Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the drawings and the embodiments.

Referring to fig. 1-4, the alloy saw blade for cutting wood comprises a saw blade base 1 (preferably made of iron) with a circular structure, and specifically, the saw blade base 1 further comprises a clamping hole 101 formed in the center thereof and heat dissipation holes 102 uniformly distributed on the surface of the saw blade base 1. The saw blade body 1 is held by the drive motor through the holding hole 101, and is rotated for cutting. The uniformly distributed heat dissipation holes 102 realize cutting heat dissipation during cutting, so that the defect of bending deformation caused by strength reduction of the saw blade base body 1 due to overhigh cutting accumulated temperature is avoided.

In order to improve the cutting effect of the saw blade base body 1, as shown in fig. 1, an alloy blade 2 is arranged on the outer side wall of the saw blade base body 1, and the alloy blade 2 includes an alloy base body 21 connected with the saw blade base body 1 and alloy cutter bits 22 arranged on the outer side wall of the alloy base body 21 at intervals in the circumferential direction. Alloy blade 2 has higher intensity compared with the iron material of saw bit base member 1, and consequently, the same intensity of alloy tool bit 22 that it has is higher, and the cutting edge is sharper, can accelerate ligneous cutting speed when the cutting, also can effectively solve the easy problem of passivating of saw bit base member 1 simultaneously.

In order to further improve the cutting efficiency of the alloy blade 22, as shown in fig. 1, each alloy blade 22 has a multi-stage cutting structure arranged along the rotation direction of the saw blade base body 1, which can effectively increase the number of times that each alloy blade 22 contacts with wood during cutting, accelerate the cutting and crushing of the wood cutting seam, further improve the efficiency of wood cutting, and reduce the problem of dullness of the alloy blade 22.

In order to assist the alloy cutter head 22 to rapidly cut wood, as shown in fig. 1, a chip removal structure is further arranged on the alloy substrate 21, the chip removal structure can discharge the chips generated when the alloy cutter head 22 is in contact with the wood during cutting, and the problem that the whole rotation cutting of the alloy saw blade is blocked due to the fact that the cut chips are blocked between the adjacent alloy cutter heads 22 or clamped between the alloy blade 2 and the saw blade substrate 1 and the wood cutting seam is solved.

Specifically, as shown in fig. 2, the multi-stage cutting structure is formed by a first protruding cutting tip 221 and a second protruding cutting tip 222 which are arranged at intervals at both ends of each alloy cutting tip 22 along the cutting rotation direction (the rotation direction is shown by arrows in fig. 2), and a circular arc transition surface 223 is arranged between the first protruding cutting tip 221 and the second protruding cutting tip 222. When the saw blade matrix 1 drives the alloy blade 2 to integrally rotate at a high speed, the alloy blade heads 22 sequentially contact with the wood to cut at a high speed. When a single alloy cutter head 22 contacts the large wood cutting surface, the single alloy cutter head 22 sequentially passes through the first protruding cutter head 221 and the second protruding cutter head 222 to be in contact with the cutting surface independently, so that the single alloy cutter head 22 can realize two times of cutting operation in sequential contact, the cutting and crushing of wood are accelerated, the cutting efficiency is improved, and the defect that the alloy saw blade is blocked easily is overcome.

In order to avoid the problem that the cut wood chips are clamped between the surfaces of the first and second protruding bits 221 and 222 contacting the wood, thereby affecting the effective cutting of the first and second protruding bits 221 and 222, the side wall of the first protruding bit 221 contacting the alloy base 21 is provided with a chip collecting groove 22 a. The purpose is to collect the cut chips crushed by the first protruding bit 221 by falling into the chip collecting groove 22a along the outer sidewall of the first protruding bit 221, and to prevent the cut chips from being clamped between the second protruding bit 222 and the wood cutting process. The chips cut by the contact of the second protruding bit 222 are discharged backward between the adjacent alloy bits 22, and after the alloy bits 22 in a cutting state are separated from the contact with the cutting surface of the wood by the rotation of the saw blade body, the chips accumulated in the chip collecting grooves 22a and between the adjacent alloy bits 22 are discharged and thrown to the outside of the wood to realize real-time cleaning.

Specifically, as shown in fig. 2, a cutting gap 22b is formed between adjacent alloy tips 22, and the chip discharging structure is an annular groove 21a which is formed in the alloy base 21 and penetrates through each cutting gap 22 b. The wood chips gathered in the chip collecting groove 22a are uniformly discharged into the annular groove 21a along the cutting gap 22b and the wood chips gathered in the cutting gap 22b, and are thrown to the outer side of the wood along the rotation of the saw blade base body for cleaning, so that the problem that the cutting efficiency is influenced due to the excessive wood chips gathered in the chip collecting groove 22a and the cutting gap 22b is avoided.

Because wood can generate a cutting seam in the continuous cutting process, and the cutting seam can cling two side surfaces of the alloy saw blade, so that a large resistance is generated to the rotation of the alloy saw blade, and the problems of large friction and abrasion of the surfaces of the saw blade matrix 1 and the alloy saw blade 2 and burning of a driving motor are solved, as shown in fig. 3, the thickness of the saw blade matrix 1 is gradually reduced towards the center of the saw blade matrix 1 by being close to the alloy matrix 21. On the basis that the alloy cutter head 22 of the alloy saw blade 2 is in contact cutting, the clinging force between the side walls of two sides of the saw blade matrix 1 and the cutting seam is reduced and avoided (because the wood parts of two sides of the cutting seam are not supported after the cutting seam is cut by the saw, two sides of the cutting seam are inclined towards the surface of the saw blade to be close to each other, then two sides of the saw blade are clung to each other, clamping stagnation is caused to the rotation of the saw blade, and the direction of an arrow a in the figure 4 is shown), and the resistance of the alloy saw blade in rotary cutting is reduced. And the saw blade matrix 1 with gradually reduced thickness can effectively match the characteristic that two sides of the cutting seam are inclined and close to each other, and the strength of the saw blade matrix can be kept on the basis that the contact between the saw blade matrix 1 and the cutting seam in a clinging manner is reduced.

The foregoing shows and describes the general principles, principal features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
