Abstract
The utility model relates to a kind of machining tool, particularly a kind of durable type quick drill hair style rotary file.A kind of file, comprise file head and staight shank drilling rod body, it is characterized in that: the front end of described spherical file is provided with bullet shaped alloy head, described staight shank drilling rod is provided with U-type groove.The utility model can reduce the wearing and tearing of blade, can increase the discharge of heat dissipation capacity, extends cutting-tool's used life.
Description
Technical field
The utility model relates to a kind of rough machinedly repaiies hole instrument, particularly a kind of durable type quick drill hair style rotary file.
Background technology
carbide rotary tool uses extensively, and have use, Be very effective at industrial departments such as machinery, automobile, boats and ships, chemical industry, technique engravings, main application has: the various metal die die cavity of fine finishining, as footwear mould etc.Various metal and nonmetallic technique engraving, the engravings such as process gift.Cleaning casting, forging, the overlap of weldment, burr, weld seam, as Ji Zhu factory, shipyard, automobile factory etc.The chamfering rounding of various component of machine and groove processing, cleaning pipeline, the bore area of fine finishining machine components, as machinery plant, repair shop etc.The smoothing of impeller channel part, as automobile engine factory.But due to spherical file not having bullet-shaped alloy head, cause the blade on spherical file to be operationally easy to workpiece to be machined wearing and tearing, reduce service life.
Utility model content
The purpose of this utility model is to provide one and effectively reduces edge wear, the roughing quick drill hair style rotary file increased the service life.
The technical solution adopted in the utility model is:. a kind of durable type quick drill hair style rotary file, comprise bullet-shaped alloy head, spherical file and staight shank drilling rod, its innovative point is: described staight shank drilling rod is cylinder, spherical file is set in one end of described staight shank drilling rod, described spherical file arranges bullet-shaped alloy head.
Further, the length of described staight shank drilling rod is 15 ~ 20cm.
Further, drilling rod is arranged the U-type groove of long 6 ~ 10cm, wide 2 ~ 5cm.
Further, described spherical file diameter is 4 ~ 8cm, and arranges circulating type blade.
Further, described spherical file is arranged grow 5 ~ 8cm, wide 3 ~ 6cm bullet-shaped alloy head.
The beneficial effects of the utility model are:
1, bullet shaped alloy head described in the utility model adopts carbide alloy to be material, sturdy and durable, operationally effectively can reduce the wearing and tearing of processing work for blade, in some special circumstances, effectively can locate, guarantee the stability of drill bit entirety.
2, spherical file can be good at the surface of laminating processing work, makes finished surface can be good at processing.The blade that spherical file is arranged is very sharp, effectively can remove burr, burr.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 is the structural representation of the utility model quick drill hair style rotary file.
In figure: 1 is bullet shaped alloy head, 2 is spherical file main body, and 3 is blade, 4 staight shank drilling rods, and 5 is U-type groove.
Fig. 2 is the top view of spherical file knife structure.
Detailed description of the invention
Drill-bit type rotary file as shown in Figure 1, is made up of bullet shaped alloy head 1, spherical file main body 2 and staight shank drilling rod 4.
The structure of drill-bit type rotary file is as shown in Figure 1: alloy head 1 is bullet-shaped, long 5 ~ 8cm, wide 3 ~ 6cm, and the design of this structure is mainly considered to add man-hour, reduces the wearing and tearing of processing work for blade.
The structure of drill-bit type rotary file is as shown in Figure 1: file is ball shape, and diameter is 4 ~ 8cm, and the design of this structure mainly considers that spherical file can be good at processing work of fitting.
The structure of drill-bit type rotary file is as shown in Figure 1: staight shank drilling rod 4 is cylinder, its length is 15 ~ 20cm, drilling rod is arranged the U-type groove of long 6 ~ 10cm, wide 2 ~ 5cm, handling and the use of staight shank drilling rod 4 are mainly considered in the design of this structure, too short being not easy grips, the poor stability of oversize use, and U-type groove can not only make installation more firm, and contribute to the heat radiation of drill-bit type rotary file, increase the service life.
During processing work, the front end of the capable file main body 2 of described ball is provided with bullet shaped alloy head 1, and bullet-shaped alloy head can make processing easier, and can play the effect of location in a special case, can reduce the wearing and tearing of processing work for blade.Described file main body is provided with blade 3, and blade has certain gap between blade, and the rotary middle spindle of blade is in a center of symmetry, and when processing work, chip can well be discharged.Described staight shank drilling rod 4 is provided with U-type groove 5, not only can well ensure that drill-bit type rotary file is arranged on the fastness of electric tool, and can increase the heat exhaust of drill bit, increase the service life.
the above is preferred embodiment of the present utility model, can not limit the interest field of the utility model with this.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified or equivalent replacement, do not depart from protection domain of the present utility model.
