Whether it is a basket screw or a chuck screw, as long as it is a hardware rigging type screw, it is inevitable that oxidation rust will be difficult to disassemble during use. However, in order to facilitate future maintenance or assembly, we must perform disassembly and maintenance. If you take some simple methods to burn, cut, oil, etc., it is likely to damage the accessories. Below, Qingdao Hong Tengda Machinery Manufacturing Co., Ltd. came to discuss with you the problem of disassembly of rusty screws.
The rusting screw is disassembled in one way. Loose agent; the loosening agent is generally used in the case where the rust is not very serious. Because of the more serious rusting screw, the loosening agent hardly penetrates into the inside of the screw, thereby preventing the internal chemical reaction from proceeding. Therefore, it is necessary to wait until the penetration of the loosening agent completely completes the reaction before the operation can be performed. This period of time is very inconvenient for those who are catching up with the construction cycle. Therefore, this choice also has drawbacks.
Corroded screw removal method 2, fire, sawing; in many large construction sites, we can often see that many screw nuts that are corroded and corroded, must be paid attention to corrosion when they are burned with gas cutting tools and then fired. Whether the object remains flammable, or avoid damage to internal equipment when burning gas. Saw cutting is also a common method of disassembly. In the sawing process, the crusher is usually used. The cutting machine is broken and cut in a violent manner. It cannot be cut in a narrow position or in an internal part.
Corrugated screw removal method 3, screw broken; the whole crushing of the screw with the crusher is also a method we often use, but if you encounter different types and types of screws, then the crusher is difficult to work because of the special parts and There are more and more special machining parts, and the internal and external structures are also complicated, so breaking is not a good choice.
In addition to the traditional methods above, there are some high-tech products. The high-frequency electromagnetic field rapidly warms the metal to 300~500 degrees Celsius, and the screw can be rapidly expanded in a short time. After the surrounding gap is increased, it can be unloaded by other methods. This method should pay attention to the use of rubber and other products, because rubber and plastic products will deform after preheating, and should be cautious if it causes adverse consequences.
