Description

Technical Field

[0001] This invention belongs to the field of cold rolling equipment technology, and more specifically, relates to an automated cold rolling mill for steel strip processing with edge trimming function. Background Technology

[0002] Cold rolling technology, as a core process in the fields of precision metal material processing and steel product manufacturing, directly determines the application value of steel strip products through its processing accuracy and finished product quality. During the cold rolling process of steel strip, the edges of the steel strip are prone to problems such as burrs, flash, and insufficient flatness due to rolling stress, equipment clearance, and other factors. If the edges are not effectively trimmed, it will not only affect subsequent deep processing steps such as cutting, welding, and bending of the steel strip, but also easily lead to product scrap due to edge defects, significantly reducing production efficiency and economic benefits.

[0003] The existing technology includes an automated cold rolling mill for steel strip processing with edge trimming function (authorization announcement number CN121289250B). This cold rolling mill drives the gear to rotate through the active roll end bushing. The gear meshes with the side toothed plate to drive vertical movement, which in turn drives the chuck to move. The steel strip is trimmed by the abrasive strip on the inner side of the chuck. At the same time, a miniature telescopic rod, locking bar, and locking groove are configured to control the start and stop of the edge trimming function. The movement stroke is limited by the bottom limit plate of the sliding shaft, and the component is reset by the compression spring. This improves the stability of the edge trimming process to a certain extent and solves the problems of inconvenient start and stop control of the edge trimming function and lack of reliability of component reset in traditional cold rolling mills. However, the edge-forming structure and supporting design of the cold rolling mill disclosed in this patent still have many technical defects: First, the cold rolling mill adopts a static friction edge-forming method of grinding with abrasive strips, which has low grinding efficiency, and the abrasive strips are easy to wear and the grinding effect is easy to decay with the use time, resulting in poor edge-forming effect; Second, the cold rolling mill is not equipped with a special anti-deviation device for the steel plate. During the continuous movement of the steel strip in the simultaneous cold rolling and edge-forming process, it is easy to shift laterally due to factors such as rolling traction force, grinding reaction force, and equipment operation vibration, resulting in the relative position of the clamping plate and the edge of the steel strip. Positional deviations result in uneven edge grinding and unpolished areas, severely reducing edge finishing accuracy. Thirdly, the cold rolling mill lacks a dedicated cleaning device for grinding debris. Metal debris generated during grinding easily adheres to the surface and edges of the steel strip, as well as rolling components such as the active roll and auxiliary roll. If the debris is not cleaned in time, it will not only scratch the surface of the steel strip and affect its smoothness, but also enter the gap between the rolls, causing wear on equipment components and reducing the service life of the cold rolling mill. At the same time, debris accumulation will also interfere with the normal continuous operation of edge finishing and rolling processes.

[0004] Based on the above problems, the applicant of this application requests the design of an automated cold rolling mill for steel strip processing with edge trimming function. Summary of the Invention

[0005] The purpose of this invention is to provide an automated cold rolling mill for steel strip processing with edge trimming function, so as to solve the technical problems in the prior art, such as low edge trimming and grinding efficiency of cold rolling mills, easy deviation of steel strip leading to poor edge trimming accuracy, and lack of special cleaning device for grinding debris affecting product quality and equipment life.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an automated cold rolling mill for steel strip processing with edge trimming function, comprising: frame; A cold rolling roll assembly, mounted on the frame, is used to process steel strip; The full-side sleeve plate is mirror-mounted on the left and right sides of the frame; A guide assembly, mirror-mounted on the edge sleeve plate, is used to limit the movement of the steel strip; A sanding assembly, mirror-mounted on the edge-sleeving plate and located on the side of the guide assembly away from the frame, is used to sand the edges of the steel strip. A cleaning component is mirror-mounted on the edge-mounting plate and located on the side of the abrasive component away from the frame; used to clean up debris that falls off during abrasion. The frosting component includes: The first driving component is mounted on the edge sleeve plate; A rotating wheel is fixed to the output end of the first driving component, and a recessed groove is provided on the outer surface of the rotating wheel for inserting a steel strip. Abrasive particles are provided on the bottom wall of the recessed groove for grinding the edge of the steel strip.

[0007] In conjunction with the above technical solution, the edge trimming sleeve includes a lifting sleeve and a telescopic sleeve. The top of the frame is provided with a second driving component, the output end of which is connected to a lead screw. A guide rail is installed on one side of the frame. The lifting sleeve is installed on the guide rail and is threadedly connected to the lead screw. The telescopic sleeve is installed in the cavity of the lifting sleeve through a third driving component.

[0008] In conjunction with the above technical solution, a limiting groove is formed on one side wall of the telescopic sleeve, and a connecting groove is formed in the limiting groove. A threaded top groove is connected in the connecting groove. By placing the guide component in the connecting groove and screwing a fastener into the threaded top groove, the guide component is abutted against each other, so that the guide component is fixed in the limiting groove.

[0009] In conjunction with the above technical solution, an exhaust port is provided on the side wall of the telescopic sleeve, and a through-hole is provided on the side wall of the lifting sleeve. Through the through-hole, the exhaust pipe is connected to the exhaust port, thereby enabling most of the debris to be sucked away.

[0010] In accordance with the above technical solution, the cleaning assembly includes an upper dust removal assembly and a lower dust removal assembly, which are mirror images of each other mounted on the edge-aligning sleeve plate. The upper dust removal assembly includes a squeezing roller and a dust removal part. The squeezing roller is rotatably mounted on a fixed plate, and the fixed plate is connected to the telescopic sleeve via a telescopic rod. A top spring is fitted around the telescopic rod. The rotating shaft of the squeezing roller passes through the fixed plate and is connected to a rotating disk. A protruding post is provided at the eccentric position of the rotating disk. The dust removal part is mounted on the lifting sleeve plate, and the protruding post is connected to the dust removal part via a connecting rod, so as to push the dust removal part to rotate when the squeezing roller rotates.

[0011] In accordance with the above technical solution, the chip removal unit includes a fourth driving component, a ratchet assembly, and a chip removal strip. The fourth driving component is mounted on the lifting sleeve plate, and the output end of the fourth driving component is connected to the chip removal strip via the ratchet assembly. A connecting block is fixed on the ratchet assembly, and the connecting block is hinged to the connecting rod. The top view of the chip removal strip is S-shaped, and a chip removal brush is adhered to the chip removal strip.

[0012] In conjunction with the above technical solution, a chip removal roller is rotatably connected to the fixed plate. A chip removal brush is attached to the outer surface of the chip removal roller to sweep away chips from the outer surface of the extrusion roller. The central shaft of the chip removal roller passes through the fixed plate. Pulling grooves are provided on both the rotating disk and the central shaft of the chip removal roller. A belt is sleeved in the pulling groove.

[0013] In accordance with the above technical solution, the lifting sleeve is provided with several mounting ports. By tightening fasteners in the mounting ports, the fourth driving component is fixed on the lifting sleeve.

[0014] In combination with the above technical solution, the initial angles of the chip-sweeping strips located on the left side of the frame and the chip-sweeping strips located on the right side of the frame are different, so as to alternately sweep the steel strips and avoid interference during rotation.

[0015] In conjunction with the above technical solution, a synchronization mechanism is provided between the two sets of upper chip removal components and between the two sets of lower chip removal components. The synchronization mechanism includes meshing teeth, a synchronization shaft, and a synchronization gear. A slot is provided on one side of the extrusion roller. The meshing teeth are arranged circumferentially on the side wall of the slot. The synchronization shaft passes through the fixing plates on the left and right sides, and the synchronization gear is fixed at both ends of the synchronization shaft and meshes with the meshing teeth.

[0016] The present invention provides an automated cold rolling mill for steel strip processing with edge trimming function, which has the following advantages compared with the prior art: 1. This invention uses a rotating wheel of a grinding component for dynamic grinding. The recessed groove of the rotating wheel is precisely adapted to the edge of the steel strip. The abrasive grains rotate at high speed with the rotating wheel to achieve dynamic friction grinding. Compared with the traditional static friction grinding strip method, the grinding efficiency is greatly improved. Moreover, the abrasive grains are evenly distributed and the wear rate is slow, which can maintain a stable edge smoothing effect for a long time. It effectively removes burrs and flash from the edge of the steel strip and improves the flatness of the steel strip edge. 2. The present invention provides a guide component on the edge trimming plate, which provides double limiting from both sides of the steel strip. This effectively prevents the steel strip from shifting laterally due to rolling traction force, grinding reaction force and other factors during the simultaneous cold rolling and edge trimming operations. It ensures that the relative position of the grinding component and the edge of the steel strip is always accurate, avoids uneven grinding and local un-grinding, and greatly improves the edge trimming accuracy. 3. This invention features a chip-collecting structure that combines an exhaust port with an exhaust duct, and is equipped with symmetrical cleaning components at the top and bottom. This allows for comprehensive chip cleaning from both the upper and lower surfaces of the steel strip and the surface of the extrusion rollers, achieving dual processing of chip removal and sweeping. This prevents metal chips from adhering and scratching the surface of the steel strip, or from accumulating in the gaps between the rollers and causing wear on equipment components. It ensures the surface smoothness of the steel strip, extends the service life of the cold rolling mill, and prevents chip accumulation from interfering with the continuous operation of the process. 4. The present invention ensures that the extrusion rollers and chip removal sections on the left and right sides of the frame operate synchronously through a synchronization mechanism. The chip removal strips on the left and right sides are designed with different initial angles to avoid interference. At the same time, the extrusion rollers and chip removal rollers rotate synchronously to achieve real-time chip removal. The smooth transmission and coordination of each component ensures the continuous and stable operation of edge trimming and cold rolling, thereby improving the overall production efficiency.

[0026] The present invention will now describe an automated cold rolling mill for steel strip processing with edge trimming function.

[0027] like Figures 1 to 9 As shown, this invention provides an automated cold rolling mill for steel strip processing with edge trimming function, including a frame 1, a cold rolling roll group 2, an edge trimming sleeve 3, a guide assembly 4, a grinding assembly 5, and a cleaning assembly 6. The cold rolling roll group 2 is mounted on the frame 1 and is used for cold rolling and forming steel strip. The cold rolling roll group 2 adopts an existing mature cold rolling roll structure, and the roll spacing and rolling speed can be adjusted according to the steel strip processing requirements. The edge trimming sleeve 3 is mirror-mounted on the left and right sides of the frame 1 and is the basic mounting carrier for edge trimming operations. The guide assembly 4 is mirror-mounted on the edge trimming sleeve 3 and abuts against the side of the steel strip to achieve lateral limit of the steel strip. The grinding assembly 5 is mirror-mounted on the edge trimming sleeve 3 and located on the side of the guide assembly 4 away from the frame 1. It is the core component for grinding the edge of the steel strip. The cleaning assembly 6 is mirror-mounted on the edge trimming sleeve 3 and located on the side of the grinding assembly 5 away from the frame 1 to achieve comprehensive cleaning of grinding debris.

[0028] like Figure 1 and Figure 3 As shown, in this embodiment, the edge-aligning sleeve 3 includes a lifting sleeve 31 and a telescopic sleeve 32. A second driving component 7 is fixedly installed at the top of the frame 1. The second driving component 7 is a servo motor, and its output end is connected to a lead screw 8. Guide rails 9 are vertically installed on both the left and right sides of the frame 1. The lifting sleeve 31 is slidably installed on the guide rails 9, and the inner side of the lifting sleeve 31 is provided with a threaded hole that matches the lead screw 8 and is threadedly connected to the lead screw 8. The telescopic sleeve 32 is installed in the cavity of the lifting sleeve 31 through a third driving component 10. The third driving component 10 is an electric push rod, whose fixed end is connected to the inner wall of the lifting sleeve 31, and its telescopic end is connected to the telescopic sleeve 32. Before operation, based on the thickness of the steel strip, the second drive component 7 is activated to drive the lead screw 8 to rotate. The lead screw 8 drives the lifting sleeve 31 to move vertically along the guide rail 9, adjusting the overall height of the edge sleeve 3. Based on the width of the steel strip, the third drive component 10 is activated to push the telescopic sleeve 32 to move horizontally, adjusting the distance between the edge sleeves 3 on both sides of the frame 1, so as to achieve precise matching between the equipment and the steel strip specifications.

[0029] like Figure 8As shown, furthermore, a limiting groove 321 is formed on the side wall of the telescopic sleeve 32 facing the steel strip. A connecting groove 322 is formed in the limiting groove 321, and the connecting groove 322 is connected to a threaded top groove 323. Before operation, the guide assembly 4 is placed in the connecting groove 322 and pushed to the innermost position of the connecting groove 322. Then, a fastener 12 is screwed into the threaded top groove 323. The fastener 12 is a fastening bolt, and its end abuts against the roller shaft of the guide assembly 4 to fix the guide assembly 4. The guide assembly 4 is a guide roller. The guide roller abuts against the side of the steel strip. The guide rollers on both sides form a double limiting for the steel strip, effectively preventing the steel strip from shifting laterally during conveying and processing.

[0030] like Figure 3 , Figure 5 and Figure 9 As shown, in this embodiment, the abrasive assembly 5 includes a first driving component 51 and a rotating wheel 52. The first driving component 51 is a high-speed variable frequency motor, which is fixed to the telescopic sleeve 32 by a mounting base. The rotating wheel 52 is fixedly installed at the output end of the first driving component 51. A recessed groove 521 adapted to the edge of the steel strip is opened on the outer surface of the rotating wheel 52. The edge of the steel strip can be accurately inserted into the recessed groove 521. Abrasive grains are evenly embedded on the bottom wall of the recessed groove 521. The abrasive grains are diamond abrasive grains, which have high hardness and good wear resistance. During operation, the first driving component 51 is started to drive the rotating wheel 52 to rotate at high speed. The abrasive grains 522 move in a circular motion with the rotating wheel 52, forming dynamic friction with the edge of the steel strip, quickly removing burrs and flash from the edge of the steel strip. Compared with traditional static friction grinding, the grinding efficiency is improved, and the flatness of the edge of the steel strip after grinding is higher.

[0031] like Figure 2 and Figure 4 As shown, the side wall of the telescopic sleeve 32 is provided with an exhaust port 324, and the side wall of the lifting sleeve 31 is provided with a corresponding opening 311. During operation, the exhaust pipe is passed through the opening 311 and sealed to the exhaust port 324. The other end of the exhaust pipe is connected to an industrial exhaust fan. After the exhaust fan is started, most of the metal shavings generated by the grinding component 5 can be directly sucked away and collected into the shavings collection box to achieve preliminary cleaning of the shavings.

[0032] like Figure 2 As shown, in this embodiment, the cleaning component 6 includes an upper chip sweeping component 61 and a lower chip sweeping component 62. The upper chip sweeping component 61 and the lower chip sweeping component 62 are mounted on the telescopic sleeve 32 of the side sleeve plate 3 in a mirror image, and respectively perform chip sweeping operations on the upper and lower surfaces of the steel strip. The two have the same structure. The upper chip sweeping component 61 will be used as an example for detailed description below.

[0033] like Figure 3 and Figure 6As shown, the upper chip removal assembly 61 includes a pressing roller 611, a chip removal part 612, a fixed plate 613, a telescopic rod 614, and a top spring 615. One end of the fixed plate 613 is connected to the telescopic sleeve 32 through the telescopic rod 614. The telescopic rod 614 is a telescopic metal rod, and a top spring 615 is sleeved around it. One end of the top spring 615 abuts against the telescopic sleeve 32, and the other end abuts against the fixed plate 613, providing elastic pressure to the fixed plate 613 towards the steel strip. The pressing roller 611 is rotatably mounted on the fixed plate 613 through a rotating shaft. The elastic pressure of the top spring 615 makes the pressing roller 611 fit tightly against the surface of the steel strip. When the steel strip moves along the conveying direction, it drives the pressing roller 611 to rotate synchronously.

[0034] like Figure 6 and Figure 7 As shown, the end of the shaft of the extrusion roller 611 away from the steel strip passes through the fixed plate 613 and is fixedly connected to the rotating disk 616. A protrusion 6161 is fixedly provided at the eccentric position of the rotating disk 616. The chip-sweeping part 612 is installed on the lifting sleeve 31 and includes a fourth drive component 6121, a ratchet assembly 6122, and a chip-sweeping strip 6123. The fourth drive component 6121 is an electric push rod. The lifting sleeve 31 has several mounting holes 312. By screwing fastening bolts into the mounting holes 312, the fourth drive component 6121 can be fixed in different positions. It is compatible with steel belts of different specifications; the output end of the fourth drive component 6121 is inserted into the ratchet assembly 6122 for connection. The ratchet assembly 6122 is existing technology and includes an outer ring, an inner ring, and a ratchet structure. The ratchet structure is located on the outer ring and the inner ring, enabling unidirectional rotation of the connected chip sweeper 6123. A connecting block 6124 is fixed on the outer ring of the ratchet assembly 6122. The connecting block 6124 and the protrusion 6161 are hinged through a connecting rod 617. The two ends of the connecting rod 617 are movably connected to the protrusion 6161 and the connecting block 6124, respectively. Figure 3 As shown, rotating the connecting block 6124 counterclockwise causes the outer ring of the ratchet assembly 6122 to rotate. The outer ring then drives the inner ring to rotate via the ratchet structure, which in turn drives the connected chip removal strip 6123 to rotate. When the connecting block 6124 is rotated clockwise, only the outer ring of the ratchet assembly 6122 can rotate. The inner ring, due to the rotational inertia of the chip removal strip 6123, still rotates counterclockwise.

[0035] When the extrusion roller 611 rotates with the steel strip, it drives the rotating disk 616 to rotate synchronously. The protrusion 6161 on the rotating disk 616 performs eccentric circular motion, which pulls the connecting block 6124 to swing back and forth through the connecting rod 617, thereby pulling the ratchet assembly 6122 to swing back and forth. Figure 3For example, when the ratchet assembly 6122 swings once, the chip sweeping bar 6123 will rotate counterclockwise. As the connecting rod 617 continues to pull the connecting block 6124 to swing back and forth, the chip sweeping bar 6123 will continue to rotate counterclockwise. The top view of the chip sweeping bar 6123 is S-shaped, and a high-density nylon chip sweeping brush is bonded to the side facing the steel strip. The continuously rotating chip sweeping bar 6123 can thoroughly clean the debris on the surface and edge of the steel strip. The S-shaped structure increases the chip sweeping contact area and improves the chip sweeping cleanliness.

[0036] like Figure 6 As shown, furthermore, a chip removal roller 618 is rotatably connected to the fixed plate 613 via a rotating shaft. The chip removal roller 618 is in contact with the extrusion roller 611, and a fine chip removal brush (not shown in the attached figure) is adhered to its outer surface for real-time chip removal from the outer surface of the extrusion roller 611. The end of the central shaft of the chip removal roller 618 away from the steel strip passes through the fixed plate 613. Both the rotating disk 616 and the central shaft of the chip removal roller 618 are provided with pull grooves, and a transmission belt 619 is sleeved between the two pull grooves. When the extrusion roller 611 rotates, the chip removal roller 618 is driven to rotate synchronously through the belt 619. The chip removal brush rotates with the chip removal roller 618, cleaning the debris attached to the surface of the extrusion roller 611 in a timely manner, preventing the debris from scratching the surface of the steel strip as the extrusion roller 611 rotates.

[0037] In this embodiment, the initial installation angles of the chip sweeping strip 6123 located on the left side of the frame 1 and the chip sweeping strip 6123 located on the right side of the frame 1 differ by 30-120°, so that the chip sweeping strips 6123 on both sides work alternately during the reciprocating rotation chip sweeping process, avoiding collision and interference between the two during rotation, and ensuring the continuous and stable operation of the chip sweeping process.

[0038] like Figure 6As shown, in addition, a synchronization mechanism 13 is provided between the two sets of upper chip-sweeping assemblies 61 and between the two sets of lower chip-sweeping assemblies 62. The synchronization mechanism 13 includes meshing teeth 131, a synchronization shaft 132 and a synchronization gear 133. A slot 6111 is opened on one side of the extrusion roller 611. The meshing teeth 131 are evenly arranged in a circle on the inner side wall of the slot 6111. The synchronization shaft 132 is a long metal shaft that horizontally passes through the fixing plates 613 on the left and right sides of the frame 1. Synchronization gears 133 are fixedly installed at both ends of the synchronization shaft 132. The synchronization gears 133 extend into the slot 6111 and mesh with the meshing teeth 131. When the steel belt drives the extrusion roller 611 on one side to rotate, the meshing teeth 131 drive the synchronous gear 133 to rotate. The synchronous gear 133 drives the synchronous gear 133 on the other side and the extrusion roller 611 to rotate synchronously through the synchronous shaft 132, ensuring that the extrusion rollers 611 on the left and right sides of the frame 1 rotate at the same speed. This keeps the chip-sweeping action of the chip-sweeping sections 612 on both sides synchronized, improves the overall chip-sweeping effect and the consistency of the edge-trimming operation, and further avoids collisions and interference between the chip-sweeping strips 6123 on both sides during rotation, ensuring the continuous and stable operation of the chip-sweeping process.

[0039] The workflow of this invention is as follows: Equipment debugging: According to the width and thickness of the steel strip to be processed, start the second drive component 7 to adjust the vertical height of the lifting sleeve 31, start the third drive component 10 to adjust the horizontal distance of the telescopic sleeve 32, fix the limit roller 11 with fastener 12, and adjust the installation position of the fourth drive component 6121 so that the chip sweeping part 612 is adapted to the position of the steel strip. Feeding and conveying: The steel strip to be cold rolled is fed into the cold rolling roll group 2 of the frame 1. The cold rolling roll group 2 starts to cold roll the steel strip. The steel strip moves along the conveying direction. The guide components 4 on both sides provide double limit for the steel strip to prevent it from deviating. Edge grinding: When the steel strip moves to the position of the grinding component 5, the first driving component 51 is activated to drive the rotating wheel 52 to rotate at high speed. The abrasive grains dynamically grind the edge of the steel strip to remove burrs and flash. At the same time, the industrial exhaust fan is activated to suck away and collect most of the grinding debris through the exhaust port 324 and the exhaust pipe. Debris removal: The polished steel belt continues to move to the cleaning component 6. The steel belt drives the extrusion roller 611 to rotate. The extrusion roller 611 drives the chip removal strip 6123 of the chip removal part 612 to rotate continuously through the rotating disk 616 and the connecting rod 617, cleaning the residual debris on the surface and edge of the steel belt. At the same time, the extrusion roller 611 drives the chip removal roller 618 to rotate through the belt 619, removing chips from the surface of the extrusion roller 611 in real time.
