Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in figure 1, a kind of modified saw blade of the utility model, it is directed to product of cutting metal material and designed, its
Including saw bit matrix 10, the middle part of saw bit matrix 10 is provided with the centre bore 20 for fixing saw bit matrix 10, in saw blade base
Multigroup 30 groups of sawtooth is evenly arranged with the outer circumference of body 10, every group of 30 groups of sawtooth includes three sawtooth 30, for convenience of managing
Solution, three sawtooth 30 in every group are divided into the first sawtooth 31, second saw from the front to the back by the rotation direction of saw bit matrix 10
The sawtooth 33 of tooth 32 and the 3rd, the tooth form of the first sawtooth 31 is flat tooth, and the tooth form of the second sawtooth 32 is left chamfered teeth, i.e., in the second saw
The left side of tooth 32 is provided with left chamfering 32a, and the tooth form of the 3rd sawtooth 33 is right chamfered teeth, the i.e. right side in the 3rd sawtooth 33
Right chamfering 33a is provided with, the sawtooth 30 of arbitrary neighborhood two is spaced from each other and all sawtooth 30 are welded to connect with saw bit matrix 10, is owned
The tooth Gao Jun of sawtooth 30 is on same circumference.
This saw blade is applied to cutting metal product, cuts and designs specifically for metal product, but can also cut wood simultaneously
The product of matter or other materials, compared with traditional saw blade, this saw blade is as a result of said structure, three sawtooth in every group
30 are respectively adopted dissimilar tooth form, and a variety of tooth forms of sawtooth 30 cooperate so that the cutting face after product cutting is bright and clean, for single
For sawtooth 30, it is not easy tipping, so as to extend the service life of whole saw blade.
On the basis of said structure, the utility model has made further improvement and refinement to it.
As shown in Figure 1 and Figure 2, the chip pocket 40 for accommodating chip is provided between the sawtooth 30 of arbitrary neighborhood two.
The setting of the chip pocket 40 so that chip caused by cutting product can be entered in chip pocket 40, avoid chip
Cutting around buckle for sawtooth 30 is deposited in, prevents chip from influenceing cutting of the sawtooth 30 to product, effectively raises cutting for product
Cut quality.
As shown in Figure 1 and Figure 2, the blocking part 50 for propping up the sawtooth 30 is provided with the rear of each sawtooth 30, that is,
Say, the blocking part 50 is arranged on each sawtooth 30 side opposite with the rotation direction of saw bit matrix 10, and the blocking part 50 is by sawing
The bottom of tooth 30 is to its top extension and close to the top of sawtooth 30.
By setting blocking part 50 so that after sawtooth 30 contacts with product, the stress of sawtooth 30 can be transferred into blocking part
On 50, so as to improve the resistance of sawtooth 30, sawtooth 30 is avoided to produce deformation.
As shown in figure 1, being provided with several noise reduction heat-sink units on the saw bit matrix 10, each noise reduction unit is included in
The silencing groove 60 formed on saw bit matrix 10 by laser cutting, the silencing groove 60 can be any trend and arbitrary shape, that is, disappear
The bearing of trend of sound groove 60 is not specified by, and the global shape of silencing groove 60 is also not specified by, and can is arc line shaped or is in
The shaped form of S-shaped bending, heat emission hole 61, the heat emission hole 61 and silencing groove 60 are respectively arranged with the both ends of each silencing groove 60
Communicate.
For saw bit matrix 10 during quick rotation, it produces friction with air, it will usually caused larger noise, and
The setting of silencing groove 60, the effect to abate the noise can be played, so that noise when saw bit matrix 10 works is smaller, and sawed
Sheet matrix 10 and heat caused by product friction, can be dissipated by the heat emission hole 61, avoid the temperature mistake of saw bit matrix 10
It is high and influence its normal use.
As shown in figure 1, multiple expansion slots 70 are provided with the saw bit matrix 10, it is preferred that expansion slot 70 have four and
Set on saw bit matrix 10 in " ten " font, each expansion slot 70 is from the corresponding bottom of chip pocket 40 to the middle part of saw bit matrix 10
Extension, the receiving hole 71 communicated with expansion slot 70, the appearance are provided with each expansion slot 70 close to one end of saw bit matrix 10
Receive and copper tack 72 is installed in hole 71.
When saw bit matrix 10 rotates, it is contacted with product can produce certain resistance, and the effect of expansion slot 70 is to whole
Saw bit matrix 10 plays certain cushioning effect, and expansion slot 70 is avoided that the rigid contact power mistake of saw bit matrix 10 and product
Greatly, so as to be effectively protected saw bit matrix 10, make its without damage, installation copper tack 72, serves balance in receiving hole 71
The effect of whole saw bit matrix 10, prevents saw bit matrix 10 from being rocked in rotation process, improves when saw bit matrix 10 rotates
Stability.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
