Description

Technical Field

[0001] This invention relates to the field of transformer core technology, specifically to a transformer core production apparatus. Background Technology

[0002] The transformer core is the core component of the transformer's magnetic circuit and one of the most critical parts of the transformer. Its function is to conduct and concentrate the magnetic flux generated by electromagnetic induction, realizing the energy conversion between the primary and secondary windings of electrical energy and magnetic energy. The material, structure, and processing precision of the core directly determine the transformer's core performance such as no-load loss, operating noise, and excitation characteristics. The core is a closed magnetic circuit structure and is mostly made of multiple layers of thin silicon steel sheets stacked together, which requires a stacking device to stack them layer by layer.

[0003] Existing stacking devices typically use mechanical chucks to place silicon steel sheets on a base and stack them layer by layer. However, during the stacking process, misalignment may occur between each layer of silicon steel sheets. If it cannot be corrected in time, the misalignment will continue to accumulate as the number of stacked layers increases, eventually causing the misalignment of the entire core to exceed the standard, resulting in irregular magnetic circuits, increased magnetic flux leakage, and potentially causing problems such as increased core vibration and excessive operating noise.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing press core production equipment. Summary of the Invention

[0011] Preferably, the bottom of the first and second straightening blocks are both fixedly connected to a first rack inside the stacking platform, the bottom of the first and second abutting plates are both fixedly connected to a second rack inside the stacking platform, and a gear is rotatably connected between the first and second racks inside the stacking platform, with the tooth surfaces of the first and second racks meshing with the gear tooth surfaces.

[0012] Preferably, two sets of the first abutting blocks are arranged opposite each other in the inner groove of the second correcting block, and the abutting surfaces of the two sets of first abutting blocks are set with an inclined structure, and the pushing block abuts against the abutting surfaces of the first abutting blocks.

The adjustment component inside the second straightening block includes a limiting plate disposed on the outside of the second straightening block. Limiting blocks are fixedly connected to the upper and lower ends of the limiting plate on the side away from the silicon steel sheet.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention comprises a moving block, a first rotating disk, a second rotating disk, a first correcting block, a first abutting plate, and an abutting assembly. A drive motor rotates the first rotating disk. Since the bottom of the moving block is simultaneously embedded in the arc-shaped groove of the first rotating disk and the straight groove of the second rotating disk, the moving block moves away from the left and right sides of the top of the stacking platform along the grooves. In conjunction with a first rack, a second rack, and a gear, the first correcting block and the first abutting plate move synchronously towards the side of the silicon steel sheet to clamp it, correcting the silicon steel sheet in the left-right direction. Simultaneously, the movement of the first correcting block drives the abutting assembly to correct the silicon steel sheet in the front-back direction. This effectively eliminates the lateral and longitudinal misalignment problems of manual stacking or traditional stacking devices, ensuring a regular magnetic circuit in the iron core and improving the iron core production qualification rate. 2. This invention includes a limiting plate, a limiting block, an adjusting plate, a first oil tank, a first piston rod, a second abutting block, a second oil tank, and a second piston rod. During the stacking process, as the number of silicon steel sheets increases, the difficulty of correction in the middle increases. At this time, the stacking platform will be continuously lowered under pressure, and the second piston rod will further contract, delivering more oil to the first oil tank. The extension of the first piston rod is dynamically adjusted, thereby pushing the adjusting plate to squeeze the first spring. The first spring will increase the pushing force on the limiting plate, realizing the adaptive adjustment of the limiting plate's abutting force on the side of the silicon steel sheets according to the stacking height of the silicon steel sheets. This effectively corrects silicon steel sheets of different heights. The limiting block restricts the movement range of the adjusting plate to prevent over-correction and damage to the silicon steel sheets. Attached Figure Description

[0033] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0034] Please see Figures 1-13 The present invention provides a technical solution: a transformer core production device, including a device base 1, a stacking platform 2 is provided in the middle area of ​​the top of the device base 1, a third spring is fixedly connected to the bottom of the stacking platform 2, the other end of the third spring is fixedly connected to the inside of the device base 1, storage platforms 3 are installed on both sides of the stacking platform 2 at the top of the device base 1, a moving platform 4 is installed above the device base 1 by a support rod, an adsorption plate 5 is installed inside the moving platform 4 by a moving module, silicon steel sheets 6 are stacked on both the stacking platform 2 and the storage platform 3, and a straightening mechanism is installed on the top of the stacking platform 2;

[0035] The silicon steel sheets 6 to be stacked are placed on the storage platform 3. The moving module inside the moving platform 4 is activated to drive the adsorption plate 5 to move above the storage platform 3. The adsorption plate 5 descends and activates the vacuum adsorption function to accurately adsorb a single silicon steel sheet 6. Then the moving module drives the adsorption plate 5 to move directly above the stacking platform 2. The adsorption plate 5 descends and places the silicon steel sheet 6 in the preset stacking position of the stacking platform 2. This process is repeated to complete the stacking.

[0036] The correction mechanism includes a movable block 71 that slides within grooves on the left and right sides of the top of the stacking platform 2. A first rotating disk 72 is rotatably connected to the center of the stacking platform 2. A second rotating disk 73 is fixedly connected to the inner wall of the stacking platform 2 above the first rotating disk 72. The bottom of the movable block 71 extends into the grooves formed on the surfaces of the first rotating disk 72 and the second rotating disk 73. The grooves on the surface of the first rotating disk 72 are arc-shaped and are driven by a drive motor installed inside the device base 1. The grooves on the surface of the second rotating disk 73 are straight grooves. The bottom of the movable block 71 is located between the first rotating disk 72 and the second rotating disk 73. 73 The sliding is limited within the surface groove. A first straightening block 74 is fixedly connected to the outside of the moving block 71. A first abutting plate 77 is provided on the periphery of the silicon steel sheet 6 corresponding to the position of the first straightening block 74. A first rack 8 is fixedly connected to the bottom of the first straightening block 74 inside the stacking platform 2. A second rack 9 is fixedly connected to the bottom of the first abutting plate 77 inside the stacking platform 2. A gear 10 is rotatably connected between the first rack 8 and the second rack 9 inside the stacking platform 2. The tooth surfaces of the first rack 8 and the second rack 9 mesh with the tooth surfaces of the gear 10. Abutting components are provided on the front and rear sides of the moving block 71. An adjustment component is provided inside the first straightening block 74.

[0037] The drive motor drives the first rotating disk 72 to rotate. Since the bottom of the moving block 71 is simultaneously embedded in the arc-shaped groove of the first rotating disk 72 and the straight groove of the second rotating disk 73, the rotational motion of the first rotating disk 72 is converted into the relative sliding of the moving block 71 along the left and right sides of the top of the stacking platform 2. This causes the first straightening block 74 on its outer side to move closer to the side of the silicon steel sheet 6. When the first straightening block 74 moves, the first rack 8 at its bottom drives the gear 10 to rotate. The rotation of the gear 10 drives the second rack 9 to move. The movement of the second rack 9 causes the first contact plate 77 to fit against the outer side of the silicon steel sheet 6 to achieve left and right direction correction.

[0038] As one embodiment of the present invention, the abutment component includes a second correction block 781 that is limited and slidable in the sliding grooves on the front and rear sides of the top of the stacking platform 2. A first abutment block 782 is fixedly connected in the inner groove of the second correction block 781. A push block 783 is fixedly connected in the inner side of the moving block 71. A second abutment plate 784 is provided on the periphery of the silicon steel sheet 6 corresponding to the position of the second correction block 781. Two sets of first abutment blocks 782 are arranged opposite each other in the inner groove of the second correction block 781. The abutment surfaces of the two sets of first abutment blocks 782 are set with an inclined structure. The push block 783 abuts against the abutment surfaces of the first abutment blocks 782. A first rack 8 is fixedly connected to the bottom of the second correction block 781 inside the stacking platform 2. A second rack 9 is fixedly connected to the bottom of the second abutment plate 784 inside the stacking platform 2. A gear 10 is rotatably connected between the first rack 8 and the second rack 9 inside the stacking platform 2. The tooth surfaces of the first rack 8 and the second rack 9 mesh with the tooth surfaces of the gear 10.

[0039] As the moving block 71 slides outward, the pushing block 783 on the inner side of the moving block 71 moves synchronously and comes into contact with the inclined contact surface of the first abutting block 782 in the inner groove of the second straightening block 781. As the pushing block 783 continues to advance, the guiding effect of the inclined surface pushes the second straightening block 781 along the front and rear sliding grooves on the top of the stacking platform 2 toward the front and rear sides of the silicon steel sheet 6. When the second straightening block 781 moves, the first rack 8 at the bottom of the second straightening block 781 also drives the gear 10 to rotate, driving the second abutting plate 784 to fit against the front and rear outer sides of the silicon steel sheet 6, thereby achieving correction in the front and rear directions.

[0040] In one embodiment of the present invention, the adjustment assembly includes a limiting plate 791 disposed outside the first straightening block 74. Limiting blocks 792 are fixedly connected to the upper and lower ends of the limiting plate 791 on the side away from the silicon steel sheet 6. The limiting blocks 792 extend into the interior of the first straightening block 74. A first spring is fixedly connected to the inner side of the limiting plate 791, and an adjusting plate 793 is fixedly connected to the other end of the first spring. A first oil tank 794 is fixedly connected to the inner wall of the first straightening block 74 on the side away from the limiting plate 791. A first piston rod 795 is slidably limited at the upper and lower ends within the first oil tank 794. The output of the first piston rod 795... The device base 1 is fixedly connected to a second contact block 796. A second spring is sleeved on the surface of the first piston rod 795. A second oil tank 797 is installed inside the device base 1 below the stacking platform 2. A second piston rod 798 is slidably limited inside the second oil tank 797. The output end of the second piston rod 798 is fixedly connected to the bottom of the stacking platform 2. The middle oil chamber of the first oil tank 794 is connected to the oil chamber below the second oil tank 797 through a hose. The limiting block 792 is set as an "L" shaped structure. The adjusting plate 793 is set as a "U" shaped structure. The contact surface of the second contact block 796 is set as an inclined structure.

[0041] The stacking platform 2 moves downward, pushing the second piston rod 798 to retract into the second oil tank 797, squeezing the oil inside the second oil tank 797 and conveying it to the first oil tank 794 through the hose. This, in turn, pushes the first piston rod 795 to move up and down on both sides of the first oil tank 794. The movement of the first piston rod 795 pushes the second abutment block 796 to move. Since the abutment surface of the second abutment block 796 has an inclined structure, the movement of the second abutment block 796 will push the adjusting plate 793 to move outward. The outward movement of the adjusting plate 793 will compress the first spring, which will increase the pushing force on the limiting plate 791 and increase the contact force between the limiting plate 791 and the side of the silicon steel sheet 6.

[0042] As an embodiment of the present invention, adjustment components are provided inside both the first correction block 74 and the second correction block 781, and the抵触力度 (it should be noted that "抵触力度" may be an incorrect expression here, perhaps it should be "contact force") can be adjusted synchronously. Two correction mechanisms are symmetrically arranged between the silicon steel sheets 6 to perform all-round correction on the "day"-shaped iron core. The adjustment component inside the second correction block 781 includes a limiting plate 791 arranged on the outer side of the second correction block 781. The upper and lower ends of the side of the limiting plate 791 away from the silicon steel sheet 6 are fixedly connected with limiting blocks 792, and the limiting blocks 792 extend into the second correction block 781. The inner side of the limiting plate 791 is fixedly connected with a first spring, and the other end of the first spring is fixedly connected with an adjustment plate 793. On the inner wall of the second correction block 781 on the side away from the limiting plate 791, a first oil tank 794 is fixedly connected. The upper and lower ends of the first oil tank 794 are limited and slide with a first piston rod 795. The output end of the first piston rod 795 is fixedly connected with a second contact block 796. The surface of the first piston rod 795 is sleeved with a second spring. The second correction block 781 is horizontally limited and slides on the top of the stacking table 2. Each group of the first oil tank 794 and the second oil tank 797 and their pipelines are symmetrically arranged.

[0043] Working principle: When using this transformer iron core production device, first stack the silicon steel sheets 6 to be stacked on the storage table 3. Start the moving module inside the moving table 4 to drive the adsorption plate 5 to move above the storage table 3. The adsorption plate 5 descends and starts the vacuum adsorption function to accurately adsorb a single silicon steel sheet 6. Then the moving module drives the adsorption plate 5 to move directly above the stacking table 2, and the adsorption plate 5 descends to place the silicon steel sheet 6 at the preset stacking position on the stacking table 2. Repeat this process to complete the stacking. Then start the driving motor to drive the first rotating disk 72 to rotate. Since the bottom of the moving block 71 is simultaneously embedded in the arc-shaped chute of the first rotating disk 72 and the straight groove of the second rotating disk 73, the rotational movement of the first rotating disk 72 is converted into the relative sliding of the moving block 71 along the left and right side chutes on the top of the stacking table 2, driving the first correction block 74 on its outer side to approach the side of the silicon steel sheet 6. When the first correction block 74 moves, the first rack 8 at its bottom drives the gear 10 to rotate, and the rotation of the gear 10 drives the second rack 9 to move. The movement of the second rack 9 drives the first contact plate 77 to fit against the outer side of the silicon steel sheet 6 to achieve left and right direction correction. While the moving block 71 slides outward, the pushing block 783 inside the moving block 71 moves synchronously and contacts the inclined contact surface of the first contact block 782 in the inner groove of the second correction block 781. As the pushing block 783 continues to advance, using the guiding effect of the inclined surface, it pushes the second correction block 781 to approach the front and back sides of the silicon steel sheet 6 along the front and back side chutes on the top of the stacking table 2. When the second correction block 781 moves, the first rack 8 at the bottom of the second correction block 781 also drives the gear 10 to rotate, driving the second contact plate 784 to fit against the front and back outer sides of the silicon steel sheet 6 to achieve front and back direction correction.

[0044] After stacking is completed, the stacking platform 2 moves downward under pressure. The downward movement of the stacking platform 2 pushes the second piston rod 798 to retract into the second oil tank 797, squeezing the oil inside the second oil tank 797 and conveying it to the first oil tank 794 through the hose. This, in turn, pushes the first piston rod 795 to move up and down to both sides of the first oil tank 794. The movement of the first piston rod 795 pushes the second abutment block 796 to move. Since the abutment surface of the second abutment block 796 has an inclined structure, the movement of the second abutment block 796 will push the adjusting plate 793 to move outward. The outward movement of the adjusting plate 793 will compress the first spring, which will increase the pushing force of the first spring on the limiting plate 791 and increase the abutment force of the limiting plate 791 on the side of the silicon steel sheet 6, so as to realize adaptive adjustment according to the stacking height. At the same time, the limiting block 792 restricts the movement range of the adjusting plate 793 to prevent over-correction and damage to the silicon steel sheet 6.

The upper and lower ends of the limiting plate (791) away from the silicon steel sheet (6) are fixedly connected to limiting blocks (792). The limiting blocks (792) extend into the interior of the second correction block (781). The inner side of the limiting plate (791) is fixedly connected to a first... A spring, with an adjusting plate (793) fixedly connected to the other end of the first spring, and a first oil tank (794) fixedly connected to the inner wall of the second correction block (781) on the side away from the limiting plate (791). A first piston rod (795) is slidably limited at both ends inside the first oil tank (794). A second abutment block (796) is fixedly connected to the output end of the first piston rod (795). A second spring is sleeved on the surface of the first piston rod (795). The second correction block (781) is slidably limited at the top of the stacking platform (2).
