Description

Technical Field

[0001] This application relates to the field of grinding tool technology, and more specifically, to a grinding wheel substrate and a grinding wheel. Background Technology

[0002] Abrasive wheels play a vital role in industrial production. Widely used in the processing of industrial products, they can grind and polish metal products as well as non-metallic materials such as stone and wood, making them an essential consumable in industrial processing. An abrasive wheel is made by cutting cloth-based abrasive cloth into small pieces (blocks) of specific shapes according to different uses and performance requirements. These pieces are then bonded to a substrate (fixed cover) in a circular matrix pattern using a chemical adhesive. The adhesive is then hardened through heating, ultraviolet light, or other methods to give the wheel a specific rotational strength.

[0003] Existing abrasive wheel substrates are made of metal or fiberglass mesh. Metal substrates have high hardness, and upon impact during grinding, there is no cushioning, causing equipment vibration to be transmitted to the operator's hands, resulting in a heavy workload. While fiberglass mesh substrates have better toughness and excellent vibration damping, their strength is relatively poor. Under heavy-pressure grinding, the substrate is prone to axial deformation, affecting grinding quality. Summary of the Invention

[0004] To at least partially overcome the problems existing in related technologies, the purpose of this application is to provide a grinding wheel matrix and a grinding wheel that can solve the problems of poor vibration damping capacity of existing metal matrices leading to heavy operator workload and the problems of poor strength and easy deformation of existing glass fiber mesh matrices affecting grinding quality. The various technical effects of the preferred technical solutions provided in this application are detailed below.

[0005] This application provides an abrasive wheel substrate, comprising: a metal disc and a fiberglass mesh, wherein the metal disc is provided with mounting holes for connecting a grinding device, the first end face of the fiberglass mesh is pressed and attached to the metal disc, and the second end face of the fiberglass mesh is used to adhere abrasive cloth.

[0006] Optionally, the metal disk includes:

[0007] A base plate, wherein the mounting holes are provided on the base plate;

[0008] A fixing cylinder, wherein the fiberglass mesh is sleeved on the fixing cylinder and pressed and attached to the base plate.

[0009] Optionally, the fixed cylinder has a bent portion at one end away from the base plate, and the bent portion abuts against the second end face of the glass fiber mesh cloth away from the base plate.

[0010] Optionally, the base plate is cymbal-shaped.

[0011] Optionally, the metal disc has spikes on its surface near the fiberglass mesh.

[0012] Optionally, at least two spikes are provided and are evenly distributed along the circumference of the metal disk.

[0013] This application provides an abrasive wheel, including the abrasive wheel base as described in any of the above claims.

[0014] The technical solution provided in this application may include the following beneficial effects:

[0015] This application provides an abrasive wheel substrate, comprising: a metal disc and a fiberglass mesh. The metal disc has mounting holes for connecting grinding equipment. The first end face of the fiberglass mesh is pressed and attached to the metal disc, and the second end face of the fiberglass mesh is used to adhere abrasive cloth. In use, the power shaft of a rotating device such as an angle grinder is inserted into the mounting holes on the metal disc and fixed, thereby mounting the abrasive wheel on the rotating device. Grinding operations can then be performed by starting the rotating device. During operation, the metal disc provides good strength and is not easily deformed, thus affecting the grinding quality. The fiberglass mesh substrate acts as a shock absorber between the metal disc and the abrasive cloth, reducing vibrations transmitted to the metal disc during grinding and reducing the operator's workload.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0026] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations represented in the embodiments below are not limited to those necessary for the solution of the invention described in the claims.

[0027] refer to Figure 1-5 This specific embodiment provides an abrasive wheel substrate, including: a metal disc 1 and a fiberglass mesh substrate 2. The metal disc 1 is formed by stamping a metal part, and mounting holes 3 are formed on the metal part. A fiberglass mesh workpiece is attached to the metal part, and a stamping device is used to press and attach the fiberglass mesh workpiece and the metal part together. The metal part is stamped to form the metal disc 1, and mounting holes 3 are formed on the metal disc 1. The fiberglass mesh workpiece is stamped to form the fiberglass mesh substrate 2. At this time, the first end face of the fiberglass mesh substrate 2 is pressed and attached to the metal disc 1, and the second end face of the fiberglass mesh substrate 2 is used to adhere abrasive cloth.

[0028] When making the abrasive wheel, abrasive cloth is adhered to the second end face of the fiberglass mesh substrate 2. In use, the power shaft of a rotating device such as an angle grinder is inserted into the mounting hole 3 on the metal disc 1 and fixed, thus mounting the abrasive wheel on the angle grinder. The angle grinder can then be started for grinding operations. During operation, the metal disc 1 provides good strength and is not easily deformed, thus affecting the grinding quality. The fiberglass mesh substrate 2 acts as a shock absorber between the metal disc 1 and the abrasive cloth, reducing vibrations transmitted to the metal disc 1 during grinding and reducing the operator's workload.

[0029] As an optional implementation, the metal disk 1 includes a base disk 11 and a fixing cylinder 12. The metal part includes a circular plate and a cylinder, with a mounting hole 3 on the circular plate communicating with the cylinder. After the fiberglass mesh workpiece is sleeved on the fixing cylinder 12, it is attached to the circular plate, and a stamping device is used to press and attach the fiberglass mesh workpiece and the metal part together. At this time, the circular plate forms the base disk 11, and the cylinder is the fixing cylinder 12. The fiberglass mesh workpiece forms the fiberglass mesh substrate 2 and is pressed and attached to the base disk 11.

[0030] In some embodiments, after stamping, the end of the fixing cylinder 12 away from the base plate 11 forms a bend 13, at which point the bend 13 abuts against the second end face of the fiberglass mesh substrate 2. This makes the connection between the fiberglass mesh substrate 2 and the base plate 11 more stable, preventing the fiberglass mesh substrate 2 from falling off.

[0031] As an optional implementation, the base plate 11 is cymbal-shaped. That is, the base plate 11 includes a first plane, a first inclined plane, and a second plane. After being stamped using a stamping device, the fiberglass mesh fabric workpiece forms a cymbal-shaped fiberglass mesh fabric substrate 2. At this time, the cymbal-shaped fiberglass mesh fabric substrate 2 includes a third plane, a second inclined plane, and a fourth plane. The first plane of the base plate 11 is attached to the third plane of the fiberglass mesh fabric substrate 2. The first inclined plane of the base plate 11 is attached to the second inclined plane of the fiberglass mesh fabric substrate 2. The second plane of the base plate 11 is attached to the fourth plane of the fiberglass mesh fabric substrate 2. Compared to a straight-plane attachment, the structure is more stable.

[0032] As an optional implementation, the surface of the metal disc 1 near the fiberglass mesh substrate 2 is provided with spikes 4. That is, the metal part is provided with spikes 4, and after being stamped using a stamping device, the spikes 4 on the metal disc 1 pierce the first end face of the fiberglass mesh substrate 2. This prevents rotation between the fiberglass mesh substrate 2 and the metal disc 1 during the grinding process.

[0033] In some embodiments, at least two spikes 4 are provided and evenly distributed along the circumference of the metal disk 1. Six spikes 4 may be provided. This multiple-position fixing results in a more robust connection.

[0034] This application also provides an abrasive wheel, including the abrasive wheel substrate described in the above embodiments. The derivation process of this beneficial effect is largely similar to the derivation process of the beneficial effect brought by the abrasive wheel substrate, so it will not be repeated here.
