It is transferred to repair welding workshop and carries out repair welding processing, next procedure is directly carried out not above the blank of 1.5mm to discovery mandril print depth；
(2) on the basis of the first step, a sequence machining is carried out to the blank of bus wheel, is processed in the blank of bus wheel
After one sequence black-skin surface, need 100% inspection machined surface whether have cinder hole slag inclusion etc. it is solderable fill a vacancy it is sunken, if any, then stop plus
Work is made to determine whether can to weld repair welding to problem product, determine can with repair welding, by machine shop deliver soldering workshop into
Row repair welding, is unable to repair welding, scraps, if not finding the solderable sunken defect of filling a vacancy such as cinder hole slag inclusion, carries out in next step；
(3) on the basis of second step, the blank of bus machine is continued to process, process processes a sequence, does not find slag
Hole etc. continues to process two sequences etc., and discovery has cinder hole, is worked into whole completions, then determining whether can be with repair welding, can be with repair welding
, repair welding workshop is delivered by machine shop and carries out repair welding, repair welding is unable to, scraps；
(2) repair welding is processed
(4) it receives to repair welding blank or semi-finished product；
(5) with cutter reject cinder hole be mingled in sundries, welding repair welding then is carried out to fault location with argon arc welding machine；
(6) solder joint is polished flat and is polished with grinding device and burnishing device；
(7) sanding and polishing position is cleaned with Clean- alcohol, checks whether sanding and polishing is qualified for sanding and polishing position, if
It is unqualified, then continue sanding and polishing until qualification, then delivers machine shop and carry out next procedure；
(8) for processing a sequence with regard to the semi-finished product after carrying out repair welding cinder hole of stopping work, machine shop Vehicle Processing is delivered back
Repair welding position and continue later process processing without pass through (6) step and (7) step.
Preferably, the grinding device in the step 6 is using the sander of polishing grinding wheel, and burnishing device is using throwing
The polishing machine of light sisal piece.
Further, when polishing in the step 6, polishing agent is placed in the polished silicon wafer of burnishing device.
Preferably, the cutter in the step 5 is drill bit or white steel blade.
Preferably, the material of welding rod color used by the argon arc welding machine in the step 5 and the bus wheel for wanting repair welding
The color that color is presented after repair welding is identical.
Preferably, the polishing agent in the step 6 is purple cured.
Beneficial effect
The invention has the benefit that
Show the bus wheel wheel hub after reparation in mechanical property by carrying out Physical Experiment to the bus wheel wheel hub after reparation
Aspect be no different with normal wheel hub and also can also accomplish it is unnecessary scrap, with reach save cost its equally there is bond strength
Big feature, while the present invention has the features such as easy to operate, recombination rate is high.
