Description

Technical Field

[0001] This utility model belongs to the field of diamond saw blade technology, and in particular relates to a diamond blade that can be obliquely cut. Background Technology

[0002] Diamond saw blades, as a core tool in the field of hard material cutting, are mainly used for planar cutting of materials with high hardness and wear resistance, such as marble, granite, and cement concrete. They play a crucial role in fields such as architectural decoration, stone processing, and municipal engineering. Their function is not limited to cutting and separating materials; more importantly, they shape the edges and contours of materials and achieve surface smoothness through precise grinding. The performance advantage of diamond saw blades stems from their unique structural design—typically using diamond cutting heads, a composite structure formed by high-temperature and high-pressure sintering of diamond particles and metal binders. Currently, the overall structural arrangement of diamond saw blades is relatively simple, often employing traditional uniform tooth shapes or continuous edge designs. This results in insufficient overall strength of the saw blade, making it prone to breakage and causing chipping when cutting at bevels. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a diamond slice that can be obliquely cut.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A diamond slice that can be obliquely cut includes a matrix and a slice body; the slice body is made of a mixture of diamond and metal powder, and the slice body is disposed on the outer circumference of the matrix;

[0006] The outer edge of the slice body is uniformly provided with multiple sets of sawing teeth in a circular array.

[0007] Each set of sawing teeth includes three tooth blocks. The surface of each tooth block is frosted. A first groove is provided between adjacent tooth blocks. The first groove is U-shaped and its opening faces the outer circumference of the slice body.

[0008] A second groove is provided between two adjacent sets of sawing teeth, and the second groove is in the shape of a broken line.

[0009] Through the above technical solution, when the diamond slice cuts an object, the slice body is made of a mixture of diamond and metal powder, which has high hardness and a wide range of applications. During the cutting process, when the slice body rotates into the object, the generated debris will enter the first and second grooves for buffering. As the slice body rotates out of the object, the first and second grooves can discharge the debris during the cutting process, preventing the debris from hindering the rotation of the slice, thereby improving the cutting speed. In addition, each sawing tooth group has three tooth blocks with gaps between the tooth blocks and between adjacent sawing tooth groups. This arrangement can reduce the resistance of the slice body when cutting the object, making the slice sharper and enhancing its toughness. Furthermore, the abrasive tooth blocks can be polished during cutting, allowing for 45° inclined cutting of 25mm objects without chipping the edges.

[0010] Furthermore, the sawing tooth assembly has a third groove at one end facing the inner circumference of the slice body. The third groove is U-shaped and its opening faces the inner circumference of the slice body.

[0011] The two third grooves are arranged intersecting with the two first grooves.

[0012] Furthermore, the toothed block, the first groove, and the third groove are all inclined, and the inclination direction is consistent with the rotation direction of the slice body during use.

[0013] Furthermore, the depth of the first, second, and third grooves exceeds one-third of the slice body.

[0014] Through the above technical solution, the first groove, the second groove and the third groove can buffer the debris on the inner and outer sides of the cutting surface during the cutting of the slice body, and discharge it as the slice body rotates, thereby improving the debris discharge efficiency, further reducing cutting resistance and improving cutting efficiency.

[0015] Furthermore, the outer ends of the toothed block are rounded, which facilitates cutting the object.

[0016] Furthermore, the substrate is a steel substrate and has a circular structure.

[0017] Furthermore, the base has a mounting hole at its center, and the mounting hole is circular.

[0018] Furthermore, the outer side of the substrate is provided with uniformly distributed protrusions, and the outer side of the protrusions is arc-shaped.

[0019] Furthermore, the height of the bump is 2 / 3 of the base height.

[0020] The above technical solutions improve the strength of the substrate and the bonding strength with the slice body.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model uses the first, second, and third grooves to buffer the debris generated on the cutting surface during the cutting process, and discharge the debris as the slice body rotates, thereby improving the debris discharge efficiency, increasing the cutting speed, and preventing debris from hindering the rotation of the slice, thus improving the cutting speed. Each sawing tooth group has three tooth blocks with gaps between the tooth blocks and between adjacent sawing tooth groups. This arrangement can reduce the resistance of the slice body to the object during cutting, making the slice sharper and more resilient. The frosted tooth blocks can be polished during cutting, allowing for 45° inclined cutting of 25mm objects without chipping the edges.

[0023] 2. The slicing body of this utility model is made of diamond and metal powder mixture. It has high hardness and can cut various hard materials. It has a wide range of applications. Moreover, the arrangement of the sawing teeth can ensure that the cut surface is flat and does not chip. Attached Figure Description

The slice body 2 is disposed on the outer circumference of the substrate 1 and is made of a mixture of diamond and metal powder, bonded to the substrate 1 by cold pressing. Multiple sets of sawing teeth are evenly arranged in a circular array on the outer edge of the slice body 2. The sawing teeth are formed by assembling the substrate 1 and the slice body 2 into a specially patterned steel sintering mold and sintering them. Each set of sawing teeth includes three tooth blocks 3, the surface of which is frosted, and the outer ends of the tooth blocks 3 are rounded to facilitate...

That is, the inclination angle of the tooth block 3, the first groove 31 and the third groove 32 from the outside to the inside is counterclockwise. The depth of the grooves of the first groove 31, the second groove 4 and the third groove 32 exceeds 1 / 3 of the slice body 2.
