Special grinding wheel preparation forming equipment for steel rail cutting and forming method of special grinding wheel preparation forming equipment

Abstract

The invention discloses special grinding wheel preparation forming equipment for steel rail cutting and a forming method of the special grinding wheel preparation forming equipment, the forming method uses the forming equipment, and the equipment comprises a machine table unit which comprises a bearing machine table, a driving motor installed on one side of the bearing machine table and a lead screw rotationally arranged on the inner wall of the bearing machine table; the mold unit comprises a mounting box arranged on the inner side of the bearing machine table in a sliding mode and a forming mold arranged above the mounting box; the discharging unit comprises a stock bin and a discharging pipe arranged at the bottom of the stock bin; and the hot pressing unit comprises a hot press body. According to the material guiding device, matched grinding materials are driven by air flow to be guided, meanwhile, the air flow drives the grinding materials to flow, the pushing force generated at the same time enables the material guiding pipe to rotate, so that the grinding materials are more evenly and dispersedly laid in the forming mold, meanwhile, due to the action of the air flow, the interior of the pipeline is not prone to blockage, and the material guiding effect is good.

Description

technical field [0001] The invention relates to the technical field of grinding wheel forming, in particular to a special grinding wheel for rail cutting preparation and forming equipment and a forming method thereof. Background technique [0002] At present, my country's existing railway operation mileage is 100,000 kilometers, high-speed railway is 10,000 kilometers, and urban underground rail transit is 2,750 kilometers. At present, construction is still continued at a high speed. The construction and maintenance of railways require a large number of rail cutting wheels. [0003] In the process of forming the grinding wheel, due to the high wear resistance requirements of the grinding wheel required for rail cutting, the mixing degree of various types of raw materials after the weight ratio is also high, so the raw materials need to be uniform before forming. It is laid flat in the mold, and the existing grinding wheel requires workers to pour the material into the mold b...

AI Technical Summary

Problems solved by technology

[0003] During the forming process of the grinding wheel, due to the high wear resistance requirements of the grinding wheel required for rail cutting, the weight ratio of various types of raw materials is mixed The precision requirement is also high, so it is necessary to evenly spread the raw materials in the mold before forming, and the existing grinding wheel requires workers to pour the material into the mold before forming, and the accumulation of raw materials is too concentrated, so it is necessary to use a scraper Scrape the material in the molding cavity to make it smooth, but in this way, the dispersion of various raw materials is poor and uneven, and the density and flatness of the raw materials are not easy to control, resulting in uneven products after pressing, and the yield rate needs to be improved.
