| PURPOSE:To enable manufacture of a high quality spring by making a tool supporting member freely movable back and forth to the direction of rolling out of a wire rod and making the position of the tool freely changeable during manufacture of a spring. CONSTITUTION:A wire rod W is sent to a wire rod working section 13 through a straightening device 7, a roll 8, wire feeding rolls 10, 10 and a wire guide 12. A bracket 28 is provided in a slide 27 which is movable back and forth to the working secton 13, and a tool supporting member 30 is attached to the bracket 28 allowing free back and forth movement in the direction parallel to the direction of rolling out of the wire rod W. A pin 29 is rotated by a liquid pressure cylinder 75 to change the position of the member 30. A tool operating motor is operated to operate and the rotate hook forming tools 22, 22, a coiling tool 33 and a slide 27 through link mechanisms 24, 34, 66, a rocking lever 36 etc. and specified working is given to the wire rod W. Then, completed spring is cut by a cutting tool 32 and dropped from a discharge port 14. | ||||||

| A method includes a spiral forming step causing a substantially linear elongated member, conveyed toward one side in a longitudinal direction of the elongated member by a pair of conveying rollers, to be engaged at one side in a second direction with a pressing member movable in the second direction so that a spiral body including the fixed coil part, the first movable coil part and the second movable coil part is formed from the linear elongated member. The spiral forming step is configured to control the position of the pressing member with respect to the second direction, based on a signal from a rotational speed sensor detecting the rotational speed of the conveying roller, a relationship between a position in the longitudinal direction of the elongated member that is engaged with the pressing member and the position in the circumferential direction after the spiral body is formed. | ||||||

| A method and apparatus for producing an end lug of a spring member formed of a strand of wire, the strand of wire is initially gripped by two clamping jaws or a pair of tongs, held between said clamping jaws and, subsequently, at a predetermined distance behind the gripping tongs, while forming a rear wire segment protruding behind the spring element, is severed. In this regard, a shaping jaw conforming to the shape of the lug is employed as the one clamping jaw of the gripping tongs, around which the wire segment is bent by means of a shaping pin that can be inserted directly behind the other clamping jaw perpendicular to the longitudinal center line of the wire segment over the latter to form the lug. The relative movements between the shaping pin and the shaping jaw required for this purpose are generated by means of program-controlled movements of the gripping tongs and/or shaping pin. | ||||||
