A puncher-riveter has a fixed lower part having an upper surface and a vertically displaceable upper part above the lower part and having a lower surface. A hydraulic motor vertically displaces the upper part toward and away from the lower part. A punch having a lower punch end is vertically displaceable on the upper part between an upper rest position with the lower end above the lower surface of the upper part and a lower working position with the lower end below this lower surface. A die is provided on the lower part in vertical alignment with the punch so that the lower punch end can engage in the die when the punch is in the lower working position and the upper part is displaced down toward the lower part. A rivet anvil and an embossing tool are provided on the lower surface of the upper part adjacent the punch and a rivet-setting tool has an upper tool end and is vertically displaceable on the lower part between an upper working position with its upper end above the upper surface and a lower rest position with the upper tool end below the upper surface. Thus it is possible with the same machine, simply by switching the punch and rivet-setting tool, to punch and rivet together workpieces in subsequent operations.

A puncher-riveter comprising: a fixed lower part having an upper surface; a vertically displceable upper part above said lower part and having a lower surface; hydraulic means for vertically displacing said upper part toward and away from said lower part; a punch having a lower punch end vertically displaceable on said upper part between an upper rest position with said lower end above said lower surface and a lower working position with said lower end below said lower surface, said punch having an upper end formed as a punch head and a shaft interconnecting said head and lower end, said shaft being slidably guided in said upper part, said upper part having an abutment surface relatively closely juxtaposed with said head in said upper position of said punch and relatively far from said head in said lower position of said punch; a slider displaceable when said punch is in said lower position between a blocking position between said head and said abutment surface for preventing upward displacement of said punch into said upper position and a position out of the way of said punch for permitting upward displacement of same into said upper position; a die on said lower part in vertical alignment with said punch, said lower punch end being engageable in said die with said punch in said lower working position on displacement of said upper part down toward said lower part; a rivet anvil on said lower surface of said upper part adjacent said punch; and a rivet-setting tool having an upper tool end and vertically displaceable on said lower part below said rivet anvil between an upper working position with said upper end above said upper surface and a lower rest position with said upper tool end below said upper surface.
