[0018] In order to make the content of the present utility model more clearly understood, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0019] Combined with the attached Figure 1 - attached Figure 2 , a silicon steel sheet cutting device for oil-immersed transformer processing, including a machine table 1, on which there are an installation seat 2 and a movable seat 3. On the installation seat 2 and the movable seat 3, there are respectively a left silicon steel sheet placement table 4 and a right silicon steel sheet placement table 5. On the left side of the left silicon steel sheet placement table 4 and the right side of the right silicon steel sheet placement table 5, there are first inclined surfaces, and a lower knife 6 is installed on the first inclined surfaces. At the rear ends of the installation seat 2 and the movable seat 3, there are installation frames 7, and on the two installation frames 7, there are respectively a left lifting plate 8 and a right lifting plate 9 that can be lifted. On the right side of the left lifting plate 8 and the left side of the right lifting plate 9, there are second inclined surfaces, and a stamping upper knife 10 corresponding to the position of the lower knife 6 is provided on the second inclined surfaces.

[0020] In one embodiment, on the right side of the machine table 1, there is an installation plate 11. A sliding column 12 is connected between the installation plate 11 and the installation seat 2, and the movable seat 3 is slidably arranged on the sliding column. A transmission lead screw 13 that is in threaded connection with the movable seat 3 is rotatably provided between the installation plate 11 and the installation seat 2, and the transmission lead screw 13 is driven by a transmission motor 14 arranged outside the installation plate 11. In this embodiment, the installation plate 11 is ingeniously designed on the right side of the machine table 1. It is not only the fixed foundation of the entire adjustment system but also provides a stable and smooth sliding track for the movable seat 3 through the sliding column 12. As the core transmission component, the precision thread design of the transmission lead screw 13 ensures that the movable seat 3 can accurately and smoothly move along the sliding column 12 under the drive of the transmission motor 14. This design not only simplifies the adjustment process of the silicon steel sheet length but also greatly improves the adjustment accuracy and efficiency, enabling the device to easily meet the cutting requirements of silicon steel sheets of different sizes.

[0021] In one embodiment, guide cylinders 15 are provided on both sides of the mounting brackets 7. Guide columns 16 that slide through the guide cylinders 15 on the same side are provided at the upper ends of the left lifting plate 8 and the right lifting plate 9. A pressing plate 17 is connected to the upper ends of the guide columns 16 on the same side, and a spring 18 sleeved on the guide column 16 is connected between the pressing plate 17 and the upper end of the guide cylinder 15. A motor fixing plate 22 is also provided on both sides of the mounting brackets 7. A driving motor 19 is mounted on the side of the motor fixing plate 22. A cam 20 is provided on the output shaft of the driving motor 19, and the curved edge of the cam 20 contacts the upper surface of the pressing plate 17. The lifting plate driving mechanism in this embodiment relies on the coordinated action of the guide cylinders 15, guide columns 16, pressing plate 17 and spring 18 on both sides of the mounting brackets 7. The driving motor 19 converts the rotational motion into the up-and-down reciprocating motion of the pressing plate 17 through the cam 20, and then drives the left lifting plate 8 and the right lifting plate 9 to lift and lower synchronously. The introduction of the spring 18 not only effectively alleviates the impact during the lifting process, but also ensures the smoothness and reliability of the lifting action. In addition, the motor fixing plate 22, as a stable mounting platform for the driving motor 19, ensures the stable transmission of the driving force and further improves the overall working performance.

[0022] In one embodiment, the lower knife 6 and the stamping upper knife 10 are respectively detachably mounted on the first inclined surface and the second inclined surface through locking screws. This design greatly improves the flexibility and maintenance convenience of the equipment. When the tool wears or needs to be replaced to adapt to different cutting requirements, the operator can quickly and easily complete the disassembly and installation of the tool without complex tools or cumbersome steps. At the same time, the detachable design also helps to reduce the downtime and improve the production efficiency.

[0023] In one embodiment, a U-shaped support plate 21 is further provided on the machine table 1 between the mounting seat 2 and the movable seat 3. The U-shaped support plate 21 plays a certain supporting role for the long strip-shaped silicon steel sheet.

[0024] Working principle: First, the two ends of the long strip-shaped silicon steel sheet to be cut are respectively placed on the left silicon steel sheet placing table 4 and the right silicon steel sheet placing table 5. Subsequently, the driving motor 19 on both sides of the mounting brackets 7 is started, and the driving motor 19 drives the cam 20 to rotate. During the rotation of the cam 20, its convex top contacts the upper surface of the pressing plate 17, thereby generating a downward pressure. At this time, the spring 18 is in a compressed state, and this pressure is transmitted to the left lifting plate 8 and the right lifting plate 9 through the guide column 16, causing the two to move downward synchronously.

[0025] As the left lifting plate 8 and the right lifting plate 9 descend, they respectively drive the stamping upper knife 10 mounted thereon to move along their respective second inclined surfaces until they form corresponding positions with the lower knife 6 below. At this time, the stamping upper knife 10 and the lower knife 6 cooperate to perform synchronous stamping and cutting on both sides of the silicon steel sheet to form the bevels required for processing.

[0026] The driving motor 19 continues to drive the cam 20 to rotate. When the convex top of the cam 20 disengages from the contact with the pressure plate 17, the pressure plate 17 and the guide post 16 start to rise under the elastic force of the spring 18. This rising action drives the left lifting plate 8, the right lifting plate 9, and the stamping upper knife 10 to reset, that is, to move upward back to the initial position.

[0027] After completing one cutting action, if it is necessary to cut silicon steel sheets of different lengths, the driving motor 14 can be operated to drive the transmission lead screw 13 to rotate. The transmission lead screw 13 is threadedly connected to the movable seat 3. Therefore, its rotation will drive the movable seat 3 to slide on the sliding column 12, thereby adjusting the distance between the left silicon steel sheet placement table 4 and the right silicon steel sheet placement table 5 to adapt to silicon steel sheets of different lengths.

[0028] In addition, both the lower knife 6 and the stamping upper knife 10 are designed to be detachably installed on their respective first inclined surfaces and second inclined surfaces through locking screws. This design facilitates quick disassembly and installation when the tool needs to be replaced or maintained. At the same time, a U-shaped support plate 21 is also provided on the machine table 1 between the mounting seat 2 and the movable seat 3 to provide additional structural support and enhance the overall stability and safety of the equipment.

[0029] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the creation of the present utility model, design structurally similar ways and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
