Service HotlineThe core rivet is a new type of riveting fastener that is very convenient for riveting. It can show its unique advantages in a relatively small space or in an environment where there is no rivet gun or a rivet gun cannot be used. Two or more connected parts can be riveted successfully by hitting the mandrel on one side with a hammer or other utensils. Core rivets can be divided into oblate head core rivets and countersunk head core rivets according to the shape of the brim of the nail cap. According to different material combinations, they can be divided into all aluminum core rivets, aluminum steel core rivets, and all stainless steel core rivets. Rivets, steel rivets, aluminum stainless steel rivets, plastic rivets, etc. Core rivets do not have to be riveted with manual riveting guns or pneumatic riveting guns like blind rivets. They have better riveting and convenience, and can be widely used in the riveting of various connected parts.
If the above-mentioned nuts and screws are used as a kind of fasteners that can prevent others from being disassembled, such as when installing iron doors-steel windows, people usually tighten the nuts first, and then use a welding machine to weld the nuts and screws. To prevent the nut from loosening, it may be necessary to use a tool to mill the threads on the screw. It can be seen that this approach is very inconvenient.
At present, the commonly used shaft retaining rings in the market usually include elastic retaining rings and screw locking retaining rings, but they all require tools to be installed and disassembled, which is relatively inconvenient to use.
Blind rivets are a type of flying rivets for single-sided riveting, but they must be riveted manually, electrically, and automatically using special tools. This type of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets and must be riveted from both sides, so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products.
Ordinary open rivet is a kind of product in rivet. It is riveted to the workpiece by expanding the rivet body after the big end of the mandrel is pulled. After the traditional rivet is riveted, the operator will cut the mandrel short, the mandrel does not work, and the workpiece is riveted by the material strength of the rivet body itself. After the mandrel is pulled, the middle of the rivet body becomes a cavity, and the mandrel shears The distance of the segments is relatively random. The random shearing determines the length of the cavity of the riveting body, and the length of the cavity determines the tensile and shear strength of the riveting body. The volume of the cavity is large, the tensile and shear strength is low, and the cavity is small. , the tensile and shear strength is slightly improved, so the breaking point of the rivet can completely affect the use effect of the rivet.
