Tubaeform collecting hood and joint are provided with, the joint can be inhaled dust caused by weld zone by the external dust catcher of flexible pipe
Walk, dust collector volume is little, but because it is arranged on the Mobile base of workpiece, can be moved with workpiece, therefore
Pick-up performance can be guaranteed.
To realize the cleaning of surfaces to be welded function of the present embodiment, a steel nail brush is provided with, the steel nail brush can be relative to roll
External cylindrical surface realizes the action that moves forward and backward, therefore, being provided with the 3rd motor, passes through power drive caused by the 3rd motor and its
The leading screw rotation of connection, leading screw form screw pair with hollow shaft, and hollow shaft is under the limitation of lance, it is impossible to rotary motion, can only
Elastic motion, and steel nail brush is connected with hollow shaft, then passing through the 3rd motor can realize steel nail brush relative to roller surface
Elastic motion.When roll is in welding job state, steel nail brush backs to extreme position, is not connect with roller surface
Touch；After an impulse stroke has been welded, the welding slag of face of weld need to be cleared up, to improve welding quality, now, steel nail
Brush proceeds to suitable operating position.For the advance of limitation steel nail brush or retracted position, two limit switches are provided with, pass through lance
Generation switching value is functioned, realizes the break-make to the 3rd motor power.
The course of work of the present embodiment is as follows：
Job step 1：After placing workpiece, by starting the first motor and the second motor, workpiece is adjusted to weld
Connect the original position on the right of stroke, subsequent first motor and the second motor stalling；Start external dust catcher；
Job step 2：Point burner, rotary roller, the pre-heat treatment is carried out to roll, then striking and opens welding agent powder
Switch, while the second motor of startup and the 4th motor, Lincoln weld, preheating and the synchronous progress of welding are carried out, in working position
Put, preheating position is before welding position；
Job step 3：After having welded an impulse stroke, the second motor and the stalling of the 4th motor, burner extinguish, and start
First motor and the second motor, workpiece is adjusted to correct position, then stalls the first motor and the second motor；Then open
Dynamic 3rd motor, steel nail brush, which stretches out, is pressed on roll working surface；Roller rotational, start the second motor, drive wire brush edge to roll
Roller axially carries out feed motion.After completing cleaning of surfaces to be welded work, start the 3rd motor, wire brush is backed to limit position
Put；
According to built-up welding thickness, above-mentioned job step 1-3 is repeated, whole built-up welding work can be completed.
