Kako to deal with hardware furniture vijci to cannot be stegnuto

Vijci i vijci are a common type of fixing in daily life. Normally, they play a pričvršćivanje ulog. Of course, we hope that they will be be tighter, this will also add some trouble to the subsequent maintenance technicians, especially When the vij is seriously zahrđao, it je teško to odvrnuto it izravno, i it je more vjerojatno to break or slip. At this time, people are like the eight besmrtnici crossing the sea, and various methods appear, such as knocking, dripping, burning, flushing, etc. Zavarivanje, namakanje, sjeckanje, rezanje, itd.

The first thing that ordinary people think of is "knocking". Most of the time, when they can't unscrew something, they just hammer twice, sometimes to vent their emotions. Without further ado, let's get to the point.
1. Kada kucanje jako korodirani vijci i oni ne mogu biti zategnuti, do ne upotreba pretjerana sila to prevent the rubovi od klizanje, breaking the the vijci or breaking the ključ. In this case, you can use a hammer or other instrument to gent tap the handle of the ključ, and use vibracije to connect the hrđe to olabavi te threads, and then you can twist.
2. For screws that are not seriously rusted, you can first try soaking them with dripping water. If they still cannot be unscrewed, drip a little engine oil or vegetable oil along the gaps between the screws and nuts. Use wire cutters and a wrench to unscrew them easily. (Using oil is ineffective for severely rusted screws and will affect disassembly) There is also a special chemical agent "drop screw" that acts on the contact surface between the screw and the tool to increase the friction of the contact to achieve increased friction. The effect of twisting force. After use, it can increase the friction force by 500 times, which is more than enough for ordinary dead screws. If it is used with complementary uses such as rust remover and lubricant, the effect will be more obvious.
3. Use a gas zavarivanje plamen to potpuno roštilj te vijci i matice, i onda kap motor ulje on the crveno-vruće vijci or zategni njih izravno. Ovo je jer the vij skuplja kada se zagrijeno, povećanje praznina. After the oil kapljice, te vijka skuplja brzo when hlađeno, further inass the gap between the screw štap and the nut. The Knight can be unscrewed after the the oil in. (Napomena to vijci s plastika dijelovi obližnji treba biti korišten s oprez, i izgorjeli vijci are ne prikladni za ponovna uporaba)
4. If the flat opening or cross opening on the top of some screws is deformed and cannot be removed with a screwdriver, wrench, or wire cutter, the impact method can be used. First, use a hammer or a chopping knife to impact a V-shaped groove on the vertical surface of the top of the screw. Then adjust the angle of the chopping knife and strike in the direction of the thread. After loosening the screw for a while, you can use pliers to unscrew the screw.
5. Soaking: Soak the screws that need to be unscrewed in used engine oil for a period of time. The oil will penetrate into the screw teeth, so that they can be screwed. It just takes a long time to fit the screws that are not needed immediately.
6. Elektromagnetska zavojnica indukcija grijanje
A grijanje metoda to pretvara električna energija into magnetska energija to induce eddy struje on the surface of the heated steel body. The above method of burning can be used anywhere, and is more appropriateable for narrow spaces. It can točno parcija toplina, so areas other than the heated object can still maintain the original temperature, &the impact on other parts. The Heated Object , it will shrink and loosen% 2c izrada it easy to rastavljanje ili instalacija.
7. Zavarivanje Ovo je uglavnom korišteno to deal with the deformacija of the nut, the vij slip angle, and the flat or cross deformacija at the top of the vijka. To is, put it on the nut and vijak, i zavariva a A Nut on The Top to facilitate The Operation of The Tool.
The above are all relativno less destruktiv metode. The follow is a destruktiv solution.
8. Chopping is mostly used to deal with nuts, and the nuts that cannot be twisted are chopped into pieces to separate them from the screw.
9. Use an electric bušilica to bušilica a rupa te vij glava to to cannot be vijčano, i onda use a kontra-navoj tapping alat to vijak it. Ovo je a a uobičajena metoda to deal with the slip angle of the internal angle vijak.
10. Nut breaker The nut breaker consists of a hydraulic cylinder, a cutter and a tool holder. It adopts a single-acting return hydraulic cylinder method to cut the nut into two halves at one time without damaging the screw and can continue to be used.
11. Rezanje Upotreba a mala rezanje stroj to rez i prekid matice to ne može biti zategnuto. Or use an kisik rezač to burn the nut or vijak into rastaljeno željezo i puhati it isključeno.
