[0040] Reference Figures 1 to 3The utility model proposes an oil-impregnated asbestos cutting device, including a clamp 200 arranged on a base 100, the clamp 200 having a clamping space 210, the clamping space 210 being used for the oil-impregnated asbestos to pass through; a top plate 300 arranged on the base 100, the top plate 300 being used to abut against the front end of the oil-impregnated asbestos passing through the clamping space 210; a cutting knife 400 being rotatably arranged on the base 100, the cutting knife 400 being moved closer to or away from the base 100 after rotation, the cutting knife 400 being used to cut off the oil-impregnated asbestos, and the cutting knife 400 being located between the clamp 200 and the top plate 300.
[0041] In this embodiment, the base 100 is made of a sturdy material, providing a stable foundation for the entire device. A clamp 200 is fastened to one end of the base 100 by bolts or welding. The diameter of the clamping space 210 within the clamp 200 is slightly larger than the diameter of the oil-impregnated asbestos to be cut, allowing the oil-impregnated asbestos to pass smoothly through it. When the oil-impregnated asbestos to be cut passes through the clamping space 210, its position is initially fixed. Furthermore, the clamping space 210 keeps the oil-impregnated asbestos in a straight line, preventing the packing from curling and facilitating the determination of the cutting length.
[0042] The top plate 300 is mounted on the other end of the base 100, opposite the clamp 200. Its surface is finely polished to ensure a tight and smooth contact with the front end of the oil-impregnated asbestos. After the front end of the oil-impregnated asbestos that has passed through the clamping space 210 contacts the top plate 300, the cutting blade 400 cuts the oil-impregnated asbestos, ensuring that the oil-impregnated asbestos is cut to a fixed length.
[0043] The cutting blade 400 located between the clamp 200 and the top plate 300 is rotatably arranged on the base 100 via a high-precision rotating shaft. The cutting blade 400 is made of high-strength alloy steel, and the blade is sharp and wear-resistant.
[0044] During use, the operator only needs to pass the front end of the oil-impregnated asbestos through the clamping space 210 until the front end of the oil-impregnated asbestos abuts against the top plate 300. The operator only needs to rotate the cutting knife 400 to complete the fixed-length cutting of the oil-impregnated asbestos. After the cutting is completed, the cut oil-impregnated asbestos is removed, and then the oil-impregnated asbestos to be cut is continued to be moved to the position where the front end abuts against the top plate 300. The cutting knife 400 is rotated again to complete the fixed-length cutting of the oil-impregnated asbestos again.
[0045] Furthermore, the base 100 has a first groove 110 , and the first groove 110 and the oil-impregnated asbestos passing through the clamping space 210 form a certain angle, and the cutting knife 400 is rotatably disposed in the first groove 110 .
[0046] In this embodiment, the first groove 110 of the base 100 has a certain angle with the oil-impregnated asbestos, and the cutting knife 400 is rotatably arranged therein, which brings significant improvement effects: on the one hand, this angle setting can ensure that the cutting knife 400 can completely cut off the oil-impregnated asbestos after rotation, ensuring the integrity and effectiveness of the cutting, avoiding the situation of uncutting, and improving the success rate and quality of the cutting.
[0047] On the other hand, the cutting blade 400 remains parallel to the side wall of the first groove 110, which enables bevel cutting of oil-impregnated asbestos, meets different cutting requirements, increases the functional diversity and flexibility of the cutting device, and expands its scope of application in practical applications.
[0048] Furthermore, it also includes a rotating pressure plate 500 rotatably set on the base 100, the rotation axis of the rotating pressure plate 500 is parallel to the direction of the oil-impregnated asbestos passing through the clamping space 210, and the rotating pressure plate 500 is close to or away from the clamping space 210 after rotation. The rotating pressure plate 500 is used to compress the oil-impregnated asbestos in the clamping space 210.
[0049] In this embodiment, a rotating pressure plate 500 is provided on the base 100, and its rotation axis is parallel to the direction of the oil-impregnated asbestos passing through the clamping space 210, which brings the following improved effects: on the one hand, after the rotating pressure plate 500 rotates, it can approach and press the oil-impregnated asbestos in the clamping space 210, thereby enhancing the fixing effect of the packing, making it more stable during the cutting process, reducing the cutting error caused by the shaking or displacement of the packing, and thus significantly improving the cutting accuracy and quality.
[0050] On the other hand, the rotating pressing plate 500 can be flexibly moved away from the clamping space 210 as needed, which facilitates the placement and adjustment of the oil-impregnated asbestos, makes the operation more convenient and efficient, and improves work efficiency.
[0051] Furthermore, the clamp 200 includes a fixed plate 220 having a first section 221 and a second section 222, and the first section 221 and the second section 222 are respectively arranged on the base 100, and the fixed plate 220 has a certain angle with the rotation axis of the cutting knife 400; the sliding plate 230 is slidably arranged on the base 100, and after the sliding plate 230 slides, it approaches or moves away from the fixed plate 220, and a clamping space 210 is formed between the sliding plate 230 and the fixed plate 220, and the sliding plate 230 is located on the side of the cutting knife 400 away from the top plate 300, and the sliding plate 230 has a first end 231 and a second end 232, and the first end 231 is closer to the top plate 300 than the second end 232, and the first end 231 has a slope 233, and the slope 233 is parallel to the side wall of the first groove 110.
[0052] In this embodiment, the fixed plate 220 is divided into a first section 221 and a second section 222, located on either side of the cutting blade 400. The fixed plate 220 provides a precise positioning base for the oil-impregnated asbestos to be cut. The sliding plate 230 is slidably mounted on the base 100. By sliding the sliding plate 230, the size of the clamping space 210 can be flexibly adjusted to accommodate the cutting of oil-impregnated asbestos of different sizes.
[0053] The oil-impregnated asbestos passing through the clamping space 210 has a passage path determined by the fixing plate 220. The fixing plate 220 and the rotation axis of the cutting knife 400 have a certain angle, so that the oil-impregnated asbestos always has a certain angle with the cutting knife 400 when being cut. Taking a 45-degree bevel as an example, it can be ensured that the cutting surface of the oil-impregnated asbestos is always a 45-degree bevel, which is convenient for the combination of oil-impregnated asbestos of different lengths.
[0054] The first end 231 has an inclined surface 233 , and the inclined surface 233 of the first end 231 is always parallel to the side wall of the first groove 110 , which can prevent the sliding plate 230 from interfering with the rotation and cutting of the cutting blade 400 after sliding.
[0055] Furthermore, the base 100 has a plurality of positioning holes 120 , and the top plate 300 has an inserting portion 310 . After the inserting portion 310 enters the positioning hole 120 , the inserting portion 310 is used to fix the top plate 300 .
[0056] In this embodiment, the top plate 300 has a plug-in portion 310, which can enter and leave the positioning hole 120. After the plug-in portion 310 enters the positioning hole 120, the top plate 300 can be fixed at a certain position. The operator can adjust the position of the top plate 300 and change the distance between the top plate 300 and the cutting knife 400 by inserting the plug-in portion 310 into different positioning holes 120, thereby flexibly adjusting the cutting length of the oil-immersed petroleum packing.
[0057] Furthermore, the top plate 300 has a top 320 and a clamping portion 330 . The top 320 is used to contact the front end of the oil-impregnated asbestos. The clamping portion 330 and the second section 222 are used to clamp the front end of the oil-impregnated asbestos. The clamping portion 330 and the top 320 have a certain angle.
[0058] In this embodiment, the top plate 300 includes a top portion 320 and a clamping portion 330. The top portion 320 can abut against the front end of the oil-impregnated asbestos to ensure the cutting length of the oil-impregnated asbestos. The clamping cloth can work with the second portion 222 from the side to clamp and secure the front end of the oil-impregnated asbestos, preventing the front end of the oil-impregnated asbestos from curling and affecting cutting accuracy.
[0059] Furthermore, after the cutting blade 400 rotates, the side surface of the cutting blade 400 abuts against the inner wall of the first groove 110 close to the sliding plate 230 .
[0060] In this embodiment, after the cutting knife 400 rotates, the side surface of the cutting knife 400 abuts against the inner wall of the first groove 110 close to the sliding plate 230, so that the cutting knife 400 and the base 100 can act together on the oil-impregnated petroleum packing, and use the shear force to cut off the oil-impregnated asbestos, which is beneficial to improving the cutting accuracy and end face quality of the oil-impregnated asbestos.
[0061] Furthermore, the base 100 has a second groove 130, which is located on the side of the cutting knife 400 away from the top plate 300, and the second groove 130 is located on the side of the fixed plate 220 close to the sliding plate 230, and also includes a magnet 600 arranged in the second groove 130, and the magnet 600 is used to adsorb and fix the sliding plate 230.
[0062] In this embodiment, the magnet 600 is placed in the second groove 130 of the base 100 , and the magnet adsorbs and fixes the sliding plate 230 , making it convenient for an operator to move and fix the sliding plate 230 .
[0063] The magnet 600 is placed in the second groove 130 of the base 100 , which can prevent the magnet 600 from affecting the oil-impregnated asbestos from passing through the clamping space 210 .
[0064] Furthermore, the base 100 has a plurality of slide grooves 140 , and the direction of the slide grooves 140 is parallel to the direction of the first groove 110 . The sliding plate 230 has a plurality of limiting portions 234 , and the limiting portions 234 are slidably disposed in the slide grooves 140 .
[0065] In this embodiment, the slide groove 140 has a limiting effect on the sliding direction of the sliding plate 230. During the sliding process of the sliding plate 230, the slide groove 140 can ensure that the inclined surface 233 of the first end 231 of the sliding plate 230 is always parallel to the inner wall of the first groove 110.
[0066] The grooves can ensure the parallelism between the sliding plate 230 and the fixing plate 220, and ensure the stable fixation of the oil-impregnated asbestos.
[0067] Furthermore, a first handle 410 is provided at one end of the cutting blade 400 away from the rotation axis of the cutting blade 400 ; and a second handle 510 is provided at one end of the rotating pressing plate 500 away from the rotation axis of the rotating pressing plate 500 .
[0068] In this embodiment, the first handle 410 and the second handle 510 improve the convenience of operation for the operator.
