Description

Technical Field

[0001] The present invention relates to the technical field of cold rolling equipment, and specifically to a high-precision twenty-high cold rolling mill. Background Art

[0002] A twenty-high cold rolling mill is a high-precision device for cold rolling metal sheets. It has twenty rolls, including work rolls, intermediate rolls, and backup rolls, etc. Through a reasonable roll configuration and precise rolling process, it can achieve high-precision rolling of sheets. This device can roll extremely thin metal sheets, such as stainless steel, copper, aluminum, etc. The produced sheets have small thickness tolerances, high surface quality, and good flatness. It is widely used in industries with extremely high requirements for sheet accuracy and quality, such as electronics, automotive, aerospace, etc., and is an important and indispensable device in the modern metal processing field.

[0003] However, in some existing technologies, in order to improve the rolling smoothness and cooling and heat dissipation, lubricating oil is often sprayed on the surface of the sheet. However, the current spraying system has obvious defects. It is difficult for the lubricating oil to be evenly covered on the sheet, affecting the consistency of the rolling effect. At the same time, the lubricating oil is easy to drip during the spraying process, not only causing waste but also polluting the working environment. In addition, the dust on the surface of the sheet before rolling is not properly treated, which not only hinders the uniform formation of the lubricating oil film, but also greatly reduces the lubrication and cooling performance of the lubricating oil mixed with dust.

[0004] In response to this, in order to improve the method of adding lubricating oil to the surface of the sheet and cleaning the dust on the surface of the sheet to avoid the influence of dust on the effect of the lubricating oil, the present application proposes a high-precision twenty-high cold rolling mill. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a high-precision twenty-high cold rolling mill, which solves the problems of the method of adding lubricating oil to the surface of the sheet and cleaning the dust on the surface of the sheet.

[0007] Preferably, the transmission component includes a first transfer rod fixedly connected to the left part of the opposite ends of the front and rear displacement blocks and a second transfer rod fixedly connected to the front and rear ends of the oil cavity box. Connecting rods are rotatably connected to the outer walls of the second transfer rods. The other ends of the connecting rods are rotatably connected to the outer walls of the first transfer rods.

The other ends of the springs are fixedly connected to the inner wall of the storage box. The opposite ends of the lifting plate are fixedly connected to the opposite ends of the fixing plate. Here, the springs are located between the fixing plate and the storage box and are in a compressed state, so they have elastic potential energy.

[0009] Preferably, a card slot is opened in the middle of the inner wall of the lifting plate. Wedge blocks are provided on the inner wall of the card slot and are located on the opposite side of the storage box. Here, the outer wall shape of the wedge block fits the inner wall shape of the card slot to limit the random sliding of the lifting plate.

[0010] Preferably, the dust cleaning component includes a transmission rod rotatably connected to the rear end of the inner wall of the semi-enclosure frame and pressing plates fixedly connected to the left and right sides of the inner walls of the opposite ends of the semi-enclosure frame. Sponge rings are fixedly connected to the outer walls of the transmission rods, and the outer walls of the sponge rings are in contact with the inner walls of the opening of the semi-enclosure frame. Here, the sponge ring has high strength elasticity. The upper part of the inner wall of the pressing plate is a through groove for the flow of dust, and the part of the pressing plate in contact with the sponge ring is arc-shaped.

[0011] Preferably, motors are fixedly connected to the front ends of the semi-enclosure frames.

[0013] Preferably, the pipe connection component includes docking nozzles fixedly connected to the left ends of the enclosing boxes and bending pipes fixedly connected to the front and rear parts on the left side of the outer wall of the semi-enclosure frame. A number of through pipes are fixedly connected to the inner side of the outer wall of the bending pipe, and the other ends of the through pipes are fixedly connected to the left side of the outer wall of the semi-enclosure frame. Here, the distance between the two ends of the semi-enclosure frame is relatively long, so through pipes need to be provided at multiple places on its outer wall to maintain the distribution of negative pressure air flow.

[0014] Preferably, bellows are fixedly connected to the other ends of the docking nozzles, vertical pipes are fixedly connected to the other ends of the bellows, and the other ends of the vertical pipes are respectively fixedly connected to the front and rear parts on the opposite sides of the outer wall of the bending pipe.

Here, the distance between the front and rear ends of the inner wall of the through groove box is the same as that between the front and rear ends of the inner wall.

[0016] The present invention provides a high-precision twenty-high cold rolling mill. It has the following beneficial effects:

[0017] 1. The present invention realizes rolling coating of lubricating oil on both sides of the plate through the cooperation of the electric push rod, the oil chamber box, the oil storage box, the hose, the receiving rod and the oil roller, so that the lubricating oil can be evenly applied to the surface of the plate to form an oil film, and then through the cooperation of the transfer rod 2, the connecting rod and the transfer rod 1, when the oil chamber box is pushed by the electric push rod, the displacement block will slide in the slide frame and displace the storage box through the connecting rod. At the same time, after the wedge block is pulled out in advance and the limit on the lifting plate is released, the retaining plate is displaced with the spring elastic force, so that the sponge ring in the semi-enclosed frame will eventually fit with the surface of the plate, and then the sponge ring will wipe the dust on the surface of the plate when the storage box is displaced, and the subsequent plates will contact with the sponge ring before continuing to enter the rolling mill body, and the dust on the surface of the plate will be cleaned through friction, so as to avoid the subsequent lubricating oil from contacting with the dust, thereby affecting the performance of the lubricating oil.

[0018] 2. The present invention realizes that the sponge ring with dust is squeezed by the pressing plate after entering the semi-enclosure through the cooperation of the motor, the transmission rod, the sponge ring and the pressing plate, and then the dust on the surface is bounced off by the cooperation of the elasticity of the sponge ring itself and the local squeezing formed by the pressing plates on both sides. Then, the dust scattered in the semi-enclosure is collected through the cooperation of the bending tube, the through tube, the vertical tube, the bellows, the docking nozzle, the enclosure box, the pull-out box, the bag net and the exhaust fan, so as to clean the dust on the surface of the sponge ring and avoid excessive dust adhesion, which affects the cleaning effect of the sponge ring on the plate.

DETAILED DESCRIPTION

[0030] 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.

[0031] Embodiment 1:

[0032] Please see attached Figure 1 - Attachment Figure 3 , Attachment Figure 5, an embodiment of the present invention provides a high-precision twenty-high cold rolling mill, including a frame 1. Inside the inner wall of the frame 1, there is a rolling mill main body 2. At the middle parts of the left and right ends of the frame 1, an inlet groove 11 and an outlet groove 14 are respectively opened. At the bottoms of the front and rear sides of the left end of the frame 1, extension plates 3 are fixedly connected. At the top ends of the extension plates 3, a through groove box 4 is fixedly connected. At the upper and lower sides of the left and right ends of the frame 1, electric push rods 6 are installed. The driving ends of the electric push rods 6 are fixedly connected with oil cavity boxes 7. At the front and rear ends of the inner wall of the oil cavity box 7, receiving rods 19 are rotatably connected. On the outer walls of the receiving rods 19, oil rollers 17 are fixedly connected. The two sides of the outer wall of the oil roller 17 are respectively in contact with the inner wall of the opening of the oil cavity box 7. At the upper and lower sides of the rear end of the frame 1, oil storage boxes 9 are fixedly connected. At the left and right ends of the oil storage box 9, hoses 10 are installed. The other ends of the hoses 10 are respectively fixedly connected to the rear parts of the opposite ends of the upper and lower oil cavity boxes 7. At the front and rear sides of the left end of the frame 1 located at the inlet groove 11, chute frames 5 are fixedly connected. At the upper and lower sides of the inner wall of the chute frame 5, displacement blocks 8 are slidably connected. The displacement blocks 8 and the left and right ends of the oil cavity box 7 are connected through a transmission assembly. At the right sides of the opposite ends of the front and rear displacement blocks 8, connecting rods 18 are fixedly connected. At the opposite ends of the front and rear connecting rods 18, storage boxes 13 are fixedly connected. Inside the storage boxes 13, fixing plates 20 are connected through a telescopic assembly. At the opposite ends of the fixing plates 20, semi-enclosing frames 31 are fixedly connected. Inside the semi-enclosing frames 31, dust cleaning assemblies are installed. At the front and rear sides of the opposite ends of the storage boxes 13, enclosing boxes 26 are fixedly connected. Inside the enclosing boxes 26, collecting assemblies are arranged. The enclosing boxes 26 are connected to the semi-enclosing frames 31 through a connecting pipe assembly;

[0033] For further explanation, first, at the beginning of the operation, one end of the coiled sheet needs to be pulled out from the transmission equipment, and then the sheet is made to pass through the inner wall of the through groove box 4 in sequence until it reaches the inlet groove 11. The through groove box 4 will limit the movement range of the sheet during translation to prevent it from detaching. At this stage, the operator needs to precisely adjust the driving stroke of the electric push rod 6 with the help of the control platform according to the known thickness of the sheet. The purpose of the adjustment is to ensure that when the electric push rods 6 located on the upper and lower sides of the inlet groove 11 push the oil cavity box 7, their strokes can be kept consistent. In this way, the outer wall of the oil roller 17 can be closely attached to one side of the sheet. Similarly, for the electric push rods 6 located on the upper and lower sides of the outlet groove 14, their adjustment needs to be made according to the thickness condition of the sheet after cold rolling. It is necessary to make the strokes of these two sides of the electric push rods 6 consistent when pushing the oil cavity box 7, and to ensure that the distance between the oil rollers 17 at this place is precisely matched with the thickness of the sheet after cold rolling. In this way, when the sheet extends out from the outlet groove 14, both sides of it can be in contact with the outer walls of the oil rollers 17 at this place;

[0034] After the preparatory work is completed, the oil pump in the oil storage box 9 starts to operate, pumping out the lubricating oil stored inside. One end of the hose 10 passes through the oil storage box 9 and is connected to the oil pump, and a one-way valve is installed between the other end of the hose 10 and the oil cavity box 7. The lubricating oil is transported to the connected oil cavity box 7 through the hose 10. As the sheet continuously enters the rolling mill main body 2 from the inlet groove 11, both sides of the sheet will rub against the oil rollers 17 on both sides near the inlet groove 11. This friction will cause the oil rollers 17 to rotate in the oil cavity box 7. During the rotation of the oil rollers 17, the lubricating oil adhering to their outer walls in the oil cavity box 7 will be evenly rolled onto the surface of the sheet, thus forming a complete oil film on the surface of the sheet. The formation of this oil film is of great significance. It can significantly reduce the friction coefficient between the sheet and the rolling rolls. On the one hand, it makes the rolling process smoother and effectively avoids the occurrence of adverse phenomena such as jamming. On the other hand, it reduces the rolling force and energy consumption, thereby extending the service life of the equipment;

[0035] When the sheet enters the rolling mill main body 2 and is rolled, it will extend from the outlet groove 14. At this time, the adjusted oil rollers 17 on both sides will play a role again. When the sheet passes between these two oil rollers 17, it will continue to rub against the oil rollers 17, causing the oil rollers 17 to roll the lubricating oil adhering to their outer walls onto the surface of the sheet again. In this way, an oil film is formed on the surface of the sheet again. This oil film is like a strong protective layer, separating the sheet from air and moisture, greatly reducing the risk of the sheet oxidizing and rusting, and effectively extending the storage period and service life of the sheet;

[0036] In addition, this equipment is provided with an external control platform, adopting PLC linkage control technology, and is electrically connected to multiple electric drive devices in the equipment to achieve the control or debugging of the electric drive devices. Since it is an existing technology, it will not be elaborated in this embodiment. When the sheet is in a wound state, it is sleeved on the roller shaft in the transmission device. After starting the drive device to make the roller shaft rotate, one end of the sheet will continuously enter the rolling mill main body 2. After the sheet is rolled, the staff will place one end of it on the roller shaft in the other transmission device again to wind it up again.

[0037] Embodiment 2:

[0038] Please refer to the appendix Figure 4 、appendix Figure 6 and appendix Figure 10, on the basis of the first embodiment, further, the transmission assembly includes a first transfer rod 15 fixedly connected to the left part of the opposite ends of the displacement blocks 8 on the front and rear sides, and a second transfer rod 16 fixedly connected to the front and rear ends of the oil chamber box 7. A connecting rod 12 is rotatably connected to the outer wall of each second transfer rod 16, and the inner wall of the other end of the connecting rod 12 is rotatably connected to the outer wall of the first transfer rod 15. The telescopic assembly includes a lifting plate 28 slidably connected to the inner walls of the middle parts of the opposite ends of the storage box 13, and a spring 37 fixedly connected to the left and right sides of the opposite ends of the fixing plate 20. The other ends of the springs 37 are fixedly connected to the inner wall of the storage box 13. The opposite ends of the lifting plates 28 are fixedly connected to the opposite ends of the fixing plate 20. A clamping groove 38 is formed in the middle of the inner wall of each lifting plate 28, and a wedge block 29 is arranged on the inner wall of each clamping groove 38 and is located on the opposite sides of the storage box 13. The dust cleaning assembly includes a transmission rod 33 rotatably connected to the rear ends of the inner walls of the semi-enclosure 31, and a pressing plate 34 fixedly connected to the left and right sides of the inner walls of the opposite ends of the semi-enclosure 31. A sponge ring 32 is fixedly connected to the outer wall of each transmission rod 33, and the outer wall of each sponge ring 32 is attached to the inner wall of the opening of the semi-enclosure 31;

[0039] Further explanation, before the lubricating oil is roller-coated, for the two oil chamber boxes 7 located on the side of the inlet groove 11, before being pushed by the electric push rod 6, a special preparation operation needs to be carried out. First, pull out the wedge block 29 on the inner wall of the clamping groove 38 on the lifting plate 28. When the wedge block 29 is pulled out, the lifting plate 28 loses its limit. At this time, the springs 37 on both sides in the storage box 13 in a compressed state will quickly pop out from the storage box 13. The pop-out of the springs 37 will drive the fixing plate 20 and the semi-enclosure 31 connected to one end of the fixing plate 20 to move towards one side of the plate until the sponge rings 32 on both sides contact the surface of the plate, forming a clamping and fitting state. During the movement of the semi-enclosure 31, the corrugated pipe 24 will be tractionally stretched through the bent pipe 21 and the vertical pipe 23, increasing its length to meet the subsequent working requirements;

[0040] Subsequently, under the coordinated connection and cooperation of the second transfer rod 16, the connecting rod 12, and the first transfer rod 15, while the oil chamber box 7 is being pushed by the driving end of the electric push rod 6, the displacement block 8 will be indirectly pushed by the thrust of the oil chamber box 7 to slide in the chute of the chute frame 5 in a direction away from the frame 1. Moreover, the two displacement blocks 8 at the same horizontal height will drive the storage box 13 to move together under the connection of the connecting rod 18. During this process, the sponge rings 32 clamping the two sides of the plate will wipe the dust on the surface of the plate. Moreover, during the continuous feeding of the plate into the rolling mill main body 2, the sponge rings 32 will continuously wipe the dust on the surface of the plate. This operation can prevent dust from hindering the formation of the oil film during the subsequent lubricating oil roller-coating process. At the same time, it can also prevent the mixture of dust and lubricating oil from affecting the performance of the lubricating oil, thereby having an adverse impact on the subsequent rolling effect;

[0041] In addition, when the spring 37 is not compressed, its length can extend to the middle position of the inner wall of the inlet groove 11. The elastic force of the spring 37 is sufficient to enable it to return to its original position when not subjected to a compressive force. Handle frames are provided at the opposite ends of the lifting plate 28, so that when it is to be stored later, the staff can hook the handle frames with their fingers to slide it out from the inner wall of the storage box 13, and then reinsert the wedge block 29 into the card slot 38 to limit its position.

[0042] Embodiment Three:

[0043] Please refer to the appendix Figure 7 - appendix Figure 9 , further based on Embodiment Two, motors 30 are fixedly connected to the front ends of the semi-enclosure frames 31. The driving ends of the motors 30 penetrate through the inner walls of the semi-enclosure frames 31 and are fixedly connected to the front ends of the transmission rods 33. The collection assembly includes pull-out boxes 35 provided on the inner walls of the opposite ends of the front and rear enclosing boxes 26. Cloth bag nets 36 are fixedly connected to the inner walls of the left ends of the pull-out boxes 35. Exhaust fans 27 are fixedly connected to the tops of the enclosing boxes 26. The pipe connection assembly includes docking nozzles 25 fixedly connected to the left ends of the enclosing boxes 26 and bending pipes 21 fixedly connected to the front and rear parts on the left outer side of the semi-enclosure frames 31. A plurality of through pipes 22 are fixedly connected to the inward side of the outer walls of the bending pipes 21. The other ends of the through pipes 22 are fixedly connected to the left outer side of the semi-enclosure frames 31. The other ends of the docking nozzles 25 are fixedly connected to corrugated pipes 24. The other ends of the corrugated pipes 24 are fixedly connected to vertical pipes 23. The other ends of the vertical pipes 23 are respectively fixedly connected to the front and rear parts on the opposite sides of the outer walls of the bending pipes 21;

[0044] For further explanation, during the process of the sponge ring 32 wiping the dust on the plate, the operator needs to control the control platform to start the motor 30 and the exhaust fan 27 respectively. Driven by the motor 30, the transmission rod 33 will drive the sponge ring 32 to rotate. When the side of the sponge ring 32 with dust on its surface rotates into the semi-enclosure 31, it will come into contact with the pressing plate 34 in sequence. The pressing plate 34 will squeeze the sponge ring 32. When the squeezed part moves between the two pressing plates 34, due to the good elastic characteristics of the material of the sponge ring 32 itself, this part will quickly rebound. At the same time, under the continuous squeezing action of the two pressing plates 34 on the rest part, the area of the part not being squeezed will gradually decrease. According to the pressure formula P = F / S, when the force is the same, the smaller the force-bearing area, the greater the pressure. Therefore, in this case, the rebound effect of the sponge ring 32 at this place will be significantly increased. In the state of rebound, the sponge ring 32 can strongly bounce off the dust on its surface, making the dust disperse in the semi-enclosure 31. Then, the exhaust fan 27 starts to operate, creating a negative pressure inside the docking nozzle 25 through the holes in the extraction box 35 and the top of the enclosure box 26. Then, through the coordinated cooperation of the docking nozzle 25, the corrugated pipe 24, the vertical pipe 23, the bent pipe 21 and several through pipes 22, the negative pressure air flow can be extended. This negative pressure air flow can suck the dust in the semi-enclosure 31 and introduce it into the cloth bag net 36 for collection, waiting for subsequent cleaning. Through the above series of coordinated operation methods, it is possible to clean the dust on the surface of the sponge ring 32 while the sponge ring 32 is cleaning the dust on the plate, avoiding the influence on the cleaning effect of the plate after too much dust adheres, thus providing good condition guarantee for the subsequent lubricating oil rolling and rolling processes;

[0045] Supplementary explanation: The material of the sponge ring 32 itself uses polyurethane as the raw material. During the production process, through a special foaming process, it forms a sponge material with a specific pore structure and elastic properties, having excellent elastic recovery ability and being able to quickly return to its original shape.
