The toothed flakes have good elasticity and can be directly manually pressed and installed in the round holes of the interference assembly. The toothed flakes can be installed according to the actual thickness and size. It can be fixed by self-adjustment. The design of the inverted tooth type is that the rivet is firmly fixed to the installation surface after installation, and it is not easy to be pulled out. It is suitable for fixing between soft materials such as foam, wood, rubber, and automobile interiors. Plastic tree rivets have excellent insulation, fire resistance, non-magnetic, heat insulation, light weight, high temperature resistance, high strength, corrosion resistance, and are widely used in various industrial fields.
Yueluo Company adopts the following technical solutions: fasteners for preventing nuts from falling off, including bolts and nuts, the nuts are provided with screw holes, the screw holes are provided with internal threads, the bolts are provided with M grooves along its axial direction, M ≥1; There is an arc-shaped notch on the screw hole of the nut, and there are N V-shaped tooth grooves along the axial direction of the nut in the arc-shaped notch, N≥2; a locking strip is placed in the groove, and the locking The bar includes a locking bar body and a V-shaped locking tooth, the width of the locking bar body is the same as the width of the groove, the V-shaped locking tooth is located on one side of the locking bar body, and the V-shaped locking tooth is engaged with the V-shaped locking tooth.
When the iron pot is manufactured, the iron head is connected to the iron pot body through rivets, and then the pot handle is set through the iron head, and the iron head connects the pot handle and the iron pot body together. However, when the iron head is installed, the position may be inaccurate. At this time, it is necessary to remove the rivet and reinstall the iron head. At present, the removal of rivets is completely done manually, that is, workers use screwdrivers to unscrew the rivets, which is difficult to remove, wastes a lot of manpower, and has low work efficiency, thereby reducing production efficiency.
The earliest rivets were small pegs made of wood or bone, and the earliest metal variants may be the ancestors of what we know as rivets. They are without a doubt the oldest known method of joining metals, dating back as far as the earliest use of malleable metals, eg: Bronze Age Egyptians riveted the six wooden sectors of the outer lines of a slotted wheel with rivets Fastened together, after the Greeks had succeeded in casting large statues in bronze, the parts were riveted together with rivets.
In the past production, gaskets were generally obtained from two channels: first, standard gaskets were mostly purchased from the market, and the cost was high; non-standard gaskets, due to the small demand, required separate tooling and molds, which were expensive and long production cycle. It is difficult to purchase; Second, the plate is purchased by the enterprise, and then the washer is formed by the automatic cutting machine. Because the cut nodules and cut marks produced by flame cutting do not meet the requirements for use, the inner and outer diameters need to be reserved 2 ～3mm machining allowance, and then finish the outer diameter and inner diameter by lathe.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: national standard PortlandPortlandstainless steel screws, standard carbon steel screws, metric American nylon locking nuts, JB4763 bolts and other products, we can provide you with suitable fastening products piece solution.
