Embodiment Construction

[0028] exist figure 1 The rivet setting tool shown in section in , comprises a housing 1 which is assembled from several parts. at the front end figure 1 There is an opening in the center left, through which the rivet mandrel 2 of the blind rivet 3 passes. The rivet mandrel 2 extends into the channel 4 of the holder 5 for the blind rivet 3 .

[0029] The holder 5 for the blind rivet is arranged in the housing directly behind the opening for the rivet mandrel 2 . The opening extends into the housing. The already mentioned channel 4 thus also accommodates the push rod 6 of the mounting device.

[0030] The holder 5 for the rivet mandrel 2 has a plurality of radial cutouts 7, figure 1 The cross section of shows one such cutout 7 among a plurality of radial cutouts. The front end wall 8 of the radial cutout 7 in the direction of the blind rivet 3 runs obliquely from the inside to the outside, as does the rear end wall 9 . The walls 8 and 9 at both ends diverge outwards.

Abstract

A rivet setter has a holder for holding a blind rivet prior to said rivet being set by means of the setter. The holder has a central cylindrical passage, the diameter of which is somewhat greater than the diameter of the mandrel. At least two, preferably three clamping jaws, which are guided in radial slots so as to be radially and axially displaceable, act on the mandrel. The width of the slot is smaller than the diameter of the mandrel.

Description

technical field [0001] The invention presupposes a rivet setting tool (Nietsetzgeröt), with the aid of which blind rivets can be set (setzen). Background technique [0002] A blind rivet is a rivet that is put in and deformed from the front side without approaching the rear side of the location at which the rivet is mounted. The deformation of the blind rivet for forming the rivet head on the rear side or in the solid material takes place by means of a rivet mandrel, at which traction takes place. This can take place by means of manually operated pliers or by means of a blind rivet tool with a drive. After installing the blind rivet, the rivet mandrel breaks (abreisen). [0003] There are also rivet setting tools that pull the rivet by pushing action at the rivet mandrel before the rivet setting tool deforms the rivet by pulling action (Zugangriff) at the rivet mandrel to form the rivet head. Press into the material to be fixed. [0004] Blind rivet tools are known in wh...
