Description

Technical Field

[0001] The utility model belongs to the technical field of cutting tools, and in particular relates to a lightweight energy-saving saw blade. Background Art

[0002] Saw blade is a general term for thin circular cutting tools used to cut solid materials. Saw blades are usually composed of a saw blade base and a cutter head arranged on the outer periphery of the saw blade. The base of existing saw blades is mostly a complete disk surface, which is not conducive to chip removal and heat dissipation. In addition, the saw blade itself has a certain weight, which has a certain limit on the speed of the saw blade. It requires more external energy (usually electrical energy) to work continuously. Utility Model Content

[0003] The utility model aims to provide a light energy-saving saw blade with small dead weight and good heat dissipation.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] In the first aspect, the utility model provides a lightweight energy-saving saw blade, including a disk and a cutter head, wherein the cutter head is installed or formed on the outer periphery of the disk, the cutter head includes teeth, the teeth are V-shaped dovetail type, and blades are provided on the sides of the teeth; the disk includes a base, the circumference center of the disk is on the base, a center hole is opened in the center of the base, and hollow structures are symmetrically opened on the disk around the center hole.

[0006] Furthermore, the V-shaped dovetail type has a V-shaped groove in the middle of the dovetail tooth.

[0007] In an embodiment of the present invention, the hollow structure is formed by cutting using a laser cutting technique.

[0008] It should be noted that, while ensuring that the base maintains high strength, is not easy to break and operates stably when the saw blade is running, a hollow design of proportional combination holes is performed on the surface of the base, and laser cutting technology is used to cut and hollow out the complete base disk surface.

[0009] Furthermore, the hollow structure is a Y-shaped structure formed by opening a combination of holes in the fan shape.

[0010] It should be noted that, combined with the above, the Y-shaped structure can not only ensure the integrity of the connection of the saw blade base, but also reduce the weight of the saw blade itself. During operation, it can reduce the resistance and loss caused by the saw blade itself, extend the service life of the saw blade, and improve cutting efficiency; the hollow part can be used as a channel for chip removal, which is conducive to chip removal and heat dissipation, and has a certain energy-saving effect; the dovetail tooth seat design (that is, the teeth included in the aforementioned cutter head) can improve the impact resistance of the saw blade.

[0011] In one embodiment of the present invention, concave chip removal channels are formed between different groups of cutter heads.

[0012] It should be noted that the chip removal channel combined with the aforementioned hollow portion further enhances the chip removal capability of the saw blade of the present application.

[0013] In an embodiment of the present invention, there are four groups of hollow structures.

[0014] In one embodiment of the present invention, the combined hole includes hole one, hole two, and hole three, and the opening positions of hole one, hole two, and hole three are in equal proportion.

[0015] It should be noted that four groups of identical hollow patterns are cut on the disk surface according to a certain ratio. Multiple groups of hollow structures further reduce the weight of the saw blade, and the symmetrical design improves the balance of the saw blade, further reduces the saw blade's own resistance and loss, improves cutting efficiency, better dissipates heat, and extends the service life of the saw blade.

[0016] In one embodiment of the present invention, the Y-shaped structure includes two symmetrical short sides and one long side, the two short sides and the base form the first hole, and the short side, the long side and the base form the second hole or the third hole.

[0017] In an embodiment of the present invention, compared with the second hole and the third hole, the first hole is closer to the central hole.

[0018] In an embodiment of the present invention, the central hole comprises a circular hole, and the circular hole symmetrically connects two rectangular holes.

[0019] In one embodiment of the present invention, the blades of different groups are evenly spaced and distributed on the periphery of the disk.

[0020] It should be noted that the uniform distribution of the cutter heads improves the balance of the saw blade.

[0021] The beneficial effects of the utility model are:

[0022] First, the saw blade of the present application has high strength, low deadweight and is lightweight. When ensuring that the saw blade maintains high strength, is not easy to break and operates stably when the saw blade is running, the surface of the base is hollowed out with proportional combination holes, and laser cutting technology is used to cut hollows on the complete base disk. The hollow structure is a Y-shaped structure formed by opening combination holes in the fan shape. The base cooperates with the Y-shaped structure to ensure the integrity of the connection of the saw blade base and reduce the weight of the saw blade itself. When working, it can reduce the resistance and loss caused by the saw blade itself, extend the service life of the saw blade, and improve cutting efficiency; the V-shaped dovetail tooth seat design (that is, the teeth included in the aforementioned cutter head) can improve the impact resistance of the saw blade. Furthermore, the hollow structure is set to multiple groups, and multiple groups of hollow structures can further reduce the dead weight of the saw blade, and the symmetrical design improves the balance of the saw blade.

[0023] Second, the saw blade of the present application has good heat dissipation. The hollowed-out part of the hollowed-out structure can be used as a channel for chip removal, which is conducive to chip removal while ensuring the stable operation of the saw blade, and can better dissipate the heat generated by the saw blade when it is working. Under the same working environment, compared with saw blades without hollowed-out structures, the saw blade of the present application has a certain energy-saving effect; concave chip removal channels are formed between the blade heads of different groups. The chip removal channel combined with the aforementioned hollowed-out part further enhances the chip removal capacity of the saw blade of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] Reference Figure 1 A lightweight energy-saving saw blade includes a cutter head 14, and the cutter head includes teeth 1. The teeth 1 are V-shaped dovetail teeth, and the teeth 1 are dovetail teeth with a V-shaped groove in the middle. The teeth 1 of the present application are based on the modification of dovetail teeth. The mechanism of dovetail teeth is well known and will not be described in detail. A blade 2 is provided on the side of the tooth 1. The blade 2 can be symmetrically arranged on one side or both sides of the side of the tooth 1. It should be noted that the design of the V-shaped dovetail tooth seat (i.e., tooth 1) can alleviate the impact force on the cutter head 14, improve the impact resistance of the saw blade, and extend the service life of the saw blade.

[0029] A plurality of groups of cutter heads 14 are evenly spaced and installed or formed on the outer periphery of the disk surface 13 , and concave chip removal channels 3 are formed between the groups of cutter heads 14 .

[0030] The disk surface 13 includes a base body 4 , the circumference center of the disk surface 13 is on the base body 4 , a center hole 5 is opened in the center of the base body 4 , and the center hole 5 includes a circular hole 6 , and two rectangular holes 7 are symmetrically connected on both sides of the circular hole 6 .

[0031] A hollow structure is symmetrically opened on the disk surface 13 around the central hole 5. The hollow structure is formed by laser cutting technology. There are four groups of hollow structures. Each group of hollow structures is a Y-shaped structure formed by opening a combination hole in a fan shape. The combination hole is the hollow part of the hollow structure, and the Y-shaped structure is the non-hollow entity of the hollow structure.

[0032] It should be noted that, while ensuring that the base 4 maintains high strength, is not easy to break and operates stably when the saw blade is running, the surface of the base 4 is hollowed out with proportional combination holes, and laser cutting technology is used to cut hollow holes on the complete base disk surface. This can not only ensure the integrity of the connection of the saw blade base 4, but also reduce the weight of the saw blade itself, reduce the resistance and loss caused by the saw blade itself during operation, extend the service life of the saw blade, and improve cutting efficiency.

[0033] Further, the combined hole includes hole 1 8, hole 2 9, and hole 3 10, and the opening positions of hole 1 8, hole 2 9, and hole 3 10 are in equal proportion. The Y-shaped structure includes two symmetrical short sides 11 and one long side 12, and the two short sides 11 and the base 4 form hole 1 8, and any short side 11 and the long side 12 and the base 4 form hole 2 9 or hole 3 10. Compared with hole 2 9 and hole 3 10, hole 1 8 is closer to the center hole 5.

[0034] It should be noted that the hollowed-out part of the hollowed-out structure can also be used as a channel for chip removal, and the saw blade of the present application is more conducive to chip removal in combination with the chip removal channel 3. Under the same working environment, the hollowed-out part can also dissipate heat better, and has a certain energy-saving effect.

[0035] The working principle of the saw blade is relatively well known. The present application is an improvement on the saw blade structure. One working method is now provided. The saw blade of the present application is mounted on the saw blade shaft of an electric saw. After the electric saw is started, the saw blade rotates, and the cutter head 14 cuts the target object. The debris can be discharged through the hollow structure and the chip removal channel 3.

[0036] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
