The cost of wire drawing oil is relatively high, and it will be recycled and reused after use. After searching, the patent with application number CN202420084992.X discloses a copper wire drawing lubricating oil recovery and purification device, which continuously guides the lubricating oil used in the lubrication box into the alternating box, and filters out copper chips through the purification mechanism. At the same time, the filtered lubricating oil is guided back to the lubrication box through the recovery mechanism. When the filter screen in the alternating mechanism needs to be cleaned, the filter screen is lifted by the lifting mechanism, and another alternating mechanism is put into use before cleaning, so that the cleaning of the filter screen will not affect the use of the lubricating oil in the lubrication box.

DETAILED DESCRIPTION

[0032] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] Embodiment 1

[0034] In order to achieve the purpose of automatically cleaning the filter when the drawing oil is recovered, Figure 1-Figure 4As one embodiment of the present invention, a drawing oil cleaning and recovery device for a cable drawing machine is proposed, comprising a base 1, a mold assembly 2 is fixedly connected to the middle of the top of the base 1, a filter assembly 3 for containing and filtering the drawing oil in different areas is fixedly connected to the middle of the top of the base 1, both sides of the filter assembly 3 are equipped with height adjustment assemblies 4 for controlling the height of the bottom surface of the drawing oil containing chamber inside it, a spray assembly 5 for selectively spraying the drawing oil into different areas in the filter assembly 3 is installed on the top of the height adjustment assembly 4, the filter assembly 3 includes a containing box 31 fixedly connected to the top of the base 1, the interior of the containing box 31 is equipped with a partition plate 32 for dividing its internal space into three independent areas of the same size along the length direction, and both sides of the containing box 31 are equipped with a partition plate 32 for dividing the internal space of the containing box 31 into three independent areas of the same size along the length direction. A filter screen 33 extending into the three independent areas is provided, and a lifting frame 34 is slidably connected inside the receiving box 31 to separate the three independent areas inside into two parts along the height direction. A scraper assembly 35 for cleaning copper chips on the surface of the filter screen 33 is fixedly connected to the top of the lifting frame 34. When in use, the copper wire passes between the spray assembly 5 and the filter assembly 3, and then passes through the mold assembly 2 for wire drawing. The work of the spray assembly 5 spraying wire drawing oil is divided into two steps. The first step is to select any one or any two areas of the three independent areas in the receiving box 31 for spraying. The second step is to stop the spraying area in step one, and then select at least one area from the remaining areas in the receiving box 31 for spraying, and finally repeat the above two steps.

[0035] When the spraying component 5 sprays the wire drawing oil into the containing box 31, the wire drawing oil sprays onto the copper wire passing below, and then falls into the containing box 31. The height adjustment component 4 pushes the lifting frame 34 to a higher position, and the weight of the wire drawing oil pushes the lifting frame 34 to drop a certain height. At this time, the lifting frame 34 where the wire drawing oil falls is defined as area 1. Then, the wire drawing oil on the lifting frame 34 slides along the surface and passes through the filter 33. The wire drawing oil therein is recovered after passing through the height adjustment component 4, while the copper chips are blocked on the filter 33, and then Then, the spray position of the spray component 5 is replaced so that the wire drawing oil is sprayed onto the copper wires above other lifting frames 34, and the wire drawing oil drops from the copper wires to the lifting frames 34. At this time, the lifting frames 34 where the wire drawing oil drops are specified as area two. The lifting frames 34 in area two are lowered for a certain height due to the weight of the wire drawing oil dropped thereon after being sprayed by the spray component 5, while the lifting frames 34 in area one are reduced in weight due to the wire drawing oil moving from the filter 33 to the height adjustment component 4. The height adjustment component 4 pushes the lifting frames 34 in area one to rise again.

[0036] Then, the spray position of the spray component 5 is changed, so that the lifting frames 34 at different positions can be continuously lifted and lowered by utilizing the weight change of the wire drawing oil above them. When the lifting frames 34 are lifted, the lifting frames 34 scrape against the surface of the filter 33 to scrape off the copper chips attached to the surface of the filter 33, so that the copper chips attached to the surface of the filter 33 fall on the lifting frames 34. It is only necessary to control the spray component 5 to continuously change the spray position, so that the lifting frames 34 at different positions can be continuously lifted and lowered by utilizing the weight change of the wire drawing oil on them, and the copper chips attached to the surface of the filter 33 can be removed by scraping between the lifted lifting frames 34 and the filter 33. There is no need for the staff to clean the copper chips on the filter 33, which reduces the steps of cleaning the filter 33 when the wire drawing oil is recovered, reduces the workload, and can also prevent the problem of copper chips clogging the filter due to the staff's failure to clean the filter in time.

[0037] In order to improve the cleaning ability of the copper scraps attached to the filter screen 33, refer to Figure 3 and Figure 4 The scraper assembly 35 includes an elastic plate 351 fixedly connected to the top of the lifting frame 34, a slider 352 slidably connected to the filter screen 33 is fixedly connected to the top of the elastic plate 351, a semicircular groove is provided on the side of the slider 352 close to the filter screen 33, a semi-circular cylinder 6 adapted to the slider 352 is fixedly connected to the side of the filter screen 33 close to the slider 352, and the slider 352 is slidably connected to the semi-circular cylinder 6. When in use, the elastic plate 351 presses the slider 352 on the surface of the filter screen 33. When the lifting frame 34 is lifted or lowered, the slider 352 is driven to lift or lower through the elastic plate 351. When the slider 352 contacts the filter screen 33, the slider 352 rubs against the filter screen 33 to push the surface of the filter screen 33 The attached copper chips are scraped off. When the slider 352 slides to the semi-cylinder 6, the slider 352 slides onto the semi-cylinder 6 and separates from the filter 33. In this process, the slider 352 squeezes and bends the elastic plate 351 until the slider 352 passes through the semi-cylinder 6. Then the slider 352 is pushed by the elastic plate 351 to collide with the filter 33, causing the filter 33 to vibrate and remove the copper chips attached to its surface. Then the slider 352 continues to slide along the filter 33 to scrape off the copper chips. The scraping and vibration of the slider 352 can be used to assist the lifting frame 34 in cleaning the copper chips on the surface of the filter 33, thereby improving the effect of cleaning the copper chips on the surface of the filter 33 and reducing the residual amount of copper chips on the surface of the filter 33 after cleaning.

[0038] In order to improve the sealing between the lifting frame 34 and the containing box 31, the wire drawing oil on the top of the lifting frame 34 is prevented from leaking from the gap between the lifting frame 34 and the containing box 31. Figure 3The lifting frame 34 is made of metal. The inner bottom of the receiving box 31 is fixedly connected with an inclined airbag column 7 that supports the lifting frame 34. The bottom of the inclined airbag column 7 is fixedly connected with the receiving box 31. A longitudinal airbag column 8 is fixedly connected with the inner bottom of the receiving box 31. A plurality of filling blocks 9 are fixedly connected with the inner bottom of the receiving box 31. The lifting frame 34 made of metal is selected. The precision of metal processing is used to ensure the fit between the lifting frame 34 and the receiving box 31, thereby reducing the possibility of wire drawing oil leaking from the gap between the lifting frame 34 and the receiving box 31. The lifting frame 34 made of metal is not easy to rise by buoyancy. The inclined airbag column 7 and the longitudinal airbag column 8 are installed at the bottom of the lifting frame 34 for auxiliary support, which are used to assist in supporting the lifting frame 34 made of metal, and to raise the lifting frame 34 together with the buoyancy of the water below the lifting frame 34. Since the width of the storage box 31 is large, the capacity is also large. When the lifting frame 34 is raised, the amount of water that needs to be filled below it is large. In order to reduce the amount of water that needs to be filled below it when the lifting frame 34 is raised, a filling block 9 is installed inside the storage box 31, which reduces the space inside the storage box 31 and also limits the lowest position of the lifting frame 34.

[0039] Embodiment 2

[0040] In order to adjust the height of the lifting frame 34, the lifting frame 34 is lowered when there is drawing oil above the lifting frame 34, and the lifting frame 34 is lowered when there is no drawing oil above the lifting frame 34, so as to control the lifting of the lifting frame 34 according to whether there is drawing oil on the lifting frame 34 to scrape off the copper chips attached to the surface of the filter 33, so as to achieve the purpose of automatically cleaning the copper chips on the surface of the filter 33. Figure 1-Figure 5 On the basis of the first embodiment, the height adjustment component 4 includes a bracket 41 fixedly connected to one side of the base 1, a water tank 42 is fixedly connected to the top of the bracket 41, a guide groove penetrating the water tank 42 is provided on the side of the water tank 42 away from the filter screen 33, the bottom of the guide groove is an inclined surface, a water inlet is provided on the top of the water tank 42, a scale 43 extending to the inside of the water inlet is fixedly connected to the inside of the water tank 42, and the water tank 42 is connected to the three independent areas of the receiving box 31 through pipes. When in use, water is added to the water tank 42 from the water inlet. Due to the principle of communicating vessels, the water in the water tank 42 enters the containing box 31 after passing through the pipe, and pushes the lifting frame 34 to rise under the combined action of buoyancy, the inclined airbag column 7 and the longitudinal airbag column 8, until the lifting frame 34 rises to the same height as the liquid level inside the water tank 42. The liquid level of the water in the water tank 42 is judged according to the scale 43, and the starting height of the lifting frame 34 can be controlled by controlling the liquid level in the water tank 42 after adding water to the water tank 42.

[0041] When the wire drawing oil falls onto the lifting frame 34, the weight of the wire drawing oil pushes the lifting frame 34 down, and the water under the lifting frame 34 enters the water tank 42, causing the liquid level inside the water tank 42 to rise until the wire drawing oil on the lifting frame 34 is discharged from the filter 33. At this time, the water in the water tank 42 re-enters the containing box 31, pushing the lifting frame 34 to rise to the starting height. The height of the lifting frame 34 can be controlled by the principle of communicating vessels, and the lifting frame 34 can be driven to descend when the wire drawing oil moves to the lifting frame 34, and the lifting frame 34 can be driven to rise again when the wire drawing oil is discharged from the lifting frame 34, thereby realizing the purpose of flexibly controlling the lifting and lowering of the lifting frame 34 according to the weight of the wire drawing oil on the lifting frame 34, and scraping off the copper chips attached to the surface of the filter 33 during the lifting process.

[0042] After the wire drawing oil lubricates and cools the copper wire, it will be heated up by the heat on the copper wire. Since the wire drawing oil on the lifting frame 34 passes through the filter screen 33 and moves to the guide groove of the water storage tank 42, and then flows along the inclined surface at the bottom of the guide groove, the wire drawing oil is in contact with the water storage tank 42 at this time, and its heat can be cooled by the water inside the water storage tank 42. After the heat in the wire drawing oil is transferred to the water in the water storage tank 42, the temperature of the water in the lower half of the water storage tank 42 gradually increases. Then, under the free diffusion of water, the water in the lower half of the water storage tank 42 has a lower density due to the higher temperature. The water with higher regional temperature will gradually move to the upper area of ​​the water storage tank 42 near the water inlet, dissipating the heat outward from the water inlet, while the water with lower temperature originally in the upper area of ​​the water storage tank 42 will flow to the lower area of ​​the water storage tank 42, and continue to cool the wire drawing oil passing through the guide groove, which can cool the recovered wire drawing oil and facilitate the reuse of the recovered wire drawing oil. At the same time, the circulation of water for water cooling of the wire drawing oil is realized, and the water with lower temperature is kept in contact with the wire drawing oil, while the water with higher temperature moves to a position away from the wire drawing oil to dissipate heat, thereby improving the cooling effect on the wire drawing oil.

[0043] In order to guide the recovered wire drawing oil to the designated location and facilitate the reuse of the recovered wire drawing oil, refer to Figure 5 A tilted frame 10 for accommodating the wire drawing oil flowing out of the guide groove is fixedly connected to the side of the water tank 42 away from the receiving box 31. A plurality of support blocks 11 are fixedly connected between the bottom of the tilted frame 10 and the bracket 41. A recovery groove for accommodating the wire drawing oil after filtering the copper chips is opened on the top of the base 1. A guide frame 12 extending to the inside of the recovery groove is connected to one end of the bottom of the tilted frame 10. When in use, the wire drawing oil on the lifting frame 34 passes through the filter screen 33 and moves into the guide groove of the water tank 42, and then flows into the tilted frame 10 along the inclined surface of the guide groove, and then flows into the recovery groove on the base 1 after passing through the guide frame 12 along the tilted frame 10. The staff only needs to transport the wire drawing oil in the recovery groove to the spray assembly 5 for reuse.

[0044] Embodiment 3

[0045] In order to conveniently control the spraying position of the wire drawing oil on the copper wire, after the spraying position changes, the lifting frame 34 is automatically controlled to move and scrape off the copper chips attached to the surface of the filter screen 33 according to the weight change of the wire drawing oil on the lifting frame 34. Figure 1-Figure 7 On the basis of the first embodiment, the spray assembly 5 includes a support frame 51 fixedly connected to the top of the water storage tank 42, and the top of the support frame 51 is fixedly connected with spray pipes 52 corresponding to the three independent areas of the receiving box 31. The three spray pipes 52 are connected with a delivery pipe 53 for delivering wire drawing oil thereto. An electromagnetic valve 54 is installed at one end of the spray pipe 52 close to the delivery pipe 53. When in use, the wire drawing oil is delivered to different spray pipes 52 through the delivery pipe 53. When it is necessary to spray different areas of the receiving box 31, the electromagnetic valve 54 in the corresponding area is controlled to open, while the electromagnetic valves 54 in other areas are closed, so that the wire drawing oil in the delivery pipe 53 is delivered to the spray pipe 52 in the corresponding area, so that the wire drawing oil can be controlled to be sprayed to different areas of the receiving box 31 according to needs, so as to realize the automatic control of the position of spraying the wire drawing oil, and then control the lifting frame 34 in different areas inside the receiving box 31 to automatically lift and scrape off the copper chips attached to the surface of the filter screen 33, thereby reducing the workload of the staff and realizing the automation of wire drawing oil recovery.

[0046] Different numbers of copper wires can be drawn at the same time as needed. When the number of copper wires to be drawn is small, only the spray pipe 52 needs to spray the drawing oil above the copper wires. Spraying at all positions of the spray pipe 52 at the same time will waste the drawing oil. In order to flexibly adjust the spraying amount according to the specific situation of the copper wires to be drawn, refer to Figure 6 and Figure 7 The bottom of the spray pipe 52 is connected to multiple longitudinal tubes 13, and a sealing plug 14 is provided at one end of the longitudinal tube 13 away from the spray pipe 52. The wire drawing oil in the spray pipe 52 is sprayed from the longitudinal tube 13 to the copper wire below. When there is no copper wire for wire drawing below the longitudinal tube 13, the sealing plug 14 can be used to block the longitudinal tube 13 without copper wire below. During spraying, only the longitudinal tube 13 without the sealing plug 14 at the bottom will be sprayed with the wire drawing oil. The spraying position can be flexibly adjusted according to the specific number of copper wires to be drawn, thereby reducing the waste caused by spraying the wire drawing oil at the place where there is no copper wire.

[0047] Embodiment 4

[0048] In order to draw a large number of copper wires at the same time and to draw the copper wires to different diameters, refer to Figure 1-Figure 8On the basis of the first embodiment, the mold assembly 2 includes a bottom plate 21 fixedly connected to the base 1, a bolt with one end movably extending to the inside of the base 1 is provided on the top of the bottom plate 21, a longitudinal plate 22 is fixedly connected to the top of the bottom plate 21, and a placement groove corresponding to the longitudinal tube 13 is opened on one side of the longitudinal plate 22, and a mold 23 with a hole in the middle is provided in the placement groove. The mold 23 with different apertures can be selected according to the diameter of the copper wire to be drawn, and then the mold 23 is placed in the placement groove on the longitudinal plate 22, and a corresponding number of molds are placed according to the number of copper wires to be drawn at the same time, and then one end of the copper wire is passed through the mold 23, and then the copper wire is pulled through the mold 23. During this process, the spray assembly 5 continuously sprays drawing oil on the copper wire, and the mold 23 can be adjusted according to the needs of the specific drawing diameter and the number of wires to be drawn to meet the needs of drawing the copper wire into different diameters.
