Description

Technical Field

[0001] This utility model relates to the field of edge grinding wheel manufacturing and processing, and in particular to a water-based edge grinding wheel. Background Technology

[0002] A wet-grinding edge wheel is an abrasive tool that uses diamond as its main abrasive; it is also known as a diamond edge grinding wheel. It possesses extremely high hardness and wear resistance. Wet-grinding edge wheels are widely used in the precision machining and surface treatment of various materials, such as grinding ceramic products like tiles and porcelain, or polishing and grinding stone materials like marble and granite.

[0003] Existing water-based grinding wheels consist of a grinding wheel base and diamond cutting heads that are either directly and integrally formed on the grinding wheel base or formed first and then welded onto the grinding wheel base. However, water-based grinding wheels generate a large amount of heat during operation, and most require a water cooling system for cooling during grinding. Even so, the diamond cutting heads of existing water-based grinding wheels experience significant wear, and the service life of the grinding wheels cannot meet the industry's continuous processing needs.

[0004] Furthermore, existing diamond cutting tips are typically manufactured using axial compression forming, such as... Figure 1 As shown in direction a, the above-mentioned axial compression forming method for diamond cutting heads will result in a certain height difference in the axial (longitudinal) horizontal height of diamond cutting heads from different batches. It is necessary to use a grinding wheel to repeatedly and multiple times in the subsequent grinding or sharpening process until the uniform dimensional requirements are met. This process is complicated, the consumption of consumables such as grinding wheels is large, and the processing cost is high.

[0005] Therefore, it is necessary to improve the structure of existing grinding wheels in order to obtain a grinding wheel with a long service life and low production cost. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a water-grinding edge grinding wheel.

[0007] The objective of this utility model is achieved through the following technical solution: a water-cooled grinding wheel, comprising a grinding wheel base and diamond cutting heads, wherein a plurality of diamond cutting heads are arranged in a ring at intervals on the edge of the grinding wheel base, the interval between two adjacent diamond cutting heads being 1-1.5mm; the outer and inner ring sidewalls of each diamond cutting head along its length are concentric arc surfaces, and a plurality of water drainage grooves for heat dissipation are recessed along the vertical direction on the outer ring sidewall of each diamond cutting head, the water drainage grooves being equally spaced on the entire outer ring sidewall of the diamond cutting head, the width of the water drainage grooves being 1.5-2.5mm, the depth being 0.5-1.5mm, and the height being 10-25mm.

[0008] Optionally, the cross-sectional width of each diamond tip is 18-25 mm.

[0009] Optionally, the cross-sectional length of each diamond tip is 30-45 mm.

[0010] Optionally, the height of each diamond cutting tip is 10-25 mm.

[0011] Optionally, the number of diamond cutting tips is 16-20.

[0012] Optionally, each diamond cutting tip includes an outer ring layer and an inner ring layer, the outer ring layer being a fine-grinding layer and the inner ring layer being a wear-resistant layer, and the outer ring layer and the inner ring layer being respectively coated with a metal powder; the outer ring layer and the inner ring layer are integrally formed and formed by radial pressure.

[0013] Optionally, each diamond cutting tip has an outer ring with a cross-sectional width of 5-10 mm and an inner ring with a cross-sectional width of 5-15 mm, and the outer and inner rings have the same height.

[0014] Optionally, the bottom of the diamond cutter head is welded to the edge of the grinding wheel base.

[0015] Optionally, the grinding wheel base is annular, and the outer ring diameter of the base is 200-300mm.

[0016] Optionally, the grinding wheel base surface is provided with an assembly hole at the center.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) This application sets multiple equally spaced drainage grooves on the outer ring sidewall of the diamond cutter head, combined with the spacing between two adjacent diamond cutter heads. The position design of the drainage grooves and the spacing allows the cooling water to be quickly introduced directly into the outer circumference and inner diameter of the grinding surface during operation, thereby effectively reducing the temperature of the diamond cutter head, improving the wear resistance of the diamond cutter head and the service life of the grinding wheel, and meeting the grinding needs of long-term continuous processing. Compared with conventional grinding wheels without drainage groove structure, its grinding time will increase by more than 40%.

[0019] (2) The main body of this edge grinding wheel has two layers of abrasive: the outer layer is a fine grinding layer, and the inner layer is a wear-resistant layer. On the one hand, this reduces ceramic edge chipping and improves the yield of ceramic products. On the other hand, the double-layer structure allows for one-time molding and changes the pressure direction of the grinding block, ensuring the uniformity of the product's horizontal height. It also eliminates the need for grinding / sharpening processes, greatly reducing costs. The service life of the edge grinding wheel is increased by more than 2.5 times. Attached Figure Description

[0032] like Figure 1-5As shown, a water-cooled grinding wheel includes a grinding wheel base 1 and diamond cutting heads 2. Several diamond cutting heads 2 are arranged in a ring at intervals on the edge of the grinding wheel base 1, and the interval c between two adjacent diamond cutting heads 2 is in the range of 1-1.5mm. The outer and inner ring sidewalls of each diamond cutting head 2 are concentric arc surfaces in the length direction. Several drainage grooves 21 for heat dissipation are recessed along the vertical direction on the outer ring sidewall of each diamond cutting head 2.

The width d1 of each drainage groove 21 is 1.5-2.5mm, the depth d2 is 0.5-1.5mm, and the height d3 is 10-25mm.

[0033] This application, by setting multiple equally spaced drainage grooves 21 on the outer ring sidewall of the diamond cutter head 2, combined with the spacing between two adjacent diamond cutter heads 2, the position design of the drainage grooves 21 and the spacing allows cooling water to be quickly introduced directly into the outer circumference and inner diameter of the grinding surface during operation, thereby effectively reducing the temperature of the diamond cutter head 2, effectively improving the wear resistance of the diamond cutter head 2 and the service life of the grinding wheel, and meeting the grinding needs of long-term continuous processing. Compared with conventional grinding wheels without drainage grooves 21, its grinding time increases by more than 40%.

The outer ring layer 22 and the inner ring layer 23 are integrally formed and shaped by radial pressure. Figure 1 The direction shown is b.

[0039] This edge-grinding wheel has two layers of abrasive: an outer fine-grinding layer and an inner wear-resistant layer. This design reduces ceramic edge chipping, increasing the yield of ceramic products. Furthermore, the double-layer structure allows for one-time forming and alters the pressure direction of the grinding block, ensuring uniform product level and eliminating the need for grinding / sharpening processes, thus significantly reducing costs. The service life of the edge-grinding wheel is increased by more than 2.5 times.

[0040] As a further preferred option, the cross-sectional width s11 of the outer ring 22 of each diamond tool tip 2 is 5-10mm, the cross-sectional width s12 of the inner ring 23 is 5-15mm, and the height of the grinding wheels of the outer ring 22 and the inner ring 23 is the same.
