5results 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 application discloses an automatic riveting machine, which comprises a frame, an upper die conveying mechanism, a lower die conveying mechanism, an upper die punching mechanism and a lower die connecting mechanism. The innovation mainly lies in the lower die connecting mechanism, which comprises a lower die driving assembly, a lower die connecting part and a lower die punching part. The lower die driving assembly drives the lower die connecting part and the lower die punching part to move sequentially through a connecting driving part with a first action surface and a second action surface. During work, the lower die connecting part first bends the claw end of the claw buckle at the bending part of the punching position, and then the lower die punching part goes up to flatten the bent claw end, thereby completing a high-strength and high-reliability riveting process. The application realizes the two core actions of bending and flattening through single automatic operation, effectively simplifies the equipment structure and improves the riveting strength. The application has the beneficial effects of high riveting strength and simple equipment structure.

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.

The utility model provides a conducting ring and a motor, and belongs to the conducting ring technical field, the conducting ring comprises an annular piece, the annular piece is provided with a mounting hole and a riveting hole, the riveting hole and the mounting hole are aligned in the thickness direction of the annular piece, and the hole bottom of the riveting hole is provided with a wave-shaped indentation surface; in the corresponding mounting hole and riveting hole, a solid part between the wavy indentation surface and the hole wall of the mounting hole is set as a flow deformation part; one part of the conductive fiber bundle is arranged in the mounting hole, the other part of the conductive fiber bundle extends out of one port of the mounting hole, and the hole wall of the mounting hole tightly hoops the conductive fiber bundle so that the conductive fiber bundle and the mounting hole can be riveted. The conductive ring has the beneficial effects that the structural design of the conductive ring is very ingenious, the riveting hole can be fully extruded, and the wavy indentation surface can enable the flow deformation part to generate more reasonable and accurate deformation flow, so that the hole wall of the mounting hole completely hoops a conductive fiber bundle, and the service life of the conductive fiber bundle is prolonged. And the riveting strength and the conductivity between the conductive fiber bundle and the annular piece are improved.

The utility model relates to the technical field of stamping, and discloses a stamping device for pressing and riveting a high boss, which comprises a base and a vertically sliding stamping plate. A stamping groove is formed in the base, a workpiece is arranged in the stamping groove, a stamping block is arranged at the bottom of the stamping plate, the stamping block and the stamping groove are matched with each other to conduct stamping operation on the workpiece, four rivet pressing holes are formed in the base, four rivet pressing blocks are installed at the bottom of the stamping plate, and the rivet pressing blocks correspond to the rivet pressing holes. According to the utility model, the stamping and press riveting processes are synchronously carried out, so that the waiting time of traditional step-by-step processing is reduced, the processing cycle of a single product is shortened, synchronous press riveting can be carried out by utilizing the ductility of materials in the stamping plastic deformation process, the riveting strength is improved, and the problem of cracks or stress concentration possibly generated by traditional cold riveting is avoided; and the integrally formed high boss can be directly used as a rivet, so that the process of additionally mounting a fastener is omitted, and the product assembly process is further simplified.
