[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention are described in detail.

[0031] Reference Figure 1 and Figure 2As shown, it shows an embodiment of the cooling device 1 and the wire drawing machine of the present invention. The cooling device 1 includes a box body 11 and a filter element 12, wherein a cooling cavity 111 is formed inside the box body 11, and a return port 112 and a water supply port 113 which are connected to the cooling cavity 111 are provided on the outer surface of the box body 11; the filter element 12 is fixed in the cooling cavity 111; wherein, cold water enters the cooling cavity 111 through the return port 112 to cool the wire drawing oil, and is discharged from the water supply port 113 through the filter element 12, and the wire drawing oil enters the cooling cavity 111 through the water supply port 113 to be cooled by the cold water and is discharged from the return port 112 through the filter element 12.

[0032] Specifically, during the production process of the wire drawing machine, a large amount of heat is generated. Most of the existing wire drawing machines cool down and lubricate the metal wire, mold, and working area by circulating wire drawing oil. During the circulation of the wire drawing oil, the temperature of the wire drawing oil gradually increases. When the temperature of the wire drawing oil is too high, it will cause the wire drawing material to overheat: the high temperature of the wire drawing oil may cause the wire drawing material to overheat, exceeding its melting point or thermal stability range. This may cause the decomposition, degradation or burning of the material, thus affecting the 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, causing it to lose its original performance and stability, which may cause the viscosity of the drawing oil to increase, oxidize, deteriorate or produce harmful substances, thus affecting the 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, resulting in an imbalance in the composition of the drawing oil, which may affect the lubricating properties and lubricating effect of the drawing oil, leading to difficulties in drawing, poor surface quality or other problems; finally, it will also lead to increased energy consumption: high temperature requires more energy to heat the drawing oil, thereby increasing energy consumption and production costs. Therefore, during the operation of the wire drawing machine, the drawing oil must also be cooled to reduce the temperature of the drawing oil, solve the problems of material softening, die wear and bare wire oxidation in the wire drawing machine, and improve product quality.

[0033] The present application provides a cooling device 1, which includes a box 11 and a filter 12. The box 11 is used to store cold water and wire drawing oil. The high thermal conductivity and high specific volume of cold water are used to exchange heat between the cold water and the wire drawing oil in the box 11, and the cold water takes away the heat of the wire drawing oil, thereby cooling the wire drawing oil. A cooling chamber 111 is formed inside the box 11, and the cooling chamber 111 is a sealed structure so that the cold water and the wire drawing oil can be stored in the cooling chamber 11. 1; the box body 11 is also provided with a return port 112 and a water supply port 113, the return port 112 and the water supply port 113 are formed by extending from the outer surface of the box body 11 toward the cooling cavity 111, and the return port 112 and the water supply port 113 are both connected to the cooling cavity 111, the return port 112 and the water supply port 113 are arranged at the top of the box body 11 at intervals, and the return port 112 is used for the outside to flow into the cooling cavity 111 The cooling chamber 111 is provided with cold water, and the return port 112 is also used for the drawing oil cooled in the cooling chamber 111 to flow to the outside through the return port 112; the water supply port 113 is used for the outside to pass high-temperature drawing oil into the cooling chamber 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 drawing oil after heat exchange can circulate in the outside; that is, the drawing oil flows into the cooling chamber 111 through the water supply port 113 , cold water flows into the cooling chamber 111 through the reflux port 112, and heat exchange occurs between the cold water and the wire drawing oil in the cooling chamber 111 to cool the wire drawing oil. The cooled wire drawing oil flows to the production device 2 through the reflux port 112 to cool and lubricate the wire, mold, and equipment; and after the cold water cools the wire drawing oil, it flows to the production device 2 through the water supply port 113 to further cool and dissipate heat from the production device 2, thereby improving the production efficiency and service life of the equipment.

[0034] At the same time, the filter element 12 is fixed in the cooling chamber 111, and the filter element 12 is used to distinguish between cold water and wire drawing oil, so that the cold water and wire drawing oil after heat exchange can flow out of the cooling chamber 111 through the water supply port 113 and the reflux port 112 respectively, so as to circulate externally; at the same time, the filter element 12 can also be used to filter impurities in the cold water and wire drawing oil, so that the cold water and wire drawing oil flowing out of the cooling chamber 111 have high cleanliness, avoid impurities entering the production device 2 to cause blockage or pollution, and avoid affecting the quality of the wire drawing oil, and ultimately affect the effect of the wire drawing oil.

[0035] Among them, when the cooling device 1 is started, the high-temperature wire drawing oil flows into the cooling chamber 111 through the water supply port 113, and the low-temperature cold water flows into the cooling chamber 111 through the reflux port 112. The cold water cools the wire drawing oil in the cooling chamber 111. The cold water in the cooling chamber 111 passes through the filter element 12 and is discharged from the water supply port 113 to the outside, while the wire drawing oil in the cooling chamber 111 passes through the filter element 12 and is discharged from the reflux port 112 to the outside, so as to realize the cooling process of the wire drawing oil by cold water.

[0036] The present application sets up the cooling device 1, and a cooling chamber 111 is formed inside the box 11 of the cooling device 1 as a heat exchange place for cold water and wire drawing oil. The high-temperature wire drawing oil is introduced into the cooling chamber 111 from the water supply port 113, and cold water is introduced into the cooling chamber 111 from the return port 112, so as to realize the heat absorption and cooling of the wire drawing oil by the cold water, and the cold water in the cooling chamber 111 flows out from the water supply port 113 through the filter element 12, and the wire drawing oil flows out from the return port 112 through the filter element 12, thereby realizing the cooling of the wire drawing oil in the box 11, and the wire drawing oil after cooling can be reused to reduce production costs; and the low temperature of the wire drawing oil is ensured. The low-temperature wire drawing oil can realize multiple functions in the production process of the wire drawing machine, the first of which is to reduce friction Heat: During the wire drawing process, the friction between the metal wire and the die will generate a lot of heat, causing oxidation of the bare wire. The wire drawing oil can quickly take away 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; secondly, it can improve processing efficiency: wire drawing oil with good cooling effect can effectively reduce temperature fluctuations during processing, making the wire drawing process more stable and efficient. Lower temperatures not only help to improve the surface finish of the wire, but also extend the service life of the die; finally, it can prevent material deformation: high temperature can easily cause thermal expansion and deformation of metal materials, affecting the dimensional accuracy of the finished product. By providing continuous cooling, wire drawing oil can help maintain the dimensional stability of the material and ensure that the product meets the requirements of precision processing.

[0037] Therefore, the cooling device cools down the wire drawing oil, thereby avoiding the problems of material softening, die wear and bare wire oxidation in the wire drawing machine, which ultimately affect the quality of the products produced by the wire drawing machine.

[0038] In a specific embodiment, refer to Figure 1 and Figure 2As shown, the filter element 12 is a filter screen, and the upper and lower ends of the filter screen are fixedly connected to the upper and lower ends of the box body 11, and the water supply port 113 and the return port 112 are respectively located on both sides of the filter screen. Specifically, the filter element 12 is used to distinguish between cold water and wire drawing oil, so that the cold water and wire 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, so as to circulate externally; at the same time, the filter element 12 can also be used to filter impurities in the cold water and wire drawing oil, so that the cold water and wire drawing oil flowing out of the cooling chamber 111 have high cleanliness, avoid impurities entering the production device 2 to cause blockage or pollution, and avoid affecting the quality of the wire drawing oil, and finally affecting the effect of the wire drawing oil.

[0039] The filter element 12 is set as a filter screen, and the filter screen is fixed inside the cooling cavity 111. The upper end and the lower end of the filter screen are fixedly connected to the upper end and the lower end of the box body 11 respectively. The filter screen is extended along the width direction of the cooling cavity 111, and the two ends of the filter screen extend to abut against the two ends of the box body 11, thereby dividing the cooling cavity 111 into two areas, the two areas are respectively located on both sides of the filter screen, and the two areas are connected to each other through the filter screen; the water supply port 113 and the return port 112 are respectively located on both sides of the filter screen, that is, the water supply port 113 and the return port 112 are connected to two areas respectively.

[0040] When cold water enters one area of ​​the cooling chamber 111 through the reflux port 112, it passes through the filter and flows toward another area of ​​the cooling chamber 111 in the direction of the water supply port 113, and finally flows to the outside 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 passes through the filter and flows toward another area of ​​the cooling chamber 111 in the direction of the reflux port 112, and finally flows to the outside through the reflux port 112.

[0041] Therefore, during the flow process, cold water and wire drawing oil need to pass through the filter net, so that impurities in the cold water and wire drawing oil are filtered on the filter net, so that the cold water and wire drawing oil flowing to the outside are clean, and impurities are prevented from entering the production device 2 to cause blockage or pollution, while avoiding affecting the quality of the wire drawing oil and ultimately affecting the effect of the wire drawing oil; at the same time, the filter net divides the cold water and wire drawing oil into two areas, so as to facilitate the cold water and wire drawing oil to flow out from the water supply port 113 and the reflux port 112 respectively.

[0042] More specifically, the filter is arranged in a direction perpendicular to the upper and lower end surfaces of the box body 11, and the filter is located on a plane where the center line of the box body 11 is located, thereby dividing the cooling chamber 111 into two areas of equal volume to improve the structural stability of the box body 11.

[0043] In one embodiment, the cooling device 1 further includes a first pipe and a first driving member (not shown in the figure), the first driving member is fixedly connected to the reflux port 112, and one end of the first pipe is connected to the first driving member; wherein, when the first driving member is started, cold water enters the cooling chamber 111 along the first pipe. Specifically, the cooling device 1 further includes a first pipe and a first driving member, the first pipe is used to pass cold water into the cooling chamber 111, and the first driving member serves as a power source for liquid flow and is used to drive the flow of cold water or wire drawing oil; the first driving member is fixedly connected to the reflux port 112, and one end of the first driving member is also connected to one end of the first pipe, so that the first pipe, the first driving member and the cooling chamber 111 form a flow channel for cold water, and the other end of the first pipe can be connected to the production device 2 of the wire drawing machine or other pipes, structural parts, etc., so that cold water can flow into the cooling chamber 111 along the first pipe.

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

[0045] In a specific embodiment, the cooling device 1 further includes a second pipe (not shown in the figure), one end of which is connected to the first driving member; wherein, when the first driving member is started, the wire drawing oil in the cooling chamber 111 flows to the second pipe through the reflux port 112 and flows to the production device 2 of the wire drawing machine. Specifically, the cooling device 1 further includes a second pipe, the second pipe is used to discharge the wire 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 to the first driving member, so that the first driving member is used to realize the cold water in the cooling chamber 111 to be drawn in along the first pipe and the wire drawing oil to be discharged along the second pipe; the other end of the second pipe is connected to the production device 2 of the wire drawing machine, so that the wire drawing oil can flow along the second pipe toward the production device 2 of the wire drawing machine, so as to recycle the wire 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 wire drawing machine, and improve product quality.

[0046] When the first driving member is started, the wire drawing oil in the cooling chamber 111 is extracted by the first driving member, flows toward the second pipeline through the reflux port 112, and circulates in the wire drawing machine to cool the wire drawing machine and lubricate the wire and the mold.

[0047] The cooling device 1 has high control over the flow of cold water and wire drawing oil, and the cooling device 1 has high structural stability. Cold water flows into the cold water chamber through the first pipe, and the wire drawing oil flows from the cooling chamber 111 to the production device 2 of the wire drawing machine through the second pipe, so that the flow channels of cold water and wire drawing oil are different, so as to ensure the smooth flow of cold water and wire drawing oil, ensure the quality of wire drawing oil and cold water, and improve the cooling efficiency of the production device 2; at the same time, a second driving member 13 is used as a power source to reduce production costs.

[0048] In one embodiment, the reflux port 112 is also provided with a first valve (not shown in the figure), and the first valve is used to control the flow direction of cold water and wire drawing oil. Specifically, the reflux port 112 is also provided with a first valve, and the first valve is used to control the flow direction of cold water and wire drawing oil, that is, the first valve controls whether cold water flows from the first pipe to the reflux port 112 and then to the cooling chamber 111 by closing or connecting the first pipe and the reflux port 112, and controls whether wire drawing oil flows from the cooling chamber 111 to the reflux port 112 and then to the second pipe by closing or connecting the second pipe and the reflux 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 is driven by the first driving component to flow along the first pipeline to the return port 112 and finally enters the cooling chamber 111; 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, wire drawing oil is driven by the first driving component to flow through the return port 112 toward the second pipeline and flow to the production device 2 of the wire drawing machine to lubricate and cool the production device 2.

[0050] Therefore, in this embodiment, the first valve is fixedly installed at the reflux port 112 to control the flow direction of cold water and drawing oil, thereby reducing production costs, 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 also includes a cooling fan assembly (not shown in the figure), and the two ends of the cooling fan assembly are respectively connected to the production device 2 of the wire drawing machine and the first pipeline; wherein, when the first driving member is started, the cold water in the production device 2 flows to the cooling fan assembly for cooling, and flows into the cold water chamber through the first pipeline. Specifically, the cooling device 1 also includes a cooling fan assembly, which is used to reduce the temperature of cold water so that the cold water remains at a low temperature before flowing into the cooling chamber 111, thereby better cooling the wire drawing oil; the two ends of the cooling fan assembly are respectively connected to the production device 2 of the wire drawing machine and the first pipeline, so that the production device 2 of the wire drawing machine, the first pipeline and the box 11 form a flow channel for cold water; when the first driving member is started, after the cold water cools the production device 2 in the production device 2 of the wire drawing machine, the cold water becomes hot water, and the hot water flows into the cooling fan assembly and cools down in the cooling fan assembly, so that the hot water becomes cold water, and the cooled cold water flows toward the first pipeline into the cooling chamber 111, and cools down the wire drawing oil in the cooling chamber 111. Therefore, the cooling fan assembly ensures that the cold water flowing into the cooling chamber 111 is in a low temperature state, so as to better cool down the wire drawing oil, thereby improving the cooling efficiency and cooling effect of the cold water on the wire drawing oil.

[0052] In a specific embodiment, refer to Figure 1 and Figure 2 As shown, the cooling device 1 also includes a third pipeline and a second driving member 13, the second driving member 13 is fixedly connected to the water supply port 113, and one end of the third pipeline is connected to the second driving member 13; wherein, when the second driving member 13 is started, the wire drawing oil enters the cooling chamber 111 along the third pipeline.

[0053] When the second driving member 13 is started, the wire drawing oil can flow along the third pipe into the cooling chamber 111. Therefore, the wire drawing oil of the cooling device 1 is introduced in a simple manner, has a simple structure, is easy to assemble, and has high structural stability.

[0054] In one embodiment, the cooling device 1 further includes a fourth pipe 14 (not shown in the figure), one end of which is connected to the second driving member 13; wherein, when the second driving member 13 is started, the cold water in the cooling chamber 111 flows to the fourth pipe 14 through the water supply port 113 and flows to the production device 2 of the wire drawing machine.

Cold water flows from the cold water chamber to the production device 2 of the wire drawing machine through the fourth pipe 14, and the wire drawing oil flows from the liquid storage tank of the wire drawing machine to the cooling chamber 111 through the third pipe, so that the flow channels of cold water and wire drawing oil are different to ensure the smooth flow of cold water and wire drawing oil, ensure the quality of wire drawing oil and cold water, and improve the cooling efficiency of the production device 2; at the same time, the second driving member 13 is used as a power source to reduce production costs.

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

[0061] Exemplarily, when assembling the cooling device 1 and the production device 2 of the wire drawing machine, one end of the cooling fan assembly is connected to the production device 2, the other end of the cooling fan assembly is connected to the first pipe, one end of the first pipe is connected to the first driving member, the first driving member is fixed on the return port 112, and one side of the first driving member is also connected to the second pipe; at the same time, the second driving member 13 is connected to the water supply port 113, one side of the second driving member 13 is connected to the third pipe, one end of the third pipe is connected to the liquid storage tank of the wire drawing machine, the other side of the second driving member 13 is connected to one end of the fourth pipe 14, and the other end of the fourth pipe 14 is connected to one side of the production device 2.

[0062] Therefore, when the wire drawing machine is started, the wire drawing oil flows from the cooling chamber 111 through the second pipeline to the production device 2 to cool and lubricate the production device 2, and then enters the liquid storage tank of the production device 2 after passing through the production device 2. Under the action of the second driving member 13, the wire drawing oil flows from the liquid storage tank to the cooling chamber 111 through the third pipeline to cool the cooling chamber 111; at the same time, cold water flows from the cooling chamber 111 through the fourth pipeline 14 to the production device 2 to cool the production device 2, and then flows to the cooling fan assembly to cool 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 chamber 111 to cool the wire drawing oil. Thereby, the cold water and wire drawing oil are circulated in the wire drawing machine.

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

[0064] 1. Reduce friction heat: During the wire drawing process, the friction between the metal wire and the die will generate a lot of heat, causing oxidation of the bare wire. The wire drawing oil can quickly take away 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: Wire drawing oil with good cooling effect can effectively reduce temperature fluctuations during processing, making the wire drawing process more stable and efficient. Lower temperature not only helps to improve the surface finish of the wire, but also prolongs the service life of the mold.

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

[0067] The wire drawing machine in this embodiment adopts the cooling device 1 provided by the present invention. The cooling device 1 can reduce the temperature of the wire drawing oil, thereby solving the problems of material softening, mold wear and bare wire oxidation caused by excessively high temperature of the wire drawing oil, so as to improve the quality of products produced by the wire drawing machine.

[0068] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
