[0002] Before wheel rolling, the blank needs to be cut into fixed lengths and sent to a heating furnace for heating.

[0003] At present, the wheel blanks cut into fixed lengths by the disc cold saw in the unloading area are lifted to the top of the chute with a certain slope to the ground by the door crane installed at the disc cold saw discharge port. The wheel blanks slide down the chute to the ground, and the crane operator lifts the wheel blanks to different set ground warehouses according to the wheel product specifications. When rolled to a certain wheel product specification, the crane operator lifts the wheel blanks of this specification in the ground warehouse into the push steel trough next to the heating furnace, and the hydraulic pusher pushes the wheel blank to the side of the heating furnace door.

The present invention delivers the aluminum bars to the bottom of the track support beam by the feed roller, and then the aluminum bar material taking and loading device grabs the aluminum bars from the feed roller and puts them into the transverse trolley, the transverse trolley drives the aluminum bars to move, and the storage grabbing device grabs the aluminum bars and puts them into the rod storage rack for storage, thereby completing the stable clamping and precise transportation of the aluminum bars and improving the storage efficiency of the aluminum bars.
