INSURANCE OF SUSTAINING GRIPS IN A TOOL RING FOR A NAIL MACHINE.

摘要

A method of securing support jaws (2) in a machine for the manufacture of heads in elongated bodies, including nails, screws, etc., said machine comprising at least one tool ring (10) having a rotation axis on which the tool ring (10) can be rotated, said tool ring (10) comprising at least one substantially perpendicular support surface (4) relative to the axis of rotation, in which the tool ring (10) it comprises a plurality of support jaws (2) and means for placing and securing said support jaws (2) along the circumference of the tool ring (10) on said support surface (4), in which each of said support jaws (2) comprises at least one face (12), provided with a groove (14) for longitudinally receiving in said groove (14) an elongated body, and first and second side faces (16, 18) thus how a rear side (20); characterized in that at least the second lateral face (18) forms a wedge with respect to the plane perpendicular to said at least one face (12), said at least one plane being parallel to the longitudinal axis of said groove (14), and in which The tool ring (10) further comprises a plurality of support accessories (6, 8), said accessories comprising a certain number of passive accessories (6) and a certain number of active accessories (8), and wherein said accessories Passive (6) are immovably secured to the tool ring (10), and in which each of said passive accessories (6) comprises at least a first support surface (22), said first surface (22) being placed of support at an angle equal to or less than 90 degrees with the support surface (4), wherein said first support surface (22) is adapted for cooperation with a support jaw (2), and in which each one of these accessories The active (8) comprises at least one wedge-shaped side (24) adapted for cooperation with a wedge-shaped side of a supporting jaw (2), and in which a certain number of jaws (2 ) of support, preferably the majority of support jaws (2), are each secured with the first side face (16) against a first support surface (22) of a passive accessory (6) and the rear side (20) against a support surface (4), as well as with an active accessory (8) placed against the second side face (18) of the holding jaw (2), and in which the active accessory (8) is secured to the ring (10) of tool, whereby each of said number of holding jaws (2) is secured between at least one support surface (4) in the tool ring (10), a surface (22, 23) of holding a passive accessory (6) and a wedge-shaped side of an active accessory (8), and in which dich or active accessory (8) is used to apply force on at least one support jaw (2) to secure said support jaw (2) to the tool ring (10).
