[0030] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Now, the preferred embodiments of the present application will be described in detail with reference to the drawings.

[0031] Reference Figure 1 and Figure 2As shown, it displays an embodiment of the cooling device 1 and the wire drawing machine. The cooling device 1 comprises a box body 11 and a filter 12, the inside of the box body 11 forms a cooling cavity 111, the outer surface of the box body 11 is provided with a backflow port 112 and a water supply port 113 which penetrate into the cooling cavity 111; the filter 12 is fixedly arranged in the cooling cavity 111; wherein the cold water enters the cooling cavity 111 through the backflow port 112 to cool the drawing oil, and is discharged from the water supply port 113 through the filter 12, the drawing oil enters the cooling cavity 111 through the water supply port 113 and is cooled by the cold water, and is discharged from the backflow port 112 through the filter 12.

[0032] Specifically, in the production process of the wire drawing machine, the wire drawing machine will generate a large amount of heat, and most of the existing wire drawing machines cool and lubricate the metal wire, mold and working area by circulating the drawing oil. During the circulation of the drawing oil, the temperature of the drawing oil gradually rises. When the temperature of the drawing oil is too high, it will cause the wire drawing material to overheat. The high temperature of the drawing oil may cause the wire drawing material to overheat, exceeding its melting point or thermal stability range. This may cause decomposition, degradation or burning of the material, thereby affecting the wire drawing quality and product performance; at the same time, it will cause the degradation of the drawing oil: high temperature may cause the decomposition and degradation of the drawing oil, which may lose its original performance and stability, which may cause the viscosity of the drawing oil to increase, oxidize, deteriorate or produce harmful substances, thereby affecting the wire drawing quality and product performance; it will also cause the volatilization of the drawing oil: high temperature may cause the volatile components in the drawing oil to volatilize, thereby causing the imbalance of the components of the drawing oil, which may affect the lubricating performance and lubricating effect of the drawing oil, causing difficulty in wire drawing, poor surface quality or other problems; finally, it will also cause the increase of energy consumption: high temperature needs more energy to heat the drawing oil, thereby increasing the energy consumption and production cost. Therefore, in the operation of the wire drawing machine, the drawing oil also needs to be cooled to reduce the temperature of the drawing oil, solve the problems of material softening, mold wear and bare wire oxidation of the wire drawing machine, and improve the product quality.

[0033] The application provides a cooling device 1, which comprises a box 11 and a filter 12, the box 11 is used for storing cold water and drawing oil, the cold water exchanges heat with the drawing oil in the box 11 by using the high heat conductivity and high specific volume of the cold water, the cold water takes away the heat of the drawing oil, so that the drawing oil is cooled; the box 11 is internally formed with a cooling cavity 111, the cooling cavity 111 is a sealed structure, so that the cold water and the drawing oil can be stored in the cooling cavity 111; the box 11 is also provided with a backflow port 112 and a water supply port 113, the backflow port 112 and the water supply port 113 are both formed by extending the outer surface of the box 11 towards the cooling cavity 111, and the backflow port 112 and the water supply port 113 both penetrate into the cooling cavity 111, the backflow port 112 and the water supply port 113 are arranged at the top end of the box 11, the backflow port 112 is used for the outside to introduce the cold water into the cooling cavity 111, and the backflow port 112 is also used for the drawing oil cooled in the cooling cavity 111 to flow to the outside through the backflow port 112; the water supply port 113 is used for the outside to introduce the high-temperature drawing oil into the cooling cavity 111, and the water supply port 113 is also used for the cold water after heat exchange to flow to the outside through the water supply port 113, so that the cold water and the drawing oil after heat exchange can be circulated in the outside; that is, the drawing oil flows into the cooling cavity 111 through the water supply port 113, the cold water flows into the cooling cavity 111 through the backflow port 112, the cold water and the drawing oil exchange heat in the cooling cavity 111, so as to cool the drawing oil, the drawing oil after cooling flows to a production device 2 through the backflow port 112 to cool and lubricate the wire, the mold and the equipment; and the cold water after cooling the drawing oil flows to the production device 2 through the water supply port 113 to further cool and dissipate heat of the production device 2, improve the production efficiency and service life of the equipment.

[0034] Meanwhile, the filter 12 is fixedly arranged in the cooling cavity 111, the filter 12 is used for distinguishing the cold water and the drawing oil, so that the cold water and the drawing oil after heat exchange can flow out of the cooling cavity 111 through the water supply port 113 and the backflow port 112 respectively, so as to be circulated in the outside; meanwhile, the filter 12 can also be used for filtering the impurities in the cold water and the drawing oil, so that the cold water and the drawing oil flowing out of the cooling cavity 111 have high cleanliness, avoid the impurities from entering the production device 2 to cause blockage or pollution, and meanwhile avoid affecting the quality of the drawing oil, finally affecting the effect of the drawing oil.

[0035] When the cooling device 1 is started, high-temperature drawing oil flows into the cooling cavity 111 through the water inlet 113, and low-temperature cold water flows into the cooling cavity 111 through the backflow port 112. The cold water in the cooling cavity 111 is discharged to the outside through the filter 12 from the water inlet 113, and the drawing oil in the cooling cavity 111 is discharged to the outside through the filter 12 from the backflow port 112, so as to realize the cooling process of the cold water on the drawing oil.

[0036] The cooling device 1 is arranged in the box 11, and the cooling cavity 111 is formed in the box 11 as a heat exchange place for the cold water and the drawing oil. The high-temperature drawing oil is introduced into the cooling cavity 111 through the water inlet 113, and the cold water is introduced into the cooling cavity 111 through the backflow port 112, so as to realize the heat absorption and cooling of the cold water on the drawing oil. The cold water in the cooling cavity 111 flows out through the filter 12 from the water inlet 113, and the drawing oil flows out through the filter 12 from the backflow port 112, so as to realize the cooling of the drawing oil in the box 11. The cooled drawing oil can be reused, so as to reduce the production cost. The low-temperature drawing oil can realize multiple functions in the production process of the drawing machine. First, the friction heat is reduced. In the drawing process, a large amount of heat is generated between the metal wire and the die due to friction, which causes oxidation of the bare wire. The drawing oil can quickly take away the friction heat through its cooling performance, so as to keep the temperature of the wire and the die within a controllable range, thereby avoiding material softening, die wear and oxidation of the bare wire caused by high temperature. Second, the processing efficiency is improved. The drawing oil with good cooling effect can effectively reduce the temperature fluctuation in the processing, so as to make the drawing process more stable and efficient. The low temperature not only helps to improve the smoothness of the wire surface, but also can prolong the service life of the die. Finally, the material deformation is prevented. High temperature is easy to cause thermal expansion and deformation of the metal material, which affects the size accuracy of the finished product. Through continuous cooling, the drawing oil can help to keep the size stability of the material, so as to ensure that the product meets the requirements of precision machining.

[0037] Therefore, the cooling device cools the drawing oil, so as to avoid the problems of material softening, die wear and oxidation of the bare wire of the drawing machine, and finally affects the product quality of the drawing machine production.

[0038] In specific embodiments, reference is made to Figure 1 and Figure 2As shown, the filter element 12 is a filter screen, with its upper and lower ends fixedly connected to the upper and lower ends of the housing 11, respectively. The water supply port 113 and the return port 112 are located on both sides of the filter screen. Specifically, the filter element 12 is used to separate cold water and drawing oil, so that the cold water and drawing oil after heat exchange can flow out of the cooling chamber 111 through the water supply port 113 and the return port 112, respectively, and circulate externally. At the same time, the filter element 12 can also be used to filter impurities in the cold water and drawing oil, so that the cold water and drawing oil flowing out of the cooling chamber 111 have high cleanliness, preventing impurities from entering the production device 2 and causing blockage or pollution, while also avoiding affecting the quality of the drawing oil and ultimately its function.

[0039] The filter element 12 is configured as a filter screen, which is fixed inside the cooling chamber 111. The upper and lower ends of the filter screen are fixedly connected to the upper and lower ends of the housing 11, respectively. The filter screen extends along the width direction of the cooling chamber 111, and both ends of the filter screen extend to abut against the two ends of the housing 11, thereby dividing the cooling chamber 111 into two regions. The two regions are located on both sides of the filter screen and are interconnected through the filter screen. The water supply port 113 and the return port 112 are located on both sides of the filter screen, that is, the water supply port 113 and the return port 112 are connected to the two regions, respectively.

[0040] When cold water enters one area of ​​the cooling chamber 111 through the return port 112, it flows through the filter screen towards another area of ​​the cooling chamber 111 and towards the water supply port 113, eventually flowing out through the water supply port 113; when wire drawing oil enters one area of ​​the cooling chamber 111 through the water supply port 113, it flows through the filter screen towards another area of ​​the cooling chamber 111 and towards the return port 112, eventually flowing out through the return port 112.

[0041] Therefore, both cold water and drawing oil need to pass through the filter screen during their flow to remove impurities from the cold water and drawing oil. This ensures high cleanliness of the cold water and drawing oil flowing to the outside, preventing impurities from entering the production unit 2 and causing blockages or contamination. It also prevents the quality of the drawing oil from being affected, which would ultimately impact its function. At the same time, the filter screen separates the cold water and drawing oil into two areas, allowing them to flow out from the water supply port 113 and the return port 112, respectively.

[0042] More specifically, the filter screen is arranged in a direction perpendicular to the upper and lower end faces of the housing 11, and the filter screen is located on the plane where the center line of the housing 11 is located, thereby dividing the cooling cavity 111 into two regions with equal volume to improve the structural stability of the housing 11.

[0043] In an embodiment, the cooling device 1 further comprises a first pipe and a first driving member (not shown in the figure), the first driving member is fixedly connected with the backflow port 112, and one end of the first pipe is connected with the first driving member; wherein when the first driving member is started, cold water enters the cooling cavity 111 along the first pipe. Specifically, the cooling device 1 further comprises a first pipe and a first driving member, the first pipe is used for introducing cold water to the cooling cavity 111, and the first driving member is used as a power source of liquid flow to drive the flow of cold water or drawing oil; the first driving member is fixedly connected with the backflow port 112, and one end of the first driving member is further connected with one end of the first pipe, so that the first pipe, the first driving member and the cooling cavity 111 form a flow channel of cold water, and the other end of the first pipe can be connected with the production device 2 of the drawing machine or other pipes, structural members and the like, so that cold water can flow to the cooling cavity 111 along the first pipe.

[0044] Wherein when the first driving member is started, cold water can flow into the cooling cavity 111 along the first pipe. Therefore, the cooling device 1 has a simple way of introducing cold water, simple structure, easy assembly and high structural stability.

[0045] In a specific embodiment, the cooling device 1 further comprises a second pipe (not shown in the figure), one end of the second pipe is connected with the first driving member; wherein when the first driving member is started, the drawing oil in the cooling cavity 111 flows to the second pipe through the backflow port 112 and flows to the production device 2 of the drawing machine. Specifically, the cooling device 1 further comprises a second pipe, the second pipe is used for discharging drawing oil, the second pipe is located on the same side as the first pipe, and one end of the second pipe and one end of the first pipe are both connected with the first driving member, so that the first driving member is used to realize the extraction of cold water in the cooling cavity 111 along the first pipe and the discharge of drawing oil along the second pipe; the other end of the second pipe is connected with the production device 2 of the drawing machine, so that the drawing oil can flow to the production device 2 of the drawing machine along the second pipe, so as to recycle the drawing oil after cooling to lubricate and cool the production device 2, avoid the problems of material softening, mold wear and bare wire oxidation of the drawing machine, and improve the product quality.

[0046] When the first driving member is started, the drawing oil in the cooling cavity 111 is extracted by the first driving member, the drawing oil flows to the direction of the second pipe through the backflow port 112, and circulates in the drawing machine to cool the drawing machine and lubricate the wire and the mold.

[0047] The cooling device 1 has high flow control for cold water and drawing oil, high structural stability, cold water flows into the cooling cavity through the first pipeline, drawing oil flows from the cooling cavity 111 to the production device 2 of the drawing machine through the second pipeline, so that the flow channels of cold water and drawing oil are different, to ensure the smooth flow of cold water and drawing oil, ensure the quality of drawing oil and cold water, and improve the cooling efficiency of the production device 2; meanwhile, one second driving member 13 is used as a power source to reduce production cost.

[0048] In an embodiment, the return port 112 is further provided with a first valve (not shown in the figure) for controlling the flow direction of cold water and drawing oil. Specifically, the return port 112 is further provided with a first valve for controlling the flow direction of cold water and drawing oil, that is, the first valve controls whether cold water flows from the first pipeline to the return port 112 and then into the cooling cavity 111, and whether drawing oil flows from the cooling cavity 111 to the return port 112 and then into the second pipeline, by closing or connecting the first pipeline and the return port 112, and by closing or connecting the second pipeline and the return port 112.

[0049] When the first valve opens the connection between the first pipeline and the return port 112 and closes the connection between the second pipeline and the return port 112, cold water flows along the first pipeline to the return port 112 and finally into the cooling cavity 111 under the drive of the first driving member; when the first valve opens the connection between the second pipeline and the return port 112 and closes the connection between the first pipeline and the return port 112, drawing oil flows from the return port 112 to the second pipeline and then to the production device 2 of the drawing machine under the drive of the first driving member to lubricate and cool the production device 2.

[0050] Therefore, in this embodiment, the first valve is fixed to the return port 112 to control the flow direction of cold water and drawing oil, thereby reducing production cost, ensuring the reliable flow direction of cold water and drawing oil, and improving the structural stability of the cooling device 1.

[0051] In one embodiment, the cooling device 1 further includes a cooling fan assembly (not shown in the figure), the two ends of which are connected to the production device 2 of the wire drawing machine and the first pipe, respectively; wherein, when the first drive is activated, the cold water in the production device 2 flows to the cooling fan assembly for cooling, and then flows into the cooling chamber through the first pipe. Specifically, the cooling device 1 further includes a cooling fan assembly, which is used to lower the temperature of the cold water to maintain a low temperature before flowing into the cooling chamber 111, thereby better cooling the drawing oil. The two ends of the cooling fan assembly are connected to the production device 2 of the drawing machine and the first pipe, respectively. Therefore, the production device 2 of the drawing machine, the first pipe, and the housing 11 form a flow channel for the cold water. When the first drive unit is activated, the cold water cools the production device 2 of the drawing machine, turning into hot water. The hot water flows into the cooling fan assembly and is cooled within it, turning back into cold water. The cooled water then flows through the first pipe into the cooling chamber 111, where it cools the drawing oil. Therefore, the cooling fan assembly ensures that the cold water flowing into the cooling chamber 111 is at a low temperature, better cooling the drawing oil and improving the cooling efficiency and effect of the cold water on the drawing oil.

[0052] In a specific embodiment, refer to Figure 1 and Figure 2 As shown, the cooling device 1 further includes a third pipe and a second driving component 13. The second driving component 13 is fixedly connected to the water supply port 113, and one end of the third pipe is connected to the second driving component 13. When the second driving component 13 is activated, the drawing oil enters the cooling chamber 111 along the third pipe. Specifically, the cooling device 1 further includes a third pipe and a second driving component 13. The third pipe is used to supply drawing oil into the cooling chamber 111, and the second driving component 13 serves as a power source for liquid flow, driving the flow of cold water or drawing oil. The second driving component 13 is fixedly connected to the water supply port 113, and one end of the second driving component 13 is also connected to one end of the third pipe. Therefore, the third pipe, the second driving component 13, and the cooling chamber 111 form a flow channel for the drawing oil. The other end of the third pipe is connected to the liquid storage tank of the drawing machine. The liquid storage tank refers to the place inside the drawing machine used to store high-temperature drawing oil, so that the high-temperature drawing oil can flow along the third pipe into the cooling chamber 111.

[0053] When the second drive component 13 is activated, the wire drawing oil can flow into the cooling chamber 111 along the third pipe. Therefore, the method of introducing wire drawing oil into the cooling device 1 is simple, its structure is simple, its assembly is easy, and its structural stability is high.

[0054] In an embodiment, the cooling device 1 further comprises a fourth pipeline 14 (not shown in the figure), one end of the fourth pipeline 14 being connected with the second driving member 13; wherein, when the second driving member 13 is started, the cold water in the cooling cavity 111 flows to the fourth pipeline 14 through the water supply port 113 and to the production device 2 of the wire drawing machine. Specifically, the cooling device 1 further comprises a fourth pipeline 14 for discharging cold water, the fourth pipeline 14 being located on the same side as the third pipeline, and one end of the fourth pipeline 14 and one end of the third pipeline are both connected with the second driving member 13, so that through the second driving member 13, the discharge of the cold water in the cooling cavity 111 along the fourth pipeline 14 and the suction of the drawing oil along the third pipeline are realized; the other end of the fourth pipeline 14 is connected with the production device 2 of the wire drawing machine, so that the cold water can flow along the fourth pipeline 14 to the production device 2 of the wire drawing machine, so as to recycle the cold water to further cool the production device 2 and improve the production efficiency.

[0055] When the second driving member 13 is started, the cold water in the cooling cavity 111 is sucked by the second driving member 13, and the cold water flows to the fourth pipeline 14 through the water supply port 113, and flows to the production device 2 of the wire drawing machine to cool the production device 2, thereby improving the production efficiency and service life of the wire drawing machine.

[0056] The cooling device 1 has high control over the flow of cold water, and has high structural stability. The cold water flows from the cooling cavity to the production device 2 of the wire drawing machine through the fourth pipeline 14, and the drawing oil flows from the liquid storage tank of the wire drawing machine to the cooling cavity 111 through the third pipeline, so that the flow channels of the cold water and the drawing oil are different, so as to ensure the smooth flow of the cold water and the drawing oil, ensure the quality of the cold water and the drawing oil, and improve the cooling efficiency of the production device 2; at the same time, one second driving member 13 is used as a power source to reduce the production cost.

[0057] In a specific embodiment, the water supply port 113 is further provided with a second valve (not shown in the figure), which is used to control the flow direction of the drawing oil and the cold water. Specifically, the water supply port 113 is further provided with a second valve, which is used to control the flow direction of the cold water and the drawing oil, that is, the second valve controls whether the drawing oil flows from the third pipeline to the water supply port 113 and then to the cooling cavity 111, and whether the cold water flows from the cooling cavity 111 to the backflow port 112 and then to the fourth pipeline 14, by closing or connecting the third pipeline and the water supply port 113, and by closing or connecting the fourth pipeline 14 and the water supply port 113.

[0058] When the second valve opens the communication of the third pipeline with the water supply port 113 and closes the communication of the fourth pipeline 14 with the water supply port 113, the drawing oil flows to the water supply port 113 along the third pipeline under the driving of the second driving member 13 and finally enters the cooling cavity 111; when the second valve opens the communication of the fourth pipeline 14 with the water supply port 113 and closes the communication of the third pipeline with the water supply port 113, the cold water flows to the fourth pipeline 14 from the water supply port 113 under the driving of the second driving member 13 and flows to the production device 2 of the drawing machine to cool the production device 2.

[0059] Therefore, in the embodiment, the second valve is fixedly arranged at the water supply port 113 to control the flow directions of the cold water and the drawing oil, so that the production cost is reduced, the flow directions of the cold water and the drawing oil are reliable, and the structural stability of the cooling device 1 is improved.

[0060] Referring to Figure 2 As shown in the drawings, the embodiment further provides a drawing machine, which comprises the cooling device 1, and the cooling device 1 can adopt any one of the cooling devices 1 provided by the utility model. Since the specific structure and working principle of the cooling device 1 have been described in detail in the foregoing description, the description is not repeated here for the sake of brevity.

[0061] Exemplarily, when the cooling device 1 and the production device 2 of the drawing machine are assembled, one end of the cooling fan assembly is connected with the production device 2, the other end of the cooling fan assembly is connected with the first pipeline, one end of the first pipeline is connected with the first driving member, the first driving member is fixedly arranged on the backflow port 112, and one side of the first driving member is further connected with the second pipeline; meanwhile, the second driving member 13 is connected with the water supply port 113, one side of the second driving member 13 is connected with the third pipeline, one end of the third pipeline is connected with the liquid storage tank of the drawing machine, the other side of the second driving member 13 is connected with one end of the fourth pipeline 14, and the other end of the fourth pipeline 14 is connected with one side of the production device 2.

[0062] Therefore, when the drawing machine is started, the drawing oil flows from the cooling cavity 111 to the production device 2 through the second pipeline to cool and lubricate the production device 2, and then enters the liquid storage tank of the production device 2. Under the action of the second driving member 13, the drawing oil flows from the liquid storage tank to the cooling cavity 111 through the third pipeline to cool in the cooling cavity 111. At the same time, the cold water flows from the cooling cavity 111 to the production device 2 through the fourth pipeline 14 to cool the production device 2, and then flows to the cooling fan assembly to cool in the cooling fan assembly. After cooling, under the action of the first driving member, it flows to the first pipeline and finally flows into the cooling cavity 111 to cool the drawing oil. Thus, the circulation of cold water and drawing oil in the drawing machine is realized.

[0063] Therefore, the cooling device 1 can bring the following beneficial effects by cooling the drawing oil during the production process of the drawing machine:

[0064] 1. Reduce friction heat: During the drawing process, the friction between the metal wire and the die generates a large amount of heat, which causes the bare wire to oxidize. The drawing oil quickly removes the friction heat through its cooling performance, keeping the temperature of the wire and the die within a controllable range, thereby avoiding material softening, die wear and bare wire oxidation caused by high temperature.

[0065] 2. Improve processing efficiency: Drawing oil with good cooling effect can effectively reduce temperature fluctuations during processing, making the drawing process more stable and efficient. Lower temperature not only helps to improve the smoothness of the wire surface, but also prolongs the service life of the die.

[0066] 3. Prevent material deformation: High temperature easily leads to thermal expansion and deformation of metal materials, affecting the dimensional accuracy of the finished product. By providing continuous cooling, drawing oil can help maintain the dimensional stability of the material to ensure that the product meets the requirements of precision machining.

[0067] The drawing machine in this embodiment, since it uses the cooling device 1 provided by the present application, the cooling device 1 can reduce the temperature of the drawing oil, thereby solving the problems of material softening, die wear and bare wire oxidation of the drawing machine caused by too high temperature of the drawing oil, to improve the product quality of the drawing machine production.

[0068] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
