In recent years, the use of brushed rivets has gradually become popular in the construction industry, especially after the emergence of 12.7mm diameter brushed rivets, which provide a more convenient connection method for the main structure. The tensile strength can reach more than 30,000 Newtons, and the shear strength can exceed 40,000 Newtons. .Whether it is a light steel structure or a heavy steel frame structure, wire drawing rivets of different sizes can give full play to the advantages of wide riveting range, high work efficiency, and high structural strength, helping to improve the reliability of connections and speed up production progress.

Internal locking rivets are very similar to external locking rivets in appearance, and their functions and strengths are basically the same. These two products are slightly different in use. External locking rivets require a special gun head, which can form a visible external lock after riveting. , for easy inspection. Internal locking wire rivets can be applied to standard gun tips to provide internal locking protection.

Brushed rivets are one of the most important products among structural core blind rivets, with dual locking and sealing functions. After riveting, the core lock forms high tensile and shear strength in the rivet body. The rivet body material of brushed rivets is aluminum , iron, stainless steel, etc. The products are mainly used in the aviation manufacturing industry. In my country, pull rivets are also called cup-shaped blind rivets, including internal locking pull rivets and external locking pull rivets. Drawn rivets are also called cup-shaped self-pull rivets, which are The structure is a self-pull rivet. After riveting, the broken part of the nail core will be transferred to the groove of the rivet body to lock the nail core. On the surface, there is not much difference between internal locking wire drawing rivets and external locking wire drawing rivets, and their mechanical properties are roughly the same. , mainly due to the different locking structures after riveting. Generally speaking, internal locking wire rivets can be used with conventional rivet guns, while external locking wire rivets require a corresponding rivet gun.

The brushed rivet is a high-strength structural rivet with high mechanical properties and certain waterproof sealing performance. The head of the brushed rivet adopts a cup-shaped design, which promotes the deformation ability of the nail head to shrink freely. Therefore, when riveting, the nail core is On the one hand, it expands the pipe cap, and on the other hand, it forms a mechanical interlock with the pipe cap, and the remaining nail cores are automatically locked in the expanded pipe cap. Brushed rivets have a wide range of riveting, strong clamping force on the riveted parts, sealing performance and shock-proof function Good, extremely high mechanical strength. After the wire drawing self-pull rivet is riveted, the broken part of the nail core will be transferred into the groove of the rivet body, forming a "mechanical external lock" to lock the nail core. High tensile and shear capacity; earthquake resistance ; The lock cylinder has strong ability; the visible lock is easy to inspect; and the sealing performance is good.
