[0021] 1.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] One of the purposes of the present invention is to provide a transformer coil shaping device, referring to Figure 1-Figure 9As shown, it includes a body 100 and a transformer coil 101, a moving platform 200 is arranged in the body 100, a motor 201 is arranged at the bottom of the moving platform 200, an output end of the motor 201 passes through the moving platform 200 and a main gear 202 is arranged at the end, a sub-gear 203 is arranged vertically on the side of the main gear 202, a screw rod 204 is arranged at the end of the sub-gear 203, and a clamping plate 205 is arranged on the surface of the screw rod 204, and the clamping plate 205 is used to clamp and fix the transformer coil 101 placed on the surface of the moving platform 200, and a protective component 300 is arranged above the moving platform 200 to protect The protective component 300 moves to the inside of the transformer coil 101 to protect the coil. A pressure top component 400 is provided above the protective component 300. The pressure top component 400 moves down to the top of the transformer coil 101 to press its surface. An inflatable component 600 is provided below the protective component 300. The inflatable component 600 is used to block the movement path of the coil inside the transformer coil 101 when the transformer coil 101 is fixed. A shaping component 500 is provided outside the transformer coil 101. The shaping component 500 is used to shape the surface coil of the transformer coil 101:

[0042] In the process of shaping the transformer surface coil, it is often impossible to shape the inner ring. The coil is easily warped inside, which makes it impossible for the coil to be smoothly mounted on the pre-set support, resulting in poor coil shaping effect. Therefore, the protection component 300 includes a first gas rod 301 arranged on the top of the body 100, and the piston rod at the end of the first gas rod 301 is provided with a base plate 302. The surface of the base plate 302 is provided with a through groove, and four inner supporting arc blocks 303 are provided under the base plate 302. The inner supporting arc blocks 303 are symmetrical, and the outer surface of the inner supporting arc blocks 303 is provided with air bags 304, which are adapted to the size of the inner ring of the transformer coil 101, and a fixing component is provided between the inner supporting arc blocks 303. The fixing component is used to squeeze the airbag 304 to fix and limit the transformer coil 101. During the shaping process of the outer surface of the transformer coil 101, the piston rod at the end of the first air rod 301 drives the base plate 302 to move downward, so that the inner supporting arc block 303 arranged under the base plate 302 moves to the inside of the transformer coil 101. The airbag 304 arranged on the surface of the inner supporting arc block 303 resists the radial force generated when the outer surface of the transformer coil 101 is squeezed, thereby avoiding the internal coil of the transformer coil 101 from warping during the shaping process, affecting the adaptation effect of the later transformer, thereby protecting the internal coil of the transformer coil 101 during the shaping process and improving the coil shaping effect.

[0043] In the process of shaping the transformer, when the surface of the transformer coil 101 is in an arc shape, the transmission shaping device needs to perform compression shaping operations on the coils in different directions during the process of compacting and shaping the coil, which is inefficient. Therefore, the fixing component includes a support plate arranged at the bottom of the base plate 302, a moving rod 305 is arranged at the end of the support plate, a fixing block 306 is arranged at the end of the moving rod 305, an elastic member 307 is arranged on the surface of the moving rod 305, and the two ends of the elastic member 307 are respectively connected to the fixing block 306 and the support plate. The shaping component 500 includes a support plate arranged at the bottom of the transformer coil 10 1, a moving track 501 is provided on the surface of the moving track 501, an electric telescopic rod 503 is provided at the end of the moving track 502, a moving frame 504 is provided at the end of the electric telescopic rod 503, a rotating roller 505 is provided inside the moving frame 504, a pressing roller 507 is provided outside the rotating roller 505, a spring body 506 is provided between the rotating roller 505 and the pressing roller 507, when the extension block 403 drives the rack 405 to move downward in the vertical direction, the arc groove 404 at the end of the extension block 403 presses the moving rod 305 during the movement, so that the moving rod 305 pushes the elastic The parts 307 move in the direction of separation on both sides, so that the fixing block 306 fixes the inner wall of the transformer coil 101 and further protects the inside of the coil. When the transformer coil 101 is fixed, the main gear 202 is driven to rotate in the opposite direction by starting the motor 201, so that the auxiliary gear 203 drives the screw rod 204 to rotate, and the clamping plate 205 provided on the surface of the screw rod 204 moves away from each other, and the moving platform 200 is controlled to move downward, so that the transformer coil 101 is in a suspended fixed state. At this time, the electric telescopic rod 503 at the end of the moving trolley 502 is controlled to make the electric telescopic rod 50 The telescopic rod at the end 3 drives the moving frame 504 to move in the horizontal direction until the pressure roller 507 provided inside the moving frame 504 is attached to the outside of the transformer coil 101. Since a spring body 506 is provided between the rotating roller 505 and the pressure roller 507, the shaping force can be adjusted in a buffering manner to avoid deformation and damage of the transformer coil 101 due to excessive force. When the adjustment is completed, the moving trolley 502 is controlled to move on the surface of the moving track 501. Therefore, the ring can be shaped without dead angles, and the angle can be kept consistent during the shaping process to improve the shaping effect.

[0044] In the process of shaping the external coil of the transformer coil 101, in order to prevent the top coil from being loose, the top pressing assembly 400 includes a second cylinder 401 arranged on the top of the body 100, and the piston rod at the end of the second cylinder 401 is provided with a step plate 402, and an extension block 403 is provided at the center of the step plate 402. The extension block 403 moves to the through groove opened on the surface of the base plate 302, and controls the piston rod at the end of the second cylinder 401 to drive the step plate 402 to move in the vertical direction until the bottom of the step plate 402 moves to the surface of the transformer coil 101. In the process of shaping the transformer coil 101, the step plate 402 always remains in contact with the top of the transformer coil 101 and compacted, thereby preventing the top of the coil from being loose.

[0045] In the process of shaping the transformer coil 101, in order to improve the shaping effect of the internal coil of the transformer coil 101, arc grooves 404 are provided on both sides of the extension block 403, and the depth of the arc grooves 404 gradually decreases along the vertical upward direction. The arc grooves 404 are adapted to the ends of the moving rods 305. Racks 405 are provided on both sides of the extension block 403. The racks 405 are symmetrical. Inflatable components 600 are provided on both sides of the racks 405. The inflatable components 600 include a half gear 601 provided on one side of the rack 405. When the rack 405 moves in the vertical direction, the half gear 601 is driven. The gear 601 meshes and rotates, and an eccentric wheel 602 is provided at the end of the half gear 601. The eccentric wheel 602 rotates coaxially with the half gear 601. A column 603 is provided on one side of the eccentric wheel 602. A sealing column 604 is provided on the inner wall of the column 603 for sliding. The end of the sealing column 604 is in contact with the surface of the eccentric wheel 602. A return spring 605 is provided between the sealing column 604 and the column 603. In the natural state, the eccentric wheel 602 is horizontal, and the end of the column 603 is connected to the airbag 304 through a rubber tube. When the second cylinder 401 drives the step plate 402 to move downward in the vertical direction, The extension block 403 drives the rack 405 to move downward in the vertical direction. During the downward movement of the rack 405, the rack 405 drives the half gear 601 to mesh and move. During the rotation, the half gear 601 drives the eccentric wheel 602 to rotate coaxially. Since the eccentric wheel 602 is horizontal in the natural state, when the half gear 601 rotates to 180 degrees, the eccentric wheel 602 is still horizontal. During this process, the eccentric wheel 602 pushes the sealing column 604 when it rotates, and the sealing column 604 slides on the inner wall of the column barrel 603. Since the sealing column 604 and the column barrel 603 are in a sealed state Therefore, the sealing column 604 squeezes the air inside the column tube 603 during the movement, and the air flows from the port of the column tube 603 to the inside of the airbag 304 through the rubber tube. Therefore, when the air inside the airbag 304 is filled with air to reach the preset pressure, the preset pressure can ensure that the internal coil of the transformer coil 101 is compressed and shaped. Since the sealing column 604 will not continuously inflate the airbag 304, there is no need for the one-way airbag 304 to explode due to excessive gas. Therefore, the internal coil of the transformer coil 101 can be quickly shaped, thereby improving the shaping efficiency of the device.

[0046] When in use, the transformer coil 101 is placed on the surface of the mobile platform 200, and the control motor 201 drives the main gear 202 to rotate, so that the auxiliary gear 203 drives the screw rod 204 to rotate, so that the clamping plate 205 on the surface of the screw rod 204 moves in a relative direction, and the quadrant of the arc-shaped transformer coil 101 is fixed and limited. The piston rod at the end of the first gas rod 301 drives the base plate 302 to move downward, so that the inner supporting arc block 303 set under the base plate 302 moves to the inside of the transformer coil 101, and the air bag 304 set on the surface of the inner supporting arc block 303 presses the surface of the transformer coil 101 The radial force generated during external extrusion is resisted to prevent the internal coil of the transformer coil 101 from warping during the shaping process, which affects the adaptation effect of the transformer in the later stage, thereby protecting the internal coil of the transformer coil 101 during the shaping process and improving the coil shaping effect. The piston rod at the end of the second cylinder 401 is controlled to drive the step plate 402 to move in the vertical direction until the bottom of the step plate 402 moves to the surface of the transformer coil 101. During the shaping process of the transformer coil 101, the step plate 402 always keeps in close contact with the top of the transformer coil 101, thereby preventing the top of the coil from being loose.

[0047] When the extension block 403 drives the rack 405 to move downward in the vertical direction, the arc groove 404 at the end of the extension block 403 presses the moving rod 305 during the movement, so that the moving rod 305 pushes the elastic member 307 to move in the direction of separation on both sides, so that the fixing block 306 fixes the inner wall of the transformer coil 101. When the transformer coil 101 is fixed, the main gear 202 is driven to rotate in the opposite direction by starting the motor 201, so that the auxiliary gear 203 drives the screw rod 204 to rotate, and the clamping plate 205 provided on the surface of the screw rod 204 moves away from each other. , control the moving platform 200 to move downward, so that the transformer coil 101 is in a suspended fixed state, adjust the electric telescopic rod 503 at the end of the moving trolley 502, so that the telescopic rod at the end of the electric telescopic rod 503 drives the moving frame 504 to move in the horizontal direction, until the pressure roller 507 provided inside the moving frame 504 is attached to the outside of the transformer coil 101. Since a spring body 506 is provided between the rotating roller 505 and the pressure roller 507, the shaping force can be adjusted in a buffering manner to avoid deformation and damage of the transformer coil 101 due to excessive force;

[0048] When the second cylinder 401 drives the step plate 402 to move downward in the vertical direction to press and limit the top coil of the transformer coil 101, the rack 405 provided at the bottom of the step plate 402 drives the half gear 601 to engage and rotate, and the half gear 601 drives the eccentric wheel 602 to rotate to push the sealing column 604, and the sealing column 604 slides on the inner wall of the column barrel 603. Since the sealing column 604 and the column barrel 603 are in a sealed state, the sealing column 604 squeezes the air inside the column barrel 603 during the movement, and the air flows from the port of the column barrel 603 through the rubber tube to the inside of the airbag 304. Therefore, when the air inside the airbag 304 is filled with air to reach a preset pressure, the preset pressure can ensure the external force for pressing and shaping the internal coil of the transformer coil 101, thereby improving the shaping efficiency of the device.

[0049] A second object of the present invention is to provide a transformer coil shaping method, comprising any one of the above transformer coil shaping devices, comprising the following steps:

[0050] S1. Place the transformer coil 101 on the surface of the moving platform 200, control the motor 201 to drive the main gear 202 to rotate, and make the secondary gear 203 drive the screw rod 204 to rotate, so that the clamping plate 205 on the surface of the screw rod 204 moves in a relative direction, and the quadrant of the arc-shaped transformer coil 101 is fixed and limited;

[0051] S2, controlling the protection component 300 to move downward in the vertical direction to the inside of the transformer coil 101 to protect the internal coil, while the protection component 300 fixes the inner wall of the transformer coil 101, and controlling the shaping component 500 to perform annular shaping on the fixed outer coil of the transformer coil 101;

[0052] S3, control the top pressing assembly 400 to move downward to press the top of the transformer coil 101, so that the top pressing assembly 400 always keeps in close contact and compaction with the top of the transformer coil 101 to prevent the top of the coil from being loose. At the same time, during the downward movement of the top pressing assembly 400, drive the inflation assembly 600 to inflate the inside of the protection assembly 300 to achieve the shaping of the internal coil of the transformer coil 101.
