2results about How to "Improve riveting strength" patented technology

The present disclosure relates to the technical field of riveting equipment, and provides a riveting die and a new rivet. The former comprises a riveting upper die, a riveting lower die and a riveting assembly. The riveting lower die is provided with a recessed riveting hole, and the riveting assembly is arranged in the riveting hole. The riveting assembly is provided with a containing hole for containing the rivet and an extrusion piece arranged on the inner circumferential part of the containing hole. The riveting upper die can press the rivet and the riveting piece into the riveting assembly, and the extrusion piece can be extruded towards the center of the containing hole synchronously, so that the riveting piece is at least partially wrapped around the circumferential part of the rivet. The latter can be applied to the riveting die, and comprises a rivet head and a rivet rod. The end part of the rivet rod near the circumferential wall of the rivet head is further provided with a riveting part. The riveting piece can be riveted and wrapped around the riveting part in a manner of being inclined towards the center of the rivet rod. The riveting die and the new rivet can both solve the problem that the root part of the rivet is easily inclined and affects assembly during riveting.

The utility model discloses an equipment for riveting wheel axle in plastic wheel, including the positioning assembly, the top pressure subassembly and the drive assembly of being located on the frame, through the controllable output speed and pressure of drive assembly output, make top pressure subassembly in the riveting process with controllable speed and force and press into the assembly through -hole of plastic wheel of wheel axle, namely through accurate control riveting speed and pressure, avoid tearing of the assembly through -hole edge of plastic wheel caused by instantaneous impact or excessive pressure, thereby solve the plastic hair of traditional cylinder / hydraulic cylinder high -speed impact and produce, and the one -time pass rate of product is improved significantly, and the product quality is improved.
