Abstract
The utility model discloses a lig saw, which comprises a pedestal, a shell, a motor and a saw blade, wherein the motor is provided with a cooling fan; an accommodating cavity is formed in the shell; the cooling fan is arranged in the accommodating cavity to centralize air flow produced by the cooling fan; the accommodating cavity is connected with a first end of an air flow guide pipe; a second end of the air flow guide pipe extends to the space in front of the pedestal; and an opening at the second end of the air flow guide pipe corresponds to the saw blade, so that air flow produced by the cooling fan blows scraps produced by cutting a workpiece through the saw blade away. The lig saw has the advantages of low cost, convenience in use, high humanization, obviously improved working efficiency of workers and machines.
Description
Technical field
The utility model relates to a kind of sweep-saw, relates in particular to a kind of sweep-saw that can remove the cutting chip automatically.
Background technology
Sweep-saw is a kind of electric tool commonly used, and it has obtained extensive use with efficient height, characteristics simple to operate.Sweep-saw is when cut workpiece, and producing has a large amount of chips, as this type of chip of untimely removing, will influence operator's sight line, reduces cutting efficiency, also may cause miscut.The method of this type of chip of removing has mouth to blow and increases blowning installation at present, and it is not only dangerous that mouth blows mode, and under the efficient, chip is removed poor effect; The mode that increases other blowning installations has then obviously improved the sweep-saw application cost, and makes the sweep-saw operation become complicated.
Summary of the invention
The purpose of this utility model is to provide a kind of sweep-saw, to solve the problem that can not remove the cutting chip automatically that existing sweep-saw exists.
In order to realize the purpose of this utility model, the sweep-saw that the utility model provides comprises base, housing, motor and saw blade, described motor is provided with heat emission fan, wherein, be provided with a containing cavity in the described housing, described heat emission fan is located at the air-flow to concentrate described heat emission fan to produce in the described containing cavity, first end of a described containing cavity and an airflow duct is connected, second end of described airflow duct extends to the place ahead of described base, and second end opening of described airflow duct corresponding to described saw blade so that the chip that the air-flow that described heat emission fan produces produces when blowing away described saw blade cut workpiece.
According to a kind of preferred implementation of above-mentioned sweep-saw, wherein, the head of described base shrinks pointed.
According to a kind of preferred implementation of above-mentioned sweep-saw, wherein, the below of described base is provided with a strip groove, and the line of symmetry of described groove and described saw blade are in same plane.
By analyzing as can be known, the sweep-saw that the utility model provides is after the air-flow of concentrating motor radiating, this air-flow is guided to the contact position of saw blade and workpiece, the chip that produces when blowing away cut workpiece, need not to increase extras and operation in the process of removing chip, with low cost, easy to use, have hommization, the operating efficiency of workman and machine significantly improves.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the structural representation of the base of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 schematically shows the structure of the utility model preferred embodiment, and as shown in it, this preferred embodiment comprises housing 1, motor 2, saw blade 7 and base 8, and the end of motor 2 is provided with heat emission fan 4.
The chip that produces during with cut workpiece for the air-flow that utilizes heat emission fan 4 blows away automatically, be provided with a containing cavity 3 in the housing 1 of this preferred embodiment, heat emission fan 4 is located at the air-flow to concentrate heat emission fan 4 to produce in the containing cavity 3, first end of containing cavity 3 and airflow duct 5 is connected, second end of airflow duct 5 extends to base the place ahead of housing 1, and second end opening 6 of airflow duct 5 is corresponding to saw blade 7, second end opening 6 is located on the base 8, as shown in Figure 2, the air-flow of heat emission fan 4 generations of containing cavity 3 collections is via airflow duct 5 like this, blow to the contact position of saw blade 7 and workpiece, the chip that produces when blowing away saw blade 7 cut workpiece, the flow direction of the air-flow of heat emission fan 4 is shown in the arrow among Fig. 1.
For the radiating airflow that improves motor 2 blows away the efficient of chip automatically, the polycrystalline substance of this preferred embodiment base as shown in Figure 2, the head of base 8 shrinks pointed, and the head central authorities of base 8 are provided with a gap 81, and saw blade 7 is arranged in this gap 81.In addition, the below of base 8 also is provided with a strip groove 82, and the line of symmetry of groove 82 and saw blade 7 are in the same plane.The chip that the pointed triangle design of base 8 heads can make radiating airflow blow and not fall separates from its both sides, and the flat-head shape base of avoiding prior art talus accumulation together.Groove 82 can make head part from not chip from wherein flowing through.As seen chip stopping workman's sight line can be better avoided in the design of the pointed head of base 8 and groove 82.
In sum, the energy of the ingenious utilization of the utility model own makes full use of the air-flow of motor radiating, and this air-flow is guided to sweep-saw base the place ahead, alignment pieces and saw blade contact position, when work, can blow away the chip that produces in the cutting process timely and effectively, thereby chip is removed from workman's sight line, improve the accuracy and the operating efficiency of processing greatly, and do not increase cost substantially, do not change the structure of existing sweep-saw substantially yet, have tangible cost advantage.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spiritual essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
