[0002] A power transformer is a static electrical device used to convert a given alternating voltage (current) into one or more different voltages (currents) at the same frequency. It is a static device with two or more windings. Existing power transformers require insulating cardboard tubes during assembly for internal insulation to prevent internal discharge. The cardboard tubes are manufactured by beveling both ends and then gluing the beveled edges together to form the tube.

[0003] To ensure the tightness of the connection at the chamfered cut surface, multiple clamps are usually used to clamp the two ends of the chamfered cut surface and then allow it to stand still. However, the middle position of the chamfered cut surface is not subjected to force, resulting in insufficient tightness of the connection and the shaping effect needs to be improved.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a shaping device for producing transformer insulating cardboard tubes, including a support frame 1 and a side plate 2 connected to the side of the support frame 1. The top of the support frame 1 is connected to a support plate 3 for supporting the cardboard tube. The two support plates 3 form a V-shaped structure, and a support roller 4 is evenly rotatably connected to the inner side of the support plate 3. When the cardboard tube is put in, it can be pushed to move closer to the side plate 2. The cardboard tube can drive the support roller 4 to rotate, avoiding direct contact with the support plate 3. The friction is small, making it easier to push the cardboard tube in and pull it out, which is convenient for people to operate. Side plate 2 is connected to a shaping mechanism for shaping the cardboard tube. The shaping mechanism includes two lifting plates 5, multiple springs 16, two connecting plates 6, and two arc-shaped pressure plates 7. The two lifting plates 5 are arranged vertically. The connecting plates 6 are movably connected to the lifting plates 5, and their ends are connected to the arc-shaped pressure plates 7. The bottom of the upper arc-shaped pressure plate 7 protrudes downwards, while the top of the lower arc-shaped pressure plate 7 is recessed downwards. When the two arc-shaped pressure plates 7 press against the cardboard tube, they not only have a high degree of fit with the cardboard tube but also ensure uniform force on the chamfered cut surface, improving the tightness of the connection and achieving a good shaping effect. The two ends of the springs 16 are connected to the lifting plates 5 and the connecting plates 6. The lifting plates 5 are connected to a drive mechanism for driving the two lifting plates 5 closer together or further apart.

[0022] After the cardboard tubes are placed, the motor 12 drives the screw 13 to rotate, causing the two moving blocks 14 to move closer to each other. The moving blocks 14 drive the lifting plate 5 to move, causing the two arc-shaped pressure plates 7 to move closer to each other. The arc-shaped pressure plates 7 press against the chamfered surface of the cardboard tubes. At this time, the spring 16 is in a compressed state, which facilitates the shaping of the cardboard tubes.

[0023] The shaping mechanism also includes two slide grooves 17 and two guide blocks 18. The slide grooves 17 are set inside the lifting plate 5, and the guide blocks 18 are slidably connected to the slide grooves 17 and fixedly connected to the connecting plate 6. The guide blocks 18 can slide within the slide grooves 17, improving the stability of the movement of the arc-shaped pressure plate 7 and playing a good guiding role.

[0024] Spring 16 is located in slide groove 17, and both ends of spring 16 are fixedly connected to lifting plate 5 and guide block 18.

[0025] The drive mechanism includes two moving blocks 14, a screw 13, a motor 12, and two guide holes. The motor 12 drives the screw 13 to rotate and is connected to the bottom of the side plate 2. The screw 13 drives the two moving blocks 14 to move closer or further apart. The moving blocks 14 are slidably connected to the guide holes, which are located in the side plate 2. The moving blocks 14 are fixedly connected to the corresponding lifting plates 5. The motor 12 drives the screw 13 to rotate, which in turn drives the two moving blocks 14 to move closer or further apart, thereby driving the two lifting plates 5 to move closer or further apart. The moving blocks 14 slide within the corresponding guide holes, improving the stability of the movement of the lifting plates 5.

[0026] The screw 13 is threadedly connected to two moving blocks 14, and the internal threads of the two moving blocks 14 are in opposite directions.

[0027] The side plate 2 is provided with four rectangular holes 11, and sliding blocks 15 are slidably connected to the rectangular holes 11. The sliding blocks 15 are connected to connecting blocks 10, and the connecting blocks 10 are fixedly connected to the lifting plate 5. When the lifting plate 5 moves, the connecting blocks 10 are driven to move synchronously, so that the sliding blocks 15 slide in the corresponding rectangular holes 11, further ensuring the stability of the movement of the lifting plate 5 and achieving a good guiding purpose.

[0028] A pressing plate 9 is provided above the support plate 3, and a connecting rod 8 is connected to the top of the pressing plate 9. The connecting rod 8 is fixedly connected to the moving block 14 located above. When the arc-shaped pressing plate 7 presses against the chamfered surface of the cardboard tube, the pressing plate 9 has not yet contacted the cardboard tube. The motor 12 continues to drive the two moving blocks 14 to move closer to each other, and simultaneously drives the two lifting plates 5 to move closer to each other. The guide block 18 slides in the slide groove 17, and the spring 16 is compressed, which increases the pressure applied by the arc-shaped pressing plate 7 to the cardboard tube until the pressing plate 9 presses against the cardboard tube. At this point, the two moving blocks 14 stop moving, thereby achieving good positioning of the cardboard tube and improving its stability.

[0029] Figure 5 Point a in the middle is the cut surface of the beveled corner of the cardboard tube.

[0030] Working Principle: The cardboard tube is placed on the support plate 3 and pushed forward, connecting it to the side plate 2, and then stops moving. The motor 12 drives the screw 13 to rotate, causing the two moving blocks 14 to move closer together, simultaneously driving the two lifting plates 5 to move closer together. The two arc-shaped pressure plates 7 press against the chamfered surface of the cardboard tube. The movement of the upper moving block 14 simultaneously drives the connecting rod 8 and the pressing plate 9 to move, but at this time, the pressing plate 9 has not yet contacted the cardboard tube. The motor 12 continues to drive the screw 13 to rotate, causing the two moving blocks 14 to move further closer. The arc-shaped pressure plates 7 gradually press against the cardboard tube, the guide block 18 slides in the slide groove 17, and the spring 16 is gradually compressed, causing the pressure applied by the arc-shaped pressure plates 7 to the cardboard tube to gradually increase. Until the pressing plate 9 presses against the cardboard tube, the two arc-shaped pressure plates 7 are pressed against the chamfered surface of the cardboard tube, facilitating the shaping process of the cardboard tube and improving its stability. After the cardboard tube is shaped, the motor 12 drives the screw 13 to rotate, causing the two moving blocks 14 to move away from each other, the pressing plate 9 to separate from the cardboard tube, and the two lifting plates 5 to move away from each other, driving the arc-shaped pressing plate 7 to separate from the cardboard tube, thereby loosening the cardboard tube and facilitating unloading.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
