It is passed through from the first fixture 3 again；
S3：Second reinforcing bar 14 is penetrated from the second steel casing 11 into hollow rotating shaft 4, the second reinforcing bar 14 passes through second
Passed through at the second fixture 5 again at fixture 5 and one end of the second reinforcing bar 14 extend in the first steel casing 9 with the first reinforcing bar 7
Fitting setting；
S4：Finely tune that the first reinforcing bar 7 makes it and the second reinforcing bar 14 is concentric is bonded setting by adjuster 8, at this point, being pressed from both sides with first
Tool 3 is fixed the first reinforcing bar 7, then second reinforcing bar 14 is clamped with hollow rotating shaft 4 with the second fixture 5；
S5：Start propeller 2, propeller 2 promotes the first reinforcing bar 7 to make so as to squeeze the second reinforcing bar 14 to the second reinforcing bar direction
There is between two reinforcing bars initial compression power；
S6：Start driving device 6, that is, the motor in the present embodiment, motor rotation drives pulley rotation and then leads to
Cross belt and drive 4 high speed rotation of hollow rotating shaft, herein, the rotating speed of motor not less than 2500 revs/min, preferably 3000 turns/
Minute, the second reinforcing bar 14 constantly rubs the also just with 4 high speed rotation of hollow rotating shaft during 14 high speed rotation of the second reinforcing bar
One reinforcing bar 7 is so as to generate a large amount of heat so that red, closing motor is burnt in the contact position 17 of the first reinforcing bar and the second reinforcing bar；At this moment after
The continuous propeller 2 that adjusts is so as to increase the propelling pressure of extruding force, herein propeller 2 between the first reinforcing bar 7 and the second reinforcing bar 14
Not less than 15MPa, it is preferred that the propelling pressure of propeller 2 is 20MPa；During extruding, the first reinforcing bar 7 and the second steel
14 forging welding of muscle is together；In order to enable at forging welding after the first reinforcing bar 7 and the welding of the second reinforcing bar 14 diameter and two reinforcing bars it is straight
Diameter after forging welding, starts two box-like hydraulic presses, the pressing tongs of two box-like hydraulic presses is to first quite and without apparent outer convex weld
Apply radial pressure at the forging welding of 7 and second reinforcing bar 14 of reinforcing bar, so as to be squeezed the steel being had more at forging welding and make weld
Form screw-thread steel；Due to the reinforcing bar of unlike material, its component content is different, the temperature and time needed for welding
Different, the temperature and time variation relation figure during reinforcement welding of unlike material, during welding, needs in order to obtain
Record temperature variations on the infra-red thermometer 18 of the contact position 17 of the first reinforcing bar 7 and the second reinforcing bar 14 and time
Relationship, and curve is drawn, it obtains the relational graph of the two, in this way when welding, can be accurately held according to the material of reinforcing bar
Weld interval, so as to prevent energy dissipation；
S7：After welding, the first fixture 3 and the second fixture 5 are unclamped, closes hydraulic device 16, the steel after extraction welding
Muscle, checks welding quality, and welding process terminates；The welding process of the present invention is very fast, and whole process only about needs 3 minutes i.e.
Can, and really weld interval only need 30s, and without any welding rod or welding wire, efficient quick and safe.
Reinforcement welding device according to the present invention and welding method are described in an illustrative manner above with reference to attached drawing.But
It is, it will be appreciated by those skilled in the art that the reinforcement welding device and welding method that are proposed for the invention described above, may be used also
To make various improvement on the basis of the content of present invention is not departed from.Therefore, protection scope of the present invention should be by appended power
The content of sharp claim determines.
