The axial alignment device 5 is matched with the ejection rotating device 6 and is mainly used for adjusting the axial direction of the torsion bar piece to be aligned with the central axis of the ejection end head 66, so that the two ejection end heads 66 can conveniently and coaxially clamp the torsion bar piece. In the ejecting rotating device 6, the vertical lifting assembly 62 can drive the ejecting head 66 to synchronously lift along with the two horizontal carrying assemblies 63, when the output end of the lifting cylinder 622 is at the maximum output, the ejecting head 66 is necessarily located at the highest position, and the height position is determined, in which the axial height of the ejecting head 66 and the axial height of the top-pressed and clamped torsion bar member are also determined. In the axial alignment device 5, when the discharging cylinder 51 is in a zero output state, the distance between the two material supporting alignment members 525 is the closest, the cross section of the material supporting portion 5252 is in a right triangle shape, the torsion bar discharged from the discharging device 4 can directly fall between the inclined planes of the two material supporting portions 5252, the alignment effect of the inclined planes of the two material supporting portions 5252 ensures that the torsion bar positioned between the inclined planes of the two material supporting portions 5252 is axially positioned on the same vertical plane as the axial direction of the material ejecting end head 66, when processing is performed on torsion bars with different diameters, the material supporting alignment member 525 is driven to slide along the two fork arm slide rails 5241 by rotating the adjusting screw 526 by only taking the material ejecting end head 66 at the highest position as a reference, so as to adjust the height of the material supporting alignment member 525, the adjustment of the two material supporting alignment members 525 needs to be completed synchronously during the adjustment, so that the two material supporting alignment members 525 can be positioned at the same height, and so that when adjusted, the torsion bar element can be axially aligned to coincide with the axial alignment of the ejection tip 66 when it falls between the ramps of the two stock-holding portions 5252.

Before actual processing, the adjustment of the axial alignment device 5 needs to be completed, in addition, according to the specific length of the torsion bar member to be processed, the stroke of two horizontal carry assemblies 63 in the ejection rotating device 6 needs to be adjusted, specifically, when two ejection cylinders 631 are synchronously started to enable two ejection ends 66 to move in opposite directions, and when the two ejection cylinders are moved to a stop state, the distance between the inner end faces of two ejection grooves 6611 in the two ejection ends 66 should be slightly smaller than the length of the torsion bar member to be processed, so that the ejection clamping of the torsion bar member can be better realized.

During actual processing, the torsion bars to be processed are conveyed downwards one by the blanking device 4, the blanked torsion bars fall between the inclined planes of the two material supporting portions 5252 of the axial alignment device 5 and are in a state of being axially aligned with the material ejecting ends 66, then the two horizontal carry assemblies 63 are synchronously started to drive the two material ejecting ends 66 to move towards each other, finally the torsion bars are jacked and clamped between the two material ejecting ends 66, then the starting output end of the emptying air cylinder 51 extends downwards, the two connecting rods 523 are driven to drive the two rocker arms 522 to rotate, the rocker arms 522 drive the rotating shaft 521, the double-fork frame 524 and the material supporting alignment member 525 to synchronously rotate therewith, then the two material supporting alignment members 525 rotate towards two sides and open to avoid the tightly jacked torsion bars, then the two vertical lifting assemblies 62 are synchronously started to drive the torsion bars to synchronously descend to the lowest height position along with the two material ejecting ends 66, the torsion bar will press against the polishing belt 33.
