Detailed Description

In order to make the technical field person understand the solution of the present invention better, the technical solution of the present invention is further described below with reference to the specific embodiments.

Example one

The utility model provides a no locating hole pressure riveting device, includes die 1, clamp plate 3, stripper 5, location axle 6 and lower die 7, be provided with first through-hole 10 on the clamp plate 3, be provided with on the stripper 5 with die 7 complex second through-hole 11 down, wear to be equipped with location axle 6 in the die 7 down, location axle 6 is elastic construction, it can adsorb screw 2 to go up die 1.

The working mode is as follows:

work piece 4 is placed on stripper 5, and the sand grip on work piece 4 is placed on stripper 5, adsorbs screw 2 at the lower extreme of last die 1, goes up die 1 and penetrates first through-hole 10 on the clamp plate 3, and the pressure head exerts pressure to last die 1, and behind clamp plate 3 compressed tightly work piece 4 earlier, screw 2 penetrated location axle 6 along with last die 1 pushes down in, and the riveting is pressed downwards. After the pressure riveting is finished, the upper riveting head 1 is lifted, and the workpiece 4 is bounced by the stripper plate 5.
