A cooling oil spraying device for cold heading processing of nuts

Abstract

The invention discloses a cooling oil spraying device for nut cold heading processing, which comprises a nut cold heading machine body, an oil replenishing mechanism is arranged on the lower end side of the nut cold heading machine body, and an oil supply mechanism is arranged inside the nut cold heading machine body. There is a cooling oil circulation spraying mechanism, a blockage detection mechanism is provided on one side of the cooling oil circulation spraying mechanism, and a blockage dredging mechanism is provided on the side of the cooling oil circulation spraying mechanism. The beneficial effect of the present invention is that the device prolongs the flow time of the cooling oil, facilitates its cooling, intercepts most of the impurities through the partition, and can also flush out the blocked impurities in the conduit, without maintenance by staff, and is convenient for spraying Cooling oil improves work efficiency.

Description

Technical field [0001] The present invention relates to the technical field of nut cold heading machine equipment, more particularly, to a cooling oil spraying device for nut cold heading processing. Background [0002] Nut cold heading machine is based on the theory of metal plastic change, at room temperature to apply a certain pressure to the metal blank, so that it produces plastic change in the mold cavity, according to the specified shape and size molding, in the cold heading of the metal blank, will produce a certain amount of heat, the need to spray cooling oil on the mold and blank to cool down. [0003] In the prior art, the nut cold heading machine has a plurality of stations, when spraying cooling oil is generally pumped through the oil pump to the spraying box, a plurality of injection pipes are connected on the spraying box and the cooling oil is sprayed out, so that multiple stations can be cooled, but there are some problems in its use, the cooling oil is cooled o...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are multiple stations on the nut cold heading machine. When spraying the cooling oil, the cooling oil is usually pumped into the spray box by the oil pump, and a plurality of oil spray pipes are connected to the spray box to spray the cooling oil, thereby It can cool multiple stations, but there are some problems in its use. After the cooling oil cools the mold and the billet, its own temperature will increase, which will affect the cooling effect. When spraying the cooling oil, it needs to pass through the conduit to The oil is transported to the top, and the conduit generally adopts a rubber tube, which can be bent arbitrarily, so that the various devices on the nut cold heading machine body can be avoided, but there will be some impurities in the cooling oil during use, and these impurities will enter the oil pipe , and it is easy to accumulate at the position where the conduit is bent, thereby clogging, making it impossible to spray the cooling oil, thus affecting the quality of the workpiece, it is necessary to close the nut cold heading machine, and the conduit can be used after the staff dredges and repairs it. work efficiency
