Description

Technical Field

[0001] The present invention relates to the field of aluminum tube rolling structures, and in particular to an integrated preparation device and method for intelligent heating and rolling of aluminum alloys. Background Art

[0002] Ring rolling machine is a kind of processing machinery for metal ring-shaped workpieces. Ring rolling machine continuously presses plasticity at various positions of the ring-shaped workpiece softened by hot melt by using active rollers and core rollers, reduces the ring thickness of the ring-shaped workpiece, expands the diameter of the ring-shaped workpiece, and controls and changes the cross-sectional shape of the ring-shaped workpiece to form a directional shape. Ring rolling machine has high processing accuracy and high efficiency. The processed product is close to the finished product, which has good use advantages. It requires intelligent heating and rolling integrated preparation equipment and methods for aluminum alloys.

[0003] In the prior art, aluminum alloy intelligent heating and rolling integrated preparation equipment generally includes a heating furnace, with a rolling mill placed on one side of the heating furnace. The aluminum tube is heated by sawing qualified aluminum tubes into segments and placing them in the heating furnace. The heating furnace drives the heated aluminum tubes through a chain in sequence and production rhythm, and automatically slides them onto the working table of the rolling mill. The mandrel is inserted into the hollow tube, and the main shaft roller of the rolling mill is pressed down. After the rolling size is reached, the main shaft roller automatically stops. Finally, the working table automatically rises and supports the rolled aluminum tube, and the mandrel is automatically retracted, so that the aluminum tube can slide onto the ground tray for cooling.

[0046] S1: The hollow aluminum tube is heated by the heating furnace 2. The heated hollow aluminum tube is transported to the feeding rod 32 via the conveying roller 33. The movable plate 26 can be tilted by the feeding mechanism, so that the hollow aluminum tube falls onto the movable plate 26.
