What is the screw sliding tooth processing method of Huizhou screw factory?

During hardware research and keyboard cleaning, the machine often needs to be disassembled. When there are no special tools or lack of experience, screw twisting (also called sliding wire) often occurs. Therefore, todayHuizhou Screw FactorySome remedies will be presented.

(1) Put things on the screwdriver head, such as double-sided tape, non-woven fabric, etc. If there are no conditions, you can also use paper, which will increase friction.

(2) Inject a small amount of 502 glue into the screw hole, and then screw in the screw. After the glue solidifies, use needle-nose pliers to unscrew the screw (because you don't use a screwdriver, you are worried that the screw will slip off), and wait for the glue to completely harden.

(3) If the nut is exposed, use needle-nose pliers to tighten the nut, and then unscrew the screw. You can also cut off the nut, disassemble the shell, and then dispose of it.

(4) Generally speaking, the screw of the mobile phone is metal and the shell is plastic. You can insert a sharp soldering iron into the nut, heat the metal screw to melt the plastic around the screw, and then clamp it with sharp pliers. Gently pull it out. You can also press down the screw by about 1mm (be careful not to penetrate the housing) to solve the problem of loose screws.

(5) It is really difficult to repair such a small screw. In the past, a small electric drill was used to drill a small hole in the middle of the twisted screw, and then a reverse tap was used to screw in the bicycle screw, and then you can unscrew it.

(6) Use the countersunk screw of the electric drill to drill it out.

(7) Burn the screwdriver head of Huizhou Screw Factory red on the gas stove, then quickly push it onto the screw, wait about 5 seconds, and then it can be screwed out.

(9) Grind the blade of the flat screwdriver and start tightening.

(10) The molten solder hangs on the torch head. After the screwdriver and screw are aligned, spot weld the solder, cool and loosen.

(11) Then knock off the gong cap with a drill. Use the reverse thread principle to drill out the remaining screws (you can use the special drill bit for broken head screws-broken head screw extraction device).

(12) The maintenance personnel solved this problem with a large screwdriver, and the purpose of the screwdriver should be changed from small to large. Of course, you don't want to change the screwdriver frequently, but it is easy to spend too much at the beginning, and it is easy to spend too little at the beginning. The big screwdriver comes to the stage after the screws are used up.

(13) Use small pointed-nose pliers to help you pull it out.

(14) Use a soldering iron to burn the solder on the sliding screw, stick the screwdriver of Huizhou Screw Factory on it, and wait for the solder to dry before turning.

(15) Use a knife to carve repeatedly on the screw until the Phillips screw is carved into a slotted screw, and then it can be removed. This takes about 10 minutes.
