameter mechanism, spacing mechanism, wire-feeding mechanism, cutting mechanism, length-detecting mechanism, sorting mechanism, and microcomputer control mechanism. Within the working range, specific springs can be formed simply by inputting the parameters describing the external diameter, spacing, roll number, and other allowance requirements. The control mechanism has a built-in length detecting and automatic sorting mechanism, which can modify the spring spacing according to different free heights, ensuring the allowance of free height. The cutter has a working mode for repeated cutting. The lowest point of the cutter shaft is set to “0” degrees for cutting the springs. If the cutter swings from positive 20 degrees to negative 20 degrees, or from negative 20 degrees to positive 20 degrees, the spring will be cut. That is to say, a spring is produced in every rotation of 40 degrees. | ||||||

| 354 | Procedure and apparatus for the optimized manufacture of coil springs on automatic spring winding machines | US849604 | 1997-06-03 | US5865051A | 1999-02-02 | Uwe Otzen; Hans-Jurgen Schorcht; Mathias Weiss |
| Procedure and apparatus for the optimized manufacture of coil springs on automatic spring winding machines. It is the object of the present invention to offer both a procedure and an apparatus by which even in case of fluctuating values of the wire parameters high accuracies during the spring manufacture are guaranteed and simultaneously the scrap is minimized. The solution to this problem is that prior to the winding the wire parameters are determined and the measuring results are used directly for the adjustment of the position of the winding pins or winding rollers and/or the pitch wedge, and that the wire between the uncoiling device and the guiding assembly forms a loop whereby the lateral deflection of this wire loop is measured by a recognition unit and the uncoiling device carries out an additional movement controlled by the recognition unit. The invention is suitable for continuous inspection and correction of errors occurring on spring wires for the optimized manufacture of coil springs on automatic spring winding machines. | ||||||

| 359 | Closed loop wire feeding and measuring apparatus and method of operating same | US480770 | 1990-02-15 | US5060395A | 1991-10-29 | Thierry Pepin |
| Apparatus (10) comprising rotatable feed belts (16,18) driven by a reversible electric servo-motor (20) which is operated by a pre-programmed electronic controller (30) feeds accurately measured lengths of a wire strand (12), regardless of wire slippage which may occur relative to the feed belts. Controller (30) receives feedback signals from an encoder (22) indicative of the distance and direction wire (12) actually moves, compares the feedback signal with stored data and recognizes the amount and direction of any wire slippage. Wire movement less (or more) than the desired length results in forward (or reverse) operation of servo-motor (20) and feed belts (16,18) to move the wire forward (or in reverse) until the desired length is reached. Encoder (22) is operated by a measuring wheel (24) which engages and is rotated by wire strand (12) itself during forward or reverse movement. Either "run-out" of wire strand (12) or too large a "following error" shuts down the apparatus. Measuring wheel (24) is movable by a positioning cam (28) into direct engagement with feed belt (18) for set-up and test of apparatus (10) before a wire strand is present. The feed belts (16,18) are adjustably movable by a pneumatic actuator (26) relative to each other to tightly engage a wire strand regardless of wire diameter. A tachometer (21) on servo-motor (20) counts the lengths fed. | ||||||
