Abstract

The invention discloses a method for unscrewing decollated bolts. The method includes following steps: (1) flattening the cracking position of a decollated bolt on a connector; (2) drilling a hole with the diameter smaller than the outer diameter of the decollated bolt and the depth ranging from 10-20mm along a central line of the decollated bolt at the flattened position; (3) selecting a suitable hand tapping tool according to the diameter of the drilled hole, and tapping the drilled hole with the hand tapping tool to enable the thread direction in the drilled hole to be opposite to the thread direction of the decollated bolt; and (4) screwing a small bolt into the tapped threaded hole with a wrench. Since the thread direction in the drilled hole is opposite to the thread direction of the decollated bolt, the decollated bolt can be slowly unscrewed during the screwing process of the small bolt. The method for unscrewing decollated bolts is easy to handle, convenient and fast, and can protect the connector from deformation and damage caused by damages by external force.

Description

A kind of decollation bolt removing method
Technical field
The invention belongs to the production of cigarettes technical field, relate in particular to a kind of decollation bolt removing method.
Background technology
In plant equipment, it is a kind of connected mode commonly used that bolt connects, and bolt is connected some occasion; Such as outdoor, because environment is abominable, the bolt carbonization or the dead phenomenon of becoming rusty are serious; Often cause in the demounting bolt process between some bolt heads and the body of bolt bottom and break off, the body of bolt is difficult to take out, and adopts not only complex operation of conventional method (welding new bolt head card body, boring square steel wedging etc.); And be prone to cause connector to damage, lose more than gain.
Summary of the invention
The present invention is in order to solve weak point of the prior art, and a kind of easy operating, safe and reliable decollation bolt removing method are provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of decollation bolt removing method, and comprise and adopt following steps successively,
(1), frustrate the breaks of decollation bolt on the connector flat;
(2), hole along the center line of decollation bolt, the aperture is less than the external diameter of the body of bolt, and drilling depth is at 10-20mm at the flat place of the stranding of decollation bolt;
(3), choose suitable hand tapping utensil, use the hand tapping device that tapping is carried out in the hole of being bored, the thread rotary orientation in the hole is opposite with the thread rotary orientation of decollation bolt according to the pore size of boring;
(4), use in the screwed hole after stove bolt of wrench operated screw into tapping; Because the thread rotary orientation in the hole is opposite with the thread rotary orientation of decollation bolt; In stove bolt precession process, just drive decollation bolt and screw out lentamente, so just decollation bolt is disassembled in connector.
Adopt technique scheme; The present invention improves on the basis of using for reference wedging square steel principle; To connect firmly and change screwed connection into; Eliminated the destruction of stress effect to the connector screw, because the rotation direction of the stove bolt of institute's precession is identical with the disassembly direction that is disassembled decollation bolt, decollation bolt will be by under the easy removal simultaneously.The present invention is easy to grasp in application, and is convenient and swift, and guarantees that connector does not receive outside destroy and deformed damaged.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, a kind of decollation bolt removing method of the present invention comprises and adopts following steps successively:
(1), frustrate the breaks of decollation bolt 2 on the connector 1 flat;
(2), hole 3 along the center line of decollation bolt 2, the aperture is less than the external diameter of decollation bolt 2, and drilling depth is at 10-20mm at the flat place of the stranding of decollation bolt 2;
(3), choose suitable hand tapping utensil, use the hand tapping device that tapping is carried out in the hole of being bored, the thread rotary orientation in the hole 3 is opposite with the thread rotary orientation of decollation bolt 2 according to the pore size of boring;
(4), use in the screwed hole 3 after stove bolt 4 of wrench operated screw into tapping; Because the thread rotary orientation in the hole 3 is opposite with the thread rotary orientation of decollation bolt 2; In stove bolt 4 precession processes; Just drive decollation bolt 2 and screw out lentamente, so just decollation bolt 2 is disassembled in connector.

Claims (1)

1. decollation bolt removing method is characterized in that: comprises and adopts following steps successively,
(1), frustrate the breaks of decollation bolt on the connector flat;
(2), hole along the center line of decollation bolt, the aperture is less than the external diameter of decollation bolt, and drilling depth is at 10-20mm at the flat place of the stranding of decollation bolt;
(3), choose suitable hand tapping utensil, use the hand tapping device that tapping is carried out in the hole of being bored, the thread rotary orientation in the hole is opposite with the thread rotary orientation of decollation bolt according to the pore size of boring;
(4), use in the screwed hole after stove bolt of wrench operated screw into tapping; Because the thread rotary orientation in the hole is opposite with the thread rotary orientation of decollation bolt; In stove bolt precession process, just drive decollation bolt and screw out lentamente, so just decollation bolt is disassembled in connector.
