Description

Technical Field

[0001] This utility model relates to a forming mold, and more particularly to a dry transformer coil forming mold, belonging to the technical field of transformer coil processing equipment. Background Technology

[0002] A dry-type transformer is a power transformer whose core and windings are not immersed in a liquid (such as insulating oil). Its windings and core are cooled and insulated by air or solid insulating materials (such as epoxy resin). Due to its design characteristics, dry-type transformers have significant advantages in safety, environmental friendliness, and ease of maintenance, and are widely used in various special environments. The fabrication of the coils inside a dry-type transformer requires the use of molds; specifically, dry-type transformer coil molds are needed for forming and manufacturing.

[0003] To maintain stability, the lower mold of traditional dry-type transformer coil forming molds usually adopts a fixed structure, which cannot be disassembled and replaced. Therefore, when producing coils of different specifications or types, it is impossible to switch molds, so multiple equipment are required for processing, resulting in low actual equipment utilization. In addition, the lower mold may age after long-term use, resulting in serious wear, breakage, deformation and other problems. However, since it cannot be replaced individually, the entire mold set needs to be replaced, resulting in high mold usage costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dry-type transformer coil forming mold that facilitates the disassembly and assembly of the lower mold.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A dry-type transformer coil forming mold includes a support frame, an electric cylinder fixedly mounted on the top of the support frame, a connecting plate fixedly mounted on the output end of the electric cylinder, an annular pressure plate mounted on the bottom of the connecting plate, a base plate disposed below the annular pressure plate, a lower mold mounted on the top of the base plate, and an easy-to-disassemble structure provided on the base plate. The easy-to-disassemble structure includes multiple fixing blocks fixedly mounted on the side of the lower mold, a first insert rod connected to the base plate mounted on the fixing block, a limit hole being formed at one end of the first insert rod, and multiple second insert rods connected to the first insert rod mounted on the base plate.

[0007] Preferably, a plurality of guide rods are fixedly installed at the bottom of the connecting plate, a plurality of insertion holes adapted to the guide rods are provided on the lower mold, and a plurality of shock absorbers are provided between the connecting plate and the annular pressure plate.

[0008] Preferably, the support frame is provided with a first protective plate and a second protective plate on its side, the back of the second protective plate is provided with a plurality of toothed grooves, a drive motor is fixedly installed on the top of the support frame, and the output end of the drive motor is provided with a gear that meshes with the toothed grooves.

[0009] Preferably, a protective shell is fixedly installed on the outside of the drive motor.

[0010] Preferably, a plurality of fixing plates are fixedly installed on the side of the base plate, a fixing frame is fixedly installed on the top of the fixing plate, an electric telescopic rod is fixedly installed on the bottom of the fixing frame, a fixing frame is fixedly installed on the output end of the electric telescopic rod, a connecting block is sleeved on the fixing frame, and a suction cup is fixedly installed on the bottom of the connecting block.

[0012] The beneficial effects of this utility model are as follows:

[0013] Compared to traditional transformer coil forming methods where the lower mold cannot be disassembled, this invention, through its easily detachable structure, allows for the replacement of the lower mold while maintaining its stability. When producing coils of different specifications or types, the mold can be quickly switched, significantly improving the utilization rate of the processing equipment.

[0022] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1-7 As shown, this embodiment of a dry-type transformer coil forming mold includes a support frame 1. An electric cylinder 2 is fixedly installed on the top of the support frame 1. A connecting plate 3 is fixedly installed on the output end of the electric cylinder 2. An annular pressure plate 4 is installed on the bottom of the connecting plate 3. A base plate 5 is provided below the annular pressure plate 4. A lower mold 6 is installed on the top of the base plate 5. An easy-to-disassemble structure 7 is provided on the base plate 5. The easy-to-disassemble structure 7 includes multiple fixing blocks 8 fixedly installed on the side of the lower mold 6. A first insert rod 9 connected to the base plate 5 is installed on the fixing block 8. A limit hole 10 is opened at one end of the first insert rod 9. Multiple second insert rods 11 connected to the first insert rod 9 are installed on the base plate 5. Preferably, a spring 12 connected to the base plate 5 is provided on the second insert rod 11; or the second insert rod 11 is provided with a thread that mates with the inside of the limit hole 10 to improve the stability of the lower mold 6 after installation.

[0024] The easily detachable structure 7 allows for the replacement of the lower mold 6, enabling quick mold switching when producing coils of different specifications or types, thus shortening the production cycle and improving equipment utilization. The fixed block 8, the first insertion rod 9, and the second insertion rod 11 maintain the stability of the lower mold 6. When a different specification of lower mold 6 needs to be replaced, the multiple second insertion rods 11 are pulled outwards to detach from the inside of the first insertion rod 9, and the first insertion rod 9 is then pulled out of the fixed block 8 to remove the lower mold 6 for replacement. After the replaced lower mold 6 is placed on the base plate 5, the first insertion rod 9 is inserted into the fixed block 8. The fixing block 8 is connected to the base plate 5, and the limiting hole 10 at one end of the first insertion rod 9 is connected to the second insertion rod 11 to fix the first insertion rod 9. In order to maintain the stability of the lower mold 6, the fixing block 8 can also be provided with a thread that mates with the outside of the first insertion rod 9. After the first insertion rod 9 is screwed to the fixing block 8 through the thread, the limiting hole 10 at the end of the first insertion rod 9 is aligned with the insertion hole of the second insertion rod 11. This structure can maintain the stability of the lower mold 6 while disassembling and replacing the lower mold 6 separately, without replacing the entire mold set, which helps to reduce the processing cost of the transformer coil.

[0025] like Figure 2 and Figure 3 As shown, multiple guide rods 13 are fixedly installed at the bottom of the connecting plate 3, and multiple insertion holes 14 adapted to the guide rods 13 are opened on the lower mold 6. Multiple shock absorbers 15 are provided between the connecting plate 3 and the annular pressure plate 4. When the annular pressure plate 4 descends to press the coil in the lower mold 6, the multiple guide rods 13 at the bottom of the connecting plate 3 are first inserted into the insertion holes 14 to maintain the stability of the descending annular pressure plate 4 and avoid deviation when the annular pressure plate 4 descends. The multiple shock absorbers 15 between the connecting plate 3 and the annular pressure plate 4 can buffer the excessive pressure when the annular pressure plate 4 is pressed.

[0026] like Figure 5 and Figure 6 As shown, multiple first protective plates 16 are fixedly installed on the support frame 1, and a second protective plate 17 is movably installed on one end of the support frame 1. Multiple toothed grooves 18 are opened on the back of the second protective plate 17. A drive motor 19 is fixedly installed on the top of the support frame 1, and a gear 20 that meshes with the toothed grooves 18 is fixedly installed on the output end of the drive motor 19. When the multiple first protective plates 16 and the second protective plate 17 are closed, they can seal the support frame 1, preventing debris from flying out when the annular pressure plate 4 presses the coil inside the lower mold 6, improving operational safety, and maintaining the sealing of the equipment when it is not in use. The drive motor 19 can drive the gear 20 to rotate, causing the second protective plate 17 to move upward, thus opening one end of the support frame 1, making it convenient for personnel to remove the finished coil from the lower mold 6.

[0027] like Figure 6As shown, a protective shell 21 is fixedly installed on the outside of the drive motor 19. The protective shell 21 has multiple heat dissipation holes 22, and a maintenance cover 23 is provided at one end of the protective shell 21. The protective shell 21, heat dissipation holes 22 and maintenance cover 23 can protect the drive motor 19. At the same time, the multiple heat dissipation holes 22 on the protective shell 21 can dissipate the heat generated by the drive motor 19 in a timely manner, and the maintenance cover 23 can facilitate personnel to perform maintenance on the drive motor 19 without disassembling the protective shell 21.

[0028] like Figure 6 As shown, in a preferred embodiment, a first magnetic ring 24 is fixedly installed on the inner side of the inspection cover 23, and a second magnetic ring 25 that is magnetically connected to the first magnetic ring 24 is fixedly installed on the protective shell 21. The inspection cover 23 can be fixed on the protective shell 21 by the attraction between the first magnetic ring 24 and the second magnetic ring 25, and the inspection cover 23 can be opened easily.

[0029] like Figure 7 As shown, multiple fixing plates 26 are fixedly installed on the side of the base plate 5. A fixing frame 27 is fixedly installed on the top of the fixing plate 26. An electric telescopic rod 28 is fixedly installed on the bottom of the fixing frame 27. A fixing frame 29 is fixedly installed on the output end of the electric telescopic rod 28. A connecting block 30 is sleeved on the fixing frame 29. A suction cup 31 is fixedly installed on the bottom of the connecting block 30. Activating the multiple electric telescopic rods 28 to extend them can drive the suction cup 31 to move downwards until the suction cup 31 is adsorbed onto the clean base surface. This can further improve the stability of the equipment and prevent the base plate 5 from becoming unstable when the annular pressure plate 4 is in operation.

[0030] like Figure 7 As shown, both the fixed frame 29 and the connecting block 30 have connecting holes 32. A third insert rod 33 is movably installed inside the connecting hole 32, and a latch 34 is fixedly installed at one end of the third insert rod 33. The third insert rod 33 is inserted into the connecting hole 32 to connect the connecting block 30 and the fixed frame 29. After rotating the third insert rod 33 to adjust the angle of the latch 34 to be perpendicular to the angle of the connecting hole 32, the connecting block 30 can be fixed inside the fixed frame 29, so that the suction cup 31 can be installed on the electric telescopic rod 28. When the third insert rod 33 is rotated to adjust the angle of the latch 34 to be consistent with the angle of the connecting hole 32, the third insert rod 33 can be pulled out from the connecting hole 32, which facilitates the disassembly and assembly of the suction cup 31.

[0031] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
