| 摘要 | The coil spring manufacturing device includes a first continuous material mounting portion, a second continuous material mounting portion, a straightener, a cutter, a short material mounting portion, and a coiling machine. The material reeled out from a first continuous material or a second continuous material is cut by the cutter. The coil spring manufacturing device can switch a process among a first continuous material coiling process of manufacturing a coil spring by using the first continuous material, a second continuous material coiling process of manufacturing a coil spring by using the second continuous material, and a short material coiling process of manufacturing a coil spring by using the short material. | ||||||
