Optiming Researeh On Manufaeturing Process Of Air Brake System To Railway Freight Wagon

The air brake system is of the key Part for railway freight wagon, The level of its manufacturing process will directly affect the safety of railway wagons traffic. This thesis by analyzing the Manufacturing process conditions of CSR Meishan Co., Ltd braking system for railway freight cars, and combined with a more mature and advanced technology of domestic and overseas in recent years, to optimizing the original air brake system manufacturing process.I. Optimization of process equipment. Process equipment will directly affect the level of product manufacturing. According to the Ministry of Railways requirement of the three standardization one interconvert, increased Manipulator to assemble 120 valve module and other equipments, Brake piping system assembly to form a modular system. Through the measure of "use equipment to enhance processes, improve processes to ensure quality", enhance the company’s technological capability.II. Optimization of manufacturing Process for brake piping system. By learning and introducing of new technology, new methods, optimized the method of brake pipe bending、welding process、thread machining and electrostatic spraying technology, achieved specializing production of brake pipe like parts machining and oil painting as well.III. Optimization of assembly process. Through optimizing the assembly process of bottom attachment、the braking system of modular, Promote the assembling quality and processing quality of the brake system on the parts, solve the quality problems of Branch pipe leakage etc.
