Service HotlineAt present, in the era of industrialization, rivets used in specific occasions, automobiles, and aviation industries can only rely on professional tools and equipment to complete the riveting method.
Riveting 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.
The screw is a fairly common structure in the technical field of machine parts assembly, and it mainly uses the mutual engagement characteristics of male and female threads to achieve the purpose of pressing the workpiece. At present, there are many kinds of screws on the market, and their functions are also very different. However, a stud and a rotating part by which the stud is rotated are the same basic structure.
Pre-embedded channels are often used in rail transit. There are usually U-shaped channels and C-shaped channels. There are also various widths of openings on one side. The T-bolts used in their connection are generally non-standard parts, which need to be The actual project needs to be customized, mostly for the overall stamping production, the mold cycle is long, the number of mold openings is large, and the production cost is high. Moreover, when assembling and connecting, it is sometimes found that the size of the originally designed t-bolts does not match, and it is necessary to replace t-bolts of different sizes, then it is necessary to redesign and produce non-standard t-bolts, which slows down the entire equipment. processing cycle. Customized T-bolts are often not wide enough in size range, and only a few can be selected for specific assembly and connection, which is difficult to meet the diverse requirements of the production site for bolts.
