Service HotlineRiveting is the most traditional way of connecting metal parts. It has the advantages of easy operation, high reliability and not easy to deform. It is widely used in the skeleton of outdoor products such as tents and camp beds. Commonly used aluminum alloy rivets use their own deformation or interference to connect the parts of the riveted parts in the riveting process. Due to cost and functional considerations, the rivet and the riveted material are often different, which is easy to occur in outdoor high humidity. Electrochemical corrosion, and the commonly used high-strength thin-walled pipes have a large shear stress on the aluminum alloy rivets at the riveting point. Under the combined action of the above two factors, it is easy to cause deformation or even breakage at the riveting point, which affects the life of outdoor products. A kind of Corrosion and shear resistant aluminium alloy rivets.
In order to achieve this purpose, the rivet nut is cold extruded from low carbon steel, the brim is cold forged, the deformed skirt is extruded in the die, and the threaded hole is extruded at the lower end of the deformed skirt. It is characterized in that it consists of a brim, a deformed skirt and a threaded hole. There are fish teeth below the brim; the outer side of the lower end of the threaded hole has a lead angle; the cross section of the thread on the inner wall of the threaded hole is an isosceles trapezoid, and the upper bottom of the trapezoid is a concave arc. Thus, the riveted object is tightly connected with the rivet nut.
Fasteners are a general term for a type of mechanical parts used to fasten two or more parts (or components) to form a whole. Among them, self-fastening fasteners are widely used in the connection of sheet metal parts due to their advantages of fast installation, high efficiency, reliability, convenient assembly, high push, pull and torsion performance, wide range of applicable materials and serialization of specifications. middle. Nuts are the most widely used type of fasteners. With the continuous change and development of the scope of use and the use environment, more demands are put forward for nuts. In particular, some occasions require the nut to have the function of waterproof sealing. The existing methods of nut sealing and waterproofing generally have the following types:
Fasteners are also divided into different types according to different uses, and new types of fasteners are developed according to the needs of special environments to meet the needs of all walks of life. The gasket combination bolt is a common fastening bolt. The combination gasket protects the surface of the connected parts from scratches, disperses the pressure on the connected parts, and has a sealing and anti-loosening effect. It is widely used. With the continuous improvement of requirements, the new zinc-aluminum coating surface treatment has gradually become the mainstream surface treatment process because it meets the environmental protection requirements, the surface is beautiful, and the corrosion resistance strength is higher than that of the zinc-nickel surface treatment.
Material broadcast Cross recessed screws are made of iron and stainless steel. Iron cross recessed screws are also called carbon steel screws. Stainless steel cross recessed screws include stainless steel SUS201 and stainless steel SUS304, and stainless steel SUS316 cross recessed screws.
