Document Type and Number:
WIPO Patent Application WO/2019/003734
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for manufacturing a coil spring that can improve yields for various coil springs. The method for manufacturing a coil spring uses a coil spring inspection device and includes: comparison steps (step S2, step S5, step S8, step S11, step S14) for comparing, using the coil spring inspection device, measured coil spring measurement results data and reference data forming a reference for pass or fail in coil spring inspections and stored in advance in the coil spring inspection device; production steps (step S3, step S6, step S9, step S12, step S15) for producing correction data related to coil springs on the basis of the comparison result using the coil spring inspection device; and output steps (step S4, step S7, step S10, step S13, step S16) for the coil spring inspection device outputting the correction data produced to a coil spring manufacturing device for manufacturing the coil spring.
