ABSTRACT:
A coiling device for spring coiling machines, having exchangeable elements that contain adjusting screws. Each coiling pin is mounted in a receptacle so as to rotate therewith and so as to be able to rotate therein about its longitudinal axis after a clamping screw is loosened, and to be capable of moving in its longitudinal direction by means of a set screw, and whereby each coiling pin receptacle is mounted in or on a coiling pin holder, by means of which the coiling pin held in the receptacle can be pivoted in a controlled manner by means of set screws, and can be changed in position by means of an adjusting slide that mounts the coiling pin holder, by means of at least one set screw. One or two such coiling devices are preset in one finger or two finger spring coiling machines to produce helical springs from endless wire. An adjusting device is also provided for coiling tools on spring coiling machines having a coiling device.
