Description

Technical Field

[0001] The utility model relates to the technical field of transformer skeleton production, in particular to a transformer skeleton flash removal device. Background Art

[0002] The transformer skeleton, also known as the transformer wire frame, is an important part of the transformer structure. It is usually produced by heating and extruding plastic raw materials. The upper and lower molds fit tightly together, and the product is formed in one piece. The skeleton can provide winding space for the copper wire in the transformer and fix the magnetic core in the transformer. The skeleton material can be made of plastic. The shape of the transformer skeleton is not the same. It can be designed according to the needs of the manufacturer and then manufactured using molds. However, when manufacturing the mold, sometimes flashing occurs. The so-called flashing refers to burrs or burrs, which mostly occur at the position where the mold is separated and combined. Therefore, the flashing on the skeleton needs to be removed before use.

[0003] In the prior art, dry ice is first used to quickly cool the transformer skeleton, and the burrs are quickly solidified, and then a roller is used to clean the burrs on the transformer skeleton. However, some skeletons will move to the discharge port, and the cleaning effect is not good, while some will remain at the feed port, which is inconvenient for discharging. Moreover, some of the cleaned plastic burrs will be adsorbed on the surface of the skeleton, and the burrs on its surface need to be cleaned during collection, which reduces production efficiency. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when the transformer skeleton is tipped over, part of the skeleton may be stuck on the cylinder column due to the irregular shape of the transformer skeleton, making it inconvenient to discharge the material, and proposes a transformer skeleton burr removal device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A transformer skeleton flash removal device comprises a support frame, a cleaning cylinder is rotatably connected to the support frame, a hollow tube is rotatably connected inside the cleaning tube, a stirring plate is fixedly connected to the outer wall of the hollow tube, an air jet is fixedly connected to the stirring plate, and the air jet can spray when the stirring plate rotates.

[0007] In order to facilitate the provision of gas to the gas injection hole, preferably, a guide channel is provided in the hollow tube, and a gas injection hole is opened on the gas injection tube, and the gas injection hole is connected to the guide channel.

[0008] In order to facilitate the supply of gas to the hollow tube, further, a booster disk is fixedly connected to the side wall of the cleaning cylinder, and a connecting disk is fixedly connected to the end of the hollow tube. The connecting disk is rotatably connected in the booster disk, and the booster disk is communicated with the hollow tube.

[0009] In order to improve the collision effect between the skeletons, preferably, a mounting seat is fixedly connected to the inner wall of the cleaning cylinder, a guide rod is rotatably connected to the mounting seat, and the outer wall of the guide rod cooperates with the stirring plate.

[0010] In order to facilitate the tilting of the guide rod, preferably, a buffer air bag is provided on the support frame, and the buffer air bag can be against the outer wall of the cleaning cylinder, and the end of the cleaning cylinder away from the mounting seat is fixedly connected with a guide cylinder, and the guide cylinder is slidably connected with a guide rod, and a piston is provided at one end of the guide rod, and the piston is in contact with the inner wall of the guide cylinder, and the other end of the guide rod is fixedly connected with a support plate, and the support plate can be against the outer wall of the guide rod, and the guide cylinder is communicated with the buffer air bag.

[0011] In order to facilitate the discharge of the flash, preferably, a through hole is opened on the cleaning cylinder, and the through hole cooperates with the air injection pipe.

[0012] Compared with the prior art, the utility model provides a transformer frame flash removal device, which has the following beneficial effects:

[0013] 1. The transformer skeleton flash removal device stirs the internal plastic transformer skeleton through the stirring plate, and at the same time, the jet pipe sprays the outside of the plastic transformer skeleton, which can improve the flash collision cleaning effect inside the cleaning cylinder, reduce the number of flashes attached to the skeleton, and then discharge them through the through hole, thereby reducing the cleaning time of the outside of the plastic transformer skeleton during collection, and improving production efficiency;

[0014] 2. The transformer frame deburring device places the plastic transformer frame inside the cleaning cylinder. At this time, the cleaning cylinder can be rotated by the rotating shaft to keep it vertical to the base. Then, under the action of gravity, the plastic transformer frame is placed in the cleaning cylinder, thereby preventing some frames from moving to the discharge port, thereby improving the cleaning effect of the frame;

[0015] 3. The transformer frame deburring device can make the guide rod fit with the inner wall of the cleaning cylinder, so that when the stirring plate rotates, the plastic transformer frame and the outer wall of the guide rod can collide with each other, thereby improving the deburring effect of the plastic transformer frame;

[0016] 4. The transformer frame deburring device can prevent the plastic transformer frame from being stuck between the guide rod and the cleaning barrel by rotating and tilting the guide rod within a certain range. On the other hand, it can also enable the guide rod to guide the plastic transformer frame to prevent some frames from remaining inside the cleaning barrel during discharge, thereby facilitating discharge.

[0017] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The utility model can use the jet pipe to spray the outside of the plastic transformer skeleton, which can improve the collision cleaning effect of the flash inside the cleaning cylinder, reduce the number of flashes attached to the skeleton, and thus reduce the cleaning time of the outside of the plastic transformer skeleton during collection, thereby improving production efficiency. At the same time, the guide rod can guide the plastic transformer skeleton to prevent some skeletons from remaining in the cleaning cylinder during discharging, thereby facilitating discharging. Under the action of gravity, the plastic transformer skeleton will also be in the cleaning cylinder, thereby preventing some skeletons from moving to the discharge port, thereby improving the cleaning effect of the skeleton.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Example:

[0026] Reference Figure 1-Figure 4 A transformer skeleton burr removal device includes a support frame, which can be installed on a base, and a collection box is also arranged on the base, a rotating shaft is rotatably connected to the support frame, and the rotating shaft can be driven to rotate by a hydraulic motor or a driving machine, a cleaning cylinder 1 is fixedly connected to the rotating shaft, and a through hole 101 is also opened on the cleaning cylinder 1. When cleaning the plastic transformer skeleton, dry ice is first used to quickly cool the transformer skeleton so that the burr can be quickly solidified. By using dry ice for rapid cooling, the plastic burr can be solidified into a solid state in a short time, making it easier to clean. After cleaning, the cleaned burr inside can be discharged through the through hole 101.

[0027] In addition, a hollow tube 2 is rotatably connected in the cleaning barrel 1, and the hollow tube 2 can be driven to rotate by an external drive machine or an electric motor. A mounting plate is fixedly connected to the hollow tube 2, and a stirring plate 3 is fixedly connected to the mounting plate. The cross-section of the stirring plate 3 is rectangular, so that it can stir the skeleton and improve the collision cleaning effect between the skeletons.

[0028] In addition, a guide channel is provided in the hollow tube 2, and high-pressure air can be supplied to the guide channel through an external air pump. A jet pipe 4 is fixedly connected to the stirring plate 3, and a jet hole 401 is provided on the outer wall of the jet pipe 4. The jet hole 401 is connected to the guide channel in the hollow tube 2. The gas entering the guide channel can be used to make the jet hole 401 spray, so as to spray the flash adsorbed on the skeleton.

[0029] In order to improve the jet effect of the jet pipe 4 when the hollow tube 2 rotates, a booster disk 6 is fixedly connected to the side wall of the cleaning cylinder 1, and a connecting disk 201 is fixedly connected to the end of the hollow tube 2. The connecting disk 201 is then rotatably connected to the booster disk 6. A cavity is provided in the booster disk 6, and the cavity is connected to the hollow tube 2. In addition, the booster disk 6 is in a fixed state, and the air supply pipeline of an external air pump can be installed on the booster disk 6.

[0030] By placing the plastic transformer frame inside the cleaning barrel 1, the cleaning barrel 1 can be rotated by the rotating shaft to keep it vertical to the base, and then the plastic transformer frame is kept in the cleaning barrel 1 under the action of gravity, thereby preventing some frames from moving to the discharge port, thereby improving the cleaning effect of the frame.

[0031] At this time, the hollow tube 2 rotates, and then the hollow tube 2 will drive the stirring plate 3 to rotate in the cleaning tube 1, and the switch of the air pump is started. At this time, gas is generated in the guide channel in the hollow tube 2, and the gas will be transported to the jet pipe 4 and then ejected from the jet hole 401. During this process, the stirring plate 3 will stir the internal plastic transformer skeleton, and the jet pipe 4 will spray the outside of the plastic transformer skeleton, which can improve the collision cleaning effect of the flash inside the cleaning tube 1, reduce the number of flashes attached to the skeleton, and then be discharged from the through hole 101, so that the cleaning time of the outside of the plastic transformer skeleton can be reduced during collection, thereby improving production efficiency.

[0032] In addition, a mounting seat 102 is fixedly connected to the inner wall of the cleaning cylinder 1, a connecting rod is rotatably connected to the mounting seat 102, and a guide rod 5 is fixedly connected to the connecting rod. When the cleaning cylinder 1 is cleaning the plastic transformer frame, the guide rod 5 always fits with the inner wall of the cleaning cylinder 1. The effect can be achieved by arranging a magnet on the guide rod 5 that matches the cleaning cylinder 1.

[0033] The guide rod 5 is fitted with the inner wall of the cleaning tube 1, so that when the stirring plate 3 rotates, the plastic transformer frame and the outer wall of the guide rod 5 can collide with each other, thereby improving the effect of removing the flash of the plastic transformer frame.

[0034] In addition, a buffer airbag 104 is also provided on the support frame, and the buffer airbag 104 can be abutted against the outer wall of the cleaning tube 1, and the buffer airbag 104 is arranged below the cleaning tube 1, and a guide tube 103 is fixedly connected to one end of the cleaning tube 1 away from the mounting seat 102, and a guide rod is slidably connected to the guide tube 103, a piston is provided at one end of the guide rod, the piston is fitted with the inner wall of the guide tube 103, and a support plate is fixedly connected to the other end of the guide rod, and the support plate can be abutted against the outer wall of the guide rod 5, and the guide tube 103 is communicated with the buffer airbag 104.

[0035] When it is necessary to dump the plastic transformer skeleton after the cleaning inside the cleaning cylinder 1 is completed, the cleaning cylinder 1 can be tilted until it is against the outer wall of the buffer airbag 104. At this time, the gas in the buffer airbag 104 will be transported to the guide cylinder 103, and the support plate on the guide rod will lift the outer wall of the guide rod 5, thereby rotating the guide rod 5. The angle between the guide rod 5 and the cleaning cylinder 1 is in the range of 5°-10°, preferably 7°. The purpose of doing this is, on the one hand, to prevent the plastic transformer skeleton from being stuck between the guide rod 5 and the cleaning cylinder 1, and on the other hand, to enable the guide rod 5 to guide the plastic transformer skeleton, thereby preventing some skeletons from remaining in the cleaning cylinder 1 during discharging, thereby facilitating discharging.
