Description

Technical Field

[0001] The utility model relates to the technical field of cutting products, in particular to a diamond cutting and grinding disc with the functions of silencing and reducing vibration. Background Art

[0002] Diamond saw blades and diamond grinding discs are commonly used consumables in the field of cutting. They are usually operated with the help of cutting and grinding equipment, such as angle grinders or portable saws, etc. The diamond saw blades and diamond grinding discs are fastened to the rotating shaft of the cutting and grinding equipment through nuts or bolts. However, ordinary diamond saw blades and diamond grinding discs make loud noises and vibrate greatly when working. In order to reduce noise and vibration, it is usually adopted to open silencer holes or guide grooves to disrupt the airflow or facilitate chip removal and reduce friction, so as to achieve the purpose of reducing noise and vibration.

[0003] Although the above methods can achieve the effect of noise reduction and vibration reduction, there will still be inevitable vibration and noise, which will be transmitted to the user through the cutting and grinding equipment, causing noise and vibration to the user, which may affect the user's work at the least and may damage the equipment at the worst. Therefore, there is an urgent need for a diamond cutting and grinding disc with noise reduction and vibration reduction function to reduce noise and vibration between the cutting and grinding disc and the cutting and grinding equipment. Utility Model Content

[0004] The utility model aims to provide a diamond cutting and grinding disc with the function of silencing and reducing vibration, so as to solve the problem that the noise and vibration of the cutting and grinding disc are transmitted between cutting and grinding equipment.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A diamond cutting and grinding disc with noise reduction and vibration reduction functions, comprising:

[0007] A cutting and grinding substrate, wherein the cutting and grinding substrate is a diamond saw blade or a diamond grinding disc;

[0008] A sound-absorbing and vibration-damping component, the sound-absorbing and vibration-damping component includes a metal pressure cover and a vibration-damping and noise-damping plate. The two metal pressure covers press the outer edges of the vibration-damping and noise-damping plates onto the inner edges of the cutting and grinding base mounting holes. The vibration-damping and noise-damping plates are elastically connected to the cutting and grinding base.

[0009] A further technical solution is that the vibration-damping and noise-reducing sheet is made of EPDM rubber or NBR rubber.

[0010] A further technical solution is that a groove matching the mounting hole of the cutting and grinding base is arranged on the outer periphery of the vibration-damping and sound-absorbing plate.

[0011] A further technical solution is that the vibration-damping and noise-reducing plate is an annular structure.

[0012] A further technical solution is that the vibration-damping and noise-reducing plate is divided into an upper ring plate and a lower ring plate.

[0013] A further technical solution is that the metal gland is provided with an annular protrusion which blocks the outer edge of the vibration-damping and sound-absorbing plate.

[0014] A further technical solution is that the metal glands are connected by bolts or compressed by external cutting and grinding equipment and nuts on the rotating shaft.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0016] The utility model provides a diamond cutting and grinding disc with noise reduction and vibration reduction functions. The cutting and grinding disc is not only suitable for diamond saw blades or diamond grinding discs, but also can be used for other close or similar cutting and grinding consumables. The use of the vibration reduction and noise reduction disc can greatly reduce the noise and vibration on the cutting and grinding disc that are transmitted to the cutting and grinding equipment and even the user, thereby reducing the impact of the cutting and grinding disc on the cutting and grinding equipment or the user.

There are usually two ways of such pressing. The first is to connect the two metal pressure covers 3 by bolts to press the vibration-damping and sound-absorbing plate 4; the second is to press the two metal pressure covers 3 onto the rotating shaft of the external cutting and grinding equipment by nuts to press the vibration-damping and sound-absorbing plate 4.
