Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer bakelite frame production, specifically a burr removal device for transformer bakelite frame production. Background Technology
[0002] The transformer bobbin, also known as the transformer wire frame, is an important component of the transformer structure. Its main function is to provide space for the copper wires to wind within the transformer; the parts of the bobbin that provide this function are called winding slots. It also secures the magnetic core within the transformer; the parts of the bobbin where the magnetic core is inserted are called core holes. Deburring devices used in transformer bobbin production are used to remove excess burrs from the edges of the bobbin; common types include sandblasting and roller-type.
[0003] Existing deburring devices for transformer bakelite frames employ drum-type deburring equipment. Multiple through-holes are created in the drum wall to screen the debris generated during the deburring process. The debris falls by gravity, which can lead to reduced screening efficiency due to material accumulation. Some systems also include an inclined screen below the drum. After deburring, the bakelite frame is discharged through a gate, while the abrasive and debris fall onto the screen. The debris and abrasive are separated from the bakelite frame by sliding on the screen, achieving the purpose of screening. However, the short sliding time of the bakelite frame on the screen can result in poor screening efficiency, and the abrasive and debris can easily clog the screen mesh, affecting the subsequent screening efficiency of the bakelite frame and the abrasive and debris. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a burr removal device for the production of bakelite frames for transformers, so as to solve the technical problem that the sieving effect of bakelite frames, abrasives and debris is poor after burr removal.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rough edge treatment device for producing bakelite frames for transformers, comprising a machine body, a servo motor and a reducer respectively installed on one side of the top of the machine body, the output shaft of the servo motor being connected to the reducer, the output end of the reducer being connected to a drive shaft, and a roller being installed at one end of the drive shaft, slide rods being installed on both sides of the interior of the machine body, three slide seats being sleeved on the outer wall of the slide rods, and a sleeve being fixed on one side of the slide seats, a spring being installed inside the sleeve, and a movable rod being placed at the top of the spring, and a screen being installed at the top of the movable rod by bolts, motors being installed on both sides of the machine body, the output end of the motor being connected to a cam through an output shaft, and a self-locking nut being threadedly connected to one end of the slide rod, and the self-locking nut being in contact with one slide seat.
[0006] By adopting the above technical solution, when the drum needs to rotate, the operator can start the servo motor, which in turn drives the drive shaft to rotate, and the drive shaft then drives the drum to rotate.
[0007] Furthermore, a protective mesh pad is installed on the top of the screen, and the protective mesh pad is made of silicone material.
[0008] By adopting the above technical solution, the protective mesh pad can protect the bakelite frame and prevent direct collision between the bakelite frame and the screen.
[0009] Furthermore, the upper part of the outer wall of the sleeve is provided with threads, and a limit sleeve is connected to the outer wall of the sleeve by the threads, and the movable rod passes through the limit sleeve.
[0010] By adopting the above technical solution, the limiting sleeve can be installed on the sleeve to limit the bottom end of the movable rod.
[0011] Furthermore, a bearing seat is installed on the other side of the top of the machine body, and a rotating shaft is connected inside the bearing seat through a bearing, with one end of the rotating shaft fixedly connected to the roller.
[0012] By adopting the above technical solutions, the arrangement of the bearing housing and the rotating shaft can improve the stability of the drum during rotation.
[0013] Furthermore, a movable door is installed on the outer surface of the roller via a hinge, and a latch is also installed between the movable door and the roller.
[0014] By adopting the above technical solution, when it is necessary to rotate the movable door, the staff can first unfasten the latch, and then rotate the movable door.
[0015] Furthermore, the inner wall of the roller is fitted with a liner made of silicone material.
[0016] By adopting the above technical solution, the inner lining can protect the bakelite frame inside the roller and prevent the bakelite frame from directly contacting the roller.
[0017] Furthermore, side plates are fixed to both sides of the top of the screen, and the cam is located directly below the side plates.
[0018] By adopting the above technical solution, when the cam rotates, it will push the screen downward, and the screen will drive the movable rod downward.
[0019] Furthermore, the movable rod is slidably connected to the sleeve, and the movable rod is detachably connected to the screen.
[0020] By adopting the above technical solution, the movable rod can slide inside the sleeve. When the movable rod moves, it will squeeze the spring, causing the spring to be compressed.
[0021] Furthermore, support bases are installed on both sides of the bottom of the machine body, and a collection box is placed inside the lower part of the machine body.
[0022] By adopting the above technical solution, the support base can support the machine body, while the collection box can collect abrasive and debris.

[0024] By adopting the above technical solution, it is convenient for staff to start or stop the motor and servo motor through the control panel.
[0025] In summary, the present invention has the following main advantages:
[0026] 1. This utility model is equipped with a motor, cam, side plate, screen, protective mesh pad, sleeve, spring, and movable rod. When it is necessary to screen bakelite frames and abrasives, the operator can start the motor. The motor drives the cam to rotate, which pushes the side plate down and moves the screen down, which in turn moves the movable rod down. The movable rod compresses the spring, causing it to be compressed. As the cam continues to rotate, it no longer contacts the side plate. At this time, the spring rebounds and pushes the screen up. This repetition causes the screen to vibrate up and down, so as to screen bakelite frames, abrasives, and debris. The bakelite frames, abrasives, and debris form a "throwing-falling" motion on the screen, thereby avoiding material accumulation, reducing the probability of screen mesh blockage, and improving the screening efficiency of bakelite frames, abrasives, and debris.
[0027] 2. This utility model features a protective net pad that protects the bakelite frame, preventing it from colliding directly with the screen when it falls downwards, thus improving the protection of the bakelite frame. A sliding rod and sliding seat are also included to guide the sleeve, facilitating the installation of the sleeve and screen inside the machine body. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0038] The embodiments of this utility model will be described below based on its overall structure.
[0039] Example 1:
[0040] A device for removing burrs in the production of transformer bakelite frames, such as... Figures 1-8 As shown, the device includes a body 1. A servo motor 4 and a reducer 5 are respectively installed on one side of the top of the body 1. The output shaft of the servo motor 4 is connected to the reducer 5. The output end of the reducer 5 is connected to a drive shaft 21, and a roller 9 is installed at one end of the drive shaft 21. Slide rods 23 are installed on both sides inside the body 1. Three slide seats 22 are sleeved on the outer wall of the slide rods 23. A sleeve 15 is fixed on one side of the slide seat 22. A spring 16 is installed inside the sleeve 15, and a movable rod 17 is placed at the top of the spring 16. The spring 16 is made of stainless steel. One end of the slide rod 23 is threaded and a self-locking nut 8 is threaded to one end of the slide rod 23. The self-locking nut 8 is in contact with one slide seat 22. The self-locking nut 8 can limit the slide seat 22 and prevent the slide seat 22 from sliding off the slide rod 23.
[0041] See Figures 1-7A screen 19 is bolted to the top of the movable rod 17. Motors 12 are installed on both sides of the machine body 1. The output end of the motor 12 is connected to a cam 13 through an output shaft. When the drum 9 needs to rotate, the operator can start the servo motor 4, which in turn drives the drive shaft 21 to rotate. The drive shaft 21 then drives the drum 9 to rotate. A protective mesh pad 20 is installed on the top of the screen 19. The protective mesh pad 20 is made of silicone material and has a smooth top. The protective mesh pad 20 can protect the bakelite frame and prevent direct collision between the bakelite frame and the screen 19. The upper part of the outer wall of the sleeve 15 is threaded. A limit sleeve 18 is connected to the threaded part of the outer wall of the sleeve 15. The movable rod 17 passes through the limit sleeve 18. The limit sleeve 18 can be installed on the sleeve 15 to limit the bottom end of the movable rod 17.
[0042] Specifically, side plates 14 are fixed to both sides of the top of the screen 19. The cam 13 is located directly below the side plates 14. When the cam 13 rotates, it pushes the screen 19 downward, which in turn drives the movable rod 17 downward. The screen 19 is made of stainless steel. The movable rod 17 is slidably connected to the sleeve 15. The movable rod 17 and the screen 19 are detachably connected. Support seats are installed on both sides of the bottom of the machine body 1. A collection box 2 is placed inside the lower part of the machine body 1. The support seats can support the machine body 1, and the collection box 2 can collect abrasive and debris. The movable rod 17 can slide inside the sleeve 15. When the movable rod 17 moves, it will compress the spring. 16, which causes the spring 16 to be compressed by force, and the sleeve 15 is slidably connected to the slide rod 23 through the slide block 22. The outer surface of the roller 9 is equipped with a movable door 24 through a hinge, and the outer surface of the roller 9 is also provided with a material port, which corresponds to the movable door 24. A latch 10 is also installed between the movable door 24 and the roller 9. When it is necessary to rotate the movable door 24, the operator can first unfasten the latch 10 and then rotate the movable door 24. A control panel 3 is also installed on one side of the machine body 1. The control panel 3 is electrically connected to the motor 12 and the servo motor 4 respectively, so that the operator can start or stop the motor 12 and the servo motor 4 through the control panel 3.
[0043] Example 2:
[0044] Based on the above embodiment one, in order to avoid direct contact between the bakelite frame and the inner wall of the roller 9, the following structure will be set to protect the bakelite frame.
[0045] See Figures 1-3 The inner wall of the roller 9 is equipped with a liner 11, which is made of silicone material. The liner 11 can protect the bakelite frame inside the roller 9 and prevent the bakelite frame from directly contacting the roller 9. Through holes 25 are provided on the movable door 24, the roller 9 and the inner liner 11, and a mesh is installed in the through holes 25.
[0046] Example 3:
[0047] Based on the above embodiment 1, the following structure will be set to improve the stability of the roller 9 when it rotates.
[0048] Specifically, a bearing seat 6 is installed on the other side of the top of the machine body 1. The bearing seat 6 is connected to a rotating shaft 7 through a bearing, and one end of the rotating shaft 7 is fixedly connected to the drum 9. The arrangement of the bearing seat 6 and the rotating shaft 7 can improve the stability of the drum 9 when it rotates.
[0049] The working principle of this utility model is as follows: First, when using it, the operator first turns on the power, then unfastens the latch 10, and then rotates the movable door 24. After the movable door 24 is rotated and opened, the bakelite frame can be put into the inside of the roller 9, and soft abrasive (such as polyurethane particles or ceramic balls) is added into the inside of the roller 9. After adding, the movable door 24 is closed and the latch 10 is locked. Then, the servo motor 4 is started, which makes the drive shaft 21 rotate. The drive shaft 21 rotates and drives the roller 9 to rotate. At the same time, the bakelite frame tumbles in the roller and collides with the abrasive, thereby performing burr treatment on the bakelite frame.
[0050] After the rough edges are finished and the movable door 24 is in the rotatable open position, turn off the servo motor 4. At this time, first unfasten the latch 10, then rotate the movable door 24 to open it. The worker should hold the movable door 24 with one hand to prevent it from resetting and obstructing the material inlet. Then, start the servo motor 4 and motor 12, so that the servo motor 4 rotates slowly, which in turn drives the roller 9 to rotate slowly. When the material inlet on the roller 9 faces downward, the bakelite skeleton, abrasive, and debris inside the roller 9 will fall out through the material inlet and onto the protective mesh pad 20. At the same time, the motor 12 drives the cam 13 to rotate. The rotation of the cam 13 pushes the side plate 14 down, which in turn drives the screen 19 down, and then drives the movable door 14 to rotate. The moving rod 17 moves down and squeezes the spring 16, causing the spring 16 to be compressed. As the cam 13 continues to rotate, the cam 13 no longer contacts the side plate 14. At this time, the spring 16 rebounds and pushes the screen 19 up. The cam 13 continues to rotate and pushes the screen 19 down. This repetition causes the screen 19 to vibrate up and down, so as to screen the bakelite frame and abrasive. The abrasive and debris fall into the collection box 2. The staff can also take out the collection box 2 and pour the abrasive and debris into the external screening device to separate the abrasive and debris, so as to facilitate the collection of abrasive and reuse. The screening of abrasive and debris is not the focus of this application and will not be described in detail here.
[0051] When the screen 19 needs to be removed, the worker can rotate the self-locking nut 8 on the slide rod 23 to unscrew the self-locking nut 8 from the slide rod 23, and then pull the screen 19 so that the slide block 22 slides out from the slide rod 23. Then the screen 19 can be removed so that the bakelite frame on the screen 19 can be collected.
