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] like 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 ou...

Abstract

The present invention relates to a metal piece riveting process, including the first metal piece 1 and the second metal piece 2 that need to be riveted. The second arc-shaped protrusion assembles the second arc-shaped protrusion 4 of the second metal piece in the concave cavity formed by the first arc-shaped protrusion, and the first arc-shaped protrusion and the assembled first metal piece The second arc-shaped protrusion of the second metal part is riveted and extruded, and the first metal part and the second metal part are riveted together through the first arc-shaped protrusion and the second arc-shaped protrusion. The invention realizes rivetless riveting through a new riveting method, and compared with other existing rivetless riveting, the strength of the 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 ...
