1. the bars sheared by the double-length flying shears 1 fall into the tooth grooves of the cooling bed body 3 through the cooling bed input roller way 2, 5 bars of 96 meters and 1 bar of 94.66 meters are sheared by 574.66 meters as shown in the material flow direction E, 6 bars in the tooth grooves are conveyed to the direction of the alignment roller way in a stepping way by the cooling bed body 3, and the positions of the bars containing non-fixed length in the tooth grooves of the cooling bed body can be determined through detection and tracking.
2. After the rod alignment roller way is aligned, the rod alignment roller way is assembled into multiple-length material layers, each multiple-length material layer is composed of multiple-length rods with a certain number, the multiple-length material layers are conveyed to the conveying roller way 8 through the discharging device 5 of the cooling bed, the multiple-length material layers are sheared into 16-meter fixed-length material layers through the fixed-length cold shears 9, and the fixed-length material layers contain first fixed-length rods 6 with the length of 16 meters and non-fixed-length rods 19 with the length of less than 16 meters (for example, 1 rod with the length of 94.66 meters is sheared into first fixed-length rods 6 with the length of 5 rods with the length of 16 meters and 1 rod 19 with the length of 14.66 meters through the fixed-length cold shears 9).
3. The bars in the sizing material layer are conveyed to the sizing bar separation and collection device 11 through the conveying roller way 8 and transversely move to the conveying chain 21, the sizing bar separation and collection device 11 can collect the first sizing bars 6 sheared by the sizing cold shears 9, and the sizing bar separation and collection device 11 and the conveying roller way 8 are matched to convey the non-sizing bars 19 sheared by the sizing cold shears 9 to the non-sizing bar shearing and sorting collection device, so that the non-sizing bars enter a downstream process.
4. The non-sized bar 19 enters the short-sized conveying roller table 12 of the non-sized bar shearing and sorting device and moves in the arrow C direction in fig. 4 and 6.
5. After the non-fixed-length bar 19 passes through the third lifting baffle 153, the third lifting baffle 153 is lifted, the end face of one end of the non-fixed-length bar 19 is aligned with the third lifting baffle 153 in an abutting mode, the modified-length scissors 16 act to cut the non-fixed-length bar 19 into the second fixed-length bar 20 with the length of 12m, as shown in fig. 5, the left end of the first deflector rod 174 rotates upwards, the left end of the second deflector rod 175 rotates upwards, the third deflector rod 176 does not rotate, the first deflector rod 174 is used for deflector the second fixed-length bar 20 on the short-length conveying roller table 12 to be lifted, and the second fixed-length bar 20 rolls through the first deflector rod 174 and falls into the first modified-length collecting groove 171.
6. The second fixed-length bars 20 after the change of the length are bundled and collected regularly.
The lifting positions and operation methods of the first, second and third lifting baffles 151, 152 and 153 are shown in table 2.
