How to remove agricultural machinery broken bolt
First, remove the sludge from the broken surface of the bolt. Smash the center of the section with the center pin. Then use a drill with a diameter of 6-8 mm to drill the hole at the center of the section. Note that the hole must be drilled. After the hole is drilled, the small drill bit is removed, and the drill bit with a diameter of 16 mm is replaced, and the hole of the broken bolt is further expanded and drilled.
Second, take a diameter of 3.2 mm below the electrode, the use of medium and small current in the broken bolt hole in the surfacing from the inside to the outside, the beginning of the surfacing to take off the entire length of the bolt can be half. Begin arcing at the beginning of the welding process so as not to burn the outer wall of the broken bolt. After surfacing to the upper end of the broken bolt, a cylindrical body with a diameter of 14-16 mm and a height of 8-10 mm is continuously welded.
3. After the surfacing is completed, the end face is hammered with a hand hammer, so that the broken bolt generates vibration in the axial direction. Due to the heat generated by the arc and subsequent cooling, coupled with the vibration at this time, loosening occurs between the broken bolt and the thread of the body.
4. Observe carefully. When traces of rust leaking from the fracture are found after tapping, the M18 nuts can be placed on the surfacing stigma and the two are welded together.
5. After the welding, it is slightly cool, and it can be twisted back and forth with the plum wrench around the nut, or it can be twisted back and forth while tapping the nut end face with a small hand hammer, so that the broken bolt can be taken out.
6. After taking out the broken bolts, use the appropriate silk hammer to process the threads in the frame again to remove the rust and other impurities in the holes.
