Ring groove rivets are fasteners composed of a rivet shank and a collar. It combines high-strength bolts and rivets. Unlike traditional threaded fasteners, the locking between the nail shank and the collar is by compressing the collar. The deformation is achieved on the ring groove.

Pay attention to the characteristics of ring groove rivets. Firstly, installation is more convenient than ordinary rivets or bolts, without the use of stop washers, cotter pins and special nuts; secondly, it is difficult to disassemble and use as an installation fixture. Combined with these characteristics, ring groove rivets are mainly used Used in vibrating screen industries such as subways, high-speed railways, railways, and mines, washing equipment, etc.

Ring groove rivets, to put it bluntly, during the riveting process, the nail rod needs to be pulled by the ring groove rivet gun to keep it motionless. Therefore, ring groove rivets will have a long nail tail, which is in contact with the ring groove rivet during the installation process. The gun head contacts, and the nail tail is pulled off after installation.

As I just said, ring groove rivets are not easy to remove. Since the locking method is to press the collar against the ring groove and deform it, cutting the collar is an effective way to destroy the collar.

Suddenly I remembered a special advantage of ring-groove rivets. Of course, this is compared to threaded fasteners, that is, its specially designed sandwich area. We all know that before installing bolts, we usually need to measure the thickness of the hole to determine The interlayer length of the bolt. However, there are always some special circumstances. Due to the influence of plate tolerances or other reasons, the interlayer thickness of the fastener jumps to the next range selected in the design, which may cause some trouble for assembly. The root of all this is because the interlayer interval of threaded fasteners is a continuous interval, which means that the thickness of each interlayer is connected end to end, which creates an either\/or phenomenon.

Of course, a special advantage of ring-groove rivets suddenly arises, that is, ring-groove rivets have a special advantage compared to threaded fasteners. As we all know, it is common to measure the thickness of the hole before installing the bolt, to determine the length of the bolt layer. However, due to the influence of plate tolerances or other reasons, the thickness of the clamping layer in the next section of the structure will always jump, which may cause assembly problems. This is because of the layer of threaded fasteners The flow section is a continuous section, that is, a continuous section. The thickness of each layer is connected from one side to the other. Although the annular groove laminar flow sections are designed in series, the overlapping area is highlighted between 2 adjacent sections, which is similar to To increase tolerance range and reduce assembly problems.
