Description

Technical Field

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

[0002] The diamond cutting tip is the working body of a diamond saw blade. It consists of diamond and a matrix binder. Diamond, a superhard material, acts as the cutting edge, while the matrix binder holds the diamond in place. The binder is composed of elemental metal powder or metal alloy powder; different compositions are called formulations, and these formulations differ depending on the application. The manufacturing process of a diamond saw blade cutting tip can be described as a sintering process of metal powder under certain pressure. This is a powder metallurgy process. Under high temperature (800-1000°C) and certain pressure (180-250 kgf / cm²), the metal powder undergoes a series of physicochemical processes such as diffusion, welding, combination, and recrystallization between powder particles to form a sintered body with a specific shape and mechanical properties—the cutting tip.

[0003] Diamond saw blades are widely used in the ceramics and stone processing industries due to their superior cutting and grinding performance. The diamond saw blade is typically fixed to the blade body by welding. However, due to the rapid wear of the blade during cutting, its sharpness decreases quickly, necessitating frequent blade replacements to restore cutting sharpness. This undoubtedly increases cutting costs, especially when using large diamond saw blades, where the costs are even higher. Utility Model Content

[0004] The purpose of this utility model is to provide a diamond saw blade with a replaceable blade head 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 diamond saw blade with replaceable blade head includes a saw blade base. The surface of the saw blade base is provided with a plurality of heat dissipation grooves arranged in a circumferential array at the edge. Each heat dissipation groove is provided with a noise reduction block at one end of the center part of the saw blade base. A fixing seat is formed between each pair of adjacent heat dissipation grooves. Each fixing seat can be connected to a mounting seat that is detachably connected to it. A blade head is provided on the side of the mounting seat away from the saw blade base. A groove is provided in the middle part of one side wall of the blade head, and both sides of the blade head are provided with protruding edges.

[0006] Preferably, the fixing base has a U-shaped opening in the middle, and a plug is provided in the middle of the U-shaped opening. The mounting base has sockets distributed corresponding to the plug, the size of the plug matches the size of the socket, and the surface of the plug has a fixing hole. The surface of the mounting base has threaded holes distributed corresponding to the fixing holes, and the surface of the mounting base has countersunk holes concentric with the threaded holes. Screws are fixedly connected to the threaded holes and the fixing holes.

[0007] Preferably, the two side walls of the U-shaped opening are provided with limit strips on both sides of the insertion block, and the two side walls of the mounting base are provided with limit grooves corresponding to the limit strips on both sides of the insertion opening. The size of the limit strip matches the size of the limit groove, and the end of the limit groove away from the cutter head is an open structure.

[0008] Preferably, the groove is an isosceles trapezoidal structure, and the grooves on two adjacent cutter heads are oriented in opposite directions.

[0009] Preferably, the convex edge is configured as a bevel.

[0010] Preferably, a notch is formed between each pair of adjacent cutting heads.

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

[0012] 1. This utility model restricts the movement of the cutter head in six directions (front-back, left-right, up-down) through the cooperation between the socket on the mounting base and the U-shaped socket, and with the action of the threaded hole, fixing hole, and screw. This achieves a tight fixation of the cutter head, effectively preventing it from loosening, ensuring structural stability, and preventing interference between the cutter heads. When a cutter head is severely worn, it can be disassembled and replaced individually, greatly saving costs and reducing resource waste. Disassembly is also convenient, avoiding frequent replacement of the cutter head, reducing labor intensity, and making it highly practical.

[0013] 2. This utility model, through the groove design on the cutter head, can ensure the effective removal of cooling water and cutting residue. In addition, because the area where cooling water can reach the cutter head is increased, the cooling effect is enhanced, and the damage to the cutter head caused by the heat generated during cutting is reduced. This extends the cutting life of the cutter head. Furthermore, the convex edge reduces friction between the cutter head and the workpiece, lowers cutting heat, and prevents saw jamming, making the sawing process smoother and further extending the service life of the cutter head.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a diamond saw blade with a replaceable blade head.

[0028] like Figure 1-6As shown, this utility model discloses a diamond saw blade with replaceable blade head, comprising a saw blade base 1. Multiple heat dissipation grooves 2 arranged in a circular array are provided on the surface of the saw blade base 1 along its edge. A noise reduction block 3 is provided at one end of the center of each heat dissipation groove 2. A fixing seat 6 is formed between every two adjacent heat dissipation grooves 2. Each fixing seat 6 can be detachably connected to a mounting seat 4. A blade head 5 is provided on the side of the mounting seat 4 away from the saw blade base 1. A notch is formed between every two adjacent blade heads 5. A U-shaped opening 7 is provided in the middle of the fixing seat 6. An insertion block 8 is provided in the middle of the U-shaped opening 7. Inserts 11 corresponding to the insertion blocks 8 are provided on the mounting seat 4. The size of the insertion blocks 8 matches the size of the inserts 11, and the surface of the insertion blocks 8 is provided with fixing holes 10. The surface of the mounting seat 4 is provided with threaded holes 13 corresponding to the fixing holes 10. A countersunk hole 14 concentric with the threaded hole 13 is provided. Screws are fixedly connected to the threaded hole 13 and the fixing hole 10. Through the cooperation between the insertion port 11 on the mounting base 4 and the insertion block 8 on the U-shaped port 7, when installing the cutter head 5, simply align the insertion port 11 and the insertion block 8 and insert them. This will restrict the front-back and left-right directions of the cutter head 5. Align the threaded hole 13 with the fixing hole 10 and tighten the screw between the threaded hole 13 and the fixing hole 10 to lock and fix the mounting base 4. This will restrict the up-down direction of the cutter head 5, thereby achieving a tight fixation of the cutter head 5. This can effectively prevent the cutter head 5 from loosening, ensure the stability of the structure, and ensure that each cutter head 5 does not interfere with each other. When a cutter head is severely worn, it can be disassembled and replaced individually, which greatly saves costs and reduces the waste of resources. Disassembly is convenient, avoids frequent replacement of the cutter head, reduces labor intensity, and is highly practical. Limiting strips 9 are provided on both sides of the U-shaped opening 7 on both sides of the insertion block 8. Limiting grooves 12 corresponding to the limiting strips 9 are provided on both sides of the mounting base 4 on both sides of the insertion opening 11. The size of the limiting strips 9 matches the size of the limiting grooves 12, and the end of the limiting groove 12 away from the cutter head 5 is an open structure. Through the cooperation between the limiting strips 9 and the limiting grooves 12, when the insertion opening 11 is aligned with the insertion block 8, the limiting strips 9 and the limiting grooves 12 are aligned, which further limits the mounting base 4, making the connection between the mounting base and the U-shaped opening 7 more tight and firm.

[0029] A groove 16 is provided in the middle of one side wall of the cutter head 5. The groove 16 is an isosceles trapezoidal structure, and the grooves 16 on two adjacent cutter heads 5 are oriented in opposite directions. Since the volume to be cut in the middle section of the cutter head 5 is less than that on the sides of the cutter head 5 during the cutting process, the middle section of the cutter head 5 wears faster, but the same cutting performance can be obtained. Since there is no working surface in the groove 16 of the cutter head 5, the wear of the cutter head 5 becomes more even. Since the groove 16 runs through the entire height of the cutter head 5, it can ensure the effective removal of cooling water and cutting residue. In addition, since the area where cooling water can reach the cutter head 5 is increased, the cooling effect is increased, and the heat generated during cutting can also reduce the damage to the cutter head 5, thus extending the cutting life of the cutter head 5. Both ends of the cutter head 5 are provided with protruding edges 15. The protruding edges 15 are set as bevels. By setting the protruding edges 15, a side clearance is generated between the cutter head 5 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 5 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 5.

[0030] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
