Through the combination of knives, full-cycle shearing of silicon steel sheets and separate shearing of part of the sheet can be achieved.

[0028] As an embodiment, to adjust the angle of the bevel blade 3, a rotating shaft 5 is provided on the base 1. The tool holder 4, on which the bevel blade 3 is mounted, is fixed to the rotating shaft 5. The rotating shaft 5 is rotated and engaged with the base 1 to adjust the angle of the bevel blade 3. Specifically, the lower end of the rotating shaft 5 is cylindrical, which is rotated and engaged within the base 1. The upper end of the rotating shaft 5 is columnar, which facilitates the fixation of the tool holder 4 on the rotating shaft 5, and the bevel blade 3 is mounted on the tool holder 4.

[0029] As an embodiment, in order to achieve precise adjustment of the angle of the bevel knife 3, a positioning disk 7 is provided on the base 1. The positioning disk 7 is located below the conveying channel 2. At the same time, at least two positioning holes 8 are provided on the positioning disk 7. The connecting line of the centers of the positioning holes 8 is an arc, and the center of the arc is on the same vertical line as the axis of the rotating shaft 5. A positioning member 6 is provided at the lower end of the tool holder 4, and the tool holder 4 is precisely positioned by using the positioning member 6 to be stuck in the positioning hole 8. Specifically, there are scales at the positions of the positioning disk 7 corresponding to the positioning holes 8. When the positioning member 6 is stuck in the corresponding positioning hole 8, the included angle between the tool holder 4 and the width direction of the conveying channel 2 can be ensured. Specifically, the upper end size of the positioning member 6 is larger than the lower end size of the positioning member 6. The upper end of the positioning member 6 is a cuboid, and the lower end of the positioning member 6 is a cylinder (not shown in the figure). The lower end of the positioning member 6 is stuck in the positioning hole 8.

[0030] As an embodiment, in order to determine the 0-degree reference of the bevel knife 3, a limiting block 9 is provided on the positioning disk 7. At the same time, the positioning member 6 is provided on the outer side surface of the tool holder 4 far from the rotating shaft 5. When the outer side surface of the positioning member 6 abuts against the outer side surface of the limiting block 9, the bevel knife 3 is parallel to the width direction of the conveying channel 2.

[0031] As an embodiment, the bevel knives 3 are respectively located on the left and right sides of the limiting block 9, and the limiting block 9 serves as the 0-degree reference for both bevel knives 3 at the same time.

[0032] As an embodiment, in order to facilitate the rotation of the tool holder 4, a support wheel 10 is provided at the bottom of the tool holder 4. The support wheel 10 is in rolling fit with the positioning disk 4, so that the rotation of the tool holder 4 on the positioning disk 7 can be assisted, and the rotation of the tool holder 4 is more relaxed and the adjustment is convenient. Specifically, the support wheel 10 is provided at one end of the tool holder 4 far from the rotating shaft 5.

[0033] As an embodiment, in order to reduce the weight of the tool holder 4, the tool holder 4 and the rotating shaft 5 form a "C" - shaped structure with the opening facing downwards. The side surface of the tool holder 4 is a support column 12.

[0034] As an embodiment, in order to facilitate the positioning member 6 to disengage from and be stuck in the positioning hole 8, a first sliding sleeve 11 is provided on the support column 12 of the tool holder 4. The positioning member 6 is provided on the outer side surface of the first sliding sleeve 11. The first sliding sleeve 11 slides up and down in cooperation with the support column 12, so that the positioning member 6 also moves up and down accordingly. Specifically, in order to prevent the first sliding sleeve 11 from rotating circumferentially, the cross-sectional shape of the support column 12 is rectangular. Specifically, in order to strengthen the strength of the tool holder 4, it further includes a reinforcing rod 13. One end of the reinforcing rod 13 is fixed on the support column 12, and the other end of the reinforcing rod 13 is fixed on the rotating shaft 5. Specifically, a second sliding sleeve is provided on the rotating shaft 5, and both ends of the reinforcing rod 13 are respectively fixed on the first sliding sleeve 11 and the second sliding sleeve, so that it does not affect the up and down movement of the positioning member 6 and can strengthen the strength of the tool holder 4. Specifically, the reinforcing rod 13 abuts against the positioning disk 7 in the free state.

[0035] The transformer core includes an upper iron yoke ①, a lower iron yoke ②, a core side column and a core side column ⑤. The core side column includes a left core side column ③ and a right core side column ④. Figure 3 and 5 .

[0036] Example 1

[0037] When the cross-sectional area of ​​the core limb and the iron yoke is equal, the angled joint between the upper iron yoke ① and the lower iron yoke ② and the left core limb ③ is 45 degrees. Figure 3 There are three kinds of knife arrangement schemes to choose from: V knife 14, round knife 15 and oblique knife 3. Figure 4 .

[0038] Example 2

[0039] When the cross-sectional areas of the core limb and the iron yoke are not equal, in order to avoid a large gap between the core limb and the iron yoke and reduce losses, the joint angles of the core limb and the upper iron yoke ① and the lower iron yoke ② are both 35° to 38°. Specifically, the joint angles can be selected from 35°, 36°, 37° and 38°. Figure 5 , so it is necessary to adjust the angles of the two oblique knives 3 respectively. The V knife 14, the round knife 15 and the oblique knife 3 require three knife arrangement schemes to achieve shearing, such as Figure 6 .

[0040] Specifically, the principle of the present invention is to use the rotating shaft 5 to drive the tool holder 4 to rotate, that is, to rotate the bevel knife 3, so as to realize the angle adjustment of the bevel knife 3. At the same time, a positioning plate 7 and a positioning member 6 are provided, and the positioning member 6 is clamped in the positioning hole 8 of the positioning plate 7 to realize the precise positioning of the bevel knife 3. The high accuracy of the angle adjustment makes the production efficiency high.

[0041] Working Principle: Silicon steel sheet coils first enter the loading system, which supports, retracts, and unloads the raw material. Once unwound, the silicon steel sheet enters the feeding system, which is responsible for conveying the sheet and coordinating with the various systems. The shearing system, the core component of the equipment, is responsible for cutting the silicon steel sheet into specific shapes. The shearing system consists of three mechanisms: a V-blade 14, a circular blade 15, and three oblique blades. This combination of blades enables full-cycle shearing of the silicon steel sheet and individual shearing of sections of the sheet.

[0042] Specifically, when the cross-sectional areas of the core limbs and the yoke are equal, the joint angle between the core limbs and the yoke is 45°. When the cross-sectional areas of the core limbs and the yoke are unequal, the joint angle between the core limbs and the yoke is also 45°. No other angle exists, so it is not possible to set up a multi-angle rotating structure to achieve precise positioning. The angle adjustment of the bevel knife 3 in the prior art is only 0° and 45°, with a small angle adjustment range and low precision. However, one bevel knife 3 of the present technical solution can accurately position at five angles: 0°, 35°, 36°, 37°, and 38°, and the other bevel knife 3 can accurately position at five angles: 0°, -35°, -36°, -37°, and -38°.

[0043] Based on the above scheme, if various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
