Summary of information:We have more than ten years of experience in screw industry production, the main products are: industrial aluminum T-nut...

When the iron pot is manufactured, the iron head is connected to the iron pot body through rivets, and then the pot handle is set through the iron head, and the iron head connects the pot handle and the iron pot body together. However, when the iron head is installed, the position may be inaccurate. At this time, it is necessary to remove the rivet and reinstall the iron head. At present, the removal of rivets is completely done manually, that is, workers use screwdrivers to unscrew the rivets, which is difficult to remove, wastes a lot of manpower, and has low work efficiency, thereby reducing production efficiency.

Blind hole installation type rivet is a kind of rivet for single-sided riveting. When riveting, special riveting tools, such as pull riveting, rotary riveting, etc., are required. Blind hole installation type rivets are especially suitable for riveting occasions where it is inconvenient to use ordinary rivets to be riveted from both sides. At present, blind hole type blind rivets mainly include rivet blind rivets and blind blind rivets. Most blind rivets of blind hole type contain a lock ring, through which the core rod is locked into the nail sleeve, and there is a common lock ring. Risks of falling off, insufficient clamping force, etc., and the matching relationship of each sub-part in the processing process must be strictly coordinated to ensure the best installation effect; most of the screw-type blind rivets screw the thread through the driving nut to make the nail body or pipe The body is deformed to form a bulge, and the clamping force and anti-vibration ability after installation are much stronger than that of the rivet type, but there are also many sub-parts to drive the nut, mandrel, nail body, tube body, the processing process and the matching of each sub-part When the thickness of the interlayer is different, the fractured part of the core rod is not flush with the interlayer board. For the installation parts with high flatness requirements, air tools are often required to mill them flat.

Earless retaining ring (known as Constant Section Rings abroad) is also called constant section retaining ring, because the cross section is equal, and there is no ear part protruding from the traditional stamping retaining ring, so it is called earless retaining ring. Earless retaining ring and spiral retaining ring have similarities in production, processing and use characteristics. They are both flattened and wound by steel wire. After heat treatment and surface treatment, they have good elasticity and toughness. Earless retaining ring is divided into two types: shaft use and hole use, and there are various forms of tail ends to choose from. The application of earless retaining ring is the same as that of traditional C-type retaining ring, which is widely used in hydraulic parts assembly, valves, instruments, various lock core components, needle roller bearings, pulleys, connectors, quick connectors and other mechanical assemblies.

Aiming at the shortcomings of the above-mentioned cabinets in the prior art that are assembled through hardware accessories, which affects the overall appearance, Yueluo provides a cabinet with a hidden screw-type installation structure and an assembling method thereof. The plate is fixed so that the screws can be hidden from the outside.

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.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: professional production of T-shaped nuts, GB13680 four-corner spot welding nuts, GB1096 flat key pins, single-machine tube through-hole rivets and other products, we can provide you with The right fastener solution for you.
