The circlip extrusion and positioning mechanism includes a vertically installed circlip sleeve rod and a linear module controlled by a positioning motor; a plurality of circlips to be installed are sleeved on the surface of the circlip sleeve rod; the surface of the linear module can be Mobile installation quick clamp; the clamping mouth of the quick clamp is a tight top plate; the tight top plate is in contact with the upper circlip and moves up and down with the up and down movement of the circlip sleeve;

The head of the traditional screw is located outside the threaded hole and occupies a large space, which is not suitable for occasions with small space, nor is it suitable for occasions where the outer surface of the component is a working surface. For example, in the field of electronic products, or when connecting the shaft and the shaft sleeve, the machine screw with a fully threaded structure on the outer surface is widely used.

In the prior art, the earliest rivets were small pegs made of wood or bone, and the earliest metal deformations were probably the ancestors of the rivets we know today. Without a doubt, they are the oldest known method of metal joining, dating back as far as the earliest use of malleable metals, for example: the Bronze Age Egyptians used rivets to attach six wooden sectors to the outer lines of a slotted wheel Riveted and fastened together. After the Greeks successfully cast large statues in bronze, they then used rivets to rive the parts together. With the progress of the times, there are more and more types of rivets, but traditional rivets have connection strength. Insufficient problem, so a new rivet is needed to solve the above problem.

Before the special vehicle is refitted, the chassis and the car frame should be reinforced again, and the fastened part of the rivets should be disassembled before the car frame is reinforced.

If you are installing rivet nuts specially, you can use a grinder, use a rivet machine, if you are a non-professional, you can directly install a few, and then tap with an awl. Rivet equipment (manual or pneumatic) cannot be used in the field of fastening using hammers to pull rivet nuts. It is widely used and is mainly used in the assembly of electromechanical and light industrial products such as aviation, furniture, automobiles, instruments, machinery, and decoration. Of course, it is more common than the rivet nut, and it is often difficult to distinguish.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: bearing gaskets, brass washers, DIN125 black, GB30 white-plated screws and other products, we can provide you with suitable fastener solutions for you .
