How can I remove the broken screw
Beijing KTcaster to find out how to remove the broken screw?
1. After the hole is drilled through, remove the small drill bit,
replace it with a drill bit with a diameter
of 16mm, and continue to expand and drill through the broken bolt
hole. Firstly, remove the sludge
on the surface of the broken screw and the broken head, use the
central gun to kill the central gun
of the section, and then use the electric drill to install a drill
bit with a diameter of 6-8mm to drill at the
central gun hole of the section. Note that the hole must be drilled
through.
2. When starting surfacing, the arc striking shall not be too long
to avoid burning through the outer
wall of the broken bolt. After surfacing to the upper end face of
the broken bolt, continue surfacing
to produce a cylinder with a diameter of 14-16mm and a height of
8-10mm. Take the welding rod with
a diameter of less than 3.2mm and weld the broken bolt from inside
to outside with medium and small
current. At the beginning of surfacing, take half of the whole
length of the broken bolt
3. After surfacing, hammer the end face with a hand hammer to make
the broken bolt vibrate along its
axis
4. After careful observation, when a small amount of rust is found
to leak from the fracture after
knocking, M18 nut can be sleeved on the surfacing column head and
welded.
5. After welding, cover the nut with a ring wrench while it is hot,
twist it left and right, or knock the end
face of the nut with a small hammer while twisting it back and
forth, so as to take out the broken bolt.
6. After taking out the broken bolt, process the screw thread in
the frame with a suitable screw hammer
to remove rust and other sundries in the hole.
