| 抄録 | 本研究は，線ばねの寸法精度に影響する要因を究明することにより，高精度な線ばねの設計指針を得ることを目的に行われた。その結果，主に１）フィードローラ加圧力，２）コイリングピン位置，３）芯金形状，４）リールスタンド位置などの影響要因を明らかにし，さらにスペクトル解析により，線ばねの寸法精度に影響する要因を材料，機械の面からも追求している。 |
| Abstract | In spite of a demand for an improvement in
the dimensional accuracy of compression coil
springs formed with an automatic coiling
machine, factors affecting the dimensional
accuracy of compression coil springs have
not yet been clarified. Under the circumstances
the assurance of the dimensional accuracy
of compression coil springs has been left
to skilled workers. To improve these circumstances, the Research Committee on Compression Coil Forming was established in July of 1990 and implemented to make clear factors affecting the dimensional accuracy of compression coil springs until June of 1997. The purpose of this paper is to show the results of experiments of the committee conducted to demonstrate the influence of loop uniformity, shapes and positions of coiling tools, and initial tension of compression coil on the free height dispersion of compression coil springs which had been taken up from among other factors. |
