Description

Technical Field

[0001] The utility model relates to a tooling hanger, in particular to a tooling hanger used for phosphating the inner and outer surfaces of a gas cylinder. Background Art

[0002] A gas cylinder is a pressure vessel filled with gas. For example, an oxygen cylinder is a high-pressure container for storing and transporting oxygen. Its body is cylindrical and is formed by hot pressing of alloy steel. According to the drawing requirements of the oxygen cylinder product, the inner and outer surfaces of the bottle body need to be phosphated. By immersing the bottle body in the phosphating solution, a layer of water-insoluble crystalline phosphate conversion film (phosphating film) is formed on its inner and outer surfaces to prevent the bottle body from being corroded. A gas cylinder refers to a type of movable pressure vessel with a bottle-shaped main structure, generally filled with gas (which can be compressed gas, liquefied gas, dissolved adsorbed gas, etc.). Gas cylinders are widely used. Whether in the production field or in the life field, they are almost inseparable from gas cylinders.

[0003] When the inner and outer surfaces of oxygen cylinders are phosphated, the suspended bottle body is immersed in the phosphating solution so that the inner cavity of the bottle body is filled with the solution. During the entire phosphating process, the solution in the bottle body must be replaced twice. An oxygen cylinder weighs about 5kg and weighs about 20kg when filled with liquid. If manual liquid replacement is used, not only is the labor intensity high, but there is also a risk of the suspended bottle body falling. In addition, for oxygen cylinders that need to be phosphated in batches, in order to avoid delays in the production cycle and improve work efficiency, it is imperative to innovatively design a tooling hanger that is easy to operate and can complete the phosphating treatment of multiple workpieces at the same time.
