Description

Technical Field

[0001] This utility model relates to the field of diamond saw blade technology, specifically to a threaded flange quick-release diamond saw blade. Background Technology

[0002] A diamond saw blade is a cutting tool used for processing hard and brittle materials. It mainly consists of two parts: a base and a blade head. The base is the main supporting part for bonding the blade head. In actual use, the diamond saw blade needs to be connected to the output end of the cutting device through a flange to ensure the stability of the saw blade when rotating at high speed.

[0003] Currently, diamond saw blades are generally connected to flanges using spot welding. However, the high temperatures during spot welding can alter the local properties of the substrate, causing stress concentration and reducing the overall structural strength of the saw blade. Furthermore, spot welding is a permanent fixation, which can lead to resource waste. Some saw blades use multi-bolt flange connections, but these require 8-12 bolts for circumferential fixation, resulting in time-consuming assembly and disassembly, and demanding high precision in bolt hole positioning.

[0004] Therefore, this utility model proposes a quick-release diamond saw blade with a threaded flange to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-release diamond saw blade with a threaded flange, which solves the problems of time-consuming disassembly and assembly and reduced overall structural strength of the saw blade in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A quick-release diamond saw blade with a threaded flange includes a saw blade base, a threaded flange, and diamond cutting heads. The diamond cutting heads are evenly connected to the outer peripheral edge of the saw blade base. A central mounting hole is formed in the center of the saw blade base, and a threaded flange is connected within the central mounting hole. The threaded flange includes an upper flange and a lower flange. The upper flange is detachably connected to the central mounting hole. A locating pin is provided on the saw blade base, and a locating groove is formed on the upper flange corresponding to the locating pin. The lower flange is coaxially connected to the upper flange. The inner ring of the upper flange is provided with an internal thread, and the outer ring of the lower flange is provided with an external thread that mates with the internal thread. Multiple arrow-shaped protrusions are circumferentially arranged on the outer circular surfaces of both the upper and lower flanges, with the tips of the arrow-shaped protrusions all pointing outwards.

[0008] By adopting the above technical solution, the internal thread of the upper flange and the external thread of the lower flange mate, enabling quick assembly and disassembly of the saw blade base and the equipment spindle. The lower flange can be separated by rotating it in the opposite direction, allowing for rapid disassembly of the saw blade base. The positioning pin of the saw blade base mates with the positioning groove of the upper flange, achieving precise positioning during installation.

[0009] Furthermore, the bottom of the upper flange is connected to an anti-loosening boss, and the top of the lower flange is correspondingly provided with an anti-loosening groove, the anti-loosening boss and the anti-loosening groove cooperating with each other.

[0010] By adopting the above technical solution, the connection of the saw blade base can be prevented from loosening under high-speed cutting vibration, thus ensuring operational safety.

[0011] Furthermore, a damping rubber ring is provided between the upper flange and the saw blade base, and the damping rubber ring is connected in an annular groove on the outer circumferential surface of the upper flange.

[0012] By adopting the above technical solutions, the damping rubber ring can reduce vibration and noise.

[0013] Furthermore, an installation groove is provided on the bottom surface of the lower flange.

[0014] By adopting the above technical solution, it is easy to accurately connect the saw blade base with the equipment spindle, thus ensuring the stability of the installation.

[0015] Furthermore, the outer peripheral edge of the saw blade substrate has a continuous convex structure, and the inner peripheral edge of the diamond cutting head is correspondingly set as a continuous concave structure. The saw blade substrate and the diamond cutting head are fitted and connected. The upper and lower surfaces of the diamond cutting head are respectively provided with a plurality of uniformly distributed reinforcing blocks. The reinforcing blocks have a parallelogram structure and are inclined to the radial direction of the saw blade substrate.

[0016] By adopting the above technical solutions, the structural strength of the diamond cutting tip can be enhanced, the stress generated during the cutting process can be dispersed, and the damage to the diamond cutting tip due to uneven stress can be reduced.

[0017] Furthermore, the saw blade substrate is provided with multiple through holes, which are evenly distributed on the outer periphery of the mounting center hole.

[0018] By adopting the above technical solution, the powder and debris generated during the cutting process can be quickly discharged through the through hole, avoiding debris accumulation and accelerating the dissipation of heat from the substrate during cutting.

[0019] Furthermore, the saw blade base, upper flange, and lower flange are all made of high-strength alloy steel, and the diamond cutting head is made of diamond composite sheet.

[0020] By adopting the above technical solutions, the system can withstand high-speed rotation and friction, ensuring the strength of the base structure and improving operational efficiency.

[0021] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The saw blade base positioning pin of this utility model cooperates with the upper flange positioning groove to achieve precise positioning during installation. The internal thread of the upper flange cooperates with the external thread of the lower flange to realize quick assembly and disassembly of the saw blade base and the main shaft of the equipment. The lower flange can be separated by rotating it in the opposite direction, which facilitates the disassembly of the saw blade base.

[0023] 2. The diamond cutter head of this utility model is made of diamond composite sheet, which has extremely high hardness and wear resistance. Multiple parallelogram-shaped reinforcing blocks are set on the upper and lower surfaces of the diamond cutter head and are inclined to the radial direction of the saw blade base. During cutting, the diamond cutter head can enhance the structural strength of the diamond cutter head, disperse the stress generated during the cutting process, reduce the damage of the diamond cutter head due to uneven stress, and improve the service life of the saw blade base.

[0033] like Figure 1-6 As shown, a quick-release diamond saw blade with a threaded flange includes a saw blade base 1, a threaded flange, and a diamond cutting head 3. The diamond cutting head 3 is uniformly connected to the outer peripheral edge of the saw blade base 1. The outer peripheral edge of the saw blade base 1 has a continuous convex structure, and the inner peripheral edge of the diamond cutting head 3 is correspondingly set as a continuous concave structure. The saw blade base 1 and the diamond cutting head 3 are fitted together. Multiple uniformly distributed reinforcing blocks 4 are respectively provided on the upper and lower surfaces of the diamond cutting head 3. The reinforcing blocks 4 have a parallelogram structure and are inclined to the radial direction of the saw blade base 1.

[0034] Furthermore, a central mounting hole 5 is provided in the middle of the saw blade base 1, and multiple through holes 2 are provided on the saw blade base 1, which are evenly distributed on the outer periphery of the central mounting hole 5. A threaded flange is connected inside the central mounting hole 5, which includes an upper flange 6 and a lower flange 7. The upper flange 6 is detachably connected to the central mounting hole 5, and a positioning pin 9 is provided on the saw blade base 1. The upper flange 6 has a positioning groove 10 corresponding to the positioning pin 9. The lower flange 7 is coaxially connected to the upper flange 6. The inner ring of the upper flange 6 has an internal thread, and the outer ring of the lower flange 7 has an external thread that mates with the internal thread. An anti-loosening boss 11 is connected to the bottom of the upper flange 6, and an anti-loosening groove 12 is correspondingly provided on the top of the lower flange 7. The anti-loosening boss 11 mates with the anti-loosening groove 12. Multiple arrow-shaped protrusions 13 are provided circumferentially on the outer circular surfaces of both the upper flange 6 and the lower flange 7, with the tips of the arrow-shaped protrusions 13 all pointing outwards. A damping rubber ring 14 is provided between the upper flange 6 and the saw blade base 1, and the damping rubber ring 14 is connected in the annular groove on the outer circumference of the upper flange 6. An installation groove 8 is provided on the bottom surface of the lower flange 7.

[0035] Furthermore, the saw blade base 1, upper flange 6, and lower flange 7 are all made of high-strength alloy steel, and the diamond cutter head 3 is made of diamond composite sheet.

[0036] The working process of this utility model is as follows:

[0037] First, the damping rubber ring 14 is installed in the annular groove on the outer circumference of the upper flange 6 to reduce vibration and noise. Then, the upper flange 6 is placed into the mounting center hole 5 in the middle of the saw blade base 1. Next, the positioning pin 9 on the saw blade base 1 is inserted into the corresponding positioning groove 10 on the upper flange 6, achieving initial positioning of the upper flange 6 and the saw blade base 1 to ensure accurate positioning. Then, the lower flange 7 is placed coaxially with the upper flange 6, and then rotated to connect the upper flange 6 and lower flange 7 together via threads. During the screwing process, the anti-loosening boss 11 at the bottom of the upper flange 6 embeds into the corresponding anti-loosening groove 12 at the top of the lower flange 7, preventing loosening during operation. Multiple arrow-shaped protrusions 13 are circumferentially arranged on the outer surfaces of the upper flange 6 and lower flange 7, with their tips pointing outwards, providing mechanical and manual force points for easy installation by operators.

[0038] The saw blade base 1 is then installed onto the equipment. An installation groove 8 is provided on the bottom surface of the lower flange 7 to further fix the saw blade base 1. The equipment then drives the saw blade base 1 to rotate through the installation center hole 5. The outer peripheral edge of the saw blade base 1 has a continuous convex structure, which is fitted and connected with the inner peripheral edge of the diamond cutter head 3, thus driving the diamond cutter head 3 to rotate together. The diamond cutter head 3 is made of diamond composite sheet, which has extremely high hardness and wear resistance. During the rotation, it performs cutting operations on the workpiece. Multiple parallelogram-shaped reinforcing blocks 4 are provided on the upper and lower surfaces of the diamond cutter head 3 and are inclined radially to the saw blade base 1. During cutting, they can enhance the structural strength of the diamond cutter head 3, disperse the stress generated during the cutting process, reduce the damage to the diamond cutter head 3 due to uneven force, and improve the service life of the saw blade. At the same time, the damping rubber ring 14 can maintain vibration reduction and noise reduction during operation. The saw blade base 1 is provided with multiple through holes 2, which are evenly distributed on the outer periphery of the mounting center hole 5. This allows the powder and debris generated during the cutting process to be quickly discharged through the through holes 2, preventing debris accumulation.

[0039] When it is necessary to disassemble the saw blade base 1, rotate the lower flange 7 in the opposite direction to separate the lower flange 7 from the upper flange 6, thereby quickly completing the disassembly of the saw blade base 1 and greatly shortening the disassembly and assembly time.
