Description

Technical Field

[0001] The present invention relates to the technical field of transformer core processing, and particularly to a stacking and flipping method and system for transformer core processing. Background Art

[0002] A transformer core mainly consists of a core and coils wound thereon to form a complete electromagnetic induction system, and is the main magnetic path part in a transformer. The magnitude of the power transmitted by the transformer depends on the material and cross-sectional area of the core. There are various types of cores during production, such as rectangular, annular, E-shaped, and U-shaped. During the stacking process of the core, regardless of the type of transformer core, it needs to go through processes such as silicon steel sheet shearing, lamination assembly, clamping and fixing, flipping operation, transportation, and general assembly. In the prior art, the lamination assembly, clamping and fixing, and flipping operation of the transformer core are usually completed on the same working station. The flipping of the core relies relatively heavily on lifting equipment, which requires a large number of lifting components to be installed on the lamination station, resulting in a large investment in the overhead traveling crane. Moreover, there are certain safety hazards for the workers working on the lamination station. Additionally, the lamination and flipping processes can only be carried out separately in sequence, and the stacking operation needs to be paused during flipping, leading to a high idle rate of the equipment and poor flexibility, restricting the improvement of production capacity. Summary of the Invention

[0003] To solve the problems existing in the lamination process and flipping process of the above-mentioned transformer core, the present invention provides a stacking and flipping method and system for transformer core processing.

[0004] The technical solution of the present invention is as follows:

[0016] In order to push the main turning platform and the auxiliary turning platform more evenly and stably, the main telescopic cylinder and the auxiliary telescopic cylinder are arranged at intervals along the width direction of the support base, and the output ends are hinged to the midline position of the bottom surface of the main turning platform and the auxiliary turning platform respectively.

[0017] In order to facilitate the swinging of the telescopic cylinder as the main turning platform and the auxiliary turning platform rotate, the end surfaces of the main support part and the auxiliary support part facing away from each other are vertically provided with a plurality of rotation grooves. The cylinder bodies of the main telescopic cylinder and the auxiliary telescopic rod are both located in the rotation grooves, and the bearing seat is installed on the upper end surface of the rotation grooves.

[0018] The main supporting part and the auxiliary supporting part leave a gap with the inner wall of the foundation for the swing of the main turning table and the auxiliary turning table cylinder in step S4 and step S6.

[0043] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

[0044] Example

[0045] As mentioned in the background technology, during the iron core processing, when it undergoes a flipping process, lifting equipment is usually used. On the one hand, the investment in equipment and factory buildings is large, and on the other hand, there are great safety hazards for the workers in the factory. Moreover, the stacking process is usually carried out at the same workstation as the flipping process. Although the transportation work is omitted, the two processes can only be carried out separately in sequence, which is inefficient. Therefore, the inventors have made improvements on the existing processing technology and equipment, and designed a new processing method and a supporting processing system, which are explained below with reference to the diagrams.

[0046] refer to Figures 1-7 This embodiment provides a stacking and flipping method for processing a transformer core, comprising the following steps:

[0047] S1: Combine Figure 1 , the iron core is stacked and fixed on the stacking table 1 of the stacking station. In this solution, the stacking station and the flipping station are separately arranged, and the stacking of the iron core can be completed on the stacking table 1 manually or automatically by a machine, and the fixation of the iron core and the stacking table 1 can adopt the existing fixing technology, which will not be elaborated on.

[0048] S2: Control the transfer device 2 to transfer the stacking table 1 from the stacking station to the horizontally arranged main turning table 3 and fix it, which is done by existing manual bolt fixation or other convenient electric fixation methods, without limitation. The main turning table 3 is set in the foundation 4, and the foundation 4 is provided with a support seat 5. In this solution, combined with Figure 4, the support base 5 includes an intermediate support portion 51 and main support portions 52 and auxiliary support portions 53 on both sides, and a hinge seat 6 is provided on the support base 5. The hinge seat 6 is installed on the main support portion 52. The main turntable 3 is hinged to one side of the hinge seat 6. The main turntable 3 can rotate in the vertical direction around the hinge seat 6. Moreover, when the main turntable 3 is in a horizontal state, the end far from the hinge seat 6 is located on a number of supports 14. Combined with Figure 5 , a plurality of columns 15 are provided in the foundation 4 below the main turntable 3, and a number of supports 14 are respectively located on the plurality of columns 15. The supports 14 can support the bottom of the end of the main turntable 3 far from the hinge seat 6, improving the stability of the main turntable 3.

[0049] S3: Control the transfer device 2 to transfer the receiving bracket 7 to the auxiliary turntable 8 provided with water and fix it. The fixing method can be fixed by means of electromagnetic suction or the like, without limitation. Combined with Figure 2 and Figure 3 , the auxiliary turntable 8 is provided in the foundation 4 and is hinged to the other side of the hinge seat 6. The auxiliary turntable 8 can rotate in the vertical direction around the hinge seat 6.

[0050] It should be noted that since the iron core is in a horizontal state on the main turntable 3 and has a large size, and is in a vertical state on the receiving bracket 7 after flipping and has a small size, the length of the main turntable 3 is greater than the length of the auxiliary turntable 8. However, their widths are the same. The main turntable 3 and the auxiliary turntable 8 are flush with the upper end surface of the foundation 4 in the non-working states of steps S2 and S3. This design makes the turntable completely hidden inside the foundation 4 in the non-working state, keeping the ground flat and avoiding personnel tripping or equipment collision caused by the equipment protruding. And the midlines of both of them in the length direction are coplanar. At the same time, the coplanar arrangement of the midlines provides an accurate positioning reference for the subsequent transfer device 2, ensuring that the transfer vehicle can accurately align along the center line when driving in.

[0051] S4: Push the auxiliary turntable 8 to rotate 90° upward around the hinge seat 6, driving the receiving bracket 7 to rotate to a position perpendicular to the main turntable 3. A number of auxiliary telescopic cylinders 9 are provided on the support base 5 below the auxiliary turntable 8. The output end of the auxiliary telescopic cylinder 9 is hinged to the bottom surface of the auxiliary turntable 8, and the upper end of the cylinder barrel is hinged to the bearing seat 10 on the support base 5. In this solution, the auxiliary telescopic cylinders 9 are arranged at intervals along the length direction of the support base 5, and the output end is hinged to the central position of the bottom surface of the auxiliary turntable 8. The auxiliary telescopic cylinders 9 are installed at the position of the auxiliary support portion 53.

[0052] S5: Push the tabletop of the auxiliary flipping table 8 to extend until it tightly abuts against the side of the iron core, specifically against the iron core clamping piece or the foot pad. The extension method of the tabletop of the auxiliary flipping table 8 is designed such that the auxiliary flipping table 8 includes a support frame 81, and the support frame 81 is connected to the hinge seat 6 and the auxiliary telescopic cylinder 9. The support frame 81 is connected with an extension table 82 through an extension device. The support frame 81 forms a U-shaped structure to surround the extension table 82, and the extension device is arranged between the extension table 82 and the support frame 81. Combining Figure 7 , the extension device includes that a plurality of lifting motors 16 are installed between the extension table 82 and the support frame 81, and the output ends of the plurality of lifting motors 16 are connected with a plurality of screw jacks 17 through a linkage assembly 18. The linkage assembly 18 can be specifically realized through components such as a speed reducer, a coupling, and a steering gear. The existing technology can be adopted, which does not affect the novelty of the conceived lifting extension table 82 proposed in this solution. The output end of the screw jack 17 is fixed to the bottom of the extension table 82. Moreover, in order to improve the stability of the movement of the extension table 82, a plurality of guide rods are arranged on the bottom surface of the extension table 82 and are slidably connected to the support frame 81 to limit the movement of the extension table 82. After the auxiliary platform drives the receiving bracket 7 to rotate 90°, the lifting motor 16 drives the extension table 82 to extend through the screw jack to tightly abut against the iron core clamping piece or the foot pad on the lamination table 1, and then the side of the iron core contacts the receiving bracket 7 to support it.

[0053] S6; Push the main flipping table 3 to rotate around the hinge seat 6. Combining Figure 5 , a plurality of main telescopic cylinders 11 are arranged on the support seat 5 below the main flipping table 3, and the output ends of the main telescopic cylinders 11 are hinged to the bottom surface of the main flipping table 3, and the upper ends of the cylinder barrels are hinged to the bearing seats 10 on the support seat 5. In this solution, the main telescopic cylinders 11 are arranged at intervals along the width direction of the support seat 5, and the output ends are hinged to the middle line position of the bottom surface of the main flipping table 3. The upper ends of the cylinder barrels of the main telescopic cylinders 11 are connected to the main support part 52.

[0054] Moreover, combining Figure 4 and Figure 5 , the height of the intermediate support part 51 is higher than the heights of the main support part 52 and the auxiliary support part 53, which facilitates the installation and operation of the main telescopic cylinder 11 and the auxiliary telescopic cylinder 9 at the bottom of the flipping table. And the height of the main support part 52 is higher than the height of the auxiliary support part 53. The purpose is that the bottom of the auxiliary flipping table 8 needs to install an extension device to leave an installation space for it.

[0055] Synchronously control the contraction of the auxiliary telescopic cylinder 9 until the auxiliary flipping table 8 is driven to reset, and control the tabletop of the auxiliary flipping table 8 to retract. After the receiving bracket 7 tightly abuts against the side of the iron core, through the synchronous action of the main telescopic cylinder 11 and the auxiliary telescopic cylinder 9, it is ensured that during the flipping process of the iron core, the receiving bracket 7 always supports the iron core, ensuring the stability of the iron core. During the flipping process, the fixation between the iron core and the lamination table 1 is released and the iron core is fixed to the receiving bracket 7.

[0056] It should be noted that, in combination with Figure 6 , on the end faces of the main support part 52 and the auxiliary support part 53 facing away from each other, a plurality of rotating grooves 12 are vertically formed. The rotating grooves 12 are U-shaped, and the openings face the inner wall of the foundation 4. The cylinders of the main telescopic cylinder 11 and the auxiliary telescopic rod are both located in the rotating grooves 12, and the bearing seat 10 is installed on the upper end face of the rotating groove 12. The upper end of the cylinder is hinged to the bearing seat 10. There is a gap between the main support part 52 and the auxiliary support part 53 and the inner wall of the foundation 4, which is used for the swinging of the cylinder barrels of the main turntable 3 and the auxiliary turntable 8 in step S4 and step S6. When the main telescopic cylinder 11 and the auxiliary telescopic cylinder 9 act, the cylinder will swing under the reaction force. The U-shaped rotating groove 12 and the gap with the foundation 4 ensure the swinging space of the cylinder. Moreover, the plurality of columns 15 for installing the support 14 are arranged at intervals, and the gaps are aligned with the rotating grooves 12 to prevent the columns 15 from blocking the swinging of the main telescopic cylinder 11.

[0057] In addition, when the main turntable 3 in step S2 and the auxiliary turntable 8 in step S3 are in the horizontal position, they are located on the support base 13. The support base 13 is provided with multiple groups on both the main support part 52 and the auxiliary support part 53, and is spaced on both sides of each rotating groove 12. The main turntable 3 and the auxiliary turntable 8 can be supported by the bearing seat 10 to ensure the stability when the iron core is on them.

[0058] S7: Control the transfer device 2 to transfer the receiving bracket 7 to the next working station to complete this flipping. Control the main telescopic cylinder 11 to contract, drive the main turntable 3 to reset and release the fixation with the lamination table 1, and transport the lamination table 1 back to the lamination station to perform the lamination work of the next iron core.

[0059] Based on the above lamination and flipping method for processing, in this embodiment, a corresponding system is designed to implement the above method, which specifically includes:

[0060] The foundation 4 is opened below the reference plane 19, and a support seat 5 is arranged inside it;

[0061] The hinge seat 6 is installed at the middle position of the support seat 5, and a main flipping system and an auxiliary flipping system are hinged on both sides of it;

[0062] The main flipping system includes a main turntable 3. A main telescopic cylinder 11 is installed on the support seat 5 at the bottom of the main turntable 3. The output end of the main telescopic cylinder 11 is hinged to the bottom surface of the main turntable 3, and the upper end of the cylinder is hinged to the bearing seat 10 on the support seat 5. The main turntable 3 is driven by the main telescopic cylinder 11 to rotate around the hinge seat 6, which is the core process for flipping the iron core.

[0063] Auxiliary flipping system, including an auxiliary flipping table 8, a main telescopic cylinder 11 is installed on a support base 5 at the bottom of the auxiliary flipping table 8, the output end of the auxiliary telescopic cylinder 9 is hinged to the bottom surface of the auxiliary flipping table 8, and the upper end of the cylinder barrel is hinged to a bearing block 10 on the support base 5. The auxiliary telescopic cylinder 9 is used to push the auxiliary flipping table 8 to rotate around the hinge seat 6, driving the receiving bracket 7 to receive the iron core.

[0064] In addition, the main telescopic cylinder 11 and the auxiliary telescopic cylinder 9 can adopt multiple oil cylinders to achieve a small length and a large stroke, so that the depth of the foundation 4 can be reduced.

[0065] Laminating table 1, used for laminating the iron core, can be detachably fixed to the main flipping table 3, realizing the separation of the laminating station and the flipping station. Since the laminating table 1 and the flipping table are separate and independent, one flipping table can be used in combination with multiple laminating platforms, improving the iron core manufacturing efficiency and reducing equipment investment.

[0066] Receiving bracket 7, used to receive the iron core after the laminating table 1 is flipped, is detachably fixed to the auxiliary flipping table 8, enabling the flipped iron core to be transported to the next station.

[0067] Transfer device 2, using a transfer vehicle with lifting and moving functions, is used for the transfer of the laminating table 1 and the receiving bracket 7. The size and model of the transfer vehicle can be selected according to the sizes of the laminating table and the transfer bracket, as long as it can lift and move the two with the iron core.

[0068] It should be noted that both the laminating table 1 and the receiving bracket 7 are integrally set as gantry structures, that is, U-shaped structures with openings facing each other, for the transfer device 2 to drive in and out. The transfer device 2 enters the bottom of the laminating table 1 and the receiving bracket 7 through the U-shaped structure, lifts the two off the ground through the lifting function, and then drives itself to drive the two to move to the corresponding positions.
