The invention relates to a cold heading device for metal machining. The cold heading device comprises a cold heading machine, a cooling mechanism and a closed machine shell, wherein a cooling chamberis formed in the machine shell; the cold heading machine carries out cold heading machining on a metal bar in the cooling chamber, and the cooling mechanism comprises a refrigerator, the refrigeratingchamber, an output pipeline, a rotational flow blowing nozzle, an air compressor, a moisture absorber and a backflow pipeline; the refrigerator is cylindrical, and the cross section of the refrigerating chamber is also circular; one or more heat exchange blades are fixedly arranged on the peripheral face of the refrigerator; and the refrigerating chamber, the output pipeline, the rotational flowblowing nozzle, the cooling chamber and the backflow pipeline sequentially communicate end to end to form a closed circulation loop. According to the cold heading device, gas serves as a heat exchangemedium, the flow speed is high, the impact on a die is small, meanwhile, the gas can make direct contact with all the outer surfaces of the interior and the exterior of the die to realize timely andrapid heat exchange, so that the temperature difference of all parts of the die is reduced, then the stress caused by the temperature difference in a product can be eliminated to the maximum extent, and finally, the performance and quality of the product are guaranteed.
Description
technical field [0001] The invention relates to the field of cold heading equipment, in particular to a cold heading device for metal processing with low humidity and cooling. Background technique [0002] Cold heading is a forging method that uses a mold to upset a metal bar at room temperature. It is usually used to manufacture the heads of screws, bolts, rivets, etc. The cold heading mold is one male and one female. The cold heading process is used to manufacture tight Firmware not only has high efficiency and good quality, but also saves materials and costs. In actual production, due to the deformation and work hardening of metal materials during cold heading, a large amount of heat will be generated in the process of rapid plastic deformation, so it is necessary to cool down the mold in time; and the cooling effect of the existing mold is general, resulting in the mold The temperature is easily too high, which greatly affects the life of the cold heading die and reduce...
