Description

Technical Field

[0001] The present invention relates to the technical field of roller rolling, and more particularly to a roller rolling device with a surface treatment mechanism. Background Art

[0002] Roll rolling is a metalworking process in which the rolls are a pair or more rotating cylindrical tools used to change the shape, size or structure of metal materials by applying pressure.

[0003] Roll rolling is generally divided into hot rolling and cold rolling. Hot rolling is usually carried out above the recrystallization temperature of the metal material, while cold rolling is carried out at room temperature or near room temperature. When the metal plate requires more precise thickness or width specifications, cold rolling can be used to further reduce the thickness of the material and improve dimensional accuracy.

[0004] Since the material has been hot rolled before, an oxide layer will be formed on the surface during the cooling process after hot rolling. The oxide layer will affect the surface quality and dimensional accuracy of the material during the cold rolling process, and the oxide layer will cause uneven deformation during the cold rolling process, resulting in a decrease in product performance. Therefore, the oxide layer on the surface of the metal plate needs to be completely cleaned off.

[0005] Before cold rolling, the existing oxide layer of the metal plate is usually cleaned with a high-pressure water gun. The high-pressure water gun is generally set on the upper and lower sides of the metal plate to clean the oxide layer on the upper and lower sides of the metal plate, while the oxide layer on the front, back, left and right sides of the metal plate cannot be cleaned. As a result, when the metal plate is cold rolled, the presence of the oxide scale increases the friction coefficient between the contact surface of the roller and the material, resulting in an increase in the rolling force, which may cause additional load on the rolling mill equipment. In addition, the hardness of the oxide scale is usually higher than that of the parent material, which may scratch or accelerate the wear of the roller during the cold rolling process.

[0006] Therefore, it is necessary to design a roller rolling device with high cleaning efficiency and adjustable cleaning to improve the above-mentioned technical problems. Summary of the invention

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0048] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0049] For example, see Figure 1-10The present invention provides the following technical solution: a roller rolling device with a surface treatment mechanism, comprising a first conveyor 1, a rolling mechanism 2 is provided on one side of the first conveyor 1, a second conveyor 4 is provided on one side of the rolling mechanism 2, a positioning mechanism 3 is provided on the upper side of the second conveyor 4, and a cleaning mechanism 5 is provided on the outer side of the second conveyor 4.

[0050] Specifically, the first conveyor 1 and the second conveyor 4 both control the rotation of the rollers through motors to transmit the metal plates. The second conveyor 4 is used to transfer the hot-rolled and cooled metal plates to the cleaning mechanism 5. The cleaning mechanism 5 is used to clean the oxide layer on the surface of the metal plates. The second conveyor 4 then transfers the completely cleaned metal plates to the rolling mechanism 2 for rolling. The rolling mechanism 2 is used to roll metal plates of different thicknesses to the required thickness value. The first conveyor 1 is used to transfer the rolled metal plates to the designated area for packaging. The positioning mechanism 3 is used to position the metal plates during cleaning and before rolling.

[0051] See also Figure 2 The rolling mechanism 2 includes a first support frame 25, and side plates 28 are fixedly connected to the upper sides of the first support frame 25, and a slide groove is provided inside each side plate 28. A first top plate 26 is fixedly connected to the upper side of the side plate 28, and first hydraulic cylinders 21 are fixedly connected to the upper sides of the first top plate 26, and the output end of each first hydraulic cylinder 21 passes through the first hydraulic cylinder 21 and the slider 22 in sequence and is fixedly connected to the slider 22, and the slider 22 is slidably connected to the slide groove, and three upper pressure rollers 27 are connected to the middle bearings of the two sliders 22, and the installation heights of the three upper pressure rollers 27 are arranged from high to low, and three lower pressure rollers 29 are connected to the middle bearings of the two side plates 28, and the installation heights of the three lower pressure rollers 29 are the same.

[0052] Specifically, the extension and retraction of the output end of the first hydraulic cylinder 21 is used to control the movement of the slider 22 up and down, thereby controlling the upper pressure roller 27 to move up and down according to the thickness of the metal plate, and then cooperate with the lower pressure roller 29 to roll the metal plates of different thicknesses. The installation heights of the three upper pressure rollers 27 are set from high to low, so that the metal plate can be rolled three times to different degrees at one time, so that the metal plate does not need to return to batches for three times of different degrees of rolling, saving the rolling time of the metal plate.

[0053] Three first gears 23 are respectively provided on one side of the slider 22 and one side of the side plate 28, wherein one end of the three first gears 23 is fixedly connected to one end of the upper pressure roller 27 and are chain-connected to each other, wherein one end of the other three first gears 23 is fixedly connected to one end of the lower pressure roller 29 and are chain-connected to each other, wherein one side of two first gears 23 is provided with a first motor 24, a support plate is fixedly connected to the lower side of each first motor 24, and the support plate is fixedly connected to the side plate 28, and the output end of the first motor 24 is fixedly connected to the first gear 23.

[0054] Specifically, the rotation of the output end of the first motor 24 is used to control the rotation of the first gear 23, thereby controlling the upper pressing roller 27 and the lower pressing roller 29 to rotate and roll the metal plate.

[0055] The second conveyor 4 conveys the hot-rolled and cooled metal plate to the cleaning mechanism 5, and the cleaning mechanism 5 cleans the oxide layer on the surface of the metal plate. The second conveyor 4 then conveys the completely cleaned metal plate to the rolling mechanism 2 for rolling. Before rolling the metal plate, the positioning mechanism 3 positions the metal plate, and the output end of the first hydraulic cylinder 21 extends to control the upper pressure roller 27 to move downward, thereby adjusting the rolling thickness of the metal plate. The distance from the upper pressure roller 27 with the lowest installation position to the lower pressure roller 29 is the thickness of the metal plate that needs to be rolled. The rotation of the output end of the first motor 24 controls the rotation of the first gear 23, thereby controlling the rotation of the upper pressure roller 27 and the lower pressure roller 29 to roll the metal plate. After the metal plate is rolled, the first conveyor 1 conveys the rolled metal plate to the designated area for packaging.

[0056] By setting the upper pressing rollers 27 at three different heights, the metal plate is rolled three times in sequence to different degrees, so that the metal plate does not need to be returned in batches to be rolled three times to different degrees, saving the rolling time of the metal plate and achieving a high rolling efficiency of the metal plate.

[0057] In the second embodiment, during roller transmission, due to the uneven mass distribution of the roller or the metal plate, the roller may generate unbalanced centrifugal force when rotating, causing vibration, thereby causing the metal plate to shift during transmission. When the metal plate is shifted for cleaning, some areas of the metal plate may be difficult to be directly rinsed by the high-pressure water gun, resulting in incomplete cleaning; when the metal plate is rolled with a shift, it will cause the material thickness to be uneven during rolling, with one side being thick and the other side being thin. In order to correct the shift, it may be necessary to frequently adjust the rolling mill settings, reducing production efficiency. Therefore, the following structure is designed to solve the above technical problems.

[0058] See also Figure 3 and Figure 4 The positioning mechanism 3 includes a fixed plate 31, which is fixedly connected to the lower side of the second conveyor 4. A transmission assembly 32 is provided on the lower side of the fixed plate 31. The transmission assembly 32 includes a second hydraulic cylinder 321, which is fixedly connected to the lower side of the fixed plate 31. The output end of the second hydraulic cylinder 321 is fixedly connected to the first connecting rod 322.

[0059] Specifically, the extension and retraction of the output end of the second hydraulic cylinder 321 is used to control the movement of the first connecting rod 322, thereby controlling the rotation of the second connecting rod 323, and then controlling the rotating clamp 325 to rotate around the rotating clamp 325, driving the positioning plate 33 to approach or move away from the metal plate, and positioning metal plates of different thicknesses.

[0060] A plurality of second connecting rods 323 are hinged on the upper and lower sides of the first connecting rod 322, one end of each second connecting rod 323 is hinged to a third connecting rod 324, one end of each third connecting rod 324 is fixedly connected to an L-shaped rotating column 326, one side of each L-shaped rotating column 326 is fixedly connected to a fixing clamp 327, one side of each fixing clamp 327 is fixedly connected to a positioning plate 33, and a plurality of rotating clamps 325 are fixedly connected to both sides of the second conveyor 4, and the rotating clamps 325 are connected to the bearings of the L-shaped rotating column 326.

[0061] When the metal plate needs to be cleaned or rolled, the output end of the second hydraulic cylinder 321 extends out, and the first connecting rod 322 drives the L-shaped rotating column 326 to rotate with the rotating clamp 325 as the axis point, thereby controlling the positioning plate 33 to approach the metal plate. The two sides of the metal plate are pressed and moved by the positioning plate 33, and then the metal plate is positioned. When the metal plate is positioned, the output end of the second hydraulic cylinder 321 retracts to control the positioning plate 33 to return.

[0062] By extending and retracting the output end of the second hydraulic cylinder 321, the positioning plate 33 is controlled to be close to or away from the metal plate, so as to position the metal plate. This avoids the phenomenon that some areas of the metal plate are difficult to be directly washed by the high-pressure water gun during cleaning or rolling, or the material thickness is uneven during rolling of the metal plate, thereby achieving the effect of uniform cleaning and uniform rolling of the metal plate.

[0063] Embodiment 3: Before cold rolling of the rollers, the existing oxide layer of the metal plate is usually cleaned using a high-pressure water gun. The high-pressure water gun is generally set on the upper and lower sides of the metal plate to clean the oxide layer on the upper and lower sides of the metal plate, while the oxide layer on the front, back, left and right sides of the metal plate cannot be cleaned. As a result, when the metal plate is cold rolled, the presence of the oxide scale increases the friction coefficient between the contact surface of the roller and the material, resulting in an increase in the rolling force, which may cause additional load on the rolling mill equipment. The hardness of the oxide scale is usually higher than that of the base material, and it may scratch or accelerate the wear of the roller during the cold rolling process. Therefore, the following structure is designed to solve the above technical problems.

[0064] See also Figure 5-Figure 10 The cleaning mechanism 5 includes a second support frame 53, a cleaning box 54 is fixedly connected to the upper side of the second support frame 53, a second top plate 51 is fixedly connected to the upper side of the cleaning box 54, a gear box 55 is fixedly connected to one side of the cleaning box 54, and a feed port and a discharge port are respectively provided on both sides of the cleaning box 54, and a rubber curtain 52 is fixedly connected to the feed port and the discharge port.

[0065] Specifically, the feed port is used to pass the uncleaned metal plate, the discharge port is used to pass the cleaned metal plate, and the rubber curtain 52 is used to prevent oxide layer fragments from splashing out from the inside of the cleaning box 54 when the high-pressure water gun is sprayed.

[0066] A water delivery mechanism 56 is provided on the upper side of the second top plate 51, and the water delivery mechanism 56 includes a water tank 561, a water pump 562 is provided on one side of the water tank 561, a booster pump 563 is provided on one side of the water pump 562, a water outlet of the water tank 561 is connected to a water pumping end pipeline of the water pump 562, a water outlet of the water pump 562 is connected to an input end pipeline of the booster pump 563, and a first output end and a second output end of the booster pump 563 are fixedly connected to a first hose 564 and a second hose 567 respectively.

[0067] Specifically, the water tank 561 is used to store water that needs to be cleaned, the water pump 562 is used to extract the water that needs to be cleaned from the water tank 561, and the pressure pump 563 is used to pressurize and transport the extracted water, and transport it out from the first hose 564 and the second hose 567 respectively.

[0068] The other end of the first hose 564 passes through the second top plate 51 and is fixedly connected to the first main water pipe 565 . The first main water pipe 565 is fixedly connected to the cleaning box 54 . A plurality of third hoses 566 are evenly and fixedly connected to the lower side of the first main water pipe 565 .

[0069] Specifically, the first main water pipe 565 is used to transport the high-pressure water delivered by the first hose 564 from the inside of the third hose 566 to the inside of the first flushing mechanism 57 .

[0070] A plurality of first flushing mechanisms 57 are evenly arranged inside the cleaning box 54, and the first flushing mechanism 57 includes two third hydraulic cylinders 571, and the two third hydraulic cylinders 571 are fixedly connected to the upper side of the second top plate 51, and the output end of each third hydraulic cylinder 571 is hinged with a fourth connecting rod 572, and the other end of the fourth connecting rod 572 is hinged with a fifth connecting rod 573, and the inside of the fifth connecting rod 573 is fixedly connected with a rotating rod 575, and the other end of the rotating rod 575 is connected to the side wall bearing of the cleaning box 54, and the lower end of the fifth connecting rod 573 is fixedly connected with a first water pipe 576, and the lower side of the first water pipe 576 is evenly fixedly connected with a plurality of first water spray heads 577.

[0071] Specifically, the extension and retraction of the output end of the third hydraulic cylinder 571 is used to control the rotation of the fourth connecting rod 572, thereby controlling the first water pipe 576 to rotate around the rotating rod 575 as the axis point, and then spraying the high-pressure water source inside the first water spray head 577 at different angles.

[0072] A third flushing mechanism 59 is provided on both sides of the plurality of first flushing mechanisms 57, and the third flushing mechanism 59 includes a plurality of second water spray heads 592. Both ends of each first water pipe 576 are fixedly connected with a fourth hose 593, and the second water spray head 592 is fixedly connected to the other end of the fourth hose 593. A connecting rod 591 is fixedly connected between every two second water spray heads 592. Two second motors 574 are fixedly connected to one side of the cleaning box 54, and the output end of the second motor 574 is fixedly connected to one of the second water spray heads 592.

[0073] Specifically, the rotation of the output end of the second motor 574 is used to control the rotation of the second water spray head 592, so that the high-pressure water source inside the second water spray head 592 is sprayed at different angles. The fourth hose 593 is made of soft material. When the second water spray head 592 rotates, it will not affect the first water pipe 576 and cause it to be displaced.

[0074] When the metal plate is brought into the interior of the cleaning box 54 by the roller, the water pump 562 extracts the water source required for cleaning from the water tank 561, and the pressure pump 563 pressurizes and transports the extracted water source, and transports it out from the first hose 564 and the second hose 567 respectively. The water source of the first hose 564 passes through the first main water pipe 565, and flows into the first water pipe 576 from each third hose 566 respectively, and finally is sprayed out from the first water head 577 and the second water head 592 in turn, while the water source of the second hose 567 passes through the second main water pipe 584 to reach the inside of the second water pipe 581, and finally is sprayed out from the output end of the third water head 582 in turn.

[0075] The metal plate is transported from right to left. There are six groups of first flushing mechanisms 57, of which four groups are close to the feed port. In the initial state, the output end of the third hydraulic cylinder 571 extends halfway. At this time, the first water spray head 577 sprays vertically downward, that is, high-pressure spray is performed on the upper side of the metal plate. Compared with the oblique spray, the impact force of the vertically sprayed high-pressure water source is concentrated in a smaller area, which can produce a stronger local impact on the oxide layer. Since the area of ​​the upper and lower sides of the metal plate is larger than that of the other four sides, more oxide layers are produced, and it needs to be flushed directly with high pressure.

[0076] Among them, the two groups of first flushing mechanisms 57 near the discharge port, in the initial state, the output end of the third hydraulic cylinder 571 is fully extended, at this time the first water pipe 576 rotates counterclockwise, and the first water spray head 577 sprays obliquely to the right, that is, high-pressure spray is performed on the left side of the metal plate. Since the area of ​​the other four sides of the metal plate is smaller than the upper and lower sides of the metal plate, the generated oxide layer is too small, and it is more suitable for oblique flushing. When the oxide layer is too small and flushing is performed directly, the impact force is too large, which is easy to cause damage to the metal plate surface and easy to cause it to shift during transportation.

[0077] The output end of the second motor 574 rotates to control the second water spray head 592 to face obliquely the front and rear sides of the metal plate, and sprays high-pressure water to wash the front and rear sides of the metal plate.

[0078] When the right side of the metal plate exceeds the two groups of first flushing mechanisms 57 near the feed port, the two groups of first flushing mechanisms 57 near the feed port cannot spray vertically downward to the upper side of the metal plate. At this time, the output end of the third hydraulic cylinder 571 of the two groups of first flushing mechanisms 57 near the feed port is completely retracted. At this time, the first water spray head 577 sprays obliquely to the left, that is, high-pressure spray is performed on the right side of the metal plate, and the left side of the metal plate has reached the two groups of first flushing mechanisms 57 near the discharge port. At this time, the output end of the third hydraulic cylinder 571 of the two groups of first flushing mechanisms 57 near the feed port is retracted by half. At this time, the first water spray heads 577 of the two groups of first flushing mechanisms 57 near the feed port spray vertically downward, thereby performing a secondary spray on the upper side of the metal plate to prevent the partial oxide layer of the metal plate from being completely removed.

[0079] While the first water spray head 577 and the second water spray head 592 spray water, the third water spray head 582 continues to spray the lower side of the metal plate, and the spray direction of the third water spray head 582 is vertically upward.

[0080] By changing the spray angles of the first water spray head 577 and the second water spray head 592, the oxide layer is sprayed on each surface of the metal plate, and in the process of movement of the metal plate, the spray states of the first water spray head 577 and the second water spray head 592 are changed in real time according to the moving distance of the metal plate, that is, direct spraying and diagonal spraying, thereby effectively preventing the four sides with few oxide layers from being damaged due to excessive direct spraying pressure, and the two sides with too much oxide layer from being damaged due to too small diagonal spraying pressure, which makes it impossible to completely remove the excessive oxide layer on the surface of the metal plate, thereby achieving the effect of high oxide layer cleaning efficiency and wide cleaning range.

[0081] Embodiment 4: During the cleaning process, due to the high-speed spraying of the high-pressure water gun, the oxide layer inside the metal plate falls off and becomes oxide layer fragments of different sizes, flying in the cleaning box. Some small oxide layer fragments will fall into the nozzle of the high-pressure water gun at the moment the high-pressure water gun is turned off. After the high-pressure water gun is started next time, the high-pressure water gun will spray the internal oxide layer fragments at high pressure onto the surface of the metal plate, thereby causing damage to the surface of the metal plate. Therefore, the following structure is designed to solve the above technical problems.

[0082] A second flushing mechanism 58 is provided at the lower part of the interior of the cleaning box 54, and the second flushing mechanism 58 includes a second main water pipe 584. The second main water pipe 584 is fixedly connected to the interior of the cleaning box 54, and a plurality of fifth hoses 583 are fixedly connected to the upper side of the second main water pipe 584. A third motor 586 is fixedly connected to one side of the gear box 55, and a plurality of fifth hoses 583 are provided inside the gear box 55.

[0083] Specifically, the high-pressure water source inside the second main water pipe 584 reaches the inside of the secondary water pipe 581 through the fifth hose 583, and then is sprayed out from the output end of the third sprinkler head 582 in sequence.

[0084] Several fifth hoses 583 are chain-connected to each other, the output end of the third motor 586 is fixedly connected to one of the second gears 585, the other end of each second gear 585 is fixedly connected to a second water pipe 581, the second water pipe 581 is fixedly connected to the other end of the fifth hose 583, and several third water spray heads 582 are fixedly connected to the upper side of the second water pipe 581.

[0085] Specifically, the rotation of the output end of the third motor 586 is used to control the rotation of the second gear 585, thereby controlling each secondary water pipe 581 to rotate, so that the third sprinkler head 582 sprays high-pressure water at different angles. The fifth hose 583 is made of soft material, and the rotation of the secondary water pipe 581 will not affect the second main water pipe 584 and cause it to be displaced.

[0086] After each metal plate spraying is completed, the first water spray head 577, the second water spray head 592 and the third water spray head 582 stop spraying and reset. Before the next metal plate spraying, the first water spray head 577 and the second water spray head 592 spray first to spray out the oxide layer fragments inside. The output end of the third hydraulic cylinder 571 stretches back and forth to control the first water spray head 577 and the second water spray head 592 to swing left and right to clean the oxide layer remaining on the upper surface of the drum. In order to prevent the oxide layer fragments sprayed by the first water spray head 577 and the second water spray head 592 from falling into To the inside of the third water spray head 582, before the first water spray head 577 and the second water spray head 592 spray, the output end of the third motor 586 rotates ninety degrees to make the spray port of the third water spray head 582 face downward. When the first water spray head 577 and the second water spray head 592 finish spraying, the third water spray head 582 starts to spray downward to spray the internal oxide layer fragments downward, so as to prevent the third water spray head 582 from spraying upward to spray the oxide layer fragments into the first water spray head 577 and the second water spray head 592 again or falling into the inside of the third water spray head 582 again after spraying.

[0087] Before cleaning the metal plate, the first water spray head 577, the second water spray head 592 and the third water spray head 582 are sprayed to clean the oxide layer fragments inside. While spraying, the first water spray head 577 and the second water spray head 592 are swung to indirectly clean the oxide layer fragments on the surface of the drum. When the first water spray head 577 and the second water spray head 592 are spraying the oxide layer fragments, the spraying direction of the third water spray head 582 is changed, which effectively prevents the oxide layer fragments sprayed by the first water spray head 577 and the second water spray head 592 from falling into the inside of the third water spray head 582, thereby achieving the effect of preventing damage to the surface of the metal plate and efficiently cleaning the oxide layer inside the water spray pipe.
