Problems solved by technology

[0004] The purpose of the present invention is aimed at domestic periodic furnaces with unstable normalizing quality of bolsters and side frames, low thermal efficiency, poor working conditions and high energy consumption of foreign catenary-type bolsters and side frame normalizing production lines, high failure rate of dropped parts, and low furnace temperature. Insufficiencies such as unevenness and limited heating methods provide a self-developed rail car bolster side frame continuous push plate heat treatment production line

Abstract

The invention discloses a rail locomotive bolster lateral frame continuous pushing-disc type heat treatment production line comprising at least one normalizing furnace, a normalizing furnace oil cylinder material-pushing machine arranged at a feeding end of the normalizing furnace, a normalizing furnace oil cylinder material-pulling machine arranged at a discharge end of the normalizing furnace, a forced cooling chamber, a forced cooling chamber oil cylinder material-pushing machine arranged at a feeding end of the forced cooling chamber, a slow cooling chamber communicated with a discharge end of the forced cooling chamber, a discharge support connected with a discharge end of the slow cooling chamber, a hanging beam arranged above the discharge support, and a material-pulling machine arranged at an outlet end of the discharge support. A material conveying device comprises a first guide rail, a second guide rail, a small transporting car, and a drive motor, wherein the small transporting car is arranged on the first guide rail and the second guide rail, and can move along the first guide rail and the second guide rail. The production line has the advantages of lowering thermal energy consumption, providing stable and high-quality bolsters and lateral frames, reducing rejection rate, lowering cost of enterprises, improving economic benefits of the enterprises, and being stable in product quality, and reliable and stable in performance.

Description

technical field [0001] The invention relates to a continuous push plate type heat treatment production line for rail vehicle bolster side frames. Background technique [0002] At present, the normalizing heat treatment of rail transit train bolsters and side frames in China adopts periodic normalizing furnaces 20, such as trolley furnaces and box furnaces. Due to the large volume of bolsters and side frames, the weight of a single unit is more than 800 kg. , the placement of bolsters and side frames is fixed, the temperature field in the periodic furnace is uneven, and the heating of bolsters and side frames is uneven, which will increase the fluctuation of heat treatment quality of bolsters and side frames, increase the scrap rate, and affect Business efficiency. Simultaneously cycle normalizing furnace 20 has heated bolster and side frame and needs to manually carry it on the cooling platform for cooling, and the cooling transfer time can only be grasped by the experience...
