Description

Technical Field

[0001] This invention belongs to the field of steel manufacturing and galvanizing production technology, specifically relating to a device and method for correcting the collapse of the inner diameter of steel coils. Background Technology

[0002] In the steel manufacturing industry, steel sheets are rolled into coils, which come in two sizes: φ610 and φ508. During the rolling process, insufficient strip tension can cause the coils to not be rolled tightly, or the finished coils may be subjected to external forces during storage, causing the inner diameter of the coils to collapse and deform into an elliptical shape, making them unsuitable for further processing on the production line. This results in the entire coil of collapsed steel facing scrap, causing significant economic losses. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to provide a device and method for correcting inner diameter collapse of steel coils, thereby solving the problem in the prior art where steel coils face scrapping and result in significant economic losses when inner diameter collapse occurs.

[0004] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0005] A device for correcting the collapse of the inner diameter of a steel coil includes two sets of adjustment components. Each adjustment component includes two fixing members. The fixing members are installed on the outer edge of the steel coil. The two fixing members are connected by a connecting plate and their positions are adjustable. One end of the connecting plate is also provided with an adjustment member for fine adjustment. A traction belt tensioner is provided between the two sets of adjustment components for connection and fixation.

[0006] By adopting the above structural design, the steel coil with the correction can be fixed by the fastener, and the connection plate can be used for coarse positioning. Then, the adjustment component can be used for fine adjustment to apply force to the steel coil to complete the correction of the collapse. The corrected steel coil can then be uncoiled for a second time. Therefore, the direct economic loss caused by the direct scrapping of the collapsed steel coil is avoided.

[0007] Preferably, the fixing member is configured with an arc-shaped structure corresponding to the steel coil, and the fixing member includes a first limiting plate and a second limiting plate arranged perpendicularly to each other. The first limiting plate is fixed in contact with the surface of the steel coil, and the second limiting plate is fixed in contact with the side of the steel coil.

[0008] The above structural design allows for a high degree of fit between the correction device and the outer circumference of the steel coil. Furthermore, through multi-faceted contact, the steel coil experiences more uniform stress during the correction process, thereby improving the effect of correcting the collapse of the steel coil.

[0009] Preferably, the second limiting plate has a protrusion on its outer side, and the connecting plate has multiple adjustment holes. One end of the connecting plate is fixedly mounted on the protrusion through the adjustment hole by a screw or pin, and the other end of the connecting plate is fixedly connected to an adjustment member that is movably mounted on another fixing member.

[0010] By adopting the above structural design, the connection position of the connecting plate and the protrusion can be adjusted to accommodate steel coils of different sizes, and the correction of the steel coil can be pre-positioned or pre-adjusted, which facilitates the installation and use of the correction device.

[0011] Preferably, the adjusting component includes a connecting rod and an adjusting screw. One end of the connecting rod is connected to the connecting plate, and the other end is threaded to the adjusting screw. The adjusting screw passes through the protrusion and has an adjusting disc at its end.

[0012] With the above structural design, the distance between the screw and the connecting rod, i.e. the distance between the two fixing parts, can be adjusted by rotating the adjusting disc, thereby achieving the precision adjustment of the correction device and completing the force adjustment of the steel coil to correct internal collapse.

[0013] Preferably, the first limiting plate is also provided with a connecting ring, and the two ends of the traction belt tensioner are respectively connected and fixed to the connecting rings of the adjusting components on both sides of the steel coil.

[0014] The above structural design ensures that the two sets of adjustment components will not slip out of the steel coil when applying force to it.

[0015] Preferably, each set of adjustment components has connecting plates and adjustment components at the upper and lower positions of the two fixing parts for fixing, and the two sides of the two sets of adjustment components are respectively connected and fixed by a set of traction belt tensioners.

[0016] The present invention also provides a method for correcting the inner diameter collapse of a steel coil, which uses the above-mentioned steel coil inner diameter collapse correction device and includes the following steps:

[0017] S1. When it is necessary to correct the internal collapse of the steel coil, the steel coil to be corrected is lifted by a crane. The lifting height is just enough for the steel coil to be removed from the steel coil storage saddle, so that the weight of the steel coil can be removed.

[0018] S2. Install the inner diameter collapse correction device on both sides of the steel coil, and correct and repair the inner diameter collapse of the steel coil by adjusting the inner diameter collapse correction device.

[0019] S3. The steel coil after collapse correction and repair is placed on a fixed storage saddle by a crane. When the corrected steel coil needs to be put on the rewinding production line for secondary processing, the steel coil is installed on the uncoiler and then the steel coil correction device is removed.

[0020] Preferably, the correction method in step S2 is as follows:

[0021] S21. Assemble the adjustment component, install the two fixing parts of the adjustment component on the outer ring of the steel coil, adjust the position of the connecting plate according to the size of the steel coil, and fix one end of the connecting plate to the hole opened on the corresponding protrusion by bolts or pins to achieve pre-positioning.

[0022] S22. Fix the traction belt tensioner to the connecting ring of the adjustment assembly on both sides to prevent the correction device from falling off. Rotate the adjusting screw of the adjusting component to drive the connecting rod and connecting plate to move inward to adjust the diameter of the steel coil with precision.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] This invention discloses a device and method for correcting inner diameter collapse of steel coils. By fixing the correction device to the outside of the steel coil with inner diameter collapse, and applying pressure to the steel coil through the correction device, the collapse is corrected and repaired. The corrected steel coil is then further processed on the production line, thus avoiding the problem of scrapping caused by steel coil collapse and avoiding economic losses.
