Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing and processing fused-cast refractory materials, in particular to a diamond grinding wheel and a processing platform. Background Art

[0002] Photovoltaic glass furnaces are a crucial step in the production of photovoltaic glass. Due to its unique chemical composition and optical requirements, photovoltaic glass is typically formed using a calendaring process. During this process, the calendaring machine must be connected to the glass furnace's lip bricks. These lip bricks are consumables and require frequent replacement throughout the glass furnace's lifecycle.

[0003] Lip bricks on the market are primarily made of three materials: sillimanite, fused alumina, and zirconium mullite. Each material has its own advantages and disadvantages, and their service life generally ranges from 3 to 5 months. The main problem with fused alumina lip bricks is that they are prone to transverse fractures or cracks during preheating before the lead-in, which affects the product's performance. The advantages of fused alumina lip bricks include a long service life and erosion resistance, with a lifespan of approximately 5 months or more in actual use. However, due to their unique shape, lip bricks are extremely difficult to process and currently can only be polished manually. Utility Model Content

[0008] The grinding wheel is in a frustum shape, and a plurality of grinding wheel teeth extend from a proximal end of the grinding wheel body to a distal end of the grinding wheel body, and outer sides of the grinding wheel teeth include a diamond coating;

[0009] The portions of the plurality of grinding wheel teeth adjacent to the proximal end of the grinding wheel body include circumferentially distributed concave grinding portions, and the outer diameters of the grinding wheel teeth gradually increase from the concave grinding portions toward the distal end of the grinding wheel body, thereby forming outer arc grinding portions that match the concave grinding portions;

[0015] As a further solution of the present invention: at least part of the second processing teeth includes two or more sub-processing teeth, and multiple planes determined by the extension direction of each of the sub-processing teeth basically intersect with the central axis of the grinding wheel.

[0016] As a further solution of the present invention: the second processing teeth also include tooth gaps between the sub-processing teeth, the tooth gaps are smaller than the spacing between the second processing teeth, the spacing between the second processing teeth is 35mm-40mm, and the width of the tooth gaps is 0.5mm-0.8mm.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 2 and Figure 3 As shown, a diamond grinding wheel comprises:

[0029] The grinding wheel 2 includes a grinding wheel body 21 and a plurality of grinding wheel teeth 22 uniformly distributed circumferentially on the grinding wheel body 21. The grinding wheel body 21 usually has a central axis. The outer side surfaces of the plurality of grinding wheel teeth 22 cooperate with each other, that is, when the grinding wheel body 21 rotates circumferentially along its central axis, the circumferential outer grinding surfaces formed by the grinding wheel teeth 22 can basically coincide (for example, the grinding wheel 2 is usually in the shape of a truncated cone). The plurality of grinding wheel teeth 22 extend from the proximal end of the grinding wheel body 21 to the distal end of the grinding wheel body 21. The width of the teeth of the plurality of grinding wheel teeth 22 corresponding to the outer arc grinding portion is greater than the width of the teeth corresponding to the recessed grinding portion (for example, the width of the plurality of grinding wheel teeth 22 can gradually increase from the proximal end to the distal end of the grinding wheel body 21). The width of the grinding wheel tooth 22 usually refers to the size of the line segment corresponding to the outer side surface of the tooth on the cross section perpendicular to the axis of the grinding wheel body 21. When comparing the width of the teeth in the outer arc grinding portion and the recessed grinding portion, the entire outer arc grinding portion can usually be used. The outer side of the grinding wheel teeth includes a diamond coating, and the portion of the plurality of grinding wheel teeth 22 adjacent to the proximal end of the grinding wheel body 21 includes circumferentially distributed concave grinding portions. The concave grinding portion refers to the outer diameter of the proximal and distal sides of the circumferential grinding surface formed by the grinding portion when the grinding wheel teeth 22 rotate circumferentially, which is significantly larger than the outer diameter of the portion between the proximal and distal sides thereof. The proximal and distal sides of the concave grinding portion are The outer diameters can be basically equal. From the recessed grinding portion to the distal end of the grinding wheel body 21, the outer diameter of the grinding wheel teeth 22 gradually increases, thereby forming an outer arc grinding portion that matches the recessed grinding portion. The outer arc grinding portion refers to the outer diameter of the proximal side of the circumferential grinding surface formed by the grinding portion when the grinding wheel teeth rotate circumferentially is significantly smaller than the outer diameter of other parts. The grinding surface corresponding to the outer side of the grinding portion is arc-shaped, and the center direction of the arc is toward the axis of the grinding wheel body 21.

[0030] The diamond grinding wheel can be used to process lip bricks for rolled glass furnaces. In its actual application process, since the proximal end of the grinding wheel body 21 is circumferentially distributed with a concave grinding portion, a convex outer arc grinding portion is formed from the concave grinding portion to the distal end of the grinding wheel body 21 to match the concave grinding portion. Through the concave concave grinding portion and the convex outer arc grinding portion, the brick blank can be processed into the following at one time: Figure 1 The style of the lip brick 1 shown can complete the processing of the arc-shaped protrusion and the concave arc surface of the lip brick at one time, and can also complete the grinding and polishing of the lip brick 1, which is beneficial to improving the processing efficiency of the lip brick while ensuring the processing accuracy.

[0031] In some embodiments of the present invention, the extension direction of each grinding wheel tooth 22 matches the axial direction of the grinding wheel body 21, that is, the multiple planes determined by the extension direction of each grinding wheel tooth basically intersect with the central axis of the grinding wheel.

[0032] like Figure 1 As shown, the grinding wheel body 21 can be truncated cone-shaped. For ease of description, a plane perpendicular to the central axis of the grinding wheel body 21 is defined as a cross section. The side of the grinding wheel body 21 with a smaller cross-sectional area is defined as the proximal end, which generally corresponds to the proximal end of the grinding wheel teeth 22. The side of the grinding wheel body 21 with a larger cross-sectional area is defined as the distal end. The axial direction of the grinding wheel body 21 is the direction extending from the proximal end of the grinding wheel body 21 to the distal end of the grinding wheel body 21, which is horizontally arranged along the central axis of the grinding wheel body 21. In the axial direction of the grinding wheel body 21, the outer arc grinding portion generally has a longer length than the concave grinding portion to accommodate the lip brick to be processed. For example, in the axial direction of the grinding wheel body 21, the length of the outer arc grinding portion can be 100 mm to 280 mm, and the length of the concave grinding portion can be 22 mm to 50 mm.

[0033] like Figure 2 and 3 As shown, the grinding wheel teeth 22 include a first processing tooth 221 and a second processing tooth 222, which are connected in sequence from the proximal end to the distal end of the grinding wheel body 21. The width of the second processing tooth 222 is greater than the width of the first processing tooth 221. The width of the first processing tooth 221 and the second processing tooth 222 generally refers to the size of the line segment corresponding to the outer surface of the tooth on a cross section perpendicular to the central axis of the grinding wheel body 21. When comparing the widths of the first processing tooth 221 and the second processing tooth 222, the average width of the entire first processing tooth 221 and the entire second processing tooth 222 is generally used for comparison. For example, the width of the first processing tooth 221 can be 5 to 15 mm, and the width of the second processing tooth 222 can be 12 to 28 mm.

[0034] By designing the grinding wheel teeth 22 into the above-mentioned form, since multiple grinding wheel teeth 22 extend from the proximal end of the grinding wheel body 21 to the distal end of the grinding wheel body 21 and their width increases, the increase in the width of the second processing teeth 222 can ensure that the proportion of the processing surface to the entire circumferential grinding portion is ensured, which is beneficial to ensuring the processing efficiency and grinding effect of the lip brick.

[0035] In some embodiments of the present invention, at least some of the second processing teeth may include two or more sub-processing teeth, the extension direction of which matches the axial direction of the grinding wheel body 21. That is, the multiple planes defined by the extension directions of the sub-processing teeth substantially intersect the central axis of the grinding wheel 2. The design of multiple sub-processing teeth can reduce the temperature of the grinding part during machining, thereby reducing the thermal impact of the machining process.

[0036] The second processing teeth also include tooth gaps between the sub-processing teeth. The existence of the tooth gaps facilitates the adjustment of the width of the sub-processing teeth, which can ensure the proportion of the processing surface to the entire circumferential grinding portion, and is beneficial to ensuring the processing efficiency and grinding effect of the lip brick. The tooth gap is usually smaller than the spacing between the second processing teeth. For example, the spacing between the second processing teeth is 35mm-40mm, and the width of the tooth gap can be 0.5mm-0.8mm. The spacing of the second processing teeth 222 and the width of the tooth gap usually refer to the size of the line segment corresponding to the outer side surface of the tooth on the cross section perpendicular to the axis of the grinding wheel body 21, and the size between the line segments formed by the outer side surface of the tooth and the adjacent end points of adjacent line segments; when describing the spacing of the second processing teeth 222 and the width of the tooth gap, it can be the average spacing between each second processing tooth 222, or the average tooth gap between each sub-processing tooth.

[0037] like Figure 2 and 3 As shown, the plurality of grinding wheel teeth 22 can have an appropriate height to ensure that the grinding wheel teeth 22 themselves maintain a certain mechanical strength. The height of the grinding wheel teeth 22 generally refers to the distance in the radial direction from the outer side of the grinding wheel body 21 to the outer side of the grinding wheel teeth 22. For example, the height of the grinding wheel teeth 22 can be 160 mm to 200 mm. In the same cross-section, the height of each grinding wheel tooth 22 can be substantially the same, that is, the grinding wheel body 21 and the grinding wheel 2 are substantially coaxial as a whole. The outer side of the longitudinal section of the concave grinding portion (i.e., the section where the axis of the grinding wheel body 21 is located) is usually arc-shaped, so that it can cooperate with the outer arc grinding portion to adapt to the shape of the lip brick to be processed. For example, the curvature of the outer side of the longitudinal section of the concave grinding portion can be 180 degrees, and the outer side of the longitudinal section of the outer arc grinding portion (i.e., the section where the axis of the grinding wheel body 21 is located) is an outward convex arc grinding portion close to a quarter circle. The curvature of the outer side of the outer arc grinding portion can be 55 degrees-85 degrees, and the length ratio of the arc length of the concave grinding portion and the arc length of the outer arc grinding portion can be 1:2.8-5.8. The minimum inner diameter of the concave grinding portion can be 12 mm, and the maximum outer diameter of the outer arc grinding portion can be 170 mm. The arc lengths of the concave grinding portion and the outer arc grinding portion usually refer to the size of the line segment corresponding to the outer side of the longitudinal section of the concave grinding portion and the outer arc grinding portion (i.e., the section where the axis of the grinding wheel body 21 is located).

[0038] like Figure 3 As shown, the grinding wheel 2 further includes a proximal extension portion 211, which is connected to the proximal end of the grinding wheel body 21 and is coaxially distributed therewith, and a plurality of grinding wheel teeth 22 extend to the proximal extension portion 211. The proximal extension portion 211 is conducive to improving the overall structural strength of the grinding wheel 2.

[0039] The proximal extension portion 211 generally needs to have a certain length. For example, in the axial direction of the grinding wheel body 21 , the length of the proximal extension portion 211 may be 75 mm to 85 mm, and the outer diameter may be 280 mm to 310 mm.

[0040] The present utility model also provides a processing platform, which includes a platform body and a grinding drive mechanism matched with the platform body, and also includes a diamond grinding wheel and pin holes located at both ends of the grinding wheel body 21 of the diamond grinding wheel. The diamond grinding wheel is fixed to the grinding drive mechanism through the pin holes.

[0041] The diamond grinding wheel and processing platform provided in this application can be used to process lip bricks for rolled glass furnaces. In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0042] During use, the grinding drive mechanism of the processing platform replaces the grinding wheel specially used for processing the upper lip brick, and the brick to be processed is placed on the processing platform. The concave recessed grinding part and the convex outer arc grinding part can complete the processing of the arc-shaped protrusion and the concave arc surface of the lip brick at one time, and the grinding and polishing of the lip brick 1 can be completed at the same time, which is beneficial to improving the processing efficiency of the lip brick. Since the multiple grinding wheel teeth 22 extend from the proximal end of the grinding wheel body 21 to the distal end of the grinding wheel body 21, their width gradually increases. The increase in the width of the second processing tooth 222 can ensure that the processing surface accounts for the proportion of the entire circumferential grinding part, which is beneficial to ensuring the processing efficiency and grinding effect of the lip brick.

[0043] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
