Service HotlineThere are many types of rivets, including dome head, flat head, blind rivet and so on. When riveting parts, they will have uneven force and affect the quality of riveting. Some rivet caps are too thin to easily affect the quality of riveting. Some rivets have poor tightness of riveted parts when riveting. Therefore, both the structure of the rivet and the tightness of the riveting need to be considered, so as to enhance the quality of the rivet fastening.
In order to solve the above-mentioned technical problems, a technical scheme adopted by Guangdong Yueluo Hardware Industry Co., Ltd. is: a rivet capable of selecting a breaking point is provided, comprising a nail body and a mandrel, and the mandrel is sequentially provided with from the head to the tail. Hemispherical head, cone and cylinder, the cones are provided with at least three, the mandrel penetrates into the nail body from the bottom of the nail body, and then goes out from the head of the nail body, the hemispherical head and the cylinder Exposed on the bottom of the nail body and the outside of the head, the cones are all arranged inside the nail body.
At present, in the riveting of automobile and motor car parts, especially the parts that have vibration and need to move frequently, such as automobile steering gear, ordinary rivets and double-drum rivets are mostly used for riveting. Due to the limitations of the structure of these two products After riveting, the product has the defect of insufficient strength and easy to loosen and fall off, and it cannot be disassembled and can only be used once, thus affecting the quality and performance of the riveted product.
Screw (English a screw) refers to the parts used in construction machinery. It is a kind of threaded parts with sharp ends such as nails, small cylindrical or conical metal rods, with grooved or dimpled heads, and used alone. . The detection of the screw should start from the wire of the screw. The quality of the precision screw is directly related to the wire that produces the screw. A good screw wire will open the screws more beautifully. What screw head burst, what thread is bad. Good screw wires generally do not find this situation.
The grooved embedded parts are pre-embedded in concrete, and then placed in the groove with T-bolts. After adjusting the fixed position, the fixed object is locked with a nut to achieve the fixing effect. When the grooved embedded parts are embedded vertically in the concrete or at a certain angle to the horizontal line, the T-bolts are likely to move in position before they are tightened. In particular, when fixing heavy equipment, multiple T-bolts are required, and multiple groups of workers are required to help and positioning is difficult, and the installation process is complicated.
