Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with specific examples, and the following examples are only descriptive, not limiting, and cannot limit the protection scope of the present invention with this.

[0028] A method for manufacturing cold-drawn gas cylinder tubes for medical oxygen cylinders, the production process is as follows:

[0029]

[0030] The cold drawing deformation process route of the present invention is:

[0031]

[0032] According to the design of the cold drawing deformation process, the geometric dimensions of the inner and outer molds of each deformation pass are selected, and the geometric dimensions and surface quality of the in-process and finished pipes of each pass are well controlled.

[0033] Concrete process steps are:

[0034] (1) Incoming inspection of hot-rolled raw material pipes

[0035] Select the raw material tube specification according to the finished product specification, determine th...

Abstract

The invention relates to a method for manufacturing a cold-drawing gas cylinder tube for a medical oxygen cylinder. The method comprises the following steps of: (1) performing incoming inspection on a hot-rolling raw material tube; (2) performing acid cleaning and lubrication on the raw material tube; (3) performing cold drawing for the first pass; (4) performing annealing on a product tube; (5) performing acid cleaning and lubrication on the product tube; (6) performing cold drawing for the second pass; (7) performing annealing on the product tube; (8) performing acid cleaning and lubrication on the product tube; and (9) performing cold drawing for the finished product pass. The cold-drawing gas cylinder tube manufactured by the method has a thick and uniform wall and high physical and chemical properties, and the product is safe and reliable and is exclusively produced for the first time at home. All performance of the steel tube comprehensively meets technical requirements of users, and the cold-drawing gas cylinder tube has an extensive market prospect.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, relates to a medical oxygen cylinder, in particular to a method for manufacturing a cold-drawn gas cylinder tube for a medical oxygen cylinder. Background technique [0002] Traditional medical oxygen cylinders are stamped and formed by billet and then drawn to the specified size.
