Service HotlineRiveting nut tool is a special installation tool for riveting nut, including pneumatic riveting nut and electric riveting nut. Pneumatic riveting nut tool has the advantages of fast speed and large pulling force, but it is difficult to rotate into and unscrew the riveted nut. The rotating blade of the moving motor is frequently used or in a slightly dusty working environment, it will suddenly get stuck and not work, there is a great hidden danger of motor crash, and the torque of the air motor is small due to the limitation of the volume, although the riveting pulling force can be done to larger defects, but the volume also increases.
An anti-falling nut, comprising a lock buckle 1, a lock plate 2, a nut body 3, a lock ring 4 and a lock claw 5, the lock ring 4 and the nut body 3 are used together, the lock ring 4 is a circular ring, and the lock ring 4 is a ring. The inner diameter of the ring 4 is larger than the inner diameter of the circumscribed circle of the nut body 3, the outer diameter of the lock ring 4 is smaller than the inner diameter of the lock 1, the lock plate 2 is an arc-shaped metal plate, and the number of the lock plates 2 is greater than or equal to three. One end of the short side is connected to the nut body 3, the other end of the lock plate 2 is connected to the lock pawl 5, the lock plate 2 is inclined to the outside of the nut body 3, and the lock buckle 1 is provided at the connection end of the lock pawl 5 and the lock plate 2. The outer side of the lock buckle 1 is a concave arc.
Therefore, in order to obtain fasteners that meet the requirements, it is usually necessary to anneal the middle sections of bolts, rivets, etc. to reduce the hardness of the middle sections, while ensuring the hardness of the heads of bolts, rivets, etc. At present, the existing process adopts ultra-high frequency induction heating equipment to instantly heat the middle section and reduce the hardness. However, this process requires a lot of control, and the heating time is slightly longer, which affects the hardness of the head, and the mass production is very unstable, which is easy to cause the rivet to fail. At the same time, the cost of ultra-high frequency equipment is high and the power consumption is large, which is not conducive to mass production and energy saving. Environmental friendly.
Knurled copper nuts are mainly used for injection molding, hardware springs, special-shaped springs, craft gift springs, battery spring sheets, spring antennas, key rings, phosphor bronze spring CNC automatic lathe turning parts (copper car parts, iron car parts, aluminum car parts) , metal stamping parts, electronic hardware, iron shaft, single flower shaft, multi flower shaft, iron pin, non-standard screw and nut, connecting parts, fasteners, wire forming (metal wire business card holder, model aircraft landing gear, S hook , R-type latch, triangle buckle, D-type buckle) and other hardware products belong to the copper nut series.
Large, countersunk, and thin rivet nuts can be produced according to different die angles. Then the cold forged rivet nut is degreasing, cleaned and annealed, and then extruded and tapped and surface electroplated. Since the rivet nut is formed by cold extrusion of low carbon steel, it has high mechanical properties. Specifically, the tensile strength of M3 is 250Kg, the shear strength is 140Kg; the tensile strength of M4 is 700Kg, the shear strength is 220Kg; the tensile strength of M5 1100Kg, shear force 380Kg; M6 tensile force 1750Kg, shear force 450Kg; M8 tensile force 2650Kg, shear force 660Kg.
