Stamping elbow problem analysis and low temperature welding method is a pipeline connecting elbow stamping parts, stamping elbow pipe fittings account for a very important position, which also determines its production and has a very strict process Claim. Stamping elbow is a very widely used product, it can be the reason why so extensive that the cost problem is with his inseparable. The stamping elbow transportation costs are also part of the user. 1, the production cost of stamping elbow, a problem has always been subject to the marketplace of ideas, the leading position of stamping elbow with his production cost savings are divided not come. Stamping elbow production does not require a lot of waste material, but does not require too much staff training costs. So stamping elbow on production costs is an advantage of. 2, stamping elbow quality problems, quality stamping elbow can be said is obvious, because of its production process and die, stamping elbow production accuracy can speak is very high. 3, punching elbow market issues, stamping elbow is a widely used product market. It is widely used in place also determines the good market prospects stamping elbow. 4, stamping elbow standard has some relevance, because the stamping elbow application is very broad, so stamping elbow has set performance standards for the industry press elbow in various industries. Soldering method of stamping elbow elbow elbow computerized technology is an important component widely used in various fields industry. Elbow uniform thickness in petroleum, chemical, marine, aviation and nuclear industry has an important purpose, has a special significance in high temperature, high pressure and acid corrosion environment. Once the wall thickness of the plastic molding bend theory and relevant research results by businesses adopt tooling equipment, the production of a large number of bends used in national key construction projects tons ethylene project, tons of high-carbon alcohol engineering, tons of synthetic ammonia project and more petrochemical enterprises. Upon examination, pipe quality than similar foreign products, not only to replace imports, but also exported to Japan, the United States and Southeast Asia, resulting in significant economic and social benefits. The study was to establish a uniform thickness bend molded theory, Jincheng carbon steel elbow, the process parameters are given theoretical basis of design for the application of a new method for the purpose of Heze carbon steel elbow, and develop on this basis appropriate technology, tooling equipment and process parameters CAD systems. When the wall thickness of the pipe bending metal flow patterns and plastic molding mechanism, revealing the process is different from other essential characteristics of pipe bending. Task Force established a hot forming process of bending tube bends forming the constitutive relation and described stress, strain field theoretical model, carbon steel elbow, and experimental verification. Proposed modifications bending strict proportional relationship with the enlarged diameter variations should be kept, that is a function of bending rate and expanding rate. Given the varying curvature of the horns mandrel axis polar equation, it laid the foundation for the horns mandrel exterior design. Bend achieve all computerized process design, the main process parameter control automation, machining technology has changed the elbow lack of theoretical guidance of production status fundamentally. In actual use elbow can fully demonstrate good role and performance, Wu carbon steel elbow, helping industry value and contribution to practical work, bend in the actual production and processing is carried out in accordance with certain processes and process The actual production, to ensure the work life and values.
