The principle of metal spinning process is to cover the processed metal blank (tube blank) on the mandrel, while the blank is pressed at the end of the mandrel by the tail, and rotates with the mandrel along the spindle, and the rotary wheel moves along the mandrel.

The China International Fluid Machinery Exhibition, which has been successfully held for three times, is sponsored by China General Machinery Industry Association. It is understood that the total exhibition scale of this exhibition will reach 3,000 square meters. More than 60 world-class companies such as General Electric, Siemens Germany, and Bergman Germany, as well as more than 300 domestic fluid machinery manufacturers will participate. The exhibition will also hold the second international valve technology development forum and the third international fan and compressor technology development forum. According to the organizer, many companies will display their advanced products and technologies in a large area and highlight their corporate culture and business philosophy. Among them, the new Shengu Group set a floor space of 300 square meters to create the largest number of individual enterprises participating in the exhibition; Shaanxi Drum Group set a maximum of 200 square meters of exhibition space to create the most unique products for the exhibition. The president of China General Machinery Industry Association Yan Yongbin said: “This exhibition will be a large one with a large area, high level, and many exhibitors. We will innovate in terms of layout, reception, etc. We will strive to be perfect.â€
It is understood that China's fluid machinery manufacturing industry has formed an industrial system that integrates design, manufacturing, scientific research, teaching, and technical services. The economic scale has developed at a rate of around 30% per year in the past five years. In 2007, there were more than 4,000 enterprises above designated size, and the total industrial output value was over RMB 300 billion. At the same time, through scientific and technological research, digestion and absorption of imported technology and technological transformation, the independent innovation capability and market competitiveness of China's fluid machinery manufacturing industry have been significantly improved. Has the ability to supply large-scale oil pumps, large-scale centrifugal compressors, and large-diameter valves for long-distance pipelines for oil and gas, and the ability to provide key fluid mechanical products such as large-scale blast furnace blowers, sintering fans, and various pump valves for steel companies; It has the ability to provide key fluid mechanical products such as pumps, blower fans, and nuclear grade pumps and valves for power plants with 600,000 to 1 million kilowatts of supercritical and ultra-supercritical thermal power, and millions of kilowatts of pressurized water reactor nuclear power. The Deputy Director of Energy Conservation and Technology Equipment Division of Energy Development Bureau of the National Development and Reform Commission told reporters: “We have always been committed to promoting the localization of energy technologies, and fluid machinery is of vital importance here.â€
Yan Yongbin said: "With the rapid development of the national economy, the fluid machinery manufacturing industry has made many new breakthroughs in independent innovation. It has developed millions of tons of ethylene, three crackers, and 50,000 to 60,000 cubic meters of air separation plants. With a large number of large-scale axial compressors and other major technical equipment, we have too many things to show.â€
Generally speaking, light automatic spinning machines have structural advantages similar to ordinary lathes. However, in order to meet the requirements of the above spinning process, large spinning machines usually have the following 11 core advantages.
1. The automatic spinning machine bed, main shaft, and transmission system, rotating wheel frame, tailstock and other parts should have sufficient rigidity, and also have a heavier worktable, a thicker guide rail, and a thick wall bearing support And cabinets.
2. The horizontal and longitudinal feed mechanisms of the rotary frame are mostly driven by hydraulic transmission or a combination of mechanical and hydraulic pressure to generate sufficient spinning pressure and balance step-less speed regulation to meet process requirements.
3. Ordinary automatic spinning machines usually use one rotary wheel, but there are multiple auxiliary forming wheels (flanging wheel, curling wheel, etc.). The number of rotating wheels or rotating frame of the powerful automatic spinning machine is 2 to 3 (the general type is 2, and the cylindrical part spinning machine is mostly 2 to 3), and is symmetrical to the spindle axis. Balancing the radial force during spinning, reducing the bending deflection, deflection, and vibration of the spindle and core mold provides a prerequisite for improving the accuracy of spinning parts. This correspondingly requires the rotary wheel to have a higher horizontal (such as a special spinning machine for cylindrical parts) or a longitudinal (such as a general-purpose automatic spinning machine) synchronous feed accuracy. However, a rotary wheel is used for the light and powerful automatic spinning machine.
4. The main shaft has sufficient transmission torque and power. According to the specific process requirements, it can meet the constant torque or constant power adjustment. In addition, it is best to make the spindle speed and the longitudinal feed speed of the rotary wheel steplessly adjustable. On the one hand, it can meet the arbitrary selection requirements of the spinning process; on the other hand, it can maintain the surface rotation speed of the core mold during the spinning process. Possibility of constant feed per revolution.
International Fluid Show Opening
From October 28 to 30, the Fourth China International Fluid Machinery Exhibition will be held at the China International Exhibition Center in Beijing. The theme of the exhibition will be “Energy Conservation, Environmental Protection, Harmony, and Developmentâ€. The exhibition will show the latest technology and development trends of the fluid machinery industry to the entire industry.
