Description

Technical Field

[0001] This utility model relates to the field of electric cutting machines, and specifically to a cutting blade for a cutting machine. Background Technology

[0002] Electric cutting machines include an output shaft and an operating head. The operating head can hold the cutting blade. Currently, the most commonly used cutting blades are flat. A flat saw blade is a blade whose two sides facing each other are flat. The surface of a flat cutting blade is a smooth rough surface. Therefore, its cutting speed is slow and the grinding effect is poor. When cutting or grinding, iron filings cannot be removed and can easily enter the machine housing from the operating head.

[0003] In addition, the cutting disc is clamped at the center hole of the operating head, and the motor drives the spindle to rotate the cutting disc. The clamping point is easily scratched and damaged due to the rapid rotation during operation. The inability to distribute the drive and clamping pressure reduces the service life, increases the cost of use, greatly affects work efficiency, and causes great trouble for users. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of existing technologies and provide a cutting method that is more conducive to debris removal and has a longer service life. This utility model is achieved through the following technical solution:

[0005] A cutting disc includes a circular body, the body including a first surface, a second surface, and a mounting hole penetrating the first and second surfaces, the mounting hole being located at the center of the cutting disc. The cutting disc includes a reinforcing ring concentric with the mounting hole, the reinforcing ring partially covering the first and second surfaces of the body, the reinforcing ring being hollow near the center of the cutting disc to expose the mounting hole, the density of the reinforcing ring being less than the density of the body; the body also includes protrusions arranged radially around the mounting hole, the protrusions being formed on at least one of the first and second surfaces and distributed around the outer periphery of the reinforcing ring.

[0006] Furthermore, the reinforcing ring is fixedly connected to the cutting disc body by glue, buckle, screw or injection molding, forming a permanent bond with the cutting disc. It is hard and tough at working temperature, has a high coefficient of friction, and is used for shock absorption during the cutting process, making the cutting smoother.

[0007] Furthermore, the reinforcing ring is made of resin, and is concentric with the central hole. It is impregnated with a resin material that is rigid at operating temperature, providing a clamping surface for receiving the cutting machine clamping part.

[0008] Furthermore, the reinforcing ring protrudes beyond the first surface by a dimension greater than the thickness of the main body, and greater than 1 / 3 of the thickness of the main body, to facilitate clamping by the cutting machine.

[0009] Furthermore, the two adjacent protrusions form a dust discharge channel, through which debris can be discharged during grinding, preventing debris from seeping into the machine housing from the clamping point and causing malfunctions in the cutting machine.

[0010] Furthermore, the protrusion can be arc-shaped or gradually tapered, which can also achieve the purpose of forming a dust removal channel. In addition, the protrusion can eliminate stress, enhance the strength of the substrate, and reduce swaying during the cutting process.

[0011] Furthermore, the reinforcing ring is circular, and the ratio of the difference between the outer diameter and the inner diameter of the reinforcing ring to the radius of the mounting hole is not less than 1.

[0012] Furthermore, the cutting disc includes raised strips disposed on the first surface, the raised strips being arranged radially around the mounting hole.

[0013] Furthermore, the protrusion is arc-shaped or straight, and the protrusion is constructed as cutting teeth to improve cutting efficiency.

[0014] Furthermore, the convex strips are distributed on the cutting blade at one end away from the reinforcing ring, and are in direct contact with the object being cut, thereby reducing resistance during the cutting process.

[0015] The cutting disc has a reinforcing ring at its center for clamping by the cutting machine, and the reinforcing ring is made of wear-resistant resin, increasing the service life of the cutting disc. Furthermore, the surface of the cutting disc also has protrusions, with two adjacent protrusions forming a channel. During grinding, debris can be discharged through this dust removal channel, preventing debris from seeping into the cutting machine housing from the clamping point and causing malfunctions. This also facilitates debris removal, extends the service life of the cutting machine, and significantly improves work efficiency. Attached Figure Description

[0020] Combination Figures 1 to 2 A cutting disc 100 includes a circular body. The body includes a first surface 101, a second surface 102, and a mounting hole 103 penetrating the first surface 101 and the second surface 102. The mounting hole 103 is located at the center of the cutting disc 100. The cutting disc 100 includes a reinforcing ring 1 concentric with the mounting hole 103. The reinforcing ring 1 partially covers the first surface 101 and the second surface 102 of the body. The reinforcing ring 1 is hollow near the center of the cutting disc 100 to expose the mounting hole 103. The density of the reinforcing ring 1 is less than the density of the body. The body also includes protrusions 2 arranged radially around the mounting hole 103. The protrusions 2 are formed on at least one of the first surface 101 and the second surface 102 and are distributed on the outer periphery of the reinforcing ring 1.

[0021] Preferably, the reinforcing ring 1 is fixedly connected to the main body of the cutting disc 100 by glue, buckle, screw or injection molding, forming a permanent bond with the cutting disc 100. It is hard and tough at working temperature, has a high coefficient of friction, and is used for shock absorption during the cutting process, making the cutting smoother.

[0022] Preferably, the reinforcing ring 1 is made of resin, and the reinforcing ring 1 is concentric with the center hole. It is impregnated with a resin material that is rigid at the working temperature, and provides a clamping surface for receiving the cutting machine clamping part. The reinforcing ring 1 protrudes from the first surface 101 by a dimension greater than the thickness of the body and greater than 1 / 3 of the thickness of the body for clamping by the cutting machine.

[0023] The two adjacent protrusions 2 form a dust removal channel. During grinding, the debris can be discharged through this dust removal channel, preventing debris from seeping into the inside of the cutting machine housing from the clamping point and causing malfunctions. The protrusions 2 can be arc-shaped or gradually tapered, which can also achieve the purpose of forming a dust removal channel. In addition, the protrusions 2 can eliminate stress, enhance the strength of the base material, and reduce swaying during the cutting process.

[0024] Preferably, the reinforcing ring 1 is circular, and the ratio of the difference between the outer diameter and the inner diameter of the reinforcing ring 1 to the radius of the mounting hole 103 is not less than 1.

[0025] The cutting blade 100 includes protrusions 3 disposed on the first surface 101, the protrusions 3 being arranged radially around the mounting hole 103. The protrusions 3 are arc-shaped or straight, and are constructed as cutting teeth to improve cutting efficiency. The protrusions 3 are distributed on the cutting blade 100 at one end away from the reinforcing ring 1, directly contacting the object being cut, reducing resistance during the cutting process.

[0026] The cutting disc 100 has a reinforcing ring 1 at its center for clamping by the cutting machine, and the reinforcing ring 1 is made of wear-resistant resin, thereby increasing the service life of the cutting disc 100. In addition, the surface of the cutting disc 100 is also provided with the protrusions 2, and two adjacent protrusions 2 form a channel. During grinding, the debris can be discharged through the dust discharge channel, preventing the debris from seeping into the inside of the cutting machine housing from the clamping point and causing the cutting machine to malfunction. It is also more convenient to remove debris and improve the service life of the cutting machine, greatly improving work efficiency.
