Description

Technical Field

[0001] The invention relates to the field of saw blades, and in particular to an elastic electroplated diamond saw blade. Background Art

[0002] Currently, the powder metallurgy saw blades, electroplated coated saw blades, brazed saw blades and other metal-based bonded diamond saw blades for cutting non-metallic brittle and hard material plates on the market have rigid teeth, which are prone to rigid impact cutting and extrusion cutting edge collapse during cutting; the saw blades are mostly cooled by external cooling mode during operation. Under the action of centrifugal force, the saw blade cooling water is basically in an atomized state, and its cooling effect is poor; a large number of exposed diamonds are distributed on the outer surface of the saw blade, forming a chip / water holding space, but the powder chips in the space are very likely to be blocked and accumulated, causing chip blockage; At the same time, due to the presence of dust, friction is generated between the workpiece and the binder, which increases the processing load. The grinding and scouring effect of dust on the binder also causes unnecessary wear of the binder, which affects the life of the saw blade. In order to meet the needs of high chip capacity and water carrying, and to reduce the wear of the binder, coarse-grained diamonds are usually used to facilitate the height of diamond exposure and make the chip / water holding space larger. However, large-grained diamonds will increase the area of ​​diamond passivation during the diamond passivation process. In order to obtain the necessary pressure for the diamond to perform the engraving work, it is necessary to increase the pressure on the metal. The positive pressure of diamond can be completed, and the increase of positive pressure can easily cause the edge collapse of the workpiece. The edge collapse problem is one of the most difficult problems to solve when saw blades cut plates; the circumferential edges and corners of the two end faces of the saw blade are affected by the forces in the circumferential, radial and axial directions, which can easily cause large arc surfaces, increasing the unfavorable factors causing edge bursting when sawing workpieces and reducing the technical performance of the saw blade; the diamond saw blade with metal-based binder (such as powder metallurgy metal powder) can only work normally when the diamond particles on its working surface are held and consolidated by the binder. The volume of the binder is several times or even dozens of times the total volume of diamond, resulting in high material costs. During the self-sharpening process of the saw blade, a large amount of excessive binder needs to be worn away, resulting in high friction heat. For the saw blade to work normally, the wear rate of the binder needs to be adapted to the wear rate of the diamond. Therefore, the hardness of the binder is often limited by the self-sharpening requirements. It is easy for the diamond particles to squeeze the binder under the action of force, causing the binder to undergo plastic deformation, and then the proportion of unnecessary diamond shedding increases. The above unfavorable factors directly affect the high-quality high-speed processing of the saw blade. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide an elastic electroplated diamond saw blade to solve the above problems when there are quality requirements for edge chipping (including situations where there are quality requirements for edge chipping on the upper surface of the workpiece, such as road cutting, workpiece grooving, etc.).

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an elastic electroplated diamond saw blade, comprising: a plurality of elastic teeth with elasticity and a saw blade base, wherein the plurality of elastic teeth are circumferentially assembled and fixed on the outer peripheral surface of the saw blade base, and the axial thickness of the elastic teeth is greater than the axial thickness of the saw blade base; the elastic teeth include a tooth base and a diamond coating layer, and the diamond coating layer is fixed on the working section of the tooth base, and the multiple diamond particles exposed on the outer peripheral surface of the saw blade in the working section are smoothly connected one by one along the axial direction to form a curved structure, and the two diamond particles located at the two axial ends of the curved structure are at the same azimuth angle.

[0005] The beneficial effects of the present invention are as follows: a plurality of elastic teeth are assembled and fixed on the outer periphery of the saw blade base, which is beneficial to avoiding or alleviating the occurrence of rigid impact-induced edge chipping at the entry of the cutting end face and extrusion-induced edge chipping at the exit of the cutting end face through the elastic deformation or elastic displacement of the elastic teeth when cutting the workpiece; since the azimuth angle of the exposed diamond (i.e., working diamond) on the outer periphery of the elastic teeth is within a certain range of values, the pressure on the workpiece is also decomposed within a range during cutting, which is beneficial to reducing or alleviating the influence of positive pressure on edge chipping; the two diamond particles at the axial ends of the curved structure are at the same azimuth angle, and at the moment of contact (cutting into) with the workpiece, the single diamond particles at both ends are in a high-pressure "sharp" cutting state. The above structural design is beneficial to reducing the edge chipping of the workpiece at the cutting-in or cutting-out end, and has centering effect. The axial thickness of the elastic teeth is greater than the axial thickness of the saw blade base, which is conducive to forming a water channel for cooling water between the saw blade base and the elastic teeth, so that the cooling water enters between the elastic teeth and the workpiece under the action of centrifugal force, cools the working diamond particles, and realizes an efficient cooling structure with water channels between each single layer of diamond in the circumferential direction. At the same time, the structure also has the function of quickly accommodating powder chips and discharging powder chips under the action of centrifugal force and cooling water, thereby realizing the function of grinding, cooling and chip removal, and is also conducive to preventing the occurrence of carding during saw blade processing. The method of assembling and consolidating elastic teeth to manufacture saw blades can reduce process difficulty, improve manufacturing efficiency, and reduce the use of diamond and binder materials, thereby reducing costs.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the curved structure is formed by connecting straight lines, connecting straight lines and arcs, or connecting arcs and arcs.

[0008] The beneficial effects of adopting the above further scheme are: adjusting the curvature of each point in the curve structure, that is, the different shapes of the special-shaped surfaces, can adjust the axial spacing of the exposed diamond particles, and then adjust the wear rate of each axial point, thereby maintaining the sharp edges of the elastic teeth and adjusting the proportion of mechanical crushing work; the symmetrical curve structure is suitable for plate cutting, and the asymmetrical curve structure is suitable for plate trimming.

[0009] Furthermore, the two diamond particles located at the two axial ends of the curved structure are symmetrically or asymmetrically arranged.

[0010] The beneficial effect of adopting the above further solution is that when processing a workpiece, if the two diamond particles located at the axial ends of the curved structure are symmetrically arranged, the two diamond particles contact the workpiece at the same time, which is suitable for plate cutting. If the arrangement is asymmetrical, the diamond particles at one end contact the workpiece first, which is suitable for plate trimming.

[0011] Furthermore, the tooth base also includes an assembly section and an elastic section, the assembly section and the working section are arranged in a one-to-one correspondence at both ends of the elastic section, at least one circumferential surface of the working section is a special-shaped surface, and the diamond coating layer is solidified on the special-shaped surface of the working section.

[0012] The beneficial effect of adopting the above further solution is that it is beneficial to avoid or alleviate the entry edge chipping of the rigid impact cutting end face and the exit edge chipping of the extrusion cutting end face through the elastic deformation or elastic displacement of the elastic section when cutting the workpiece.

[0013] Furthermore, along the processing rotation direction of the saw blade, the diamond coating layer is solidified on one side or both sides of the circumferential profiled surface of the working section.

[0014] The beneficial effect of adopting the above further solution is that it is helpful to select a suitable working surface according to different processing requirements in different embodiments, thereby further adjusting the service life of the saw blade.

[0015] Furthermore, the diamond coating layer further includes a binder, a plurality of diamond particles are circumferentially arranged in a single layer in the binder, the diamond particles are consolidated on the profiled surface of the working section through the binder, and the circumferential thickness of the binder is greater than the particle size of the diamond particles.

[0016] The beneficial effects of adopting the above further solution are: the binder has a high holding force, and multiple diamond particles are arranged in a circumferential single layer in the binder, which is beneficial to improving the life, reducing the overall concentration of diamond particles on the saw blade, and achieving low-load processing.

[0017] Furthermore, a plurality of mounting grooves are provided on the outer circumference of the saw blade base, the depth of the mounting grooves in the radial direction of the saw blade is less than 100 mm, the mounting grooves are transitioned to the outer circumference of the saw blade base in an arc, and the assembly section is welded and fixed in the mounting grooves.

[0018] The beneficial effects of adopting the above-mentioned further scheme are: the depth setting of the mounting groove in the radial direction of the saw blade is conducive to ensuring that the mounting groove and the assembly section of the elastic tooth have sufficient welding length, thereby ensuring the welding strength; the outer circular arc transition setting of the mounting groove and the saw blade base is conducive to preventing the elastic section of the elastic tooth from breaking due to extrusion and wear during elastic deformation; welding is conducive to ensuring the welding strength of the assembly section and the mounting groove, and is conducive to efficient processing.

[0019] Furthermore, along the processing rotation direction of the saw blade, the tooth base is arranged behind the diamond coating layer.

[0020] The beneficial effect of adopting the above further solution is: it is conducive to placing the tooth base in a back-to-back position during processing, and by using an elastic hard base to support the main grinding force of the diamond particles, it is conducive to reducing the shedding rate of the diamond particles and increasing the life of the saw blade.

[0021] Furthermore, the ratio of the sum of the circumferential arc lengths of the diamond particles of the plurality of elastic teeth on the outer peripheral surface of the saw blade to the outer circumference of the saw blade is less than 50%.

[0022] The beneficial effects of adopting the above further solution are: reducing friction resistance, saving binder materials, and reducing material costs.

[0023] Furthermore, along the length direction of the elastic tooth, the extension line of the elastic tooth passes through the center of the saw blade or is eccentrically arranged with respect to the center of the saw blade.

[0024] The beneficial effect of adopting the above further scheme is: it is conducive to adjusting the proportion of diamonds involved in cutting by the elastic teeth by adjusting the inclination angle of the elastic teeth on the periphery of the saw blade base in different embodiments, thereby adjusting the deformation of the elastic teeth and further adjusting the life of the saw blade.

[0028] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] like Figures 1 to 33 As shown, an elastic electroplated diamond saw blade comprises: a plurality of elastic teeth 1 with elasticity and a saw blade base 2, wherein the plurality of elastic teeth 1 are circumferentially arranged, assembled and fixed on the outer peripheral surface of the saw blade base 2, and the axial thickness H of the elastic teeth 1 is greater than the axial thickness H1 of the saw blade base 2; the elastic teeth 1 comprise a tooth base 11 and a diamond coating layer 12, and the diamond coating layer 12 is fixed on the working section 113 of the tooth base 11, and the multiple diamond particles 122 exposed on the outer peripheral surface of the saw blade of the working section 113 are smoothly connected one by one along the axial direction to form a curved line structure, and the two diamond particles 122 located at the two axial ends of the curved structure are at the same azimuth angle.

[0030] It should be noted that: in the technical solution of the present invention, the expressions of axial, radial, circumferential and other directions are based on the saw blade; “The working section 113 on the outer peripheral surface of the saw blade” refers to the end surface of the elastic tooth 1 that is not assembled and connected to the saw blade base 2; like Figure 13 As shown, the azimuth angles of the plurality of diamond particles 122 (i.e., working diamond particles) exposed on the outer peripheral surface of the saw blade by the working segment 113 are within a certain range. When the plurality of elastic teeth 1 come into contact with the workpiece as the saw blade rotates, the plurality of diamond particles 122 (i.e., working diamond particles) exposed on the outer peripheral surface of the saw blade by the working segment 113 are not all in contact with the workpiece at a certain moment, but gradually come into contact with the workpiece along the rotation direction of the saw blade, i.e., the plurality of diamond particles 122 gradually come into contact with the workpiece. Figure 13 The diamond particles 122 indicated at E in the figure come into contact with the workpiece first, and the diamond particles 122 indicated at F come into contact with the workpiece later. This is beneficial for gradually applying pressure to the workpiece during cutting, thereby decomposing the pressure on the workpiece and alleviating the effect of positive pressure on edge chipping. like Figure 25 and Figure 26 As shown in FIG, “the same azimuth angle” means that the line connecting the two diamond particles 122 at the two ends of the axial direction in the curved structure is parallel to the axis of the saw blade. Figure 25 In the figure, the vertical dotted line represents the axis of the saw blade, and the line connecting the two diamond particles 122 at the two axial ends in the curved structure is represented by a solid line parallel to the dotted line. For a clearer understanding, the line connecting the two diamond particles 122 at the two axial ends in the curved structure is extended toward the two axial ends. Figure 25 For an ideal assembly situation, when viewed from the axial direction, the diamond coating layers 12 at both ends of the curved structure just overlap, as shown in FIG. Figure 26 As shown; However, since the elastic teeth 1 cannot be completely assembled in an ideal state, and the diamond particles 122 do not fall off at the same time, there will be a certain error due to the misalignment of the elastic teeth 1 and the saw blade base 2 during assembly, or because the diamond particles 122 do not fall off at the same time, then there will be a problem such as Figure 27 In the case shown, the diamond coating layers 12 at both ends of the curved structure are misaligned when viewed from the axial direction, and the diamond coating layers 12 at both ends of the curved structure can be seen at the same time. Therefore, in the technical solution of the present invention, "the same azimuth angle" includes its allowable tolerance, which is the azimuth angle corresponding to ±3 times the arc length of the diamond particle diameter at the two diamond particles 122 at the two ends of the curved structure; like Figure 27 As shown, the arc length L represents the arc length of the exposed area of ​​the diamond coating layer 12 at one end of the axial direction in the curved structure in the circumferential direction of the saw blade.， The arc length of the exposed area of ​​the diamond coating layer 12 at the other end of the axial direction in the curved structure is L and L ， are less than or equal to three times the particle size of the diamond particles 122; Figure 28 As shown, the dotted line and the dashed line represent the error range of the diamond coating layer 12, δ and δ ， The angles between the diamond coating layer 12 and the saw blade axis after the misalignment, δ and δ ， The azimuth angle is equal to 3 times the arc length of the diamond particle diameter; The working section 113 is made of a hard matrix. That is, the hardness of the working section 113 must meet the following requirements: when supporting the diamond particles 122 under working force, the diamond particles 122 will not be squeezed and deformed. This will greatly improve the utilization rate of the diamond particles, reduce the requirements for the binder's ability to hold the diamond particles, facilitate the adjustment of the saw blade's self-sharpening properties, and increase the life of the saw blade. The tooth base 11 is made of a spring steel elastic material of appropriate thickness, which is conducive to ensuring the elasticity and strength of the elastic tooth 1. For example, the material is 65 manganese spring steel plate, which is conducive to ensuring fatigue strength. For saw blades for cutting panels with smaller thickness, the elastic teeth 1 can be fixed to the saw blade base 2 by mechanical assembly or clamping, eliminating the problem of thermal deformation caused by welding affecting accuracy and the difficulty of ensuring accuracy.

[0031] The beneficial effects of the present invention are as follows: a plurality of elastic teeth are assembled and fixed on the outer periphery of the saw blade base, which is beneficial to avoiding or alleviating the occurrence of rigid impact-induced edge chipping at the entry of the cutting end face and extrusion-induced edge chipping at the exit of the cutting end face through the elastic deformation or elastic displacement of the elastic teeth when cutting the workpiece; since the azimuth angle of the exposed diamond (i.e., working diamond) on the outer periphery of the elastic teeth is within a certain range of values, the pressure on the workpiece is also decomposed within a range during cutting, which is beneficial to reducing or alleviating the influence of positive pressure on edge chipping; the two diamond particles at the axial ends of the curved structure are at the same azimuth angle, and at the moment of contact (cutting into) with the workpiece, the single diamond particles at both ends are in a high-pressure "sharp" cutting state. The above structural design is beneficial to reducing the edge chipping of the workpiece at the cutting-in or cutting-out end, and has centering effect. The axial thickness of the elastic teeth is greater than the axial thickness of the saw blade base, which is conducive to forming a water channel for cooling water between the saw blade base and the elastic teeth, so that the cooling water enters between the elastic teeth and the workpiece under the action of centrifugal force, cools the working diamond particles, and realizes an efficient cooling structure with water channels between each single layer of diamond in the circumferential direction. At the same time, the structure also has the function of quickly accommodating powder chips and discharging powder chips under the action of centrifugal force and cooling water, thereby realizing the function of grinding, cooling and chip removal, and is also conducive to preventing the occurrence of carding during saw blade processing. The method of assembling and consolidating elastic teeth to manufacture saw blades can reduce process difficulty, improve manufacturing efficiency, and reduce the use of diamond and binder materials, thereby reducing costs.

[0032] Preferably, Figures 16 to 23 、 Figures 29 to 32 As shown, the curved structure is formed by connecting straight lines, connecting straight lines and arcs, or connecting arcs and arcs.

[0033] It should be noted that the range included in the axial direction of the curved structure is the range of the axial azimuth angles of the multiple diamond particles 122 (ie, working diamond particles) exposed on the outer peripheral surface of the saw blade by the working segment 113 .

[0034] The beneficial effect of adopting the above preferred solution is that by adjusting the curvature of each point in the curved structure, that is, the different shapes of the special-shaped surfaces, the axial spacing of the exposed diamond particles can be adjusted, and then the wear rate of each axial point can be adjusted, thereby maintaining the sharp edges of the elastic teeth and adjusting the proportion of mechanical crushing work.

[0035] Preferably, Figures 16 to 23 、 Figures 29 to 32 As shown, the two diamond particles 122 at the two axial ends of the curved structure are symmetrically or asymmetrically arranged.

[0036] It should be noted that the two diamond particles 122 located at the two axial ends of the curved structure are symmetrically arranged or asymmetrically arranged with respect to the circumferential surface of the saw blade.

[0037] The beneficial effect of adopting the above preferred scheme is that when processing a workpiece, if the two diamond particles located at the axial ends in the curved structure are symmetrically arranged, the two diamond particles contact the workpiece at the same time, which is suitable for plate cutting. If the arrangement is asymmetrical, the diamond particles at one end contact the workpiece first, which is suitable for plate trimming.

[0038] Preferably, Figure 6 、 Figure 7 、 Figure 9 and Figure 15 As shown, the tooth base 11 further includes an assembly segment 111 and an elastic segment 112. The assembly segment 111 and the working segment 113 are arranged at both ends of the elastic segment 112 in a one-to-one correspondence. At least one circumferential surface of the working segment 113 is a special-shaped surface, and the diamond coating layer 12 is solidified on the special-shaped surface of the working segment 113.

[0039] Among them, it should be noted that: in a preferred embodiment of the present invention, the diamond coating layer 12 is electroplated on the special-shaped surface of the working section 113, and brazing / additive processing technology can also be used to replace the entire or partial electroplating, which is beneficial to improving the service life; powder metallurgy can also be combined with the tooth base 11 to replace electroplating; partial electroplating and partial powder metallurgy can also be combined, which is beneficial to the low-cost manufacturing of coarse-grained diamonds.

[0040] The beneficial effect of adopting the above preferred solution is that it is beneficial to avoid or alleviate the entry edge chipping of the rigid impact cutting end face and the exit edge chipping of the extrusion cutting end face through the elastic deformation or elastic displacement of the elastic section when cutting the workpiece.

[0041] Preferably, Figure 7 and Figure 15 As shown, along the processing rotation direction of the saw blade, the diamond coating layer 12 is coated on one side or both sides of the circumferential profiled surface of the working section 113 .

[0042] It should be noted that: in the technical solution of the present invention, it is intended to be arranged on the circumferential profiled surfaces on both sides of the working section 113 only when the saw blade life is required to be high; The circumferential surface of the working section 113 refers to the front side and the rear side of the working section 113 along the processing rotation direction of the saw blade. Figure 15 As shown, the diamond coating layer 12 is coated on both the front side and the rear side of the working section 113; The irregular surface is concave, convex or flat from a macroscopic perspective, and is a surface formed by a combination of concave, convex and flat surfaces from a microscopic perspective, such as an irregular wavy surface. When the requirements for edge chipping are not high, the circumferential surface of the working section 113 can be set as a plane, and the diamond coating layer 12 is provided on a single side wall of the circumferential plane of the working section 113, which is simple in process and low in cost.

[0043] The beneficial effect of adopting the above preferred solution is that it is conducive to selecting a suitable working surface according to different processing requirements in different embodiments, thereby further adjusting the service life of the saw blade.

[0044] Preferably, Figure 7 and Figure 15 As shown, the diamond coating layer 12 further includes a binder 121, and a plurality of diamond particles 122 are circumferentially arranged in a single layer in the binder 121. The diamond particles 122 are consolidated on the profiled surface of the working section 113 through the binder 121. The circumferential thickness h of the binder 121 is greater than the particle size b of the diamond particles 122.

[0045] The beneficial effects of adopting the above preferred solution are: the binder has high holding force, and multiple diamond particles are arranged in a single layer in the circumferential direction in the binder, which is beneficial to improving the service life, reducing the overall concentration of diamond particles on the saw blade, and realizing low-load processing.

[0046] Preferably, Figure 5 As shown, a plurality of mounting grooves 21 are provided around the outer periphery of the saw blade base 2, the radial depth H2 of the mounting groove 21 is less than 100 mm, the mounting groove 21 is transitionally arranged with an arc around the outer periphery of the saw blade base 2, and the assembly section 111 is welded and fixed in the mounting groove 21.

[0047] It should be noted that the elastic section 112 is located between the assembly section 111 and the working section 113 and is mostly located outside the outer peripheral surface of the saw blade base 2, which is conducive to the elastic deformation or elastic displacement of the elastic teeth 1 when subjected to force, thereby avoiding or alleviating the occurrence of inlet edge collapse of the rigid impact cutting end face and outlet edge collapse of the extrusion cutting end face; The assembly section 111 is fixed in the installation groove 21 by laser welding or various brazing methods.

[0048] The beneficial effects of adopting the above-mentioned preferred scheme are: the depth setting of the mounting groove in the radial direction of the saw blade is conducive to ensuring that the mounting groove and the assembly section of the elastic tooth have sufficient welding length, ensuring the welding strength; the outer circular arc transition setting of the mounting groove and the saw blade base is conducive to preventing the elastic section of the elastic tooth from breaking due to extrusion and wear during elastic deformation; welding is conducive to ensuring the welding strength of the assembly section and the mounting groove, and is conducive to efficient processing.

[0049] Preferably, Figure 13 As shown, along the processing rotation direction of the saw blade, the tooth base 11 is arranged behind the diamond coating layer 12.

[0050] The beneficial effects of adopting the above preferred solution are: it is conducive to placing the tooth base in a back-to-back position during processing, and by using an elastic hard base to support the main grinding force of the diamond particles, it is conducive to reducing the shedding rate of the diamond particles and increasing the life of the saw blade.

[0051] Preferably, Figure 4 As shown, the ratio of the sum of the circumferential arc lengths of the diamond particles 122 of the plurality of elastic teeth 1 on the outer peripheral surface of the saw blade to the outer peripheral length of the saw blade is less than 50%.

[0052] It should be noted that: in the technical solution of the present invention, the circumferential arc length L1 of the diamond particles 122 of each elastic tooth 1 on the periphery of the saw blade (approximately equal to the circumferential thickness of the binder 121) multiplied by the number of the elastic teeth 1 is the sum of the circumferential arc lengths of the diamond particles 122 of multiple elastic teeth 1 on the periphery of the saw blade.
