Description

Technical Field

[0001] This utility model relates to the field of steel plate cutting technology, and in particular to a silicon steel plate slitting and shearing device. Background Technology

[0002] In existing technologies, silicon steel sheets often need to be slit during use. Because silicon steel sheets are relatively wide, they are often cut into multiple strips. This results in multiple slitting rollers mounted on the shearing shaft, with two sets of rollers working together to cut the silicon steel sheet. Due to the long shearing shaft, deformation occurs after a certain period of use, leading to insufficient force on the middle shearing rollers, resulting in inaccurate slitting of the silicon steel sheet and the formation of burrs. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a silicon steel sheet slitting and shearing device that can perform strip shearing on silicon steel sheets while maintaining stability during the continuous shearing process.

[0004] This utility model discloses a silicon steel sheet slitting and shearing device, including a frame, on which a first shearing shaft and a second shearing shaft are horizontally arranged at different heights. The first and second shearing shafts are rotatably connected to the frame. Several shearing wheels are spaced apart on both the first and second shearing shafts, with the shearing wheels on the first and second shearing shafts alternating. The edges of adjacent shearing wheels on the first and second shearing shafts are in contact. A power mechanism is provided at one end of the frame, with a drive gear at the output end of the power mechanism. A first gear is provided on the first shearing shaft at the same end, and a second gear is provided on the second shearing shaft.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1:

[0016] like Figures 1-5As shown, this utility model discloses a silicon steel sheet slitting and shearing device, including a frame 1. A first shearing shaft 4 and a second shearing shaft 5 are horizontally arranged at different heights on the frame 1. The first shearing shaft 4 and the second shearing shaft 5 are rotatably connected to the frame 1. A plurality of shearing wheels 6 are spaced apart on both the first shearing shaft 4 and the second shearing shaft 5. The shearing wheels 6 on the first shearing shaft 4 and the second shearing shaft 5 are alternately arranged, with the edges of adjacent shearing wheels 6 on the first shearing shaft 4 and the second shearing shaft 5 in contact. A power mechanism 19 is provided at one end of the frame 1, and a drive gear 20 is provided at the output end of the power mechanism 19. The first shearing shaft 4 and the second shearing shaft 5 are connected at different heights. A first gear 17 is mounted on shaft 4, and a second gear 18 is mounted on the second shearing shaft 5. The first gear 17 meshes with the second gear 18, and the second gear 18 meshes with the drive gear 20. An input platform 2 is mounted on one side of the frame 1, and an output platform 3 is mounted on the other side of the frame 1. A crossbeam 7 is mounted on the top of the frame 1, and one or more vertically downward pressing mechanisms are mounted on the crossbeam 7. The ends of the pressing mechanisms abut against the first shearing shaft 4 between two adjacent shearing wheels 6. One or more vertically upward supporting mechanisms are mounted on the bottom of the frame 1, and the supporting mechanisms abut against the second shearing shaft 5 between two adjacent shearing wheels 6.

[0017] A first shearing shaft 4 and a second shearing shaft 5 are rotatably mounted on the frame 1. The first shearing shaft 4 and the second shearing shaft 5 are parallel, and shearing wheels 6 are fixed at intervals on both. The shearing wheels 6 are alternately arranged, and they mesh at the alternating points to shear the silicon steel sheet. However, due to prolonged compression, the first shearing shaft 4 and the second shearing shaft 5 are prone to deformation, thus affecting the shearing effect on the silicon steel sheet. Therefore, depending on the actual situation, if the edge of the silicon steel sheet being sheared between the two shearing wheels 6 has severe burrs, a pressing mechanism can be installed at the corresponding point to press against the first shearing shaft 4, thereby increasing the shearing force between the two shearing wheels 6, ensuring stable and reliable shearing, and improving the shearing effect. A support mechanism can be installed below the second shearing shaft 5 to support the second shearing shaft 5 and ensure its stability. A first gear 17 and a second gear 18 are respectively installed at the ends of the first shearing shaft 4 and the second shearing shaft 5, and the two mesh with each other. The power mechanism 19 on the frame 1 can be an electric motor, and a drive gear 20 is installed at its output end. The drive gear 20 meshes with the second gear 18, so the power of the motor is transmitted sequentially to the first shearing shaft 4 and the second shearing shaft 5, and the power transmission is timely and stable.

[0018] The structure of the holding mechanism is as follows: a vertically downward hydraulic cylinder 8 is fixed on the crossbeam 7, located directly above the first shearing shaft 4. A connecting seat 9 is provided at the end of the telescopic rod of the hydraulic cylinder 8. The lower end of the connecting seat 9 has two mutually perpendicular arc-shaped grooves, one of which is aligned with the axial direction of the first shearing shaft 4. Two connecting shafts 10 are provided at both ends of the other arc-shaped groove, with their axial directions parallel to the axial direction of the first shearing shaft 4. Pressure rollers 11 are mounted on the connecting shafts 10, symmetrical about the vertical plane containing the central axis of the first shearing shaft 4. When the hydraulic cylinder 8 extends, the two pressure rollers 11 contact the first shearing shaft 4. The holding mechanism uses a hydraulic cylinder 8. Depending on actual needs, a hydraulic cylinder 8 can be installed above the first shearing shaft 4 between two adjacent shearing rollers 6. A connecting seat 9 is provided at the telescopic end of the hydraulic cylinder 8. Two mutually perpendicular arc-shaped grooves are provided on the connecting seat 9. One groove is designed to prevent contact interference between the connecting seat 9 and the first shearing shaft 4 when the connecting seat 9 moves downward, thus reducing wear. The other groove has a connecting shaft 10 and a pressure roller 11 mounted on the connecting seat 9 at both ends. The lowermost end of the pressure roller 11 protrudes from the connecting seat 9, so when the connecting seat 9 moves downward, the pressure roller 11 abuts against the first shearing shaft 4. During the rotation of the first shearing shaft 4, the pressure roller 11 can rotate with it, thereby reducing friction, energy consumption, and wear on the first shearing shaft 4. To ensure stable pressure on the first shearing shaft 4, the two pressure rollers 11 are located on both sides of the central axis of the first shearing shaft 4, and their positions are symmetrical. The curvature and depth of the two arc-shaped grooves on the connecting seat 9 are set according to actual needs to ensure no interference with the first shearing shaft 4 and sufficient space for assembling the pressure roller 11.

[0019] The support mechanism is structured as follows: a base plate 12 is installed at the bottom of the frame 1, and a support column 13 is installed on the base plate 12. The support column 13 is located directly below the second shearing shaft 5. A support seat 14 is installed at the upper end of the support column 13. The support seat 14 has two mutually perpendicular arc-shaped grooves, one of which is aligned with the axial direction of the second shearing shaft 5. Support shafts 15 are installed at both ends of the other arc-shaped groove, and support wheels 16 are installed on the support shafts 15. The two support wheels 16 are symmetrical about the vertical plane containing the central axis of the second shearing shaft 5 and abut against the second shearing shaft 5. The support mechanism uses a support column 13 with a support seat 14 on top. The support seat 14 also has two perpendicular arc-shaped grooves, which serve the same function as the arc-shaped grooves on the connecting seat 9 of the pressing mechanism. The support shaft 15 and support wheels 16 are located at both ends of one of the arc-shaped grooves to abut against the second shearing shaft 5 and maintain its stability.

[0020] Limiting baffles 21 are provided on both sides of the input platform 2. Several grooves 22 are provided at intervals on the input platform 2. A rotating shaft 23 is provided in the groove 22. The central axis of the rotating shaft 23 is parallel to the central axis of the first shearing shaft 4. Several conveying wheels 24 are provided at intervals on the rotating shaft 23. The uppermost end of the conveying wheel 24 is slightly higher than the upper surface of the input platform 2.

[0021] In actual processing, to ensure accurate and stable conveying of the silicon steel sheet between the first shearing shaft 4 and the second shearing shaft 5, limiting baffles 21 are installed on both sides of the input platform 2 to allow the silicon steel sheet to be input smoothly. Simultaneously, to reduce friction between the silicon steel sheet and the input platform 2 during conveying, several grooves 22 are provided on the input platform 2. Conveyor wheels 24 are mounted within these grooves via rotating shafts 23. The axial direction of the conveyor wheels 24 is perpendicular to the conveying direction, reducing the friction area between the silicon steel sheet and the input platform 2 and improving conveying stability. The uppermost point of the conveyor wheel 24 is slightly higher than the upper surface of the input platform 2, meaning the highest point of the conveyor wheel 24 protrudes 5mm from the input platform 22. This can be determined according to the actual situation.
