Stainless Steel High Precision Customized Color Wire Threaded Inserts
Wire thread insert is a new type of internal threaded fastener, suitable for threaded connection. It is screwed into and fastened in the threaded hole of one of the connected parts to form a standard internal thread. The bolt (or screw) is then screwed into it. Also known as threaded wire sleeve, wire sleeve for short. It is a spring-like internal and external thread concentric body precisely processed with high-strength, high-precision, and smooth-surface cold-rolled diamond-shaped stainless steel wire. It is mainly used to enhance and protect the internal thread of low-strength materials. The principle is to form an elastic connection between the screw and the thread in the base, eliminate thread manufacturing errors, and improve the connection strength. The wire thread inserts are embedded in the threaded holes of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass steel, plastics, etc., and can form high-precision internal threads that meet international standards. They have high connection strength, earthquake resistance, impact resistance and wear resistance. Function, and can disperse stress to protect the thread of the base body, greatly extend the service life of the base body, and is widely used in electronic applications.
(1) The diameter of the wire thread insert in the free state is slightly larger than the diameter of the screw hole into which it is inserted. When assembling, the wire thread insert is subjected to a special wrench to make its diameter smaller and enters the threaded hole that has been tapped with a special tap. After being installed, the wire threaded sleeve produces a spring-like expansion effect, making it firmly fixed in the threaded hole, and will never be brought out with the screw out.
(2) Increase the load-bearing capacity and fatigue strength of the threaded connection: the wire threaded sleeve makes the screw and the internal threaded hole for the installation of the wire threaded sleeve form an elastic connection, thus eliminating the pitch and tooth form half-angle error between the internal and external threads. The load on each thread is evenly distributed over the specified length, thereby strengthening the internal thread and damping vibration, so the fatigue strength of the threaded connection of the parts can be improved.
(3) Wear resistance: The wire thread insert is precisely wound by extremely hard cold-rolled stainless steel wire, the spiral surface hardness can reach HRC43～50, and the mirror-like surface (the smoothness can reach 2～4μm) reduces friction and wear. , Can reduce the torque generated by friction on the screw by 90%, so that the maximum pre-tightening torque and screw tension can be obtained with the minimum screw torque to prevent the screw from loosening, so that the screws of various materials are in the best use condition.
(4) Corrosion resistance: Due to the excellent corrosion resistance of stainless steel wire threaded inserts, it can ensure its performance under a variety of materials and normal environmental conditions. The assembly of steel wire threaded inserts will not stagnate and rust.
(5) Heat resistance: The steel wire threaded sleeve can prevent the threaded connection from jamming or scratching at high temperatures.
(6) Material saving: Compared with ordinary standard internal threads, under the same strength conditions, after using wire thread inserts, in order to make the best use of the yield limit, a smaller size and higher strength screw can be selected. It can save a lot of material, reduce weight and reduce volume.
(7) The locking type wire thread insert can lock the screw in the threaded hole, and can prevent the screw from loosening and falling when subjected to vibration and impact, which has better process performance than the usual locking device. The locking wire thread insert has multiple disassembly and assembly without reducing the torque of the thread, and also has a high reusability.
