[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 3 As shown, a silicon steel sheet shearing device for transformer production includes a conveying device 1 and a conveying device 2 5, and the conveying device 1 and the conveying device 2 5 are used to convey the silicon steel sheets;

[0021] Vertical plates 3 are arranged on both sides of the conveying device 1, and a positioning shearing assembly 4 is arranged inside the vertical plate 3. The positioning shearing assembly 4 includes two positioning blocks 8, and the two positioning blocks 8 are vertically fixed on the inner side of the vertical plate 3. A bearing inner round seat 12 is arranged on the inner side of the positioning block 8, and a bearing outer round ring 9 is movably engaged with the outer side of the bearing inner round seat 12. A shearing knife 14 is fixedly installed on the outer side of the bearing outer round ring 9 through a connecting plate. Two limit plates 10 are fixedly installed on the outer side of the bearing outer round ring 9 at symmetrical positions with respect to the shearing knife 14. A gap is arranged between the two limit plates 10, and the upper end of the positioning block 8 is movably penetrated. The limiting column 11 first places the silicon steel sheet to be sheared on the conveying device 1, and starts the four frequency conversion motors 15 through the positioning and shearing components 4, so that the rotating column 13 drives the bearing inner circle seat 12 to rotate. Since the rotating column 13 and the bearing inner circle seat 12 are eccentrically arranged, the bearing inner circle seat 12 contacts the bearing inner circle seat 12 while rotating, so that the bearing inner circle seat 12 moves up and down, and the two shearing knives 14 are closed to cut the silicon steel sheet. Each time the frequency conversion motor 15 rotates once, the two shearing knives 14 are closed once, thereby completing the positioning cutting.

[0022] In this embodiment, the limit column 11 passes through the gap between the two limit plates 10, and two limit disks 111 are fixedly installed on the outside of the limit column 11. The two limit disks 111 are respectively located at the upper and lower ends of the limit plates 10. The two limit disks 111 limit the two limit plates 10. When the inner round seat 12 of the bearing rotates, the movement of the outer ring 9 of the bearing interferes, so that the two shear knives 14 complete closed cutting.

[0023] In this embodiment, a rotating column 13 is fixedly installed inside the inner circular seat 12 of the bearing, and a variable frequency motor 15 is fixedly installed outside the vertical plate 3. One end of the output shaft of the variable frequency motor 15 is fixedly installed with one end of the rotating column 13. The rotating column 13 is eccentrically fixed to the inner circular seat 12 of the bearing, and the positioning block 8 and two limit plates 10 limit the outer circular ring 9 of the bearing.

[0024] In this embodiment, two supporting legs 6 are fixedly mounted on the lower end of the second conveying device 5 , and a material receiving assembly 7 is disposed outside the second conveying device 5 .

[0025] In this embodiment, the material receiving assembly 7 includes a receiving box 151 and a receiving box 21. A roller 16 is movably installed at the lower end of the receiving box 151. Two springs 17 are fixedly installed on one side of the receiving box 151. A magnet 18 is fixedly installed at one end of the spring 17. The magnet 18 is adsorbed on the outside of the supporting leg 6. Through the material receiving assembly 7, the magnet 18 is adsorbed on the outside of the supporting leg 6 to complete the limiting of the receiving box 151, which is convenient for material receiving. The receiving box 21 waits for material receiving at the rear of the receiving box 151 to complete uninterrupted material receiving work. The two receiving boxes are assembled by threaded rods 19 to facilitate disassembly and installation.

[0026] In this embodiment, the receiving box 1 151 and the receiving box 2 21 are threadedly connected through a threaded rod 19 and a threaded sleeve 20 .

[0027] The implementation principle of the silicon steel sheet shearing device for transformer production in the embodiment of the present application is as follows: first, the silicon steel sheet to be sheared is placed on the conveying device 1, and the four frequency conversion motors 15 are started through the positioning shearing component 4, so that the rotating column 13 drives the bearing inner circle seat 12 to rotate. Since the rotating column 13 and the bearing inner circle seat 12 are eccentrically arranged, the bearing inner circle seat 12 contacts the bearing inner circle seat 12 while rotating, so that the bearing inner circle seat 12 moves up and down, and the two shearing knives 14 are closed to cut the silicon steel sheet. Each time the frequency conversion motor 15 rotates once, the two shearing knives 14 are closed once, thereby completing the positioning cutting. Through the material receiving component 7, the magnet 18 is adsorbed on the outside of the supporting leg 6 to complete the limiting of the receiving box 1 151, which is convenient for receiving the material. The receiving box 2 21 waits for the material to be received at the rear of the receiving box 1 151, completing the uninterrupted material receiving work, and the two receiving boxes are assembled by the threaded rod 19, which is convenient for disassembly and installation.
