Description

Technical Field

[0001] The utility model relates to the technical field of insulating material processing, in particular to an oil channel sheet covering device. Background Art

[0002] A transformer usually consists of the following parts: ① Iron core: made of silicon steel sheets or other magnetic materials, used to concentrate the magnetic field and improve the efficiency of the transformer; ② Coil: used to transfer electrical energy; ③ Insulating material: Insulating material is sandwiched between the coil layers to provide interlayer insulation for the coil; ④ Cooling system: used to dissipate heat and ensure that the transformer maintains an appropriate temperature during operation; ⑤ Protection device: used to monitor and protect the normal operation of the transformer, such as temperature control device, overload protection device, etc.

[0003] like Figure 1 As shown, the structure of the insulating material includes a sheet of insulating paper 11 and a plurality of oil channel sheets 12. The method of making the insulating material is: first, all the oil channel sheets 12 are placed closely together, then a layer of glue is applied on the top surface of the oil channel sheets 12, a sheet of insulating paper 11 is laid flat, and then the oil channel sheets 12 are pasted on the insulating paper 11 one by one. In order to reinforce the oil channel sheets 12, the staff will press the oil channel sheets 12 by hand or use a flat plate to press the oil channel sheets 12. The problem is that: pressing the oil channel sheets 12 by hand is inefficient, and there is also the problem that the hands are easily stuck to the glue; using a flat plate to press the oil channel sheets 12, although all the oil channel sheets 12 can be pressed at one time, it requires the staff to frequently take and place and press the flat plate. It is necessary to provide a device that can automatically press the oil channel sheets 12. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides an oil channel plate pressing device, which can automatically press the oil channel plate.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] An oil channel plate covering device comprises a power mechanism, two left-right symmetrically arranged regulating mechanisms, a storage plate, a main plate and a rectangular frame.

[0007] The rectangular frame includes a top plate, a bottom plate and two side plates, and a column is arranged at each end of the bottom plate;

[0008] The storage plate is located below the main board, and both are slidably matched with the two columns. The top of the storage plate is used to place the insulating paper and oil channel sheet to be pressed, and a pressure plate is provided at the bottom of the main board;

[0009] The regulating mechanism includes a rotating rod and two hinged rods symmetrical about the center of the rotating rod. The center of the rotating rod is rotatably arranged on the corresponding side plate. The two ends of the rotating rod are respectively hinged to a hinged rod. The two hinged rods are respectively hinged to the end of the storage plate and the end of the main plate.

[0010] The power mechanism is arranged on the top plate for moving the main plate up and down, or the power mechanism is arranged on the outer wall of one of the side plates for rotating the rotating rod.

[0011] Furthermore, the longitudinal section of the storage plate is an inverted U-shape, and the longitudinal section of the main board is an upright U-shape.

[0012] Furthermore, a plurality of pressure strips are arranged in an array at the bottom of the pressure plate, and the length direction of the pressure strips is perpendicular to the length direction of the oil channel sheet.

[0013] Furthermore, the pressure plates are slidably fitted on the two columns, and two guide rods are provided on the top of the pressure plate. The two guide rods penetrate the main board upward, and round blocks with a diameter larger than the guide rods are provided on the guide rods. The round blocks are supported on the top surface of the main board. Springs are provided on the outer periphery of the guide rods, and the two ends of the springs are respectively connected to the main board and the pressure plate.

[0014] Furthermore, a pull-out plate is slidably provided on the top of the storage plate, and a handle is provided on the outer side of the pull-out plate. The insulating paper and oil channel sheet to be laminated are placed on the top of the pull-out plate.

[0015] The beneficial effects of the utility model are that the regulating mechanism, the placement plate and the main board are cleverly designed, and the insulating paper and the oil channel sheet to be laminated can be placed on the placement plate, and then the distance between the placement plate and the main board is reduced under the action of the power mechanism until the pressure plate under the main board contacts and presses the oil channel sheet to stop, thereby automatically completing the laminating task of the oil channel sheet and increasing the tightness of the connection between the oil channel sheet and the insulating paper. This process does not require the staff to press the oil channel sheet by hand, nor does it require the staff to frequently take in and press the flat plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 2 , Figure 3 As shown, this embodiment provides an oil channel plate covering device, including a power mechanism 1, two left-right symmetrically arranged regulating mechanisms 2, a storage plate 3, a main board 4 and a rectangular frame 5.

[0020] Specifically, the rectangular frame 5 is composed of a top plate 51 , a bottom plate 52 and two side plates 53 . A column 521 is disposed at each end of the bottom plate 52 , and the top of the column 521 is connected to the top plate 51 .

[0021] Specifically, the storage plate 3 is located below the main board 4, the longitudinal section of the storage plate 3 is an inverted U-shape, and the longitudinal section of the main board 4 is an upright U-shape, both of which are slidably fitted on the two columns 521, and the top of the storage plate 3 is used to place the insulating paper 11 and the oil channel sheet 12 to be covered, and the bottom of the main board 4 is provided with a pressure plate 41, which is used to press the oil channel sheet 12 downward.

[0022] Specifically, each regulating mechanism 2 includes a rotating rod 21 and two hinged rods 22. The two hinged rods 22 are symmetrical about the rotating rod 21. The center of the rotating rod 21 is rotated on the inner wall of the corresponding side panel 53. A hinged rod 22 is hinged at each end of the rotating rod 21. The two hinged rods 22 are hinged to the end of the storage plate 3 and the end of the main board 4 respectively.

[0023] Specifically, the power mechanism 1 can be a hydraulic cylinder or a motor. If the power mechanism 1 is a hydraulic cylinder, the power mechanism 1 is arranged on the top plate 51 to move the main plate 4 up and down; if the power mechanism 1 is a motor, the power mechanism 1 is arranged on the outer wall of one of the side plates 53 to rotate the rotating rod 21. In the drawings of this embodiment, the power mechanism 1 is shown as a hydraulic cylinder.

[0024] The covering principle is as follows: the insulating paper 11 and the oil channel sheet 12 to be covered are placed on the top of the storage plate 3; the main board 4 is moved downward by the power mechanism 1, and with the cooperation of the two regulating mechanisms 2, when the main board 4 moves downward, it will prompt the storage plate 3 to move upward, thereby reducing the distance between the main board 4 and the storage plate 3, and stop when the pressure plate 41 under the main board 4 contacts and presses the oil channel sheet 12; the main board 4 is moved upward again by the power mechanism 1, so that the storage plate 3 is reset downward to its original position.

[0025] Before laminating, the staff needs to lay a piece of insulating paper 11 on the top of the storage plate 3, and then paste the oil channel sheets 12 coated with glue on the insulating paper 11 one by one. In order to leave more space for the staff to perform the above operations, this embodiment takes the following measures: Figure 2 As shown, a pull-out plate 31 is slidably provided on the top of the storage plate 3, and a handle 32 is provided on the outside of the pull-out plate 31. Before pressing, the staff pulls out the pull-out plate 31 through the handle 32, lays the insulating paper 11 flat on the top of the pull-out plate 31; then sticks the oil channel sheets 12 coated with glue on the insulating paper 11 one by one; then pushes the pull-out plate 31 in, and starts the power mechanism 1 to press the oil channel sheets 12.

[0026] In order to provide a certain degree of buffering for the pressing process of the oil channel plate 12, the present embodiment adopts the following measures: Figure 2 , Figure 3As shown, the two ends of the pressure plate 41 are respectively slidably matched with the two columns 521, and two guide rods 43 are provided on the top of the pressure plate 41. The two guide rods 43 penetrate the main board 4 upward, and a round block 431 with a diameter larger than itself is provided on the guide rod 43. The round block 431 is supported on the top surface of the main board 4. A spring 44 is provided on the outer periphery of the guide rod 43, and the two ends of the spring 44 are respectively connected to the main board 4 and the pressure plate 41.

[0027] During the covering pressure, the main board 4 is moved downward by the power mechanism 1. When the pressure plate 41 below the main board 4 contacts the oil channel plate 12, the main board 4 continues to move downward. At this time, the oil channel plate 12 forms an upward extrusion on the pressure plate 41, causing the two springs 44 to gradually contract. In this process, the downward pressure of the pressure plate 41 on the oil channel plate 12 gradually increases, thereby achieving pressure buffering.

[0028] More specifically, the bottom array of the pressure plate 41 has multiple pressure strips 42, and the length direction of the pressure strips 42 is perpendicular to the length direction of the oil channel plate 12. Through experiments, this embodiment has found that the oil channel plate 12 can also be covered with multiple pressure strips 42, thereby increasing the tightness of the connection between the oil channel plate 12 and the insulating paper 11.

[0029] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
