Description

Technical Field

[0001] The present application relates to the technical field of cutting devices, and in particular to a carbon-to-carbon cutting device. Background Art

[0002] Carbon-carbon composites (carbon fiber reinforced carbon matrix composites) have a series of advantages such as high strength and modulus, low thermal expansion coefficient, good thermal properties and good toughness, and still have excellent physical and chemical properties under high temperature environment. As high-temperature fasteners, battery terminal carriers, thermal insulation materials, etc., the demand is becoming more and more extensive, and various new problems will be encountered during the processing.

[0003] Traditional carbon-carbon composite material processing methods often rely on the coordinated use of sawing machines and lathes. In the early stage, they mainly rely on manual cutting, which is not only inefficient but also easy to cause material waste. For large-sized plates, although engraving machines can achieve relatively precise processing, their processing speed is relatively slow and it is difficult to meet the needs of large-scale production.

[0004] At present, although there have been some studies on carbon-carbon material cutting devices, most of them focus on the cutting of low-density thermal insulation felt products. For high-density carbon-carbon products, due to their special physical properties, the problems in the cutting process are more complicated, and there are relatively few related patents and technologies. For example, the thermal insulation felt cutting device described in patent number CN220261144U, although compared with manual cutting, has improved efficiency and end surface flatness, it is mainly suitable for the processing of small-sized products. When facing large products, the shaking of the saw blade is easy to cause cutting defects, thus affecting product quality. Another cutting device with patent number CN219768333U, although it solves the problem of tool shaking to a certain extent, its tool is fixed at the top and moves with the movement of the main bracket of the cutting device. For the cutting of large products, it is still necessary to extend the saw blade, the shaking problem of the saw blade still exists, and the operation is inconvenient. Therefore, for high-density carbon-carbon composite materials, especially the cutting and processing of large products, it is still necessary to develop more efficient, accurate and stable cutting devices and technologies to meet the growing market demand.

[0027] The following combination Figure 1-2 A carbon-carbon cutting device provided in an embodiment of the present application is introduced, which can be used for cutting carbon-carbon material bodies such as brake discs, brake pads, seals, brush materials, nozzles, thermal insulation felts, etc. The carbon-carbon cutting device includes a workbench 1, two columns 2 are arranged in parallel on both sides of the workbench 1, and a support beam 3 is arranged between the two columns 2 and can move linearly along the columns 2; a cutting assembly 4 is arranged on the support beam 3, and the cutting assembly 4 includes a driving assembly 41 and a band saw blade 42, and the driving assembly 41 includes a driving wheel 411 and a driven wheel 412 arranged at both ends of the support beam 3 at intervals, and the driving wheel 411 is used to rotate and drive the band saw blade 42 and the driven wheel 412 to rotate.

[0028] Specifically, the band saw blade 42 is arranged between the driving wheel 411 and the driven wheel 412. The band saw blade 42 is installed around the driving wheel 411 and the driven wheel 412. By adjusting the distance between the two wheels, the band saw blade 42 is tightened. The band saw blade 42 is driven by the rotation of the driving wheel 411 and transmitted to the driven wheel 412, so that the band saw blade 42 can be unidirectionally cyclically and rapidly rotated for cutting. In the embodiment of the present application, a workbench 1 and two columns 2 are arranged, and a support beam 3 that can move linearly along the columns 2 is arranged between the columns 2. The cutting assembly 4 is arranged on the support beam 3, so that the cutting assembly 4 can flexibly adjust its position to meet the cutting requirements of carbon-carbon materials of different sizes, thereby improving the adaptability and flexibility of the device. The band saw blade 42 is driven by the driving wheel 411 and the driven wheel 412 to cyclically rotate and cut, thereby improving the cutting efficiency and cutting stability.

[0029] In some possible implementations, the drive assembly 41 includes a drive motor 413, and the drive end of the drive motor 413 is used to connect to the driving wheel 411 to drive the driving wheel 411 to rotate. In practical applications, the drive motor 413 and the driving wheel 411 can be connected by a coupling. By setting the drive motor 413 to be connected to the driving wheel 411, the function of automatically driving the band saw blade 42 to rotate is realized, thereby improving the cutting efficiency.

[0030] Specifically, in the embodiment of the present application, the two ends of the band saw blade 42 are closed and connected, and a plurality of evenly arranged sawtooth segments are provided on one side of the band saw blade 42.

The longer the length of the band saw blade 42, the larger the product that can be cut, but the longer the length, the easier it is for the band saw blade to shake, and the shaking will cause an uneven cut surface. The guide mechanism 31 of the present application is used to maintain the stability of the band saw blade 42 during the cutting process, improve the flatness of the cutting surface, and improve the cutting accuracy. At the same time, the setting of the guide mechanism 31 is also conducive to extending the service life of the band saw blade 42.

[0033] Specifically, the saw blade guide 32 includes at least two clamping guide wheels 321 arranged in parallel, and a guide gap is provided between the two clamping guide wheels 321 for the band saw blade 42 to pass through. The arrangement of the two clamping guide wheels 321 and the guide gap enables the band saw blade 42 to pass through smoothly and keeps the running track of the band saw blade 42 accurate and stable.

[0034] In some possible embodiments, two clamping guide surfaces 322 are arranged in parallel between the two clamping guide wheels 321, and a guide gap is provided between the two clamping guide surfaces 322 for the band saw blade 42 to pass through. The clamping guide surface 322 can be the outer surface of a cylindrical body or. The contact area between the clamping guide wheel 321 and the band saw blade 42 is small, and the provision of the clamping guide surface 322 can further improve the stability of the band saw blade 42 during the cutting process, and improve the flatness of the cutting surface and the cutting accuracy.

[0035] In some possible implementations, a clamping wheel (not shown) is provided at one end of the clamping guide wheel 321, and the outer surface of the clamping wheel contacts the side of the band saw blade 42 away from the sawtooth segment. The surface of the clamping wheel contacts and presses the side of the band saw blade 42, further improving the stability of the band saw blade 42, preventing the band saw blade 42 from moving left and right, and reducing vibration and deviation during the cutting process.

[0036] In the embodiment of the present application, two relatively movable guide mechanisms 31 are provided on the support beam 3. In some possible implementations, at least two spaced-apart guide mechanisms 31 are connected to the support beam 3 so as to be relatively movable.

[0037] In some possible embodiments, a side of the support beam 3 connected to the guide mechanism 31 is provided with a plurality of connection structures connected to the guide mechanism 31.

In some possible embodiments, a connection matching structure matched with the connection structure is provided on the guide mechanism 31, and the position of the guide mechanism 31 can be adjusted by matching the connection matching structure on the guide mechanism 31 with the connection structures at different positions. In some possible embodiments, the connection structure can be a plurality of connection holes provided on the support beam 3, and the connection matching structure can be a threaded structure provided at one end of the guide mechanism 31, and the threaded structure is screwed with the connection hole. In other possible embodiments, the connection structure can be a connection groove provided on the support beam 3, and the connection matching structure can be a connection block provided at one end of the guide mechanism 31, and the connection groove is connected with the connection block by interference or matching.

In practical applications, multiple connection structures are provided to facilitate the installation and disassembly of the guide mechanism 31, thereby improving the maintenance convenience of the device. The guide mechanism 31 can be moved according to the size of the product to be cut, and the band saw blade 42 can be fixed to suppress the occurrence of shaking.

[0038] Specifically, at least one column 2 is provided with a lifting drive assembly 5, and the lifting drive assembly 5 includes a lifting screw 51 and a moving block, the moving block is slidably connected to the lifting screw 51, and the moving block is fixedly connected to the support beam 3. In practical applications, the lifting drive assembly 5 includes a lifting motor 53, and the lifting motor 53 drives the lifting screw 51 to rotate, and the lifting screw 51 drives the moving block to slide along the lifting screw 51 through the screw nut, thereby driving the support beam 3 to move linearly along the column 2. In some possible embodiments, the two parallel columns 2 are both provided with a lifting drive assembly 5 to drive the support beam 3 to move up and down along the column 2. In other possible embodiments, one of the columns 2 is provided with a lifting drive assembly 5, and the other column is provided with a sliding guide rail, and the support beam 3 is provided with a guide rail matching structure matching with the sliding guide rail. When the lifting drive assembly 5 drives the support beam 3 to move along one column 2, the other end of the support beam 3 moves linearly along the other column 2 synchronously. A lifting drive assembly 5 is arranged on the column 2 of the present application, and the lifting function of the support beam 3 is realized through the lifting screw rod 51 and the moving block, so that the cutting assembly can adapt to the cutting requirements of carbon-carbon materials at different heights, increase the flexibility of the cutting product height, and further improve the adaptability and flexibility of the device.

[0039] Specifically, in the embodiment of the present application, the cutting device further comprises a base 6, on which a translation drive assembly 7 is provided, and the translation drive assembly 7 comprises a translation screw 71, a slider and a translation guide rail 73 arranged on the base 6. In practical applications, the translation drive assembly 7 comprises a translation motor 74, which drives the translation screw 71 to rotate, and drives the driving slider to slide relative to the translation screw 71 through the screw nut, and the driving slider is fixedly connected to the workbench 1. The workbench 1 is slidably connected to the translation guide rail 73, and the translation screw 71 is used to rotate the driving slider to drive the workbench 1 to move along the translation guide rail 73. The present application drives the workbench 1 to move horizontally through the translation drive assembly 7, so that the entire product to be cut can be easily moved. During cutting, the moving speed of the workbench 1 can be controlled by the translation drive assembly 7, and then the cutting feed amount can be adjusted. When the product density is large, the speed can be slowed down, and when the density of the cutting product is small, the speed can be increased, thereby improving the stability of the movement of the workbench 1 and the cutting accuracy.

[0040] In some possible embodiments, the column 2 is integrally formed with the base 6. In other possible embodiments, the column 2 is fixedly connected to the base 6 by welding, clamping or bolting. The design of the column 2 and the base 6 being integrally formed allows a seamless connection between the column and the base, avoiding the problem of loose connection or gap that may exist in the traditional split design. This compact structure allows the entire device to have higher stability and strength when bearing loads, ensuring the long-term stable operation of the cutting device.
