[0059] The red-hot ingot produced by the continuous casting and rolling device is pushed by the automatic pushing device to the position of the cutting device 1000 for flange blank production. The first driving member 1220 drives the clamping arm 1212 to rotate along the rotating axis so that the clamping block 1213 abuts against the first surface of the ingot. The control unit controls the driving motor 1332 to operate so that the car body 1331 moves back and forth along the extension direction of the track. The car body 1331 drives the cutting assembly 1310 connected thereto to approach the ingot. Since the abutting member 1400 is connected to the cutting assembly 1310, The abutment member 1400 approaches the ingot along with the cutting assembly 1310 and abuts against the second surface of the ingot. The first surface and the second surface are arranged opposite to each other. The ingot is clamped between the abutment member 1400 and the clamping block 1213.

The ingot is cut according to a predetermined cutting process. After the cutting is completed, the connecting arm 1312 and the cutting gun 1311 are quickly returned to the original cutting position under the drive of the second driving member 1320. After the cutting action is completed, the first driving member 1220 pulls the clamping arm 1212 to rotate, driving the clamping block 1213 connected to the clamping arm 1212 to move away from the ingot and release the cut product. The third driving member 1120 drives the supporting member 1100 to flip along the flip axis so that the supporting member 1100 and the first driving member 1120 are connected. The seat 1110 is set at an angle, and the cut ingot is flipped and slid to the cut carrying conveyor 2000 by its own gravity. The conveyor conveys the cut ingot to the online sorting device 3000. The online camera 3100 automatically identifies the position and shape of the cut ingot, and according to preset requirements, the three-degree-of-freedom sorting robot 3200 automatically grabs, translates, and stacks the cut finished products, and sorts the cut ingot according to the production process requirements to the corresponding ingot stacking area or the automatic ingot conveying device for the next forging process.
