[0002] Silicon steel sheet is a kind of soft magnetic alloy of ferrosilicon with extremely low carbon content, generally containing 0.5-4.5% silicon. Adding silicon can increase the resistivity and maximum magnetic permeability of iron, reduce coercive force, core loss (iron loss) and magnetic aging, and is mainly used to make iron cores of various transformers, motors and generators.

Compared with mechanical cutting, it not only reduces the stress concentration and grain damage of the section, but also can adapt to cutting at more inclination angles. When the cutting line is in the process of cutting the silicon steel sheet, the rotating frame, side frame, moving block, drive roller, fixed pressure roller and dynamic pressure roller can also be controlled to move, so as to simply realize the cutting line cutting more complex shapes on the surface of the silicon steel sheet at different angles.

[0020] 2.

The magnetic conductivity is better when the silicon steel sheet is assembled into a transformer. At the same time, the infusion pipe can pass the coolant through the infusion pipe, infusion trough, storage shell, extension shell and protective shell to cool the metal wire to the greatest extent.

[0021] 3. In the present application, the sliding frame, the first rack, the first gear and the pressing block are arranged so that the sliding frame can move back and forth on both sides of the silicon steel sheet under the drive of the micro motor. When the silicon steel sheet is being cut, the sliding frame can be moved to a suitable position first, which can not only provide good support for the silicon steel sheet, but also the pressing block can keep the silicon steel sheet in a pressed state when it is being cut, thereby effectively ensuring the stability of the silicon steel sheet during the cutting process.

[0022] In summary, through the setting of the above-mentioned structure in the present application, it is possible to cut silicon steel sheets at different angles, which not only reduces the stress concentration and grain damage of the cut surface, but also allows products with more complex shapes to be cut. At the same time, it can improve the stability of the cutting process and ensure the cut surface quality of the silicon steel sheet. BRIEF DESCRIPTION OF THE DRAWINGS

The first clearance grooves 12 correspond to the positions of the wire grooves 171, and the side frame 14 is provided with a small hole for the metal cutting wire to pass through, so that the metal cutting wire led out from the wire cutting machine can pass through the first clearance groove 12 and the small hole on the side frame 14 in turn and enter the wire groove 171. The two moving blocks 17 are fixedly installed with a storage shell 1 at the ends close to each other. 8. The storage shell 18 is provided with openings at both upper and lower ends, and the interior of the storage shell 18 is connected with the wire groove 171. An infusion groove 181 is provided in the side wall of the upper storage shell 18 close to the wire groove 171.

[0041] A storage slot 182 is provided in the side wall of the storage shell 18, and an extension shell 211 is slidably installed in the storage slot 182. A lifting plate 21 is fixedly installed at one end of the extension shell 211 away from the moving block 17. A through hole is provided in the middle of the lifting plate 21, and an electric telescopic rod is fixedly installed between it and the moving block 17, so that when the electric telescopic rod is running, the lifting plate 21 can be driven to move up and down. A protective shell 212 connected to the inside of the lifting plate 21 is fixedly installed in the middle of the side away from the moving block 17, and multiple elastic telescopic rods 22 are connected to the lifting plate 21 through a ball clamping connection around it. The ends of the multiple elastic telescopic rods 22 away from the lifting plate 21 are jointly clamped with a grinding ring 23 through a ball. When cutting, the electric telescopic rod is controlled to make the lifting plate 21 descend, ensuring that the grinding ring 23 contacts the upper surface of the silicon steel sheet. The metal cutting wire is cut at any angle and cutting shape, and the grinding ring 23 can grind the burrs generated by wire cutting on the upper surface of the silicon steel sheet.

[0042] A moving component for driving the silicon steel sheet to move is arranged on the side of the rotating groove 401 away from the rolling box 3, and the moving component includes a lifting device installed inside the shearing seat 4, and a moving roller 5 is rotatably installed on the top of the lifting device, and a driving roller 402 is arranged below the moving roller 5. The driving roller 402 is driven by a driving device installed inside the shearing seat 4. A wire rack 9 fixedly installed on the shearing seat 4 is arranged on the side of the rotating groove 401 close to the wire cutting machine, and the wire rack 9 is used to guide the cutting metal wire.

[0043] The specific working principle of the present invention is as follows: a placement rack 2 is installed at one end of the top of the base 1, and a limit plate on one side of the placement rack 2 can be freely rotated downward 90 degrees, so as to place the rolled silicon steel sheet therein, and then the silicon steel sheet is extended into the rolling box 3 from the bottom opening, passes between the fixed pressure roller 301 and the dynamic pressure roller 302, and extends from the top opening of the rolling box 3. The shear seat 4 is fixed on the top of the base 1 and contacts with the rolling box 3. The silicon steel sheet extended from the top opening of the rolling box 3 is just placed on the top of the shear seat 4. The first gear 7 is controlled to rotate by a micro motor, and the pressure block 8 and the sliding frame 6 clamp the silicon steel sheet to move. Initially, the pressure block 8 and the sliding frame 6 pass the silicon steel sheet through the rotating frame 11, and transport one end of the silicon steel sheet to between the driving roller 402 and the moving roller 5. The moving roller 5 is controlled by the lifting device and can be freely controlled to lift and lower, and cooperates with the driving roller at the bottom to achieve clamping or transportation of one end of the silicon steel sheet.

[0044] Initially, the dynamic pressure roller 302 inside the rolling box 3 is away from the fixed pressure roller 301 under the action of the electric push rod, so as to facilitate the silicon steel sheet to pass through and the sliding frame 6 to transport the silicon steel sheet. After the initial placement and clamping of the silicon steel sheet, the dynamic pressure roller 302 can be controlled to be close to the fixed pressure roller 301. The temperature of the dynamic pressure roller 302 and the fixed pressure roller 301 can be controlled. The silicon steel sheet before shearing can be hot rolled or cold rolled as needed to enhance the internal structure of the silicon steel sheet and reduce damage caused by cutting.

[0045] The movement of the silicon steel sheet is jointly controlled by the driving roller 402, the fixed pressure roller 301 and the dynamic pressure roller 302, and the position where shearing is required is transported to the middle of the rotating groove 401, and then the sliding frame 6 is controlled to move to the appropriate position by the rotation of the first gear 7, so as to prevent the sliding frame 6 from blocking the cutting of the metal cutting line while providing good support for the silicon steel sheet. The pressing block 8 is kept pressed tightly during the cutting of the silicon steel sheet, and the adjustment motor 10 installed at the bottom of the rotating groove 401 is controlled to rotate, so that the rotating frame 11, which is initially at an angle of 90 degrees with the silicon steel sheet, rotates in the required direction. The operator can adjust the rotation angle of the two side frames 14 as needed so that the cutting line is cut at a certain angle. The two moving blocks 17 can be controlled to maintain a non-vertical state so that the cutting line is tilted at a certain angle in another direction, and then the two moving blocks 17 are controlled to move together so that the metal cutting line cuts the silicon steel sheet. Compared with mechanical cutting, it not only reduces the stress concentration and grain damage of the cut surface, but also can adapt to cutting at more inclined angles. When the cutting line is in the process of cutting the silicon steel sheet, the rotating frame 11, the side frame 14, the moving block 17, the driving roller 402, the fixed pressure roller 301 and the dynamic pressure roller 302 can also be controlled to move, so as to simply realize the cutting line cutting more complex shapes on the surface of the silicon steel sheet at different angles.

[0046] When cutting, the electric telescopic rod is controlled to make the lifting plate 21 descend to ensure that the grinding ring 23 contacts the upper surface of the silicon steel sheet. The metal cutting line is cut at any angle and cutting shape. The grinding ring 23 can grind the burrs generated by the wire cutting on the upper surface of the silicon steel sheet. The infusion tube 20 is connected to the external coolant supply equipment. The coolant passes through the infusion tube 20, the infusion tank 181, the storage shell 18, the extension shell 211 and the protective shell 212 to cool the metal cutting line to the greatest extent. Similarly, the bottom moving block 17 is also designed with a grinding ring 23 that can adapt to cutting in different situations and maintain a good grinding burr effect, which greatly reduces the difficulty of subsequent grinding and improves the cross-section quality of the silicon steel sheet. The magnetic conductivity effect is better when the silicon steel sheet is assembled into a transformer.
