Description

Technical Field

[0001] The present application relates to the technical field of saw blades, and in particular to an energy-saving fast-cutting saw blade. Background Art

[0002] Saw blades are a general term for thin circular tools used to cut solid materials. Saw blades can be divided into: diamond saw blades for stone cutting, high-speed steel saw blades for metal cutting, and carbide saw blades for cutting solid wood, furniture, artificial boards, aluminum alloys, aluminum profiles, radiators, plastics, plastic steel, etc.

[0003] When saw blades currently on the market cut objects, the cutting teeth of the saw blades collide with the objects to cut off the objects. After long-term use, the cutting teeth of the saw blades become blunt, which will cause the friction resistance of the saw blades to increase when cutting objects, affecting the cutting life of the saw teeth and being detrimental to the normal use of the saw blades. Summary of the invention

[0004] In view of the shortcomings of the prior art, the embodiment of the present application provides an energy-saving fast-cutting saw blade to solve the problems existing in the related technology. The technical solution is as follows:

[0005] An embodiment of the present application provides an energy-saving quick-cut saw blade, comprising: a main body; a mounting hole is arranged at the axis of the main body; a plurality of silencer holes are radially arranged on the main body; a plurality of cutting components and a plurality of radial grooves are circumferentially arranged on the outer side of the main body; the cutting component comprises a first cutting part and a second cutting part.

[0006] In one embodiment, the first cutting portion includes: a first cutting tooth and a second cutting tooth; the first cutting tooth and the second cutting tooth are both arranged on the outside of the main body; the first cutting tooth is located on one side of the second cutting tooth, and the second cutting portion is located on the other side of the second cutting tooth.

[0007] In one embodiment, the cutting width of the first cutting tooth is greater than or equal to the cutting width of the second cutting tooth.

[0008] In one embodiment, the second cutting portion includes: a third cutting tooth and a fourth cutting tooth; the third cutting tooth and the fourth cutting tooth are both arranged on the outside of the main body; the second cutting tooth is located on one side of the third cutting tooth, and the fourth cutting tooth is located on the other side of the third cutting tooth.

[0009] In one embodiment, the cutting width of the third cutting tooth is greater than or equal to the cutting width of the fourth cutting tooth.

[0010] In one embodiment, the cutting width difference between the first cutting tooth and the second cutting tooth is M1, wherein 0.02 mm≤M1≤0.1 mm.

[0011] In one embodiment, the cutting width difference between the third cutting tooth and the fourth cutting tooth is M2, wherein 0.02 mm≤M2≤0.1 mm.

[0012] In one embodiment, the number of the radial grooves is an odd number; the odd number of radial grooves are equidistantly arranged on the outer side of the main body.

[0013] In one embodiment, the surface of the main body is polished with sandpaper.

[0014] The advantages or beneficial effects of the above technical solution include at least:

[0015] The cutting assembly of the present application includes a first cutting part and a second cutting part. The two cutting parts can form a stepped combination of saw teeth. When the saw blade cuts an object, the cutting method of the stepped combination of saw teeth can reduce the friction resistance during cutting. At the same time, through the reciprocating cutting of multiple groups of cutting assemblies, the cutting sharpness can be significantly increased, thereby extending the cutting life of the saw teeth and facilitating the normal use of the saw blade.

[0023] In the following, only some exemplary embodiments are briefly described to make the purpose, features and advantages of the utility model more obvious and understandable. As those skilled in the art will appreciate, the described embodiments can be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment 1

[0026] like Figures 1 to 3 As shown, this embodiment provides a first implementation of an energy-saving quick-cut saw blade, including: a main body 1; a mounting hole 2 is arranged at the axis of the main body 1; a plurality of silencer holes 3 are radially arranged on the main body 1; a plurality of cutting components 4 and a plurality of radial grooves 5 are circumferentially arranged on the outer side of the main body 1; the cutting component 4 includes a first cutting part and a second cutting part.

[0027] In this embodiment, the cutting assembly 4 includes a first cutting part and a second cutting part, each of which has two cutting teeth. The first cutting part and the second cutting part form a stepped combination of four teeth. When the saw blade is used for cutting, the first teeth can reduce the friction resistance of the second teeth and play a trimming and grinding role on the second teeth, thereby improving the cutting sharpness of the saw blade and the smoothness of the cut surface, so as to extend the cutting life of the saw teeth and facilitate the normal use of the saw blade;

[0028] The saw blade is connected to an external device through a mounting hole at the axis of the main body 1; a plurality of silencer holes 3 are radially arranged on the main body 1, which can play a role in silencing and reducing noise when the saw blade cuts objects; radial grooves 5 are arranged between the cutting components 4, which can make the saw blade cut more stably.

[0029] Further, the first cutting part includes: a first cutting tooth 61 and a second cutting tooth 62; the first cutting tooth 61 and the second cutting tooth 62 are both arranged on the outside of the main body 1; the first cutting tooth 61 is located on one side of the second cutting tooth 62, and the second cutting part is located on the other side of the second cutting tooth 62. The incision width of the first cutting tooth 61 is larger than the incision width of the second cutting tooth 62. The second cutting part includes: a third cutting tooth 63 and a fourth cutting tooth 64; the third cutting tooth 63 and the fourth cutting tooth 64 are both arranged on the outside of the main body 1; the second cutting tooth 62 is located on one side of the third cutting tooth 63, and the fourth cutting tooth 64 is located on the other side of the third cutting tooth 63. The incision width of the third cutting tooth 63 is larger than the incision width of the fourth cutting tooth 64. The incision width difference between the first cutting tooth 61 and the second cutting tooth 62 is M1; wherein 0.02mm≤M1≤0.1mm. The difference in cutting width between the third cutting tooth 63 and the fourth cutting tooth 64 is M2, wherein 0.02 mm≤M2≤0.1 mm.

[0030] In this embodiment, the first cutting tooth 61, the second cutting tooth 62, the third cutting tooth 63 and the fourth cutting tooth 64 are sequentially arranged on the outer edge of the main body 1 from left to right. When each cutting tooth is ground, the cutting width of the first cutting tooth 61 is 0.02mm-0.1mm larger than the cutting width of the second cutting tooth 62, and the cutting width of the third cutting tooth 63 is 0.02mm-0.1mm larger than the cutting width of the fourth cutting tooth 64, thereby forming a stepped combination (see Figure 3 ); Four teeth in a group reciprocating cycle cutting can reduce the friction resistance of the saw blade during cutting, increase the cutting sharpness, thereby extending the service life of the overall saw teeth and reducing energy loss;

[0031] In addition, the structure in which the left cutting teeth (first cutting teeth 61 and third cutting teeth 63) are slightly higher than the right cutting teeth (second cutting teeth 62 and fourth cutting teeth 64) enables the right cutting teeth to trim and polish the cut surface cut by the left cutting teeth, thereby increasing the smoothness of the cut surface.

[0032] Furthermore, the number of the radial grooves 5 is an odd number; the odd number of radial grooves 5 are equidistantly arranged on the outer side of the main body 1 .

[0033] Research shows that after radial grooves are formed on the saw blade, the unstable rotation speed range of the saw blade becomes narrower, and an odd number of grooves is better than an even number of grooves. In this embodiment, the outer side of the main body 1 has an odd number of radial grooves 5, and the spacing between the radial grooves 5 is equal, so that the saw blade is more stable when working and cutting.

[0034] Furthermore, the surface of the main body 1 is polished with sandpaper.

[0035] In this embodiment, the main body 1 is made of steel material, and the surface of the main body 1 is polished with sandpaper to make its surface smooth.

[0036] Embodiment 2

[0037] like Figure 4 As shown, this embodiment provides a second implementation of an energy-saving fast-cutting saw blade, wherein the cutting width of the first cutting tooth 61 is equal to the cutting width of the second cutting tooth 62. The cutting width of the third cutting tooth 63 is equal to the cutting width of the fourth cutting tooth 64.

[0038] In this embodiment, the incision width of the first cutting tooth 61 is equal to the incision width of the second cutting tooth 62, the incision width of the third cutting tooth 63 is equal to the incision width of the fourth cutting tooth 64, and the incision width of the first cutting tooth 61 is 0.02mm-0.1mm larger than the incision width of the third cutting tooth 62, and the incision width of the second cutting tooth 63 is 0.02mm-0.1mm larger than the incision width of the fourth cutting tooth 64, thereby forming a stepped combination (see Figure 4 ), this structure can achieve the same cutting function and cutting effect as the first embodiment.
