Description

Technical Field

[0001] The utility model relates to the technical field of steel wire processing, in particular to a quenching device for steel wire processing. Background Art

[0002] With the development of industrial technology, high-strength steel wire is widely used in many fields such as automobile, aerospace, and machinery manufacturing. The quenching process can improve the strength and wear resistance of steel wire and is currently a commonly used process in the field of steel wire processing. The cooling medium used for quenching of steel wire is generally water. The temperature of water will rise after contacting with the heated and insulated steel wire.

[0018] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0019] like Figures 1 to 4 As shown, the embodiment of the utility model provides a quenching device for steel wire processing, including a base plate 1, a quenching pool 2 and a cooling box 3 are arranged on the base plate 1, a wheel frame 4 is arranged on the quenching pool 2, and a plurality of rollers 5 are arranged on the wheel frame 4, each roller 5 includes two rollers arranged in parallel, each roller can rotate freely on the wheel frame 4, and the wheel grooves of the two rollers 5 are relatively matched to form a wire hole 6 for the steel wire to pass through. An outlet pipe 7 and a return pipe 8 are arranged on the quenching pool 2, and the outlet pipe 7 and the return pipe 8 are both connected to the cooling box 3. The outlet pipe cooling box 3 can cool the water flowing out of the outlet pipe 7, and then send it back to the quenching pool 2 from the return pipe 8. In order to facilitate maintenance, a valve 9 can be set on the outlet pipe 7 and the return pipe 8.

[0020] The cooling box 3 of the embodiment of the utility model comprises a box body 31, on which an air inlet flange 32 and an air outlet flange 33 are arranged. In order to filter the cooling air entering the box body 31, an air filter 34 is preferably arranged inside the air inlet flange 32, and the air filter 34 is preferably a flame-retardant fiber filter cotton. A condenser 35 and a fan 36 are arranged between the air inlet flange 32 and the air outlet flange 33. The condenser 35 is respectively connected to the refrigerant outlet of the compressor 37 and one end of the expansion valve 38. The other end of the expansion valve 38 is connected to the evaporative heat exchanger 39. The evaporative heat exchanger 39 is connected to the water outlet pipe 7 through the water pump 310. The evaporative heat exchanger 39 is also respectively connected to the return pipe 8 and the air inlet of the compressor 37. The high-temperature refrigerant discharged by the compressor 37 flows into the condenser 35 for heat dissipation, and becomes a low-temperature liquid refrigerant after passing through the expansion valve 38, and flows into the evaporative heat exchanger 39 for evaporation, absorbs the heat in the water extracted from the water outlet pipe 7 by the water pump 310, and then flows back to the air inlet of the compressor 37. The low-temperature water discharged from the evaporative heat exchanger 39 flows back to the quenching pool 2 from the return pipe 8, thereby ensuring that the water temperature in the quenching pool 2 is not too high and meets the quenching process requirements. The hot air discharged from the air outlet flange 33 can be led to a designated area such as the outdoors through the air duct.

[0021] In order to prevent impurities from entering from the outlet pipe 7 and the return pipe 8 , a filter screen 10 is preferably provided at the bottom of the quenching tank 2 on the upper side of the outlet pipe 7 and the return pipe 8 .

[0022] The wheel frame 4 of the embodiment of the utility model includes a bottom plate 41 fixed on the quenching tank 2, and the bottom plate 41 can be fixed on the quenching tank 2 by welding. Two mounting plates 42 are fixed at intervals on the upper side of the bottom plate 41, and the roller 5 is arranged between the two mounting plates 42. In order to improve stability, it is also preferred to fix a plurality of support blocks 43 between the upper ends of the two mounting plates 42. In order to increase the flowability of water between the two mounting plates 42 and the water outside the mounting plates 42, it is also preferred to set a plurality of through holes 44 on the mounting plates 42, and the through holes 44 are preferably long strips.

[0023] To facilitate installation, it is preferred to set a bracket 11 on the upper side of the seat plate 1, place the quenching pool 2 on the upper side of the bracket 11, set the lower end of the quenching pool 2 at a distance from the seat plate 1, and set the cooling box 3 on the seat plate 1 on the lower side of the quenching pool 2.

[0024] During use, the water in the quenching pool 2 will gradually evaporate and be polluted, so it is necessary to regularly replenish water in the quenching pool 2 through an external water replenishing mechanism, and replace the entire quenching pool 2 when the pollution is serious. In order to facilitate the discharge of water in the quenching pool 2, a drain pipe 12 is preferably provided at the bottom of the quenching pool 2, and a drain valve 13 is provided on the drain pipe 12. The water in the quenching pool 2 can be discharged by opening the drain valve.

[0025] When in use, the device is arranged at the rear side of the wire heating and heat preservation device. A pulling mechanism or a wire-reeling mechanism may be arranged at the rear side of the device to provide power for the steel wire to move, so that the heated steel wire can pass through the wire hole 6 and be quenched in the quenching pool 2.

[0026] The above is only a preferred embodiment of the utility model. It should be pointed out that for ordinary technicians in this technical field, other parts not specifically described belong to the prior art or common knowledge.
