Background
The driving and driven gears of the automobile are generally manufactured in a forging mode, a blank before the driving and driven gears are forged needs to be subjected to preliminary heat treatment, and the preliminary heat treatment effect has great influence on cutting processability and the final heat treatment deformation condition. In order to ensure that the machinability of the gear blank is improved, forging stress is eliminated, the structure is homogenized, and the prior heat treatment is generally carried out in an isothermal normalizing mode and the treatment is generally carried out by adopting a push rod type isothermal normalizing furnace in the field. However, in the conventional push rod type isothermal normalizing furnace, since it is difficult to control the cooling rate of the normalizing after normalizing the carburized steel forging blank, the austenite decomposition transformation cannot be controlled and is necessarily continuously performed in one temperature range, and thus the obtained microstructure and hardness may be different. For steel parts with higher cooling speed, unbalanced structures can be obtained partially or even completely, so that the cutting performance can be affected, the deformation rule of the steel parts after carburizing and quenching can be changed, and the steel parts are deformed too much to be scrapped. For steel parts with slower cooling speed, the hardness of the steel is too low, so that plastic deformation is easy to occur during cutting, cutting burrs are formed, and the phenomena of sticking and burning of the cutter are generated. In order to improve the effect of the high isothermal normalizing treatment, the normalizing furnace and the rapid cooling chamber are in butt joint for treatment, and a height difference exists between the normalizing furnace and the rapid cooling chamber.
For the driving gear and the driven gear with larger mass, the driving gear and the driven gear are easy to damage the conveying belt of the quick cooling chamber when being conveyed between the normalizing heating furnace and the quick cooling chamber, so that a device arranged between the normalizing heating furnace and the quick cooling chamber for buffering workpieces is needed to prevent the workpieces from falling to damage the conveying belt of the quick cooling chamber, prolong the service life of a production line and reduce the production cost.
