Description

Technical Field

[0001] The invention relates to the technical field of aluminum processing equipment, and in particular to an aluminum rod pushing and placing device. Background Art

[0002] Currently, aluminum tube cutting still commonly relies on manual handheld cutting. Operators must manually grip the aluminum tube and secure it to the cutting equipment, effectively cutting only a single tube at a time. This method is not only labor-intensive but also subject to subjective factors such as operator experience and fatigue. Cutting accuracy is difficult to guarantee and is prone to problems such as burrs and length errors. Furthermore, manual operation is extremely inefficient and cannot meet the demands of large-scale production. Frequent contact with the cutting equipment poses safety risks such as tool scratches and flying debris, posing a high occupational health risk.

[0003] To improve production efficiency, some companies have introduced belt conveyors to assist in aluminum tube cutting, transporting the tubes to the cutting station via belts. However, this method still has significant drawbacks: First, it lacks precise positioning and height adjustment capabilities, and the tubes are prone to shifting and rolling during transportation, resulting in deviations in the cutting position and increased scrap rates. Second, batch cutting is impossible, and manual counting and sequencing of the tubes is required. This is not only time-consuming and labor-intensive, but also prone to counting errors, affecting the accuracy and timeliness of product delivery. Third, existing equipment is difficult to adapt to different specifications of aluminum tubes. When the product size or length changes, the equipment needs to be readjusted or accessories replaced, which reduces flexibility and increases equipment commissioning costs. Summary of the Invention
