Abstract

The invention relates to a workblank forging air cooling process, in particular to a workblank forging air cooling process for a non-quenched and tempered automobile engine connecting rod. The invention also relates to air cooling equipment adopted for implementing the air cooling process. The air cooling equipment comprises a system machine frame, a transmission chain, an air tube, a blast blower and a computer control device. The forge element cooling speed is precisely controlled through the air cooling equipment, the equipment can realize the computer automatic programming control, and the chain speed and the air outlet quantity of each air cooling passage can be regulated according to different air cooling requirements of the forge elements, so the hardness and the metallographic structure of the forge elements reach the standard requirements. The process and the equipment provided by the invention belong to the workblank forging air cooling process for the automobile engine connecting rod and the air cooling equipment with the advantages that the structure is simple and reasonable, the operation is convenient, the cooling speed of the forge elements can be effectively controlled, and meanwhile, the quality of the forge elements can be ensured.

Description

technical field [0001] The invention relates to a blank forging air-cooling process, in particular to a non-quenched and tempered automobile engine connecting rod blank forging air-cooling process, and the invention also relates to the air-cooling equipment used for implementing the above-mentioned air-cooling process. Background technique [0002] The forging process generally consists of the following processes, namely blanking, heating, forming, cooling after forging, pickling and heat treatment after forging. The post-forging cooling process is an important step in the forging process. If the process is improper, it may cause cooling cracks, white spots, and network carbides. Improper cooling after forging will warp the forging, increase the surface hardness, and even cause cracks, making the forging scrap. Therefore, the correct cooling of forgings after forging is a very important process in the forging process. After the non-quenched and tempered automobile engine ...
