[0031] It should be appreciated that the high temperature insulation cloth uses the temperature range of 100 DEG C to 350 DEG C.

[0032] The utility model discloses an annular high temperature insulation cloth's processing device 100, base 10 is used for installing tool 20, and is used for pressing high temperature insulation cloth, the bottom of base 10 passes through the recess 11 of setting to limit and accommodate the part of high temperature insulation cloth to be cut, utilize the flange 12 of recess 11 to play the role of pressing high temperature insulation cloth, guarantee the subsequent tool 20 can cut smoothly, the main part 21 of tool 20 is screwed in base 10, the main part 21 is rotated with base 10, and the annular cutting edge 22 connected in the bottom is rotated and generates vertical movement simultaneously, to make annular cutting edge 22 can cut high temperature insulation cloth in the process of movement.

[0033] Further, the shape of the base 10 can be set as a column or a cube, and the embodiment does not make specific limitation thereon. Exemplarily, please continue to refer to Figure 1 and Figure 2 , and refer to Figure 3 and Figure 4 , the base 10 is set as a cylinder, the bottom of the base 10 is provided with a recess 11, the recess 11 can be formed in the bottom of the base 10 by an integral molding manner, and the cross-sectional shape of the recess 11 can be set as a circle, an ellipse or a rectangle according to actual conditions. In the embodiment, the recess 11 is set as a circular recess 11, and correspondingly, the flange 12 formed by the edge of the recess 11 is set as a circular flange 12. Such a setting manner enables the flange 12 to uniformly 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 in the cutting process, and ensuring the smooth forming of the annular high temperature insulation cloth.

[0034] On the basis of the above-mentioned embodiment, the bottom of the flange 12 is provided with a chamfer 121, as shown in Figure 3 and Figure 4 , the chamfer 121 can be arranged on the inner side of the flange 12. Understandably, the bottom of the flange 12 is in contact with the high temperature insulation cloth for pressing the high temperature insulation cloth. In the embodiment, the arrangement of the chamfer 121 can reduce the contact area between the flange 12 and the high temperature insulation cloth. Under the condition that the overall weight of the processing device is unchanged, reducing the contact area between the flange 12 and the high temperature insulation cloth can increase the pressure, thereby further improving the stability of the high temperature insulation cloth, reducing the possibility of warping of the high temperature insulation cloth in the cutting process, and ensuring the smooth forming of the annular high temperature insulation cloth.

[0035] Further, the shape of the main part 21 of the tool 20 can also be set as a column. In a possible embodiment, as shown inFigure 2 , Figure 5 and Figure 6 As shown, the main body 21 is shaped as a stepped shaft. 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.

[0036] For example, such as Figure 2 and Figure 6 As shown, the base 10 has a threaded hole along the axial direction, which communicates with the groove 11 at the bottom of the base 10. The diameter of the threaded rod 211 of the main body 21 of the cutter 20 is larger than the diameter of the smooth rod 212. When the cutter 20 is installed on the base 10, the threaded hole of the base 10 cooperates with the threaded rod 211 of the main body 21 of the cutter 20. The smooth rod 212 of the main body 21 of the cutter 20 is located above the base 10. The annular blade 22 at the bottom of the main body 21 of the cutter 20 can partially or completely extend into the groove 11 of the base 10 and can move relative to the high-temperature insulation cloth. That is, the cutter 20 can rotate relative to the base 10. While rotating, it can achieve vertical movement, thereby causing the annular blade 22 at the bottom of the main body 21 to cut the high-temperature insulation cloth pressed by the base 10 in a rotating downward manner.

[0037] Based on the above implementation methods, such as Figure 1 As shown, the processing device also includes a wrench 30, which is connected to the cutting tool 20, thereby enabling the cutting tool 20 to rotate relative to the base 10. The wrench 30 can be used for manual operation, or it can be connected to external automated machinery to achieve automatic cutting by the cutting tool 20. This embodiment does not specifically limit this. Figure 1 As shown, the wrench 30 is connected to the smooth rod 212 of the main body 21 of the cutter 20. The wrench 30 and the smooth rod 212 can be connected by thread, snap-fit, welding or integral molding. This embodiment does not make specific limitations on this.

[0038] For example, the guide rod 212 has a threaded hole extending through it along the vertical axis. The wrench 30 includes two rod-shaped wrenches 30 arranged opposite each other. The outer wall of each rod-shaped wrench 30 is provided with an external thread that mates with the threaded hole. Thus, the two rod-shaped wrenches 30 are threadedly connected to opposite sides of the guide rod 212. The operator can rotate the tool 20 by simultaneously holding the two rod-shaped wrenches 30. The distance between the two rod-shaped wrenches 30 can be adjusted, making it easy for the operator to adjust according to the actual situation. In this embodiment, the rod-shaped wrenches 30 are easy to operate, further improving the processing efficiency of the processing device.

[0039] Furthermore, such as Figure 2 , Figure 5 and Figure 6As shown, the cutter 20 comprises an annular cutting edge 22 for cutting high-temperature thermal insulation cloth, which can be arranged at the bottom of the cutter 20 body 21 by welding or integral molding, and in some embodiments of the utility model, the annular cutting edge 22 comprises an inner circle cutting edge 221 and an outer circle cutting edge 222, the inner circle cutting edge 221 is used for cutting the inner circle of the annular high-temperature thermal insulation cloth, and the outer circle cutting edge 222 is used for cutting the outer circle of the annular high-temperature thermal insulation cloth.

[0040] On the basis of the above-mentioned embodiments, the projection of the annular cutting edge 22 can be a closed annular or an unclosed annular in the plane perpendicular to the axis of the body 21, that is, the inner circle cutting edge 221 can be arranged as a closed circular cutting edge or as a circular cutting edge ring formed by a plurality of arc-shaped cutting edges arranged at intervals, and the outer circle cutting edge 222 can be arranged as a closed circular cutting edge or as a circular cutting edge ring formed by a plurality of arc-shaped cutting edges arranged at intervals.

[0041] Exemplarily, please continue to refer to Figure 2 、 Figure 5 and Figure 6 , in the plane perpendicular to the axis of the body 21, the cross sections of the inner circle cutting edge 221 and the outer circle cutting edge 222 are both arranged as closed circles, the outer circle cutting edge 222 is connected at the outer edge of the bottom surface of the body 21, the outer side of the cutting end of the outer circle cutting edge 222 is inclined inward, and the inner side is perpendicular to the high-temperature thermal insulation cloth; the inner circle cutting edge 221 is located inside the outer circle cutting edge 222, the inner side of the cutting end of the inner circle cutting edge 221 is inclined outward, and the outer side is perpendicular to the high-temperature thermal insulation cloth.

[0042] Further, in some embodiments of the utility model, as shown in Figure 6 , from the direction in which the body 21 points to the annular cutting edge 22, the cutting end of the inner circle cutting edge 221 exceeds the cutting end of the outer circle cutting edge 222, that is, in the process in which the annular cutting edge 22 gradually contacts the high-temperature thermal insulation cloth downward with the rotation of the cutter 20 body 21, the inner circle cutting edge 221 contacts the high-temperature thermal insulation cloth earlier than the outer circle cutting edge 222, that is, the inner circle cutting edge 221 starts cutting the high-temperature thermal insulation cloth first, and the inner circle of the annular high-temperature thermal insulation cloth is formed earlier than the outer circle, and such an arrangement can prevent the problem caused by the formation of the outer circle first, that is, prevent the high-temperature thermal insulation cloth from rotating together with the outer circle cutting edge 222 after the completion of cutting by the outer circle cutting edge 222, so that the inner circle cutting edge 221 cannot complete the cutting, thereby ensuring the processing efficiency and precision of the annular high-temperature thermal insulation cloth.

[0043] Further, on the basis of the above-mentioned embodiments, the distance difference between the cutting end of the inner circle cutting edge 221 and the cutting end of the outer circle cutting edge 222 can be any value between 0.1mm-0.5mm, exemplarily, the distance difference between the cutting end of the inner circle cutting edge 221 and the cutting end of the outer circle cutting edge 222 is set to 0.3mm.

During the process of cutting the high-temperature heat-insulating cloth by the annular cutting edge 22, the thimble 23 can abut or embed in the center position of the annular high-temperature heat-insulating cloth, preventing the high-temperature heat-insulating cloth from being disordered in the horizontal direction to cause misplacement, and improving the cutting accuracy.

[0045] Further, on the basis of the above-mentioned embodiments, the pointed end of the thimble 23 exceeds the edge end of the inner circle cutting edge 221 from the direction of the main body 21 pointing to the annular cutting edge 22, that is, during the process of the thimble 23 and the annular cutting edge 22 gradually contacting the high-temperature heat-insulating cloth downward along the rotation of the cutter 20 main body 21, the thimble 23 contacts the high-temperature heat-insulating cloth earlier than the inner circle cutting edge 221 of the annular cutting edge 22, that is, the thimble 23 compresses the center of the high-temperature heat-insulating cloth first, and such a setting mode further guarantees the stability of the process of cutting the high-temperature heat-insulating cloth by the annular cutting edge 22, further avoids the high-temperature heat-insulating cloth from being disordered in the horizontal direction to cause misplacement, thereby improving the cutting accuracy.

[0046] Further, on the basis of the above-mentioned embodiments, the distance difference between the pointed end of the thimble 23 and the edge end of the inner circle cutting edge 221 can be any value between 0.1mm-0.5mm, and exemplarily, the distance difference between the pointed end of the thimble 23 and the edge end of the inner circle cutting edge 221 is set to 0.3mm.
