Description

Technical Field

[0001] This utility model relates to the field of disc shear installation technology, specifically to an edge-cutting disc shear installation structure for a pickling and rolling mill. Background Technology

[0002] A disc shearing machine uses two disc-shaped shears for cutting. Based on the different relative positions of the two shear axes and the different angles they make with the sheet metal, it is classified into straight disc shears, return disc shears, and oblique disc shears. Existing disc shear installation structures generally use multiple bolts for fixing. For example, CN215998890U discloses an edge-cutting disc shear installation structure for a pickling mill, which uses multiple screws to fix the washers on both sides of the disc shear. During installation, each screw needs to be tightened individually, reducing installation efficiency. Furthermore, the existing shear blade clearance is also very cumbersome, requiring repeated adjustments to the shear blade position, resulting in low adjustment efficiency. Utility Model Content

[0003] To address the aforementioned shortcomings, this invention provides an installation structure for a cutting disc shear in a pickling and rolling mill, which facilitates the installation and disassembly of the disc shear and also makes it easier to adjust the shear blade gap.

[0004] To achieve the above objectives, the technical solution provided by this utility model is a disc shear installation structure for a pickling and rolling mill, comprising a disc shear, wherein one end of the disc shear is provided with a first output shaft and a second output shaft, a first fixed seat is fixedly connected to the surface of the first output shaft, a first limiting rod is fixedly connected to the surface of the first fixed seat, a first clamp is also sleeved on the surface of the first output shaft, a first disc shear is disposed between the first fixed seat and the first clamp, a first fastening seat is threadedly connected to one end of the first output shaft, a second fixed seat is threadedly connected to the surface of the second output shaft, a second limiting rod is fixedly connected to the surface of the second fixed seat, a second clamp is sleeved on the surface of the second output shaft, a second disc shear is disposed between the second fixed seat and the second clamp, and a second fastening seat is threadedly connected to one end of the second output shaft.

[0005] Preferably, a locking nut is threaded onto the surface of the second output shaft and on the side of the second fixed seat near the disc shear.

[0006] Preferably, the second output shaft includes a first shaft segment and a second shaft segment, the diameter of the first shaft segment is larger than the diameter of the second shaft segment, the axes of the first shaft segment and the second shaft segment are located on the same straight line, a first threaded segment is provided on the side of the first shaft segment closer to the second shaft segment, and a second threaded segment is provided on the side of the second shaft segment away from the first shaft segment.

[0007] Preferably, the length of the first threaded section is greater than the sum of the thicknesses of the locking nut and the second fixing seat.

[0008] Preferably, the pitch of the first threaded section is 0.5-1mm.

[0009] Preferably, the surfaces of the first fastening seat and the second fastening seat are provided with fixing grooves.

[0010] Preferably, the surface of the first disc shear is provided with a limiting hole that matches the first limiting rod.

[0011] The present invention adopts the above-mentioned technical solution, and its beneficial effects include: the installation structure of the edge-cutting disc shear of the pickling and rolling mill unit has a limiting rod set on the original mounting hole position to ensure accurate installation and rotation of the disc shear. By setting a fastening seat on the surface of the output shaft, the disc shear is fixed by pressing the clamping seat with the fastening seat, which facilitates the installation and disassembly of the disc shear. It can be tightened once, which improves the efficiency of assembly and disassembly. In addition, a threaded rotatable second fixing seat is set on the surface of the second output shaft. By rotating the second fixing seat, the distance between it and the first disc shear can be adjusted, thereby facilitating the adjustment of the shear blade gap. It is simple and convenient. In addition, the locking nut further improves the stability of the second fixing seat and avoids relative rotation between the second fixing seat and the second output shaft during processing.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a disc shear installation structure for a pickling and rolling mill, including a disc shear 1. One end of the disc shear 1 is provided with a first output shaft 2 and a second output shaft 3. A first fixing seat 4 is fixedly connected to the surface of the first output shaft 2. The first fixing seat 4 can be welded and fixed to the first output shaft 2. A first limiting rod 5 is fixedly connected to the surface of the first fixing seat 4. A first clamping seat 6 is also sleeved on the surface of the first output shaft 2. A first disc shear 7 is disposed between the first fixing seat 4 and the first clamping seat 6. The surface of the first disc shear 7 is provided with a limiting hole that matches the first limiting rod 5. One end of the first output shaft 2 is threadedly connected to the first fastening seat 13. During installation, the first disc shear 7 is first inserted from one end of the first output shaft 2, and the limiting hole is aligned with the first limiting rod 5. Then, the first clamp 6 is inserted from one end of the first output shaft 2, so that one side of the first disc shear 7 is in close contact with the surface of the first fixing seat 4. The first fastening seat 13 is screwed in, so that the first fastening seat 13 is pressed against one side of the first clamp 6, thus completing the fixation of the first disc shear 7.

[0019] The surface of the second output shaft 3 is threadedly connected to a second fixed seat 8. The surface of the second fixed seat 8 is fixedly connected to a second limiting rod 9. The surface of the second output shaft 3 is fitted with a second clamping seat 10. A second disc shear 11 is provided between the second fixed seat 8 and the second clamping seat 10. The center of the surface of the first disc shear 7 and the second disc shear 11 is provided with a through hole adapted to the output shaft. The surface of the second disc shear 11 is provided with a limiting block adapted to the second limiting rod 9. One end of the second output shaft 3 is threadedly connected to a second fastening seat 14. The surface of the second output shaft 3 and the side of the second fixed seat 8 near the disc shear machine 1 is threadedly connected to a locking nut 12. The axial force between the locking nut 12 and the second fixed seat 8 increases the friction between the nut teeth of the second fixed seat 8 and the bolt teeth on the surface of the second output shaft 3, thereby preventing the second fixed seat 8 from loosening.

[0020] The second output shaft 3 includes a first shaft segment 31 and a second shaft segment 32. The diameter of the first shaft segment 31 is larger than the diameter of the second shaft segment 32. The axes of the first shaft segment 31 and the second shaft segment 32 are located on the same straight line. A first threaded segment 33 is provided on the side of the first shaft segment 31 closer to the second shaft segment 32, and a second threaded segment 34 is provided on the side of the second shaft segment 32 away from the first shaft segment 31.

[0021] The length of the first threaded section 33 is greater than the sum of the thicknesses of the locking nut 12 and the second fixed seat 8, ensuring that the second fixed seat 8 has a certain axial movement space to adjust the shear blade gap. When the shear blade gap needs to be adjusted, the second fixed seat 8 is turned so that it moves in the axial direction of the second output shaft 3. A feeler gauge is placed between the first disc shear 7 and the second disc shear 11, with the second disc shear 11 pressed against one side of the second fixed seat 8. The axial movement of the second fixed seat 8 during rotation pushes the second disc shear 11 to move synchronously with the second fixed seat 8 until the surface of the first disc shear 7 touches the feeler gauge. The gap between the first disc shear 7 and the second disc shear 11 is the thickness of the feeler gauge. Then, the locking nut 12 is used to fix the second fixed seat 8. Finally, the second fastening seat 14 is used to fix the second disc shear 11.

[0022] The pitch of the first thread segment 33 is 0.5-1mm. The smaller pitch setting makes it easier to adjust the spacing.

[0023] The surfaces of the first fastening seat 13 and the second fastening seat 14 are provided with fixing grooves 15, which facilitate the tightening of the fastening seats. When the first fastening seat 13 and the second fastening seat 14 are tightened, the first output shaft 2 and the second output shaft 3 are locked, preventing the output shafts from rotating when the fastening seats are tightened.
