Problems solved by technology

The traditional riveting method is to insert rivets into the holes of two metal parts. This method of riveting has high riveting costs. Another method is to forge a bump on a metal part and rivet it into the In the hole of another metal component, although this method reduces the number of riveting components and reduces the cost, it will cause the defect of unstable connection

Embodiment Construction

[0026] The invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1-6 As shown, a metal riveting process includes a first metal piece 1 and a second metal piece 2 that need to be riveted, and the steps are as follows:

[0028] (1) Stamping and tearing the first metal part 1 to form the first arc-shaped protrusion 3;

[0029] (2) stamping and tearing the second metal piece 2 to form a second arc-shaped protrusion 4 matching the first arc-shaped protrusion;

[0030] (3) Fitting the second arc-shaped protrusion 4 of the second metal piece into the cavity formed by the first arc-shaped protrusion;

[0031] (4) riveting and extruding the first arc-shaped protrusion of the assembled first metal part and the second arc-shaped protrusion of the second metal part;

[0032] (5) During the extrusion process, the extended part of the surface of the second arc-shaped protrusion extends into the...

Abstract

The invention relates to a metal piece riveting technology. A first metal piece 1 and a second metal piece 2 which need to be riveted are included. The first metal piece 1 and the second metal piece 2are punched and torn into a first arc protrusion and a second arc protrusion, then the second arc protrusion 4 of the second metal piece is assembled in a concave cavity formed by the first arc protrusion, the first arc protrusion of the assembled first metal piece and the second arc protrusion of the second metal piece are riveted and extruded, and the first metal piece and the second metal piece are riveted together through the first arc protrusion and the second arc protrusion. Through a novel riveting method, non-rivet riveting is achieved; and compared with existing other non-rivet riveting, the strength of a riveting structure is enhanced.

Description

technical field [0001] The invention relates to a riveting process. Background technique [0002] In the existing situation, the connection between the two metal parts can be screwed, welded or riveted. The traditional riveting method is to insert rivets into the holes of two metal parts. This method of riveting has high riveting costs. Another method is to forge a bump on a metal part and rivet it into the In the hole of another metal component, although this method reduces the number of riveting components and reduces the cost, it will cause the defect of unstable connection. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the present invention provides a metal riveting process with stable connection and no increase in riveting cost. [0004] The present invention is realized through the following technical solutions: [0005] A metal riveting process, characterized in that: [0006] (1) Stamping and tearing ...
