Problems solved by technology

Poor manufacturing process will cause the wall thickness difference of the container bottle to be too large, and the quality difference of the whole gas cylinder is very large. Similarly, if the temperature control is not good when the bottom is closed by hot spinning in the mass production process, the bottom of the gas cylinder will be damaged. Air leakage, leaving a major safety hazard

Embodiment Construction

[0018] The present invention will be further described below through specific examples.

[0019] A thermal deep drawing process for a titanium steel cylinder is characterized in that it comprises the following steps:

[0020] Material selection: choose titanium plate as the blank, calculate the size according to the size of the steel cylinder, and then use a cutting machine to cut the blank into circular plates according to the calculated target size;

[0021] Mold fixing: select the hot drawing mold according to the cut circular plate, the mold has at least three mold positions with successively deeper depths, fix the mold on the clamping machine, and clean the mold;

[0022] Mold test: Use aluminum material with relatively cheap price and good processing performance as the experimental material, use the mold for experimental processing, and check whether the mold can be processed;

[0023] Annealing: place the cut circular plate in an annealing furnace for annealing treatme...

Abstract

The invention discloses a titanium steel cylinder hot drawing process which includes the steps of material selecting, mold fixing, mold testing, annealing, grinding, drawing, shell nosing, cleaning and the like. Primary hot drawing is conducted on a ground blank material, solution treatment is conducted after primary hot drawing, secondary hot drawing is conducted, tertiary hot drawing and correcting are conducted on a blank where secondary hot drawing is conducted, and pressure maintaining is conducted during the tertiary hot drawing and correcting. By means of multiple times of drawing and solution treatment, the overall quality of a steel cylinder is ensured.

Description

technical field [0001] The invention relates to the technical field of gas cylinder processing, in particular to a thermal deep drawing process for a titanium steel cylinder. Background technique [0002] As a clean energy source, natural gas is widely used in various fields, and plays an important role in both life and production. Correspondingly, the development of pressure vessels filled with compressed natural gas is particularly necessary. Due to the flammable and explosive characteristics of natural gas, the requirements for the airtightness of the containers are very high. Poor manufacturing process will cause the wall thickness difference of the container bottle to be too large, and the quality difference of the whole gas cylinder is very large. Similarly, if the temperature control is not good when the bottom is closed by hot spinning in the mass production process, the bottom of the gas cylinder will be damaged. Leakage, leaving a major safety hazard. Contents o...
