Embodiment Construction
[0057] Attached below Figure 1-7 Specific embodiments of the invention are described.
[0058] The following examples facilitate a better understanding of the invention, but do not limit the invention. The following embodiments are only some of the embodiments of the invention, but not all of them. The components and materials used in the following examples are commercially available unless otherwise specified.
[0059] The automatic lubricating and cooling method of the rail heel forging die is characterized in that it comprises the following steps:
[0060] Step S1, the automatic lubrication and cooling system starts and operates;
[0061] In the above embodiment, further: in the step S1, after the rail parts are released from the mold and the reheating system starts to work, the trolley traverses to the position of the column of the press, and is automatically lubricated according to the temperature of different parts of the mold, the length of the mold, and the size of...

The invention provides an automatic lubricating and cooling method and system for a steel rail heel end forging and pressing die. The automatic lubricating and cooling method comprises the following steps that S1, the automatic lubricating and cooling system is started and works; S2, a rail piece surface oxide and die cavity cleaning system is started and operates; S3, the automatic lubricating and cooling system retreats from a station, and a forging and pressing system is started and operates; S4, the forging and pressing system completes operation, and the automatic lubricating and cooling system is restarted and operates; and S5, the steps from S1 to S4 are circulated in a reciprocating manner till steel rail heel end forging and pressing production is completed. The method has the characteristics of completeness, reliability, autonomous quality control and programmed operation of lubricating key operation parts; good metal flowing conditions are achieved, good and stable operation of the system can be guaranteed, and forging and pressing quality is guaranteed; due to manual and automatic duplex control, effective and reliable lubrication is guaranteed; the micro-lubrication operation is synchronized while continuous cooling is realized; and cooling and lubricating are reasonably combined, operation consumption in the cooling and lubricating process is optimized, and energy conservation and consumption reduction are remarkable.
Description
technical field [0001] The invention belongs to the technical field of lubrication and cooling, and in particular relates to an automatic lubrication and cooling method and system for a rail heel forging die. Background technique [0002] Rail heel forging is a high-temperature forging process that heats and die-forges one cross-section rail into another cross-section rail. It is a complex and special operation under high-temperature and high-pressure operating conditions in the entire turnout processing and production. process. From the perspective of technology, in addition to pressure and temperature, the state of the mold has a decisive influence on the forging process and quality of rail parts. Among them, the mold state mainly involves two aspects: the mold temperature and the lubrication state of the mold surface. In daily production, the mold temperature should be controlled within a reasonable range. Continuous operation molds often have insufficient cooling meas...
