When the piston rod of the clutching oil cylinder 41 gradually extends, one end of the shifting fork 37 close to the sliding sleeve 31 is driven to decline gradually, and at the same time, one end of the shifting fork 37 away from the sliding sleeve 31 gradually rises. The shifting fork 37 drives the sliding sleeve 31 to slide downwardly on the driving rod 29 by two sliding blocks 35 until the upper-side clutching column 32 is embedded into the lower-side clutching column 27, and the shifting fork 37 drives snapping block 45 to slide upwardly until it completely enters the interior of the upper-side snapping groove 43. Since the snapping block 45 is detached from the lower-side snapping groove 44, the rotation frame 22 and the driving frame 17 can rotate relative to each other.

Since the second sliding block inside the sliding sleeve 31 is slidably inserted into an interior of the second sliding groove 30 on the driving rod 29, the sliding sleeve 31 drives the driving rod 29 to rotate, and the driving rod 29 drives the rotation frame 22 to rotate around the axis of the driving roller 19. When the rotation frame 22 rotates, the T-shaped block 24 at the lower end rotates inside the T-shaped groove 23 on the upper end of the driving frame 17, so as to ensure that the rotation frame 22 will not detach from the driving frame 17.

The method of use of the present disclosure includes the following steps.
Step 1: before the processing device works, the sliding oil cylinder 11, the lifting oil cylinder 57, the clutching oil cylinder 41, the down-pressing oil cylinder 12, and the inner-supporting oil cylinder 66 are all in the contracted state, at which time the sliding base 7 is located at the foremost side; the lifting table 54 drives the upper-side driven roller 59 to be at the highest point; the inner-supporting clamping mechanism 60 inside the upper-side driven roller 59 is in a contracted state; and the driving frame 17 is in a locking state with the rotation frame 22.
Step 2: when the produced flange workpiece is required to undergo a stress eliminating process, the workpiece is conveyed to the back end via the feeding conveying roller 2 first; then the driving roller 19 controls to rotate by the driving motor 18 via the speed reducer; and at the same time the piston rod of the clutching oil cylinder 41 is controlled to extend out, wherein the piston rod of the clutching oil cylinder 41 drives one end of the shifting fork 37 close to the sliding sleeve 31 to gradually decline, and at the same time one end of the shifting fork 37 away from the sliding sleeve 31 gradually rises, wherein the shifting fork 37 drives the sliding sleeve 31 to slide downward on the driving rod 29 by two sliding blocks 35 until the upper-side clutching column 32 is embedded into the lower-side clutching column 27, and the shifting fork 37 drives the snapping block 45 to slide upwardly until fully entering the interior of the upper-side snapping groove 43. Since the snapping block 45 is detached from the lower-side snapping groove 44, the rotation frame 22 and the driving frame 17 can rotate relative to each other. At this time, the lower-side clutching column 27 drives the upper-side clutching column 32 to rotate, and the upper-side clutching column 32 drives the sliding sleeve 31 to rotate. Since the second sliding block inside the sliding sleeve 31 is slidably inserted into the interior of the second sliding groove 30 on the driving rod 29, the sliding sleeve 31 drives the driving rod 29 to rotate, and the driving rod 29 drives the rotation frame 22 to rotate around the axis of the driving roller 19, wherein when the rotation frame 22 rotates, the T-shaped block 24 at the lower end rotates inside the T-shaped groove 23 on the upper end of the driving frame 17, so as to ensure that the rotation frame 22 will not detach from the driving frame 17. The rotation frame 22 drives the upper-side moving frame 49, the lifting table 54, and the upper-side driven roller 59 to rotate above the axis of the workpiece as a whole, and then driving motor 18 stops rotating.
Step 3: the piston rod of the control lifting oil cylinder 57 is controlled to extend out, so that the lifting table 54 drives the upper-side driven roller 59 to move downwardly as a whole until the lower end of the upper-side driven roller 59 is inserted into the interior of the workpiece, wherein the lower end of the lower-side driven roller 76 is flush to the lower end of the workpiece; and then the piston rod of the inner-supporting oil cylinder 66 is controlled to extend out, wherein the piston rod of the inner-supporting oil cylinder 66 drives the sliding column 64 to slide downwardly through the cooperation between the linkage sleeve 67 and the linkage ring 68, so that the connecting rod 65 between the sliding column 64 and the inner-supporting plate 61 gradually opens outwardly. Four inner-supporting plates 61 gradually extend outwardly until they are in close contact with the inner wall of the workpiece, wherein the telescopic rod 69 is horizontally arranged to ensure that the inner-supporting plate 61 extends out horizontally and outwardly. Four inner-supporting plates 61 stably support the inner wall of the workpiece by the extrusion of the piston rod of the inner-supporting oil cylinder 66, so that the workpiece can be lifted upwardly by four inner-supporting plates 61.
Step 4: the piston rod of the lifting oil cylinder 57 is controlled to withdraw, and the workpiece is lifted up by four inner-supporting plates 61; and then the driving motor 18 is controlled to rotate reversely, wherein the driving motor 18 drives the rotation frame 22 to rotate reversely by the speed reducer, the driving rollers 19, and the clutch mechanism 26, and the rotation frame 22 drives the upper-side moving frame 49 to rotate reversely, wherein when the upper-side moving frame 49 drives the upper-side driven roller 59 and the workpiece to rotate as a whole to the upper part of the down-pressing roller base 15, the driving motor 18 stops rotating reversely.
Step 5: the piston rod of the control lifting oil cylinder 57 is controlled to extend out, so that the upper-side driven roller 59 drives the workpiece gradually decline until the workpiece comes into contact with the down-pressing roller 16 on the down-pressing roller base 15, at which time the axis of the workpiece coincides with the axis of the down-pressing roller base 15; and next the piston rod of the inner-supporting oil cylinder 66 is controlled to withdraw and the sliding column 64 is controlled to slide upwardly, wherein the inner-supporting plate 61 is gradually withdrawn by the connecting rod 65 until the outside circular arc surface of the inner-supporting plate 61 coincides with the outside cylindrical surface of the upper-side driven roller 59.
Step 6: the piston rod of the clutching oil cylinder 41 is controlled to withdraw, wherein the piston rod of the clutching oil cylinder 41 drives one end of the shifting fork 37 close to the sliding sleeve 31 to gradually rise, and at the same time one end of the shifting fork 37 away from the sliding sleeve 31 gradually declines, wherein the shifting fork 37 drives the sliding sleeve 31 to slide upwardly on the driving rod 29 by two sliding blocks 35 until the upper-side clutching column 32 completely detaches from the lower-side clutching column 27, wherein the clutching spring 34 is in a compressed state, and the shifting fork 37 drives the snapping block 45 to slide downward until entering the interior of the junction between the upper-side snapping groove 43 and the lower-side snapping groove 44. The driving frame 17 and the rotation frame 22 cannot rotate relative to each other due to the limitation of the snapping block 45, i.e., the rotation frame 22 is limited to the default position. At this time, since the upper-side clutching column 32 detaches from the lower-side clutching column 27, the lower-side clutching column 27 does not drive the upper-side clutching column 32 to rotate and the upper-side clutching column 32 no longer drives the rotation frame 22 to rotate even if the driving motor 18 drives the driving roller 19 to rotate by the speed reducer.
Step 6: the piston rod of the control lifting oil cylinder 57 is controlled to extend out continuously until two spiral grooves 79 of the upper-side butting column 77 are embedded into two spiral grooves 79 of the lower-side butting column 78, at which time the lower end of the upper-side driven roller 59 is in contact with the upper end of the lower-side driven roller 76, so that the upper-side driven roller 59 and the lower-side driven roller 76 can rotate synchronously in the same direction.
Step 7: the piston rod of the sliding oil cylinder 11 is controlled to extend out, so that the sliding oil cylinder 11 drives the sliding base 7 to move backward as a whole until the up-pressing roller base 13 moves above the down-pressing roller base 15 and coincides with the axis of the down-pressing roller base 15; and then the piston rod of the down-pressing oil cylinder 12 is controlled to extend out, so that the up-pressing roller base 13 gradually declines until the up-pressing rollers 14 on the up-pressing roller base 13 are all in close contact with the surface of the workpiece.
Step 8: the driving motor 18 is controlled to start rotating, and at the same time the piston rods of the upper-side pressing oil cylinder 53 and the lower-side pressing oil cylinder 74 are controlled to gradually extend, so that the upper-side moving frame 49 and the lower-side moving frame 70 synchronously move backward, and the upper-side driven roller 59 and the lower-side driven roller 76 also synchronously move backward, wherein the flange workpiece is driven to move backward together until the flange workpiece is contacted with the driving roller 19 that is rotating. The piston rods of the upper-side pressing oil cylinder 53 and the lower-side pressing oil cylinder 74 gradually extend, so that the flange workpiece is extruded by both the upper-side driven roller 59 and the driving roller 19, and at the same time, the piston rod of the down-pressing oil cylinder 12 continuously extends, so that the up-pressing roller 14 on the up-pressing roller base 13 always extrudes the upper-end surface of the workpiece, wherein the flange workpiece, the upper-side driven roller 59, and the lower-side driven roller 76 always rotate under the drive of the driving roller 19, so that the inside cylindrical surface, the outside cylindrical surface, the upper-end surface, and the lower-end surface of the flange workpiece are always in the extrusion state, so as to eliminate the residual stress inside the flange workpiece.
Step 9: the piston rod of the down-pressing oil cylinder 12 is controlled to withdraw, wherein the up-pressing roller 14 on the up-pressing roller base 13 is detached from the workpiece; the piston rod of the control sliding oil cylinder 11 is controlled to withdraw, wherein the sliding base 7 slides to the foremost side, at which time the upper part of the workpiece is in a completely open state; the piston rod of the lifting oil cylinder 57 is controlled to withdraw, so that the lower end of the lower-side driven roller 76 is flush to the lower end of the workpiece; the piston rod of the inner-supporting oil cylinder 66 is controlled to extend, so that the inner wall of the workpiece is tightly supported by four inner-supporting plates 61 again; and next the piston rod of the control lifting oil cylinder 57 is controlled to withdraw continuously, so that the lifting table 54 drives the workpiece to gradually rise via the upper-side driven roller 59, and the workpiece is detached from the down-pressing roller 16 on the down-pressing roller base 15
Step 10: the driving motor 18 controls the driving roller 19 to rotate reversely by the speed reducer, and at the same time controls the clutch mechanism 26 to unlock the rotation frame 22 from the driving frame 17, at which time the lower-side clutching column 27 drives the upper-side clutching column 32 to rotate; the upper-side clutching column 32 drives the sliding sleeve 31 to rotate; the sliding sleeve 31 drives the driving rod 29 to rotate; the driving rod 29 drives the rotation frame 22 to rotate around the axis of the driving roller 19; and the rotation frame 22 drives the upper-side moving frame 49, the lifting table 54, and the upper-side driven roller 59 as a whole to rotate above the back end of the discharging conveying roller 3, and the driving motor 18 stops rotating.
Step 11: the piston rod of the control lifting oil cylinder 57 is controlled to extend out, wherein the workpiece is placed at the back end of the discharging conveying roller 3; then the piston rod of the inner-supporting oil cylinder 66 is controlled to withdraw and the sliding column 64 is controlled to slide upwardly, wherein the inner-supporting plate 61 is gradually withdrawn by the connecting rod 65 until the outside circular arc surface of the inner-supporting plate 61 coincides with the outside cylindrical surface of the upper-side driven roller 59; and the piston rod of the lifting oil cylinder 57 is controlled to withdraw, so that the lifting table 54 and the upper-side driven roller 59 return to the initial height.
Step 12: the driving motor 18 is controlled to rotate, so that the upper-side driven roller 59 returns to the upper part of the axis of the down-pressing roller base 15 again; and the clutch mechanism 26 is controlled to lock the rotation frame 22 with the driving frame 17 again, at which time the processing device returns to the initial state and waits to process the next workpiece.
