Description

Technical Field

[0001] The invention relates to the technical field of rolling mills, in particular to a forming rolling mill for producing sheet metal thin plates. Background Art

[0002] Rolling mill is a kind of mechanical equipment used for metal processing, which is particularly important in the steel industry. Rolling mill is used to plastically deform metal materials such as steel, aluminum, copper, etc. through one or more pairs of rotating rollers, thereby changing their shape, size and properties. Its rollers are in direct contact with the metal material, exerting pressure and deforming it.

[0003] Roller cooling of rolling mills is crucial, especially during the cold rolling process. Although the temperature is relatively low, the rollers heat up rapidly under high speed and high pressure. Effective cooling can not only extend the service life of the rollers, but also ensure the stability of the rolling process and product quality. The existing roller cooling method of rolling mills is generally water cooling, in which cooling water is sprayed on the surface of the rollers through nozzles to dissipate the heat of the rollers. This water cooling method has the following problems during use.

[0004] Cooling water adheres to the surface of the rolls, other parts of the rolling mill, and the surface of the metal plate. The large amount of water retention will cause the equipment and metal plates to rust; the presence of a large amount of water will form sewage, causing pollution to the production environment. To this end, we propose a forming rolling mill for sheet metal thin plate production. Summary of the invention

[0021] 1. In the present invention, when the metal plate passes through two working rollers, after the high-speed moist airflow flows toward the metal plate, the high-speed moist airflow discharged downward from both sides of the upper intermediate roller is sprayed toward the upper surface of the metal plate, and the high-speed moist airflow discharged upward from both sides of the lower intermediate roller is sprayed toward the lower surface of the metal plate. During the flow of the airflow, the two upper and lower intermediate rollers and the two working rollers are cooled, and the moist water mist in the airflow evaporates after being heated. The intermediate rollers and the working rollers are cooled by the cooling method of airflow and water mist evaporation. Not only is the cooling efficiency high, but it can also avoid a large amount of moisture remaining on the device and the metal plate, and the problem of sewage being difficult to clean will not occur, and the problem of easy rust of the equipment and the metal plate caused by a large amount of moisture remaining on the surface of the equipment and the metal plate is avoided.

[0022] 2. In the present invention, during the moist airflow cooling process, since a spiral groove is provided on the outer side of the intermediate roller and a plurality of air outlet holes are provided inside the intermediate roller along the spiral groove, during the rotation of the intermediate roller, the moist airflow discharged from the spiral groove and the air outlet holes will be more evenly distributed in the gap between the guide plate and the surface of the intermediate roller, and the evenly distributed moist airflow will enter the gap between the guide plate and the working roller to evenly dissipate heat for the working roller.

[0023] 3.

When the sticky impurities contact the intermediate roll as the working roll rotates, since the outlet end of the air outlet is located on the inner wall of the spiral groove, the sticky impurities will not contact the outlet end of the air outlet, thereby preventing the outlet end of the air outlet from being blocked and preventing the exhaust of the air outlet from being affected.

[0024] 4. In the present invention, when the metal plate passes through the two working rollers, a high-speed moist airflow is sprayed toward the upper and lower surfaces of the metal plate to blow away dust and solid impurities on the upper and lower surfaces of the metal plate, thereby preventing the dust and solid impurities from entering between the two working rollers and being rolled, and preventing the working rollers and the metal plate from being scratched. By using moist airflow to blow away dust and solid impurities, dust problems can also be prevented, and pollution caused by a large amount of dust in the working environment can be avoided.

DETAILED DESCRIPTION

[0038] 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.

[0039] Example

[0040] See also Figure 1 - Fig.10As shown, a forming rolling mill for sheet metal thin plate production includes a machine base 1, two supporting rollers 2, two intermediate rollers 3 and two working rollers 4 movably arranged inside the machine base 1, the two intermediate rollers 3 are located between the two supporting rollers 2, and the two working rollers 4 are located between the two intermediate rollers 3. Four guide components 5 are arranged inside the machine base 1, one guide component 5 is arranged on both sides of the upper supporting roller 2, intermediate roller 3 and working roller 4, and one guide component 5 is arranged on both sides of the lower supporting roller 2, intermediate roller 3 and working roller 4. An air blowing device 6 is arranged on one side of the machine base 1; the intermediate roller 3 of the rolling mill is respectively in contact with the adjacent supporting roller 2 and working roller 4. The metal plate 21 is subjected to force and plastic deformation when passing through the two working rollers 4.

[0041] The air blowing device 6 is used to introduce high-speed moist air into the air injection holes 8 in the two intermediate rollers 3. The sides of the two intermediate rollers 3 are provided with spiral grooves 7, the interiors of the two intermediate rollers 3 are provided with air injection holes 8, and the interiors of each intermediate roller 3 are provided with a plurality of air outlet holes 25 connecting the air injection holes 8 and the spiral grooves 7; during the operation of the rolling mill, the high-speed moist air introduced into the air injection holes 8 by the air blowing device 6 enters the spiral grooves 7 through the air outlet holes 25.

[0042] The guide assembly 5 includes a flow limiting plate 51, a flow guide plate 52 and a flow guide plate 53. The flow limiting plates 51 are arranged on both sides of the upper support roller 2 and the lower support roller 2. The flow limiting plates 51 and the support roller 2 surface are in contact. The flow guiding plates 52 are arranged on both sides of the upper intermediate roller 3 and the lower intermediate roller 3. There is a gap between the flow guiding plates 52 and the intermediate roller 3 surface. The flow guiding plates 53 are arranged on both sides of the upper working roller 4 and the lower working roller 4. There is a gap between the flow guiding plates 53 and the working roller 4. The flow limiting plate 51 is used to scrape off dirt such as dust and impurities on the surface of the support roller 2, and is also used to block the moist airflow so that the moist airflow is blocked at the intermediate roller 3. The flow guide plate 52 is used to prevent dirt such as dust and impurities from adhering to the surface of the intermediate roller 3 and prevent the moist airflow from spreading outward. The flow guide plate 53 is also used to prevent the moist airflow from spreading outward. The flow guiding plates 52 and the flow guide plates 53 also play a role in guiding the flow of the airflow, so that the high-speed moist airflow flows toward the metal plate 21. After being discharged from the air outlet 25 , the high-speed moist airflow enters the gap between the guide plate 53 and the working roll 4 through the gap between the guide plate 52 and the surface of the intermediate roll 3 , thereby cooling the working roll 4 .

[0043] In order to solve the problem that a large amount of water in the water cooling process of the existing roller mill using water cooling for roller cooling will cause environmental pollution and easily lead to mechanical corrosion and plate corrosion, the roller mill in this design uses humid air flow for roller cooling.

[0044] Specific as Figure 7As shown, the arrow in the figure points to the moving direction of the metal plate 21. When the metal plate 21 passes through the two working rollers 4, after the high-speed humid airflow flows to the metal plate 21, the high-speed humid airflow discharged downward from both sides of the upper intermediate roller 3 is sprayed to the upper surface of the metal plate 21, and the high-speed humid airflow discharged upward from both sides of the lower intermediate roller 3 is sprayed to the lower surface of the metal plate 21. During the flow of the airflow, the upper and lower two intermediate rollers 3 and the two working rollers 4 are cooled, and the humid water mist in the airflow evaporates after being heated. The cooling method of airflow and water mist evaporation is used to cool the intermediate roller 3 and the working roller 4. Not only is the cooling efficiency high, but it can also avoid a large amount of water remaining on the device and the metal plate 21, and there will be no problem of sewage being difficult to clean up, and the problem of the equipment and the metal plate 21 being easily rusted due to a large amount of water remaining on the surface of the equipment and the metal plate 21 is avoided.

[0045] In the process of moist airflow cooling, in order to make the cooling of the working roller 4 more uniform, in this design, a spiral groove 7 is opened on the outer side of the intermediate roller 3, and a plurality of air outlet holes 25 are opened inside the intermediate roller 3 along the spiral groove 7. During the rotation of the intermediate roller 3, the moist airflow discharged from the spiral groove 7 and the air outlet holes 25 will be more evenly distributed in the gap between the guide plate 52 and the surface of the intermediate roller 3. The evenly distributed moist airflow will enter the gap between the guide plate 53 and the working roller 4, and evenly dissipate the heat of the working roller 4.

[0046] During the rolling process of the device, if there are sticky impurities on the surface of the metal plate 21 and they are difficult to be blown away by the airflow, the sticky impurities will adhere to the surface of the working roller 4. When the sticky impurities contact the intermediate roller 3 as the working roller 4 rotates, since the outlet end of the air outlet 25 is located on the inner wall of the spiral groove 7, the sticky impurities will not contact the outlet end of the air outlet 25, thereby preventing the outlet end of the air outlet 25 from being blocked, so that the exhaust of the air outlet 25 will not be affected.

[0047] In order to solve the problem that solid impurities on the surface of the rolls and plates are difficult to clean during the plate rolling process of the existing rolling mill, and solid impurities may cause scratches on the plates and rolls, the rolling mill in this design uses a guide assembly 5 to protect the rolls and uses a high-speed airflow to clean solid impurities on the surface of the metal plate 21.

[0048] When the metal plate 21 passes through the two working rollers 4, a high-speed moist airflow is sprayed toward the upper and lower surfaces of the metal plate 21, blowing away dust and solid impurities above and below the metal plate 21, preventing the dust and solid impurities from entering between the two working rollers 4 and being rolled, and preventing the working rollers 4 and the metal plate 21 from being scratched. Using moist airflow to blow away dust and solid impurities can also prevent dust problems and prevent the air in the working environment from being polluted by a large amount of dust.

[0049] A dustproof strip 10 is fixedly provided on the outer edge of each flow limiting plate 51 .

[0050] The dust strip 10 is provided to scrape off dust and impurities attached to the surface of the support roller 2 during the rotation of the support roller 2, and prevent dust and impurities from entering between the support roller 2 and the middle roller 3 and causing scratches on the support roller 2 and the middle roller 3. The dust strip 10 is in contact with the surface of the support roller 2, and also plays a sealing role between the support roller 2 and the flow limiting plate 51, preventing the airflow from escaping from between the support roller 2 and the flow limiting plate 51.

[0051] Among them, four adjustment components 9 are arranged on the inner side of the machine base 1, and the adjustment components 9 and the guide components 5 correspond one to one. The adjustment components 9 drive the guide components 5 to move. The adjustment components 9 include a positioning seat 91 fixedly installed on the inner side of the machine base 1, an electric push rod 92 fixedly installed above the positioning seat 91, a connecting seat 93 arranged on one side of the positioning seat 91, a connecting shaft 94 fixedly arranged on one side of the connecting seat 93, and four limiting shafts 95 fixedly installed on one side of the connecting seat 93. The connecting shaft 94 is fixedly connected to the output end of the electric push rod 92. Four limiting holes 11 are opened inside the positioning seat 91, and the limiting shafts 95 and the limiting holes 11 correspond one to one. The limiting shafts 95 are passed through the corresponding limiting holes 11, and the limiting plate 51, the guide plate 52 and the guide plate 53 are fixedly arranged on the other side of the connecting seat 93.

[0052] Based on this design, the electric push rod 92 drives the connection seat 93 to move through the connecting shaft 94, thereby driving the flow limiting plate 51, the flow guide plate 52 and the flow guide plate 53 to move. By adjusting the positions of the flow limiting plate 51, the flow guide plate 52 and the flow guide plate 53, not only can the gap between the flow guide plate 52 and the surface of the intermediate roller 3, and the gap between the flow guide plate 53 and the working roller 4 be adjusted to adjust the flow rate of the airflow in each gap, but also it is convenient to perform maintenance and other treatments on the support roller 2, the intermediate roller 3 and the working roller 4. The setting of the limiting shaft 95 and the limiting hole 11 makes the moving trajectory of the flow limiting plate 51, the flow guide plate 52 and the flow guide plate 53 on a straight line, thereby improving the moving accuracy.

[0053] Among them, connecting plates 12 are fixedly arranged on the sides of the flow limiting plate 51, the flow guide plate 52 and the guide plate 53, and a bayonet 13 matching each connecting plate 12 is opened inside the connecting seat 93. The connecting plate 12 is stuck inside the corresponding bayonet 13, and the connecting plate 12 is fixedly connected to the connecting seat 93 by bolts 14.

[0054] Based on this design, the setting of the connecting plate 12 and the beginning of the bayonet 13 make the installation position of the flow limiting plate 51, the flow guide plate 52 and the guide plate 53 on the connecting seat 93 more precise. The connecting plate 12 is connected to the connecting seat 93 by bolts 14, which makes the connection between the flow limiting plate 51, the flow guide plate 52 and the guide plate 53 more stable and also facilitates the disassembly and assembly of the flow limiting plate 51, the flow guide plate 52 and the guide plate 53.

[0055] Among them, the air blowing device 6 includes an atomizer 61 fixedly installed on the upper side of the machine base 1, an air guide component 62, and a three-way pipe 63 fixedly connected to the air outlet end of the air guide component 62. The air outlet end of the atomizer 61 and the air inlet end of the air guide component 62 are connected by a pipeline. The two air outlet ends of the three-way pipe 63 are respectively connected to an intermediate roller 3. The three-way pipe 63 is used to supply air to the air injection hole 8 in the intermediate roller 3.

[0056] Based on the present design, the air guide assembly 62 guides the humidified gas generated by the atomizer 61 into the two intermediate rollers 3 through the three-way pipe 63, so that the humidity and the displacement of the humidified air discharged from the two intermediate rollers 3 are similar.

[0057] Among them, two mounting frames 15 are fixedly installed on the side walls of the machine base 1, and an air connecting pipe 16 is fixedly installed on the end of each mounting frame 15. The upper air connecting pipe 16 is movably and sealedly connected to the upper intermediate roller 3, and the lower air connecting pipe 16 is movably and sealedly connected to the lower intermediate roller 3. The two air outlet ends of the three-way pipe 63 are each connected to an air connecting pipe 16, and the air connecting pipe 16 and the three-way pipe 63 are fixedly connected.

[0058] Based on this design, the installation of the mounting frame 15 facilitates the installation and fixation of the air pipe 16, the air pipe 16 and the intermediate roller 3 are movably sealed and connected, and the air pipe 16 and the three-way pipe 63 are fixedly connected, ensuring that the device has high air tightness.

[0059] Among them, the air guide component 62 includes a tank body 621 fixedly installed above the machine base 1, a tank cover 622 fixedly installed above the tank body 621, a first mesh plate 623 fixedly installed in the middle of the tank body 621, a hydrophobic filter cotton 624 arranged above the first mesh plate 623, a sealing plate 625 arranged above the inside of the tank body 621, and an exhaust fan 626 fixedly installed above the sealing plate 625. An exhaust port 17 is opened above the side of the shell of the tank body 621, a through pipe 18 is fixedly installed in the middle of the sealing plate 625, the air inlet end of the exhaust fan 626 is fixedly connected to the through pipe 18, the air outlet end of the exhaust fan 626 is connected to the exhaust port 17, and the air inlet end of the three-way pipe 63 is connected to the exhaust port 17.

[0060] Based on this design, the tank body 621 and the tank cover 622 are used to store the water mist generated by the atomizer 61, so that there is enough water mist for use when the rolling mill is working. The hydrophobic filter cotton 624 is set to intercept droplets. When the exhaust fan 626 extracts the water mist, it prevents the stored water mist from gathering in large quantities with the airflow, forming droplets and entering the intermediate roller 3 and the working roller 4, and forming attachments on the surfaces of the intermediate roller 3, the working roller 4 and the metal plate 21, causing the intermediate roller 3, the working roller 4 and the metal plate 21 to rust. The first mesh plate 623 is used to carry the hydrophobic filter cotton 624. The sealing plate 625 is used to isolate the bottom water mist to prevent the exhaust fan 626 from rusting in a humid environment. The water mist enters the exhaust fan 626 through the through pipe 18. The droplets further gather after entering the hydrophobic filter cotton 624 and drip into the bottom of the tank body 621.

[0061] A second mesh plate 26 is disposed above the hydrophobic filter cotton 624 , and a pressure ring 19 is disposed above the second mesh plate 26 .

[0062] Based on this design, the pressure ring 19 and the second mesh plate 26 are used to press the hydrophobic filter cotton 624 to prevent the exhaust fan 626 from having excessive suction force and lifting the hydrophobic filter cotton 624.

[0063] Among them, an air pressure valve 20 is fixedly arranged at the lower side of the tank body 621.

[0064] Based on this design, the air pressure valve 20 is a solenoid valve, and a humidity sensor 23 and an air pressure sensor 24 are provided inside the tank body 621. When the air pressure sensor 24 detects that the air pressure inside the tank body 621 is lower than the threshold, the air pressure valve 20 opens, and the outside air enters the inside of the tank body 621 to avoid affecting the operation of the exhaust fan 626. When the humidity sensor 23 detects that the humidity inside the tank body 621 is too high, the atomizer 61 stops working, the air pressure valve 20 opens, and the outside air enters the inside of the tank body 621 to reduce the humidity inside the tank body 621 and prevent the water mist from gathering into droplets.

[0065] A drain valve 22 is fixedly arranged in the middle of the bottom of the tank body 621 .

[0066] Based on this design, the drain valve 22 is used to discharge the moisture accumulated at the bottom of the tank body 621.
