[0002] Riveting is divided into pull riveting, press riveting, spin riveting, self-piercing riveting, non-rivet riveting, etc. The tools required for press riveting are generally riveting presses or large-scale riveting equipment. The so-called press riveting means that during the riveting process, under external pressure, the press riveting part causes plastic deformation of the body material and is squeezed into a prefabricated groove specially provided in the structure of the riveting screw and nut, so as to realize the reliable connection of two parts.

[0003] According to the press riveting assembly process, the following standards need to be met after press riveting; there should be no phenomenon of press distortion or deviation after press riveting, and it is necessary to ensure that the thread is concentric with the corresponding hole. After press riveting, there should be no obvious deformation of protrusion or depression around the press riveting part, and there should be no obvious press marks or die marks that cannot be covered by surface treatment. After press riveting, the press riveting part should not be tilted, loose or fall off, and its firmness must be detected; its push-pull force and torque value must meet the requirements specified by the PEM of the press riveting part. After press riveting is completed, it is necessary to check whether its flatness is within the tolerance range. Content of the Utility Model

[0018] The following will describe in detail the embodiments of the technical solutions of the present utility model with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0019] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present utility model belongs.

[0020] Such as Figure 1As shown in the figure, a specific embodiment of the present utility model provides an adjustable riveting tooling for a riveting machine, which includes an upper die 100 and a lower die 200 arranged up and down; a cavity 210 for placing studs is provided in the lower die 200, and the cavity 210 penetrates through the upper end face of the lower die 200 corresponding to the position directly below the upper die 100. A depth adjustment component is provided in the cavity 210. The depth adjustment component includes a cylindrical pin 300 adapted to the cavity 210, and an adjustment pin 400 is provided below the cylindrical pin 300. A stop screw 500 threadedly adapted to the adjustment pin 400 is also provided in the cavity 210. Rotating the stop screw 500 can cause the cylindrical pin 300 to rise or fall.

[0021] As Figure 1 shown, the cavity 210 provided in the lower die 200 in this embodiment is used to place the stud structure for riveting. Through the depth adjustment component, the depth of the cavity 210 can be adjusted according to the stud and riveting specifications. By rotating the stop screw 500, the cylindrical pin 300 is raised or lowered to achieve the purpose of adjusting the depth of the cavity 210, thereby providing an economical riveting solution for studs and nuts with multiple varieties and small batches. When this device is in use, the device is installed at the riveting position of the riveting machine. The upper die 100 is pushed by the riveting machine, and the plate 700 to be riveted is placed above the lower die 200. Pressure is applied to the plate 700, nut and stud through the upper die 100 to achieve the positioning and riveting of the stud, nut and plate 700.

[0022] As Figure 1 shown, in order to avoid deformation of the plate 700, a buffer film 600 arranged around the opening of the cavity 210 is provided at the upper end of the lower die 200 in this embodiment, and the buffer film 600 is an anti-indentation protective film. In this way, the buffer film 600 can deform after being pressed, so as to offset the deformation generated by the plate 700 during the riveting process; the deformation generated by the plate 700 under pressure can be shaped by the force generated by the deformation of the buffer film 600, overcoming the problem of deformation of the plate 700 after riveting.

[0023] As Figure 1 shown, in order to improve the modularity of this device for easy disassembly and assembly, the lower die 200 in this embodiment includes a base 220 and a quick-release block 230 arranged up and down. A plurality of fixing bolts 240 fixed to the quick-release block 230 are provided on the base 220 corresponding to the outside of the cavity 210. The two-stage assembly structure is convenient for assembly according to the riveting requirements. The split design enables timely replacement even if some parts are damaged, which can effectively reduce the overall time consumption; it is convenient for technicians to quickly replace the tooling. In production applications, the upper die 100 and the lower die 200 are made of cold work die steel and have high structural strength.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
