Diamond saw blade easy for chip removal and cooling

Abstract

The diamond saw blade comprises a saw blade base body, diamond tool bits are arranged on the surfaces of the two sides of the saw blade base body, and the diamond tool bits on the surfaces of the two sides of the saw blade base body are each divided into a first tool bit and a second tool bit in the circumferential direction at intervals. A first chip removal cooling groove and a second chip removal cooling groove are formed between the adjacent first tool bit and the second tool bit, and a third chip removal cooling groove is further formed in the position, close to the side edge of the saw blade base body, of the first tool bit in an outward penetrating mode. In the saw cutting process, saw dust generated by making contact with a workpiece can enter the first chip removal cooling groove and the second chip removal cooling groove, and is discharged to the outer side of the saw blade from outer ports of the first chip removal cooling groove and the second chip removal cooling groove under the action of centrifugal force, and therefore the problem that the diamond saw blade is clamped in the rotating process due to the saw dust is solved; and meanwhile, under the high-speed rotation effect of the diamond saw blade, the cooling effect is achieved through the first chip removal cooling groove and the second chip removal cooling groove, and the problem that workpieces deform at high temperature after being heated and accumulated is solved.

Description

Technical Field

[0001] This application relates to the field of diamond saw blade technology, and more particularly to a diamond saw blade that is easy to remove chips and cool down. Background Technology

[0002] Diamond saw blades typically consist of a saw blade body and a diamond working layer covering (bonded) its surface. The saw blade body is usually made of a metal material, such as steel, and serves to support, mount, and fix the diamond particles. It has a certain strength and toughness to ensure the stability of the saw blade during high-speed rotation and cutting. The diamond working layer consists of diamond particles and a binder. The diamond particles are extremely hard and are the main part used for cutting; the binder firmly bonds the diamond particles to the body, ensuring that the diamond particles do not fall off during cutting. The structure of a typical diamond saw blade is shown in the instruction manual. Figure 1 As shown. When a diamond saw blade is mounted on a cutting device and rotates at high speed, the diamond particles come into contact with the surface of the material being cut. Due to the high hardness of diamond, it can cut into the interior of the material. As the saw blade moves, it gradually cuts the material into the required shape and size. It is widely used in cutting operations such as stone processing, ceramic processing, glass processing, and metal processing.

[0003] like Figure 1 The diamond saw blade shown in the image continuously generates sawdust during cutting, which cannot be effectively discharged and becomes trapped between the diamond and the workpiece at the cutting kerf. This causes the diamond to become stuck, hindering its rotation and potentially leading to the detachment of diamond particles from the saw blade substrate, thus shortening its service life. Simultaneously, because diamond is harder than conventional saw blades, diamond saw blades can achieve higher cutting speeds during cutting, resulting in a corresponding increase in cutting temperature due to high-speed rotary cutting. Currently... Figure 1 The diamond saw blade shown cannot effectively dissipate heat, resulting in excessively high temperatures at the workpiece cutting point, leading to deformation. Summary of the Invention

[0004] To address the aforementioned problems, this application aims to provide a diamond saw blade that facilitates chip removal and cooling, thereby achieving effective chip removal and cooling during workpiece sawing, thus extending the service life of the diamond saw blade and reducing usage costs.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a diamond saw blade that is easy to remove chips and cool down, comprising a saw blade base, on both sides of the saw blade base, with diamond cutting heads provided on both sides of the saw blade base, characterized in that: the diamond cutting heads on both sides of the saw blade base are divided into a first cutting head and a second cutting head along the circumferential spacing, and a first chip removal and cooling groove and a second chip removal and cooling groove are formed between adjacent first cutting heads and second cutting heads, and a third chip removal and cooling groove is also provided outwardly on the first cutting head near the side of the saw blade base.

[0006] Preferably, both the first and second cutting heads are offset from the radial direction of the saw blade base.

[0007] Preferably, the radial width of the first cutting head is greater than the radial width of the second cutting head.

[0008] Preferably, the surfaces of the saw blade base portions of the first and second cutters are both inclined outwards and similarly positioned.

[0009] The beneficial effects of this application are as follows: The diamond saw blade disclosed in this application has a first chip removal and cooling groove and a second chip removal and cooling groove formed on both sides of the saw blade base. During the sawing process, the saw chips generated in contact with the workpiece will enter the first chip removal and cooling groove and the second chip removal and cooling groove, and under the action of centrifugal force, they will be discharged from the outer port of the first chip removal and cooling groove and the second chip removal and cooling groove to the outside of the saw blade, thereby solving the problem of saw chips jamming the rotation of the diamond saw blade; at the same time, under the high-speed rotation of the diamond saw blade, the first chip removal and cooling groove and the second chip removal and cooling groove are used to achieve the cooling effect, solving the problem of high temperature deformation of the workpiece after heat accumulation.

[0010] By setting a third chip removal and cooling groove, the sawdust generated by the saw blade end can be "collected". Together with the first and second chip removal and cooling grooves, it increases the discharge effect of sawdust generated at the saw blade end, so that the part that generates sawdust first can achieve a more effective sawdust discharge.

[0011] The first and second cutting heads are both deflected in the radial direction of the saw blade base. Under the action of centrifugal force, the saw chips are centrifugally discharged in the first chip cooling groove, the second chip cooling groove and the third chip cooling groove. Compared with the radial direction, the saw chips can be discharged quickly under the action of centrifugation.

[0012] Setting the radial width of the first cutter head to be greater than that of the second cutter head can reduce the contact resistance and frictional heating between the second cutter head and the side wall of the saw cut during rotary sawing. At the same time, after the width of the second cutter head is reduced, the width of its second chip removal and cooling groove is also shortened, so that the saw chips on this side can be quickly removed from the saw blade body, achieving the same chip removal effect as the first and third chip removal and cooling grooves on the other side.

[0022] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] See attached document Figures 2-8 The diamond saw blade shown is easy to remove chips and cool down, including a saw blade base 1, on both sides of the saw blade base 1, diamond cutting heads are provided. Currently, conventional diamond saw blades have diamond cutting heads of a certain width provided inward from the side of the saw blade base. Figure 1 As shown in the figure, the sawing operation is achieved by the diamond cutter head rotating and contacting the workpiece at high speed.

[0024] To achieve effective chip removal and cooling at the high rotational speed of the diamond saw blade, such as Figure 2-3As shown, the diamond saw blade disclosed in this application has diamond cutting heads on both sides of the saw blade base 1, which are circumferentially separated into first cutting heads 21 and second cutting heads 22. A first chip removal and cooling groove 2a and a second chip removal and cooling groove 2b are formed between adjacent first cutting heads 21 and second cutting heads 22. During sawing, sawdust generated in contact with the workpiece enters the first chip removal and cooling groove 2a and the second chip removal and cooling groove 2b, and is discharged from the outer port of the first chip removal and cooling groove 2a and the second chip removal and cooling groove 2b to the outside of the saw blade under centrifugal force. After the sawdust enters the first chip removal and cooling groove 2a and the second chip removal and cooling groove 2b, it will not be trapped between the first cutting heads 21 and the second cutting heads 22 and the workpiece, thus solving the problem of sawdust jamming the rotation of the diamond saw blade. Simultaneously, under the high-speed rotation of the diamond saw blade, the first chip removal and cooling groove 2a and the second chip removal and cooling groove 2b achieve a cooling effect, solving the problem of high-temperature deformation of the workpiece after heat accumulation.

[0025] like Figure 4 As shown, during the continuous sawing process of the workpiece, the front ends of the first cutter head 21 and the second cutter head 22 near the saw blade base 1 always preferentially contact the workpiece to cut a kerf. Therefore, this front end will continuously generate a large amount of sawdust. To improve the sawdust removal efficiency, as... Figure 2 , 5 As shown, a third chip removal and cooling groove 2c is also provided outwardly on the first cutter head 21 near the side of the saw blade base, which can "collect" the saw chips generated by sawing at the end of the saw blade. Figure 5 As shown by the middle arrow, the first chip removal cooling groove 2a and the second chip removal cooling groove 2b enhance the chip removal effect on the saw blade cutting end, enabling the part that preferentially generates chips to achieve a more effective chip removal function.

[0026] To further accelerate the discharge of sawdust in the first chip cooling tank 2a, the second chip cooling tank 2b, and the third chip cooling tank 2c, such as Figure 2-3 As shown, both the first cutter head 21 and the second cutter head 22 are offset radially from the saw blade base 1. Figure 6 As shown, when the saw blade rotates in the direction indicated by arrow a, under the action of centrifugal force, the saw chips are centrifugally discharged in the direction indicated by arrow b in the first chip cooling tank 2a, the second chip cooling tank 2b and the third chip cooling tank 2c. Compared with the direction parallel to the radial direction, the saw chips can be discharged quickly under the action of centrifugation ("thrown out").

[0027] During the sawing operation, the first cutter head 21 and the second cutter head 22 are always in rotational contact with the sidewall of the saw cut. Therefore, to reduce this contact resistance, such as Figure 2-3As shown in the comparison, the radial width of the first cutter head 21 is greater than that of the second cutter head 22. The smaller radial width of the second cutter head 22 reduces the width of contact with the sidewall of the saw cut, which reduces the contact resistance and frictional heating between the second cutter head 22 and the sidewall of the saw cut during rotation. At the same time, after the width of the second cutter head 22 is reduced, the width of its second chip removal and cooling groove 2b is also shortened, which allows the saw chips on this side to quickly detach from the saw blade base 1, achieving the same chip removal effect as the first chip removal and cooling groove 2a and the third chip removal and cooling groove 2c on the other side.

[0028] To further enhance the chip removal effect of this diamond saw blade, such as... Figure 7-8 As shown, the surfaces of the saw blade base 1 of the first cutter head 21 and the second cutter head 22 are inclined outwards and similarly arranged (the dotted line in the figure is the horizontal plane of the saw blade base 1). This means that the first chip removal cooling groove 2a, the second chip removal cooling groove 2b, and the third chip removal cooling groove 2c all form an outward-facing slope structure. Under the centrifugal force of sawing, the saw chips in the grooves will be discharged more quickly along the slope structure than the flat groove structure, and will not accumulate. Therefore, the first chip removal cooling groove 2a, the second chip removal cooling groove 2b, and the third chip removal cooling groove 2c of this structure can accelerate the discharge of saw chips and avoid the problem of obstructing the rotation of the saw blade.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
