Description

【Technical field】 [0001] The invention relates to a closing process of a gas cylinder, more specifically, the invention relates to a reverse closing process of a seamless gas cylinder and an aluminum alloy seamless inner lining. 【Background technique】 [0002] Aluminum alloy seamless gas cylinders and aluminum alloy seamless linings (lining of aluminum-based fiber-reinforced high-pressure composite containers) can achieve seamless closing and no welding structure, which greatly reduces the risk of welding seams and greatly improves Reliability and significantly lower weight than traditional steel welded gas cylinders. However, the original traditional gas cylinders in my country, such as Class I and II pressure vessels, are made of ordinary steel or stainless steel, and are of welded structure. Corrosive gases will cause serious corrosion to the container, and the weld structure will also cause loss to some gases. adsorption. Therefore, some special gases or corrosive gases...

Problems solved by technology

Among them, due to the use of rotary wheels to extrude the material flow on the surface of the workpiece, the forward rotation is prone to interlayer separation, resulting in delamination defects, which affects the safety performance of the product; secondly, there are more closing plates, at least 10 times, so Closing is slow, there are about 50 single machines per day, and its closing efficiency is low. In addition, because of the large number of closing plates, it takes a long time to heat up. Ablation, the quality of the inner surface is not high, which affects the material performance and reduces the safety performance

And another kind of compression forming, the workpiece is extruded according to the mold by extrusion, because the deformation of the product is too fast in one extrusion, it is easy to have defects such as accumulation of the mouth after closing, bottle body bending, etc., and the closing effect is not ideal; secondly. , one-time extrusion molding, the compression itself is fast, but it needs to be equipped with auxiliary heating equipment and extrusion equipment, and multiple people are required to divide the work. The demand for manpower and material resources increases. The daily single machine is about 70 to 120 pieces. The efficiency is not high; finally, because of the instant extrusion molding of the closure, the deformation is too fast, and it is easy to form wrinkles on the inner surface, so that weak points appear along the wrinkles, affecting the safety performance of the product, posing safety hazards, and cannot be filled with special gases
