Description

Technical Field

[0001] This utility model belongs to the field of diamond saw blade technology, and in particular relates to a long-life diamond saw blade. Background Technology

[0002] Saw blades are a general term for thin, circular cutting tools used to cut solid materials. Saw blades can be categorized as follows: diamond saw blades for stone cutting; high-speed steel saw blades (without carbide blade holders) for metal cutting; and carbide saw blades for cutting solid wood, furniture, engineered wood, aluminum alloys, aluminum profiles, radiators, plastics, and PVC. Diamond saw blades are widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics.

[0003] Existing diamond saw blades tend to generate ribbon-like chips during sawing, and these chips can curl and deform in the inter-tooth grooves, making chip removal difficult. In addition, during sawing, the left and right sides of the cutter head rub against the cut surface of the workpiece, sometimes even causing the saw to jam, which seriously affects the service life of the cutter head. Utility Model Content

[0004] The purpose of this invention is to provide a long-life diamond saw blade to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A long-life diamond saw blade includes a saw blade base. Multiple chip grooves arranged in a circumferential array are provided along the edge of the saw blade base. Each chip groove has an L-shaped opening on one side. The L-shaped opening is composed of a bottom surface and a rear end surface. A detachably connected cutting head is installed in each L-shaped opening. A chip-rolling groove is provided in the middle part of the end of the cutting head away from the rear end surface. A chip-separating groove is provided on the upper surface of the cutting head in the middle part of the chip-rolling groove. The front and rear side walls of the cutting head are provided with protruding edges at the end of the chip-rolling groove.

[0006] Preferably, the upper surface of the bottom surface is provided with a semi-circular positioning groove, the surface of the semi-circular positioning groove is provided with a fixing hole, the bottom of the cutter head is provided with a positioning boss whose size matches the semi-circular positioning groove, the surface of the cutter head is provided with a threaded hole that penetrates the positioning boss, and the upper surface of the cutter head is provided with a countersunk hole concentric with the threaded hole, and the threaded hole and the fixing hole are internally threaded with a screw.

[0007] Preferably, a limiting groove is provided at the bottom of the rear end face, and a limiting block is provided at the bottom of the end of the cutter head away from the chip groove, which is distributed corresponding to the limiting groove. The size of the limiting block matches the size of the limiting groove.

[0008] Preferably, the chip groove has a V-shaped structure and is provided with an arc.

[0009] Preferably, the chip-splitting groove is configured as a semi-circular structure, and the axis of the chip-splitting groove is perpendicular to the axis of the chip-rolling groove.

[0010] Preferably, the convex edge is configured as a bevel.

[0011] The long-life diamond saw blade of this invention has the following advantages:

[0012] 1. This utility model, through the cooperation between the limiting block and the limiting groove, allows the limiting block to engage with the limiting groove on the rear end face during the installation of the cutter head. Combined with the positioning boss and the semi-circular positioning groove, it limits the cutter head in six directions: front-back, left-right, and up-down, achieving positioning and clamping of the cutter head. This ensures the stability of the cutter head during operation, thereby improving its service life. Furthermore, the threaded hole and screw securely connect the cutter head to the saw blade base, facilitating disassembly and installation, and making cutter head replacement convenient. This significantly saves costs and reduces resource waste.

[0013] 2. By setting the convex edge, this utility model can not only ensure that the surface roughness of the saw cut surface meets certain precision requirements, reduce friction between the cutter head and the workpiece, and reduce cutting heat, but also avoid saw jamming, making the sawing process smoother, thereby extending the service life of the cutter head.

[0014] 3. The combination of chip breaking groove and chip curling groove can reduce the width of the cutting edge, making the workpiece easier to deform during sawing, thereby reducing the cutting force and facilitating the chips to be contained in the tooth groove or discharged from the groove, thus enhancing the chip breaking effect.

[0028] To better understand the purpose, structure, and function of this utility model, the following detailed description of a long-life diamond saw blade, in conjunction with the accompanying drawings, is provided.

[0029] like Figure 1-6 As shown, this utility model discloses a long-life diamond saw blade, comprising a saw blade base 1. Multiple chip grooves 2 arranged in a circular array are provided along the edge of the saw blade base 1. Each chip groove 2 has an L-shaped opening on one side, the L-shaped opening being formed by a bottom surface 4 and a rear end surface 5. A detachably connected cutting head 3 is installed in each L-shaped opening. A semi-circular positioning groove 6 is provided on the upper surface of the bottom surface 4, and a fixing hole 7 is provided on the surface of the semi-circular positioning groove 6. A positioning boss 11 with dimensions matching the semi-circular positioning groove 6 is provided at the bottom of the cutting head 3. The surface of the blade 3 is provided with a threaded hole 12 that penetrates the positioning boss 11, and the upper surface of the blade head 3 is provided with a countersunk hole 13 concentric with the threaded hole 12. The threaded hole 12 is connected to the fixing hole 7 with a screw. Through the cooperation between the positioning boss 11 and the semi-circular positioning groove 6, the blade head 3 is positioned and clamped. Under the action of the threaded hole 12 and the screw, the blade head 3 is fixedly connected to the saw blade base 1, which facilitates the disassembly and installation of the blade head 3 and the replacement of the blade head 3, greatly saving costs and reducing the waste of resources. A limiting groove 8 is provided at the bottom of the rear end face 5. A limiting block 15 corresponding to the limiting groove 8 is provided at the bottom of the end of the cutter head 3 away from the chip groove 10. The size of the limiting block 15 matches the size of the limiting groove 8. Through the cooperation between the limiting block 15 and the limiting groove 8, when the cutter head 3 is installed, the limiting block 15 of the cutter head 3 is inserted into the limiting groove 8 of the rear end face 5. Together with the positioning boss 11 and the semi-circular positioning groove 6, the cutter head 3 is limited in six directions: front-back, left-right, up-down, and left-right. This ensures the stability of the cutter head 3 during operation and improves the service life of the cutter head 3.

[0030] A chip-collecting groove 10 is provided in the middle part of the end of the cutter head 3 away from the rear end face 5. The chip-collecting groove 10 has a V-shaped structure and is curved. A chip-breaking groove 9 is provided in the middle part of the chip-collecting groove 10 on the upper surface of the cutter head 3. The chip-breaking groove 9 has a semi-circular structure and its axis is perpendicular to the axis of the chip-collecting groove 10. Through the cooperation between the chip-breaking groove 9 and the chip-collecting groove 10, the cutting edge width can be reduced, and the workpiece can be easily deformed during sawing, thereby reducing the cutting force and facilitating the chips to be contained in the tooth groove or discharged from the groove, thus enhancing the chip breaking effect. The front and rear side walls of the cutter head 3 are provided with protruding edges 14 at one end of the chip groove 10. The protruding edges 14 are set as inclined surfaces. By setting the protruding edges 14, a side clearance is generated between the cutter head 3 and the cutting surface of the workpiece. This not only ensures that the surface roughness of the sawing surface meets certain precision requirements and reduces friction between the cutter head 3 and the workpiece, thus reducing cutting heat, but also avoids saw jamming, making the sawing process smoother and extending the service life of the cutter head 3.
