Abstract
The utility model provides an oil quenching device, and belongs to the technical field of metal machining. According to the technical scheme, the oil quenching device comprises an oil quenching tank, a circulating oil pump, a heat sink and a water cooling tank, wherein the oil suction port of the circulating oil pump is connected to the oil quenching tank through an oil suction pipe, the oil drain port of the circulating oil pump is connected to the oil inlet of the heat sink through an oil drain pipe, the heat sink is fixed in the water cooling tank, and quenching oil discharged by the oil outlet of the heat sink flows to the oil quenching tank through an oil return pipe. The oil quenching device has the advantages that the quenching oil in the oil quenching tank is led into the external heat sink by using a circulating pipeline and is subjected to forced heat dissipation, so that when relatively large workpieces are continuously produced or treated, the quenching oil can be kept at a normal temperature, thus the quenching quality of the workpieces can be ensured, the quenching efficiency is improved, the floor area of the oil quenching device can also be greatly reduced, and the manufacturing cost of the oil quenching device is reduced.
Description
Technical field
The utility model relates to a kind of oily device of quenching for metal is heat-treated, and belongs to metalworking technology field.
Background technology
Oil quenching is steel part conventional heat treatment mode in production and process of the test, by oil quenching, can make steel part obtain high strength, high rigidity and high-wear resistance.Compare with the heat-eliminating medium such as salt solution, tap water, air, the speed of cooling of oil is lower than salt solution and tap water, again higher than the speed of cooling of air.Therefore, higher at some alloy contents, in the quenching technology of the good steel part of hardening capacity, oil quenching can make steel part obtain desirable martensitic stucture, can avoid again steel part too fast because of speed of cooling, and quenching stress deforms and even ftractures too greatly.
At present, oil quenching thermal treatment is all generally to carry out in fixing quenching tank, during quenching, workpiece is immersed in oil repeatedly, or workpiece is put into quenching tank and utilize stirring oil to carry out oil quenching.But when workpiece is produced more greatly or continuously, the oil temperature in quenching tank can rise rapidly, too high oil temperature will cause workpiece cannot obtain predetermined tissue, cause workpiece degradation even to be scrapped.
Too high for preventing the oil temperature in quenching tank, the general quenching tank that adopts large-size in industrial production, and in oil quenching treating processes, constantly in quenching tank, inject quenching oil, the quenching oil elevating the temperature overflows from quenching tank top, flows into storage tanks and concentrates cooling.This just need to prepare a large amount of quenching oils and take larger space, so cost is very high.
And conventionally only have a fixedly quenching tank while carrying out oil quenching thermal treatment in laboratory, and when oil temperature raises, stop experiment, after reducing, oil temperature proceeds again experiment, so just greatly reduce conventional efficient.
Utility model content
The purpose of this utility model is the drawback for prior art, and a kind of cheap for manufacturing cost and oily device of quenching that oil temperature is stable is provided.
Problem described in the utility model realizes with following technical proposals:
A kind of oily device of quenching, formation comprises the fuel tank of quenching, circulating oil pump, scatterer and water cooling box, the oil suction of described circulating oil pump connects through oil suction pipe the fuel tank of quenching, its oil discharge outlet connects the oil-in of scatterer through oil exit pipe, described scatterer is fixed in water cooling box, and the quenching oil that its oil outlet is discharged flows back to through used oil pipe the fuel tank of quenching.
The above-mentioned oily device of quenching, also comprises grooved separation net in formation, described grooved separation net is suspended in to be quenched in fuel tank and the flange by its notch is connected with the top side wall of the fuel tank of quenching.
The above-mentioned oily device of quenching, the oil inlet end of described oil suction pipe is between the sidewall of the fuel tank of quenching and the sidewall of grooved separation net and strainer is installed.
The above-mentioned oily device of quenching, a upper lateral part of described water cooling box is connected with water source by water-in, and the bottom of its opposite side is provided with water outlet.
The above-mentioned oily device of quenching, the oil inlet end of described oil suction pipe is connected with the bottom of fuel tank one side of quenching, and the oil outlet of described used oil pipe is connected with the top of the fuel tank opposite side of quenching.
The above-mentioned oily device of quenching, the bottom mesh of described grooved separation net and the mesh size of lower sidewall are less than the mesh size of its side wall upper part.
The utility model utilizes circulation line that the quenching oil in the fuel tank of quenching is caused and in external heat sink, carries out forced heat radiation, make quenching oil can keep normal temps when producing continuously or processing larger workpiece, so not only can guarantee the quenching quality of workpiece, improve quenching efficiency, but also can greatly reduce the floor space of quenching oily device, reduce the laid down cost of quenching oily device.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, each label is: the fuel tank of 1, quenching; 2, water cooling box; 3, grooved separation net; 4, oil suction pipe; 5, strainer; 6, circulating oil pump; 7, oil exit pipe; 8, water-in; 9, water outlet; 10, scatterer; 11, used oil pipe.
Embodiment
As shown in Figure 1, originally the oily device of quenching comprises quench fuel tank 1 and water cooling box 2, quench in fuel tank 1 grooved separation net 3 is housed, quench and be provided with the strainer 5 that is fixed on oil suction pipe 4 oil inlet ends between fuel tank 1 and the sidewall of grooved separation net 3, the oil outlet end of oil suction pipe 4 is connected with the oil suction of the circulating oil pump 6 of fuel tank 1 outside of quenching, the oil discharge outlet of circulating oil pump 6 is connected with the head end of oil exit pipe 7, the tail end of oil exit pipe 7 is connected with the oil-in of scatterer 10, scatterer 10 is located in water cooling box 2, its oil outlet joins through used oil pipe 11 and the top of the fuel tank of quenching, one upper lateral part of water cooling box 2 is provided with water-in 8, the opposite side bottom of water cooling box is provided with water outlet 9.
During oil quenching thermal treatment, start circulating oil pump 6, the quenching oil of quenching in fuel tank 1 enters scatterer 10 through strainer 5, oil suction pipe 4, circulating oil pump 6 and oil exit pipe 7 successively, in scatterer 10 with water cooling box 2 in flowing water carry out after heat exchange, through used oil pipe 11, enter and quench in fuel tank 1, realize circulation and the cooling of quenching oil.
When thermal treatment, the workpiece oil of quenching in grooved separation net 3, the surface of the oily part of quenching may have oxide skin to come off.Therefore because bottom and the bottom web hole dimension of grooved separation net 3 sidewalls are less, can guarantee that most oxide skin stays in grooved separation net 3.Although a small amount of oxide skin can drop in the impact of quenching oil the outside of grooved separation net 3, the restriction that is subject to strainer 5 can not enter in oil suction pipe 4, thereby can guarantee that circulation line does not stop up.
