The invention provides a double-moving-table machining method based on two-station press machine steel rail heel end profiling and upsetting. A moving table II is additionally arranged in an existing press machine two-station heel end profiling production line, and an original moving table I is still used for steel rail heel end daily production; and the newly-added moving table II is used for steel rail upsetting operation, and steel rail heel end profiling and upsetting machining production of one two-station press machine is achieved. According to the method, by means of the manner that the moving table is additionally arranged in the existing 5000-ton press machine two-station heel end profiling production line, steel rail heel end production is still conducted through the original moving table, and the newly-arranged moving table is used for upsetting operation; and the structure is reasonable, simple and practical, universality is high, mounting and maintenance are convenient, and the method is suitable for a steel rail turnout precision forging process production line and capable of being widely applied to the field of steel rail piece heel end forging.
Description
technical field [0001] The invention belongs to the technical field of rail heel end production, and in particular relates to a rail heel end profiling and upsetting double-moving processing method based on a two-station press. Background technique [0002] The rail pier roughing process has been used in the rail pressing process for many years. For a long time, the method of segmented heating and segmental pier roughing has been adopted. The length of each heating and pier thickening is generally 120mm. The rail heel forging is realized by heating the pier multiple times. Pier roughing process with a length range of 1000mm. [0003] In recent years, a new process method has emerged that can realize the overall pier thickness within 1000mm of the heel end of the rail. This process is easy to operate, more reliable and more efficient. In each turnout manufacturing unit, the application of the new pier roughing process, especially the application process of the 5,000-ton pres...
