Description

Technical Field

[0001] This utility model relates to the field of seamless gas cylinder processing technology, specifically a fixing device for the necking of a seamless gas cylinder. Background Technology

[0002] Seamless gas cylinders are high-pressure containers formed by integral forging or extrusion without weld seams. They are widely used in industrial gas storage, medical devices, energy transportation and other fields. Due to their strong structural integrity and excellent high-pressure resistance, they can effectively avoid safety hazards caused by weld fatigue and are key equipment for high-pressure gas storage. In the production process of seamless gas cylinders, the necking process is a crucial step. This process shapes and narrows the gas cylinder's end to form a structure that meets sealing requirements, laying the foundation for subsequent valve installation and airtightness testing. The quality of the necking directly affects the gas cylinder's sealing performance and overall safety. Insufficient processing precision may lead to problems such as gas leakage and reduced pressure resistance. Seamless gas cylinder necking devices on the market have poor stability during use. During processing, vibration and positioning deviation can easily lead to insufficient necking dimensional accuracy, affecting product consistency. In addition, the existing devices have fixed fixture structures, which are difficult to adapt to gas cylinder models with a certain diameter range. Frequent fixture changes are required, which not only increases production time and costs but also reduces processing efficiency, failing to meet diverse production needs. Utility Model Content
