Technical Field
The invention relates to the technical field of railway rail accessory processing, in particular to a method for forming a gauge block.
Background
Railway transportation is widely valued by countries in the world due to large transportation capacity, high efficiency and low transportation cost, and in order to meet the economic development requirements of China, the railway freight of China is rapidly developed in the last decade. Railway transportation is used as a very effective land transportation mode, with the rapid development of economy in China, the construction and traffic mileage of passenger transport and freight transport railways is increased year by year, and new opportunities and challenges are brought to the design and production of railway track fittings.
The gauge block is one of the railway accessories with huge use amount in the current railway line, and is used for adjusting the track gauge of the line by replacing different types of gauge blocks. At present, the existing production modes of the gauge block mainly comprise casting and die forging. Because the gauge block is small in size and large in batch, a large number of sand molds need to be prepared and a pouring gate needs to be arranged before the traditional precision casting process is processed, and the manufacturing is very high because the procedures of cutting, manual polishing and the like are needed after casting. Compared with casting, the die forging method has the advantages that the machining efficiency and the material utilization rate are obviously improved, intermittent production exists, the requirement on the weight of a blank before entering the die is strict, and meanwhile, the die manufacturing and replacing cost is high. Therefore, a new method for forming the gauge block is needed.
