Abstract
It the utility model is related to saw blade, more particularly to a kind of civilian cast-cutting saw slice.Civil safety cast-cutting saw slice, its blade body and the teeth portion around body, teeth portion welds carbide bit, the teeth portion fluting, trench bottom is circular arc pit, corresponding carbide bit bottom is and the arc-shaped convex of groove shape matching, the carbide bit are caught in described pit using the projection and fixed.The utility model avoids cutter head from flying to split and cause harm, improves safety in utilization.
Description
Technical field
It the utility model is related to saw blade, more particularly to a kind of civilian cast-cutting saw slice.
Background technology
People especially pay attention to the security protection theory during daily production and living, the security of electric tool increasingly by
To concern.For commercially available hard alloy saw blade in welding process, the dry joint of carbide bit caused by having accidental cause
Unavoidably, although hard alloy saw blade cutting machine all devises safty shield, in saw bit matrix or hard in design
Still there is certain probability when alloy cutter head flies to split to fly to outside protective cover, cause potential safety hazard.
The content of the invention
The utility model aims to solve the problem that the defects of prior art, there is provided a kind of civil safety cast-cutting saw slice.The utility model
Avoid cutter head from flying to split and cause harm, improve safety in utilization.
To solve the above problems, civil safety cast-cutting saw slice, its blade body and the teeth portion around body, teeth portion welding is hard
Matter alloy cutter head, the teeth portion fluting, trench bottom is circular arc pit, and corresponding carbide bit bottom is and the flute profile
The arc-shaped convex of shape matching, the carbide bit are caught in described pit using the projection and fixed.
Carbide bit and saw bit matrix are formed the concavo-convex structure being inserted into by the utility model, accordingly even when dry joint is not yet
The winged of carbide bit can be caused to split, avoided because cutter head flies to split the generation for the accident of damaging.Further improve hard
The safety that alloy saw blade uses.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
Refer to Fig. 1 the utility model civil safety cast-cutting saw slices, its blade body 1 and the teeth portion 2 around body, teeth portion
Carbide bit 3 is welded, the teeth portion fluting 4, trench bottom is circular arc pit 5, and corresponding carbide bit bottom is
With the arc-shaped convex 6 of groove shape matching, the carbide bit is caught in described pit using the projection and fixed.
