The bit of the tap and the forest are broken in the hole, how to do it? Let’s take a look at these 25 methods!
1. Fill in lubrication oil, use a pointed hair pin or a chopper to knock them out slowly on the surface of the fracture, and sometimes transform the iron into a cut (the most common method of the workshop, but for Threaded holes with too small holes or too broken taps holes too, it may not suit, but you can try it).
2. Weld a hexagonal handle or nut on the tap breaking section, then reverse it gently (it’s a good method, but welding is a little embarrassing. If it is always the same, it is not suitable taps with smaller diameters));
3. Use special tools: the tap dissolving.
It causes the discharge and corrosion of the work room to the tap, then eliminates the pliers with the needle nose, etc., which will cause little damage to the inner hole;
4. Use a small hammer to hit the fissure from the tap. (Method it is a little wild. If the diameter of the tap is too small, it is not easy to use. If the diameter is too large, it will be quite tiring to hit it);
5. Weld the wire hole where the broken tap is located, grind it flat and remedy it. lifting and tapping.
6. Chop a zigzag on the transverse section of the broken tap and screw it in the opposite direction with a screwdriver (this zigzag is difficult to chisel, and it will be even more difficult if the diameter of the tap is small);
7. Drill the threaded hole in the broken tap, then incorporate a sleeve or a screw spindle or something, then weld, grind and restart the hole and type it. , it’s very practical.
8. Use electrical pulses to remove them, electric sparks or a cut of wire, if the hole is damaged, you can alcoate the hole and add a wire screw (this method is simpler and more practical. As for Coaxiality, do not envisage for the moment, unless your threaded hole is the same.
9. Make a simple tool to insert the drain space of the chip in the transverse section of the broken tap and carefully remove it in the opposite direction. (The number of parts is the same as the number of slot machines.) Insert into the empty groove of the tap and the broken nut, then use the hinge to pull the square tenon in the output direction and remove the broken tap (The theme of this method consists in opening the drainage groove of the broken tap chip and using the steel wire, preferably a key specifically for the break-ups with steel needles. Make a key like this );
10. The nitric acid solution can corrode steel taps at high speed and not close the parts;
11. Anneal the tap with a acetylene flame or a blowing, then use the forest to pierce. The center to prevent the thread from being damaged.
12. Use a gas drill to reverse the draw, it all depends on the sensation, because it is not a question of drilling the valve outside directly;
13. You can use a crusher to smooth the part of the broken thread, then pierce it first with a small forest, then gradually change towards a larger forest. Tap size to redo your teeth.
14. Weld an iron rod on the broken object and twist it. (Disadvantages: Too small broken objects cannot be welded; the welding skills are extremely demanding and it is easy to burn the room; the welding points are easy to break, and the risk of removing broken objects is very small ))
15. Pry with a cone -shaped tool which is more difficult than the break. (Disadvantages: suitable only for fragile cuts, breaks the cuts, then remove them slowly; the cuts are too deep or too small to remove them; it is easy to destroy the original hole)
16. Make a hexagonal electrode smaller than the diameter of the cutting, use an electric spark machine tool to treat a hexagonal counter hole on the cut, then twist with an Allen key. (Disadvantages: Useless for rusty or stuck stuttering drums; Useless for large parts; useless for too many small berths; long and embarrassing)
17. Use a smaller electrode than the rupture object and use an electric spark machine to pull it. (Disadvantages: Useless for large parts and cannot be placed in the electrical workshop of the machine machine;
18. Use an alloy drill to pierce (drawbacks: easy to destroy the original hole; useless for hard cuts; the alloy forest is fragile and easy to break)
19. There is now a portable tool machine designed and manufactured using the principle of electrical machining, which can easily and quickly remove the screw bodie.
20. If the screw is not too hard, you can flatten the end side, then find the central point, use the sample to punch it in the opposite.
21. If you cannot buy a briefing, use a larger forest to continue breastfeeding the hole. To touch up.
22. If the screw is exposed or if the break of the screw is not strictly required, it can be sawn with a hand saw, and the seam of the blade can be sawn, and the external shell can be sawn, then removed With a flat screwdriver mouth.
23. If the broken thread is exposed to a certain length outside and the melting point of the mechanical material is not too low, you can use the electric welding to weld a terrum in the shape of a towl , so that it can be easily screwed from the welded stem.
24. If the screws are very rusty and it is difficult to manage the above method, it is recommended to roast them with the fire and add a little lubricant, then to use the corresponding method above To cope with it.
25. After a lot of effort, although the screws were removed, the holes were also put back at that time, so pierce a bigger hole to type. Enter the screws, or weld the death thread directly, then pierce small holes in the center of the large screw to type. However, the problem of the structure of internal metals after welding is sometimes difficult to exploit.
