Description

Technical Field

[0001] This utility model relates to the field of metal parts processing, and more specifically, to a rapid cooling device for quenching metal parts. Background Technology

[0002] In the field of metal processing, quenching is a key process to improve the mechanical properties of metal parts, such as hardness and strength, while the cooling process directly affects the quenching quality.

[0003] Traditional metal quenching and cooling devices mostly use a single coolant spraying or immersion method, which has problems such as low cooling efficiency and inability to recycle coolant. This not only leads to unstable quenching effect of metal parts, but also causes a lot of coolant waste, increasing production costs. At the same time, impurities such as metal shavings and oxide scale generated during the cooling process can easily mix into the coolant, clogging pipes and affecting the cooling effect. Furthermore, existing devices are inconvenient to clean and maintain, requiring frequent shutdowns to disassemble parts, which reduces production efficiency.

[0004] Therefore, it is necessary to redesign a rapid cooling device for quenching metal parts to address the above-mentioned problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a rapid cooling device for quenching metal parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid cooling device for quenching metal parts includes a cooling box. Two mounting blocks are symmetrically fixedly installed on both sides of the cooling box. A water storage tank is fixedly connected between the two mounting blocks on the same side. A connecting pipe is fixedly connected between the water storage tank and the cooling box. A cooling device is provided on one side of each water storage tank. A refrigeration device is provided on each water storage tank. Sliding grooves are opened on the inner walls of both sides of the cooling box. A slider is slidably connected in each sliding groove. A filter plate is fixedly connected between two sliders. Two collection grooves are symmetrically opened on the upper end face of the filter plate. Two moving grooves are symmetrically opened on the upper end face of the filter plate. A mounting plate is slidably connected in each moving groove. A fixing plate is fixedly installed on the upper end face of the two mounting plates. A scraping device is provided on the fixing plate, and the output end of the scraping device is in contact with the surface of the filter plate.

[0008] In a preferred embodiment, each of the cooling devices includes a circulation pump, which is fixedly installed on one side of the water storage tank and communicates with the interior of the water storage tank. A spiral pipe is fixedly connected to the circulation pump, and a connecting pipe is fixedly connected to the end of the spiral pipe away from the circulation pump. One end of the connecting pipe is fixedly connected to a nozzle.

[0009] In a preferred embodiment, each scraping device includes two springs, which are symmetrically fixedly installed on the upper surface of the fixed plate. A connecting block is fixedly installed at one end of each spring, and a connecting rod is fixedly installed at the bottom end of each connecting block. The bottom ends of the two connecting rods slide through the upper surface of the fixed plate and are jointly installed downwards on the connecting plate. A cleaning brush is fixedly installed at the bottom end of the connecting plate, and the cleaning brush is in contact with the surface of the filter plate.

[0010] In a preferred embodiment, each of the moving slots has through slots on both sides of its inner wall, and the two through slots are respectively connected to two collecting slots.

[0012] In a preferred embodiment, a fixing block is fixedly installed on the upper surface of each water storage tank, and one end of the fixing block is fixedly connected to the outer wall of the connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a cooling device, a water storage tank and other devices, and forming a coolant circulation system through components such as refrigeration equipment, a circulating pump and spiral pipes, allows the coolant to be continuously cooled in the refrigeration equipment, and then transported to the cooling tank by the circulating pump to cool the metal parts.

This cycle is repeated, which not only ensures continuous and efficient cooling of the metal parts, but also greatly improves the utilization rate of coolant, reduces coolant consumption, lowers operating costs and achieves the goal of energy saving.

[0015] 2.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-5 A rapid cooling device for quenching metal parts includes a cooling box 1. Two mounting blocks 23 are symmetrically fixedly installed on both sides of the cooling box 1. A water storage tank 2 is fixedly connected between the two mounting blocks 23 on the same side. A connecting pipe 22 is fixedly connected between the water storage tank 2 and the cooling box 1. It should be noted that the connecting pipe 22 is a one-way pipe, which only allows the liquid in the cooling box 1 to flow into the water storage tank 2.

[0025] Each water storage tank 2 is equipped with a cooling device on one side and a refrigeration device 3 on each water storage tank 2. The inner walls of both sides of the cooling tank 1 are respectively provided with sliding grooves 9. Each sliding groove 9 is slidably connected with a slider 11. A filter plate 10 is fixedly connected between the two sliders 11. Two collection grooves 14 are symmetrically opened on the upper end face of the filter plate 10. Two moving grooves 12 are symmetrically opened on the upper end face of the filter plate 10. An installation plate 15 is slidably connected in each moving groove 12. A fixing plate 16 is fixedly installed on the upper end face of the two installation plates 15. A scraping device is provided on the fixing plate 16, and the output end of the scraping device is in contact with the surface of the filter plate 10.

[0026] Each cooling device includes a circulation pump 4, which is fixedly installed on one side of the water storage tank 2 and is connected to the interior of the water storage tank 2. A spiral pipe 5 is fixedly connected to the circulation pump 4, and a connecting pipe 6 is fixedly connected to the end of the spiral pipe 5 away from the circulation pump 4. One end of the connecting pipe 6 is fixedly connected to a nozzle 7. The spiral pipe 5 extends the flow path of the coolant from the circulation pump 4 to the nozzle 7, which allows the coolant to stay in the pipe for a longer time and has more time for heat exchange. This allows the coolant to fully absorb the heat around the spiral pipe 5, thereby more efficiently cooling the coolant before it is sprayed out of the nozzle 7, which helps to improve the cooling effect on metal parts.

[0027] Each scraping device includes two springs 17, which are symmetrically fixedly installed on the upper surface of the fixed plate 16. A connecting block 18 is fixedly installed at one end of each spring 17, and a connecting rod 19 is fixedly installed at the bottom end of each connecting block 18. The bottom ends of the two connecting rods 19 slide through the upper surface of the fixed plate 16 and are installed together downwards on a connecting plate 20. A cleaning brush 21 is fixedly installed at the bottom end of the connecting plate 20, and the cleaning brush 21 is in contact with the surface of the filter plate 10. The springs 17 and the cleaning brush 21 can maintain contact with the surface of the filter plate 10.

[0028] Each moving trough 12 has through grooves 13 on both inner walls, and the two through grooves 13 are respectively connected to the two collection troughs 14. Thus, when impurities enter the moving trough 12, they can be pushed into the collection trough 14 through the through grooves 13 by the movement of the mounting plate 15.

[0029] Each water storage tank 2 has a fixed feed pipe connected to its upper end, through which appropriate liquids or substances can be added to the water storage tank 2 to ensure the performance and cooling effect of the coolant.

[0030] Each water storage tank 2 has a fixing block 8 fixedly installed on its upper surface, and one end of the fixing block 8 is fixedly connected to the outer wall of the connecting pipe 6.

[0031] In use, during the quenching and cooling process of the metal parts, the refrigeration equipment 3 cools the coolant in the water storage tank 2, keeping it at a low temperature. The circulation pump 4 starts, drawing out the low-temperature coolant from the water storage tank 2, delivering it through the spiral pipe 5 to the connecting pipe 6, and then spraying it into the cooling box 1 through the nozzle 7 to rapidly cool the quenched metal parts. After heat exchange between the coolant and the metal parts in the cooling box 1, the temperature rises, and it flows back to the water storage tank 2 through the connecting pipe 22, where it is cooled again by the refrigeration equipment 3. This cycle repeats continuously, achieving the recycling of the coolant and a continuous cooling effect.

[0032] The filter plate 10 is slidably installed in the slide groove 9 within the cooling box 1 via the slider 11, which can filter impurities generated during the cooling process. When the coolant flows in the cooling box 1, the impurities are intercepted by the filter plate 10, and the filtered coolant remains at the bottom of the cooling box 1 and then flows back to the water storage tank 2 through the connecting pipe 22.

[0033] When the filter plate 10 needs to be cleaned, the mounting plate 15 is pushed to slide in the moving groove 12, which drives the fixed plate 16 and the cleaning device to move. The spring 17 on the fixed plate 16 is in a compressed state, which generates a downward elastic force on the connecting block 18, so that the connecting rod 19 drives the connecting plate 20 and the cleaning brush 21 to stick to the surface of the filter plate 10. As the fixed plate 16 moves, the cleaning brush 21 brushes the surface of the filter plate 10 to further remove impurities. The impurities that are brushed off also enter the collection groove 14 through the through groove 13, thereby achieving the cleaning of the filter plate 10.

[0034] When it is necessary to replenish coolant or add other additives, the corresponding liquid or substance can be added to the water tank 2 through the feed pipe on the upper end of the water tank 2 to ensure the performance and cooling effect of the coolant.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
