Description

Technical Field

[0001] The utility model relates to the technical field of sand wire processing, and more specifically to a wire cutting machine. Background Art

[0002] Carbon-carbon composite materials are widely used in high-temperature environments, aerospace, military and automotive industries due to their low density, high temperature resistance, low thermal expansion coefficient, low thermal conductivity and the characteristics of their mechanical properties increasing with increasing temperature. When processing carbon-carbon composite materials, wire cutting machines loaded with annular diamond wires are often used for high-speed rotary cutting.

[0003] Since the application fields of carbon-carbon composite materials (such as photovoltaics and semiconductors) have extremely high requirements for product purity, impurities need to be removed through a purification process. This purification process will affect the size of the product, so the machining process, especially the cutting process using a wire cutter, must be performed after the purification process. However, in order to avoid contaminating the purified product, traditional cooling cutting fluids cannot be used on wire cutters, which causes the emery wire to overheat easily during use, thereby accelerating its wear rate, far exceeding the loss of traditional wire cutting. Therefore, when using traditional wire cutters to process carbon-carbon composites, the consumption of emery wire is abnormally high, which increases costs, and the service life of the emery wire is significantly reduced due to overheating problems.

[0004] Therefore, how to improve the wire cutting machine to extend the service life of the diamond wire when processing carbon-carbon composite materials has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0030] The core of the utility model is to disclose a wire cutting machine to extend the service life of the diamond wire when processing carbon-carbon composite materials.

[0031] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0032] Combination Figure 1 The wire cutting machine disclosed in the embodiment of the utility model includes a frame 4, an annular emery wire 2, a water cooling device 6 and a moisture removal device 5. The frame 4 is provided with a workbench 3 for placing the workpiece to be cut, and a cutting position is formed at the workbench 3; the annular emery wire 2 is an annular structure connected end to end, and is rotatably arranged on the frame 4, and the annular emery wire 2 extends to the cutting position, and can cut the workpiece to be cut at the cutting position. The water cooling device 6 contains cooling water, and the cooling water is pure water. The annular emery wire 2 extends to below the cooling water surface in the water cooling device 6 and can be cooled. The moisture removal device 5 is used to remove moisture on the surface of the annular emery wire 2 after cooling. Along the rotation direction of the annular emery wire 2, the annular emery wire 2 passes through the cutting position, the water cooling device 6 and the moisture removal device 5 in sequence and returns to the cutting position, so that when the annular emery wire 2 is heated by cutting the workpiece to be cut at the cutting position, it can enter the water cooling device 6 and be directly cooled by cooling water. The cooling water adhered to the surface of the cooled annular emery wire 2 can be removed by the moisture removal device 5, and the annular emery wire 2 that returns to the cutting position again can be maintained at a lower temperature.

[0033] In the specific implementation process, after the workpiece to be cut is placed on the workbench 3, the workpiece to be cut can be cut by pushing the workpiece to be cut toward the high-speed rotating annular emery wire 2. After passing the cutting position, the frictionally heated annular emery wire 2 is rotated into the water cooling device 6 for cooling, and then passes through the moisture removal device 5 to remove the moisture adhered to the surface, and finally returns to the cutting position again to cut the workpiece to be cut.

[0034] Compared with the prior art, the wire cutting machine disclosed in the embodiment of the utility model is provided with a water cooling device 6 and a moisture removal device 5 on the rotation path of the annular emery wire 2, which can effectively reduce the cutting temperature of the annular emery wire 2, and the cooling water can be removed, avoiding the influence on the purity of the carbon-carbon composite material, and can effectively extend the service life of the annular emery wire 2 when processing the carbon-carbon composite material, thereby reducing the production cost.

[0035] It is understandable that the cooling water is pure water, does not contain impurities, and can be removed by drying or wiping without leaving any residue.

[0036] Specifically, the moisture removal device 5 is provided with a moisture removal channel, and the annular diamond wire 2 passes through the moisture removal channel, and moisture is removed during the passing process.

[0037] For example, when the moisture removal device 5 is an oven or a fan, the moisture removal device 5 can spray drying gas onto the annular diamond wire 2 in the moisture removal channel to remove moisture.

[0038] When the moisture removal device 5 is an oven, the oven can be specifically provided with a moisture removal channel having openings passing through both ends, and the annular diamond wire 2 can be installed into the moisture removal channel through the openings.

[0039] An invisible moisture removal channel is formed on the blowing path of the fan, and the blowing path of the fan can be conveniently adjusted to face the annular emery wire 2 by adjusting the orientation of the fan.

[0040] Preferably, the temperature of the drying gas sprayed by the moisture removal device 5 is lower than 50°C, and more preferably lower than 40°C.

[0041] In a specific embodiment disclosed in the utility model, the moisture removal device 5 includes multiple layers of water-absorbing layers made of water-absorbing materials, and a moisture removal channel is formed between two adjacent layers of water-absorbing layers. The annular diamond wire 2 passes through the two adjacent layers of water-absorbing layers, and the water on the surface is absorbed by the water-absorbing layers. The water-absorbing layer can be specifically absorbent paper or absorbent cloth, etc., and is detachably fixed to the frame 4 through a connecting piece (for example, fixed by tying with ropes, cable ties, etc.), so that it can be replaced at any time.

[0042] Correspondingly, a humidity detection sensor can be provided on the moisture removal device 5 or the rack 4 to monitor at any time whether the water absorbing layer needs to be replaced. The humidity detection sensor can be a direct contact type or an indirect contact type according to actual conditions.

[0043] The rotation of the annular emery wire 2 is realized by the guide wheel 1. Specifically, a plurality of guide wheels 1 are rotatably arranged on the frame 4. The guide wheels 1 form a rotation path of the annular emery wire 2. The annular emery wire 2 cooperates with each guide wheel 1 and rotates synchronously. One of the guide wheels 1 is used as a driving wheel to be driven and rotated by the driving device, thereby driving the annular emery wire 2 to rotate. The remaining guide wheels 1 are used as follower wheels to rotate with the rotation of the annular emery wire 2 to achieve the cutting of the annular emery wire 2.

[0044] At least one guide wheel 1 is arranged in the water cooling device 6 and is located below the surface of the cooling water. The annular diamond wire 2 can be wound into the cooling water and cooled along with the arrangement of the guide wheel 1. Figure 1 As shown, the two guide wheels 1 are both arranged under the surface of the cooling water, which effectively prolongs the cooling time of the annular emery wire 2 .

[0045] The guide wheel 1 is detachably arranged on the frame 4 , and the guide wheel 1 located below the surface of the cooling water can also be directly detachably arranged on the inner wall of the water cooling device 6 .

[0046] In order to enhance the effect of removing moisture from the surface of the annular diamond wire 2, the moving path of the annular diamond wire 2 in the moisture removal channel can be extended. Figure 2 As shown, a plurality of freely rotatable steering wheels 7 can be provided on the moisture removal device 5, and the steering wheels 7 are provided in the moisture removal channel. The portion of the annular emery wire 2 located in the moisture removal channel is wound in cooperation with each steering wheel 7, which can effectively extend the moving path of the annular emery wire 2 in the moisture removal channel, thereby extending the moisture removal time and enhancing the moisture removal effect. Moreover, the steering wheels 7 can rotate with the rotation of the annular emery wire 2, and the wear on the annular emery wire 2 is small.

[0047] Each steering wheel 7 can be arranged on the same straight line, preferably, as Figure 2 As shown, the steering wheels 7 are not arranged on the same straight line, so as to effectively extend the moisture removal path of the annular emery wire 2 .

[0048] In a specific embodiment, the water cooling device 6 is a container structure with an open mouth, and is used to be arranged on the ground or on the frame 4, and the annular diamond wire 2 enters and exits the water cooling device 6 through the open mouth. The moisture removal device 5 can be arranged on the frame 4.

[0049] In order to ensure the normal operation of the wire cutting machine, a tensioning device is also provided on the frame 4 , which can tension the annular emery wire 2 and ensure the cutting effect of the annular emery wire 2 .

[0050] In addition, the water cooling device 6 may be directly replaced by an air cooling device (such as a fan) to cool the annular diamond wire 2 , and accordingly, the water removal device 5 may be eliminated.

[0051] The above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. The specific technical means in some embodiments can be combined in part or in whole into another embodiment without being explicitly excluded by another embodiment. Therefore, the utility model will not be limited to the embodiments shown in this article, but will conform to the widest range consistent with the principles and novel features disclosed herein.
