Referring to fig. 4, after finishing grinding, the motor stops rotating, the frame 27 is moved upward, the frame 27 moves in the first guide rail groove 09 and the second guide rail groove 24 through the first guide rail column 25 and the second guide rail column 26, and first, the frame moves upward to disengage the friction disc 10 from the gear 30, and then, the frame moves horizontally in a direction close to the spline 11 until the second guide rail column 26 moves to the rightmost end of the second guide rail groove 24, at this time, the frame 27 rotates by using the second guide rail column 26 as a rotating shaft, and the first guide rail column 25 moves along the arc-shaped portion of the first guide rail groove 09, so that the friction disc 10 is turned upward and retracted, and the friction disc 10 does not shield the two steel bars during welding, so that the ends of the two steel bars can contact with each other for friction welding.

Friction welding process goes on, after the completion is polished, with the friction disk 10 upset back of receiving, the motor begins the reverse output shaft through this moment and drives spline 11 and rotate, this moment because friction disk 10 breaks away from and gear 30 meshes, thereby gear 30 can not drive friction disk 10 and rotates, the rotation of spline 11 can drive interior wheel 43 and rotate, interior wheel 43 drives the inside ratchet of foreign steamer 44 through pawl 42 and drives foreign steamer 44 and rotate, thereby foreign steamer 44 rotates and can drive ring gear 15 and rotate, ring gear 15 rotates and can drive a section of thick bamboo 14 and rotate, thereby a section of thick bamboo 14 rotates and can rotate on spacing collar 21 through spacing collar 16, thereby a section of thick bamboo 14 can drive the reinforcing bar and rotate in step, it can adjust slide 12 up-and-down motion to rotate screw 13, thereby it drives the reinforcing bar motion to drive a section of thick bamboo 14 motion. After the motor 08 works, the rotating speed of the steel bar driving the clamping cylinder 14 to clamp reaches the highest speed, the screw 13 starts to rotate to enable the steel bar clamped by the clamping cylinder 14 to gradually move towards the direction of the steel bar clamped by the clamping sleeve 04, the friction heat generated during high-speed rotation can heat and melt the end parts of the two contacted steel bars, the screw 13 continues to rotate to enable the steel bar clamped by the clamping cylinder 14 to be downwards extruded into the end part of the steel bar clamped by the clamping sleeve 04, the two steel bar hot melting positions are mutually extruded and fused, the motor is stopped at the moment, the two steel bar hot melting positions can be rapidly cooled at normal temperature, and therefore the welding process is completed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
