Description

Technical Field

[0001] The present invention relates to the technical field of transformer insulation material production, and particularly relates to a half-cutting machine for producing transformer insulation materials. Background Art

[0002] The transformer insulation cylinder is one of the important insulation materials in a transformer, used to wrap the high-voltage coil of the transformer to isolate and protect the coil from electric shock and other damages. When producing the transformer insulation cylinder, according to the specifications and requirements of the transformer, it is necessary to half-cut the insulation cylinder so that the insulation cylinder can wrap the high-voltage coil of the transformer.

[0003] When half-cutting the insulation cylinder, the staff needs to find the midpoint on the insulation cylinder and mark it with a marker pen. Currently, most cutting machines have a relatively simple structure and do not have the function of pushing the insulation cylinder. Therefore, the staff needs to manually push the insulation cylinder to the saw blade of the cutting machine to make the saw blade of the cutting machine half-cut the insulation cylinder. During the operation, if the staff's hand shakes or fails to hold the insulation cylinder firmly, the insulation cylinder will be misaligned, thus affecting the cutting accuracy of the insulation cylinder. Secondly, the staff's hand needs to be close to the saw blade of the cutting machine, and any carelessness will cause injury, presenting a certain safety hazard. Summary of the Invention

Specific embodiments

[0035] The preferred technical solutions of the present invention will be described in detail below with reference to the attached drawings.

[0036] Example 1: As Figures 1 - 7 shown, a half-cutting machine for producing transformer insulating materials includes a mounting frame 1, a support plate 2, a top plate 3, a mounting plate 4, a band saw 5, a side limiting plate 6, an upper limiting plate 7 and a clamping and moving mechanism. Both left and right sides of the bottom of the mounting frame 1 are bolted to the support plate 2. The upper part inside the mounting frame 1 is bolted to the top plate 3. The rear side of the bottom of the mounting frame 1 is bolted to the mounting plate 4. The top of both support plates 2 is bolted to the bottom of the mounting plate 4. The top plate 3 is bolted with a band saw 5 on the top. The band saw 5 and the mounting plate 4 are bolted. A through hole for the saw blade of the band saw 5 to move is opened in the middle of the bottom of the mounting frame 1. Activity openings for the saw blade of the band saw 5 to move are opened on both upper and lower sides of the left part of the mounting frame 1. The saw blade of the band saw 5 passes through the through hole and the activity openings. Side limiting plates 6 are bolted to both left and right sides of the top of the mounting frame 1. Upper limiting plates 7 are bolted to one side of both side limiting plates 6 close to each other. A clamping and moving mechanism is provided on the side limiting plate 6. The clamping and moving mechanism is used to clamp the insulating cylinder and move the insulating cylinder to the position of the band saw 5 so that the band saw 5 can perform half-cutting on the insulating cylinder.

[0037] As Figures 3 - 7As shown in the figure, the clamping and moving mechanism includes a sliding frame 81, clamping plates 82, guide plates 83, a first wedge block 84, a first elastic member 85, a second wedge block 86, a second elastic member 87, a sliding shaft 811 and a power assembly. Sliding frames 81 capable of horizontal sliding are provided inside the side limiting plates 6. Clamping plates 82 capable of horizontal sliding are provided inside the sliding frames 81. The sides of the two clamping plates 82 facing each other are both arc-shaped surfaces to adapt to the contour of the insulating cylinder. Guide plates 83 are connected to the sides of the two side limiting plates 6 away from each other by bolts. Two first wedge blocks 84 capable of horizontal sliding are provided on the sides of the two guide plates 83 facing each other. A first elastic member 85 is connected between the first wedge block 84 and the guide plate 83. The first elastic member 85 is a spring. Two second wedge blocks 86 capable of horizontal sliding are provided on the sides of the two guide plates 83 away from each other. The inclined surfaces on the first wedge block 84 and the second wedge block 86 face in opposite directions. A second elastic member 87 is connected between the second wedge block 86 and the guide plate 83. The second elastic member 87 is a spring. Sliding shafts 811 are connected to the tops of the clamping plates 82 by bolts. A power assembly is provided on the side limiting plates 6. The power assembly is used to drive the clamping plates 82 to drive the insulating cylinder to move, so that the band saw 5 can cut the insulating cylinder in half.

[0038] As Figures 5 - 7 shown in the figure, the power assembly includes an electric slide rail 88 and a sliding plate 89. Electric slide rails 88 are connected to the sides of the two side limiting plates 6 away from each other by bolts. Sliding plates 89 capable of horizontal sliding are provided on the electric slide rails 88. Oblique grooves 810 are formed on the sliding plates 89. The sliding shafts 811 are located in the oblique grooves 810.

[0039] The staff places the insulating cylinder between two clamping plates 82. The side limiting plate 6 and the upper limiting plate 7 limit the insulating cylinder to prevent dislocation or jitter of the insulating cylinder, resulting in higher cutting accuracy. Then, the band saw 5 is started, and the electric slide rail 88 is controlled to drive the slide plate 89 to move backward. The wedge block two 86 on the front side blocks the slide shaft 811, making the slide shaft 811 unable to move backward. Under the action of the inclined groove 810, the two slide shafts 811 move towards each other, so that the two clamping plates 82 can move towards each other to clamp the insulating cylinder. When the slide shaft 811 moves to the position of the front wedge block one 84, under the action of the front elastic member one 85, the slide shaft 811 can cross over the front wedge block one 84. Subsequently, the slide shaft 811 drives the clamping plate 82 to move backward, thereby driving the insulating cylinder to move backward to the position of the band saw 5. The band saw 5 cuts the insulating cylinder in half. The staff does not need to approach the band saw 5, ensuring higher safety. When the slide shaft 811 moves backward to the position of the rear wedge block one 84, under the action of the rear elastic member one 85, the slide shaft 811 can cross over the rear wedge block one 84. At this time, the staff controls the electric slide rail 88 to drive the slide plate 89 to move forward. The rear wedge block one 84 blocks the slide shaft 811, making the slide shaft 811 unable to move forward. Under the action of the inclined groove 810, the two slide shafts 811 move away from each other, so that the two clamping plates 82 can move away from each other to release the cut insulating cylinder. When the slide shaft 811 moves to the position of the rear wedge block two 86, under the action of the rear elastic member two 87, the slide shaft 811 can cross over the rear wedge block two 86. Subsequently, the slide shaft 811 drives the clamping plate 82 to move forward. When the slide shaft 811 moves forward to the position of the front wedge block two 86, under the action of the front elastic member two 87, the slide shaft 811 can cross over the front wedge block two 86. In this way, the slide shaft 811 can move around the guide plate 83 without bringing the cut insulating cylinder back to the position of the band saw 5. At this time, the staff turns off the electric slide rail 88, then places the uncut insulating cylinder between the two clamping plates 82 and continues to cut the insulating cylinder in half. The subsequently cut insulating cylinder can push the previously cut insulating cylinder and push the previously cut insulating cylinder off the mounting rack 1 without manual collection by the staff, making it more convenient to use. The side limiting plate 6 can be disassembled, and the distance between the two side limiting plates 6 can be adjusted according to the size of the insulating cylinder to adapt to insulating cylinders of different sizes. The upper limiting plate 7 can also be disassembled, and the height of the upper limiting plate 7 can be adjusted according to the height of the insulating cylinder to adapt to insulating cylinders of different heights.

[0040] Embodiment 2: On the basis of Embodiment 1, as Figure 8As shown in the figure, it further includes a guiding mechanism. The guiding mechanism includes a mounting block 91, guiding wheels 92 and supporting wheels 93. An installation opening is formed in the middle of the front part of the top plate 3. The saw blade of the band saw 5 passes through the installation opening. Mounting blocks 91 are connected to the rear side of the inner part of the installation opening and the middle of the bottom of the installation frame 1 by bolts respectively. On the left and right sides of the front side of the mounting block 91, a set of rotatable guiding wheels 92 are provided. Each set has two guiding wheels 92. The saw blade of the band saw 5 is located between the two sets of guiding wheels 92, and the saw blade of the band saw 5 contacts the guiding wheels 92. The guiding wheels 92 can guide the saw blade of the band saw 5. Supporting wheels 93 that can rotate are provided on the front side of each mounting block 91. The saw blade of the band saw 5 contacts the supporting wheels 93. The supporting wheels 93 can support the saw blade of the band saw 5, making the saw blade of the band saw 5 run more smoothly and ensuring the flatness of the cutting surface.

[0041] As Figure 9 shown in the figure, it further includes a cooling mechanism. The cooling mechanism includes a liquid storage tank 101, a water pump 102 and a universal pipe 103. The liquid storage tank 101 is connected to the right side of the top of the top plate 3 by bolts. The liquid storage tank 101 is used for storing cutting fluid. The water pump 102 is connected to the right side of the top of the top plate 3 by bolts. The water pump 102 is located on the left side of the liquid storage tank 101. The liquid inlet end of the water pump 102 is connected and communicated with the bottom of the liquid storage tank 101, so that the water pump 102 can pump the cutting fluid in the liquid storage tank 101. A universal pipe 103 is connected to the liquid outlet end of the water pump 102. The nozzle of the universal pipe 103 faces the saw blade of the band saw 5 to spray the cutting fluid onto the saw blade of the band saw 5 to cool the saw blade of the band saw 5 and prevent the saw blade of the band saw 5 from being worn due to excessive temperature.

[0042] As Figure 10 and Figure 11 shown in the figure, it further includes a collection mechanism. The collection mechanism includes a blowing pump 111, a gas guide box 112, a blowing pipe 113, a collection box 114 and a first filter frame 115. The blowing pump 111 is connected to the rear side of the top of the mounting plate 4 by bolts. The gas guide box 112 is connected to the front side of the top of the mounting plate 4 by bolts. The gas outlet end of the blowing pump 111 is connected and communicated with the rear side of the gas guide box 112. The front side of the gas guide box 112 is communicated with the blowing pipe 113. The blowing pipe 113 penetrates through the mounting block 91 at the bottom of the mounting frame 1. The collection box 114 is connected to the front side of the bottom of the mounting frame 1 by bolts. An opening for the saw blade of the band saw 5 to move is formed in the rear side of the bottom of the collection box 114. The saw blade of the band saw 5 passes through the opening. The first filter frame 115 is connected to the front side of the bottom of the collection box 114 by bolts.

[0043] When the insulating cylinder is cut in half, the debris and cutting fluid generated during the cutting of the insulating cylinder fall into the collection box 114 through the through-hole. The staff can start the blowing pump 111, and the blowing pump 111 blows air into the air guide box 112. The air is ejected through the air blowing pipe 113. The air blows the debris and cutting fluid in the collection box 114, blowing the debris and cutting fluid into the first filter frame 115, which facilitates subsequent collection and can prevent debris from accumulating below the through-hole. The cutting fluid passes through the first filter frame 115 and is discharged. The first filter frame 115 can be disassembled to facilitate the cleaning of the debris in the first filter frame 115.

[0044] As Figures 12 - 14 shown, it further includes a cleaning mechanism. The cleaning mechanism includes an air guide pipe 121, an air jet box 122 and a collection assembly. The rear side of the air guide box 112 is communicated with the air guide pipe 121. The air guide pipe 121 and the mounting frame 1 are connected by bolts. The front end of the air guide pipe 121 is communicated with the air jet box 122. Three air jet holes 123 are evenly spaced on the left side of the air jet box 122. A collection assembly is provided on the left support plate 2. The collection assembly is used to collect the blown debris.

[0045] As Figure 12 and Figure 13 shown, the collection assembly includes a collection pipe 124 and a second filter frame 125. The upper part of the left side of the left support plate 2 is connected to the collection pipe 124 by bolts. The bottom end of the collection pipe 124 is connected to the second filter frame 125 by bolts.

[0046] A part of the air in the air guide box 112 is ejected from the air jet holes 123 through the air guide pipe 121 and the air jet box 122, and is ejected onto the saw blade of the band saw 5, and is ejected onto the side of the saw blade. In this way, the debris remaining in the tooth grooves of the saw blade can be removed, avoiding the phenomenon of tool jamming and ensuring the cutting quality. The removed debris falls into the collection pipe 124 and the second filter frame 125 for collection. The cutting fluid remaining on the saw blade will also be blown into the collection pipe 124 and the second filter frame 125, and then discharged through the second filter frame 125. The second filter frame 125 can be disassembled to facilitate the cleaning of the debris in the second filter frame 125.

[0047] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
