Description

Reinforced saw blade

Technical Field

The utility model belongs to the technical field of saw blades, and particularly relates to a reinforced saw blade.

Background

The saw bit is applied to each processing field, and among the prior art, to the circular saw blade that has certain thickness, its cutting capacity and shock-absorbing capacity are poor, bring a great deal of inconvenience for production and processing, cause the saw bit short-lived, single design inefficiency moreover, intensity is not enough, and the durability is relatively poor.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a reinforced saw blade, in which the first and second blades of the saw tooth portion are matched with each other to enhance cutting, and the silencing pull slot is used for damping and silencing to avoid the trouble of low damping capability of the saw blade in the past.

In order to solve the technical problem, the utility model discloses a reinforced saw blade, which comprises a saw blade matrix, wherein the saw blade matrix is provided with a central through hole; the equal division ring is arranged on 4 silencing pull grooves of the saw blade matrix; the sawtooth parts are positioned between the silencing pull grooves and are separated by chip removal grooves; the sawtooth part is provided with a first cutter head positioned at one end and a second cutter head positioned at the center, the second cutter head is radially higher than the first cutter head, and ridge parts inclining downwards are arranged on two sides of the second cutter head.

According to an embodiment of the present invention, the silencing pull groove includes a straight groove opening extending to the bottom of the chip discharge groove; and a round notch connected with the straight notch.

According to an embodiment of the present invention, the second cutting head is 1.5mm to 2.5mm higher than the first cutting head in the radial direction.

According to an embodiment of the present invention, the inner ring of the saw-tooth portion has a hardened ring layer, and the hardened ring layer is coated with a hardened coating.

Compared with the prior art, the utility model can obtain the following technical effects:

first tool bit and second tool bit through sawtooth portion mutually support, the reinforcing cutting, and the amortization kerve shock attenuation amortization avoids the trouble that saw bit cutting shock-absorbing capacity is low in the past simultaneously.

Of course, it is not necessary for any one product in which the utility model is practiced to achieve all of the above-described technical effects simultaneously.

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the utility model and not to limit the utility model. In the drawings:

FIG. 1 is a schematic view of a reinforced saw blade according to an embodiment of the present invention.

Reference numerals

The saw blade comprises a saw blade base body 10, a central through hole 11, a silencing pull groove 20, a straight notch 21, a round notch 22, a sawtooth part 30, a first tool bit 31, a second tool bit 32, a ridge part 33, a chip groove 40 and a hardening ring layer 50.

Detailed Description

The embodiments of the present invention will be described in detail with reference to the accompanying drawings and examples, so that how to implement the technical means for solving the technical problems and achieving the technical effects of the present invention can be fully understood and implemented.

Referring to fig. 1, fig. 1 is a schematic view of a reinforced saw blade according to an embodiment of the utility model. As shown in the drawings, a reinforced saw blade includes a blade body 10, the blade body 10 having a central through hole 11; the 4 silencing pull grooves 20 are arranged on the saw blade matrix 10 in an equant and annular mode; and a plurality of saw teeth 30 located between the silencing pulling grooves 20, the saw teeth 30 being separated by junk slots 40; the serrated portion 30 has a first cutting head 31 at one end and a second cutting head 32 at the center, the second cutting head 32 is radially higher than the first cutting head 31, and two sides of the second cutting head 32 have downwardly inclined ridges 33.

In one embodiment of the present invention, the central through hole 11 of the saw blade body 10 is used for installation, 4 silencing pulling grooves 20 are annularly arranged on the edge to separate a plurality of saw teeth 30, and meanwhile, the chip removal grooves 40 are arranged between the saw teeth 30 and are formed in a U shape to facilitate chip removal. The front end of the sawtooth part 30 along the cutting direction is provided with a first cutter head 31, the center of the sawtooth part is provided with a second cutter head 32, the first cutter head 31 and the second cutter head 32 have certain height difference, the first cutter head 31 is lower than the second cutter head 32, double-stage cutting is achieved, cutting capacity is enhanced, meanwhile, cutting depth is increased relatively, and efficiency is improved. The second tool bit 32 is provided with ridges 33 on both sides thereof, which are gradually lowered for strength and durability.

The silencing pull groove 20 comprises a straight notch 21 extending to the bottom of the chip groove 40; and a circular notch 22 connected with the straight notch 21, and the circular notch are matched to absorb shock, resist stress, absorb shock and reduce noise and improve durability.

Preferably, the second tool bit 32 is radially higher than the first tool bit 32 by 1.5 mm-2.5 mm, so that the cutting stroke is increased, the buffering of cutting is reduced, and the durability is improved.

The inner ring of the sawtooth part 30 is provided with a hardened ring layer 50, and the hardened ring layer 50 is coated with a hardened coating to improve the hardening strength.
