Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cold rolling of stainless steel, and particularly to a continuous cold rolling device for stainless steel. Background Art
[0002] In the rolling process of the steel strip, when the steel strip passes through the roll gap defined by the upper and lower rolls, it undergoes plastic-elastic deformation under the rolling pressure of the upper and lower rolls, resulting in the thinning of the steel strip, and thus obtaining a steel strip with a certain thickness. Due to the great extrusion force generated during the rolling process on the steel strip, the crystal grains of the steel strip are flattened, elongated, the crystal lattice is distorted and deformed, and the crystal grains are broken, causing the plasticity of the steel strip to decrease, the hardness and strength to increase, and the phenomenon of work hardening to occur. At the same time, a large amount of deformation heat is generated during the rolling process of the steel strip, causing the temperature of the strip and the rolls to rise. Excessive roll surface temperature will cause the hardness of the hardened layer of the work roll to decrease, affecting the surface quality of the strip and the roll life. The increase in roll temperature and the uneven distribution of roll temperature will damage the normal roll shape, directly affecting the strip shape and dimensional accuracy of the strip.
[0003] During the rolling process, due to factors such as the uneven chemical composition and structure of the strip, the uneven original thickness of the steel strip, and the rolling of the roll along the same direction on the surface of the steel strip, the rolled steel strip has a large elasticity, making it difficult to control the thickness of the rolled steel strip, and the internal stress of the steel strip accumulates in the same direction, affecting the quality of the steel strip.
[0004] When the difference between the original thickness and the rolled thickness of the steel strip is relatively large, it is often necessary to use multiple sets of rolls to gradually roll the steel strip with the original thickness, that is, multiple sets of rolls are arranged in a line, and the roll gap between the upper and lower rolls is gradually reduced along the moving direction of the steel strip. Moreover, after the rolls are worn, it is necessary to stop the machine for replacement, greatly reducing the production efficiency. Summary of the Invention

Detailed Description of the Embodiment
[0030] The following is a detailed description of the specific embodiment of the present application with reference to the accompanying drawings. It should be understood that the specific embodiment described herein is only for the purpose of illustrating and explaining the present application, and is not used to limit the present application.
[0031] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a continuous cold rolling device for stainless steel, including a base 1 and two cold rolling roll groups 2. The base 1 is fixed on the ground, and mounting plates 11 are arranged on both sides of the base 1. The two cold rolling roll groups 2 are stacked vertically between the two mounting plates 11, and the steel strip passes through between the two cold rolling roll groups 2. Each end of each cold rolling roll group 2 is respectively passed through the two mounting plates 11, and a motor 21 for driving the cold rolling roll group 2 to rotate is connected to one end of each cold rolling roll group 2, and the motor 21 is fixed on the mounting plate 11. Stabilizing rings 3 are sleeved at both ends of each cold rolling roll group 2, and a impurity removing structure 4 for cleaning the surfaces of the cold rolling roll group 2 and the steel strip is arranged between the two stabilizing rings 3. The impurity removing structure 4 is located in front of the cold rolling roll group 2. After the surface of the steel strip is cleaned by the impurity removing structure 4, it then enters the cold rolling roll group 2 for rolling. A roll changing structure 5 connected to the impurity removing structure 4 is also installed on one of the stabilizing rings 3, and the impurity removing structure 4 controls the operation of the roll changing structure 5.
[0032] An adjusting groove 111 is opened at the lower end of each mounting plate 11. One of the cold rolling roll groups 2 is installed to rotate in the adjusting groove 111, and a lifting adjusting member 12 is also installed in each adjusting groove 111. The two lifting adjusting members 12 are respectively connected to both ends of the cold rolling roll group 2 located in the adjusting groove 111. The staff adjusts the position of the cold rolling roll group 2 in the adjusting groove 111 through the lifting adjusting member 12, thereby changing the roll gap between it and the other cold rolling roll group 2 to adapt to rolling steel strips of different thicknesses. And a support member 13 is provided on the base 1. The support member 13 is located in front of the mounting plate 11 to support the horizontal movement of the steel strip to form a feeding end.
[0033] Please refer to Figures 2 to 4 , each cold rolling roll group 2 includes a central shaft 22. The central shaft 22 is rotatably installed between the two mounting plates 11 and is connected to the motor 21 at one end. A toothed disc 23 is fixedly connected to one end of the central shaft 22, and the motor 21 drives the central shaft 22 and the toothed disc 23 to rotate clockwise. External tooth structures are provided at both ends of the central shaft 22, and a number of third gears 24 are meshed with the external tooth structures. Each third gear 24 is connected to the adjacent mounting plate 11 to rotate; and deceleration rings 25 are sleeved at both ends of the central shaft 22. The inner ring surface of the deceleration ring 25 is provided with an internal tooth structure, and the internal tooth structure is meshed with each third gear 24 at the same end. The clockwise rotation of the central shaft 22 drives a number of third gears 24 to rotate counterclockwise, and a number of third gears 24 then drive the deceleration ring 25 to rotate clockwise. A number of grooves are equally spaced on the outer peripheral surface of the deceleration ring 25, and a movable collar 26 is arranged in each groove. One end of the collar 26 close to the mounting plate 11 is connected to a spring, and the spring is used for the collar 26 to reset after moving in the groove. A check member 251 is also installed in each groove to abut against the collar 26, and the check member 251 resists the reset of the collar 26 after the collar 26 moves.
[0034] A number of first rolling rolls 27 are provided on the outer ring of the central shaft 22. The number of first rolling rolls 27 are in contact with the outer peripheral surface of the central shaft 22 at equal intervals. A first gear is sleeved at both ends of each first rolling roll 27 and is inserted into the corresponding collar 26. The first gear meshes with the toothed disc 23, and the rotation of the toothed disc 23 drives the first rolling roll 27 to rotate counterclockwise. A second rolling roll 28 is arranged between two adjacent first rolling rolls 27. The second rolling roll 28 is in contact with the central shaft 22 and two adjacent first rolling rolls 27 at the same time. Both ends of the second rolling roll 28 are also inserted into the corresponding collar 26, and a second gear is sleeved at the end far from the toothed disc 23 and meshes with the first gear. The rotation of the first rolling roll 27 drives the second rolling roll 28 to rotate clockwise. It can be understood that the above embodiment is described with the cold rolling roll group 2 located above. The cold rolling roll group 2 located below moves towards each other, that is, in the opposite rotation direction to the above description.
[0035] When the cold rolling roll group 2 rotates to roll the steel strip, the motor 21 drives the central shaft 22 to rotate, and the toothed disc 23 rotates synchronously with the central shaft 22. The toothed disc 23 drives the first rolling roll 27 to rotate within the collar 26, and the first rolling roll 27 drives the second rolling roll 28 to rotate towards each other. At the same time, the central shaft 22 drives the third gear 24 to rotate, and the third gear 24 further drives the speed reduction ring 25 to rotate. The speed reduction ring 25 rotates in the same direction as the central shaft 22 and the rotation speed of the central shaft 22 is greater than the rotation speed of the speed reduction ring 25, that is, the linear velocity of the rotation of the first rolling roll 27 is greater than the linear velocity of the rotation of the speed reduction ring 25, so that although the rotation direction of the speed reduction ring 25 is opposite to the steel strip processing direction, the first rolling roll 27 still drives the steel strip to feed along the processing direction. The speed reduction ring 25 drives a number of first rolling rolls 27 to rotate in the direction opposite to the movement of the steel strip and is tangent to the steel strip at the feeding end. When the steel strip is in contact with a number of first rolling rolls 27 at the feeding end, the steel strip is rolled by the first rolling roll 27 to form an arc surface. When the steel strip continues to move, the first rolling roll 27 rolls the steel strip along the arc surface, increasing the thickness of the steel strip rolled at one time; the second rolling roll 28 then performs reverse secondary rolling on the steel strip rolled by the first rolling roll 27, reducing the elastic change after the steel strip is rolled and dispersing the stress concentration in the steel strip along the processing direction.
[0036] Please refer to Figure 2 、 Figure 5 and Figure 6, two stabilizing rings 3 are respectively sleeved on both ends of a plurality of first rollers 27 and a plurality of second rollers 28, and each first roller 27 and each second roller 28 are in contact with the inner wall surface of the stabilizing ring 3. On the inner ring surface of each stabilizing ring 3 away from the mounting plate 11, a discharge groove, a first feed groove and a second feed groove are sequentially arranged along the direction of rotation of the central axis 22. The discharge groove is located at the feed end of the base 1 and a discharge baffle 31 is hinged in the discharge groove. The discharge baffle 31 prevents the first roller 27 and the second roller 28 from falling; a first feed baffle 32 and a second feed baffle 33 are respectively hinged in the first feed groove and the second feed groove to close the first feed groove and the second feed groove. Further, one end of the discharge baffle 31 is connected with a slider 34, and the slider 34 is in contact with the collar 26; when the discharge baffle 31 rotates, it drives the slider 34 to drive the abutted collar 26 to move synchronously, and the collar 26 drives the spring to compress and store energy. And a stop strip 35 is further arranged on the inner ring surface of each stabilizing ring 3. One end of the stop strip 35 is close to the discharge baffle 31, and the other end crosses the second feed baffle 33. A notch is also arranged on the stop strip 35 between the first feed baffle 32 and the second feed baffle 33 for the collar 26 to pass through and reset.
[0037] Please refer to Figure 1 , Figure 2 and Figure 5 , the impurity removal structure 4 is connected to the outer wall surface of the stabilizing ring 3 and corresponds to the discharge baffle 31, and includes a rotating rod 41 and a plurality of cleaning rods 42. The rotating rod 41 is arranged parallel to the central axis 22. Both ends of the rotating rod 41 are fixedly connected to two stabilizing rings 3 of each group. A plurality of cleaning rods 42 are movably sleeved on the rotating rod 41 at equal intervals. One end of each cleaning rod 42 extends towards the central axis 22 and is in contact with the adjacent first roller 27 or second roller 28. The movement of the first roller 27 or the second roller 28 drives the cleaning rod 42 to swing; the other end of the cleaning rod 42 extends downward close to the steel strip, and a torsion spring is further arranged on the cleaning rod 42 for the cleaning rod 42 to reset after swinging.
[0038] Further, the impurity removal structure 4 further includes an impurity removal rod 43 for scraping impurities on the surface of the steel strip. The impurity removal rod 43 includes a cross bar part and two vertical rod parts. The two vertical rod parts are sleeved on the rotating rod 41. One end of each vertical rod part is in contact with the adjacent discharge baffle 31, and the other end extends towards the steel strip. The cross bar part is connected to one ends of the two vertical rod parts close to the steel strip, and the cross bar part corresponds to the cleaning rod 42. When the cleaning rod 42 swings, it abuts against the cross bar part and pushes the impurity removal rod 43 to rotate. Both ends of the cross bar part are connected with telescopic members 431 towards the steel strip. Scraper plates 432 are arranged at one ends of the two telescopic members 431 close to the steel strip. Both ends of the scraper plate 432 are hinged to the ends of the telescopic members 431 and are in contact with the steel strip. The swinging of the cross bar part of the impurity removal rod 43 drives the telescopic members 431 to move synchronously, and the scraper plate 432 is always abutted against the surface of the steel strip and reciprocates under the action of the telescopic members 431.
[0039] When the impurity removal structure 4 is removing impurities, the cleaning rod 42 abuts against the rotating first roller 27 to scrape off the impurities adhering to the first roller 27, and the first roller 27 rotates with the reduction ring 25, driving the cleaning rod 42 to swing, and the other end of the cleaning rod 42 abuts against the impurity removal rod 43 to swing synchronously to scrape off the impurities adhering to the surface of the steel strip. When the first roller 27 moves to be separated from the cleaning rod 42, the cleaning rod 42 and the impurity removal rod 43 return to their original positions under the action of the torsion spring, and the cleaning rod 42 abuts against the second roller 28, and the above actions are repeated to clean and remove impurities from the second roller 28.
[0040] See also Figure 1 , Figures 5 to 7 The roller changing structure 5 includes a discharging structure 51, which is used to control the discharging baffle 31 to open and release the worn first roller 27 or second roller 28. The discharging structure 51 includes a discharging rod 511, an elastic member 512 and a roller receiving plate 513. The discharging rod 511 is sleeved on the rotating rod 41. The middle section of the discharging rod 511 abuts against the end of the cleaning rod 42 away from the central axis 22, and is located on the other side of the abutment of the impurity removal rod 43 (that is, the cleaning rod 42 is sandwiched between the discharging rod 511 and the impurity removal rod 43). The two ends of the discharging rod 511 extend toward the adjacent stabilizing ring 3 to form a control end. The control end is extended with a locking block 5111 that abuts against the surface of the stabilizing ring 3 and corresponds to the discharging baffle 31, and abuts against the discharging baffle 31 so as not to rotate. The elastic member 512 is connected between the discharge baffle 31 and the impurity removal rod 43. When the impurity removal rod 43 swings, the discharge baffle 31 is pulled by the elastic member 512 to rotate and open the discharge chute. The roller receiving plate 513 is fixed below the discharge chute to receive the first roller 27 or the second roller 28 dropped from the discharge chute.
[0041] When the first roller 27 is worn, the cleaning rod 42 abuts against the surface of the first roller 27. The first roller 27 rotates with the reduction ring 25, driving the cleaning rod 42 to swing. The swinging of the cleaning rod 42 drives the discharge rod 511 to swing. The locking block 5111 at the control end of the discharge rod 511 moves to abut against the discharge baffle 31. At the same time, the cleaning rod 42 pushes the impurity removal rod 43 to swing, disengages from the abutment against the discharge baffle 31 and pulls the elastic member 512 to extend. The cleaning rod 42 located at the worn part of the first roller 27 is worn and its diameter becomes smaller. As a result, the cleaning rod 42 cannot resist the cleaning rod 42 to continue to swing, so that the cleaning rod 42 at this position is first restored to its original position, pushing the discharge rod 511 to move in the opposite direction, driving the locking block 5111 at the control end to move, releasing the resistance to the discharge baffle 31, and then pulling the discharge baffle 31 to rotate under the contraction of the extended elastic member 512, opening the discharge chute, and driving the ring 26 to move away from the first roller 27. Under the action of gravity, the first roller 27 falls into the roller receiving plate 513 along the discharge chute.
[0042] A first feed group 52 and a second feed group 53 are also connected to the stable ring 3, which are used to separately store the first roller 27 and the second roller 28. The first feed group 52 includes two first chutes 521 and two locking rods 522. The two chutes 521 are respectively connected to the two stable rings 3 and correspond to the first feed chute. The first roller 27 is stored between the two chutes 521. Each locking rod 522 is arranged at one end of the first feed baffle 32, and is arranged in a staggered manner in an upper and lower double-layer structure. The upper rod of the locking rod 522 is inserted into the first feed baffle 32 to lock the first feed baffle 32 and support the first roller 27 located above the first feed baffle 32. The lower rod of the locking rod 522 abuts against the inner wall surface of the stable ring 3 and corresponds to the spring of the connecting collar 26, so that after the collar 26 moves, it can push the lower rod of the locking rod 522 to move, and then drive the upper rod to move, releasing the locking of the first feed baffle 32. The second feed group 53 is arranged in the same way as the first feed group 52 and includes two second chutes 531, and the second chutes 531 are used to store the second roller 28. Preferably in this embodiment, clearance grooves are provided on the collars 26 sleeved at both ends of several second rollers 28, and the clearance grooves correspond to the locking rods 522, so that the collars 26 at both ends of the second roller 28 can move over the locking rods 522 and move to the second chute 531 to control the replacement of the second roller 28 in the second chute 531.
[0043] When the worn first roller 27 falls from the discharge chute, the deceleration ring 25 drives the displaced collar 26 to move to the first feed group 52. The collar 26 abuts against the locking rod 522 to move, releasing the locking of the first feed baffle 32. The first roller 27 in the chute 521 pushes the first feed baffle 32 to rotate and open, so that the first roller 27 is clamped in the groove of the deceleration ring 25 through the first feed chute. The shaft end of the first roller 27 abuts against the check member 251 to move, releasing the abutment against the lower end of the collar 26. Then the adjacent second roller 28 pushes the first feed baffle 32 to reset, and the collar 26 resets under the action of the spring, releasing the abutment against the locking rod 522. The locking rod 522 also returns to its original position to lock the first feed baffle 32. It can be understood that when replacing the second roller 28, it is also the same as described above.
[0044] The above-described embodiments only represent the implementation manners of the present invention, but should not be construed as limiting the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
