Description

Technical Field

[0001] This invention relates to the technical field of saw blade substrate production, and in particular to a method for reducing saw blade substrate vibration and noise. Background Technology

[0002] The structure of the saw blade substrate produced in a certain workshop is as follows: Figures 1-2 As shown, the saw blade base includes a circular saw blade body 1. A central hole 2 is provided in the center of the saw blade body 1. Multiple tooth seats 3 are uniformly fixed on the outer edge of the saw blade body 1 in a circumferential direction. Each tooth seat 3 is integrally formed with the saw blade body 1. Six noise-absorbing grooves 4 are also provided on the outer edge of the saw blade body 1 in a circumferential direction. One end of each noise-absorbing groove 4 has a through hole 5 communicating with it, and the other end passes through the outer edge of the saw blade body 1. The function of the noise-absorbing grooves 4 is to prevent the saw blade base from generating excessive noise when it rotates around its own axis.

[0003] However, although the noise of this saw blade base with the noise reduction groove 4 is relatively small when rotating, it still generates a lot of noise when the saw blade base rotates at high speed around its own axis, and the saw blade base will also wobble, that is, jump from side to side. Excessive jumping will undoubtedly shorten the service life of the saw blade base itself.

[0004] Therefore, there is an urgent need for a method to reduce saw blade body runout and noise. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for reducing saw blade body runout and noise. This objective is achieved through the following technical solution: a method for reducing saw blade body runout and noise, the method comprising the following steps:

[0006] S1. Produce a viscous damping material;

[0007] S2. Inject the viscous damping material into the glue cartridge of the dispensing machine;

[0008] S3. Take out a saw blade base and place the saw blade body of the saw blade base flat on the table of the dispensing machine.

[0009] S4. Insert a plug at the outer port of each silencing groove in the saw blade base;

[0010] S5. Injecting viscous damping material into the first silencing groove of the saw blade body: Operate the dispensing machine so that the dispensing head of the dispensing machine is aligned with the through hole connected to the first silencing groove, and then turn on the dispensing machine so that the dispensing head injects the viscous damping material in the glue tube into the through hole; then move the dispensing head along the length of the silencing groove, thereby realizing the injection of viscous damping material into the first silencing groove of the saw blade body.

[0011] S6. Repeat step S5 multiple times to inject viscous damping material into each of the other sound-absorbing grooves in the saw blade body; after waiting for a period of time, remove the plug.

[0012] S7. Remove the saw blade substrate from the dispensing machine, and then place the saw blade substrate filled with damping material into the oven. The oven will bake the sticky damping material in the silencing groove. After baking for 5 to 8 minutes, the sticky damping material will become a damping material that is firmly attached to the silencing groove, thus obtaining the first saw blade substrate filled with damping material.

[0013] S8. Repeat steps S3 to S7 multiple times to obtain multiple saw blade substrates filled with damping material.

[0014] In step S1, the method for producing a viscous damping material specifically includes the following steps:

[0015] S11. Add a certain amount of damping material to the mixing tank of the mixer, and then add a certain amount of adhesive to the mixing tank of the mixer; turn on the heater outside the mixing tank, and the heater heats the damping material and adhesive in the mixing tank to increase the fluidity of the adhesive; turn on the mixer, and the mixing blades of the mixer mix the damping material and adhesive in the mixing tank. After mixing for a period of time, a semi-finished viscous damping material can be obtained.

[0016] S12. Pour the semi-finished viscous damping material from the mixing tank into a container, and then place the container containing the semi-finished viscous damping material into a freezer. Cool the semi-finished viscous damping material in the freezer. After cooling for 23 to 24 hours, the finished viscous damping material can be produced.

[0017] The saw blade base in step S3 includes a saw blade body. A central hole is provided in the center of the saw blade body. Multiple noise reduction grooves are also provided on the outer edge of the saw blade body and around its circumference. One end of the noise reduction groove is provided with a through hole, and the other end penetrates through the outer edge of the saw blade body.

[0018] Multiple noise-reducing grooves are also provided on the outer edge of the saw blade body and around its circumference. Each noise-reducing groove has a through hole at one end and the other end penetrates through the outer edge of the saw blade body.

[0019] Six noise-reducing grooves are evenly distributed on the outer edge of the saw blade body.

[0020] In step S7, the top surface of the damping material is flush with the top surface of the saw blade body, and the bottom surface of the damping material is flush with the bottom surface of the saw blade body.

[0021] The present invention has the following advantages:

[0022] The saw blade substrate produced by this method, filled with damping material, exhibits significantly less vibration and generates less noise compared to existing saw blade substrates without damping material, thereby effectively extending the service life of the saw blade substrate.

[0030] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0031] like Figures 3-4 As shown, a method for reducing saw blade body runout and noise includes the following steps:

[0032] S1. Prepare a viscous damping material, specifically including the following steps:

[0033] S11. Add a certain amount of damping material to the mixing tank of the mixer, and then add a certain amount of adhesive to the mixing tank of the mixer; turn on the heater outside the mixing tank, and the heater heats the damping material and adhesive in the mixing tank to increase the fluidity of the adhesive; turn on the mixer, and the mixing blades of the mixer mix the damping material and adhesive in the mixing tank. After mixing for a period of time, a semi-finished viscous damping material can be obtained.

[0034] S12. Pour the semi-finished viscous damping material in the mixing tank into a container, and then put the container containing the semi-finished viscous damping material into a freezer. Cool the semi-finished viscous damping material in the freezer. After cooling for 23 to 24 hours, the finished viscous damping material can be produced.

[0035] S2. Inject the viscous damping material into the glue cartridge of the dispensing machine;

[0036] S3. Take out a saw blade base and place the saw blade body 1 of the saw blade base flat on the table of the dispensing machine.

[0037] S4. A plug 7 is inserted at the outer port of each noise-reducing groove 4 in the saw blade base;

[0038] S5. Injecting viscous damping material into the first silencing groove 4 of the saw blade base: Operate the dispensing machine so that the dispensing head of the dispensing machine is aligned with the through hole 5 connected to the first silencing groove 4, and then turn on the dispensing machine so that the dispensing head injects the viscous damping material in the glue tube into the through hole 5; then move the dispensing head along the length of the silencing groove 4, thereby realizing the injection of viscous damping material into the first silencing groove 4 of the saw blade base.

[0039] S6. Repeat step S5 multiple times to inject viscous damping material into the other sound-absorbing grooves 4 of the saw blade body; after waiting for a period of time, remove the plug 7.

[0040] S7. Remove the saw blade substrate from the dispensing machine and then place the saw blade substrate filled with damping material into an oven. The oven bakes the sticky damping material in the silencing groove 4. After baking for 5 to 8 minutes, the sticky damping material becomes a damping material firmly attached to the silencing groove 4, thus obtaining the first saw blade substrate filled with damping material. The top surface of the damping material 6 is flush with the top surface of the saw blade body 1, and the bottom surface of the damping material 6 is flush with the bottom surface of the saw blade body 1.

[0041] S8. Repeat steps S3 to S7 multiple times to obtain multiple saw blade substrates filled with damping material.

[0042] The saw blade base in step S3 includes a saw blade body 1. A central hole 2 is formed in the center of the saw blade body 1. Multiple noise-absorbing grooves 4 are formed on the outer edge of the saw blade body 1 in a circumferential direction. One end of each noise-absorbing groove 4 has a through hole 5, and the other end penetrates the outer edge of the saw blade body 1. Six noise-absorbing grooves 4 are evenly distributed on the outer edge of the saw blade body 1.

[0043] In step S7, the saw blade substrate filled with damping material is fixedly installed on the rotating shaft. The rotating shaft is driven to rotate by the power motor, and the rotating shaft drives the saw blade substrate to rotate synchronously.

[0044] When saw blade substrates filled with damping material are operated at speeds of 2000 rpm, 2500 rpm, 2800 rpm, 3000 rpm, 3200 rpm, 3500 rpm, 3800 rpm, 4000 rpm, 4200 rpm, 4500 rpm, 4800 rpm, and 5000 rpm, the vibration and noise generated by the saw blade substrates are measured. The table below shows a comparison between saw blade substrates filled with damping material and those without.

[0045]

[0046] As can be seen from the table, the saw blade substrate filled with damping material produced by this method has significantly less vibration and generates less noise compared to the existing technology saw blade substrate without damping material, thus effectively extending the service life of the saw blade substrate.
