Description

Technical Field

[0001] This utility model belongs to the field of metallurgical shearing technology, specifically relating to a splitting shear box device based on pad compensation. Background Technology

[0002] In the metallurgical shearing field, slitting shears are used to cut long, wide steel strips into narrow strips through multiple cuts. The shearing blade consists of upper and lower blade boxes. To ensure the steel strip meets process requirements, during the shearing process, the upper blade must be aligned with the previous cut as it descends, requiring a high degree of straightness in each cut on the steel strip. Furthermore, the shearing line must be highly parallel to the direction of strip movement. Therefore, the equipment demands high precision in the shearing surfaces of the upper and lower blades. When installing new, unworn blades, it is difficult to adjust the blade gap and parallelism of the shearing surface in existing shearing blade structures. This necessitates strict requirements for the machining precision of the blades and blade boxes to meet usage requirements, resulting in high machining precision and significant limitations on installation deviations. Utility Model Content

[0003] The purpose of this invention is to provide a splitting shear box device based on pad compensation, which solves the problem that it is difficult to adjust the shear blade gap and the parallelism of the shearing surface when installing new, unworn blades in the original structure.

[0004] The technical solution adopted by this utility model is a splitting shear box device based on pad compensation, including an upper shear box and a lower shear box correspondingly provided below the upper shear box. The upper and lower shear boxes are structurally adapted to achieve shearing of wide steel strips; the upper shear box includes an adjusting shim group.

[0005] The features of this utility model also include: The upper scissor box includes an upper blade holder with an inverted L-shaped cross-section. An upper pad is fixed to the lower top surface of the upper blade holder, and an upper scissor blade is located below the upper pad. An adjusting shim set is located between the upper blade holder and the side of the upper scissor blade.

[0006] The upper scissor box also includes fasteners, which are horizontally arranged and sequentially pass through the upper blade holder, adjusting shim set and fixed to the upper scissor blade; it also includes positioning pins, which are vertically arranged and connected between the upper blade holder and the upper pad plate. The positioning pins are used to position the upper blade holder and the upper pad plate.

[0007] The upper scissor blade has an arc structure with a radius of 25,000 mm; the upper scissor box also includes a pad, which is located between the adjusting shim group and the side of the upper scissor blade.

[0008] The adjusting shim set consists of at least one shim. Different shims have different thicknesses and can be stacked to adjust the horizontal gap between the upper blade holder and the upper shear blade. The fastener is a bolt, and the upper shear blade has a threaded hole on its side that is compatible with the bolt. The upper blade holder and the upper shear blade are connected in the threaded hole by a bolt.

[0009] The lower scissor box includes a lower blade holder and a lower scissor blade. The lower blade holder is fixedly installed, and the lower scissor blade is fixedly connected to the top of the lower blade holder. The lower scissor blade has a straight structure and is used to cooperate with the upper scissor blade for cutting.

[0010] The lower and upper blade holders are aligned vertically, and the length of the lower blade matches the arc length of the upper blade to ensure effective contact between the upper and lower blades during cutting.

[0011] The beneficial effects of this utility model are: The splitting shear box device based on shim compensation provided by this utility model, by adding an adjustment shim set, allows the new shear blade to achieve the required accuracy in parallelism of the X and Y planes and shear blade gap by adjusting the thickness of the shim set during installation. This increases the allowable range of deviation during processing and installation, reduces costs, and facilitates accuracy adjustment during installation. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0015] The splitting shear box device based on pad compensation provided by this utility model, such as Figure 1 As shown, it includes an upper scissor box, and a lower scissor box is provided below the upper scissor box. The upper scissor box and the lower scissor box are structurally adapted to achieve the cutting of wide steel strips. The upper scissor box includes an adjusting shim group 3. The adjusting shim group 3 can flexibly compensate for the horizontal dimensional deviation between the upper blade holder 1 and the upper scissor blade 4 by increasing or decreasing the number of shims or replacing shims of different thicknesses, thereby reducing the machining accuracy requirements of both. At the same time, it is convenient to accurately adjust the position of the upper scissor blade 4 during on-site debugging to ensure the matching accuracy between it and the lower scissor blade 9. The upper scissor box includes an upper blade holder 1, which has an inverted L-shaped cross-section. This structure provides a stable mounting base for components such as the upper pad 5 and the upper scissor blade 4, and can withstand the longitudinal and lateral forces generated during the shearing process, preventing component displacement from affecting the shearing accuracy. The upper pad 5 is fixed to the lower top surface of the upper blade holder 1. The upper pad 5 can buffer the forces from the upper structure, reduce the direct impact between the upper blade holder 1 and the upper scissor blade 4, and at the same time provide a flat mounting reference surface for the upper scissor blade 4, ensuring the stability of the upper scissor blade 4 after installation. The upper scissor blade 4 is located below the upper pad 5, and the adjusting shim group 3 is located between the sides of the upper blade holder 1 and the upper scissor blade 4. The upper scissor box also includes a fastener 2, which is horizontally set. The fastener 2 is sequentially inserted through the upper blade holder 1, the adjusting shim group 3 and the upper scissor blade 4 and fixedly connected. It can tightly connect the upper blade holder 1, the adjusting shim group 3 and the upper scissor blade 4 into a whole, prevent the parts from loosening due to vibration during the cutting process, and ensure the stability of the cutting action. It also includes a positioning pin 6, which is set vertically and is connected between the upper blade holder 1 and the upper pad 5. The positioning pin 6 is used to position the upper blade holder 1 and the upper pad 5, and can accurately limit the relative position of the upper blade holder 1 and the upper pad 5 to avoid misalignment during installation and ensure the positional accuracy of the subsequent installation of the upper shear blade 4.

[0016] like Figure 2 As shown, the upper shear blade 4 has an arc structure with a radius of 25000mm. When this arc structure is combined with the straight structure of the lower shear blade 9, it can make the force more uniform during the shearing of the wide steel strip, reduce the burrs and deformation of the shearing surface of the steel strip, meet the process requirements of the metallurgical industry for the straightness and parallelism of the shearing of the steel strip, and meet the precise matching of the shearing surface X of the upper shear blade and the shearing surface Y of the lower shear blade. The upper scissor box also includes a pad 7, which is located between the adjusting shim group 3 and the side of the upper scissor blade 4. When the upper scissor blade 4 wears down due to long-term use, causing the shearing gap to increase, the pad 7 can be used as a supplementary adjustment component to compensate for the wear by increasing the thickness. This eliminates the need to frequently replace the upper scissor blade 4 and extends its service life. The adjusting shim group 3 consists of at least one shim. Different shims have different thickness specifications, and the shims can be stacked to adjust the horizontal gap between the upper blade holder 1 and the upper shear blade 4. Fastener 2 is a bolt. The upper shear blade 4 has a threaded hole on its side that is compatible with the bolt. The upper blade holder 1 and the upper shear blade 4 are connected in the threaded hole by a bolt. The threaded connection method is easy to disassemble and reassemble, and facilitates the replacement or adjustment of the adjustment shim group 3. At the same time, the bolt connection has strong fastening and can adapt to the dynamic load during the shearing process. The lower shear box includes a lower blade holder 8 and a lower shear blade 9. The lower blade holder 8 is fixedly installed, and its fixed installation method can ensure the stable position of the lower shear blade 9, providing a fixed shearing reference for the upper shear blade 4, and avoiding shearing position deviation caused by the displacement of the lower blade holder 8. The lower shear blade 9 is fixedly connected to the top of the lower blade holder 8. The lower shear blade 9 has a straight structure and is used to cooperate with the upper shear blade 4 for shearing. The lower blade holder 8 corresponds to the upper blade holder 1 vertically, and the length of the lower shear blade 9 matches the arc length of the upper shear blade 4 to ensure that the upper shear blade 4 and the lower shear blade 9 effectively fit together during shearing, ensuring that the wide steel strip can be fully sheared along the entire shearing length, and avoiding situations where it is not cut or sheared unevenly.
