[0017] This invention also includes a method for preparing an ultra-hard stone grooving and cutting saw blade, the preparation of which includes the following steps:

[0018] Step 1: Saw blade substrate preparation; High-strength alloy steel raw materials are selected, and heat dissipation pipes, air outlets, and limiting rings are set inside. A guide plate and a concentrator plate are reserved at one end of the heat dissipation pipe. After forging and annealing, the center hole and air outlet are machined by CNC milling machine.

[0019] Step 2: Preparation of the cutter head unit:

[0020] 1) To prepare an ultrahard diamond composite layer, diamond particles and Co-Ni-Cu metal binder are mixed evenly in a certain proportion and placed in a mold with pre-reserved slots, openings and protrusions.

This improved heat dissipation enhances chip removal, especially for chips that may remain inside the stone cutting area. The airflow, combined with the chip-collecting groove and the blade itself, effectively removes these chips from the grooved area, facilitating cutting and improving temperature control.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1, as Figures 1-4 As shown, this embodiment proposes an ultra-hard stone grooving and cutting saw blade, including a base 1, a blade body 2 connected to the outer surface of the base 1, a heat dissipation structure 3 provided inside the wall of the base 1, a disassembly structure 4 connecting the blade body 2 and the base 1, and a shock-absorbing structure 5 connected to the surface of the blade body 2; a chip-collecting groove 6 is formed on the surface of the blade body 2, a gasket 7 is detachably connected to the surface of the base 1, a central hole 8 is formed on the outer surface of both the base 1 and the gasket 7, a protruding ring 9 is fixedly connected to one side surface of the central hole 8, the number of protruding rings 9 is several sets, and the spacing between any two adjacent sets of protruding rings 9 is equal, and the angle of the chip-collecting groove 6 is 28°-29°.

[0039] The heat dissipation structure 3 includes a heat dissipation pipe 31 disposed inside the base 1. A limiting ring 32 is fixedly connected inside the heat dissipation pipe 31. An air guide plate 33 is fixedly connected to one end of the base 1 near the heat dissipation pipe 31. An air concentrator plate 34 is fixedly connected to the outer surface of the air guide plate 33.

[0040] An arc-shaped tube 35 is fixedly connected to the outer surface of the heat dissipation pipe 31. An air outlet 36 is opened on the outer surface of the arc-shaped tube 35 and penetrates the base 1. Both ends of the heat dissipation pipe 31 are connected to the outer side of the base 1. The limiting ring 32 is used to reduce the size of the opening cross section of the heat dissipation pipe 31 at this location. The air guide plate 33 is a hollow hemispherical structure. The air concentrator plate 34 is a hollow semi-circular structure. The arc-shaped tube 35 is an arc-shaped structure. There are several groups of air outlets 36. The corresponding air outlets 36 on the same group of arc-shaped tubes 35 are distributed in an array. The spacing between any two adjacent groups of air outlets 36 is equal.

[0041] In this embodiment, during use, the heat transferred from the blade 2 to the base 1 can be effectively dissipated under the rotational force of the base 1. At the same time, the heat dissipation pipe 31 can blow away the waste chips at the end away from the air guide plate 33, thereby achieving a better chip removal effect. Based on heat dissipation, a better chip removal effect can be achieved. In particular, the waste chips that may remain inside the stone cutting part can be effectively discharged from the grooved part by the airflow, in conjunction with the chip groove 6 and the blade 2, making it convenient for the user to cut, and the temperature control effect is better.

[0042] Example 2, as Figures 5-6 As shown, based on Embodiment 1, a connecting groove 41 is provided on the outer surface of the base 1, and a connecting plate 42 is fixedly connected to the end of the blade 2 away from the cutting part. A first hole 43 is provided on the outer surface of the base 1 corresponding to the connecting groove 41. A second hole 44 is provided on the surface of the connecting plate 42. A removable fixing bolt 45 is provided inside the second hole 44. A matching nut 46 is provided on the surface of the fixing bolt 45. Both the first hole 43 and the second hole 44 are matched with the fixing bolt 45. The connecting plate 42 is an arc-shaped plate structure. The connecting plate 42 matches the connecting groove 41, and the fixing bolt 45 matches both the first hole 43 and the second hole 44. The number of the first hole 43 and the second hole 44 are equal, and their positions correspond one-to-one.

[0043] In this embodiment, when the blade body 2 needs to be installed, the user can insert the connecting plate 42 into the hole corresponding to the connecting groove 41. At this time, the blade body 2 together with the connecting plate 42 is initially fixed on the base 1. Then, the user passes the fixing bolt 45 through the first hole 43 and the second hole 44, and then tightens it by rotating the nut 46. The tightening torque is 30 N·m-40 N·m. The nut 46 is a lock-lock nut. Several sets of blade bodies 2 together with the connecting plate 42 can be connected and fixed in the above way. After the fixing is completed, the saw blade can be fixed on the cutting equipment as a whole. By the fit between the washer 7 and the base 1, the convex ring 9 can squeeze the base 1, thereby making the fixed base 1 more stable.

[0044] During use, when a certain set of blades 2 is damaged due to improper cutting or excessive wear, the user can loosen the nut 46 by rotating it to remove the fixing bolt 45 and the nut 46. Then, the blade 2 can be pulled out to the side away from the connecting groove 41, so that the new blade 2 and the connecting plate 42 can be fixedly connected to the base 1 to complete the replacement. This method is suitable for replacing blades 2 when they are partially damaged.

[0045] Example 2, as Figures 7-10As shown, based on embodiment 1 or 2, a shock-absorbing structure 5 is also proposed, including a strip hole 51, an opening 52 and a protrusion 53 respectively opened on the outer surface of the blade body 2. A copper block 54 is provided inside the opening 52. An actuating module 50 is connected to the outer surface of the copper block 54. The actuating module 50 includes a recessed groove 501 opened on the outer surface of the copper block 54. An actuating spring 502 is connected inside the recessed groove 501. An actuating block 503 is connected to one end of the actuating spring 502. An arc-shaped part 504 is fixedly connected to the outer surface of the actuating block 503. Chamfered parts 505 are opened at both ends of the arc-shaped part 504.

[0046] The opening 52 is connected to the protrusion 53 and the strip hole 51. The copper block 54 matches the opening 52. The arc position of the arc part 504 matches the arc surface inside the protrusion 53. The copper block 54 is stabilized by pushing the pushing block 503 through the pushing spring 502. The arc part 504 and the copper block 54 are slidably connected. The sliding direction is the axial direction of the pushing spring 502. The elastic ends of the pushing spring 502 are fixedly connected to the pushing block 503 and the copper block 54 respectively.

[0047] In this embodiment, during installation, the user can press the arc-shaped part 504 to retract the push spring 502, and then insert the copper block 54 into the opening 52. At the same time, under the pushing action of the push spring 502, the arc-shaped part 504 and the blade body 2 can be pushed to a tight state. During the rotation and cutting process of the blade body 2, the vibration generated by the rotation and cutting of the blade body 2 can be greatly reduced. At the same time, the design of the strip hole 51 can reduce the deformation of the blade body 2 after being heated, effectively eliminate stress, and at the same time play a good role in heat dissipation, noise reduction and vibration reduction.

[0048] This invention also includes a method for preparing an ultra-hard stone grooving and cutting saw blade, the preparation of which includes the following steps:

[0049] Step 1: Preparation of saw blade base 1; High-strength alloy steel raw material is selected, and heat dissipation pipe 31, air outlet 36, and limiting ring 32 are set inside. A guide plate 33 and a wind concentrator 34 are reserved at one end of the heat dissipation pipe 31. After forging and annealing, the center hole 8 and air outlet 36 are machined by CNC milling machine. Then, the surface of the base 1 is derusted and passivated for later use.

[0050] Step 2: Preparation of the cutter head unit:

[0051] 1) To prepare an ultrahard diamond composite layer, diamond particles and Co-Ni-Cu metal binder are mixed evenly in a certain proportion and placed in a mold, in which the holes 51, opening 52 and protrusion 53 are reserved. The mold is kept at a temperature of 800℃ and a pressure of 50MPa for 25-35 minutes and then pressed to form a cutting head part composed of a cutting body 2 and a connecting plate 42. The cutting body 2 and the connecting plate 42 are an integrated structure.

[0052] 2) The chip groove 6, the strip hole 51, the opening 52 and the protrusion 53 are made to form the cutter head;

[0053] Step 3: Assembly and Forming: Insert the connecting plate 42 on the blade body 2 into the connecting groove 41. At this time, the connecting plate 42 is initially clamped by the base body 1. Then, the fixing bolt 45 is tightened by passing through the first hole 43 and the second hole 44 and the nut 46 to achieve the connection and fixation between the blade body 2 and the base body 1. Then, insert the copper block 54 into the position corresponding to the opening 52, and at the same time, the protruding position of the arc-shaped part 504 corresponds to the position of the protruding opening 53, so that the saw blade can be formed.

[0054] In summary, the specific operating principle of this invention is as follows:

[0055] During use, when it is necessary to install the blade body 2, the user can insert the connecting plate 42 into the hole corresponding to the connecting groove 41. At this time, the blade body 2 and the connecting plate 42 are initially fixed on the base 1. Then, the user passes the fixing bolt 45 through the first hole 43 and the second hole 44, and then tightens it by rotating the nut 46. The tightening torque is 30 N·m-40 N·m. The nut 46 is a lock-lock nut. Several sets of blade bodies 2 and connecting plates 42 can be connected and fixed in the above way. After the fixing is completed, the saw blade can be fixed on the cutting equipment as a whole. By the fit between the washer 7 and the base 1, the convex ring 9 can squeeze the base 1, so that the fixed base 1 is more stable.

[0056] During use, when a certain set of blades 2 is damaged due to improper cutting or excessive wear, the user can loosen the nut 46 by rotating it to remove the fixing bolt 45 and the nut 46. Then, the blade 2 can be pulled out to the side away from the connecting groove 41, so that the new blade 2 and the connecting plate 42 can be fixedly connected to the base 1 to complete the replacement. This method is suitable for replacing blades 2 when they are partially damaged.

[0057] During the cutting of ultra-hard stone by the rotating saw blade, the base 1 rotates at high speed. The airflow flows into the interior of the heat dissipation pipe 31 under the guidance of the air gathering plate 34 and the air guide plate 33. The airflow flows from the heat dissipation pipe 31 into the interior of the arc-shaped pipe 35 and is finally discharged outward through the air outlet 36. In this process, the heat transferred from the blade 2 to the base 1 can be discharged outward, thereby achieving a high-efficiency heat dissipation effect. At the same time, some airflow will pass through the inside of the limiting ring 32 and finally blow outward from the other end of the heat dissipation pipe 31. During use, the airflow blown outward from one end of the heat dissipation pipe 31 will blow into the gaps in the stone, thereby blowing out the debris in the gaps and achieving a better cleaning effect.

[0058] During installation, the user can press the arc-shaped part 504 to retract the push spring 502, and then insert the copper block 54 into the opening 52. At the same time, under the pushing action of the push spring 502, the arc-shaped part 504 and the blade body 2 can be pushed to a tight state. During the rotation and cutting process of the blade body 2, the vibration generated by the rotation and cutting of the blade body 2 can be greatly reduced. At the same time, the design of the strip hole 51 can reduce the deformation of the blade body 2 after heating, effectively eliminate stress, and at the same time play a good role in heat dissipation, noise reduction and vibration reduction.

[0059] It should be noted that the elastic coefficient of the push spring 502 needs to be adjusted according to the situation after the base 1 and the cutter body 2 are rotated, so as to avoid increased rotational vibration caused by resonance.

[0060] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

A guide plate (33) and a wind concentrator (34) are reserved at one end of the heat dissipation pipe (31). After forging and annealing, the center hole (8) and air outlet (36) are machined by CNC milling machine. Then, the surface of substrate (1) is derusted and passivated for later use. Step 2: Preparation of the cutter head unit: 1) To prepare an ultrahard diamond composite layer, diamond particles and Co-Ni-Cu metal binder are mixed evenly in proportion and placed in a mold, in which the holes of strip hole (51), opening (52) and protrusion (53) are reserved. The mold is kept at 800℃ and 50MPa for 25-35 minutes and then pressed to form a cutting head part composed of cutting body (2) and connecting plate (42). The cutting body (2) and connecting plate (42) are an integrated structure. 2) The chip groove (6), strip hole (51), opening (52) and protrusion (53) are opened to form the cutter head; Step 3: Assembly and shaping: Insert the connecting plate (42) on the blade body (2) into the connecting groove (41). At this time, the connecting plate (42) is initially clamped by the base (1). Then, the fixing bolt (45) is passed through the first hole (43) and the second hole (44) and the nut (46) is tightened to realize the connection and fixation between the blade body (2) and the base (1). Then, insert the copper block (54) into the position corresponding to the opening (52). At the same time, the protruding position of the arc part (504) corresponds to the position of the protruding opening (53), so that the saw blade can be formed.
