Embodiment Construction

[0015] As shown in Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5, a self-piercing riveting method for hollow rivets, the materials to be riveted by this method are two plastic thin plate parts 1 and 2, when this method is riveted The upper end of the tool used is a punch 3, and the lower end is a base 5 with a "W"-shaped annular groove 4 in the longitudinal section. When riveting, the riveted part is located between the upper punch 3 and the lower base 5, and the hollow rivet The brim of the brim of the rivet 6 is in contact with the upper punch 3, and the riveting body with the open end is downward, and the hollow rivet 6 runs downward under the action of the upper punch 3, and continues after the lower end of the hollow rivet 6 is in contact with the riveted piece. Running downward, the riveted part will be plastically deformed under the action of the upper punch 3 until the upper riveted part is pierced by the hollow rivet 6, and the lower riveted part will also be pla...

Abstract

The invention discloses a self-punching riveting method for a full tubular rivet. In a riveting process, riveted pieces are located between an upper plunger tip and a lower base, the edge of the full tubular rivet is in contact with the upper plunger tip, a rivet body with an opening end is downward, the full tubular rivet moves downwards under the action of the upper plunger tip and keeps moving downwards after the lower end of the full tubular rivet is in contact with the riveted pieces, and the riveted pieces is subjected to plastic deformation under the action of the upper plunger tip until the upper riveted piece is pierced by the full tubular rivet and the next riveted piece is also subjected to plastic deformation under the action of the upper plunger tip to match with an annular groove in the lower base to finish the riveting work. The riveting method disclosed by the invention has the advantages that the riveting method is simpler, the sealing performance of the riveted pieces is greatly improved, the shapes of the riveted pieces are consistent after the riveting operation, and the riveted pieces are very beautiful.

Description

technical field [0001] The present invention relates to the technical field of rivets, and more specifically relates to the technical field of using methods of hollow rivets. Background technique [0002] The hollow rivet is composed of a rivet body and a brim located above the rivet body. The rivet body is hollow. When in use, first drill a hole on the riveted piece to be riveted, and then put the hollow rivet in the drilled hole. Then put one end of the brim of the hollow rivet on the top, and finally use a press tool to press down the end of the hollow rivet opposite to the brim, and the hollow rivet will flang outward under the action of pressure, thus playing a role of riveting. effect. The shortcomings of this kind of riveting method are: 1. The riveting process is troublesome. Before riveting, it is necessary to drill a hole, and then perform riveting at the drilled hole, so the riveting efficiency is difficult to improve; Therefore, the sealing performance of the r...
