In this embodiment, the umbrella-shaped protrusion 21 has limiting surfaces 211 at both ends of the circumference of the rim 1. In other embodiments, the limiting surface 211 can be provided at only one end; when the umbrella-shaped protrusion 21 has two limiting surfaces 211, the anti-slip effect is better. In this embodiment, the height of the umbrella-shaped protrusion 21 is 0.2mm-0.8mm, and the length of the umbrella-shaped protrusion 21 is 0.5mm-2mm. In this embodiment, the umbrella-shaped protrusion 21 is higher than the strip-shaped protrusion 22, and the distance between the top surface of the umbrella-shaped protrusion 21 and the first surface 11 gradually decreases in the direction close to the strip-shaped protrusion 22.

[0052] The rivet in this embodiment has an umbrella-shaped protrusion 21 and an annular groove 32. After riveting, the material of the gasket 5 flows into the umbrella-shaped protrusion 21 and the annular groove 32, which can withstand a large pull-off force.

[0053] Compared with the prior art, this embodiment has the following beneficial effects:

[0054] In an exemplary embodiment, a compression riveted component includes a wheel rim 1 and a riveting platform 2, wherein the wheel rim 1 is provided with a first surface 11;

[0055] The riveting table 2 protrudes from the first surface 11, and includes an umbrella-shaped protrusion 21. The umbrella-shaped protrusion 21 is provided with a limiting surface 211 opposite to and spaced from the first surface 11. When the gasket 5 is embedded in the gap between the first surface 11 and the limiting surface 211, the upper and lower ends of the gasket 5 are respectively against the limiting surface 211 and the first surface 11, and can withstand a large pull-off force, so that the gasket 5 will not be easily detached from the riveting table 2. At the same time, when the gasket 5 is embedded in the gap between the first surface 11 and the limiting surface 211, the gasket 5 also abuts against the side wall of the umbrella-shaped protrusion 21 to prevent the gasket 5 from rotating relative to the umbrella-shaped protrusion 21, thereby achieving a large torque force, improving the connection strength, and facilitating use.

[0056] In an exemplary embodiment, there are at least two riveting platforms 2, which are arranged radially. The more the number of riveting platforms 2 is, the greater the torque is, and the greater the pull-off force that can be sustained is. The first surface 11 is also provided with an anti-torsion groove 111, which is located between two adjacent riveting platforms 2. When the gasket 5 is embedded in the anti-torsion groove 111, the gasket 5 cooperates with the groove wall of the anti-torsion groove 111 to further increase the torque.

[0057] In an exemplary embodiment, the pressure riveting piece is further provided with a clamping portion 3, which is provided with an annular clamping groove 32 suitable for inserting the gasket 5, and the annular clamping groove 32 is provided with a first clamping surface and a second clamping surface opposite to each other. When the gasket 5 is inserted into the annular clamping groove 32, the upper and lower ends of the gasket 5 are against the first clamping surface and the second clamping surface, and can withstand a greater pull-off force. The top surface of the riveting table 2 is connected to the groove wall of the annular clamping groove 32, so that part of the material of the gasket 5 flows into the annular clamping groove 32 preferentially.

[0058] In an exemplary embodiment, the riveting platform 2 further includes a strip-shaped protrusion 22 , and the top surface of the strip-shaped protrusion 22 is connected to the top surface of the umbrella-shaped protrusion 21 and the groove wall of the annular groove 32 respectively.

[0059] In an exemplary embodiment, the distance between the top surface of the umbrella-shaped protrusion 21 and the first surface 11 gradually decreases along the direction approaching the strip-shaped protrusion 22 . The design of high outside and low inside makes it easier to guide the material of the gasket 5 to flow into the annular groove 32 .

[0060] Embodiment 2

[0061] A riveting assembly includes a gasket 5 and the riveting member described in the first embodiment, wherein the gasket 5 is sleeved on the clamping portion 3 and is adapted to be embedded in the clamping slot, the gap between the first surface 11 and the limiting surface 211, and the anti-torsion groove 111. The gasket 5 also abuts against the first surface 11.

[0062] The riveting assembly can withstand a large pull-off force and achieve a large torque force, and is easy to use.

[0063] Embodiment 3

[0064] A stamping die is used to connect a gasket 5 with a rivet. The stamping die includes a first die 6 and a second die. The first die 6 is provided with an abutment surface 61, a through hole 62 and an annular convex navel 63. The through hole 62 opens at the abutment surface 61 and is suitable for being sleeved on the clamping part 3. The annular convex navel 63 is arranged around the through hole 62 and protrudes from the abutment surface 61. The abutment surface 61 and the annular convex navel 63 are suitable for stamping the gasket 5 so that the gasket 5 is embedded in the gap between the clamping groove, the first surface 11 and the limiting surface 211, and abuts against the first surface 11. The second die is suitable for supporting the rim 1 of the rivet.

[0065] During operation, the first mold 6 is above the second mold, the rim 1 of the riveted part is placed on the second mold, the first surface 11 is set upward, the gasket 5 is sleeved on the clamping portion 3 and the lower end of the gasket 5 is against the riveting platform 2, the first mold 6 moves downward, and the annular convex navel 63 squeezes the gasket 5. Since the umbrella-shaped protrusion 21 is higher than the strip protrusion 22 (outside high and inside low design), part of the material of the gasket 5 will be guided to flow to the annular clamping groove 32, so that the riveting performance of anti-pull-off is generated. When the pressure riveting reaches a certain stroke, the abutting surface 61 abuts against the gasket 5 so that the gasket 5 begins to cooperate with the riveting platform 2. After the riveting platform 2 penetrates into the gasket 5 to a certain extent, the gasket 5 material will flow to the bottom of the umbrella-shaped protrusion 21 (that is, the gap between the first surface 11 and the limiting surface 211), so that the riveting performance of pull-off and torque is generated.

[0066] During the final forming process, after riveting, the material of the gasket 5 flows to the annular groove 32, the lower end of the umbrella-shaped protrusion 21, and the anti-torsion groove 111, and the gasket 5 cooperates with the new bolt to produce riveting performance.

[0067] Of course, in other embodiments, the first mold 6 may be located below the second mold, and the positions of the corresponding rivets and gaskets 5 may also be interchanged.

[0074] Umbrella-shaped protrusion forming step: tapping the top surface of the boss 8 to deform part of the boss 8 to form an umbrella-shaped protrusion 21, and tapping out the anti-torsion groove 111 at the same time.

[0075] Finally, the thread rolling is performed to form the thread of the rod 71 , and the rod 71 is processed to form the collar 31 and the annular groove 32 .

[0076] The boss 8 is first formed, and then the umbrella-shaped protrusion 21 is formed by tapping the top surface of the boss 8. The mold only needs to move up and down to achieve this action, and there is no need to perform side core pulling and other actions, which can facilitate processing.

[0077] Forming the wheel rim 1 through three steps can reduce the possibility of damage and cracking of the wheel rim 1 compared to forming it through one step.
