Abstract
The utility model discloses a circular saw web which comprises a saw web cutter body. a central hole is arranged in the center of the saw web cutter body, sawteeth are evenly arranged at the edge of the circular saw web cutter body, an alloy cutter head is arranged on the sawteeth, dovetail-shaped tooth backs are evenly punched at the backs of the sawteeth, and an angle of 18 degrees is formed between a cutter face of the alloy cutter head and a longitude line from the alloy cutter head to the central hole. The dovetail-shaped tooth backs are evenly punched on the sawteeth of the circular saw web, so that the circular saw web is prevented from bouncing in cutting. Thus, safety of construction workers is guaranteed, and safety is improved. Furthermore, the alloy cutter head is positioned on the sawteeth, the angle of 18 degrees is formed between the cutter face of the alloy cutter head and the longitude line from the alloy cutter head to the central hole, cutting capacity of the circular saw web on hard blocks difficult to cut is enhanced, and the circular saw web is further prevented from bouncing in cutting.
Description
Technical field
The utility model relates to a kind of cutting saw blade, relates in particular to a kind of saw blade.
Background technology
Saw blade is the general cutting tool for the processing of stone material, timber, metal, plastics etc. solid material blank, the saw blade bounce-back owing to having the lump that is difficult to cut in sheet material, easily occurs in existing saw blade when cuts sheet material, the situation that sheet material falls back is easily given workmen's cause danger.
Chinese patent notification number CN101658960A on March 3 2010 day for announcing, discloses a kind of saw blade, comprise blade body and mount pad, mount pad is the circular bowl body, offers connecting hole on its diapire, its top end wall is along being riveted together with blade body, the use that can be close to the ground of this saw blade, the scope of application is wide, and blade body and bowl-type mount pad can adopt two kinds of different materials to make, not only reduced production cost, and increased the rigidity of semicircle saw blade, reduce vibrations, noise-decreasing.But the saw blade bounce-back owing to having the lump that is difficult to cut in sheet material, easily occurs in this saw blade when cuts sheet material, the situation that sheet material falls back is easily given workmen's cause danger.
The utility model content
The purpose of this utility model is to provide a kind of saw blade with anti-bounce-back design, solved existing saw blade when cuts sheet material, owing to having the lump that is difficult to cut in sheet material, the saw blade bounce-back has occured easily, the situation that sheet material falls back, the problem of easily giving workmen's cause danger.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of saw blade, comprise the saw blade cutter hub, the center of saw blade cutter hub is provided with centre bore, described saw blade cutter hub edge evenly is provided with sawtooth, be provided with alloy cutter head on sawtooth, on the sawtooth back evenly punching press the swallow-tail form back of tooth is arranged, the knife face of alloy cutter head and alloy cutter head become 18 to spend the angle to the warp of central hole.On the sawtooth of this saw blade, even punching press has the swallow-tail form back of tooth, prevent saw blade bounce-back when cutting, guarantee workmen's safety, improve security, and alloy cutter head is set on sawtooth, the knife face of alloy cutter head and alloy cutter head become 18 degree angles to the warp of central hole, increase the cutting power to the lump that is difficult to cut of saw blade, guarantee that further saw blade can not rebound when cutting.
As preferably, on described saw blade cutter hub evenly punching press expansion slot is arranged.The impact of expanding with heat and contract with cold saw blade being produced when preventing saw blade production and cutting by expansion slot.
The beneficial effects of the utility model are: the design of this saw blade can guarantee workmen's safety in case circle stops saw blade bounce-back when cutting, improves security.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
In figure: 1, saw blade cutter hub, 2, centre bore, 3, expansion slot, 4, the swallow-tail form back of tooth, 5, alloy cutter head, 6, sawtooth.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figure 1, a kind of saw blade, comprise saw blade cutter hub 1, the center of saw blade cutter hub is provided with centre bore 2, saw blade cutter hub edge evenly is provided with sawtooth 6, is provided with alloy cutter head 5 on sawtooth, on the sawtooth back evenly punching press the swallow-tail form back of tooth 4 is arranged, the knife face of alloy cutter head and alloy cutter head become 18 degree angles to the warp of central hole, on the saw blade cutter hub evenly punching press expansion slot 3 is arranged.
On the sawtooth of this saw blade, even punching press has the swallow-tail form back of tooth, prevent saw blade bounce-back when cutting, guarantee workmen's safety, improve security, and alloy cutter head is set on sawtooth, the knife face of alloy cutter head and alloy cutter head become 18 degree angles to the warp of central hole, increase the cutting power to the lump that is difficult to cut of saw blade, guarantee that further saw blade can not rebound when cutting.
Above-described embodiment is a kind of better scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
Claims (2)
