Description

Technical Field

[0001] The present invention relates to the technical field of shearing equipment, and in particular to a steel shearing equipment and method. Background Art

[0002] Thin steel shearing equipment is a crucial tool in the metalworking industry, specifically designed for shearing thin-gauge steel. This type of equipment typically offers a high degree of precision and flexibility to accommodate the shearing needs of thin steel of varying thicknesses, widths, and lengths. Thin steel shearing equipment plays a vital role in various fields, including metallurgy, construction, automotive manufacturing, and home appliance manufacturing. By utilizing advanced blade materials and shearing technologies, these devices achieve efficient and precise shearing while ensuring the flatness and smoothness of the sheared surface.

[0003] In the prior art, there is a shearing device for producing silicon iron core steel sheets, such as the publication number CN218903757U. When in use, the reduction motor drives the transmission roller to rotate to conduct the silicon iron core steel sheets, and the rotating roller further guides them. The anti-slip sheet on the rotating roller can prevent sliding during transmission, meeting the actual use requirements and further improving the user experience, and the actual use effect is good.

[0004] However, in actual use, although the problem of poor guiding effect of the existing shearing device during use is solved, in the actual shearing process, the sheared steel segment is pushed forward by the continuously moving steel belt at the rear. At this time, it may not only cause congestion in the unloading of steel segments at the discharge end, but also easily lead to friction of the cut of the sheared steel segment, and easily cause the contact between the rear steel belt and the sheared steel segment, resulting in the deflection of the steel belt.

[0005] Therefore, the present invention proposes a steel shearing device and method to solve the problem that the steel segments cut by the existing equipment are pushed forward by the continuously moving steel belt at the rear, which may not only cause congestion in the unloading of the steel segments at the discharge end, but also easily lead to friction of the cuts of the sheared steel segments. The shearing structure and the unloading structure can be cleverly combined to enable the steel belt to be sheared while simultaneously meeting the auxiliary unloading of the sheared steel segments in front, thereby avoiding affecting the stable movement of the steel belt at the rear.

The arc-shaped groove 221 is adapted to the position of the arc-shaped ear plate 211, and the arc-shaped ear plate 211 and the arc-shaped groove 221 are movably connected through the pin; the inner sides of one end of the fixed upper clamping seat 21 and the movable lower clamping seat 22 are respectively fixedly connected with a protruding block 1 212 and a protruding block 222, the protruding block 1 212 is integrally formed with the fixed upper clamping seat 21, the protruding block 222 is integrally formed with the movable lower clamping seat 22, and the inner side of the protruding block 222 is fixedly connected with the fixed upper clamping seat 21. A rotating shaft 223 is rotatably connected to the wall; a reserved groove 210 is provided on the horizontal surface of the fixed upper clamping seat 21 near the protruding block 1 212, and the inner surface of the reserved groove 210 is rotatably connected to a swing arm plate 24, and the swing arm plate 24 is connected to the protruding block 1 212 through a shaft.

The other end of the arc-shaped support bracket 254 is movably connected to the outer surfaces of both ends of the material removal roller 255; In this embodiment, if Figure 3-Figure 6 As shown, by controlling the extension and retraction of the electric telescopic rod 23, the movable lower clamping seat 22 is moved up and down according to the cooperation between the arc-shaped ear plate 211, the arc-shaped slot 221 and the pin shaft, and a structure similar to a clamp is formed between the fixed upper clamping seat 21 and the movable lower clamping seat 22. Figure 8-Figure 9As shown, when the protruding block 222 is separated from the protruding block 1 212, the front ends of the fixed upper clamping seat 21 and the movable lower clamping seat 22 are brought together, and the connection between the movable rod 1 251 and the movable rod 2 252 is coordinated, and the swing arm plate 24 drives the cutter 242 to swing downward, so that the cutter 242 performs a shearing operation on the steel strip. At the same time, the angle between the movable rod 1 251 and the movable rod 2 252 changes, driving the arc-shaped support 254 to swing. Once the electric telescopic rod 23 retracts, the tail end of the movable lower clamping seat 22 is tilted upward, so that the protruding block 1 212 contacts the protruding block 2 222. Figure 10-11 As shown, the cutter 242 swings upward, and the material removal roller 255 moves upward at this time, so that after the steel strip is cut, the cut steel segment is automatically removed and pushed to the side of the steel segment discharge rack 14, eliminating the manual operation steps of the staff.

[0023] Example 3, refer to the attached Figure 1-16 The second embodiment further includes a plurality of guide assemblies 240 and 2403 on the inner side of the swing arm plate 24, wherein the guide assemblies include a connecting wing block 240, a guide inclined rod 2401 and an arc-shaped top support plate 2404. The upper end of the arc-shaped top support plate 2404 is fixedly connected to the inner surface of the swing arm plate 24, and the other end of the arc-shaped top support plate 2404 is fixedly connected to the upper surface of the fixed upper clamping seat 21; the connecting wing block 240 is fixedly installed on the two side surfaces of the swing arm plate 24, the outer surface of the guide inclined rod 2401 is movably connected to the inner surface of the connecting wing block 240, and the lower end of the guide inclined rod 2401 is fixedly connected to the horizontal plane of the fixed upper clamping seat 21; the outer surface of the guide inclined rod 2401 is movably sleeved with a spring 1 2402 and a spring 2 2403. The lower end of the spring 1 2402 is fixedly connected to the surface of the fixed upper clamping seat 21, and the other end of the spring 1 2402 is fixedly connected to the upper surface of the fixed upper clamping seat 21. The lower surface of the connecting wing block 240 is fixedly connected, the lower end of the spring 2403 is fixedly connected to the upper surface of the connecting wing block 240, and the other end of the spring 2403 is fixedly connected to the inner surface of the upper end of the guide oblique rod 2401. It is worth noting that the cross-section of the guide oblique rod 2401 is a "T"-shaped structure, which can limit the range of movement of the spring 2403 to avoid it from falling out from the end; the reason why the guide components are installed on both sides and the inner side of the swing arm plate 24 is to ensure the guidance of the swing arm plate 24 when driving the cutter 242 to perform shearing operations, and to meet the buffering requirements of the cutter 242 when performing shearing operations. The cooperation of the spring 1 2402, the spring 2403 and the arc-shaped top support plate 2404 can weaken the jitter of the cutter 242 during the up and down movement and shearing operation, ensure that the shear cut is smoother, avoid the occurrence of sawtooth or burrs, and can further extend the overall service life of the cutter 242.

[0024] Example 4, refer to the attached Figure 1-16, on the basis of embodiment three, in order to achieve smooth contact between the outside of the material picking roller 255 and the bottom of the sheared steel section, this embodiment further proposes: the material picking roller 255 is a hollow cylindrical structure, and a micro-blower 2551 is provided on the outer surface of one end of the material picking roller 255, and the input end of the micro-blower 2551 is connected with an air duct 2552, and the air duct 2552 extends into the cavity of the material picking roller 255; the auxiliary contact component includes a contact roller 256, and the contact roller 256 is fixedly connected to the outer surface of the material picking roller 255 by bolts. The contact roller 256 is an annular plate structure, and an installation groove 2560 and an embedding groove 2561 are respectively provided on the inner wall of the contact roller 256, and a strip groove adapted to the embedding groove 2561 is provided on the inner wall of the material picking roller 255, and a ball 25601 is rotatably connected to the inner surface of the mounting groove 2560, and a dust collecting part is provided inside the embedding groove 2561; In this embodiment, the strip groove opened on the inner wall of the material-removing roller 255 is adapted to the embedded groove 2561 to form a circulation channel with the inner cavity of the material-removing roller 255. When the micro-blower 2551 is started, the air duct 2552 draws air, so that the air around the contact roller 256 enters the inner cavity of the material-removing roller 255 through the embedded strip frame 2562; it is worth noting that the mounting groove 2560 here is used to install the ball 25601. By adding the ball 25601, it is ensured that the contact roller 256 is in contact with the surface of the steel section. The friction is reduced, thereby reducing the resistance when the steel section is picked; and it should be noted that the outward extension length of the embedded strip frame 2562 installed in the embedded groove 2561 is shorter than the extension length of the ball 25601. Such a design will not cause the ball 25601 to contact with the steel section, and will not cause the input port of the introduction hole 2565 to be blocked. It should be noted that the model of the micro fan 2551 here can be: 45W micro induced draft fan CY100 heat dissipation duct exhaust fan 220V small volume single-phase centrifugal fan.

[0025] Example 5, refer to the attached Figure 1-16 , on the basis of embodiment 4, in order to assist in collecting the debris and dust around the contact roller 256, this embodiment further proposes: the dust collecting part includes an embedded bar frame 2562, and the two ends of the embedded bar frame 2562 are fixedly connected with connecting ear plates 25621, the embedded bar frame 2562 and the contact roller 256 are fixedly connected by the connecting ear plates 25621, the embedded bar frame 2562 passes through the installation groove 2560 and the inner wall of the bar groove and extends to the inner cavity of the material picking roller 255, the outer surface of the embedded bar frame 2562 is provided with a cover plate 2563, and the other side surface of the embedded bar frame 2562 is provided with a filter plate 2564, the inner wall of the cover plate 2563 is provided with an inlet hole 2565, and the inner surface of the inlet hole 2565 is correspondingly provided with a conical bucket 2566, the lower end of the conical bucket 2566 is provided with an opening, and the outer surface of the conical bucket 2566 is fixedly provided with an adsorption brush 2567; In this embodiment, when the contact roller 256 contacts the surface of the steel section, the micro fan 2551 is always kept in the open state. At this time, the micro fan 2551 draws external air into the interior of the embedded bar frame 2562, and the debris enters the interior of the conical bucket 2566 through the inlet hole 2565. The reason why the conical bucket 2566 is designed to be narrowed inward is to increase the flow rate of air entering, and the conical bucket 2566 on the inner bottom surface of the cover plate 2563 and the conical bucket 2566 on the inner top surface of the filter plate 2564 are designed to be opposite and staggered, which can improve the The debris entering the inner cavity of the embedded bar frame 2562 adheres to the adsorption brush 2567, and the adsorption brush 2567 enhances the ability to capture debris. The debris is retained by the adsorption brush 2567, and the filter plate 2564 blocks the debris and impurities, while the air is discharged through the output end of the micro fan 2551. If the collected debris and impurities need to be cleaned, it is only necessary to separate the embedded bar frame 2562 as a whole from the contact roller 256. It should be noted that the size of the embedded bar frame 2562 can be adjusted and replaced according to the actual dust collection capacity.

[0026] Example 6, refer to the attached Figure 1-16 On the basis of the fifth embodiment, the present invention further provides a method for steel shearing equipment, comprising the following steps: Step 1: First, place the thin steel strip to be cut on the conveyor belt 13 for transportation, and pre-set the conveyor belt 13 to ensure the intermittent movement of the thin steel strip, and the amplitude of the thin steel strip driven by the conveyor belt 13 matches the extension and retraction time of the electric telescopic rod 23; Step 2: Control the electric telescopic rod 23 to extend and retract. According to the coordination between the arc-shaped ear plate 211, the arc-shaped slot 221 and the pin shaft, the movable lower clamping seat 22 moves up and down, and the front ends of the fixed upper clamping seat 21 and the movable lower clamping seat 22 are brought together. At this time, the swing arm plate 24 drives the cutter 242 to swing downward, so that the cutter 242 cuts the steel strip. Once the electric telescopic rod 23 retracts, the tail end of the movable lower clamping seat 22 tilts upward, causing the cutter 242 to swing upward. At this time, the auxiliary contact component is triggered, realizing the forward pushing of the intermittently cut steel segment and the automatic removal of the cut steel segment. Step 3: During the linkage of the auxiliary contact components, the micro fan 2551 is controlled to always remain in the on state. At this time, the micro fan 2551 draws external air into the interior of the embedded bar frame 2562; Step 4: The debris enters the interior of the conical bucket 2566 through the inlet hole 2565, is retained by the adsorption brush 2567, and the filter plate 2564 blocks the debris and impurities, while the air is discharged through the output end of the micro fan 2551. If the collected debris and impurities need to be cleaned, it is only necessary to separate the embedded bar frame 2562 as a whole from the contact roller 256.
