[0002] The iron core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint on the surface.

[0032] The pressure rod 2 is driven to translate downward by the pushing mechanism 6, so that the pressure rod 2 drives the mounting frame 3 to translate downward, so that all the cutters 44 translate downward at the same time, so that all the cutters 44 can shear the corresponding iron cores, and it is also possible to cut multiple iron cores at the same time, which greatly improves the processing efficiency; in addition, due to the difference in the spacing between different iron cores, the spacing between two adjacent sliders 42 can be adjusted by the adjusting member 46, so that the cutter 44 can shear iron cores of different sizes, which greatly improves the versatility of the equipment.

[0033] Furthermore, the positioning member 45 includes an L-shaped block 451, which is fixedly connected to the top of the cutter 44, and the top of the L-shaped block 451 is slidably matched with the mounting seat 43. One side of the mounting seat 43 is slidably connected with a slide rod 452 that penetrates the side wall of the mounting seat 43, and one end of the slide rod 452 is fixedly connected with a positioning block 453 that abuts against the L-shaped block 451, and the other end of the slide rod 452 is fixedly connected with a pull block 454. The inner wall of the mounting seat 43 is provided with a mounting groove 455 that slidably matches with the positioning block 453, and a spring 456 is sleeved on the slide rod 452, one end of the spring 456 abuts against the positioning block 453, and the other end of the spring 456 abuts against the inner wall of the mounting groove 455.

[0034] When installing the cutter 44, the pull block 454 is pulled outward to make the slide bar 452 slide, so that the positioning block 453 completely slides into the installation groove 455. At this time, the spring 456 is compressed to accumulate potential energy, and then the L-shaped block 451 at the top of the cutter 44 is slidably matched with the mounting seat 43, and then the pull block 454 is released to make the slide bar 452 slide in the opposite direction, so that the positioning block 453 slides in the opposite direction to the initial position and contacts the horizontal section of the L-shaped block 451, thereby limiting the L-shaped block 45 1 is separated from the mounting seat 43, so that the mounting seat 43 and the L-shaped block 451 remain fixed; similarly, when disassembling, the pull block 454 is pulled outward to make the slide bar 452 slide, so that the positioning block 453 completely slides into the mounting groove 455, so that the positioning block 453 is separated from the L-shaped block 451 to release the restriction on the L-shaped block 451, so that the cutter 44 can be directly taken out, and the whole process can realize the rapid disassembly and assembly of the cutter 44, which is convenient for the rapid replacement of the cutter 44.

[0035] Furthermore, the adjusting member 46 includes a cylinder 461, which is fixedly connected to the outer side of the frame 1, and the output end of the cylinder 461 is fixedly connected to a movable plate 462, and the middle part of the movable plate 462 is fixedly connected to a fixed block 463, and both ends of the movable plate 462 are slidably connected to movable blocks 464, and both ends of the fixed block 463 and the movable block 464 are hinged with connecting rods 465, and one end of the two connecting rods 465 on the same fixed block 463 and the movable block 464 are respectively hinged to two adjacent sliders 42, and both ends of the movable plate 462 are provided with sliding grooves matching the movable block 464, and the movable block 464 is slidably connected to the corresponding inner wall of the sliding groove.

[0036] By controlling the cylinder 461 to translate the movable plate 462, the fixed block 463 and the movable block 464 drive the two connecting rods 465 to rotate away from each other or towards each other, so that the two adjacent sliders 42 can slide away from each other or towards each other, and the distance between the two adjacent sliders 42 can be adjusted, thereby realizing the distance between the two adjacent cutters 44, so that the cutter 44 can shear iron cores of different sizes, greatly improving the versatility of the equipment.

[0037] Further, the pushing mechanism 6 includes a connecting plate 61, one end of which is fixedly connected to the top of the pressure rod 1 2, the other end of the connecting plate 61 is fixedly connected to a vertical rod 62, the bottom end of the vertical rod 62 is fixedly connected to a connecting seat 63, the inner side of the connecting seat 63 is hinged with a second connecting rod 64, and one end of the outer side of the frame 1 is fixedly installed with a motor 65, the output shaft of the motor 65 is fixedly connected to an eccentric wheel 66, and one end of the second connecting rod 64 is rotatably connected to the outer edge of the eccentric wheel 66 through a pin. By starting the motor 65 to rotate the eccentric wheel 66, the eccentric wheel 66 drives the second connecting rod 64 to drive the vertical rod 62 to reciprocate up and down, which makes the connecting plate 61 drive the pressure rod 1 2 to slide up and down reciprocatingly, and when the pressure rod 1 2 drives the mounting frame 3 to translate downward, all the cutters 44 translate downward at the same time, which makes all the cutters 44 shear the corresponding iron cores, and it is also possible to achieve shearing work on multiple iron cores at the same time, greatly improving the processing efficiency.

[0038] Furthermore, the feeding mechanism 7 includes a guide roller 71, which is rotatably connected to one end of the bottom of the frame 1, and the top of the guide roller 71 is in contact with the iron core. One end of the guide roller 71 is fixedly connected to a gear 72, and the outer side of the frame 1 is rotatably connected to an incomplete gear 73, and the incomplete gear 73 can intermittently mesh with the gear 72 through rotation. One side of the incomplete gear 73 is coaxially fixedly connected to a pulley 1 74, and the output shaft of the motor 65 is also fixedly connected to a pulley 2 75, and the pulley 2 75 is connected to the pulley 1 74 through a belt drive. The outer side of the guide roller 71 is fixedly connected to a plurality of anti-slip strips 76, and the plurality of anti-slip strips 76 are distributed at equal angles around the guide roller 71. By starting the motor 65, the pulley 2 75 is rotated, so that the pulley 1 74 drives the incomplete gear 73 to rotate. When the incomplete gear 73 is meshed with the gear 72, the cutter 44 is translated upward and disengaged from the iron core. The gear 72 is rotated under the drive of the incomplete gear 73, which makes the guide roller 71 rotate synchronously and applies thrust to the iron core, thereby making the iron core translate to adjust the shearing position. When the incomplete gear 73 is disengaged from the gear 72, the cutter 44 is translated downward again to continue shearing the iron core. In this cycle, the iron core can automatically adjust its position, thereby realizing continuous shearing of the iron core by the cutter 44. Among them, the anti-skid strip 76 on the outside of the guide roller 71 can increase the friction between the guide roller 71 and the iron core, effectively avoiding the problem that the iron core cannot adjust its position due to slipping between the iron core and the guide roller 71.

[0039] Furthermore, a positioning mechanism 8 is provided on the bottom wall inside the frame 1, and the positioning mechanism 8 includes a plurality of mounting plates 81, which are fixedly connected to the bottom wall inside the frame 1, and the plurality of mounting plates 81 are equidistantly distributed along the length direction of the frame 1, and the inner sides of the two mounting plates 81 at both ends of the frame 1 are fixedly connected to fixed clamps 82, and the inner sides of all the mounting plates 81 in the middle of the frame 1 are provided with movable clamps 83 that cooperate with the translation of the mounting frame 3 to clamp and fix the iron core, and the outer edge of the bottom of the mounting frame 3 is fixedly connected to a plurality of pressure rods 84. The bottom of the dry pressure rod 84 is fixedly connected with a pressure block 85, and the movable clamp 83 includes a slide rod 831 that passes through the mounting plate 81. The slide rod 831 is slidably connected to the corresponding mounting plate 81, one end of the slide rod 831 is fixedly connected with a movable clamping plate 832, and the other end of the slide rod 831 is fixedly connected with a wedge block 833. The pressure block 85 can contact the wedge block 833 by moving downward. The slide rod 831 is provided with a spring 834, one end of the spring 834 contacts the wedge block 833, and the other end of the spring 834 contacts the mounting plate 81. When the mounting frame 3 translates downward, the pressure rod 84 will translate downward with the mounting frame 3 and drive the pressure block 85 to contact the corresponding wedge block 833, so that the pressure block 85 applies pressure to the wedge block 833, which makes the wedge block 833 drive the slide rod 831 to slide. At this time, the spring 834 is compressed to accumulate potential energy, so that the movable clamping plate 832 contacts and clamps the corresponding iron core, which can prevent the movable clamping plate 832 from shaking during cutting and affecting the cutting quality; when the mounting frame 3 translates upward, the pressure block 85 disengages from the wedge block 833, and the spring 834 releases the potential energy to make the slide rod 831 slide in the opposite direction, thereby making the movable clamping plate 832 disengage from the iron core, so that the iron core can move smoothly under the action of the guide roller 71 to adjust the cutting position.

[0040] Working principle: First, multiple iron cores are placed at the bottom end of the inner side of the frame 1 at equal distances, and then the motor 65 is started to rotate the eccentric wheel 66, so that the eccentric wheel 66 drives the connecting rod 2 64 to drive the vertical rod 62 to reciprocate up and down, which makes the connecting plate 61 drive the pressure rod 1 2 to slide up and down, and when the pressure rod 1 2 drives the installation frame 3 to move downward, all the cutters 44 move downward at the same time, so that all the cutters 44 cut the corresponding iron cores, and it is possible to cut multiple iron cores at the same time, which greatly improves the processing efficiency;

[0041] At the same time, when the motor 65 is started, it will drive the pulley 2 75 to rotate, so that the pulley 1 74 drives the incomplete gear 73 to rotate. When the incomplete gear 73 is meshed with the gear 72, the cutter 44 is translated upward and disengaged from the iron core. The gear 72 is rotated under the drive of the incomplete gear 73, which makes the guide roller 71 rotate synchronously and exerts a thrust on the iron core, so that the iron core is translated to adjust the shearing position. When the incomplete gear 73 is disengaged from the gear 72, the cutter 44 is translated downward again to continue shearing the iron core. In this cycle, the iron core can automatically adjust its position, thereby realizing continuous shearing of the iron core by the cutter 44, without the need for manual position adjustment, and further improving the shearing efficiency of the iron core.

[0042] When the mounting frame 3 translates downward, the pressure rod 84 will translate downward with the mounting frame 3 and drive the pressure block 85 to contact the corresponding wedge block 833, so that the pressure block 85 applies pressure to the wedge block 833, which makes the wedge block 833 drive the slide rod 831 to slide. At this time, the spring 834 is compressed to accumulate potential energy, so that the movable clamping plate 832 contacts and clamps the corresponding iron core, which can prevent the movable clamping plate 832 from shaking during cutting and affecting the cutting quality; when the mounting frame 3 translates upward, the pressure block 85 disengages from the wedge block 833, and the spring 834 releases the potential energy to make the slide rod 831 slide in the opposite direction, thereby making the movable clamping plate 832 disengage from the iron core, so that the iron core can move smoothly under the action of the guide roller 71 to adjust the cutting position.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
