[0028] Specifically, a first baffle 501 is welded or bolted on both sides of the blanking platform 5, the first baffle 501 is arranged perpendicular to the bar, the distance between the inner sides of the two first baffles 501 is greater than the length of the bar, and one end of the blanking platform 5 is welded Or a second baffle 502 is connected by bolts, both ends of the second baffle 502 are connected to the inner sides of the two first baffles 501, and the second baffle 502 is perpendicular to the first baffle 501. More specifically, the table surface of the blanking platform 5 is arranged obliquely, and the height of the end of the blanking platform 5 provided with the second baffle 502 is lower than the height of the end that is connected with the conveyor belt of the bar sawing device. The blanking platform 5 is inclined to facilitate the automatic rolling of the bar to the second baffle 502.
[0029] Specifically, the pushing device includes a base 1. The base 1 is fixed to the ground with expansion bolts or anchor bolts. A first support 2 is bolted on the base 1.

[0032] When the cut bar material is transported to one end of the conveyor belt, the piston rod of the first hydraulic cylinder 3 of the pushing device extends, driving the push plate 4 to push the bar material on the conveyor belt down the conveyor belt, and the bar material is in the thrust inertia and its own gravity. Under the action, it rolls to the lower end of the blanking platform 5 which is set inclinedly. There are first baffles 501 on both sides of the blanking platform 5 to prevent deviation of the bar during the rolling process. The second baffle 502 blocks the bars; when the number of bars on the blanking platform 5 is sufficient, the piston rod of the second hydraulic cylinder 17 contracts, the electromagnet under the sliding seat 12 is just above the bars, and the piston rod of the third hydraulic cylinder 19 Extend, the electromagnet reduces contact with the bar. Although the blanking platform 5 is tilted, the third hydraulic cylinder 19 and the electromagnet are rotatably connected, and the electromagnet can rotate around the second rotating shaft 21, so the electromagnet can be completely attached to the bar. The electromagnet is energized after the bar is attached, and the electromagnet attracts the bar. Such as figure 2 As shown, the piston rod of the second hydraulic cylinder 17 stretches, pushing the sliding seat 12 to move forward. When the sliding seat 12 reaches the top of the basket 7, the piston rod of the third hydraulic cylinder stretches, and the electromagnet descends. When the iron is powered off, the bar under the electromagnet falls into the material basket 7, then the piston rod of the third hydraulic cylinder 19 contracts, the electromagnet rises, the piston rod of the second hydraulic cylinder 17 contracts, and the slide 12 moves to the blanking platform 5 Above, prepare for the next action. During the moving and unwinding process of the electromagnet, the blanking table 5 has been continuously collecting bar materials to prepare for the electromagnet to attract the materials. After the bars in the basket 7 are full, they are lifted away with a crane, and the empty baskets can be replaced.
