The working process of the utility model is as follows:

the qualified aluminum alloy rectangular rods obtained by casting are hung horizontally on the storage platform 1 by a travelling crane, and are sequentially conveyed to the tail end of the storage platform by a chain conveyor or a roller conveyor, and after an induction device arranged at the tail end of the storage platform detects that the aluminum alloy rectangular rods are in place, the control system controls the blocking cylinder 114 of the blocking mechanism 11 to act, so that the crutch frame 113 is jacked up, and the aluminum alloy rectangular rods are blocked. At the moment, the chain conveyor stops moving forwards, then the push rod of the blocking cylinder returns to the original position, and the crutch frame is put down. Then, the lift cylinder 24 of bar jacking device 2 moves, the cylinder push rod contracts, scissor fork elevating system 23 risees, slowly holds up the aluminium alloy rectangular stick in the foremost on the storage platform with bracket 27, and base cylinder 212 starts afterwards, promotes the base track along the line and moves ahead, and the notch has been seted up towards one side of bracket 27 to the pay-off frame, and bracket 27 puts into the pay-off frame 3 through the aluminium alloy rectangular stick that the notch on the pay-off frame will hold up. Then the lifting cylinder 24 of the bar jacking device 2 acts, the push rod of the cylinder extends out, the scissor fork lifting mechanism 23 lowers, the bracket 27 descends, and then the base cylinder 212 is started to pull the base to retreat along the line rail. The feeding frame 3 operates to feed the aluminum alloy rectangular rods into the rod shearing machine 4, and the aluminum alloy rectangular rods pass through the cutter cylinder 42 and are sheared into short rods with uniform sizes by the cutter head 43. The cut square rods fall on the guide conveying line 5, and are conveyed to the sorting steering conveyor 6 by the reducing guide mechanism 51 after being tidily arranged in posture in the forward conveying process along the chain plate conveyor. After the aluminum alloy square bars enter the sorting steering conveyor, when the aluminum alloy square bars on the roller conveying line are observed and found to be unqualified bars, the air cylinder 632 is started, the push rod of the air cylinder is controlled to retract, the sliding plate 634 is driven to lift up, a channel in the second portal frame is opened, and the unqualified bars of the aluminum alloy fall into a waste material box arranged at the rear end of the roller conveyor through the second portal frame 631. When the aluminum alloy square bar on the roller conveying line is a qualified bar, the air cylinder push rod is pushed out to push the sliding plate down, the aluminum alloy bar is prevented from moving forwards, the driving lever motor 623 is started to drive the conveying chain mechanism to move, and the driving gear 622 pulls out the qualified aluminum alloy bar to the transition conveying line 7 and continues to convey the qualified aluminum alloy bar to the regular conveyor 8. The regular conveyor conveys alloy square rods one by one to the chain conveyor 82, the conveying chain drives the alloy square rods to move forwards in sequence, when a sensor 83 on the front senses that the alloy square rods are in place, information is transmitted to the control system, the control system immediately starts a first air cylinder 85 of a front group of blocking mechanisms to drive the regular blocking mechanisms 84 to ascend, the alloy square rods are blocked by the front group of regular blocking mechanisms to stop advancing, a front group of second air cylinders 86 immediately starts, plane push plates at the front ends of the air cylinders simultaneously press the end faces of the alloy square rods from two sides until the planes of the push plates on two sides are completely attached to the end faces of the alloy square rods, the posture of the alloy square rods is adjusted to be perpendicular to the conveying direction of the conveying chain, and the posture of a single alloy square rod is adjusted. After the posture of the alloy square rod is arranged, the control system controls the first air cylinder of the front group of regular blocking mechanisms to drive the regular blocking mechanisms to descend, the push rod of the second air cylinder retreats, the square rod with the regular posture continues to move forwards, when the rear sensor 83 senses that the alloy square rod is in place, information is transmitted to the control system, and the control system immediately starts the first air cylinder 85 of the rear group of regular blocking mechanisms to drive the regular blocking mechanisms 84 to ascend and be blocked by the rear group of regular blocking mechanisms. The alloy square bar that the orderly stop gear of a preceding set of regular stop gear was put in order is under the stopping of a set of regular stop gear behind, the sequence is arranged and is drawn close, when the alloy square bar accumulated to setting for the radical, control system control first cylinder of a set of regular stop gear at the back drove regular stop gear and descends, chain conveyor 82 will draw close a set of alloy square bar and continue to carry backward, be blocked by split heads shape dog 89, and keep arranging neatly under the supporting leg that stretches forward two split heads shape dog and the mating action of the conveying chain that moves ahead. And then grabbing and placing the whole row of alloy square rods to a subsequent stacking station of a finished product line 9 by using a manipulator of the palletizing robot 10. Under the linkage of the clamping plate cylinder 104 and the gripper cylinder 105, the clamping plates 102 on the two sides of the manipulator are linked with the front and rear L-shaped grippers 103, so that a row of aluminum alloy square rods A which are orderly arranged are stably grabbed and conveyed to the positioning bracket 92 of the stacking station on the finished product line. When the aluminum alloy square rods on one stacking station of the finished product line are stacked to the specified number of layers, the finished product line moves forward by one station, is packaged by the packaging device 93, and can be stacked after being packaged. The overshoot-proof support 94 arranged at the rear end of the stacking chain conveyor can prevent the packed bag from toppling over, and production safety is guaranteed.
