[0002] Drawing machines are industrial equipment composed of mechanical equipment, lubrication equipment, electrical equipment, hydraulic and pneumatic systems, etc. They are used to draw metal materials at room temperature. The working principle is to apply pulling force to the metal blank to make it pass through the die hole to obtain plastic forming of products with the same size and shape as the die hole.

[0003] For example, in the prior art, there is a double-station copper rod high-efficiency lubrication drawing processing device with a publication number of CN114769343A. Although the lubrication component in the device can achieve the self-lubrication effect before drawing, it lacks a structure for removing impurities from the surface of the copper rod before oiling, and the viscosity of the lubricating oil itself makes it easy for particulate impurities on the surface of the copper rod to enter the drawing die with the copper rod, resulting in the formation of pits on the surface of the copper rod after drawing, which affects the quality of the drawing process; in addition, it can only realize the application of lubricating oil, but cannot intercept the excessive application of lubricating oil, which easily leads to the problem of excess lubricating oil entering the drawing die, causing the lubricating oil to flow everywhere and cause waste.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1-Figure 7As shown, the copper rod processing and drawing device based on the self-lubricating mechanism in this embodiment includes a base 1, a processing cylinder 11 is fixedly connected to the top of the base 1, and is used for removing impurities and lubricating the surface of the copper rod, and through holes 1 are symmetrically opened on both sides of the processing cylinder 11, for the copper rod to pass through and out of the processing cylinder 11, and a rotating disk 12 is rotatably connected inside the processing cylinder 11, and a through hole 2 which is coaxial with the through hole is opened on the rotating disk 12, for the copper rod to pass through;

[0036] The rotating disc 12 divides the interior of the treatment tube 11 into a cleaning chamber and an oiling chamber. The rotating disc 12 and the treatment tube 11 are sealed and rotatably connected to prevent the lubricating oil in the oiling chamber from entering the cleaning chamber, which would cause the impurities to be difficult to discharge and the lubricating oil to be wasted. The cleaning component 2 and the oiling component 3 are respectively arranged on both sides of the rotating disc 12.

[0037] The impurity removal component 2 is arranged in the impurity removal chamber, the oiling component 3 is arranged in the oiling chamber, and the oiling chamber is filled with lubricating oil, so that the oiling component 3 cooperates with the impurity removal component 2 to extract and spray the lubricating oil, thereby realizing the effect of self-lubrication and drawing. A drawing component 4 is arranged on the top of the base 1, which is used for continuous drawing processing of copper rods in and out, and a fixing frame 13 is arranged between the processing cylinder 11 and the drawing component 4, and a drawing die 14 is fixedly installed on the fixing frame 13.

[0038] The impurity removal component 2 includes a left mounting frame 21 rotatably mounted on the processing cylinder 11, and a right mounting frame 22 is fixedly mounted on the rotating disk 12. The left mounting frame 21 and the right mounting frame 22 are coaxially arranged to achieve a stable rotation effect, and a plurality of abutment seats 23 are arranged between the right mounting frame 22 and the left mounting frame 21 for centering and clamping the copper rod, thereby achieving efficient impurity removal and oiling effects. A Z-shaped plate 24 is fixedly connected to the abutment seat 23, and a cleaning brush 25 is fixedly connected to the Z-shaped plate 24. During the circumferential rotation of the cleaning brush 25 carried by the plurality of Z-shaped plates 24, impurities on the surface of the copper rod are cleaned.

[0039] The oiling assembly 3 includes an oil suction hose 31 and an oil spray pipe 32 fixedly mounted on the Z-shaped plate 24. The oil suction hose 31 extracts the lubricating oil in the treatment cylinder 11, and the oil spray pipe 32 sprays the extracted lubricating oil onto the surface of the cleaned copper rod. An oil absorption sponge 33 is provided on the Z-shaped plate 24 on the side of the oil spray pipe 32 away from the rotating disk 12. The excess lubricating oil on the surface of the copper rod is adsorbed by the oil absorption sponge 33 that is in contact with the copper rod.

[0040] A plurality of connecting scrapers 26 are fixedly connected between the left mounting frame 21 and the right mounting frame 22. On the one hand, they are used to connect the left mounting frame 21 and the right mounting frame 22 to realize the synchronous rotation of the two and the rotation of the rotating disk 12. On the other hand, the impurities and turning debris dropped into the processing cylinder 11 are discharged through the impurity discharge pipe 17 through the circumferential rotation of the connecting scrapers 26.

[0041] A plurality of fixed tubes 27 are fixedly connected to the connecting scraper 26, and the fixed tube 27 is connected to a movable rod 28 that slides therewith through a spring 29, and the movable rod 28 is fixedly connected to the abutment seat 23. Under the compressive elastic action of the movable rod 28 and the spring 29, the abutment seat 23 centeringly clamps the copper rod and cleans the dust and impurities on the surface of the copper rod.

[0042] An outer gear ring 210 is fixedly connected to the left mounting frame 21, and a rotating ring extending to the outside of the processing cylinder 11 is fixedly connected to the left mounting frame 21. The outer gear ring 210 is installed on the rotating ring. A motor 15 is bolted to the outer wall of the processing cylinder 11, and a gear 16 meshing with the outer gear ring 210 is fixedly connected to the output shaft of the motor 15. The motor 15 drives the left mounting frame 21 to rotate through the meshing gear 16 and the outer gear ring 210. The left mounting frame 21, with the cooperation of multiple connecting scrapers 26, carries the right mounting frame 22 to rotate, thereby driving the multiple abutment seats 23 and the Z-shaped plates 24 to perform stable circumferential rotation.

[0043] An L-shaped turning tool 211 is bolted on the abutment seat 23, and one end of the copper rod is inserted into the processing tube 11. The connecting scraper 26 is driven to rotate through the mounting frame. The connecting scraper 26 drives the abutment seat 23 to carry the L-shaped turning tool 211 to rotate circumferentially through the fixed tube 27 and the movable rod 28, so as to perform ring cutting on the copper rod inserted into the processing tube 11, so that one end of the copper rod after ring cutting can be easily passed through the drawing die 14, eliminating the additional end pretreatment step, so as to improve the convenience of drawing processing;

[0044] A guide abutment block 212 is fixedly connected between the L-shaped turning tool 211 and the cleaning brush 25 on the abutment seat 23. When the copper rod ring cutting section moves to the position of the guide abutment block 212, the guide abutment block 212 guides multiple abutment seats 23 to carry the L-shaped turning tools 211 away from the copper rod at the same time, automatically stopping the turning process of the copper rod, and compressing the elastic force generated by the corresponding spring 29 through the movable rod 28 to maintain the centering clamping of the copper rod, while carrying the cleaning brush 25 to autonomously contact the copper rod to clean the particulate impurities on the surface of the copper rod to prevent the particulate impurities from affecting the surface finish after drawing. The bottom of the processing cylinder 11 is fixedly connected to a debris removal pipe 17.

[0045] A through groove is formed on the rotating disk 12 for the corresponding Z-shaped plate 24 to pass through, so that one end of the Z-shaped plate 24 passes through the rotating disk 12 and extends into the oil coating chamber. A sealing groove connected to the corresponding through groove is formed in the rotating disk 12. A sealing block slidably connected to the sealing groove is fixedly connected to the Z-shaped plate 24. The through groove is sealed by the provided sealing groove and the sealing block to prevent the lubricating oil in the oil coating chamber from entering the impurity removal chamber through the through groove.

[0046] The drawing assembly 4 includes two sets of mounting plates 41 fixedly connected to the top of the base 1, and two sets of movable platforms 42 for reverse movement are arranged between the mounting plates 41. Clamping hydraulic cylinders 43 are symmetrically bolted on both sides of the top of the movable platform 42, and the ends of the piston rods of the clamping hydraulic cylinders 43 are fixedly connected to clamping blocks 44. After the oiled copper rod passes through the processing cylinder 11 and the drawing die 14, the two sets of clamping hydraulic cylinders 43 on one side of the movable platform 42 drive the corresponding clamping blocks 44 to clamp the copper rod.

[0047] The two groups of movable tables 42 are driven to move relative to each other, and the copper rod is pulled together with the drawing die 14 for drawing processing, until the distance between the two groups of movable tables 42 is minimized, and the two groups of movable tables move away from each other, and the clamping hydraulic cylinder 43 in the movement direction close to the drawing die 14 drives the clamping block 44 to reset, and the copper rod is not clamped, and the clamping hydraulic cylinder 43 pushes the clamping block 44 to clamp the copper rod in the movement direction away from the drawing die 14 through another movable table 42, and the copper rod is continuously drawn without stopping.

[0048] A bidirectional screw rod 45 threadedly connected to the two groups of movable platforms 42 is rotatably connected between the mounting plates 41, and a sliding rod slidably connected to the movable platforms 42 is symmetrically fixedly connected between the mounting plates 41 for stable sliding of the two groups of movable platforms 42. Bolts are installed on the mounting plates 41 for driving the corresponding bidirectional screw rod 45 to rotate. The bidirectional screw rod 45 is driven to rotate by the motor 46, and the bidirectional screw rod 45 drives the two groups of movable platforms 42 to move relative to or apart.

[0049] Example 2: Please refer to Figure 4 and Figure 8 As shown, in this embodiment, an oil suction chamber 34 connected to the oil suction hose 31 and the oil injection pipe 32 is opened inside the Z-shaped plate 24, and a piston block 35 is slidably connected inside the oil suction chamber 34. A limit plate 36 is fixedly connected between the rotating disk 12 and the end of the oil suction hose 31. The oil suction hose 31 does not interfere with the position change of the Z-shaped plate 24. At the same time, the limit plate 36 can ensure that the oil suction end of the oil suction hose 31 can smoothly enter the lubricating oil to achieve the oil suction operation. The oil suction hose 31 and the oil injection pipe 32 are fixedly installed with a one-way valve.

[0050] The piston block 35 compresses the spring 2 39 to move, and in combination with the one-way valve on the oil suction hose 31, the lubricating oil in the oil suction chamber 34 is sprayed onto the cleaned copper rod surface through the oil spray pipe 32. Under the compression elasticity of the spring 2 39, the piston block 35 is pushed to reset, and in combination with the one-way valve on the oil spray pipe 32, the lubricating oil in the treatment cylinder 11 is extracted through the oil suction hose 31 to replenish the lubricating oil discharged from the oil suction chamber 34. During the repeated reciprocating motion of the piston block 35, the copper rod is continuously and uninterruptedly sprayed with lubricating oil.

[0051] Furthermore, by guiding the contact of the abutment block 212 with the copper rods of different diameters, the distance between the end of the oil injection pipe 32 and the copper rods of different diameters is kept constant, so that the problem of spraying contact cannot be caused by extending the spraying distance due to the copper rods of smaller diameters, and conversely, the problem of excessive increase in splashing area due to spraying on the copper rods of larger diameters will not occur. At the same time, the oil-absorbing sponge 33 can be made to contact the copper rod autonomously, and the excess lubricating oil sprayed on the surface of the copper rod can be effectively absorbed, thereby avoiding waste of lubricating oil and achieving uniform coating, further improving the lubrication effect.

[0052] A push rod 37 that slides with the Z-shaped plate 24 is fixedly connected to the piston block 35, a semicircular guide ring 38 that matches the push rod 37 is fixedly connected to the inner side wall of the treatment cylinder 11, and both side ends of the semicircular guide ring 38 are provided with guiding inclined surfaces, and a spring 2 39 is fixedly connected between the piston block 35 and the oil suction chamber 34;

[0053] During the downward rotation of the Z-shaped plate 24 from the highest position, the pushing rod 37 is guided by the guiding bevel on the upper side of the semicircular guide ring 38, so that the pushing rod 37 carries the piston block 35 to compress the spring 2 39 to move, and the lubricating oil in the oil suction chamber 34 is sprayed to the cleaned copper rod surface through the oil spray pipe 32, and with the cooperation of the semicircular guide ring 38, it is ensured that the position of the piston block 35 in the oil suction chamber 34 remains unchanged during the downward rotation of the Z-shaped plate 24. When the Z-shaped plate 24 rotates to the lowest point, the pushing rod 37 is separated from the semicircular guide ring 38, and the piston block 35 is pushed to reset under the compression elasticity of the spring 2 39, and the lubricating oil in the treatment cylinder 11 is extracted through the oil suction hose 31 to replenish the lubricating oil discharged from the oil suction chamber 34.

[0054] A sliding groove is formed through the Z-shaped plate 24, and a square movable block 310 is slidably connected in the sliding groove. The square structure of the square movable block 310 and the sliding groove adapted thereto enable the square movable block 310 to reciprocate only in the vertical direction of the push rod 37, thereby realizing the squeezing effect of the oil-absorbing sponge 33 in combination with the copper rod. The square movable block 310 is fixedly connected to the oil-absorbing sponge 33 through the push plate 311.

[0055] Guide grooves are symmetrically provided on both sides of the sliding groove. A push pin 312 is fixedly connected to the push rod 37 and is slidably connected to the guide groove. The guide groove is combined with the push pin 312 and the sliding of the push rod 37 and the Z-shaped plate 24 to further improve the stability of the horizontal movement of the push rod 37 and avoid the problem of increasing the friction between the piston block 35 and the oil suction chamber 34 and reducing the service life of the piston block 35 during the movement of the square movable block 310. An oblique guide groove 313 is provided on the square movable block 310 to slide with the push pin 312.

[0056] After the lubricating oil is sprayed onto the surface of the copper rod through the oil spray pipe 32, the excess lubricating oil on the surface of the copper rod is absorbed by the oil-absorbing sponge 33 that is in contact with the copper rod, and the lubricating oil on the surface of the copper rod is further evenly coated with the lubricating oil driven by the circumferential rotation of the Z-shaped plate 24. In addition, during the movement of the piston block 35 and the compression spring 2 39 carried by the push rod 37, the square movable block 310 and the push plate 311 are prompted to move toward the copper rod by sliding the push pin 312 in the oblique guide groove 313, so that the excess lubricating oil absorbed in the oil-absorbing sponge 33 is squeezed out, thereby avoiding the subsequent coating of excessive lubricating oil on the copper rod, which causes a waste of lubricating oil.

[0057] Example 3: Please refer to Figure 1-Figure 8 As shown, the present invention also proposes a method for using a copper rod processing and drawing device based on an autonomous lubrication mechanism, comprising the following steps:

[0058] Step 1: Insert one end of the copper rod into the processing cylinder 11, and the motor 15 drives the left mounting frame 21 to rotate through the meshing gear 16 and the outer gear ring 210. The left mounting frame 21, in cooperation with a plurality of connecting scrapers 26, drives the right mounting frame 22 to rotate, thereby driving a plurality of abutment seats 23 and the Z-shaped plate 24 to perform stable circumferential rotation, and the end of the copper rod is automatically processed by the L-shaped turning tool 211 installed on the abutment seat 23, so that the end of the copper rod can easily pass through the drawing die 14;

[0059] Step 2: When the copper rod cutting section moves to the position of the guide abutment block 212, the guide abutment block 212 guides the plurality of abutment seats 23 to carry the L-shaped turning cutters 211 away from the copper rod at the same time, automatically stopping the turning process of the copper rod, and compressing the elastic force generated by the corresponding spring 1 29 through the movable rod 28 to maintain the centering clamping of the copper rod, and the cleaning brush 25 contacts the copper rod to clean the dust and impurities on the surface of the copper rod, and then the impurities dropped into the processing cylinder 11 are discharged through the impurity discharge pipe 17 by the rotation of the connecting scraper 26;

[0060] Step 3: Add lubricating oil to one side of the oiling assembly 3 in the treatment cylinder 11. When the Z-shaped plate 24 rotates downward from the highest position, the push rod 37 is guided by the guiding inclined surface on the upper side of the semicircular guide ring 38, so that the push rod 37 carries the piston block 35 to compress the second spring 39 to move, and the lubricating oil in the oil suction chamber 34 is sprayed to the surface of the cleaned copper rod through the oil spray pipe 32 in combination with the one-way valve, and with the cooperation of the semicircular guide ring 38, the position of the piston block 35 in the oil suction chamber 34 is ensured to remain unchanged;

[0061] When the Z-shaped plate 24 rotates to the lowest point, the push rod 37 separates from the semicircular guide ring 38, and under the compression elasticity of the spring 2 39, the piston block 35 is pushed to return to the original position, and the lubricating oil in the treatment cylinder 11 is extracted through the oil suction hose 31 in combination with the one-way valve to replenish the lubricating oil discharged from the oil suction chamber 34, and the above-mentioned circumferential rotation process of the Z-shaped plate 24 is repeated to continuously spray the lubricating oil on the copper rod;

[0062] Step 4: After the lubricating oil is sprayed onto the surface of the copper rod through the oil spray pipe 32, the excess lubricating oil on the surface of the copper rod is absorbed by the oil-absorbing sponge 33 that is in contact with the copper rod, and the lubricating oil on the surface of the copper rod is further evenly coated under the circumferential rotation of the Z-shaped plate 24. In addition, during the movement of the piston block 35 and the compression spring 2 39, the push rod 37 carries the piston block 35, and the push pin 312 cooperates with the oblique guide groove 313 to synchronously push the push plate 311 toward the copper rod, so as to squeeze out the excess lubricating oil absorbed in the oil-absorbing sponge 33, thereby avoiding the subsequent coating of excess lubricating oil on the copper rod, resulting in a waste of lubricating oil.

[0063] Step 5: After the oiled copper rod passes through the processing tube 11 and the drawing die 14, the two groups of clamping hydraulic cylinders 43 on the movable table 42 on one side drive the corresponding clamping blocks 44 to clamp the copper rod, and then the two-way screw rod 45 is driven to rotate by the motor 2 46, and the two-way screw rod 45 drives the two groups of movable tables 42 to move relative to each other, pulling the copper rod to combine with the drawing die 14 for drawing processing, and then driving the two-way screw rod 45 to rotate in the opposite direction, and the two groups of movable tables 42 move away from each other, and the clamping hydraulic cylinder 43 in the direction of movement away from the drawing die 14 pushes the clamping block 44 to clamp the copper rod, and the clamping hydraulic cylinder 43 in the direction of movement close to the drawing die 14 drives the clamping block 44 to reset, without clamping the copper rod, and then the copper rod is continuously and non-stop drawn.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
