The cylinder top and bottom machine is a key equipment in the field of cylinder manufacturing. It is mainly used for the molding and processing of the top and bottom of the cylinder. Its technical characteristics, application scenarios and development trends are as follows: 1. Equipment function and core function. Forming processing. Through mechanical pressure or spinning process, the top and bottom of the cylinder are processed into shapes that meet the design requirements (such as hemispherical, flat bottom, etc.), ensuring the sealing and structural strength of the cylinder. Process accuracy control equipment must have high-precision processing capabilities to ensure that the dimensional tolerance and surface finish of the cylinder top and bottom meet industry standards (such as GB/T 5099, ISO 11120, etc.). Material adaptability is suitable for cylinder processing of various materials such as carbon steel, stainless steel, aluminum alloy, etc., to meet the needs of different industries (such as industrial gas, fire protection, medical care, etc.). 2. Technical features and classification: Stamping top and bottom machine: Through mold stamping molding, it is suitable for mass production, with high efficiency but high mold cost. Spinning top and bottom machine: gradual extrusion molding through rotating wheels, high flexibility, suitable for small batches or multiple varieties of production. Semi-automatic equipment: manual loading and unloading, suitable for small and medium-sized enterprises. Fully automatic production line: integrated loading and unloading, forming, inspection and other links, suitable for large-scale production. Key technical parameters Pressure range: usually from hundreds to thousands of tons, depending on the cylinder specifications and material. Processing accuracy: The thickness deviation of the top and bottom is ≤±0.5mm, and the surface roughness Ra≤3.2μm. Production efficiency: A single device can process 10-50 cylinders per hour (depending on process and specifications). 3. Application scenarios and industry demands. The industrial gas field is used to manufacture storage cylinders for industrial gases such as oxygen, nitrogen, and argon, which require high strength and corrosion resistance. The production of cylinders for fire respirators in the fire protection and emergency field must meet the needs of lightweight, high-strength and fast filling. The manufacturing of medical oxygen cylinders or food-grade gas cylinders in the medical and food fields must comply with hygiene standards such as GMP or FDA. New energy and special gases such as hydrogen cylinders, high-purity gas cylinders, etc. have higher requirements for materials and processes. 4. Market status and development trends. Market size. The global cylinder top and bottom machine market is expected to grow by about 5%-8%. The main driving factors include the growth of industrial gas demand and the expansion of the new energy field. Intelligent technology development trends: Integrate AI visual inspection and adaptive control systems to improve processing accuracy and efficiency. Energy-saving and environmentally friendly: Use servo motors and hydraulic energy-saving technologies to reduce energy consumption. Modular design: easy to upgrade and maintain equipment and adapt to the production needs of multiple varieties. The main suppliers of the competitive landscape are concentrated in Germany, the United States, China and other places. Domestic companies such as Zhejiang Wanrun Heavy Industry have advantages in cost-effectiveness and localized services. 5. Selection recommendations are recommended to select small batch production based on the production scale: spin-pressed semi-automatic equipment is recommended, with high flexibility. Large-scale production: It is recommended to choose a fully automatic production line to improve efficiency. Pay attention to equipment compatibility to ensure that the equipment is compatible with cylinders of different materials and specifications.
