Problems solved by technology

However, the existing products are simply riveted on a thin plate to achieve the riveting function of the product. The product cannot meet the air tightness test requirements after riveting, and the cylindrical rivet nut cannot guarantee high rotational torque requirements.
Full hexagonal rivet nuts can meet the requirements of rotational torque, but the process of opening hexagonal holes for riveted profiles is quite complicated, resulting in higher production costs

Embodiment Construction

[0025] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that all the drawings of the present invention are in simplified form and use inaccurate scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0026] Such as figure 1 and figure 2 As shown, the present invention provides a waterproof rivet nut, which includes a head flange 1 and a stem 2 integrally connected with the head flange 1 . Further, the connection between the head flange 1 and the rod 2 is provided with a chamfer 4, and the periphery of the chamfer 4 is uniformly provided with a plurality of half-rib structures 3, and the half-rib structure 3 is formed by the rod 2. The surface extends towards the bottom surface of the head flange ...

Abstract

The invention discloses a waterproof rivet nut and a production process thereof. The waterproof rivet nut comprises a heat flange and a rod portion integrally connected with the head flange. A chamferis arranged at the joint of the head flange and the rod portion, a plurality of half-rib mechanisms are evenly arranged on the periphery of the chamfer, and the half-rib mechanisms extend towards thebottom surface of the head flange from the surface of the rod portion. Since the half-rib mechanisms are added to the head flange, the waterproof rivet nut can meet the requirement for the rotating torque which is three times or above that of existing products in the same specification. The waterproof rivet nut can be used for edges of shells of new energy batteries, a traditional process of aluminum welding with low efficiency is replaced, the gas leakage preventing rivet nut with a certain air pressure value can be satisfied, and the waterproof rivet nut is matched with waterproof glue to achieve double assurance.

Description

technical field [0001] The invention relates to the field of fasteners, in particular to a waterproof rivet nut and a production process thereof. Background technique [0002] With the development of new energy technology, the traditional process of aluminum welding is still used on the aluminum battery case, and the work efficiency is low. As a riveting product, the rivet nut is provided with tension through a special riveting gun, so that the product is deformed by force and bulged to complete the riveting. However, the existing products are simply riveted on a thin plate to achieve the riveting function of the product. The product cannot meet the air tightness test requirements after riveting, and the cylindrical rivet nut cannot guarantee the high rotational torque requirement. Full hexagonal rivet nuts can meet the requirements of rotational torque, but the process of opening hexagonal holes for riveted profiles is quite complicated, resulting in higher production cost...
