[0038] In summary, when the axle blanks are subjected to surface treatment, they are first placed in groups at the input end of the conveyor roller 2, with the number of axle blanks in each group being 3; the conveyor roller 2 conveys the axle blanks to the cleaning chamber of the shot blasting section 1 for surface treatment of the axle blanks;

[0039] After the surface treatment, the axle blank is transported by the conveyor roller 2 to the top of the vertical track 3, at which point the operation of the conveyor roller 2 is suspended. Prior to this, the travel motor 513 drives the unloading transfer vehicle 5 to move along the vertical track 3 toward the conveyor roller 2, so that the support plate 54 on the top of the second telescopic cylinder 53 moves to a position facing the conveyor roller 2.

[0040] The position detection device ensures that the three axle blanks in a group are transferred to the position corresponding to the storage slot 541 on the support plate 54 at the top of the second telescopic cylinder 53. At this time, the second telescopic cylinder 53 extends, causing the support plate 54 to lift the axle blanks upward and separate them from the conveyor roller 2. The travel motor 513 then drives the unloading transfer vehicle 5 in the direction of the flipping sootblowing assembly 6. During the movement, the support plate 54 passes through the notch of the conveyor roller 2.

[0041] When the axle blank is transported to a position corresponding to the bell-mouth shell 68, the operation of the travel motor 513 is stopped; at this time, the clamping telescopic cylinder 65 is extended, so that the movable frame 66 moves under the guidance of the guide groove wheel 67 and the guide rod 641, so that the bell-mouth shell 68 is respectively stuck at the two end heads of the axle blank; at this time, the travel motor 513 drives the unloading transfer vehicle 5 to move as a whole to the unloading station to carry out the unloading process of the next group of axle blanks; at the same time, the rotating frame 63 is driven to flip upward around the intersection axis at the top of the articulated bracket 61, and stops flipping when the flipping angle is about 75°. At this time, the electromagnetic pulse valve controls the air intake of the bell-mouth shell 68 at one end, and this high-pressure gas purges the hollow cavity of the axle blank. The purged impurities enter the dust removal equipment through the bell-mouth shell 68 and the pipeline at the other end to collect the impurities;

[0042] After completing the process of blowing the hollow cavity of the axle blank, the rotating frame 63 rotates to reset; at this time, the axle blank that has completed the blowing just falls into the storage groove 541 on the top support plate 54 of the first telescopic cylinder 52; the walking motor 513 runs, so that the next group of unloaded axle blanks are transferred to the bottom of the rotating frame 63, and the previous group of axle blanks that have completed the blowing are transferred to the top of the unloading rack 4, and the first telescopic cylinder 52 contracts, so that the axle blanks that have completed the blowing are placed on the unloading rack 4, and the unloading, flipping, soot blowing and unloading processes are completed for each group of axle blanks in turn.
