[0002] Although springs are only a small component in mechanical equipment, their role is absolutely invaluable. There are two methods for manufacturing springs: cold coiling and hot coiling. Generally, springs with a wire diameter of less than 8 mm are cold coiled, while those with a diameter greater than 8 mm are hot coiled. After hot coiling, springs need to undergo quenching treatment. The quenching and cooling of springs is a process of rapidly cooling the heated springs in cold oil to obtain better performance from the springs.

[0003] In the prior art, Chinese utility model patent with patent number CN219260094U discloses a quenching mechanism for hot coil spring processing, including a lifting pallet and a quenching box for holding quenching oil. The lifting pallet is movably installed inside the quenching box. The upper outer surface of the lifting pallet has an inclined structure. The surface of the lifting pallet is provided with several sets of filter tanks for separating the quenching oil and the hot coil spring. The several sets of filter tanks are arranged side by side. A first hydraulic rod and a second hydraulic rod are movably installed on the lower part of both sides of the lifting pallet, and the first hydraulic rod and the second hydraulic rod are arranged side by side.

[0004] In the aforementioned prior art, although the quenching oil in the coil is cooled by a fan to maintain its temperature at room temperature, thus improving the cooling and quenching effect of the hot-rolled spring and preventing high temperatures in the quenching oil, thereby enhancing the quenching effect of the quenching mechanism used for hot-rolled spring processing, a problem arises: when the hot-rolled spring is removed after quenching, cooling oil residue remains on the spring surface, forming an uneven film that affects the spring's appearance and subsequent processing, while also wasting cooling oil. Utility Model Content

[0005] This invention addresses the technical problem of residual cooling oil on the spring surface forming an uneven film that affects the spring's appearance and subsequent processing, while also wasting cooling oil. It provides a hot-rolled spring quenching device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot-rolled spring quenching device, comprising a base, a quenching box fixedly mounted on the upper surface of the base, a first filter frame disposed inside the quenching box, and a protrusion fixedly connected to the bottom of the first filter frame.

[0007] The inner wall of the quenching box is fixedly installed with multiple elastic plates, and one end of each elastic plate is fixedly installed with a striking head that cooperates with a protrusion.

[0008] Multiple first fans are fixedly installed on the outside of the quenching box.

[0009] Optionally, a column is fixedly installed on the upper surface of the base, a lead screw is rotatably installed inside the column, and a servo motor for driving the lead screw is fixedly installed on the top of the column. A sliding groove is provided on one side of the column, and a slider that slides inside the sliding groove is threaded onto the surface of the lead screw.

[0010] Optionally, a U-shaped fixing frame is fixedly installed on the upper surface of the slider, and one end of the fixing frame is fixed to the first filter frame.

[0011] Optionally, a filter box is fixedly installed on the upper surface of the base, a second fan is fixedly installed on the top of the filter box, a duct is connected to the top of the second fan, and a fan hood is connected to the other end of the duct.

[0012] Optionally, a detachable second filter frame is installed in the inner cavity of the filter box, and an atomizing nozzle is fixedly installed on one side of the filter box.

[0013] Optionally, the bottom of the second filter frame is connected to an oil-water inlet pipe, the bottom of the oil-water inlet pipe is connected to an oil-water separator filter element, one side of the filter box is connected to an oil drain pipe, and the bottom of the oil-water separator filter element is connected to a drain pipe.

[0014] In summary, compared with the prior art, the hot-rolled spring quenching device provided by this utility model has the following beneficial effects:

[0015] 1. In this utility model, the first filter frame is vibrated by the tapping head continuously tapping the protrusion, which shakes off the cooling oil that adheres to the spring after quenching. At this time, the first fan is started to blow air forcefully on the spring of the first filter frame, further blowing off the cooling oil that adheres to the spring. This not only saves the use of cooling oil, but also facilitates the subsequent processing of the cooling oil on the surface of the spring.

[0016] 2. In this utility model, the rotation of the servo motor drives the connected lead screw to rotate, thereby causing the slider to slide up and down inside the slide groove, which in turn drives the first filter frame to move up and down through the fixed frame, facilitating the feeding and unloading of materials by the spring and speeding up the work efficiency;

[0017] 3. In this utility model, the quenched oil fumes are collected and filtered by a second fan, and the oil-water mixture after water spraying is filtered and separated by an oil-water separator filter element, and the cooling oil is recycled to reduce the cost of use.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] refer to Figure 1 A hot-rolled spring quenching device includes a base 1, a support leg 2 fixedly installed on the lower surface of the base 1, and a quenching box 3 fixedly installed on the upper surface of the base 1.

[0026] refer to Figure 1 and Figure 5 A column 4 is fixedly installed on the upper surface of the base 1 and on one side of the quenching box 3. A lead screw 5 is rotatably installed inside the column 4, and a servo motor 6 for driving the lead screw 5 is fixedly installed on the top of the column 4. A slide groove 8 is opened on one side of the column 4, and a slider 7 that slides inside the slide groove 8 is threaded on the surface of the lead screw 5.

[0027] Furthermore, the rotation of the servo motor 6 drives the lead screw 5 connected to it to rotate, thereby causing the slider 7 to slide up and down inside the slide groove 8.

[0028] refer to Figures 1-3A U-shaped fixing frame 9 is fixedly installed on the upper surface of the slider 7. A first filter frame 10 is fixedly installed at one end of the fixing frame 9. The first filter frame 10 is placed inside the quenching box 3 to place the spring into the quenching box 3 for quenching. A protrusion 11 is fixedly connected to the bottom of the first filter frame 10. Multiple elastic plates 12 are fixedly installed on the inner wall of the quenching box 3. A striking head 13 that cooperates with the protrusion 11 is fixedly installed at one end of the elastic plate 12. Multiple first fans 14 are fixedly installed on the outer side of the quenching box 3.

[0029] Furthermore, during use, the fixing frame 9 drives the first filter frame 10 to move up and down, facilitating the quenching and removal of the spring. The fixing frame 9 drives the first filter frame 10 to descend and quench the spring. At this time, the protrusion 11 is located below the striking head 13. After quenching, the fixing frame 9 drives the first filter frame 10 to move up, and the protrusion 11 drives the striking head 13 to move up. After the protrusion 11 moves up, the elastic plate 12 shakes, which in turn drives the striking head 13 to strike the protrusion 11. This causes the striking head 13 to continuously strike the protrusion 11, thereby vibrating the first filter frame 10 and shaking off the cooling oil that adheres to the spring after quenching. At this time, the first fan 14 starts to blow a strong airflow onto the spring of the first filter frame 10, further blowing off the cooling oil that adheres to the spring. This saves on the use of cooling oil and facilitates the subsequent processing of the cooling oil on the spring surface. The contact position between the striking head 13 and the protrusion 11 is rounded to facilitate sliding between the two.

[0030] refer to Figure 1 A filter box 15 is fixedly installed on the upper surface of the base 1 and on the other side of the quenching box 3. A second fan 16 is fixedly installed on the top of the filter box 15. A duct 17 is connected to the top of the second fan 16. The other end of the duct 17 is connected to a fan hood 18 fixedly installed on one side of the top of the filter box 15. The fan hood 18 is used in conjunction with the quenching box 3 to draw the oil fumes generated during spring quenching into the filter box 15.

[0031] refer to Figure 4 The filter box 15 is equipped with a detachable second filter frame 20 in its inner cavity for filtering impurities in the oil fumes. Atomizing nozzle 19 is fixedly installed on one side of the filter box 15 for dust suppression and cooling of the inhaled oil fumes. One end of the atomizing nozzle 19 is connected to an external water supply device.

[0032] refer to Figure 4The bottom of the second filter frame 20 is connected to an oil-water inlet pipe 21, and the bottom of the oil-water inlet pipe 21 is connected to an oil-water separator filter element 22. The oil-water separator filter element 22 is existing technology. Oil and water have different densities, and the oil-water separator filter element 22 utilizes this characteristic to allow oil and water to separate naturally as they pass through it. The oil-water separator filter element 22 is typically composed of multiple layers of filter media with different pore sizes. Water molecules are blocked by the small pores on the oil-water separator filter element 22, while oil molecules can pass through, thus achieving oil-water separation. One side of the filter box 15 is connected to an oil drain pipe 24 for discharging the cooling oil filtered by the oil-water separator filter element 22 for recycling. The bottom of the inner cavity of the filter box 15 is inclined for collecting cooling oil. The bottom of the oil-water separator filter element 22 is connected to a drain pipe 23, which runs through the filter box 15 and the base 1 to discharge the filtered water.
