Abstract: A wire coating removal device includes: a wire feed path; a pair of first rotary tools that remove a coating of the wire at a first position on the wire feed path; a first rotary drive mechanism that rotationally drives the pair of first rotary tools; a pair of second rotary tools that remove the coating of the wire at a second position; a second rotary drive mechanism that rotationally drives the pair of second rotary tools; a first tool distance changing mechanism that makes the pair of first rotary tools approach or separates from each other; and a second tool distance changing mechanism that makes the pair of second rotary tools approach or separates from each other, wherein the pair of first rotary tools remove a part of the coating of the wire, and the pair of second rotary tools then remove a remainder of the coating.

Abstract: A spring forming machine includes: a forming tool slide mechanism including a slider with a forming tool; a first lifting mechanism including a slider with a pitch tool; a second lifting mechanism including a slider with a cutting tool; a fixing base to which the wire feeder and the forming tool slide mechanism are attached; a lifting base to which the cored bar, the first lifting mechanism, and the second lifting mechanism are attached; a plurality of servo motors serving as drive sources; a controller controlling the servo motors; an individual drive control unit individually driving the servo motors; and an interlocking control unit that, when the servo motor of the lifting base is individually operated, interlocks the servo motors of the lifting base and the first lifting mechanism and, when the servo motor of the first lifting mechanism is individually operated, does not interlock the servo motors thereof.
