Abstract
The utility model provides a special large-diameter hole drilling tool for thin plates. The special large-diameter hole drilling tool comprises a plurality of front tool cutting blades. Each front tool cutting blade is composed of at least two front cutting blade units axially distributed along the tool. In the adjacent front cutting blades, the front cutting blade unit close to the front end of the tool is provided with small outer diameter. By the front cutting blade units, the special large-diameter hole drilling tool can cut layer by layer, drilled hole diameter is gradually increased from the front end of the tool until the hole diameter is complied with the requirement, cutting force is reduced layer by layer, and output power of an electric drill is reduced, and efficiency of large-diameter holes processed on the thin plates is improved. Further, the special large-diameter hole drilling tool for the thin plates has the advantages of convenience and simplicity in manufacture and is applicable to popularization.
Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of thin plate large diameter borehole dedicated tool.
Background technology
In mechanical industry production reality, it is to hole at thin plate that a large amount of machine parts is arranged, and these plate areas and aperture are all bigger, are not suitable for processing at lathe, if process at lathe, efficient is very low.If adopt electric hand drill and existing cutter to process, can only progressively change the big cutter of diameter again, until till the required aperture, therefore cause working (machining) efficiency also very low earlier with the little cutter processing of diameter.If directly adopt the processing of major diameter cutter, because cutting at one time amount and cutting force are bigger, electric hand drill can't satisfy its power requirement.
The utility model content
The purpose of this utility model is to provide a kind of thin plate large diameter borehole dedicated tool, and this dedicated tool makes the working (machining) efficiency of the large diameter hole on the large-area thin plate improve greatly.
For achieving the above object, the utility model has adopted following technical scheme:
Comprise some Tool in Cutting front edges, described Tool in Cutting front edge is made up of at least two cutting front edge unit along the cutter axial distribution, and in the adjacent cutting front edge unit, the cutting front edge unit of close cutter front end has less external diameter.
Described Tool in Cutting front edge is three.
The anterior angle of described cutting front edge unit and relief angle are zero.
The beneficial effects of the utility model are:
Dedicated tool described in the utility model successively cuts by cutting front edge unit, begin to increase gradually boring aperture from the cutter front end, until reaching desired aperture size, cutting has successively reduced cutting force, reduced the electric drill power output, improved the efficient at thin plate processing large diameter hole, and dedicated tool described in the utility model has easily manufactured, simple advantage, the suitable popularization.
Description of drawings
Fig. 1 is the front view of dedicated tool described in the utility model;
Fig. 2 is the vertical view of dedicated tool described in the utility model;
Fig. 3 is the side view of dedicated tool described in the utility model;
Among the figure: 1 is cutting front edge unit, and 2 is the Tool in Cutting front edge, and d is external diameter.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises some Tool in Cutting front edges 2, described Tool in Cutting front edge 2 is three, described Tool in Cutting front edge 2 is made up of at least two cutting front edge unit 1 along the cutter axial distribution, the anterior angle of described cutting front edge unit 1 and relief angle are zero, in the adjacent cutting front edge unit 1, the cutting front edge unit 1 of close cutter front end has less external diameter.
Embodiment
In order to improve working (machining) efficiency, the utility model is a kind of thin plate large diameter borehole dedicated tool for electric hand drill has designed.This cutter can be made with high-speed steel, is processed into the external diameter that varies in size at lathe earlier, and whole tool bodies is left three place's Tool in Cutting front edges then, and anterior angle is zero, and relief angle also is zero.This cutter can be used on the general electric hand drill, has increased the boring scope of general electric hand drill, be particularly suitable for boring large diameter hole at thin plate, and this kind cutter is easily manufactured, simple, the suitable popularization.
Claims (3)
1. thin plate large diameter borehole dedicated tool, it is characterized in that: comprise some Tool in Cutting front edges (2), described Tool in Cutting front edge (2) is made up of at least two cutting front edge unit (1) along the cutter axial distribution, in the adjacent cutting front edge unit (1), the cutting front edge unit (1) of close cutter front end has less external diameter.
2. according to the described a kind of thin plate large diameter borehole dedicated tool of claim 1, it is characterized in that: described Tool in Cutting front edge (2) is three.
