Description

Technical Field

[0001] This utility model relates to the field of steel strip application technology, and in particular to a leveling and shearing machine. Background Technology

[0002] The reason for cutting coiled steel strips into segments is primarily to meet the production needs of different scenarios. Conventional shearing is mostly done manually, which is time-consuming and labor-intensive, and the cut edges often have burrs and are uneven. Furthermore, after shearing, the coiled steel strip tends to curl, which not only easily scratches workers but also makes handling the strip inconvenient. Therefore, a leveling process is needed to facilitate equipment use. The conventional leveling method involves winding the steel strip onto a pulley system before shearing to initially level it. However, this method has limited effectiveness, and the cut steel strip still retains some degree of curl. Additionally, the segments of steel strip vary in length, making it impossible to standardize their length, which undoubtedly leads to waste and increased costs. Utility Model Content

[0032] Optionally, a guide cover 39 is horizontally provided on the left side wall of the fixing block 26 corresponding to the threading hole 27. The inlet of the guide cover 39 at the left end is wide-mouthed and located at the top of the transmission roller 5. A reinforcing rib 40 connected to the guide cover 39 is provided on the side wall of the fixing block 26. When the steel strip is threaded, the guide cover 39 can act as a guide, making it easier for the steel strip to be threaded into the threading hole 27.

[0033] Optionally, a housing 53 is provided on the two clamping plates 32 to cover the locating shaft 34, the eccentric disk 35, and the locating sleeve 36. The housing 53 can provide dust protection for the locating shaft 34, the eccentric disk 35, and the locating sleeve 36.

[0034] Optionally, a left bracket 41 is provided at the left end of each of the two support plates 2, and the front and rear ends of a left guide roller 42 are respectively movably engaged with the left bracket 41 on the corresponding side; a right bracket 43 is provided at the right end of each of the two support plates 2, and the front and rear ends of a right guide roller 44 are respectively movably engaged with the right bracket 43 on the corresponding side. The left guide roller 42 and the right guide roller 44 can reduce friction with the steel strip, thus reducing the probability of damage to the steel strip.

[0035] Optionally, a limiting mechanism is provided between the two support plates 2 on the left side of the transmission roller 5. The limiting mechanism includes a limiting fixing seat 45, which is connected to the support plates 2 on both sides through a horizontally arranged limiting fixing plate 46. A sliding groove 47 is opened in the middle of the limiting fixing seat 45 along its length direction. Moving blocks 48 are symmetrically arranged on the surfaces of the limiting fixing seats 45 on the front and rear sides. The moving blocks 48 are movably engaged in the sliding groove 47 by a slider 49 set at their bottom. Locking holes 50 that cooperate with the limiting fixing seat 45 are provided on the moving blocks 48. A limiting plate 51 is provided on each moving block 48. Limiting pulleys 52 are provided on the surfaces of the limiting plates 51 at the left and right ends. By adjusting the positions of the two movable blocks 48, the movable blocks 48 slide within the grooves 47 of the limiting fixing seat 45. When each limiting pulley 52 on the limiting plate 51 abuts against both sides of the steel strip, bolts are passed through the locking holes 50 to fix the positions of the two movable blocks 48 and the limiting fixing seat 45. This limiting mechanism can limit and guide the steel strip as it enters, allowing it to enter vertically between each driven roller 5 and the pressing mechanism, thus enabling a more efficient leveling process.

[0036] Before use, the outer end of the steel strip is inserted through the left ends of the two support plates 2, passes between the pressing mechanism and the driven roller 5, and finally extends outward through the threading hole 27 and the exit channel 28. During use, the lifting motor 17 is started via the control device. The output shaft of the lifting motor 17 drives the right-side screw jack 14, causing the screw on that side to extend downward. Simultaneously, the right-side screw jack 14 drives the left-side screw jack 14 via the linkage sleeve 15, causing the left-side screw to extend downward synchronously. As the screws on both sides move downward, the connecting seat 22 pushes the lower pressure plate 19 horizontally downward. The guide rods 23 act as guides to ensure that the movement of the lower pressure plate 19 is always vertical. The lifting motor 17 stops until each lower pressure roller 21 contacts the steel strip and abuts the steel strip against each driven roller 5. At this point, manual fine-tuning can be performed by turning the handwheel 16 to synchronize the two screw jacks 14, thereby controlling each lower pressure roller 21 and each driven roller 5 to clamp the steel strip. The purpose of manual adjustment is to both clamp the steel strip tightly and not affect the movement of the steel strip driven by the transmission roller 5. Then, the stepper motor 6 is started. The output shaft of the stepper motor 6 drives the drive gear 8 to rotate through the drive roller 7, which in turn drives the left linkage gear 11 to rotate through the transmission gear 12. As the first linkage gear 11 on the left rotates, it drives the two driven gears 9 above it to rotate synchronously. The driven gear 9 on the right drives the second linkage gear 11 on the left to rotate, and so on, until all the driven gears 9 rotate synchronously, ultimately achieving the purpose of all driven rollers 5 rotating in the same direction, thereby rubbing the steel strip to move to the right. During the movement, the steel strip is continuously leveled. Stepper motor 6 not only drives the active roller 7 to rotate, but also calculates the rotation distance. When the steel strip reaches the specified length, the shearing motor 33 is started by the control device. The output shaft of the shearing motor 33 drives the eccentric disk 35 to rotate through the clamping shaft 34, which in turn drives the clamping sleeve 36 to move up and down. When the clamping sleeve 36 moves downward, it drives the linkage seat 30 and the cutter head 31 to move downward through the clamping seat 37 and the clamping head 38, so that the cutter head 31 is pressed tightly against the side wall of the fixed clamping block 26, thereby quickly applying force to cut the steel strip. The cut steel strip then slides outward along the right guide roller 44. Its structure is compact and reasonable, and the whole adopts mechanical operation, integrating leveling and shearing. The cut position of the steel strip is flat and burr-free, and the overall leveling effect is good. The leveled steel strip will not curl, further reducing the probability of safety risks. It is convenient to pick up and put away the sheared steel strip. In addition, the overall length of the sheared steel strip is consistent, thereby reducing the generation of waste and reducing cost expenditure, solving the problems existing in the prior art.
