Abstract

Improved device for riveting, with which a substantially cylindrical core cooperates, acting as a piercing rivet (1), optionally provided with a suitable head that receives the thrust, whose penetration end (2) is flat with edges live and produces on the first sheet to gather (4) a hole, releasing a discoidal snack of material (16) that is simultaneously pressed against the upper plane of a sufferer (6) provided with three cutting edges (7), fractioning said bite discoidal (16) in three pieces (22) for subsequent evacuation of the device.2. Improved device for riveting, according to claim 1, which is constituted by a suffering element (6) with which the perforated rivets (1) themselves collaborate, whose sufferer, in its upper part, to which the rivet faces, counts with three cutting grooves (7) extending radially from the same central point, which produce on the second sheet (5) gather three cuts (13), forming two pins (19) that are folded by the sufferer (6) by push of the rivet itself (1).3. Device, perfected, for riveting, according to claim 2, characterized in that the suffering element (6) has, in its upper plane, three constant support sectors (8) on which rest the plates to be cut and riveted. 4. Improved device for riveting, according to claims 2 and 3, characterized in that the sufferer (6) has three recesses (9), forming curved outlets designed to allow the bending of the legs (19) formed in the sheet (5), immediate to the sufferer, and also to allow the evacuation of the fragments (22) into which the bit (16) cut from the first sheet (4) by the rivet (1) is divided. 5. Improved device for riveting, according to preceding claims, characterized in that the three cutting edges (7) of the sufferer (6), when advancing the rivet (1), produce three cuts, forming three legs (21), that when sliding along the corresponding exit ramps (9) they deviate laterally, producing the riveting, which retains the set of plates (4, 5) reciprocally attached. 6. Device, perfected, for riveting. (Machine-translation by Google Translate, not legally binding)
