Abstract (en)
[origin: CA1182665A] A device is disclosed for joining metal sheets by a rivetting-type method The device has a female die and a male die which can be moved in the direction of the female die by means of a press, the sheets being superposed face-to-face between the dies. The male die comprises a punch provided with cutting edges and the female die comprises counter-edges and an anvil which is set back behind the counter-edges and on which the material forced through the counter-edges by the punch is pressed to flow behind the incision rims, whilst the counter edges yield laterally and, after the joint has been lifted out of the female die, are returned again into their cutting position by means of spring tension. The counter-edges are formed by the free end rims of leaf springs which are clamped on one side and extend parallel to the movement of the male die.
