Service HotlineThe earliest rivets were small pegs made of wood or bone, and the earliest metal variants may be the ancestors of what we know as rivets. They are without a doubt the oldest known method of joining metals, dating back as far as the earliest use of malleable metals, eg: Bronze Age Egyptians riveted the six wooden sectors of the outer lines of a slotted wheel with rivets Fastened together, after the Greeks had succeeded in casting large statues in bronze, the parts were riveted together with rivets.
As a commonly used data communication device, connectors are widely used in computers and TVs. Because common connectors such as D-SUB and DVI are composed of a male seat and a female seat, the iron shell of the male seat and the female seat is The corresponding position is provided with holes, the holes of the male seat are connected with rivets, and the holes of the female seat are correspondingly provided with screws for fixing. After the male seat and the female seat are connected, tighten the screws so that the male seat and the female seat are tightly connected together. When assembling on a computer or a TV, the rivet has a fixed assembly direction, and the fixation of the rivet direction is very important for assembly. However, there is no anti-rotation device on the iron shell hole connected with the rivet on the existing connector, and the rivet cannot be positioned during the assembly process, and it is easy to rotate and dislocate. production efficiency.
When using a BirminghamBirminghamrivet nut, drill a hole corresponding to the outer diameter of the BirminghamBirminghamrivet nut on the thin wall, then place the BirminghamBirminghamrivet nut on the bolt of the special rivet gun, push the handle to screw in the BirminghamBirminghamrivet nut, and put it into the drilled hole. In the workpiece, squeeze the handle, the BirminghamBirminghamrivet nut expands, and the deformed skirt bulges and deforms. At this time, the workpiece is tightened. After riveting, the handle is pulled out, the bolt is released from the BirminghamBirminghamrivet nut, and the corresponding screw is screwed into the BirminghamBirminghamrivet nut threaded hole. , forming a tight riveted body.
All-aluminum Birminghamblind rivet The body of the rivet is also made of high-quality aluminum wire, which is beautiful and durable after riveting and will never rust: Compared with ordinary Birminghamblind rivets, rivets have lower riveting strength and are suitable for connectors with relatively soft materials. . Split Stainless Steel Rivet: This rivet is a high-tension, corrosion-resistant choice. Round head rivets are mainly used in riveting occasions subject to large lateral loads, and are the most widely used. Flat cone head rivets are often used in riveting occasions with strong corrosion such as ship hulls, boiler water tanks, etc.
Some heavy equipment such as large motors, large reducers, etc., in order to facilitate the installation and adjustment of equipment and the need for maintenance space, a certain position needs to be moved during equipment installation and maintenance. Usually, a steel base or platform is set under the equipment, and the base or The platform is provided with an oblong bolt installation slot, commonly known as an oblong slot, as shown in Figure 1--Figure 4. When using common hexagon head bolts or common BirminghamT-bolts with the long circular groove in Figures 1 and 2, auxiliary fixing bolts or welding stoppers are required on the back of the long circular groove to prevent the bolt from rotating when the nut is tightened. In Fig. 3 and Fig. 4, the long circular groove itself has a clamping groove to prevent the rotation of the bolt, but this structure greatly increases the processing cost of the long circular groove.
