Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides two technical schemes: the double-tool-bit woodworking saw blade with the forward and reverse rotation cutting function specifically comprises the following embodiments:

example 1

Including saw body 1, saw body 1's outside fixedly connected with changeover portion 2, changeover portion 2's peripheral ring is established fixedly connected with a plurality of cutting pieces 3, and the equal fixedly connected with in both sides of single cutting piece 3 is cutting edge 4 and No. two cutting edges 5, and is symmetrical each other on cutting piece 3 between cutting edge 4 and No. two cutting edges 5, and No. 4 cutting edges 4 and No. two cutting edges 5 are the arc cutting edges that extend to one side.

The appearance of the first blade 4, the second blade 5 and the cutting blade 3 is integrally provided with a wave shape with concave middle and convex two sides, and the blades of the first blade 4 and the second blade 5 extend to be in streamline intersection with the blades of the first blade 4 and the second blade 5 on the adjacent cutting blade 3.

Alloy particles are fixedly connected to the front surface and the rear surface of the transition piece 2.

The surface of the saw body 1 is provided with a mounting hole 6, and the surface of the saw body 1 is provided with a slag discharging hole 7.

The front side and the rear side of the saw body 1 are fixedly connected with installation pressing blocks 8, and the two installation pressing blocks 8 are positioned at the edge of the installation hole 6.

The outer surfaces of the two installation pressing blocks 8 are fixedly connected with anti-slip pads 9.

Example 2

Including saw body 1, saw body 1's outside fixedly connected with changeover portion 2, changeover portion 2's peripheral ring is established fixedly connected with a plurality of cutting pieces 3, and the equal fixedly connected with in both sides of single cutting piece 3 is cutting edge 4 and No. two cutting edges 5, and is symmetrical each other on cutting piece 3 between cutting edge 4 and No. two cutting edges 5, and No. 4 cutting edges 4 and No. two cutting edges 5 are the arc cutting edges that extend to one side.

And all that is not described in detail in this specification is well known to those skilled in the art.

When the saw is in operation, the first blade 4 and the second blade 5 are arranged on two sides of the cutting blade 3, so that when the saw body 1 integrally rotates to drive the first blade 4 and the second blade 5 to rotate, the first blade 4 and the second blade 5 are arranged as symmetrical arc blades, so that the second blade 5 cuts timber when the saw body positively rotates, the first blade 4 cuts timber when the saw body reversely rotates, bidirectional blade cutting is realized, and the cutting blade 3, the first blade 4 and the second blade 5 integrally have smooth wave arc characteristics, so that the impact of the cutting blade on the cutting rotation is small, the certain degree of cutting wear is relieved, the bidirectional cutting rotation is convenient for cutting, the turning cutting is not needed, a certain manpower is saved, therefore, the problem that the traditional woodworking saw blade is always only a unidirectional arc-shaped blade and cannot cut bidirectionally is solved, in addition, the installation pressing block 8 and the anti-slip pad 9 are arranged at the edge of the installation hole 6, so that the saw body 1 can be tightly twisted by threads during installation, the slipping off-axis phenomenon of the saw body 1 during rotation is prevented by the anti-slip of the anti-slip pad 9, the transition piece 2 is difficult to pull out from materials due to the clamping piece phenomenon during rotation when the transition piece 2 is used for placing alloy particles, the first blade 4 and the second blade 5 on the saw body 1 can polish the cutting edge with certain thickness during rotation cutting, and further the expansion of the cutting edge is difficult to clamp the front side and the rear side of the saw body 1 and the saw body 1 is difficult to rotate, so that the smooth cutting is guaranteed.
