Description

Technical Field

[0001] The present invention relates to the field of aluminum material production, and in particular to a double-traction device and method for unloading aluminum bars. Background Art

[0002] Aluminum products are made from aluminum and other alloying elements. They are typically processed into castings, forgings, foils, plates, strips, tubes, bars, and profiles, followed by cold bending, sawing, drilling, assembly, and coloring. Aluminum bar is a type of aluminum product. Its production includes melting, purification, impurity removal, degassing, slag removal, and casting.

[0003] After the aluminum rod is output from the forming equipment, it needs to be cut into segments according to specific length specifications. This process is usually completed on a tractor. The tractor drags the front end of the aluminum rod, moves it to the cutting equipment for cutting, and then continues to drag the aluminum rod forward for a distance before unloading the cut aluminum rod from the tractor.

[0004] Patent publication number CN211193070U discloses an automatic dual-pulling machine for aluminum profiles. Two traction mechanisms alternately pull aluminum profiles, accelerating production time and improving efficiency. Existing aluminum bar unloading devices generally have a single function and fail to achieve dust reduction, thus requiring improvement.

[0005] To this end, we propose a double-traction device and method for aluminum bar blanking. Summary of the Invention

Adjust the heights of the material receiving assembly (3) and the material cutting assembly (6) according to the use requirements; A second electric cylinder is fixedly connected to the inner wall of the bottom end of the base (11), and the bottom end of the push rod (15) passes through the base (11) and is connected to the top end of the second electric cylinder. The second electric cylinder adjusts the exhaust plate (16) and the cross bar (17) to a suitable height through the push rod (15); The motor (41) drives the threaded rod (40) to rotate, and the threaded rod (40) cooperates with the thread of the movable plate (42), so that the movable plate (42) can push the support plate (36) upward through the push rod (39), and then push the receiving rod (34) upward until the receiving rod (34) is pushed to a specified height, and the aluminum rod body can be moved onto the receiving rod (34); S3, lay the prepared aluminum bars flat on the material rack → then heat the aluminum bars → keep the temperature at 480℃ for 1 hour → heat the mold to 480℃ → put the mold into the mold base → send it to the raw material outlet → extrude → wait for the extruded aluminum profile to come out of the material outlet → pull it to the cutting assembly (6) by the first tractor (4) for cutting → the cut aluminum profile → pull it to the receiving assembly (3) by the second tractor (5) for temporary storage; When the cutting assembly (6) is working, the exhaust fan starts to work, and the exhaust fan exhausts air to the collection box (9) through the exhaust hose (27). The collection box (9) exhausts air toward the exhaust plate (16) and the cross bar (17) through the through hole (23) and the connecting pipe (20), respectively, so that the dust generated when the cutting assembly (6) cuts materials can be sucked into the first exhaust chamber (18) and the second exhaust chamber (21). The dust entering the first exhaust chamber (18) and the second exhaust chamber (21) can enter the drawer (13) located in the slot (24) through the through hole (23). The filter plate (28) located in the drawer (13) can filter the dust entering the drawer (13).
