Description

A leveling machine for cold-rolled strip processing Technical Field

[0001] This utility model relates to the field of cold-rolled strip steel processing, and in particular to a leveling machine for cold-rolled strip steel processing. Background Technology

[0002] In the processing of cold-rolled strip steel, the leveling process is a crucial step in ensuring strip quality and improving its flatness and subsequent processing performance. Traditional leveling techniques mainly rely on a series of carefully designed, alternating work rolls to perform multiple bending operations on the strip. This process aims to redistribute the internal stress of the strip, thereby improving its flatness.

[0003] However, in actual production applications, traditional strip leveling technology has revealed some significant limitations. During the leveling process, friction and compression between the strip and the work rolls easily generate inclusions such as metal shavings. Simultaneously, impurities from the external environment may also enter the leveling system. These inclusions, including metal shavings and other impurities, accumulate inside the leveler, adhering to the surface of the work rolls, between the roll gaps, and other critical parts of the leveler. This not only increases the difficulty and workload of equipment cleaning and maintenance but also makes thorough cleaning difficult. The presence of impurities adversely affects the surface quality of the strip, causing defects such as scratches and indentations, reducing the strip's appearance quality and performance stability, and may also affect the normal operation of the leveler.

[0004] Therefore, there is a need to provide a leveling machine for processing cold-rolled strip steel. Summary of the Invention

[0005] To overcome the shortcomings of lacking a way to clean up the mixed metal shavings, this utility model provides a leveling machine for cold-rolled strip steel processing.

[0006] A leveling machine for cold-rolled strip steel processing includes a support platform, a support frame, a fixed platform, lower pressure rollers, bearings, a transmission assembly, a motor, and upper pressure rollers. The support platform has a support frame on top, and a fixed platform is also located on top of the support platform. Four lower pressure rollers are rotatably mounted between the front and rear sides inside the support frame. The front and rear ends of each lower pressure roller are connected to the rotatable connection of the support frame via bearings. Four sliding grooves are provided on both the front and rear sides inside the support frame, and bearings are slidably installed within each of these grooves. An upper pressure roller is rotatably mounted between two bearings on the same side. A transmission assembly is provided between the front and rear ends of the upper pressure rollers, and a transmission assembly is also provided between the front and rear ends of the four lower pressure rollers. The machine also includes a cleaning assembly located within the fixed platform.

[0007] More preferably, the cleaning component includes a collection frame, an electromagnetic block, a feed inlet, and a material collection frame. Three collection frames are evenly spaced inside the fixed platform. A feed inlet is provided at the top of each collection frame. An electromagnetic block is installed inside each collection frame. The material collection frame is slidably provided at the bottom of the fixed platform.

[0008] More preferably, it also includes connecting plates and cylinders. Cylinders are symmetrically installed on the left and right sides of the top of the support frame. A connecting plate is provided between the piston rods of the two cylinders on the front side and a connecting plate is also provided between the piston rods of the two cylinders on the rear side. The two connecting plates are connected to the top of the transmission assembly connected to the upper pressure roller.

[0009] More preferably, it also includes guide rails, with guide rails provided on both the front and rear sides of the upper part of the support frame, and the conveying components are slidably connected to the adjacent guide rails.

[0010] More preferably, it also includes a receiving platform, with receiving platforms provided on both the left and right sides of the top of the fixed platform.

[0011] More preferably, the height of the collection frame is the same as the height of the lower pressure roller.

[0012] The beneficial effects and significant advancements of this utility model are as follows:

[0013] This invention utilizes an electromagnetic block design to powerfully attract metal scrap generated during leveling. This effectively prevents metal scrap from scattering everywhere. When it is necessary to clean up the scrap, simply disconnect the power supply to the electromagnetic block, and the metal scrap will fall from the collection box into the material collection box. This design makes scrap cleaning simple and efficient, eliminating the need for operators to spend a lot of time and effort cleaning up scrap scattered everywhere. Attached Figure Description

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example: A leveling machine for cold-rolled strip steel processing, as shown in Figures 1 to 6, includes a support platform 1, a support frame 2, a fixed platform 201, lower pressure rollers 3, bearings 4, a transmission assembly 5, a motor 6, an upper pressure roller 7, a connecting plate 8, a cylinder 9, a guide rail 10, a collection frame 11, an electromagnetic block 12, a feed inlet 13, a collection frame 14, and a receiving platform 15. The support platform 1 serves as the base support component of the leveling machine. The support frame 2 is connected to the top of the support platform 1, and the fixed platform 201 is also connected to the top of the support platform 1. The fixed platform 201 is located inside the support frame 2. Four lower pressure rollers 3 are rotatably connected at even intervals between the front and rear sides inside the support frame 2. The front and rear ends of each lower pressure roller 3 are connected to the rotatable connection point of the support frame 2 via bearings 4. Four evenly spaced grooves are provided on the rear side of the support frame 2. A bearing 4 is slidably installed in each groove. An upper pressure roller 7 is rotatably installed between two bearings 4 on the same side. The bearings 4 allow the lower pressure roller 3 and the upper pressure roller 7 to rotate smoothly on the support frame 2, reducing rotational friction. The upper pressure roller 7 cooperates with the lower pressure roller 3 to extrude and level the cold-rolled strip. The rotation of the lower pressure roller 3 drives the cold-rolled strip to move. Under the extrusion action of the upper and lower pressure rollers 3, the bending, wavy, and other deformations of the strip are eliminated, making its surface smooth. A transmission assembly 5 is connected between the front and rear ends of the four upper pressure rollers 7, and also between the front and rear ends of the four lower pressure rollers 3. The transmission assemblies 5 are used to transmit power, enabling the four lower pressure rollers 3 and the four upper pressure rollers 7 to move together. The support frame 2 is symmetrically and vertically mounted on the left and right sides of its top. Connecting plates 8 connect the piston rods of the two front cylinders 9 and the two rear cylinders 9. These connecting plates 8 are connected to the top of the transmission assembly 5 attached to the upper pressure roller 7. By activating the cylinders 9, power is transmitted to the upper pressure roller 7, allowing it to move up and down with the extension and retraction of the piston rods, thus adjusting the gap between the upper and lower pressure rollers 3. Motors 6 are mounted on the two front transmission assemblies 5. Guide rails 10 are vertically connected to the center of the front and rear sides of the upper part of the support frame 2. The transmission assemblies are slidably connected to the adjacent guide rails 10, which provide vertical support for the up and down movement of the transmission assemblies 5. For guiding purposes, the fixed platform 201 has a U-shaped design. Three collection frames 11 are evenly spaced inside the fixed platform 201. The collection frames 11 are used to collect waste generated during the leveling process. Each collection frame 11 is located between two adjacent lower pressure rollers 3, and the height of the collection frame 11 is the same as the height of the lower pressure roller 3. A feed inlet 13 is provided at the top of each collection frame 11. Electromagnetic blocks 12 are installed inside each collection frame 11. The electromagnetic blocks 12 generate a magnetic field to attract the metal waste generated during the leveling process, preventing waste from splashing everywhere and facilitating centralized collection and processing. A material collection frame 14 is slidably connected to the bottom of the fixed platform 201. The bottom of the collection frames 11 is open, and the material collection frame 14 is located below the four collection frames 11, facilitating the falling of waste into the lower material collection frame 14.Two receiving platforms 15 are connected to the top left and right sides of the fixed platform 201. The two receiving platforms 15 are located outside the leftmost and rightmost lower pressure rollers 3, respectively, and are at the same height as the lower pressure rollers 3. The receiving platforms 15 are used to receive the cold-rolled strip before and after leveling, allowing the cold-rolled strip to smoothly enter and leave the leveling machine, ensuring smooth strip conveying.

[0023] When using a leveling machine for cold-rolled strip steel processing, first, based on the thickness of the cold-rolled strip steel to be leveled, adjust the gap between the upper pressure roller 7 and the lower pressure roller 3 by activating cylinder 9. The piston rod of cylinder 9 extends and retracts, causing the connecting plate 8 to move, which in turn moves the upper pressure roller 7 up and down, making the gap between the upper pressure roller 7 and the lower pressure roller 3 slightly smaller than the strip steel thickness, ensuring sufficient pressure is applied to the strip steel during the leveling process. Simultaneously, check whether the electromagnetic block 12 is properly energized and can generate a magnetic field to attract metal scrap.

[0024] The cold-rolled strip to be leveled is placed on the receiving platform 15 located outside the leftmost lower pressure roller 3, ensuring that the strip is neatly arranged without twisting or knotting. Motors 6 are started sequentially, driving the lower pressure roller 3 and upper pressure roller 7 to rotate synchronously via the transmission assembly 5. During rotation, the lower pressure roller 3 contacts the strip, and friction propels the strip forward. After entering the space between the upper and lower pressure rollers 7 and 3, the internal stress of the strip is redistributed under the squeezing action of the rollers, eliminating deformations such as bending and undulation, and gradually smoothing the surface.

[0025] During the leveling process, the electromagnetic block 12 generates a magnetic field to attract the metal waste generated during the leveling process, preventing the waste from splashing everywhere. The waste enters the collection frame 11 through the feed port 13 at the top of the collection frame 11.

[0026] The leveled strip is output from the receiving platform 15 located outside the rightmost lower pressure roller 3. The operator should collect and organize the leveled strip in a timely manner.

[0027] After the leveling work is completed, first turn off motor 6 to stop the rotation of the lower pressure roller 3 and upper pressure roller 7. Then turn off the power to cylinder 9 and electromagnetic block 12. At this time, the electromagnetic block 12 will lose its magnetic field, and the metal scrap will naturally fall into the collection frame 14 below. After collection, pull the collection frame 14 out from the bottom of the fixed platform 201 and clean out the metal scrap. After cleaning, put the collection frame 14 back in its original position.

[0028] By performing the above operations, the leveling machine for cold-rolled strip steel processing can be used normally.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
