Precision forging process production line for steel rail turnout

Abstract

The invention relates to a precision forging process production line for a steel rail turnout, which is characterized in that the precision forging process production line comprises a steel rail turnout precision forging press, a heating furnace, a normalizing furnace, a steel rail forward conveying device, an automatic steel rail feeding mechanism and an automatic steel rail blanking mechanism; a steel rail transversely-conveying trolley is arranged between the automatic steel rail feeding mechanism and the automatic steel rail blanking mechanism; a transversal motion guide rail and a transmission gear rack are arranged under the steel rail transversely-conveying trolley; a plurality of steel rail precision feeding devices and a servomotor are arranged on the steel rail transversely-conveying trolley; and an electric cabinet used for controlling the operation of the whole production line is arranged on the outer side of the automatic steel rail feeding mechanism. The precision forging process production line has the advantages as follows: the production line is suitable for hot compression molding technology of various AT (abbreviation for Pinyin of 'short-type cross section') steel rail turnouts, and all devices and mechanisms of the production line can achieve automation control without manual intervention, so that time and labor are saved, the labor intensity of operators is reduced, the processing period of the steel rail turnout is shortened, the production cost is lowered, the machining precision and the qualification rate of the steel rail are improved, and the requirement of high-quality steel rail can be satisfied further.

Description

technical field [0001] The invention belongs to the technical field of forging processing equipment for steel rails, and in particular relates to a production line for precise forging of steel rail forks. Background technique [0002] The construction of high-speed railways has an important impact on the development of the national economy. With the emergence of high-speed trains, the demand for rails is increasing, and the requirements for forging precision and quality of rails are also getting higher and higher. At present, the forging and pressing equipment used for steel track turnout mainly adopts three-beam and four-column hydraulic press, and the pressing is formed into a hot mold pressing process with one mold, front and rear double stations. The raw materials are pressed many times. The disadvantages of the traditional steel track turnout pressing equipment are that the upper and lower sequences of the equipment are completed manually with the crane, the efficiency ...

AI Technical Summary

Problems solved by technology

Since there is no positioning device for the rails during the conveying process, the existing feeding equipment must be manually intervened to send the rail workpieces to be processed to the hydraulic press, which not only leads to inaccurate positioning of the rails to be processed, but also reduces the scrap rate. High; and it is time-consuming and labor-intensive, the processing cycle of the rail is long, and the cost is high
