Description

Technical Field

[0001] The invention relates to the field of cable production, in particular to a copper rod wire drawing machine with lubrication effect. Background Art

[0002] In modern industrial production, copper rod wire drawing machines play a vital role. Copper rod wire drawing is to make the thick copper rod through a series of stretching processes to gradually reduce its diameter to meet different production needs.

[0003] Existing copper rod wire drawing machines are usually driven by a motor, which drives the winding wheel to rotate through the rotating shaft, and pulls the copper rod from one end into the wire drawing box for stretching processing. The copper rod is squeezed by the through hole on the wire drawing box, and gradually becomes thinner during the wire drawing process, thereby achieving the wire drawing processing effect.

[0004] At present, there are many types of copper rod wire drawing machines on the market, but there are still some problems in actual use. On the one hand, in the wire drawing process of traditional copper rod wire drawing machines, due to the lack of effective lubrication measures, the friction between the copper rod and the wire drawing die is large, which can easily cause damage to the surface of the copper rod and affect the product quality. At the same time, the large friction will also increase the wear of the equipment and reduce the service life of the equipment. On the other hand, some existing lubrication methods often cannot accurately control the amount of lubricating oil used, which can easily cause waste of lubricating oil or insufficient lubrication. At the same time, some wire drawing machines with lubrication mechanisms also require staff to manually control and start and stop lubrication during the lubrication process. In addition, copper rods of different thicknesses have different requirements for lubricating oil during the wire drawing process, and it is difficult for existing copper rod wire drawing machines to flexibly adjust the amount of lubrication according to the specific situation of the copper rod.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the specification 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.

[0033] Embodiment 1: The embodiment of the present invention provides a copper rod wire drawing machine with lubrication effect, such as Figure 1 ,2 As shown, the machine body 1 includes a box door 2, and the bottom of the box door 2 is hinged to the bottom of the machine body 1, so that the box door 2 can be flipped down along the machine body 1 to open. The machine body 1 is rotatably connected with a rotating shaft 6, and the machine body 1 is fixedly connected with a motor 5, one end of the rotating shaft 6 is connected to the output shaft of the motor 5, and the rotating shaft 6 rotates under the drive of the motor 5. A plurality of traction wheels 14 are fixedly connected to the rotating shaft 6, so that the traction wheels 14 are driven to rotate during the rotation of the rotating shaft 6, thereby achieving the effect of traction of multiple copper rods.

[0034] like Figure 3 , 4 As shown, a quantitative lubrication mechanism 7 is provided on the body 1, and the quantitative lubrication mechanism 7 includes an oil storage cylinder 701, a quantitative cylinder 702, a diverter cylinder 704 and a valve assembly. The oil storage cylinder 701 and the quantitative cylinder 702 are coaxially arranged up and down, and the oil storage cylinder 701 and the quantitative cylinder 702 are connected, wherein the diameter of the quantitative cylinder 702 is smaller than that of the oil storage cylinder 701; the bottom of the oil storage cylinder 701 is fixedly connected to the body 1, so that the top of the body 1 provides support for the oil storage cylinder 701, and the top of the oil storage cylinder 701 is provided with an oil inlet nozzle 713, which is used to introduce lubricating oil into the oil storage cylinder 701 through the oil inlet nozzle 713 for storage.

[0035] like Figure 4 , Figure 5 As shown, the valve assembly includes a hollow rod 101 that penetrates the oil storage cylinder 701, and a partition plate 106 is provided at the bottom of the hollow rod 101. The edge of the partition plate 106 is in close contact with the inner wall of the quantitative cylinder 702, so that the partition plate 106 can move in the quantitative cylinder 702 like a piston. When the partition plate 106 moves downward, the storage space below the partition plate 106 becomes smaller; and when the partition plate 106 moves upward, the storage space below the partition plate 106 becomes larger. According to the length of the copper rod, the required lubricating oil is calculated, and by adjusting the upper and lower positions of the partition plate 106 in the quantitative cylinder 702, the amount of lubricating oil can be flexibly controlled to reduce the waste of lubricating oil.

[0036] like Figure 4As shown, a cover 16 is provided on the top of the oil storage cylinder 701, and a rectangular strip is provided on the outside of the hollow rod 101 along its length direction. The hollow rod 101 can be slidably penetrated in the cover 16. A hole with the same profile as the cross-sectional shape of the hollow rod 101 is provided in the center of the cover 16, so that the hollow rod 101 can only slide relative to the cover 16, and the rectangular strip is used to limit the rotation of the hollow rod 101 relative to the cover 16. The cover 16 is provided with a latch 11 and a first spring 12, and the hollow rod 101 is provided with a plurality of slots 13 arranged along its length direction, and the slots 13 are plugged with the latch 11. When the partition plate 106 is adjusted to a proper position, the latch 11 is inserted into the slot 13 by the elastic force of the first spring 12 to fix the position of the hollow rod 101, thereby keeping the volume of lubricating oil below the partition plate 106 unchanged.

[0037] like Figure 6 As shown, a through hole 105 is provided on the partition plate 106; a core shaft 102 is passed through the hollow rod 101, and the core shaft 102 passes through the bottom of the hollow rod 101, and the core shaft 102 is rotatably connected to the hollow rod 101, and a valve plate 104 is provided at the bottom of the core shaft 102, and the valve plate 104 is in close contact with the partition plate 106, and the through hole 105 is closed or opened by changing the position of the valve plate 104; the quantitative cylinder 702 is provided with a vent pipe 712 to keep the air pressure inside and outside the quantitative cylinder 702 the same, so that the lubricating oil can be discharged. The quantitative cylinder 702 is made of transparent plastic material, which is convenient for the staff to observe the position of the partition plate 106 in the quantitative cylinder 702.

[0038] A knob is provided at the top of the core shaft 102, and a pointer 103 is provided on the knob. The cover body 16 of the metering cylinder 702 is fixedly connected to a dial 161, and an open or closed mark is engraved on the top of the dial 161. At the same time, the pointer 103 is set to correspond to the mark on the top of the dial 161, which makes it convenient for the staff to understand whether the valve assembly is open or closed.

[0039] like Figure 4 , Figure 7As shown, the bottom of the quantitative cylinder 702 is provided with an oil outlet hole, and the oil outlet hole is penetrated by a push rod 705. The diameter of the oil outlet hole is larger than the diameter of the push rod 705, so that the lubricating oil in the quantitative cylinder 702 can flow out along the gap between the oil outlet hole and the push rod 705. The top of the push rod 705 is fixedly connected with a sealing ball 706, so that the push rod 705 drives the sealing ball 706 to move simultaneously during the vertical movement of the push rod 705. The diameter of the sealing ball 706 is larger than the oil outlet hole. When the sealing ball 706 moves to the oil outlet hole position, it can block the oil outlet hole, thereby limiting the lubricating oil from the quantitative cylinder 702. The bottom of the push rod 705 is provided with a second spring 22, and the push rod 705 is fixed to one end of the second spring 22, and the other end of the second spring 22 abuts against the bottom of the quantitative cylinder 702. The push rod 705 is driven downward to reset by the elastic force of the second spring 22, so that the push rod 705 drives the sealing ball 706 set on the top to block the oil outlet hole of the quantitative cylinder 702. The rotating shaft 6 is provided with a single oil outlet mechanism 9, which includes a sleeve 901, which is sleeved on the rotating shaft 6 and can slide axially relative to the rotating shaft 6 to keep the sleeve 901 moving laterally along the outer wall of the rotating shaft 6. The sleeve 901 is fixedly connected with a cam group, which includes a first cam 902, a second cam 903, and a third cam 904. When the sleeve 901 moves laterally, the lateral positions of the first cam 902, the second cam 903, and the third cam 904 are changed at the same time, so that one group of the first cam 902, the second cam 903, and the third cam 904 moves to the bottom of the push rod 705, and the remaining two cams are separated from the bottom of the push rod 705. The contours of the first cam 902, the second cam 903, and the third cam 904 are all different, so that the distances of pushing the push rod 705 upward are different. A conical surface is provided at the bottom of the metering cylinder 702. When the sealing ball 706 moves upward, the gap between the sealing ball 706 and the conical surface increases, and the oil output increases. Conversely, the oil output decreases. When different cams cooperate with the push rod 705, the oil output corresponding to one rotation of the rotating shaft 6 is also different. The outer wall of the sleeve 901 is penetrated by a first bolt 905, and the outer wall of the rotating shaft 6 is provided with a plurality of fixing holes 906. The first bolt 905 is inserted into the fixing hole 906 to fix the sleeve 901 in the axial position of the rotating shaft 6. The first cam 902, the second cam 903, or the third cam 904 cooperates with the bottom of the push rod 705, so that the push rod 705 moves upward, thereby discharging the lubricating oil in the metering cylinder 702 from the oil outlet hole.

[0040] like Figure 4 As shown, the bottom of the metering cylinder 702 is fixedly connected to an oil delivery pipe 703, and the oil delivery pipe 703 is connected to the oil outlet hole. The lubricating oil is discharged from the oil outlet hole and enters the oil delivery pipe 703. Figure 4 , Fig. 9As shown, one end of the oil delivery pipe 703 opposite to the metering cylinder 702 passes through the wire drawing box 3 and is connected to one end of the diverter cylinder 704 , so that the lubricating oil discharged from the metering cylinder 702 is transmitted to the diverter cylinder 704 through the oil delivery pipe 703 .

[0041] like Figure 7 As shown, a diversion hole 707 is opened at the bottom of the diversion cylinder 704. In the present embodiment, four groups of diversion holes 707 are arranged. A soft brush 711 is fixedly connected to the bottom of the diversion cylinder 704 corresponding to the position of the diversion holes 707. Through the design of the soft brush 711, the lubricating oil in the inner wall of the diversion cylinder 704 is evenly smeared on the outer wall of the copper rod moving at the bottom. The inner wall piston of the shunt cylinder 704 is connected with a plug 708, the outer edge of the plug 708 is in close contact with the inner wall of the shunt cylinder 704, and the plug 708 can perform piston movement along the inner wall of the shunt cylinder 704 to control the opening or closing of part of the shunt hole 707. A connecting rod 709 is fixed to the end face of the plug 708 facing away from the oil delivery pipe 703. The connecting rod 709 passes through one end of the shunt cylinder 704, which is convenient for the staff to adjust the lateral position of the connecting rod 709 from the outside of the machine body 1. One end of the connecting rod 709 passes through the machine body 1 and is slidably matched with the machine body 1. The machine body 1 is provided with a second bolt 710 perpendicular to the connecting rod 709 and used to lock the connecting rod 709. The second bolt 710 is used to lock the connecting rod 709, so as to keep the position of the plug 708 relatively fixed.

[0042] like Figure 8 , Fig. 9 As shown, a sponge rubber pad 8 is provided at the bottom of the wire drawing box 3, and the sponge rubber pad 8 is in contact with the copper rod. After the lubricating oil of the brush 711 is applied to the copper rod, part of it will flow onto the sponge rubber pad 8, and the sponge rubber pad 8 will absorb the lubricating oil and apply the lubricating oil to the bottom of the copper rod. The sponge rubber pad 8 cooperates with the brush 711 to complete the application of lubricating oil to the upper and lower surfaces of the copper rod. In addition, the countless tiny holes on the sponge rubber pad 8 can absorb the copper scraps generated during the wire drawing process to keep the surface of the copper rod clean.

[0043] like Fig.11As shown, a recovery box 17 is fixedly connected to the top of the machine body 1, which is used to recycle the lubricating oil absorbed in the sponge rubber pad 8. Specifically, the wire drawing box 3 is opened to take out the sponge rubber pad 8 and place it in the recovery box 17. A leak plate 20 is fixedly connected to the recovery box 17. A gap is set between the leak plate 20 and the bottom of the recovery box 17. The leak plate 20 provides support for the sponge rubber pad 8 when it is placed. There are multiple groups of through grooves on the leak plate 20 for the lubricating oil to leak downward to the bottom of the recovery box 17. A pressure cap 19 with a shape consistent with the inner contour of the recovery box 17 is set in the recovery box 17. The pressure cap 19 can slide against the inner wall of the recovery box 17 to squeeze the lubricating oil in the sponge rubber pad 8 and flow to the bottom of the recovery box 17. The recovery box 17 is also provided with a cylinder 18, which drives the pressure cap 19 to move up and down. The pressure cap 19 can squeeze the sponge rubber pad 8 more quickly and efficiently, and the lubricating oil is squeezed more thoroughly. The lubricating oil collected at the bottom of the recovery box 17 is connected to the oil inlet nozzle 713 of the oil storage cylinder 701 through the reflux pipe 21, and the lubricating oil squeezed out of the sponge rubber pad 8 flows to the oil storage cylinder 701 through the reflux pipe 21 through the bottom of the recovery box 17, thereby achieving the effect of secondary utilization of the lubricating oil. In addition, there are countless gaps in the sponge rubber pad 8, which can absorb the copper chips generated during the copper rod drawing process. The secondary utilized lubricating oil can be kept relatively clean. The sponge rubber pad 8 can be used as a consumable and replaced according to actual conditions.

[0044] Working principle: when copper rod drawing is required, first start the motor 5 to make the motor 5 drive the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the traction wheel 14 to rotate during the rotation, and multiple sets of traction wheels 14 rotate to drive the copper rod forward, so that the copper rod passes through the wire drawing box 3, and multiple sets of wire drawing dies 15 are arranged inside the wire drawing box 3, so that the copper rod passes through the wire drawing die 15 during the traction process, so that the diameter of the copper rod becomes smaller, thereby achieving the purpose of copper rod drawing.

[0045] During the rotation of the traction wheel 14, the first cam 902 arranged on the outer wall of the traction wheel 14 squeezes the top rod 705 arranged on the top, so that the top rod 705 drives the sealing ball 706 to move upward, so that the bottom of the sealing ball 706 is separated from the oil outlet hole at the bottom of the metering cylinder 702, and the lubricating oil in the metering cylinder 702 is discharged from the oil outlet hole. The lubricating oil discharged from the oil outlet hole passes through the oil pipe 703 into the diverter cylinder 704, and flows downward to the brush 711 through the diverter hole 707, so that the brush 711 smears the outer surface of the copper rod passing through, thereby achieving the effect of lubricating the copper rod during the wire drawing process.

[0046] At the same time, taking into account the length of the copper rod for each drawing process, when the copper rod is short, such as when only two groups of copper rods are being drawn, the second bolt 710 is first rotated to release the locking effect of the connecting rod 709, and the connecting rod 709 is moved laterally, so that the connecting rod 709 drives the plug 708 to move laterally, so that the plug 708 moves laterally to block part of the diverter holes 707 of the diverter tube 704, so that the lubricating oil in the diverter tube 704 can only flow downward from the diverter holes 707 near the oil pipe 703, thereby achieving the effect of saving lubricating oil materials and adapting to multiple groups or one group of copper rods for wire drawing.

[0047] In addition, the staff can also rotate the first bolt 905 to release the fixing effect of the first bolt 905 on the sleeve 901, and the sleeve 901 can move axially along the rotating shaft 6, so as to change the axial position of the cam group on the sleeve 901 relative to the rotating shaft 6. For example, when the first cam 902 is displaced to the bottom of the push rod 705, the stroke of the push rod 705 is affected by the contour line of the first cam 902 and is set to the maximum oil output, that is, the contour line of the first cam 902 can bring the push rod 705 to the maximum upward movement distance, and the second cam 903 can drive the push rod 705 to move upward The distance is the second smallest, and the third cam 904 can drive the push rod 705 to move upward The distance is the smallest, and the corresponding oil output is also the smallest, so as to select the corresponding single oil output to adapt to different on-site conditions.

[0048] Considering the different processing time and the length of the copper rod to be drawn, the staff moves the hollow rod 101 upwards, so that the hollow rod 101 drives the partition plate 106 set at the bottom to move vertically along the inner wall of the quantitative cylinder 702, and changes the accommodation space formed by the partition plate 106 and the quantitative cylinder 702, thereby changing the storage amount of the lubricating oil. Then, by rotating the mandrel 102, the mandrel 102 drives the valve plate 104 to rotate, so that the through hole 105 blocked by the valve plate 104 is opened, and the lubricating oil in the oil storage cylinder 701 flows into the bottom of the inner wall of the quantitative cylinder 702 for storage, and the mandrel 102 is rotated again, so that the valve plate 104 closes the through hole 105 of the partition plate 106, thereby achieving the purpose of quantitatively measuring the lubricating oil required for a single copper rod drawing process, so that the staff can choose the appropriate amount of lubricating oil to be used according to the length of the wire drawing process to prevent waste.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
