Description

Technical Field

[0001] This invention relates to the field of gas cylinder processing technology, specifically a dual-station gas cylinder mouth processing production line. Background Technology

[0002] Aluminum gas cylinders are pressure vessels used to store extinguishing agents. They are lightweight and corrosion-resistant, weighing approximately 40% less than traditional steel cylinders, making them easier to carry and handle, especially suitable for portable fire extinguishers. Furthermore, aluminum cylinders have excellent corrosion resistance, are not prone to rust, effectively extending their service life and reducing maintenance costs. In addition, aluminum cylinders are non-magnetic, unaffected by certain special environments.

[0003] Currently, aluminum gas cylinders are typically machined using automatic lathes for the neck. While this method is efficient, manual loading and unloading are still required. After machining, the cylinders must be unloaded from the workstation and placed on a shelf before new cylinders are installed. The lathe takes a considerable amount of time to operate, and logistics are needed for stacking and transporting the cylinders. Although aluminum cylinders are lightweight and easy to handle, they are also soft and cannot be dropped. Workers must bend over to pick up and put down cylinders at the bottom of the shelf, which not only increases the intensity of manual labor but also increases the actual processing time and reduces overall efficiency. Therefore, a solution is needed. Summary of the Invention
