Nowadays, fasteners are used for fastening on machinery, equipment, vehicles and railways. That is to say, in many applications, fasteners are indispensable for connecting fastening parts, and the fastener manufacturers are annoyed by "how to eliminate What are the symptoms of fastener rust lock?" This is also a common problem in our daily life, but many people do not know how to deal with it flexibly. Here, we share the five parts about the rust lock of the fasteners. song.
fastener
First, "shock": For those screw-studded stainless steel fasteners that are rust-locked, we can use a hammer to strike the wrench with a proper force to vibrate the fasteners, so that the locking screws can be made It was easily unscrewed.
2. “Knockingâ€: Tap the rust-locked stainless steel stud with the edge of the square hammer to loosen the rusted fastener. For the strength of the tapping, it can be determined according to the specific conditions of the mounting position of the nut. For example, the nut on the bolts on both sides of the bicycle pedal can be reasonably grasped according to the metal structure of the pedal, the thickness of the metal, and the like. The strength. If this does not solve the problem, we can use a hammer to twist the nut counterclockwise, so that the fastener can be easily removed.
Third, "burning": This method is suitable for use in the case of rust lock more serious, if the above magic can not solve the problem, we can use the gas welding flame to burn the rusted nut, after the burning is completed Lubricate the threads of the red-burned fasteners so that the rust-locked fasteners can be easily removed. (The principle of this method is the principle of "thermal expansion and contraction". It should be noted that some plastics and other devices that are easily melted by heat are prohibited from using this magic weapon.)
Fourth, "rush": Because of the rust is more serious, the fasteners that cause corrosion on the top of the screw, we can use this method. Simply use the hammer and the screwdriver to make a vertical impact on the top of the screw. The purpose is to form a v-shaped groove and then impact the fastener in the direction in which the screw is screwed out until it is loose. Finally, we can use The pliers were easily removed. (This method is also suitable for use when the "one" or "ten" screws appear in the slip).
5. “Weldingâ€: This magic weapon is suitable for use in cases where the rust is severe and the screw is broken during disassembly. In response to this situation, we can use electric welding to weld a suitable length of iron on the twisted screw, and then combine it with the above magic weapon. The cross-sectional size of the welded iron block can be determined according to the diameter of the stainless steel screw.
Reminder: When there is a phenomenon of rust lock, it is necessary to use the above five methods to disassemble the fasteners scientifically and reasonably. Otherwise, the hexagonal corners of the screws will be screwed, the screws will be broken, and the wrench will be screwed. And so on.
