Description

Technical Field

[0001] The utility model relates to the field of display back panel processing equipment, in particular to a rivet flanging slider riveting structure for a display back panel. Background Art

[0002] In displays, especially commercial displays, hook holes or hook nuts are generally provided. In actual processing, the hole parts or nut parts are generally combined with the back plate by riveting, so as to ensure the stability of the combination. However, in actual processing, the existing pull rivet structure can be used to achieve stable riveting fixation. However, for rivets with a flange structure, the use of a pull rivet structure may cause the rivet to get stuck or the flange to be damaged, and it is also troublesome to remove the rivet. Utility Model Content

[0003] The main purpose of the utility model is to provide a rivet flanging slider riveting structure for a display back plate, aiming to adopt the slider riveting structure to achieve the combination of the rivet and the back plate, while facilitating riveting.

[0006] The upper die is provided with a rivet column, which can extend into the positioning hole. When the first pressure riveting seat and the second pressure riveting seat are molded together, the first pressing groove and the second pressing groove are located at the outer periphery of the rivet column.

[0007] In actual processing of the technical solution of the utility model, the rivet is placed in the rivet cap (wherein the rivet cap is integrally formed with the back plate and is provided with a flange), and when the upper mold and the lower mold are closed, the rivet column extends into the rivet or positions the rivet (extends into the nut when it is a nut, and limits the rivet when it is a rivet); then the first pressure riveting seat and the second pressure riveting seat are closed together, thereby applying pressure to the outside of the rivet cap, thereby fixing the rivet cap and the rivet to each other, and at the same time will not affect the flange structure, that is, applying pressure to the periphery of the rivet cap, thereby achieving the pressing of the rivet and the rivet cap; and when demolding, the first pressure riveting seat and the second pressure riveting seat are tilted outward to open the mold, and the mold opening is smooth, and they will not affect each other.
