Preparation method of precision casting wax for casting train wheel node base

Abstract

The invention discloses a preparation method of precision casting wax for casting a train wheel node base and relates to the technical field of precision casting. The casting wax is prepared from the following raw materials in parts by weight: 10-20 parts of stearic acid, 8-10 parts of ozocerite, 15-25 parts of paraffin, 5-7 parts of white carbon black, 3-5 parts of Vaseline, 10-20 parts of bee wax, 15-17 parts of vegetable wax, 6-8 parts of microcrystalline wax, 3-5 parts of modified silica sol, 5-7 parts of water glass, 2-4 parts of quartz powder and 2-4 parts of an adhesive. The preparation method has the beneficial effects of being novel in design, reasonable in formula and scientific and normative in preparation technology; in practical preparation, the actual viscosity of the casting wax is fully and effectively achieved, the traceless performance of a wax mold prepared from the casting wax can be achieved while the smooth performance of the wax mold is ensured, and the precision performance and high quality of a casting part are ensured.

Description

technical field [0001] The invention relates to the technical field of precision casting, in particular to a method for preparing precision casting wax for casting train wheel node seats. Background technique [0002] Vehicles running on railway tracks, usually composed of multiple carriages, are the most important machines in human history. In the early days, they were called steam locomotives, and they ran on independent tracks. Railway trains can be divided into freight wagons and passenger wagons according to the load, and there are also passenger wagons with both. [0003] Because the train is a huge means of transportation, the wheel system is the most important component system in its actual use. In normal use, it bears the most serious pressure and wear. The node seat is the main link connecting the wheels of the train. One of the components, the rationality of its design is usually a reference for evaluating the quality of the train wheel system. Due to its applica...

[0003] Because the train is a huge means of transportation, the wheel system is the most important component system in its actual use. In normal use, it bears the most serious pressure and wear. The node seat is the main link connecting the wheels of the train. One of the components, the rationality of its design is usually a reference for evaluating the quality of the train wheel system. Due to its application area, the structure of the node seat is relatively complicated, so it is easy to break at each node. Therefore, in actual casting, it must be To ensure the actual precision performance of the workpiece, for such precision parts, if ordinary casting wax is used, there will usually be great disadvantages, resulting in certain flaws in the cast node seat, resulting in poor performance of the node seat , there will be immeasurable safety hazards in serious cases
