Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal processing, in particular to a circulating system of aluminum wire drawing liquid. BACKGROUND

[0002] Pure oil aluminum drawing lubricating oil is mainly composed of base oil (usually mineral oil), extreme pressure anti-wear agent and other functional additives. Under high temperature friction conditions, its composition is easy to change and produce corresponding substances. When the working temperature exceeds a certain range, the base oil will evaporate or pyrolyze to generate volatile organic compounds such as alkanes, alkenes and aromatic hydrocarbons. The extreme pressure anti-wear agent containing phosphorus, sulfur and chlorine may decompose at high temperature to release a small amount of irritating or toxic gases such as hydrogen chloride, hydrogen sulfide and hydrogen phosphide. Additives such as antioxidants and defoamers may also undergo complex decomposition reactions under high temperature conditions to generate corresponding products. At the same time, high-speed friction and agitation can form a large number of micron-sized liquid oil droplets suspended in the air, forming visible oil mist.

[0003] After a period of wire drawing work, a large amount of aluminum ash will accumulate in the pure oil aluminum drawing lubricating oil, and the lubricating oil will change from the original brownish color to grayish black. Although the centrifuge can partially remove the aluminum mud, the smaller particles of aluminum powder cannot be removed and still remain suspended in the lubricating oil. When the worker operates the wire drawing equipment to start the machine and wear the mold, the lubricating oil will leak to a certain extent, and the oil will be difficult to clean up once it leaks and will affect the surrounding environment.

[0004] When the oil-based aluminum drawing oil is working, a large amount of friction heat will be generated due to the drawing of aluminum rods in the mold. These heat will cause the temperature of the lubricating oil to rise rapidly. Once the temperature rises and exceeds the working temperature, it will be difficult to reduce. Because the oil-based lubricating oil has large viscosity and slow flow rate, the heat exchanger cannot remove so much heat to achieve better cooling effect. When the temperature further rises to the flash point of the oil, the phenomenon of fire will occur.

[0005] The pure oil lubricant needs at least a certain amount to make the wire drawing machine work normally, and this amount cannot be used when the ash content of the lubricating oil exceeds a certain value, and only new oil can be replaced.

[0006] When drawing profiled wire, due to the shape characteristics of single wire, the direction of each pass mold must be consistent, so the outlet mold cannot rotate like the round wire, which causes the aluminum ash to flow out unevenly and block the mold, causing frequent wire breakage during production or aggravating the wear of the mold.

DETAILED DESCRIPTION

[0028] In order to make the structure of the present application and the function characteristics and advantages achieved more easily understood, the preferred embodiments of the present application are described in detail below, and the drawings are as follows: Embodiment one: As shown in the drawings, the present application provides a circulating system of aluminum wire drawing liquid, comprising: Figures 1 to 7 wire drawing equipment 1 with outlet die 11 and immersion liquid tank 12, after the aluminum rod is drawn into the immersion liquid tank 12, it is formed after sizing from the outlet die 11; wire drawing liquid pool 2, a filter 4 is arranged in the wire drawing liquid pool 2, the filter 4 is communicated with the immersion liquid tank 12 through circulation pipe one 5, a double-plate heat exchanger 7 is connected on the circulation pipe one 5, the immersion liquid tank 12 is communicated with the wire drawing liquid pool 2 through return pipe 9; cooling system 3 connected with the heat exchanger 7 through circulation pipe two 6; The filter 4 has a plurality of continuous filtering mechanisms 41, the continuous filtering mechanism 41 is configured to trigger the continuous filtering mechanism 41 to rotate to switch the new filtering structure 42 when the water level in the filter 4 rises, so as to filter the aluminum powder in the wire drawing liquid pool 2, and the filtered wire drawing liquid is recirculated to the immersion liquid tank 12 of the wire drawing equipment 1 through the circulation pipe one 5, so as to realize the purification circulation of the wire drawing liquid, good lubrication performance, and smooth surface of the aluminum wire. Referring to

[0029] , the filter 4 includes a tank body 43 provided with an opening at the bottom, the continuous filtering mechanism 41 includes a rotating filter cavity 411, a driven roller one 412 and a driven roller two 413, the rotating filter cavity 411 is rotatably arranged in the tank body 43, the driven roller one 412 and the driven roller two 413 are rotatably arranged in the tank body 43 and located on both sides of the upper end of the rotating filter cavity 411, so that the filtering structure 42 moving from the driven roller one 412 passes through the rotating filter cavity 411 and then passes through the driven roller two 413, so that the rotating filter cavity 411 and the filtering structure 42 form a circular filter cavity structure, the wire drawing liquid in the circular filter cavity structure is filtered wire drawing liquid, that is, lubricating oil after filtering aluminum powder. Figures 3 to 5

[0030] Referring to Figure 5 ​The hollow tube 4111 is provided with a plurality of through holes 4112. The circulation pipe one 5 is in rotational communication with the hollow tube 4111 through a sealing bearing. The rotating filter chamber 411 is provided with a circular plate 4113 at both ends. The two circular plates 4113 are connected through the hollow tube 4111. One end of the hollow tube 4111 is a closed structure, and the other end is connected with the circulation pipe one 5 through a sealing bearing. The filtering structure 42 is arranged around the circular plate 4113, so that the hollow cavity between the filtering structure 42 and the circular plate 4113 forms a circular filter chamber structure. The filtered wire drawing liquid can enter the circulation pipe one 5 through the hollow tube 4111 in the middle of the circular filter chamber structure, and then return to the liquid tank 12 by pumping.

[0031] Specifically, the circular plate 4113 has a certain thickness, so that the filtering structure 42 arranged thereon can be stably moved thereon and drive the rotating filter chamber 411 to rotate in the wire drawing liquid pool 2.

[0032] Referring to Figures 5 to 7 The continuous filtering mechanism 41 further comprises a driving motor 414 and at least two discharge rollers 415. The driving motor 414 is arranged on one side of the box body 43. The discharge rollers 415 are arranged at the discharge port of the box body 43. The driving motor 414 is in transmission connection with one of the discharge rollers 415 through a speed reducer. The end of the discharge roller 415 is in meshing transmission through the linkage gear 46. The driving motor 414 drives one of the discharge rollers 415 to rotate, and drives the other discharge roller 415 to perform synchronous reverse motion through the linkage gear 46 engaged at the end, so that the filtering structure 42 clamped therebetween moves to switch the new filtering structure 42 of the circular filter chamber structure under the rotation of the discharge roller 415.

[0033] Further, the speed reducer at the output end of the driving motor 414 can be in transmission connection with one end of the hollow tube 4111 through a sprocket and a chain, so as to drive the rotating filter chamber 411 to rotate in the box body 43 when the driving motor 414 works. Further, the end of one of the discharge rollers 415 can also be in transmission connection with one end of the hollow tube 4111 through a sprocket and a chain, so as to drive the rotating filter chamber 411 to rotate in the box body 43.

[0034] Referring to Figure 3 An inclined support frame 44 is arranged on one side of the box body 43. A rotating rod is arranged on the support frame 44. The filtering structure 42 is a 800-mesh non-woven fabric in a winding drum structure. The filtering structure 42 is rotatably sleeved on the rotating rod and is arranged around the driven roller one 412 through the inlet on one side of the box body 43. Further, the upper portions of the two ends of the support frame 44 are inclined or vertical and are provided with a slotted groove for placing the rotating rod. A rotating ring with an opening is rotatably arranged on the slotted groove, so as to facilitate closing and opening of the slotted groove.

[0035] Specifically, the non-woven fabric of the 800 purpose can effectively filter the aluminum powder while retaining the original lubricating oil. The liquid level of the drawing liquid on the non-woven fabric will rise, at which time the liquid level sensor provided in the filter 4 is subjected to the buoyancy of the rising water level, which will cause the driving motor 414 to be connected to the circuit to drive the two discharge rollers 415 to rotate to drive the filter structure 42 of the non-woven fabric to rotate and switch, thereby continuously using new non-woven fabric for aluminum powder filtration.

[0036] Further, referring to Figure 5 , the top of the box 43 is provided with an openable separation net, so as to view the drawing liquid filtration in the circular filter cavity structure in the box 43 by opening the separation net.

[0037] Further, referring to Figure 4 , the box 43 is provided with a storage box below the discharge roller 415, so as to collect the non-woven fabric coming out of the box 43.

[0038] Referring to Figure 1 , the cooling system 3 includes a cooling pool 31 and a cooling tower 32, and the cooling tower 32 is arranged at the upper portion of the cooling pool 31, and the cooling pool 31 is communicated with the cooling tower 32 through the circulation pipe two 6. The cooling water in the cooling pool 31 is deionized water. The aluminum drawing lubricating liquid used is formed by mixing 1:3 of the water-based aluminum drawing crude oil and the deionized water. After mixing, the odor of the crude oil is basically covered. After the temperature rises, the main emitted water molecules also do not have obvious irritating odor, which is friendly to the environment. At the same time, the water-based lubricating liquid has a cleaning function, which can take away and clean the aluminum ash remaining in the equipment. Therefore, the workers are clean, and the machine table is clean and tidy.

[0039] The circulation pipe one 5 and the circulation pipe two 6 are communicated with the water pump 8, and the water pump 8 of a certain power is used to draw the drawing liquid from the drawing liquid pool 2 into the drawing equipment 1, and then the drawing liquid is returned to the filter 4 through the heat exchanger 7, and then the drawing liquid is filtered into the drawing liquid pool 2.

[0040] The water pump 8 of a certain power is used to draw the cooling water from the cooling pool 31 to the circulation pipe to the heat exchanger 7, and the double-plate heat exchanger 7 is used to efficiently transfer the heat of the drawing liquid to the cooling water, so as to reduce the temperature of the drawing liquid itself. The deionized cooling water used can be used for a long time without causing fouling inside the heat exchanger 7, so as to cause blockage and loss of heat exchange efficiency. Then, the cooling water is returned to the cooling tower 32 for circulation. The cooling tower 32 can pass the cooling water with the temperature rising through the water flow refiner at the top of the tower, and a small amount of water will evaporate in the falling process, so as to transfer heat to the air to reduce the temperature of the cooling water.

[0041] The water-based aluminum wire drawing lubricant of the present application will produce aluminum powder in the process of aluminum wire drawing, which will reduce the lubricating performance when accumulated to a certain extent. Therefore, a filter structure 42 with 800-mesh non-woven fabric is used to filter the aluminum powder, filtering aluminum powder particles and impurities above 10 um (because the oil droplet diameter in the drawing liquid is generally 0.1-10 um) while retaining the lubricating oil, ensuring that the lubricating performance of the water-based lubricant is not affected and prolonging the service life. The filter 4 uses a liquid level sensor for automatic paper feeding.

[0042] Referring to Figure 1 and Figure 10 , the drawing liquid pool 2 includes a sunken cement tank and a stainless steel pool 21, which is arranged in the cement tank. The stainless steel pool is welded with 304 stainless steel plate with a thickness of 4 mm and is reinforced with stainless steel rectangular square tubes around to prevent thermal expansion and contraction deformation and weld cracking of the stainless steel pool due to temperature changes during the working process of the drawing liquid.

[0043] The working principle of the present application is as follows: after the aluminum rod is drawn into the immersion tank 12 and is sized from the outlet die 11, the drawing liquid is pumped into the immersion tank 12 through the circulation pipe one 5 to lubricate, clean and remove heat from the aluminum rod. The drawing liquid containing aluminum powder in the immersion tank 12 is returned to the drawing liquid pool 2 through the return pipe 9. The drawing liquid in the drawing liquid pool 2 enters the box 43 through the opening at the bottom of the filter 4 box 43, and then enters the circular filter cavity structure composed of the rotating filter cavity 411, the driven roller one 412 and the driven roller two 413, and the filter structure 42, and then enters the hollow pipe 4111 through the through hole 4112 on the hollow pipe 4111, and then is pumped into the immersion tank 12 through the circulation pipe one 5. The heat exchanger 7 on the circulation pipe one 5 cools the drawing liquid, and the removed heat is circulated through the circulation pipe two 6 to the cooling system.

[0044] Example two: As another embodiment of the present application, as Figure 2As shown, the outlet die 11 includes a sizing die 111 and a die seat 112, the die seat 112 is mounted at one end of the liquid tank 12, and the sizing die 111 is arranged on the die seat 112; a plurality of grooves 113 are arranged on the die seat 112, and the grooves 113 are attached to the back of the sizing die 111. During the drawing process, the drawing liquid will slowly flow out through the grooves 113 and wet the accumulated aluminum powder at the outlet position and flow out, which can avoid the aluminum powder drawn out everywhere and avoid the accumulation of aluminum powder to block the die hole. The main function of the drawing liquid is lubrication, cleaning and heat removal. The metal rod needs lubricant to lubricate at the die opening of the sizing die 111 during drawing, otherwise the drawing cannot proceed smoothly. When the drawing liquid passes through the sizing die 111, a certain thickness of oil film is formed between the die opening and the rod, thereby reducing the friction coefficient, and the aluminum powder generated during the drawing process will be carried away and filtered in the drawing liquid.

[0045] Example three: As another embodiment of the present application, as shown in Figure 8 The continuous filtering mechanism 41 further includes driven roller three 416 and driven roller four 417 rotatably arranged in the box 43, the driven roller three 416 is rotatably arranged vertically above the driven roller one 412, and the driven roller four 417 is rotatably arranged vertically above the driven roller two 413. The four discharge rollers 415 are meshed and driven by the linkage gear 46. The circular plate 4113 is provided with a plurality of supporting rollers 418 arranged circumferentially. The two filtering structures 42 are wound on the driven roller three 416, the supporting rollers 418 and the driven roller four 417 in sequence, and come out from the vertical gap between the four discharge rollers 415. The other filtering structures 42 are wound on the driven roller one 412, the circular plate 4113 and the driven roller two 413 in sequence, and come out from the lower horizontal gap between the four discharge rollers 415.

[0046] Specifically, the four discharge rollers 415 include a first discharge roller 4151, a second discharge roller 4152, a third discharge roller 4153 and a fourth discharge roller 4154. One end of the first discharge roller 4151 is connected with the transmission of the output end of the driving motor 414. The ends of the second discharge roller 4152 and the third discharge roller 4153 are respectively connected with the end of the first discharge roller 4151 through the linkage gear 46. The end of the fourth discharge roller 4154 is connected with the third discharge roller 4153 through the linkage gear 46. When the first discharge roller 4151 rotates, it can drive the second discharge roller 4152 and the third discharge roller 4153 to rotate in the opposite direction synchronously. The fourth discharge roller 4154 rotates in the same direction with the first discharge roller 4151, so as to discharge the two filtering structures 42 at the same time, and switch the new filtering structure 42 on the filter cavity 411 at the same time.

[0047] Further, referring to Figure 8The two filtering structures 42 include a first filtering structure 421 and a second filtering structure 422. The first filtering structure 421 is arranged around the driven roller one 412, the circular plate 4113, the driven roller two 413, the third discharge roller 4153 and the fourth discharge roller 4154. The second filtering structure 422 is arranged around the driven roller three 416, the supporting roller 418, the driven roller four 417, the first discharge roller 4151 and the second discharge roller 4152. The filtering structure 42 forms two filtering areas in the rotating filter cavity 411, i.e. an annular filtering cavity with a mesh size of 800 and a secondary filtering cavity with a mesh size less than 800. Specifically, the filtering structure 42 can be double 800, i.e. the first filtering structure 421 is 800 non-woven fabric and the second filtering structure 422 is less than or equal to 800. Further, the first filtering structure 421 can be greater than 800 non-woven fabric and the second filtering structure 422 is 800 non-woven fabric.

[0048] Embodiment four: As another embodiment of the present application, as shown in Figure 9 The second discharge roller 4152 is rotatably connected with an annular limiting member at both ends. The annular limiting member is slidably arranged in a limiting sliding groove on the mounting rack on both sides of the box 43. The first discharge roller 4151 and the second discharge roller 4152 are rotatably arranged on the mounting rack. An adjusting member 45 is penetratingly arranged at one end of the limiting sliding groove. The adjusting member 45 is a screw rod or an electric telescopic rod. One end of the adjusting member 45 is rotatably connected or fixedly connected with the annular limiting member. The distance between the first discharge roller 4151 and the second discharge roller 4152 is adjusted by the adjusting member 45. When it is needed to separately control the movement of the first filtering structure 421, the adjusting member 45 is rotated or retracted to move the second discharge roller 4152 away from the first discharge roller 4151. At this time, the pressing roller 419 arranged above the driven roller four 417 in the box 43 is lowered to press the second filtering structure 422 under the action of the electric telescopic rod 47. The driving motor 414 is started to control the first discharge roller 4151 to work to drive the third discharge roller 4153 to move. Since the second discharge roller 4152 is away from the first discharge roller 4151, the linkage gear 46 on the second discharge roller 4152 is also out of engagement to realize the separate switching of the first filtering structure 421. When it is needed to switch the new filtering structure 42 with the first filtering structure 421 and the second filtering structure 422, the adjusting member 45 drives the second discharge roller 4152 to move to engage with the linkage gear 46 on the first discharge roller 4151. The pressing roller 419 is raised to release the movement freedom of the second filtering structure 422 under the action of the electric telescopic rod 47. At this time, the driving motor 414 works to drive the first discharge roller 4151 to rotate the second discharge roller 4152 and the third discharge roller 4153 to move to switch the new filtering structure 42.

[0049] Further, referring to Figure 9 The roller 418 can be replaced by a ring-shaped protrusion 4114 to stably support the second filter structure 422, so that the second filter structure 422 can stably move in the rotating filter cavity 411 under the driving of the discharging roller 415.

[0050] The embodiment realizes secondary and continuous filtration of the drawing liquid by arranging the double-layer filter structure 42 and the multiple filter cavities composed of the double-layer filter structure 42, has high filtration efficiency, and is convenient for replacing the new filter structure 42, so that the filter structure 42 can continuously perform the filtration work without stopping the machine to disassemble and replace the internal filter structure 42, and only needs to connect the non-woven fabric of the filter structure 42 at the end of the service life with the non-woven fabric of the new filter structure 42.

[0051] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present application or modify it into equivalent embodiments with equivalent changes without departing from the scope of the technical solution of the present application. Therefore, any modification, equivalent change and modification made to the above embodiment according to the technical solution of the present application, which does not depart from the content of the technical solution of the present application, belongs to the protection scope of the technical solution.
