Description

Technical Field

[0001] The invention relates to the technical field of steel strip uncoiling and cutting, and in particular to an uncoiling and cutting device for cold-rolled steel strip processing. Background Art

[0002] Cold-rolled steel strip is made of hot-rolled coil as raw material and is rolled below the recrystallization temperature at room temperature. It includes plates and coils. The ones that are very long and delivered in coils are called steel strips, also known as coils. Cold-rolled steel has good properties, that is, through cold rolling, thinner and higher precision cold-rolled strip steel can be obtained.

[0003] Since the cold-rolled steel strip is sold in coils, it is necessary to uncoil the cold-rolled steel strip before using it, and then perform operations such as straightening and cutting on the cold-rolled steel strip. The existing invention patent with patent publication number CN118595823A discloses an uncoiling and cutting device for cold-rolled steel strip processing and a cutting method thereof, which contacts the port position of the cold-rolled steel coil with the hydraulic box, forcing the hydraulic box to move down along the inner wall of the rotating track, and the piston frame will squeeze the internal liquid, forcing the cutting blade to extend outward to achieve the cutting of the bandage and complete the uncoiling process of the cold-rolled steel coil. Through the application of the above-mentioned components, the equipment can automatically cut off the bandage on the outside of the cold-rolled steel coil after completing the feeding, eliminating the manual operation of the process and avoiding the mechanical force remaining in the cold-rolled steel coil from causing damage to external personnel.

[0004] However, this invention patent also has corresponding defects: its cutting blade moves along the axial direction of the steel strip coil to both sides of the steel strip coil, thereby cutting the bandage, and driving the hydraulic box downward through the end of the steel strip coil, so that the piston frame squeezes the liquid to drive the cutting blade to move. Therefore, only when the center line of the hydraulic box passes through the center of the steel strip coil, that is, the hydraulic box is perpendicular to the surface of the steel strip, the cutting blade is closest to the surface of the steel strip and perpendicular to the surface of the steel strip, and the bandage basically fits the surface of the steel strip. When the steel strip drives the hydraulic box to move to drive the cutting blade to move, the hydraulic box and the surface of the steel strip are in an inclined state. At this time, the distance between the cutting blade and the steel strip is large, and the cutting blade is also in an inclined state relative to the bandage. This not only makes it easy for the cutting blade to move to the surface of the bandage, but also the inclined cutting blade makes it difficult to cut the bandage. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, the present invention provides a coiling and cutting device for cold-rolled steel strip processing, comprising a base 1 and a cutting device 2 arranged on the base 1, the cutting device 2 is used for cutting the steel strip, the base 1 is also provided with a support plate 3, the support plate 3 is provided with a rotating device 4 and an adjusting structure 5, the rotating device 4 is provided with an expansion and contraction reel 9 for fixing the rolled steel strip, the adjusting structure 5 is provided with an end lifting structure 6, the end lifting structure 6 is provided with a rolling clamping structure 7, and a rolling support device 8 is provided between the rolling clamping structure 7 and the cutting device 2.

[0031] Among them, the adjustment structure 5 is used to adjust the end lifting structure 6 to be tangent to the outer surface of the rolled steel strip, the end lifting structure 6 is used to slide along the surface of the rolled steel strip until it contacts the end of the steel strip, and cut off the packaging strip on the rolled steel strip after lifting the end of the steel strip, the rolling clamping structure 7 is used to rolling clamp the lifted steel strip, and the rolling support device 8 is used to support the steel strip between the cutting device 2 and the rolling clamping structure 7.

[0032] In actual application of the present application, the rolled steel strip (i.e., the steel strip rolled into a disc) is placed on the expanding and contracting reel 9, and the rolled steel strip is fixed by the expanding and contracting reel 9. Then, the position of the end lifting structure 6 is adjusted by the adjusting structure 5 to contact the surface of the rolled steel strip. Then, the expanding and contracting reel 9 is driven by the rotating device 4 to drive the rolled steel strip to rotate until the end of the steel strip on the rolled steel strip contacts the end lifting structure 6.

[0033] The end lifting structure 6 lifts the end of the steel strip, at which time the rotating device 4 stops working, and then the end lifting structure 6 cuts off the packaging strip on the rolled steel strip (that is, the long strip fixed around the rolled steel strip). Since the end of the steel strip is lifted by the end lifting structure 6, the corresponding position on the packaging strip is arched outward by the end of the steel strip, and the distance between this part of the packaging strip and the surface of the rolled steel strip is larger, which makes it easier for the end lifting structure 6 to cut the packaging strip, ensuring that the packaging strip can be cut by the end lifting structure 6, and the steel strip can be released normally to pass through the rolling clamping structure 7 and the rolling support device 8 to the cutting device 2 in turn, without manual operation, avoiding the problem of the end of the rolled steel strip ejecting outward after the packaging strip is cut off, causing harm to the workers.

[0034] The rolling clamping structure 7 is used to limit the end of the steel strip after the packaging strip is cut from ejecting outwards, and to make rolling contact with the steel strip to ensure that the steel strip can be normally released to the cutting device 2 for cutting.

[0035] In this embodiment, after the coiled steel strip is released, the steel strip is clamped on both sides of the steel strip by a traction device, such as two traction rollers rotating in opposite directions, to perform a traction movement.

[0036] In this embodiment, the cutting device 2, the rotating device 4, the rolling support device 8 and the expanding and shrinking reel 9 are all existing technologies. For example, the cutting device 2 can be a cutter that can move up and down and a cutting platform, the rotating device 4 can be a motor, the rolling support device 8 is a plurality of rollers of different heights for supporting the movement of the steel strip, and the expanding and shrinking reel 9 is a device for fixing the rolled steel strip on the existing uncoiler. The principles of the above existing technologies will not be elaborated on here.

[0037] The adjustment structure 5 includes a horizontal moving device 501 arranged on the support plate 3, the horizontal moving device 501 is provided with a vertical plate 507 which is slidably connected to the top of the support plate 3, the vertical plate 507 is provided with a vertical moving device 502, the vertical moving device 502 is provided with a connecting frame 503, a plurality of connecting plates 504 are connected to the connecting frame 503 with equal intervals in rotation along the horizontal direction, an adjustment plate 505 parallel to the expansion and contraction reel 9 is fixedly connected to the plurality of connecting plates 504, and a limit assembly 506 for limiting the rotation of the connecting plate 504 is provided on the connecting frame 503.

[0038] The horizontal moving device 501 moves in a horizontal direction perpendicular to the expansion and contraction reel 9 , and the vertical moving device 502 moves in a vertical direction. When the adjustment plate 505 rises to the highest point, the maximum height of the adjustment plate 505 is greater than the top height of the support plate 3 .

[0039] After the rolled steel strip is fixed on the expansion and contraction reel 9, the adjusting structure 5 adjusts the position of the end lifting structure 6, and adjusts the horizontal and vertical positions of the connecting frame 503, the connecting plate 504 and the adjusting plate 505 through the horizontal moving device 501 and the vertical moving device 502, and adjusts the angles of the adjusting plate 505 and the connecting plate 504. Subsequently, the limiting assembly 506 is used to limit the rotation of one of the connecting plates 504 to ensure the stability of the adjusting plate 505 during use, and to make the end lifting structure 6 on the adjusting plate 505 stably contact with the surface of the rolled steel strip, so that the end of the rolled steel strip can contact with the end lifting structure 6 during the rotation process.

[0040] The plurality of connecting plates 504 are used to ensure the stability of the adjusting plate 505 .

[0041] In order to prevent the rolled steel strip from interfering with the process of being installed on the expansion and contraction reel 9, when the adjustment plate 505 is raised to the maximum height through the vertical moving device 502, the height of the adjustment plate 505 must be higher than the top height of the support plate 3 to prevent the end lifting structure 6 from interfering with the installation of the rolled steel strip.

[0042] In this embodiment, the limit assembly 506 is a prior art. For example, the limit assembly 506 includes an electric push rod arranged on the connecting frame 503, and a limit plate is arranged at the end of the electric push rod. A plurality of limit teeth are evenly distributed on the circumference of one connecting plate 504 around its own rotation center. The limit plate is driven by the electric push rod to be inserted between the corresponding two limit teeth, so as to limit the rotation of the connecting plate 504. Alternatively, other technical solutions can be used to achieve the position limitation of the connecting plate 504. The technical principles will not be elaborated on here.

[0043] A sliding groove 508 is formed on the top of the support plate 3 , and the bottom of the vertical plate 507 is slidably connected in the sliding groove 508 .

[0044] By inserting the vertical plate 507 into the slide groove 508, the stability of the vertical plate 507 during use is improved, thereby improving the stability of the end lifting structure 6 during use.

[0045] The end lifting structure 6 includes a connecting strip 601 which is rotatably connected to one side of the adjusting plate 505 through a torsion spring, and one side of the connecting strip 601 is provided with a plurality of arc-shaped lifting plates 602 which are used to adhere to the surface of the rolled steel strip and lift the end of the steel strip at equal intervals along its own length direction, and the thickness of the arc-shaped lifting plate 602 gradually decreases in the direction away from the adjusting plate 505, and the end of the arc-shaped lifting plate 602 is in the shape of a thin blade, and a linear moving device 603 which moves axially along the expansion and contraction reel 9 is provided on the top of the adjusting plate 505, and a cutting component 604 for cutting the packaging tape is provided on the linear moving device 603.

[0046] After the end lifting structure 6 is adjusted in position by the adjustment structure 5, the thin blade-shaped end of the arc-shaped lifting plate 602 contacts the surface of the rolled steel strip. In the process of the rolled steel strip being driven to rotate by the expansion and contraction reel 9, the arc-shaped lifting plate 602 contacts the end of the steel strip, and the thin blade-shaped end of the arc-shaped lifting plate 602 is inserted between the end of the steel strip and the surface of the rolled steel strip, so that the end of the steel strip is lifted, and the corresponding part of the packaging strip is arched through the steel strip. At this time, the rotating device 4 stops working, and then the linear moving device 603 drives the cutting assembly 604 to move to cut off multiple packaging strips on the rolled steel strip in turn. The end of the steel strip is lifted by the arc-shaped lifting plate 602, which ensures that the packaging strip can be effectively cut by the cutting assembly 604.

[0047] The connecting strip 601 is connected to the adjusting plate 505 via a torsion spring, so that the arc-shaped lifting plate 602 has a certain buffer when contacting with the surface of the rolled steel strip.

[0048] The arrangement of multiple arc-shaped lifting plates 602 can not only avoid the packaging belt through the space between two adjacent arc-shaped lifting plates 602, but also make the end of the steel belt be evenly supported by the multiple arc-shaped lifting plates 602, thereby preventing the steel belt from being squeezed by the arc-shaped lifting plates 602 and deformed.

[0049] The hardness of the arc-shaped lifting plate 602 is less than that of the steel strip, so as to avoid the arc-shaped lifting plate 602 from damaging the surface of the steel strip when sliding along the surface of the rolled steel strip.

[0050] The cutting assembly 604 includes a moving seat 605 arranged on the linear moving device 603, and a strip plate 606 is arranged on the moving seat 605. A plurality of cutting knives 607 are evenly spaced on the side of the strip plate 606 facing the arc-shaped lifting plate 602, and each cutting knife 607 is located between two adjacent arc-shaped lifting plates 602.

[0051] The linear moving device 603 drives the moving seat 605 to drive the strip plate 606 to move along the axial direction of the expansion and contraction reel 9, so that the strip plate 606 drives the multiple cutting knives 607 to move, and cuts the multiple packaging belts in sequence during the movement.

[0052] In this embodiment, the moving direction of the cutting knife 607 when cutting the packaging tape is away from the vertical plate 507, so that the strip plate 606 has a larger movement range when moving, avoiding interference with the support plate 3.

[0053] A receiving groove 608 is formed on the side of the arc-shaped lifting plate 602 away from the vertical moving device 502 , and the receiving groove 608 is used to receive the cutting knife 607 .

[0054] By providing an accommodating groove 608 to accommodate the corresponding cutting knife 607, the cutting knife 607 is prevented from being located between two adjacent arc-shaped lifting plates 602 and pressed down on the surface of the packaging belt when the arc-shaped lifting plate 602 contacts the surface of the rolled steel belt, thereby avoiding the problem that the cutting knife 607 cannot cut the packaging belt.

[0055] The rolling clamping structure 7 includes a bracket 701 arranged on the adjustment plate 505, and a horizontal plate 702 parallel to the strip plate 606 is arranged on the bracket 701, and a plurality of arc guide plates 703 are arranged on the horizontal plate 702, and each arc guide plate 703 is located between two adjacent arc lifting plates 602. A movable plate 704 is slidably connected to the bracket 701, and a roller 705 is rotatably connected to the movable plate 704. A telescopic device 706 is arranged on one side of the movable plate 704, and the roller 705 is driven by the telescopic device 706 to approach or move away from the plurality of arc guide plates 703.

[0056] After the packaging tape is cut, the rotating device 4 continues to work, and the cutting knife 607 is reset, so that the end of the steel tape passes through the multiple arc guide plates 703 and the roller 705 in turn. At this time, the telescopic device 706 drives the movable plate 704 to drive the roller 705 to approach the multiple arc guide plates 703, thereby fixing the steel tape between the arc guide plates 703 and the roller 705, avoiding the problem of the steel tape popping out and causing harm to the workers; secondly, the multiple arc lifting plates 602 continue to press down on the surface of the rolled steel tape, which can avoid the problem of the rolled steel tape loosening during the release process.

[0057] In this embodiment, the horizontal moving device 501, the vertical moving device 502 and the linear moving device 603 are all existing technologies. For example, the corresponding components can be driven to move by rotating a screw driven by a motor. The telescopic device 706 is also existing technology, such as an electric push rod, and the technical principles will not be elaborated on here.
