Description
Technical field
This utility model relates to a kind of carpenter's auger and mould thereof.
Background technology
Chinese utility model patent CN2710859Y disclosed " woodworking flat drill " disadvantageously, the rear knife face of its main cutting edge is inclined-plane, if by the mode forged, not only the life-span of mould be substantially reduced and forge after face second-rate, substandard products easily occur.Therefore, this kind of drill bit often uses the mode of cutting and grinding combination to process.It is not difficult to find out, utilizes cutting can reduce the production efficiency of drill bit.Therefore, it would be highly desirable to design carpenter's auger and the machining tool of a kind of new structure.
Utility model content
The purpose of this utility model is to solve the problem that prior art exists the method processing drill using cutting, it is provided that a kind of carpenter's auger and mould.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of carpenter's auger, it is by drill bit, drilling rod and drillstock composition, wherein, described drill bit has drill bit base portion, apex point, circumferential cutting edge and main cutting edge, described apex point system is placed in the end face center of described drill bit base portion, described circumferential cutting edge system is placed in the angle head cylindrical of described drill bit base portion, described main cutting edge system connects described apex point and described circumferential cutting edge, the rear knife face of described main cutting edge is connected with a step, it is characterized in that, described step is formed by connecting by first and the second face, described first is oblique section, and described second is vertical.
As the preferred version of a kind of carpenter's auger, described first is to begin downwardly and outwardly to extend obliquely out after described main cutting edge, and described second end face being to begin to extend to vertically downward described drill bit base portion from the feather edge of described first.
As the preferred version of a kind of carpenter's auger, cross section forged into by described drillstock system contracting bar is hexagon or circle.The wire drawing of described drilling rod system becomes cross section to be circular.Described apex point, described circumferential cutting edge and described main cutting edge are all with forging molding of mould.Described drill bit is up big and down small.
As the preferred version of a kind of carpenter's auger, the end face of described drillstock has the centre of location.
This utility model also provides for the mould of a kind of carpenter's auger, the above-mentioned drill bit of molding in the way of forging, it is characterised in that including die ontology, described die ontology has die cavity, and the shape of described die cavity is consistent with the shape of described drill bit.
As the preferred version of the mould of a kind of carpenter's auger, described die cavity has the apex point holding part corresponding with the described apex point circumferential cutting edge holding part corresponding with described circumferential cutting edge and the main cutting edge holding part corresponding with described main cutting edge.
Compared with prior art, this utility model at least has the advantage that processing technique is simple, saves lathe process, promotes working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model one embodiment.
Fig. 2 is the machining sketch chart of this utility model one embodiment.
Detailed description of the invention
With embodiment, this utility model is elaborated below in conjunction with the accompanying drawings.
Refer to Fig. 1 and 2, a kind of carpenter's auger, it is by drill bit 1, drilling rod 2 and drillstock 3 form, wherein, described drill bit has drill bit base portion 11, apex point 12, circumferential cutting edge 13 and main cutting edge 14, described apex point system is placed in the end face center of described drill bit base portion, described circumferential cutting edge system is placed in the angle head cylindrical of described drill bit base portion, described main cutting edge system connects described apex point and described circumferential cutting edge, the rear knife face of described main cutting edge is connected with a step, described step is formed by connecting by the first face 141 and the second face 142, described first is oblique section (in the present embodiment, oblique angle is 45 °), and described second is vertical.Described first is to begin downwardly and outwardly to extend obliquely out after described main cutting edge, and described second end face being to begin to extend to vertically downward described drill bit base portion from the feather edge of described first.The reason of above-mentioned design is, protects the mold use life-span.Above-mentioned oblique and vertically to all with the end face of described drill bit base portion as reference plane.Additionally, the outer peripheral face of described drill bit is the conical surface, under being above slightly more than.
The mould 4 of a kind of carpenter's auger, the above-mentioned drill bit of molding in the way of forging, its structure includes die ontology, and described die ontology has die cavity, and the shape of described die cavity is consistent with the shape of described drill bit.Specifically, described die cavity has the apex point holding part corresponding with the described apex point circumferential cutting edge holding part corresponding with described circumferential cutting edge and the main cutting edge holding part corresponding with described main cutting edge.
In prior art, main cutting edge is the most first processed into plane, the more direct inclined-plane being cut into about 40 °, and adds man-hour by the way of forging, does not i.e. use cutting, directly grinds with grinding machine the most permissible.Size needed for the principle of the size directly use contracting bar that afterbody is on-demand or Wire Drawing one-tenth, hexagon or circle.Save cutting one procedure.Adding at mould at this brill embryo tail and be directly processed into a centre bore man-hour, the effect in this hole is indispensable at grinding machine lathe, in the concentricity of car mill.Originally formed by artificial lathe process, and completed in mould now.Above drill bit finally will be through grinding machine completion of processing.
Below only have expressed embodiment of the present utility model, it describes more concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
