Abstract:
1. A cable hanger production system in which a Z-winding spiral and an S-winding spiral are alternately and continuously formed along an axis via a switching part, the cable hanger production system comprising: a housing having a cylindrical space in which a hanger wire is supplied from one end of the housing and the hanger wire is sent out from the other end thereof; and at least five spiral forming dice which are accommodated in the cylindrical space of the housing such that the spiral forming dice are adjacent to each other and configured to rotate independently from one another, wherein each of second and subsequent spiral forming dice as counted from the hanger wire supplying end of the housing includes: a bottom face forming a shape corresponding to a curvature of the Z-winding spiral and the S-winding spiral on a plane intersecting with the axis at right angles between an inner peripheral face of the housing and the bottom face, the bottom face gradually becoming narrower from both sides of the spiral forming die in its longitudinal direction toward a central portion thereof; and a Z-winding wall face forming a shape corresponding to a pitch of the Z-winding spiral and an S-winding wall face forming a shape corresponding to a pitch of the S-winding spiral, which are inclined with respect to the plane and the axis, the Z-winding wall face and the S-winding wall face intersecting with each other at an intersection of a center of the spiral forming die in the longitudinal direction thereof, the Z-winding wall face and the S-winding wall face extending along a side edge of the bottom face, and the first spiral forming die as counted from the hanger wire supplying end of the housing includes: a latter half thereof in its longitudinal direction, the latter half including a bottom face, a Z-winding wall face and an S-winding wall face in the same manner as those of latter halves of the second and subsequent spiral forming dice in the longitudinal direction; and a first half thereof in its longitudinal direction, the first half including an introducing portion extending along the axis, the introducing portion connected to a front portion of an intersection in the bottom face of the latter half in the longitudinal direction; and a front end of the introducing portion including a hanger wire introducing inlet.
