Service Hotlinerivet is a nail-shaped object used to join two parts or components with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal, commonly used are R-type rivets, fan rivets, blind rivets, blind rivets, tree rivets, semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, hollow rivets Rivets, these usually use their own deformation to connect the riveted parts. Generally less than 8 mm with cold riveting, larger than this size with hot riveting. But there are exceptions. For example, the nameplate on some locks is riveted by the interference between the rivet and the lock body hole.
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.
Copper nuts, also known as embedded nuts and inlaid copper nuts or plastic embedded nuts, are divided into hot-melt copper nuts, hot-pressed copper nuts, embedded copper nuts and ultrasonic copper nuts according to different methods of use. This product is widely used in mobile phones. Shell / Pen meter shell / injection part / insert of plastic part, used as an internal thread. Generally embossed on the outer circle. To prevent sliding. Stainless Steel Nuts Hexagon Nuts (GB6170/DIN934), Thin Nuts (GB6172/DIN439), Heavy Nuts (Metric, US), Nylon Lock Nuts (DIN985-DIN982 Thick), All Metal Lock Nuts (DIN980M), Cap Nuts (DIN1587), Flange Nuts (GB6177/DIN6923), Flange Nuts Nylon Lock Nuts (DIN6926), Square Weld Nuts (DIN928), Hex Weld Nuts (DIN929), Butterfly Caps (GB62, DIN315, American), K cap, etc. Specifications: M1.6-M64
At present, the locking washer is widely used in the upper wheel side locking of passenger cars. During assembly, the locking washer is bent perpendicular to the thread of the axle pipe, so as to prevent the protrusion from passing through the gap between the two tooth profiles of the thread and ensure the locking The stop gasket is always in the groove of the shaft tube and cannot be rotated to achieve the purpose of locking. This method is relatively simple and is currently used more;
self-locking nut is a nut that can self-lock by friction. The general nut will loosen itself due to vibration and other reasons during use. In order to prevent this phenomenon, the self-locking nut was invented. The main functions of self-locking nuts are anti-loose and anti-vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque type lock nuts (see GB/T3098.9-2002 national standard).
