Description

Technical Field

[0001] The utility model relates to steel material processing equipment, in particular to a strip steel uncoiling machine. Background Art

[0002] When producing steel pipes and steel frames, the raw steel strip needs to be uncoiled and cut into steel plates that meet the process requirements, and then the subsequent processing is started. When the steel strip is uncoiled, due to the change of its own tension and the impact caused by the cutting action, the steel strip is prone to deviation. The existing uncoiler usually adjusts the deviation by applying different downward pressures to the steel strip by the pressure roller. However, this deviation adjustment method will cause the steel strip to move horizontally frequently, which not only affects the uncoiling and shearing efficiency, but also easily causes scratches on the surface of the steel strip.

[0015] Reference Figure 1-2 A specific embodiment of the utility model includes a material roll stand 1 and a cutting machine 2. A first driving motor 3 is installed on the material roll stand 1. The first driving motor 3 is connected to a driving shaft 4. A first side plate 5 is fixedly installed on the side of the driving shaft 4 close to the first driving motor 3. A second side plate 6 is detachably installed on the other end of the driving shaft 4. A feeding roller 7 is installed on the feeding end of the cutting machine 2. A pressure roller 8 is installed above the feeding roller 7. Both ends of the pressure roller 8 are connected to the cutting machine 2 through a first oil cylinder 9 respectively. The feeding roller 7 is connected to the second driving motor 10. The pressure roller 8 is connected to the third driving motor 11. A shearing tool 12 is installed at the discharge end of the cutting machine 2 (the specific installation structure of the tool and the accompanying driving device belong to common knowledge and are not shown in the figure). A roller 13 is installed on the discharge side of the material roll stand 1 through a fourth oil cylinder 22. A ferrule 23 is detachably installed on the driving shaft 4. Before unwinding, first remove the second side plate 6, then insert the steel strip into the drive shaft 4 and sleeve it on the clamping sleeve 23, and then reinstall the second side plate 6 to fix the steel strip. Find the free end of the steel strip, then jog the first drive motor 3, slowly pass the free end of the steel strip over the roller 22, then between the feed roller 7 and the pressure roller 8, and finally pass under the shearing tool 12 to complete the loading.

[0016] Reference Figure 2-5Two second oil cylinders 14 are symmetrically installed on the top of the material roll rack 1. The angle between the axis of the second oil cylinder 14 and the vertical direction is 18°. The piston end of the second oil cylinder 14 is connected to a pressure wheel 15. The pressure wheel 15 is arranged horizontally. The inner side surface of the first side plate 5 is annularly provided with a plurality of grooves 16 with the center point of the driving shaft 4 as the central symmetrical point. The grooves 16 are arranged along the radial direction of the first side plate 5. The two ends of the grooves 16 are respectively installed with a third oil cylinder 17. The top of the groove 16 is movably installed with a top block 18, and the bottom of the top block 18 is connected to the third oil cylinder 17. The pressure wheel 15 is fixed on the connecting shaft 19. The two ends of the connecting shaft 19 are movably inserted into the socket 20 located at the piston end of the second oil cylinder 14. The outer side of the socket 20 is installed with a spring 21. The side wall of the pressure wheel 15 is in sliding contact with the spring 21. When the pressure wheel 15 moves left and right along the axis of the connecting shaft 19, the spring 21 at the corresponding end is compressed. When the unwinding operation is performed, the first drive motor 3 drives the driving shaft 4 to rotate periodically to realize feeding. During the feeding process, the second oil cylinder 14 drives the pressure wheel 15 to roll downward and press against the surface of the steel strip to reduce the deviation of the conveying direction of the steel strip. Since the pressure wheel 15 can buffer the lateral swing through the spring 21 when the lateral displacement occurs, the vibration occurring during the unwinding process of the steel strip can be effectively buffered. At the beginning of a feeding cycle, the third oil cylinder 17 near the edge of the first side plate 5 is contracted to reduce the clamping force of the outer part of the steel coil, thereby loosening the outer strip from the steel coil, so that the strip can be conveyed outward with the rotation; then the third oil cylinder 17 near the edge of the first side plate 5 gradually extends, and the third oil cylinder 17 near the center of the first side plate 5 begins to contract synchronously, so that the clamping force of the outer part of the steel coil is gradually restored, and the clamping force of the inner part of the steel coil is gradually reduced synchronously, so that the internal tension of the entire steel coil gradually reaches a balance, and finally the third oil cylinder 17 near the center of the first side plate 5 is contracted to resume the clamping of the steel coil. With the cooperation of the second oil cylinder 14 and the third oil cylinder 17, the strip is smoothly unwound and conveyed, and the deviation of the strip is reduced. When the strip deviates, the first oil cylinder 9 controls the pressure of the pressure roller 8 on different parts of the strip to correct the deviation; at the same time, the second oil cylinder 14 in the corresponding direction increases the pressure downward, so that the corresponding pressure wheel 15 compresses the spring 21 to the maximum limit, and the pressure wheel 15 and the pressure roller 8 apply a correction force at different positions of the strip to achieve rapid resetting of the strip.

[0017] The uncoiler provided by the utility model can effectively reduce the deviation problem in the uncoiling process of the strip steel, so that the uncoiling process can be carried out quickly and smoothly.
