Device for manufacturing curved helical springs |
摘要 |
The objects are a reliable and economical method of and device for manufacturing helical springs that are curved when unstressed from sections of wire or rod heated to coiling temperature. The spring is coiled straight and then curved it to its final shape. The device consists of a hot-coiling production line comprising a kiln (1), a series of rollers (2), a coiling bench (4), and a quenching tub (6). A tool (5) for curving helical springs (10 or 14) is integrated into the production line between the coiling bench and the quenching tub.
