Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon fiber bicycle frame processing, specifically a cutting device for processing carbon fiber bicycle frames. Background Technology
[0002] Carbon fiber bicycles are a new type of bicycle made with carbon fiber composite materials as the core frame material. Their core advantage comes from the properties of carbon fiber itself, which has both extremely high tensile strength and extremely low density. Compared with traditional aluminum alloy, steel and other metal frames, carbon fiber frames can reduce weight by more than 30% while achieving the same or even higher structural strength. This can significantly reduce inertial resistance during riding and improve acceleration performance and range efficiency.
[0003] In the production and modification of carbon fiber bicycles, the cutting and processing of carbon fiber frames is one of the key processes. In later modification or repair scenarios, such as adjusting the frame geometry to fit riders of different heights or repairing damaged frame tubes, it is necessary to cut the already formed carbon fiber frame locally.
[0004] However, the process of cutting rectangular tube frame tubes made of carbon fiber generates carbon fiber dust and fiber fragments. These carbon fiber dust particles are small and lightweight, making them extremely easy to float and diffuse in the air. They are difficult to remove quickly through natural settling, resulting in a continuous increase in dust concentration in the air environment of the cutting work area. Once inhaled by operators, they are not only difficult to be broken down and excreted by metabolic organs such as the liver and kidneys, but in severe cases, they can even cause irreversible damage to lung function, posing a significant threat to the health of operators. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a cutting device for processing carbon fiber bicycle frames, so as to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for processing carbon fiber bicycle frames, comprising a cutting seat, a cutting groove provided inside the top of the cutting seat, inner cavities provided on both sides of the cutting groove, an outer ring and a limiting ring respectively installed in the two sets of inner cavities, an outer tube provided at one end of the outer ring, an inner ring installed inside the outer ring, an inner tube connected to one end of the inner ring, a moving groove provided at the top of the inner wall of the limiting ring, an extrusion plate installed inside the moving groove, a connecting plate movably arranged inside the extrusion plate, a threaded rod fixed at the top of the connecting plate, an adjusting head connected to the top of the threaded rod, and a carbon tube placed inside the limiting ring.
[0007] By adopting the above technical solution, the problem of personnel easily inhaling carbon fiber dust during the cutting of carbon fiber frame tubes is solved. Before cutting the carbon tube, the extension tube of the vacuum cleaner is first fitted onto the outer tube, and the extension tube of the vacuum cleaner is wrapped and sealed with a soft sleeve. Then the carbon tube is inserted into the cutting seat and fixed. During the cutting process, the suction force generated by the vacuum cleaner sucks up the dust floating inside the cutting groove and carbon tube through the outer and inner sleeves, avoiding a large amount of carbon fiber dust floating in the indoor environment.
[0008] The present invention is further configured such that a connecting ring is fixed to the outer wall of the outer tube, a soft pouch is fixed to one end of the connecting ring, a drawstring is provided at one end of the soft pouch, and a tightening rope is installed inside the drawstring.

[0010] The present invention is further configured such that four sets of connecting blocks are fixed on the outer wall of the inner sleeve, and the connecting blocks are triangular, with one end of the connecting block having an arc shape.
[0011] Preferably, the inner ring is fixed inside the outer ring by four sets of connecting blocks, and the rounded ends of the connecting blocks can prevent carbon fiber dust from being blocked inside the outer ring due to the obstruction of the connecting block walls.
[0012] The present invention is further configured such that the inner wall size of the outer ring is larger than the outer wall size of the carbon tube, and the inner wall diameter of the outer ring is 4mm larger than the outer wall diameter of the carbon tube.
[0013] Preferably, when the carbon tube is inserted into the cutting seat, there is a certain gap between the carbon tube and the inner wall of the outer ring, so that the dust generated by cutting the carbon tube can flow along the gap into the outer tube.
[0014] The present invention is further configured such that the outer wall dimension of the inner ring is smaller than the inner wall dimension of the outer ring, and the inner wall dimension of the inner ring is larger than the inner wall dimension of the carbon nanotube.
[0015] Preferably, when one side of the inner ring contacts the carbon tube wall, the vacuum cleaner can draw dust floating in the inner wall of the carbon tube into the inner tube through the inner tube and the inner ring.
[0016] The present invention is further configured such that four sets of fixing blocks are fixed to the outer wall of the outer sleeve, and the fixing blocks are neodymium iron boron magnets, and the outer wall size and shape of the four sets of fixing blocks match the size and shape of the inner cavity wall.
[0017] Preferably, when the operator inserts the carbon tube into the inner cavity of the cutting seat, the operator can adjust the position of the outer sleeve inside the iron cutting seat by pushing the outer tube exposed outside the cutting seat, so that one side wall of the inner sleeve contacts one end wall of the carbon tube, allowing the carbon fiber dust inside the carbon tube to flow into the inner tube through the inner sleeve.
[0018] The present invention is further configured such that a cavity is provided inside the bottom end of the cutting seat, a collection box is installed inside the cavity, and the cutting groove is connected to the cavity.
[0019] Preferably, the fiber fragments generated from cutting the carbon nanotubes fall downwards into the cavity due to their excessive weight, and a collection box installed inside the cavity collects the fiber fragments.
[0020] The present invention is further configured such that the inner wall of one side of the outer ring and the limiting ring is inclined, and the wall of the channel port connecting the bottom of the cutting groove and the cavity is inclined.
[0021] Preferably, during the process of fiber fragments falling, the fiber fragments can fall into the cavity along the channel port of the inclined wall connected to the bottom of the cutting groove.
[0022] The present invention is further configured such that the inner diameter of the drawstring ring is larger than the outer diameter of the vacuum cleaner extension tube, the width of the drawstring ring is larger than the radius of the soft pouch, and the tightening cord is installed at one end of the drawstring ring.
[0023] Preferably, when the vacuum cleaner extension tube is inserted into the soft sleeve, the user can pull the tightening cord to shrink one end of the tubular retaining ring and wrap it around the outer wall of the vacuum cleaner extension tube, thereby reducing the flow of external air into the soft sleeve.
[0024] In summary, the present invention has the following main advantages: This invention solves the problem of personnel easily inhaling carbon fiber dust during the cutting of carbon fiber frame tubes by setting up a cutting seat, outer ring, inner ring, soft sleeve, limiting ring, and extrusion plate. Before cutting the carbon tube, the personnel first attach the extension tube of the vacuum cleaner to the outer tube and wrap and seal the extension tube with the soft sleeve. Then, the carbon tube is inserted into the cutting seat and fixed. During the cutting process, the suction force generated by the vacuum cleaner draws out the dust floating in the cutting groove and inside the carbon tube through the outer ring and inner ring, preventing a large amount of carbon fiber dust from floating in the indoor environment.
[0025] This invention, by setting up a cutting seat, an inner cavity, an outer ring, and a fixing block, allows personnel to push and adjust the outer ring inside the cutting seat by means of the outer tube exposed outside the cutting seat during the process of inserting the carbon tube into the inner cavity. This makes one side wall of the inner ring contact one end wall of the carbon tube, allowing the carbon fiber dust inside the carbon tube to flow into the inner tube through the inner ring.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0029] The embodiments of this utility model will be described below based on its overall structure.
[0030] Please see Figure 1 — Figure 8The device includes a cutting seat 1, with a cutting groove 101 inside the top of the cutting seat 1. Both sides of the cutting groove 101 have inner cavities 102. An outer ring 2 and a limiting ring 4 are respectively installed in the two sets of inner cavities 102. An outer tube 201 is provided at one end of the outer ring 2, and an inner ring 202 is installed inside the outer ring 2. One end of the inner ring 202 is connected to an inner tube 203. A moving groove 401 is provided at the top of the inner wall of the limiting ring 4. An extrusion plate 5 is installed inside the moving groove 401. A connecting plate 502 is movably arranged inside the extrusion plate 5. A threaded rod 501 is fixed to the top of the connecting plate 502. The end is connected to an adjustment head 503, and a carbon tube 6 is placed inside the limiting ring 4. This solves the problem that personnel are prone to inhaling carbon fiber dust during the cutting of carbon fiber frame tubes. Before cutting the carbon tube 6, the personnel first put the extension tube of the vacuum cleaner onto the outer tube 201 and wrap and seal the extension tube of the vacuum cleaner with the soft sleeve 3. Then, the carbon tube 6 is inserted into the cutting seat 1 and fixed. During the cutting of the carbon tube 6, the suction force generated by the vacuum cleaner sucks out the dust floating inside the cutting groove 101 and the carbon tube 6 through the outer ring 2 and the inner ring 202, avoiding a large amount of carbon fiber dust floating in the indoor environment.
[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A connecting ring 303 is fixed to the outer wall of the outer tube 201. A soft pouch 3 is fixed to one end of the connecting ring 303. A drawstring 301 is provided at one end of the soft pouch 3. A tightening rope 302 is installed inside the drawstring 301. When the soft pouch 3 is wrapped around the extension tube of the vacuum cleaner, the soft pouch 3 can seal the extension tube of the vacuum cleaner and the outer tube 201, making full use of the suction effect of the vacuum cleaner.
[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 5 The inner ring 202 has four sets of connecting blocks 204 fixed on its outer wall. The connecting blocks 204 are triangular and have a rounded end. The inner ring 202 is fixed inside the outer ring 2 by the four sets of connecting blocks 204. The rounded end of the connecting blocks 204 can prevent carbon fiber dust from being blocked inside the outer ring 2 due to the obstruction of the wall of the connecting blocks 204.
[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 8 The inner wall size of the outer ring 2 is larger than the outer wall size of the carbon tube 6, and the inner wall diameter of the outer ring 2 is 4mm larger than the outer wall diameter of the carbon tube 6. When the carbon tube 6 is inserted into the cutting seat 1, there is a certain gap between the carbon tube 6 and the inner wall of the outer ring 2, so that the dust generated by cutting the carbon tube 6 can flow along the gap into the outer tube 201.
[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 8 The outer wall size of the inner ring 202 is smaller than the inner wall size of the outer ring 2, and the inner wall size of the inner ring 202 is larger than the inner wall size of the carbon tube 6. When one side of the inner ring 202 contacts the wall of the carbon tube 6, the vacuum cleaner can suck the dust floating in the inner wall of the carbon tube 6 into the inner tube 203 through the inner tube 203 and the inner ring 202.
[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 The outer wall of the outer ring 2 is fixed with four sets of fixing blocks 205, and the fixing blocks 205 are neodymium iron boron magnets. The size and shape of the outer wall of the four sets of fixing blocks 205 match the size and shape of the inner cavity 102 wall. When the personnel insert the carbon tube 6 into the inner cavity 102 inside the cutting seat 1, the personnel can adjust the position of the outer ring 2 inside the iron cutting seat 1 by pushing the outer tube 201 exposed outside the cutting seat 1, so that one side wall of the inner ring 202 contacts one end wall of the carbon tube 6, so that the carbon fiber dust inside the carbon tube 6 can flow into the inner tube 203 through the inner ring 202.
[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 8 The bottom of the cutting seat 1 has a cavity 103, and a collection box 104 is installed inside the cavity 103. The cutting groove 101 is connected to the cavity 103. When the carbon tube 6 is cut, the fiber fragments produced fall into the cavity 103 due to their excessive weight. The collection box 104 installed inside the cavity 103 collects the fiber fragments.
[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 , Figure 6 and Figure 8 The inner wall of the outer ring 2 and the limiting ring 4 is inclined on one side, and the channel port wall of the bottom of the cutting groove 101 connected to the cavity 103 is inclined. When the fiber fragments fall, the fiber fragments can fall into the cavity 103 along the channel port of the inclined wall connected to the bottom of the cutting groove 101.
[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The inner diameter of the drawstring 301 is larger than the outer diameter of the vacuum cleaner extension tube, and the width of the drawstring 301 is larger than the radius of the soft sleeve 3. The tightening rope 302 is installed at one end of the drawstring 301. When the vacuum cleaner extension tube is inserted into the soft sleeve 3, the user can pull and tighten the tightening rope 302 to shrink one end of the tubular drawstring 301 and wrap it around the outer wall of the vacuum cleaner extension tube, reducing the flow of external air into the soft sleeve 3.
[0039] In practical operation, before cutting the rectangular carbon tube 6, the extension tube connecting the vacuum cleaner main unit and the nozzle is inserted into the TPE soft sleeve 3, so that the extension tube is sleeved on the end of the outer tube 201. Then, the operator pulls the rope 302 tightly so that the drawstring 301 tightens and wraps the end of the soft sleeve 3 around the outer wall of the vacuum cleaner's extension tube. The operator then inserts the carbon tube 6 into the cutting seat 1 through the port 102 of the inner cavity on one side, so that the end of the carbon tube 6 contacts one side wall of the inner ring 202 inside the cutting seat 1. Then, the operator inserts the iron rod into the through hole at the top of the adjusting head 503 and rotates the adjusting head 503. Since the threaded rod 501 fixed at the bottom of the adjusting head 503 is connected to the inside of the cutting seat 1 by threads, the threaded rod 501 pushes the extrusion plate 5 downward, and the extrusion plate 5 is always in the moving groove 401 in the inner wall of the limiting ring 4. The extrusion plate 5 moves vertically, and when the extrusion plate 5 fixes the carbon tube 6 in place by extrusion, the operator turns on the vacuum cleaner and inserts the cutting saw into the cutting groove 101 to cut the carbon tube 6. During the cutting of the carbon tube 6, the extension tube of the vacuum cleaner sucks up the carbon fiber dust floating in the cutting groove 101 and inside the carbon tube 6 through the outer tube 201 and the inner tube 203, respectively. The fiber fragments fall downwards into the collection box 104 inside the cavity 103 due to their excessive weight.
