Description

Technical Field

[0001] The invention relates to the technical field of plate roughing mills, and in particular to a plate roughing mill with a loading and unloading structure. Background Art

[0002] A sheet roughing mill is a type of equipment used for metal forming processing. Its working principle is mainly based on the plastic deformation and rolling principle of metals. A roughing mill usually consists of two rollers that move relative to each other, and the roller shafts are driven by a motor. When the metal sheet passes between the two rollers, they flatten, shrink, stretch, and form the metal sheet into the desired shape. Roughing mills can efficiently form metal sheets, are suitable for large-scale production, have high forming accuracy, and reduce material waste. They are widely used in many industries to meet the needs of different industries.

[0003] In the plate rough rolling mill in the prior art, loading and unloading is a key step in the rough rolling process of the heated plate. For larger-sized plates or continuous production, conveyor belts or rollers are usually used to transport the heated plates from the heating furnace to the rolling mill entrance. This method can achieve continuous and stable plate transportation and improve production efficiency; however, due to the long-distance transportation of the plates at the top of the conveyor belt or roller, the plates will be affected by vibration, causing their position at the top of the conveyor belt or roller to shift. No relevant limiting and correcting mechanisms are set on both sides of the conveyor belt or roller in the prior art, resulting in the subsequent plates failing to be rolled in the center position of the rollers after entering the rolling mill, reducing the rolling accuracy of the plates, which will have an adverse effect on the rough rolling quality of the plates. Summary of the invention

[0014] Optionally, the driving mechanism includes a mounting plate, which is mounted on an outer wall of one side of the two movable plates that are close to each other, and a top end of the mounting plate is flush with the plurality of feeding rollers.

[0015] Optionally, a lifting plate is slidably mounted inside the mounting plate, a telescopic cylinder is rotatably mounted on the inner bottom surface of the mounting plate, and the telescopic end of the telescopic cylinder is connected to the lifting plate.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the present invention, in the process of automatic feeding of metal sheets by the feeding rollers, the limit mechanism is set to push the limits on both sides of the metal sheets, and has a corrective effect on the metal sheets to be processed, so that the metal sheets can be located in the center position of the two rollers for rough rolling during the process of entering the shell, thereby improving the accuracy of the rough rolling of the metal sheets by the two rollers, and further improving the rough rolling quality of the metal sheets.

[0018] 2. In the present invention, while the two limit plates are moving toward each other, they are in close contact with the two sides of the metal plate and have an extrusion and shaping effect on the two sides of the metal plate, ensuring that the two sides of the metal plate are in a horizontal state; and after the metal plate moves to between the two limit plates and is extruded and shaped on both sides, the metal plate is driven to rotate 90 degrees with the help of a driving mechanism, so that the other two sides of the metal plate are rotated to a position close to the two limit plates. As the two limit plates continue to move toward the direction of approach, the other two sides of the metal plate can also be extruded and shaped, thereby reducing the deformation of the four sides of the metal plate before rolling, which affects the quality of the subsequent rough rolling by the two rollers.

[0019] 3. In the present invention, when there is a small amount of iron oxide scale that has not been cleaned off on the surface of the metal plate, after the two limit plates are moved in the direction of approaching each other to abut against the two sides of the metal plate, the rotating frames on the top of the two second sliders are controlled to rotate on the top of the metal plate in turn, and after the rotating frames rotate on the top of the limit plates, the rotating plates inside are controlled to rotate 90 degrees, and the scrapers or wire brushes are controlled to extend from the inside of the corresponding rectangular grooves, so that when the rotating frames rotate to the top of the metal plate, the iron oxide scale that has not been automatically cleaned off on the top of the metal plate can be cleaned off with the help of the scrapers or wire brushes. The alternating cooperation of the two rotating frames and the rotating plates inside them can comprehensively remove the iron oxide scale on the top of the metal plate, thereby improving the effect of cleaning the iron oxide scale on the top of the metal plate.

[0020] 4. In the invention, after cleaning the oxidized iron sheet on the top of the metal plate, one end of the metal plate is driven to move between the two friction blocks by means of the forward and reverse rotation of multiple feeding rollers, and then the telescopic ends of the two fourth electric telescopic rods can be controlled to extend together, driving the two friction blocks to move in a direction close to each other and tightly abut against both sides of one end of the metal plate. With the help of the rotation of the two driving motors, the metal plate at this time can be turned over, so that the top of the metal plate rotates to the top, and the above steps of cleaning the oxidized iron sheet on the top of the metal plate are repeated, so that the upper and lower surfaces of the metal plate can be cleaned, avoiding the problem that the spray mechanism cannot fully spray high-pressure water on the bottom of the metal plate.

[0039] As a technical optimization solution of the present invention, the tops of the two limit plates 8 are provided with second slide grooves 23, the interiors of the two second slide grooves 23 are provided with second sliders 24, and the tops of the two second sliders 24 are provided with rotating racks 21.

[0040] As a technical optimization solution of the present invention, a rotating plate 22 is rotatably mounted inside the two rotating frames 21 through a rotating shaft 26, and two rectangular grooves 27 are provided inside the rotating plate 22. A fourth driving device is preset inside the two rotating frames 21, and the output ends of the two fourth driving devices are respectively connected to one end of the rotating shaft 26, so as to drive the rotating plate 22 to rotate and adjust inside the rotating frame 21.

[0041] As a technical optimization solution of the present invention, two third electric telescopic rods 28 are installed inside the two rectangular grooves 27, wherein the telescopic ends of the two third electric telescopic rods 28 are jointly installed with a scraper 29, and the telescopic ends of the other two third electric telescopic rods 28 are jointly installed with a wire brush 30.

[0042] As a technical optimization solution of the present invention, the outer walls of the two limiting plates 8 that are away from each other are both equipped with a driving motor 20, and the output ends of the two driving motors 20 are both equipped with a fourth electric telescopic rod 25, and the telescopic ends of the two fourth electric telescopic rods 25 are both equipped with a friction block 19.

[0043] As a technical optimization solution of the present invention, the driving mechanism includes a mounting plate 7, which is mounted on the outer wall of one side where the two movable plates 5 are close to each other, and the top of the mounting plate 7 is flush with the multiple feeding rollers 6.

[0044] As a technical optimization solution of the present invention, a lifting plate 12 is slidably installed inside the mounting plate 7, and a telescopic cylinder 13 is rotatably installed on the inner bottom surface of the mounting plate 7, and the telescopic end of the telescopic cylinder 13 is connected to the lifting plate 12. A driving device is preset inside the mounting plate 7, and the output end of the driving device is connected to the bottom end of the telescopic cylinder 13. After the telescopic end of the telescopic cylinder 13 is extended upward, the lifting plate 12 is driven to extend upward from the inside of the mounting plate 7, so that the driving device can drive the telescopic cylinder 13 and the lifting plate 12 to rotate and adjust together above the mounting plate 7.

[0045] In the present invention, when the user uses the device, the metal sheet after the heat treatment will be placed on the top of multiple loading rollers 6 through relevant transfer equipment. With the help of the rotation of the multiple loading rollers 6, the metal sheet is transported in the direction close to the shell 2 until the metal sheet moves between the two rolling rollers 3. After the metal sheet is roughly rolled by the two rolling rollers 3, the metal sheet falls on the top of multiple unloading rollers 31. The multiple unloading rollers 31 can drive the rough-rolled metal sheet to move toward the next finishing equipment, thereby achieving the effect of automatic loading and unloading of the metal sheet and improving the efficiency of rolling the metal sheet.

[0046] Since two limit plates 8 are set on the top of the multiple feeding rollers 6, and the two limit plates 8 can be adjusted by means of the extension and retraction of the corresponding two second electric telescopic ends of the telescopic rods 18, so that after the metal sheet moves toward the direction close to the shell 2 to between the two limit plates 8, the two limit plates 8 move toward the direction close to each other, push the two sides of the metal sheet to limit, and have a corrective effect on the metal sheet to be processed, so that the metal sheet can be located in the center position of the two rollers 3 for rough rolling processing during the process of entering the shell 2, thereby improving the accuracy of the two rollers 3 in rough rolling of the metal sheet.

[0047] At the same time, while the two limit plates 8 move toward the approaching direction, the telescopic ends of the multiple second electric telescopic rods 18 can be controlled to continue to extend, driving the two limit plates 8 to continue to move in the approaching direction, tightly abutting against the two sides of the metal plate, and having an extrusion and shaping effect on the two sides of the metal plate to ensure that the two sides of the metal plate are in a horizontal state; and after the metal plate moves to the two limit plates 8 and is extruded and shaped on both sides, the telescopic end of the telescopic cylinder 13 inside the mounting plate 7 can be controlled to extend upward, pushing the lifting plate 12 to extend upward from the inside of the mounting plate 7, and driving the metal plate to move upward together, and then the lifting plate 12 can be controlled to drive the metal plate to rotate 90 degrees, so that the other two sides of the metal plate rotate to a position close to the two limit plates 8, as the telescopic end of the telescopic cylinder 13 contracts downward, driving the metal plate to move downward and reset, the two limit plates 8 continue to move in the approaching direction, and the other two sides of the metal plate can also be extruded and shaped, reducing the deformation of the four sides of the metal plate before rolling, affecting the quality of the subsequent rough rolling of the two rollers 3;

[0048] Moreover, after some metal sheets have been rolled once by the two rolling rollers 3, it is necessary to control the rotation of the two rolling rollers 3 to drive the metal sheets to return to the top of the multiple feeding rollers 6 again, and then perform one or more rolling processes. After the metal sheets return to the top of the multiple feeding rollers 6 and are located between the two limit plates 8, the steps of extruding and shaping the four sides of the metal sheets by the two limit plates 8 can be repeated, so that after multiple rolling, the warping and deformation problems on the four sides of the metal sheets are improved, which is convenient for the subsequent processing of the metal sheets.

[0049] The metal sheet will be heated at high temperature before rolling, so that a dense layer of iron oxide scale will be formed on the surface of the metal sheet. If this layer of iron oxide scale cannot be removed before the two rollers 3 roll the metal sheet, it will be pressed into the surface of the strip by the rollers 3 during the rolling process, affecting its surface quality. In addition, the residual iron oxide scale will also accelerate the wear of the rollers 3 and reduce the service life of the rollers 3. Therefore, a spray mechanism is preset inside the shell 2 to spray high-pressure water on the surface of the metal sheet to clean up the iron oxide scale formed on the surface of the metal sheet. After the spray mechanism sprays water on the surface of the metal sheet, there will still be a small amount of iron oxide scale on the surface of the metal sheet that has not been cleaned up. The two limit plates 8 can be moved in a direction close to each other until they are in contact with both sides of the metal sheet. After the rotating frame 21 on the top of the two second sliders 24 is in the state, the rotating frame 21 is controlled to rotate on the top of the metal sheet in turn, and after the rotating frame 21 rotates on the top of the limit plate 8, the rotating plate 22 inside it is controlled to rotate 90 degrees, and the telescopic ends of the corresponding two third electric telescopic rods 28 are controlled to extend together, driving the scraper 29 or the wire brush 30 to extend from the inside of the corresponding rectangular groove 27, so that when the rotating frame 21 rotates to the top of the metal sheet, the scraper 29 or the wire brush 30 can be used to clean the oxidized iron scale on the top of the metal sheet that cannot be automatically cleaned off. The alternating cooperation of the two rotating frames 21 and the rotating plates 22 inside them and other components can comprehensively remove the oxidized iron scale on the top of the metal sheet, thereby improving the effect of cleaning the oxidized iron scale on the top of the metal sheet;

[0050] Moreover, in the process of scraping off the iron oxide scale on the top of the metal plate with the help of the scraper 29, the water that falls on the top of the metal plate and fails to evaporate quickly can also be scraped off, thereby preventing some water from remaining on the top of the metal plate, causing the temperature of the metal plate to drop faster, thereby affecting the subsequent rolling of the metal plate.

[0051] After cleaning the oxidized iron sheet on the top of the metal sheet, with the help of the forward and reverse rotation of multiple feeding rollers 6, one end of the metal sheet is driven to move between the two friction blocks 19, and then the telescopic ends of the two fourth electric telescopic rods 25 can be controlled to extend together, driving the two friction blocks 19 to move in a direction close to each other and tightly abut against both sides of one end of the metal sheet. With the help of the rotation of the two driving motors 20, the metal sheet at this time can be driven to turn over with the fourth electric telescopic rod 25 as the center of the circle, so that the top of the metal sheet rotates to the top, and the above steps of cleaning the oxidized iron sheet on the top of the metal sheet are repeated, so that the upper and lower surfaces of the metal sheet can be cleaned, avoiding the problem that the spray mechanism cannot fully spray high-pressure water on the bottom of the metal sheet.

[0052] The oxidized iron scale on the outer walls of two sides of the metal plate can be automatically rubbed away by the friction blocks 19 arranged on the outer walls of one side close to the two limit plates 8 when the metal plate is moved and transported by the multiple feeding rollers 6 toward the shell 2. After the metal plate is driven to rotate and adjust with the help of the lifting plate 12, the multiple feeding rollers 6 are synchronously rotated forward and backward to drive the metal plate to move back and forth between the two limit plates 8, so that the oxidized iron scale on the outer walls of the other two sides of the metal plate can be rubbed away by the two friction blocks 19 at the same time, thereby achieving the effect of completely removing the oxidized iron scale on the surface of the metal plate and improving the quality of the rolling of the metal plate by the rolling roller 3.

[0053] For example, after the metal sheet is rolled by the two rollers 3, it does not need to be transported to the next finishing process by means of multiple unloading rollers 31. The two rollers 3 can be rotated and cooperated to make the metal sheet fall on the top of the multiple loading rollers 6 and the mounting plate 7, and then one of the first sliders 14 is controlled to move in the direction away from the housing 2 inside the corresponding first slide 11, and then the telescopic ends of the two second electric telescopic rods 18 above the other first slider 14 are controlled to extend, driving the other limit plate 8 to move on the top of the multiple loading rollers 6, so that the metal sheet can be directly pushed off from the top of the multiple loading rollers 6, so as to achieve the effect of quickly unloading the metal sheet after the rough rolling process;

[0054] Furthermore, in order to improve the rough rolling efficiency of multiple metal sheets, after the first metal sheet is roughly rolled, Figure 8As shown, the two rotating frames 21 are controlled to rotate 90 degrees at the top of the corresponding limit plate 8 in the direction close to the other limit plate 8 in sequence, so that after the two rotating frames 21 rotate, the ends away from the second slider 24 are placed on the top of the other limit plate 8 respectively. According to the length of the metal sheet after rough rolling, the two second sliders 24 are controlled to move in the corresponding second slide groove 23 in the direction of approaching or moving away from each other, so as to drive the spacing between the two rotating rotating frames 21 to be adjusted. Then, the multiple screw rods 32 are controlled to rotate together, so as to drive the two moving plates 5 and other multiple components to move downward and adjust together, and the telescopic ends of the multiple first electric telescopic rods 16 are controlled to extend upward together, so as to push the two limit plates 8 to move upward and disengage from the multiple feeding rollers 6. After the top ends of the two rotating frames 21 move to a height suitable for a rolling roller 3 below, the metal sheet after rough rolling is transported toward the top of the multiple feeding rollers 6 as the two rolling rollers 3 rotate and cooperate. At this time, the metal sheet removed from between the two rolling rollers 3 will fall on the top of the two rotating frames 21, and then the next metal sheet can be placed on the multiple feeding rollers 6, and transport it to the top of the mounting plate 7 with the help of multiple feeding rollers 6, the first metal sheet located on the top of the two rotating frames 21 can be moved to a suitable position in the direction away from the shell body 2 along with the two first sliding blocks 14 in the corresponding first sliding grooves 11, and then the two rotating frames 21 are controlled to rotate and reset, so that the first metal sheet falls downward on the top of the multiple feeding rollers 6 away from the shell body 2 and is placed, after one of the first sliding blocks 14 is controlled to move and reset in the direction close to the shell body 2, the telescopic ends of the two second electric telescopic rods 18 above the other first sliding block 14 are controlled to extend, driving the other limiting plate 8 to push the first metal sheet that falls on the top of the multiple feeding rollers 6 at this time to be unloaded, and then the other first sliding block 14 is controlled to move and reset in the direction close to the shell body 2, and the telescopic ends of the multiple first electric telescopic rods 16 are controlled to retract and reset, and the multiple screw rods 32 drive the two moving plates 5 to move upward and reset, and continue to clean the oxide scale and extrude and shape the surface of the second metal sheet, so as to avoid the problem that the unloading process of one metal sheet is relatively slow, which affects the rough rolling processing efficiency of other subsequent metal sheets.
