Abstract
A nut punching apparatus has a striking punch (1), a caulking die (2), a nut feeding guide (10) having a punch passage (11) and a nut delivery opening (12) perpendicular to the passage, and a driving means (14) moving the guide along the punch. The nut `N` fed through the opening is pushed into a transfer zone located ahead the punch (1) while the guide (10) is at its foremost position. This guide is retracted to its rearmost position to allow the punch to cooperate with the die (2) to punch the nut `N` onto a metal plate `W`. The apparatus has a positioning pin (20) through the punch so that its fore end portion reciprocates taking a foraward position ahead the punch and a retracted position. The pin (20) penetrates a threaded bore of the nut `N` at the transfer zone, such that the projected fore end portion of the pin (20) passing through the nut `N` engages with a positioning aperture (30) formed in the metal plate `W`.
