1. What is a wire thread insert? r? Wire thread insert is a spiral coil precisely formed from cold-rolled rhombus wire. It is a concentric body with internal and external threads, and one end has a radially bent installation handle.
Wire thread inserts (also known as wire thread inserts and thread sheaths) are a new type of internal and external threaded fasteners that can be embedded in metal
or non-metallic materials and cut into high-strength, wear-resistant, and interactive Replaceable standard threads can also be used to repair worn or damaged internal threads
holes.
2r? What is the principle of using wire thread insert?
The diameter of the wire sleeve in the free state is slightly larger than the internal thread it is installed into. During the assembly process, the torque added by the installation tool to the installation handle causes the diameter of the guide ring to shrink
. Thus, it is introduced into the internal threaded hole tapped in advance with a special tap for wire thread inserts
3. What are the advantages of using wire thread inserts? The advantages of using wire thread inserts are as follows:
◆ Extended service life: Since the wire thread inserts are made of stainless steel and have higher hardness, the thread life of the softer base parts can be increased by dozens to several times
It increases its strength a hundred times and avoids tripping and random buckling.
◆ Increase connection strength: It can be used for soft low-strength alloy materials such as aluminum and magnesium, wood, plastic, rubber and other easily deformed low-strength materials to avoid slipping
wires and misaligned teeth.
◆ Increase the stress surface: It can be used for thin parts that require strong connections but cannot increase the diameter of the screw hole.
◆ Improve connection conditions and increase the load-bearing capacity and fatigue resistance of threaded connections: using wire thread sleeves can eliminate the pitch and tooth profile deviation between the screw and the screw hole, reducing the load Evenly distributed, thereby improving the load-bearing capacity and fatigue resistance of the threaded connection. It can be used to fasten the connection and fastening of hard, brittle and fragile materials such as ceramic bakelite
glass. Effectively prevent chipping.
◆ Anti-rust: The characteristics of the wire thread insert material itself and its extremely smooth surface will prevent the mating substrate from rusting when used in harsh environments such as moisture and corrosion, thus avoiding the risk of rust. The loss of replacing the expensive base body due to the threaded holes being rusty and unable to be disassembled by hand.
◆ Wear-resistant, heat-resistant and corrosion-resistant: Due to the extremely high surface finish of the wire thread insert, it can effectively reduce the friction between the internal and external threads. The material itself
is also resistant to high temperatures. Corrosion resistant properties. It can be used in parts that are frequently disassembled and installed and screw holes that are frequently rotated to extend their service life
◆ Anti-seismic and anti-loosening: The special structure of the locking screw sleeve can lock the screw in the screw hole without loosening
in strong vibration and impact environments. The locking performance is better than other locking devices. It can be used in occasions such as precision instrumentation, valuable power equipment, aerospace and military equipment
that require a high insurance factor.
◆ Easy to repair: When thread processing errors occur or damaged internal threads are repaired, the wire thread sleeve can be used to bring the base body back to life
and the original screws can be used, which is fast and cost-effective. economy. A simple example, such as diesel engine body
Textile parts, various aluminum machine parts, lathe tool tables, etc. will be scrapped because a screw hole is damaged. As long as it is re-tapped and the thread sleeve is installed, it will be scrapped
The item is brought back to life.
