[0034] This application provides a galvanized sheet shearing device that solves the technical problems of warped edges and burrs on the sheared part of the galvanized sheet.

[0035] See Figure 1 The diagram shown illustrates the structure of the galvanized sheet shearing device. Figure 2 The diagram shows the structure of the base and the fixing plate. Figure 3 The schematic diagram of the fastener structure shown and Figure 4The diagram shows the disassembled structure of the fixing component. This utility model provides a galvanized sheet shearing device, including a base 2, a shearing table 3, a shearing blade 4, and a fixing component 5 disposed on the base 2.

[0036] See Figure 1 and Figure 2 In some embodiments, the upper surface of the base is provided with bolt holes, and the shearing table is fixed to the base by bolts. The shearing table on the base provides stable support for the galvanized sheet, preventing it from sagging or deforming due to its own weight or shearing force, thus ensuring shearing accuracy. The shearing table also serves as a protective layer for the base, preventing the base from being directly subjected to wear or damage from the shearing tools, thereby extending the equipment's lifespan.

[0037] In some embodiments, the shearing blade 4 is positioned above the shearing table 3. The shearing blade is supported by cemented carbide or high-strength steel and has a sharp cutting edge. Upon contact with the galvanized sheet, the shearing blade applies a large shearing force, cutting it into two parts. The cut galvanized sheet exits the shearing blade from the side furthest from the feed end, i.e., it is discharged.

[0038] The number of fixing members 5 is two; the two fixing members 5 are respectively located on both sides of the shearing position of the shearing blade 4, and are movably arranged above the shearing table 3, and can move downward to press the galvanized sheet tightly on the shearing table 3.

[0039] See Figure 1 and Figure 3 The two fixing members are located on either side of the shearing position of the shearing blade, one on the feed side and the other on the discharge side relative to the shearing blade. When shearing is required, the fixing members move downwards to contact the galvanized sheet, pressing the galvanized sheet firmly onto the shearing table. Furthermore, the two fixing members have a relatively narrow gap, which neither interferes with the downward cutting of the shearing blade nor deviates too much from the shearing position, ensuring uniform stress on the galvanized sheet.

[0040] The fixed component contains a power mechanism, which drives the downward movement. The power mechanism can take many forms, such as hydraulic cylinder drive or electric motor drive, and is not specifically limited to any particular type.

[0041] The aforementioned utility model provides a galvanized sheet shearing device. Fixing members are located on both sides of the shearing position of the shearing blade. When the galvanized sheet is placed at the shearing position, the fixing members can move downwards to press the galvanized sheet firmly onto the shearing table, preventing the galvanized sheet from sliding during shearing and avoiding uneven friction between the shearing blade and the galvanized sheet, thus helping to reduce burr formation. Simultaneously, under the action of the fixing members, the galvanized sheet is evenly pressed during shearing, ensuring the stability of both sides and effectively preventing edge warping due to uneven pressure during shearing, reducing damage to the galvanized sheet after shearing.

[0042] See Figure 3 and Figure 4 In some embodiments, the fixing member 5 includes two vertical sliding components 31, a first fixing plate 32, a first hydraulic cylinder 33, and a first guide post 34.

[0043] Each vertical sliding component 31 includes a first guide rail bracket 41, a first groove 42, and a first sliding block 43. The first guide rail bracket 41 is fixed on the base 2. The first groove 42 is located on the first guide rail bracket 41 and is arranged vertically relative to the base 2. The two first sliding blocks 43 respectively cooperate with the corresponding first groove 42 and are connected to the first fixing plate 32.

[0044] The first hydraulic cylinder 33 is disposed above one of the first guide rail brackets 41 and is connected to the corresponding first sliding block 43 through the first guide post 34.

[0045] This type of fastener features a simple design and convenient operation. A first hydraulic cylinder provides uniform and adjustable pressure, ensuring the galvanized sheet does not move or deform during shearing, thus guaranteeing neat edges and precise dimensions. The adjustable pressure also accommodates shearing requirements for galvanized sheets of varying thicknesses. The first hydraulic cylinder enables rapid clamping and continuous operation, making it suitable for mass production and improving efficiency.

[0046] In some specific embodiments, the lower end of the first guide rail bracket is fixed to the base by bolts. A first groove is formed inside the first guide rail bracket, and the first groove is vertically positioned relative to the base. Two first sliding blocks are respectively welded to both ends of the first fixed plate, forming an integral structure. The two first sliding blocks slide in their corresponding mating first grooves. A first guide post is connected to one end of each first sliding block. The first guide post runs in the same direction as the first fixed plate. The first hydraulic cylinder is positioned above the first guide rail bracket containing the first guide post. The lower end of the first hydraulic cylinder is bolted to the upper end of the first guide rail bracket.

[0047] During use, for example, the galvanized sheet is placed on the shearing table. To avoid warping and burrs during shearing, the first hydraulic cylinder is activated first to push the first guide post to move, which in turn drives the first sliding block and the first fixing plate to move together inside the first groove. This causes the fixing parts to move closer to and press against both sides of the shearing position of the galvanized sheet, ensuring that the shearing plate is stably in the shearing area. The shearing blade then begins to shear the galvanized sheet, thereby reducing the formation of warping and burrs.

[0048] In some embodiments, the two vertical sliding components can be linked, either activating the two first hydraulic cylinders simultaneously or activating them separately. For example, simultaneously activating the first hydraulic cylinders on the two fixing members maintains the same pressure, simultaneously pushing the first guide posts on the two fixing members to move, and causing the first sliding block and the first fixing plate to move as a whole within the first groove. This ensures that the positions and running directions of the two first fixing plates are aligned, allowing them to press the galvanized sheet with the same pressure and speed upon contact.

[0049] See Figure 4 To prevent the galvanized sheet from shifting due to sliding during the shearing process, in some embodiments, the lower surface of the first fixing plate 32 faces the galvanized sheet, and a rubber plate 51 and a rubber pad 52 of matching size are provided on the lower surface of the first fixing plate 32; wherein, the rubber plate 51 is located between the first fixing plate 32 and the rubber pad 52. The rubber plate is fixed to the lower surface of the first fixing plate by bolts to increase friction. To further alleviate the impact force of the rubber plate contacting the surface of the galvanized sheet, a rubber pad is attached to the working position of the rubber plate. Due to its excellent elasticity, it can further absorb the impact force, so that the galvanized sheet receives less impact force when it is pressed. Furthermore, because the rubber pad has a high coefficient of friction, it can effectively prevent the galvanized sheet from sliding or scratching during pressing or shearing. In addition, the rubber pad can prevent direct friction between the rubber plate and the galvanized sheet, extending the service life of the rubber plate. Under the fixing action of the fasteners, the galvanized sheet is more stably positioned in the shearing area, thereby reducing the generation of burrs and edge warping. Meanwhile, the rubber pad is in direct contact with the galvanized sheet, which not only ensures that the force is evenly distributed on both sides of the shearing position of the galvanized sheet, but also avoids friction or damage to the surface of the galvanized sheet, thus ensuring the quality of the galvanized sheet after shearing.

[0050] See Figure 4 In some embodiments, the two first sliding blocks 43 are located at both ends of the first fixed plate 32, forming an integral structure.

[0051] For example, the two first sliding blocks and the first fixed plate are integrally formed. The integrated structure allows the first fixed plate to move stably in the first groove along with the first sliding block, and the first fixed part is always in a horizontal state during sliding, so as to achieve uniform stress on the galvanized sheet during the shearing process.

[0052] In some embodiments, the two fasteners 5 are axially symmetrically distributed along the shearing direction, which ensures uniform force distribution on the galvanized sheet during shearing, preventing displacement or deformation caused by uneven force distribution on one side. This also helps balance the shearing force, reducing vibration during equipment operation and improving the stability of the shearing process. Furthermore, it firmly clamps the galvanized sheet, preventing slippage or misalignment during shearing, ensuring the straightness and precision of the sheared edge, reducing burrs and deformation at the sheared edge, and improving shearing quality. In addition, uniform force distribution reduces fatigue damage to equipment components, lowers the probability of failure, and thus extends the overall service life of the equipment.

[0053] To remove burrs from the galvanized sheet after shearing, in some embodiments, the galvanized sheet shearing device 1 further includes a grinding mechanism 6, such as... Figure 5 As shown. Figure 5 This is a schematic diagram of the grinding mechanism in the galvanized sheet shearing device of this utility model. The grinding mechanism 6 includes a grinding component 11 and a moving component 21. The moving component 21 is connected to the base 2, located on the discharge side of the fixed component 5, and reciprocates along the shearing direction of the shearing blade 4. The grinding component 11 is connected to the moving component 21 and is used to grind the galvanized sheet after shearing.

[0054] For a detailed description of the location of the moving parts, see [link to relevant documentation]. Figure 1 and Figure 5 In some embodiments, the moving component 21 includes a guide rail plate 22, a guide rail groove 23, a moving block 24, a telescopic column 25, a fixing plate 26, and a hydraulic cylinder 27.

[0055] The lower surface of the guide rail plate 22 is connected to the base 2, and the upper surface of the guide rail plate 22 has a guide rail groove 23. The moving block 24 moves along the guide rail groove 23. One end of the telescopic column 25 is connected to the moving block 24, and the other end is connected to the hydraulic cylinder 27. The hydraulic cylinder 27 is connected to the side of the base 2 through the fixing plate 26 and is close to the discharge side. The abrasive part 11 is arranged above the moving block 24.

[0056] See Figure 1 and Figure 2 In some embodiments, the lower surface of the guide rail plate is connected to the base; a base groove is provided on the base, and the guide rail plate is adapted to the base groove, so that the guide rail plate is placed in the base groove and connected to the top of the base; at the same time, a fixing plate is provided on the side of the base and is close to the base groove.

[0057] In addition Figure 5A guide rail groove is provided on the upper surface of the guide rail plate, and the moving block is placed in the guide rail groove. A hole adapted to the diameter of the hydraulic cylinder is provided on the fixed plate. One end of the telescopic column is connected to the moving block, and the other end passes through the hole on the fixed plate and is then connected to the hydraulic cylinder. The hydraulic cylinder is fixed to the fixed plate with bolts. Then, the fixed plate is fixed to the side of the base and close to the discharge side. The abrasive part is provided above the moving block.

[0058] For a detailed description of the frosted parts, see [link to relevant documentation]. Figure 6 , Figure 6 This is a schematic diagram of the moving part and the abrasive part in the galvanized sheet shearing device of this utility model. The abrasive part 11 includes a first abrasive plate 12, a second abrasive plate 13, and a connecting member 14; the first abrasive plate 12 is located on the upper surface of the moving block 24, and the second abrasive plate 13 is located on the lower surface of the connecting member 14, and is disposed opposite to the first abrasive plate 12; wherein, the connecting member 14 is disposed above the moving block 24.

[0059] In some embodiments, the abrasive part is mainly used to remove burrs from the sheared part of the galvanized sheet. For example, if the lower surface of the sheared galvanized sheet is placed on the first abrasive plate, the upper surface of the sheared galvanized sheet will contact the second abrasive plate, thereby removing burrs from both the upper and lower surfaces of the galvanized sheet at the same time.

[0060] In some embodiments, the connector 14 includes an adjusting plate 61, a guide rod 62, and an adjusting bolt 63. The second frosted plate 13 is located on the lower surface of the adjusting plate 61. The adjusting plate 61 is connected to a first directional block 71 and a second directional block 72 at both ends. It is connected to the moving block 24 through the guide rod 62 and the adjusting bolt 63, so that the vertical distance between the adjusting plate 61 and the moving block 24 can be adjusted to accommodate galvanized sheets of different sizes.

[0061] In addition, the two ends of the movable block 24 also have a support block 81 and an adjusting block 82; the support block 81 is connected to the first directional block 71 through the guide rod 62; the adjusting block 82 is connected to the second directional block 72 through the adjusting bolt 63.

[0062] To clearly describe how the sanding mechanism cuts the burrs off the galvanized sheet, see [link to relevant documentation]. Figure 1 , Figure 5 and Figure 6First, the lower surface of the sheared galvanized sheet is placed in the working position of the first abrasive plate. The adjusting bolt is rotated, further moving the adjusting plate up and down. The height of the adjusting plate is adjusted according to the thickness of the galvanized sheet so that the second abrasive plate is close to the upper surface of the sheared galvanized sheet. The adjusting bolt is then tightened within the adjusting block. The guide rod ensures the stability of the first and second abrasive plates during operation, preventing displacement. Next, the hydraulic cylinder is activated, moving the telescopic column, which in turn moves the moving block within the guide rail groove. This causes the first and second abrasive plates to grind the sheared edge of the galvanized sheet, removing burrs.

[0063] In some embodiments, both the first and second abrasive plates have coarse, medium, and fine grit sizes. In actual use, a suitable grit size abrasive plate can be selected according to the size of the burrs to achieve burr removal and smoothness of the sheared area of ​​the galvanized sheet.

[0064] The aforementioned utility model provides a galvanized sheet shearing device. By setting fixing plates on both sides of the shearing position, the galvanized sheet is fixed, preventing the shearing plate from moving or deforming during the shearing process. This ensures neat sheared edges and accurate dimensions, reduces burr formation, decreases subsequent grinding or finishing work, and improves work efficiency and safety. Simultaneously, it reduces galvanized sheet waste and damage to the galvanized layer. This utility model's design, with its fixing components, ensures uniform and stable force on the galvanized sheet during shearing, reducing burr formation and solving the technical problem of warped edges and burrs on the sheared part of the galvanized sheet.
