Problems solved by technology

The traditional cooling method is to use a hand-held spray gun to cool the mold, but this method has the following problems: first, the direct use of water spraying method is easy to cause deformation of the mold itself, which leads to the scrapping of the mold and waste; second, the forging process The fine chips or dust generated in the process will stay in the mold due to the treatment of atomized water, which will reduce the quality of the product

Abstract

The invention discloses a cooling device for high-precision gear forging machining. The cooling device comprises a cooling box, a cooling pipe, a circulating oil pump, a cooler, a refrigerating machine and a cooling nozzle; the cooling pipe is arranged on the four walls of the cooling box, one end of the cooling pipe is connected with an inlet of the circulating oil pump, and the other end of the cooling pipe is connected with an outlet of the cooler; one path of cold air generated by the refrigerating machine enters the cooler to cool hot oil, and the other path of the cold air generated by the refrigerating machine is guided into the cooling nozzle arranged on the upper portion of the cooling box; and cold oil cooled by the cooler is conveyed to the cooling pipe to cool a forging mold in the cooling box and then returns to the inlet of the circulating oil pump. According to the cooling device for high-precision gear forging machining, oil indirect cooling and air cooling are simultaneously adopted, and the cooling effect is good; the circulating oil amount can be precisely controlled, so that the cooling temperature is controlled; and the cooling device has the advantages of being good in heat dissipation condition, long in operation cycle, convenient to overhaul and the like.

Description

technical field [0001] The invention relates to the field of gear processing, in particular to a cooling device for high-precision gear forging. Background technique [0002] Nowadays, more precise mechanical gear components are generally produced by forging. The operation process is to use a forging machine for forging, place the workpiece in the forging die, and use the forging hammer of the forging machine to forge. In the forging process, the forging die itself is in a high temperature state due to thermal conductivity. After a forging is completed, the die needs to be cooled. The traditional cooling method is to use a hand-held spray gun to cool the mold, but this method has the following problems: first, the direct use of water spraying method is easy to cause deformation of the mold itself, which leads to the scrapping of the mold and waste; second, the forging process The fine chips or dust generated in the mold will stay in the mold due to the treatment of atomize...
