Description

Technical Field

[0001] This utility model relates to the technical field of steel plate processing equipment, specifically a thin steel plate shearing device. Background Technology

[0002] Thin steel sheet is a type of steel with a thickness between 0.2 mm and 4 mm. Due to its light weight, high strength, and ease of processing and forming, it is widely used in construction, automotive, home appliance, and machinery manufacturing industries. In construction, thin steel sheet is used to make roofs, walls, and other enclosure structures, offering corrosion resistance, aesthetic appeal, and convenient construction. In automotive manufacturing, it is a primary material for car bodies, reducing weight and improving fuel economy. In the home appliance industry, thin steel sheet is used to make outer shells, inner liner, and other components, making products sturdy and durable. Furthermore, thin steel sheets have good weldability and paintability, facilitating subsequent processing. With technological advancements, the performance of thin steel sheets continues to improve to meet the needs of more fields. However, at present, thin steel sheets have significant shortcomings during processing and cutting, easily leading to slippage and displacement. Slight deviations are tolerable, but larger slippage can cause serious errors. Once a large error occurs, at best, the raw materials cannot be used, resulting in resource waste; at worst, the product must be scrapped and re-produced, which not only increases costs but also affects production efficiency. Therefore, solving the slippage and displacement problem in the processing and cutting of thin steel sheets is urgent. Existing technologies may already have solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a thin steel plate shearing device, comprising: a device base, a device ceiling, and a pair of mounting flanges, wherein the pair of mounting flanges are respectively installed on the device ceiling, a steel plate bearing and adjusting structure is installed on the device base, and a symmetrical pressure clamping structure is installed on the device ceiling, wherein the symmetrical pressure clamping structure comprises: an electric telescopic rod, a covering drive housing, a blade drive motor, a cutting blade, a pair of electric slide rails, and a pair of adjusting and pressurizing components;

[0004] The electric telescopic rod is installed on the ceiling of the device, the covering drive housing is installed on the electric telescopic rod, the blade drive motor is installed inside the covering drive housing, the cutting blade is installed on the blade drive motor via a rotating shaft, a pair of electric slide rails are respectively installed on the ceiling of the device, and a pair of adjusting and pressurizing components are respectively installed on a pair of electric slide rails;

[0005] The adjustment and pressurization assembly includes: an electric slider, a hydraulic fixed push rod, a spring bearing plate, several pressing auxiliary springs, and a pressing inclined block.

[0006] The electric slider is mounted on the electric slide rail, the hydraulic retaining push rod is mounted on the electric slider, the spring bearing plate is mounted on the hydraulic retaining push rod, and a plurality of the pressing auxiliary springs are respectively mounted on the spring bearing plate, and the plurality of the pressing auxiliary springs are respectively connected to the fitting pressing inclined block;

[0007] It should be noted that, as described above, the device ceiling is properly fixed to the ceiling via a pair of mounting flanges. The thin steel plate to be cut is placed on the steel plate bearing and adjusting structure on the device base. A pair of electric sliders on a pair of electric slide rails are driven to move to the appropriate position. Then, the hydraulic locking push rods are simultaneously extended and retracted, causing multiple pressing auxiliary springs on a pair of spring bearing plates to tightly press the pressing wedges against the surface of the thin steel plate. Because the pressing wedges are sloped, the thin steel plate is subjected to a mutual pushing force at the cutting point, while the steel plate below... The load-bearing adjustment structure applies an equal outward pulling force, which secures the thin steel plate between the two. Then, the electric telescopic rod extends and drives the blade drive motor inside the drive housing, causing the cutting blade to rotate and cut the thin steel plate below. The shock absorber on the device base makes the entire cutting process more stable and less prone to shaking. The protective rubber pad on the bonding and pressing wedge provides greater adhesion when it contacts the thin steel plate, further preventing slippage.

[0008] Preferably, the steel plate bearing and adjustment structure includes: a module guide slide rail, a displacement support platform, a secondary support platform, a displacement power motor, a rotating shaft support block, a displacement threaded rod, and a pair of plate under-support pads.

[0009] The module guide rail is installed on the device base, the secondary support platform is movably installed on the module guide rail, and the secondary support platform is fitted onto the displacement threaded rod. The displacement support platform is installed on the device base, and the device base is connected to the secondary support platform. The displacement power motor is installed inside the displacement support platform. The rotating shaft support block is installed on the device base, and the rotating shaft support block is connected to the displacement threaded rod. The displacement threaded rod is connected to the displacement power motor. A pair of underplate support pads are respectively installed on the displacement support platform and the secondary support platform.

[0010] It should be noted that, as described above, the parameters of the entire device can be adjusted through the control panel set on the displacement support platform. First, the displacement power motor inside the displacement support platform is driven to rotate, which in turn causes the displacement threaded rod to rotate along the rotating shaft support block and drive the secondary support platform to slide on the module guide rail to a suitable position. Then, the thin steel plate is placed on a pair of under-plate support pads, and a pair of fitting and pressing inclined blocks are pressed on the surface of the thin steel plate. At this time, the displacement threaded rod is slightly driven to rotate, so that the secondary support platform moves slightly closer to the rotating shaft support block side, and the thin steel plate is properly fixed.

[0011] Preferably, the displacement support platform is provided with a maintenance and inspection port;

[0012] Preferably, a shock absorber is provided on the base of the device;

[0013] Preferably, a protective rubber pad is provided on the bonding and pressing inclined block;

[0014] Preferably, a control panel is provided on the displacement support platform. Beneficial effects

[0015] This utility model provides a thin steel plate shearing device. It offers the following advantages compared to existing technologies: This thin steel plate shearing device employs a symmetrical pressure clamping structure, which tightly adheres the thin steel plate to the surfaces of a pair of under-plate support pads. Simultaneously, in conjunction with a steel plate bearing and adjustment structure, each side of the thin steel plate is subjected to a pair of forces in slightly opposite directions. Under the action of these two forces, the thin steel plate is fully fixed. This unique design fundamentally eliminates the possibility of displacement of the thin steel plate during the fixing process, effectively improving processing accuracy and providing a reliable guarantee for the precise processing of thin steel plates.

Figure 1-3As shown, a thin steel plate shearing device includes: a device base 1, a device ceiling 2, and a pair of mounting flanges 3.

On rod 4, the blade drive motor 6 is installed inside the covered drive housing 5, the cutting blade 7 is mounted on the blade drive motor 6 via a rotating shaft, a pair of electric slide rails 8 are respectively mounted on the device ceiling 2, and a pair of adjusting and pressurizing components are respectively mounted on the pair of electric slide rails 8; the adjusting and pressurizing components include: an electric slider 9, a hydraulic fixing push rod 10, a spring bearing plate 11, several pressing auxiliary springs 12, and a pressing inclined block 13; the electric slider 9 is mounted on the electric slide rail 8, and the hydraulic fixing push rod 10 is mounted on the electric slider 9. The spring-bearing support plate 11 is mounted on the hydraulic fixing push rod 10, and a plurality of the pressing auxiliary springs 12 are respectively mounted on the spring-bearing support plate 11, and the plurality of the pressing auxiliary springs 12 are respectively connected to the fitting pressing inclined block 13; the steel plate bearing adjustment structure includes: a module guide slide rail 14, a displacement support platform 15, a secondary support platform 16, a displacement power motor 17, a rotating shaft support block 18, a displacement threaded rod 19, and a pair of under-plate support pads 20; the module guide slide rail 14 is mounted on the device base 1, and the secondary support platform 16 is movably mounted on the module guide slide rail 10. The secondary support platform 16 is mounted on the guide rail 14 and the displacement threaded rod 19. The displacement support platform 15 is mounted on the device base 1 and the device base 1 is connected to the secondary support platform 16. The displacement power motor 17 is mounted inside the displacement support platform 15.

A pair of underplate support pads 20 are respectively mounted on the displacement support platform 15 and the secondary support platform 16.

[0023] According to the appendix Figure 1-3It is concluded that, through a pair of mounting flanges 3, the device ceiling 2 is properly fixed to the ceiling. The thin steel plate to be cut is placed on the steel plate bearing and adjusting structure on the device base 1. The pair of electric sliders 9 on the pair of electric slide rails 8 are driven to move to the appropriate position. Then, the hydraulic fixing push rod 10 is synchronously extended and retracted, so that multiple pressing auxiliary springs 12 on the pair of spring bearing plates 11 press the pressing inclined block 13 tightly against the surface of the thin steel plate. Because the pressing inclined block 13 is a slope structure, the thin steel plate is in a state of mutual pushing force at the cutting point, while the steel plate bearing and adjusting structure below applies an equal outward pulling force. At this time, the thin steel plate is properly fixed between the two. Then, the electric telescopic rod 4 is driven to extend, and the blade drive motor 6 inside the drive housing 5 is driven, so that the cutting blade 7 rotates to cut the thin steel plate below.

The control panel installed on the displacement support platform 15 allows the parameters of the entire device to be adjusted. First, the displacement power motor 17 inside the displacement support platform 15 is driven to rotate, which causes the displacement threaded rod 19 to rotate on the rotating shaft support block 18 and drive the secondary support platform 16 to slide on the module guide rail 14 to a suitable position. Then, the thin steel plate is placed on a pair of under-plate support pads 20, and a pair of bonding and pressing wedge blocks 13 are pressed on the surface of the thin steel plate. At this time, the displacement threaded rod 19 is slightly driven to rotate, so that the secondary support platform 16 moves slightly closer to the rotating shaft support block 18, and the thin steel plate is properly fixed.
