Description

Technical Field

[0001] The utility model belongs to the technical field of insulating cardboard processing, and particularly relates to a water-brushing and bending system for transformer insulating cardboard. Background Art

[0002] Transformer insulating cardboard is made of pulp, fibers or fiber compounds, and is usually treated by impregnating insulating paint to improve its electrical and mechanical properties; this insulating cardboard is made by single-layer or multi-layer lamination, and has high strength and good insulation performance.

[0003] The internal space of the transformer is limited. By bending, the insulating cardboard can better adapt to the internal structural layout of the transformer, make full use of the space, and ensure the compactness and rationality among components; the bent insulating cardboard is more flexible during installation, can easily bypass other components, reduce the installation difficulty and shorten the installation time.

[0004] The distilled water softening method is a method for bending transformer insulating cardboard. This method is applicable to cases where the size of the insulating cardboard is large or more precise control of the bending angle is required. Bend lines are drawn as marks at the positions where the insulating cardboard needs to be bent, and a brush is used to dip distilled water and evenly brush it at the bend lines of the insulating cardboard. The brushing width is determined according to actual needs (such as 160 mm); after standing for a period of time (such as more than 0.5 hours) to allow the distilled water to be evenly absorbed, and after checking that the water absorption on both sides of the insulating cardboard is uniform, bending is carried out.

[0005] Chinese patent document CN214726918U discloses a bending device for transformer insulating cardboard, including a base, a pedestal and a support seat. One end of the top of the base is welded with a pedestal. A positioning hole is arranged on one side of the pedestal, and a feeding hole is arranged on one side of the positioning hole. A small punching machine is installed on the top of the pedestal through a positioning seat and bolts. One end of the pedestal is installed with a support seat through bolts. A PLC controller is installed on one side of the support seat through screws. A fixing block is welded on the top of the support seat, a storage chamber is arranged in the fixing block, and an end cover is arranged at one end of the fixing block, and an electric hydraulic cylinder is installed at one end of the end cover through bolts. This bending device for transformer insulating cardboard has diverse functions, is easy to operate, saves manpower and material resources, meets various requirements in use, and is suitable for wide promotion and use.

[0006] Although the above bending device realizes the bending operation of the insulating cardboard, it does not solve the problem of automatically softening the insulating cardboard with distilled water.

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1 shown, the transformer insulating cardboard water-brushing and bending system includes a water-brushing device and a bending device 5. The water-brushing device includes a water-brushing workbench 1, a support frame 2, a water-pumping component 3 and a smearing component 4. The upper end of the water-brushing workbench 1 is a rectangular horizontal workbench surface, and the left end of the horizontal workbench surface is fixedly supported by two vertical support legs. The lower ends of the vertical support legs are fixedly connected to a horizontal circular fixing plate, and the horizontal circular fixing plate is placed on the ground, making the water-brushing workbench 1 more stable; the right end of the horizontal workbench surface is fixedly connected to the left side surface of the rectangular table 51 of the bending device 5 placed on the ground, and the stable support of the horizontal workbench surface of the water-brushing workbench 1 is realized through the vertical support legs and the rectangular table 51. A support frame 2 is fixedly installed in the middle width direction of the horizontal workbench surface. The support frame 2 includes vertical support plates at the front and rear ends. The upper ends of the vertical support plates are fixedly connected to a horizontal support plate. A water-pumping component 3 is fixedly arranged above the horizontal support plate. A smearing component 4 is arranged below the side of the horizontal support plate. The smearing component 4 is communicated with the water-pumping component 3.

[0027] In a specific implementation, distilled water is placed in the pumping assembly 3. The bent portion of the transformer insulating cardboard marked is placed under the coating assembly 4 on the water-brushing workbench 1. The pumping assembly 3 and the coating assembly 4 are turned on. The pumping assembly 3 extracts distilled water and sends it into the coating assembly 4. The coating assembly 4 applies the distilled water to the portion of the transformer insulating cardboard that needs to be bent. During this application process, the staff can adjust the application position of the transformer insulating cardboard to meet the requirements of applying distilled water at different positions.

[0028] On one side between the coating assembly 4 and the bending device 5, a robotic arm and an insulating cardboard turntable for applying distilled water are fixedly installed. This robotic arm and insulating cardboard turntable are mature technical means in the prior art, and the present utility model does not show them here. At the same time, the present utility model does not elaborate on their structures and working principles here. After the coating assembly 4 applies distilled water to the portion of the transformer insulating cardboard that needs to be bent, this robotic arm can clamp the insulating cardboard coated with distilled water and send it to the insulating cardboard turntable, place it for a period of time to allow the distilled water to be evenly absorbed, and then this robotic arm clamps the soaked insulating cardboard and sends it to the bending device 5 to start the subsequent bending work of the bending device 5 on the insulating cardboard.

[0029] In order to reduce the burden on the staff during the work of applying distilled water to the bent portion of the transformer insulating cardboard, the pumping assembly 3 is provided in this embodiment. Refer to Figure 2 , the pumping assembly 3 includes a water tank 31 and a water pump 33. The water tank 31 is fixedly installed on one side (rear side) of the upper surface of the horizontal support plate of the support frame 2. The water pump 33 is fixedly installed in the middle of the upper surface of the horizontal support plate of the support frame 2 through a water pump support. The input end of the water pump 33 is communicated with one side of the water tank 31 close to the water pump 33 through a water inlet pipe 32. The output end of the water pump 33 is fixedly connected with a water outlet pipe 34. The water outlet pipe 34 is a redundant hose.

[0030] The above-mentioned water tank 31 is jointly composed of a water tank body and a circular tank cover threadedly connected to the circular hole in the upper part of the water tank body. And this circular tank cover itself has a breathable function, which is a mature technical means in the prior art. When this circular tank cover is screwed on to seal the upper part of the water tank body, it can also ensure the air circulation and air pressure balance inside and outside the water tank body; during the implementation of the above-mentioned water pump 33, a digital display time control switch timer of model LBDS-86 needs to be installed. Its working principle is to control the water output by setting the length of the water output time or the water output cycle. It is a mature technical means in the prior art. The present utility model only borrows its function of being able to control the water output regularly here and does not elaborate on its structure and working principle here.

[0031] Refer to Figure 1 、 3The smearing assembly 4 includes a motor 41, a reciprocating threaded rod 42, a sliding limit assembly and a water brushing mechanism 44. The sliding limit assembly includes a sliding body 43 and a long rectangular plate 45. The motor 41 is fixedly mounted on the front side of the middle top end of the vertical support plate at the front end of the support frame 2. The output end of the motor 41 is fixedly connected to the reciprocating threaded rod 42 through a coupling. The front and rear ends of the reciprocating threaded rod 42 pass through the vertical support plate of the support frame 2 and are rotatably connected to the vertical support plate. In order to make the rotation of the reciprocating threaded rod 42 smoother, a bearing seat can be installed on the vertical support plate, and the two ends of the reciprocating threaded rod 42 are rotatably connected to the bearing seat. The outer periphery of the reciprocating threaded rod 42 is covered with a sliding body 43, and a circular hole is provided on the sliding body 43. A steering block is installed in the circular hole. The steering block is provided with an internal threaded hole, and the steering block is threadedly connected to the outer surface of the reciprocating threaded rod 42 through the internal threaded hole. See. Figure 4 The front and rear ends of the rectangular plate body 452 are respectively fixedly connected to the inner side of the vertical support plate of the support frame 2. A horizontal slide groove 451 is opened in the middle of the left surface of the rectangular plate body 452. A limiting protrusion is integrally formed on the right side of the sliding body 43. The size and shape of the limiting protrusion are adapted to the slide groove 451, and the limiting protrusion is slidably connected to the inner surface of the slide groove 451.

[0032] The connection between the reciprocating threaded rod 42 and the sliding body 43 is a mature technology in the prior art. Its operating principle is as follows: rotational motion is converted into linear motion. When the reciprocating threaded rod 42 rotates, the sliding body 43 moves along the grooves on the reciprocating threaded rod 42. Due to the pitch characteristics of the grooves, when the reciprocating threaded rod 42 rotates one circle, the sliding body 43 moves axially along the reciprocating threaded rod 42 by a distance of one pitch. This allows rotational motion to be converted into linear motion. Reciprocating motion is achieved because the reciprocating threaded rod 42 has two thread grooves with the same pitch but opposite rotation directions. Therefore, when the reciprocating threaded rod 42 rotates continuously, the steering block installed in the circular hole of the sliding body 43 can switch between the two thread grooves. This design enables the reciprocating threaded rod 42 to achieve reciprocating motion of the sliding body 43 without changing the rotation direction of the main shaft. The rotation of the reciprocating threaded rod 42 drives the sliding body 43 to move back and forth. This is a mature technology in the prior art. The present invention will not elaborate on its structure and operating principle here.

[0033] A water brushing mechanism 44 is fixedly installed on the left side of the sliding body 43. The water brushing mechanism 44 includes a water brushing inlet pipe, a perforated water box and bristles. The upper end of the water brushing inlet pipe is connected to the lower end of the water outlet pipe 34, and the lower end of the water brushing inlet pipe is connected to the upper end of the perforated water box. A sponge block is provided inside the perforated water box, and several groups of bristles are provided below the perforated water box. The bristles are installed in the water outlet holes on the lower surface of the perforated water box. After the distilled water flows out of the water hole, it is evenly dipped and brushed on the bending line of the insulating cardboard through the bristles.

[0034] The above-mentioned water brushing mechanism 44, since surface tension plays a key role in the process of sponge block absorbing water, the surface tension formed by the interaction force between water molecules makes the water molecules in a state higher than the surrounding horizontal plane, and the molecules on the surface of the sponge block will also be affected by this tension, thereby guiding the water molecules to flow into the interior of the sponge block along the direction of the surface tension. The water pump 33 is adjusted to control the extraction of a certain amount of distilled water from the water tank 31 and then transport it to the porous water box, and then the distilled water penetrates into the sponge block. This amount of water can allow the sponge block to absorb water while not causing excessive leakage of distilled water from the sponge block due to excessive distilled water, thereby affecting the distilled water coating effect of the water brushing structure 44 on the transformer insulating cardboard. The water pump 33 will regularly transport a certain amount of distilled water to the sponge block, so that the water flow rate of the water brushing mechanism 44 can be controlled during the distilled water coating process on the transformer insulating cardboard with different water absorption properties.

[0035] In order to reduce the burden on workers during the bending work of transformer insulation paperboard, refer to Figure 5 The bending device 5 includes a rectangular table 51, a second electric cylinder, a fixed plate 5432, a first electric cylinder 541 and a bending plate 542. The left end of the rectangular table 51 is fixedly connected to the right end of the horizontal work surface of the water-brushing workbench 1. A vertical placement groove 52 is provided in the middle width direction of the upper end of the rectangular table 51. A horizontal operation groove 53 that passes through the vertical placement groove 52 is provided at the lower part of the rectangular table 51. The operation groove 53 is a step structure formed by combining the left end operation groove and the right end operation groove. The height of the right end operation groove is greater than that of the left end operation groove. The end of the right end operation groove adjacent to the left end operation groove passes through the vertical placement groove 52 and is coplanar. The right inner surface of the right end operation groove is fixedly provided with the second electric cylinder and the first electric cylinder 541 from top to bottom.

[0036] See also Figure 5 and Figure 6, the fixed end of the first electric cylinder 541 is fixedly installed in the middle of the inner surface on the right side of the operation groove 53 through bolts. The end of the piston rod at the output end of the first electric cylinder 541 is fixedly connected with a bending plate 542. One end of the bending plate 542 away from the piston rod is an arc structure. An elastic fixing component 543 is arranged above the bending plate 542, and the elastic fixing component 543 is used to fix the insulating cardboard in the vertical direction during bending; the elastic fixing component 543 includes a spring 5433 and a fixing plate 5432. A horizontal sliding groove two 5431 is opened in the middle of the upper surface of the bending plate 542. The length direction of the sliding groove two 5431 is the same as the moving direction of the piston rod of the second electric cylinder. A sliding convex block is integrally formed at the lower end of the fixing plate 5432, and the sliding convex block is slidably connected with the inner surface of the sliding groove two 5431. Springs 5433 are fixedly connected to both the left and right ends of the right side surface of the fixing plate 5432. The right ends of the two springs 5433 are fixedly connected with vertical connecting plates 5434, and the tops of the two connecting plates 5434 are fixedly connected to the upper surface of the right end operation groove. The second electric cylinder is fixedly installed in the middle of a pair of connecting plates 5434. The fixed end of the second electric cylinder is fixedly installed in the upper part of the inner surface on the right side of the operation groove 53 through bolts. The end of the piston rod at the output end of the second electric cylinder is fixedly connected to the middle of the fixing plate 5432 through bolts. After the insulating cardboard is inserted and positioned from the vertical placement groove 52, the second electric cylinder is started to drive the fixing plate 5432 to press and fix the insulating cardboard in the vertical direction. Due to considerations such as possible occlusion in the composition resulting in overly complex lines, Figure 5 and Figure 6 the second electric cylinder and the piston rod of the second electric cylinder are not shown in

[0037] The above-mentioned bending plate 542 is made of a common metal material, and its thickness is about 8 mm, which can endow the bending plate 542 with certain strength and durability, so as to better complete the bending operation of the insulating cardboard. Moreover, the whole bending plate 542 is smoothed. The edge of one end of the bending plate 542 away from the first electric cylinder 541 is smoothed into a circular arc, so that the bending plate 542 will not damage the transformer insulating cardboard itself during the bending operation of the transformer insulating cardboard. The left end of the sliding groove two 5431 is about 0.8 mm away from the outer side of the circular arc edge of the bending plate 542, ensuring that the fixing plate 5432 can compact the insulating cardboard before bending.

[0038] Since it is considered that the common thickness of insulating cardboard ranges from 0.8 mm to 6 mm, the distance between the upper surface of the bending plate 542 and the upper side surface of the left end of the operation groove 53 is about 6 mm, so that the bending plate 542 can meet the bending operations of most transformer insulating cardboard with different thicknesses. The intersection of the upper side surface of the left end of the operation groove 53 and the inner surface of the left side of the vertically placed groove 52 is designed with a right angle, which can make the insulating cardboard better stressed during the bending operation of the bending plate 542 on the transformer insulating cardboard.

[0039] It should be specifically noted that the specific installation methods of the water pump 33, the motor 41, the first electric cylinder 541 and the second electric cylinder, the connection method of the circuit and the control method adopted in the present utility model are all conventional designs, and the present utility model will not elaborate in detail.

[0040] The working principle of the present utility model is as follows:

[0041] In the specific implementation, the transformer insulating cardboard is placed on the water-brushing workbench 1, and the marked bending position of the insulating cardboard is directly below the water-brushing mechanism 44. Distilled water is injected into the water tank 31, and the water pump 33 is started. The water pump 33 transports the distilled water in the water tank 31 to the water-brushing mechanism 44 through the water inlet pipe 32 and the water outlet pipe 34; the motor 41 is started to drive the reciprocating threaded rod 42 to rotate, thereby driving the sliding body 43 to slide back and forth to apply distilled water to the bending position of the insulating cardboard; the set sliding limit component can limit the sliding body 43 when the reciprocating threaded rod 42 rotates to drive the sliding body 43 to move, so that the moving path of the sliding body 43 is a stable horizontal movement.

[0042] The robotic arm arranged on the side between the coating assembly 4 and the bending device 5 clamps and sends the insulating cardboard coated with distilled water to the insulating cardboard turntable. After the distilled water is evenly absorbed by the insulating cardboard, the robotic arm clamps and sends the wetted insulating cardboard to the bending device 5 and automatically inserts the insulating cardboard into the vertically placed groove 52 for bending operation.

[0043] In the subsequent bending operation of the insulating cardboard by the bending device 5, after the insulating cardboard is inserted vertically into the vertically placed slot 52 from top to bottom and the bottom end is placed in place, the second electric cylinder is activated to extend the second piston rod, and at the same time, the first electric cylinder 541 is activated to extend the first piston rod. The second electric cylinder drives the fixed plate 5432, and the first electric cylinder 541 drives the bending plate 542 to move towards the insulating cardboard to press it tightly. After the fixed plate 5432 first presses and fixes the transformer insulating cardboard in the vertical direction, the bending plate 542 continues to move horizontally to perform the bending operation on the transformer insulating cardboard. At the same time, when the first electric cylinder 541 extends the piston rod to drive the bending plate 542 to move to perform the bending operation on the transformer insulating cardboard, the length of the piston rod extended by the first electric cylinder 541 can be controlled, so as to flexibly change the bending angle of the bending plate 542 on the transformer insulating cardboard according to requirements.

[0044] In the bending operation of the transformer insulating cardboard, the cardboard is completely inserted into the vertically placed slot 52. At this time, the lower end of the cardboard is completely horizontally abutted against the bottom wall of the inner surface of the lower part of the operation slot 53. At this time, the bending position of the insulating cardboard is the highest. Thus, when inserting the insulating cardboard into the vertically placed slot 52, only need to completely insert the insulating cardboard so that the lower end of the insulating cardboard is completely horizontally abutted against the bottom wall of the inner surface of the lower part of the operation slot 53, ensuring the precise positioning of the bending position. At the same time, since the operation slot 53 is opened through, when the bending positions of the bent insulating cardboard are different, corresponding horizontal plates with different thicknesses can be placed at the position in the operation slot 53 opposite to the vertically placed slot 52. Then, in the bending operation, insert the insulating cardboard into the vertically placed slot 52, and only need the bottom end of the insulating cardboard to abut against the horizontal plates with different thicknesses.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
