Description
Technical field
The utility model is related to cutter art, refers in particular to a kind of shaping drill mill.
Background technology
Cutter is the instrument for machining in machine-building, also known as cutting element.Because most of cutter is
Machine, it is substantially all for cutting metal material, so " cutter " one word is typically just interpreted as metal cutting tool.But material
Scientific development, various materials have also been able to extensive use in the production and processing of product, such as：Engineering plastics and carbon fiber are multiple
Condensation material etc..Cutter can be divided into by the form of workpiece machining surface：Process cutter, aperture knife tool, the screw thread of various outer surfaces
Process tool, gear cutting tool and cutting off tool etc. are several.
In the prior art, milling cutter and drill bit are two kinds of independent cutters, when needing to carry out drilling and milling, it is necessary to back and forth
Cutter is changed, to using making troubles.Although having occurred in that drill mill at present, it can drill can also carry out milling, however,
Current this drill mill typically is only capable of carrying out either shallow milling, it is difficult to realize depth milling, uses still inconvenience.
The content of the invention
In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide a kind of shaping and bores the utility model
Milling cutter, it can be drilled, while either shallow and depth milling can also be carried out.
To achieve the above object, the utility model is using following technical scheme：
One kind shaping drill mill, includes drill bit processing bar, Milling Process bar and the handle of a knife for being integrally formed connection successively
Bar；There is spiral grooves and helicoid on drill bit processing bar, the spiral grooves and helicoid by drill bit processing bar front end to
Rear end extends spirally in same direction, and the both side edges of helicoid are convexly equipped with spiral cutting edge, and the front end face of drill bit processing bar is convex
Multiple tiltedly blades are provided with, end of the plurality of oblique blade respectively with spiral grooves and two spiral cutting edges is connected；Milling Process bar
All sides are convex to be provided with multiple straight line swords for depth milling.
Preferably, the external diameter of the drill bit processing bar is identical with the external diameter of handle of a knife bar, and the external diameter of the Milling Process bar is big
In the external diameter and the external diameter of handle of a knife bar of drill bit processing bar.
Preferably, the length of the length more than Milling Process bar of the drill bit processing bar.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme understands：
Workpiece can be drilled by coordinating oblique blade, spiral grooves, helicoid and spiral cutting edge, and chip removal is suitable
Freely, chip efficiency is improved, the milling of either shallow can be carried out to workpiece individually with spiral cutting edge, and workpiece can entered using straight line sword
Row depth milling, to using bringing more facilities.
More clearly to illustrate architectural feature of the present utility model and effect, come right with specific embodiment below in conjunction with the accompanying drawings
The utility model is described in detail.
Brief description of the drawings
Fig. 1 is the front view of the preferred embodiment of the utility model.
Accompanying drawing identifier declaration：
10th, drill bit processing bar 11, spiral grooves
12nd, helicoid 13, spiral cutting edge
14th, oblique blade 20, Milling Process bar
21st, straight line sword 30, handle of a knife bar
Specific embodiment
Refer to shown in Fig. 1, that show the concrete structure of the preferred embodiment of the utility model, include successively one
The drill bit of body formed connection processes bar 10, Milling Process bar 20 and handle of a knife bar 30.
Drill bit processing bar 10, Milling Process bar 20 and handle of a knife bar 30 are hard alloy material, on drill bit processing bar 10
With spiral grooves 11 and helicoid 12, the spiral grooves 11 and helicoid 12 process the front end rear end edge of bar 10 by drill bit
Identical direction extends spirally, and the both side edges of helicoid 12 are convexly equipped with spiral cutting edge 13, and the front end face of drill bit processing bar 10 is convex
Multiple tiltedly blades 14 are provided with, end of the plurality of oblique blade 14 respectively with the spiral cutting edge 13 of spiral grooves 11 and two is connected.
All sides of the Milling Process bar 20 are convex to be provided with multiple straight line swords 21 for depth milling.
In the present embodiment, the external diameter of the drill bit processing bar 10 is identical with the external diameter of handle of a knife bar 30, the Milling Process bar
20 external diameter is all higher than the external diameter of drill bit processing bar 10 and the external diameter of handle of a knife bar 30, and the length of the drill bit processing bar 10 is more than milling
Cut the length of processing bar 20.
Design focal point of the present utility model is：By coordinating oblique blade, spiral grooves, helicoid and the spiral cutting edge can be to work
Part is drilled, and chip removal is smooth, improves chip efficiency, can carry out the milling of either shallow to workpiece individually with spiral cutting edge,
And depth milling can be carried out to workpiece using straight line sword, to using bringing more facilities.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and can not by any way be construed to the limitation to the utility model protection domain.Based on explanation herein,
Those skilled in the art associates other specific embodiments of the present utility model by would not require any inventive effort,
These modes are fallen within protection domain of the present utility model.
