[0019] like Figure 1 and Figure 2 As shown, an embodiment of the present invention proposes a processing device 100 for an annular high-temperature thermal insulation cloth, the processing device 100 for annular high-temperature thermal insulation cloth comprises a base 10 and a cutter 20, a groove 11 is provided at the bottom of the base 10, the edge of the groove 11 is configured as a flange 12, the flange 12 is used to contact with the high-temperature thermal insulation cloth to press the high-temperature thermal insulation cloth, the cutter 20 comprises a main body 21 and an annular blade 22 connected to the bottom of the main body 21, the main body 21 is rotatably installed in the base 10 by a threaded connection, the annular blade 22 is configured to be able to extend into the groove 11 and abut against the high-temperature thermal insulation cloth to rotate and cut the high-temperature thermal insulation cloth.

[0020] It should be understood that the operating temperature range of high temperature insulation cloth is 100°C to 350°C.

[0021] In the processing device 100 of the annular high-temperature insulation cloth proposed in the embodiment of the present invention, the base 10 is used to install the tool 20 and to press the high-temperature insulation cloth. The bottom of the base 10 is provided with a groove 11 to limit and accommodate the part of the high-temperature insulation cloth to be cut, and the flange 12 of the groove 11 is used to press the high-temperature insulation cloth to ensure that the subsequent tool 20 can cut smoothly; the main body 21 of the tool 20 is threadedly connected to the base 10, and the main body 21 rotates relative to the base 10, while driving the annular blade 22 connected to the bottom to rotate and generate vertical movement at the same time, so that the annular blade 22 can cut the high-temperature insulation cloth during the movement. The processing device 100 of the annular high-temperature insulation cloth proposed in the embodiment of the present invention has a compact structure, and the annular blade 22 cooperates with the flange 12 of the base 10, which can stably and quickly cut the annular high-temperature insulation cloth, improve the processing efficiency and processing accuracy, and solve the problems of low processing efficiency and poor processing accuracy in the prior art.

[0022] Furthermore, the base 10 may be shaped like a column or a cube, which is not specifically limited in this embodiment. Figure 1 and Figure 2 , and refer to Figure 3 and Figure 4 The base 10 is set to a cylindrical shape, and a groove 11 is set at the bottom of the base 10. The groove 11 can be formed at the bottom of the base 10 by an integrated molding method. The cross-sectional shape of the groove 11 can be set to a circular, elliptical or rectangular shape according to actual conditions. In this embodiment, the groove 11 is set to a circular groove 11, and accordingly, the flange 12 formed by the edge structure of the groove 11 is set to a circular flange 12. This setting method enables the flange 12 to evenly press the high-temperature insulation cloth, thereby improving the stability of the high-temperature insulation cloth, reducing the possibility of warping of the high-temperature insulation cloth during the cutting process, and ensuring the smooth molding of the annular high-temperature insulation cloth.

[0023] Based on the above embodiment, the bottom of the flange 12 is provided with a chamfer 121, such as Figure 3 and Figure 4 As shown, the chamfer 121 can be provided on the inner side of the flange 12. It can be understood that the bottom of the flange 12 contacts the high-temperature heat insulation cloth and is used to press the high-temperature heat insulation cloth. The provision of the chamfer 121 in this embodiment can reduce the contact area between the flange 12 and the high-temperature heat insulation cloth. When the overall weight of the processing device remains unchanged, reducing the contact area between the flange 12 and the high-temperature heat insulation cloth can increase the pressure, thereby further improving the stability of the high-temperature heat insulation cloth, reducing the possibility of warping of the high-temperature heat insulation cloth during the cutting process, and ensuring the smooth forming of the annular high-temperature heat insulation cloth.

[0024] Furthermore, the shape of the main body 21 of the tool 20 can also be set to be cylindrical. In a possible implementation, as shown in FIG. Figure 2 , Figure 5 and Figure 6 As shown, the shape of the main body 21 is set to be a stepped shaft, and the main body 21 includes a threaded rod 211 and a smooth rod 212 connected to the top of the threaded rod 211. The diameter of the threaded rod 211 is greater than or equal to the diameter of the smooth rod 212. The threaded rod 211 and the smooth rod 212 can be connected by welding or integral molding.

[0025] For example, Figure 2 and Figure 6As shown, the base 10 is provided with a threaded hole along the axial direction, and the threaded hole is connected to the groove 11 at the bottom of the base 10. The diameter of the threaded rod 211 of the tool 20 body 21 is larger than the diameter of the smooth rod 212. When the tool 20 is installed on the base 10, the threaded hole of the base 10 cooperates with the threaded rod 211 of the tool 20 body 21. The smooth rod 212 of the tool 20 body 21 is located above the base 10. The annular blade 22 arranged at the bottom of the tool 20 body 21 can partially or completely extend into the groove 11 of the base 10 and can produce relative movement with the high-temperature insulation cloth. That is to say, the tool 20 can rotate relative to the base 10, and can realize vertical movement while rotating, so that the annular blade 22 at the bottom of the body 21 cuts the high-temperature insulation cloth pressed by the base 10 in a downward rotating manner.

[0026] Based on the above implementation, Figure 1 As shown, the processing device also includes a wrench 30, which is connected to the tool 20, so as to drive the tool 20 to rotate relative to the base 10. The wrench 30 can be used for manual operation or can be connected to an external automated machine to achieve automatic cutting of the tool 20. This embodiment does not specifically limit this. Figure 1 As shown, the wrench 30 is connected to the polished rod 212 of the tool body 21. The wrench 30 and the polished rod 212 can be set to be threaded, clamped, welded or connected by integral molding, which is not specifically limited in this embodiment.

[0027] Exemplarily, a threaded hole is provided through the smooth rod 212 along the vertical axis, and the wrench 30 includes two rod-shaped wrenches 30 arranged opposite to each other. The outer wall of the rod-shaped wrench 30 is provided with an external thread matching the threaded hole, so that the two rod-shaped wrenches 30 are respectively threadedly connected to the opposite sides of the smooth rod 212. The operator can drive the tool 20 to rotate by holding the two rod-shaped wrenches 30 at the same time, and the spacing between the two rod-shaped wrenches 30 can be adjusted, which is convenient for the operator to adjust according to actual conditions. In this embodiment, the rod-shaped wrench 30 is easy to operate, which further improves the processing efficiency of the processing device.

[0028] Furthermore, if Figure 2 , Figure 5 and Figure 6 As shown, the tool 20 includes an annular blade 22 for cutting the high-temperature insulation cloth. The annular blade 22 can be set at the bottom of the tool 20 body 21 by welding or integral molding. In some embodiments of the present invention, the annular blade 22 includes an inner ring blade 221 and an outer ring blade 222. The inner ring blade 221 is used to cut the inner circle of the annular high-temperature insulation cloth, and the outer ring blade 222 is used to cut the outer circle of the annular high-temperature insulation cloth.

[0029] On the basis of the above-mentioned embodiment, with the plane perpendicular to the axis of the main body 21 as the projection plane, the projection of the annular blade 22 can be a closed ring or an unclosed ring, that is, the inner ring blade 221 can be set as a closed circular blade, or it can be set as a circular blade ring composed of a plurality of arc blades arranged at intervals. Similarly, the outer ring blade 222 can be set as a closed circular blade, or it can be set as a circular blade ring composed of a plurality of arc blades arranged at intervals.

[0030] For example, please refer to Figure 2 , Figure 5 and Figure 6 , taking the plane perpendicular to the axis of the main body 21 as the cross section, the cross sections of the inner ring blade 221 and the outer ring blade 222 are both set to be closed circles, the outer ring blade 222 is connected to the outer edge of the bottom surface of the main body 21, the outer side surface of the blade end of the outer ring blade 222 is inclined inward, and the inner side surface is perpendicular to the high-temperature insulation cloth; the inner ring blade 221 is located inside the outer ring blade 222, the inner side surface of the blade end of the inner ring blade 221 is inclined outward, and the outer side surface is perpendicular to the high-temperature insulation cloth.

[0031] Further, in some embodiments of the present invention, Figure 6 As shown, from the direction of the main body 21 pointing to the annular blade 22, the blade end of the inner ring blade 221 exceeds the blade end of the outer ring blade 222, that is, in the process of the annular blade 22 gradually contacting the high-temperature insulation cloth as the main body 21 of the tool 20 rotates downward, the inner ring blade 221 contacts the high-temperature insulation cloth before the outer ring blade 222, that is, the inner ring blade 221 starts to cut the high-temperature insulation cloth first, and the inner circle of the annular high-temperature insulation cloth is formed before the outer circle. This setting method can prevent the problem caused by the outer circle being formed first, that is, after the outer ring blade 222 completes the cutting, the high-temperature insulation cloth rotates together with the outer ring blade 222, resulting in the inner ring blade 221 being unable to complete the cutting, thereby ensuring the processing efficiency and processing accuracy of the annular high-temperature insulation cloth.

[0032] Furthermore, based on the above embodiment, the distance difference between the blade end of the inner ring blade 221 and the blade end of the outer ring blade 222 can be any value between 0.1mm-0.5mm. Exemplarily, the distance difference between the blade end of the inner ring blade 221 and the blade end of the outer ring blade 222 is set to 0.3mm.

[0033] In some embodiments of the present invention, Figure 6As shown, the cutter 20 also includes an ejector pin 23, which is vertically connected to the bottom center of the main body 21, and the axis of the ejector pin 23 coincides with the axis of the main body 21. The bottom end of the ejector pin 23 can be set as a tip, and the tip of the ejector pin 23 can abut against or partially embed into the high-temperature insulation cloth, thereby playing a role in pressing the high-temperature insulation cloth during the cutting process. In the process of the annular blade 22 cutting the high-temperature insulation cloth, the ejector pin 23 can abut against or embed into the center position of the annular high-temperature insulation cloth, preventing the high-temperature insulation cloth from moving in the horizontal direction and causing dislocation, thereby improving the accuracy of cutting.

[0034] Furthermore, on the basis of the above-mentioned embodiment, the tip of the ejector pin 23 points from the direction of the annular blade 22 of the main body 21, and exceeds the blade end of the inner ring blade 221. That is to say, when the ejector pin 23 and the annular blade 22 gradually contact the high-temperature insulation cloth as the main body 21 of the cutter 20 rotates downward, the ejector pin 23 contacts the high-temperature insulation cloth before the inner ring blade 221 of the annular blade 22, that is, the ejector pin 23 presses the center of the high-temperature insulation cloth first. Such an arrangement further ensures the stability of the subsequent process of the annular blade 22 cutting the high-temperature insulation cloth, further avoids the horizontal movement of the high-temperature insulation cloth and causes dislocation, thereby improving the cutting accuracy.

[0035] Further, based on the above embodiment, the distance difference between the tip of the ejector pin 23 and the edge of the inner ring blade 221 can be any value between 0.1 mm and 0.5 mm. Exemplarily, the distance difference between the tip of the ejector pin 23 and the edge of the inner ring blade 221 is set to 0.3 mm.

[0036] In some embodiments of the present invention, the cutter 20 further includes a cylindrical elastic pressure ring, the first end of which is fixed to the bottom of the cutter body 21, and the elastic pressure ring is coaxially arranged with the inner ring blade 221 and the outer ring blade 222. When the elastic pressure ring is in a naturally stretched state without compression, the end of the second end of the elastic pressure ring is 3-5 mm higher than the blade end of the inner ring blade 221. When cutting, the elastic pressure ring elastically contracts and presses against the high-temperature insulation cloth, which is conducive to ensuring the flatness of the high-temperature insulation cloth. After the cutting is completed, the elastic pressure ring stretches under the action of elastic recovery, and the cut annular high-temperature insulation cloth is automatically ejected from between the inner ring blade 221 and the outer ring blade 222. In one example, the elastic pressure ring can be a columnar spring. In another example, the elastic pressure ring can be an elastic rubber ring.

[0037] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
