Description
Technical field
The present invention relates to a kind of hole machining tool, particularly a kind of forming flat drill.
Background technology
At present, when processing has the forming hole of labyrinth, generally need to use much knives tool, method is first to hole at the end, with the counterboring of different-diameter, hole again, this method is because number of changing knife is many, and the degree of depth of different cutters is difficult to control, and working (machining) efficiency is very low, the overproof rate of product is high, simultaneously also high to user's specification requirement, and drill bit chip removal of the prior art space is little, easily cause tool wear and crumble, and chip removal freely can not produce burr and cut at the endoporus processing and port, need tool changing deburring again, reduced production efficiency.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of rational in infrastructure, process forming flat drill simple and easy, easy to use.
For achieving the above object, the present invention is by the following technical solutions:
A kind of forming flat drill of the present invention, comprise integrated handle of a knife and blade, described handle of a knife is cylindrical staight shank, described blade is the design of flat double-sided symmetrical, between handle of a knife and blade, be provided with cambered surface chip area, described blade comprises the one-level blade setting gradually, secondary blade, three grades of blades, level Four blade and Pyatyi blade, its width increases step by step, one-level blade is arranged at foremost, Pyatyi blade links with described handle of a knife, described one-level blade, secondary blade, three grades of blades, the knife edge of level Four blade and Pyatyi blade is provided with cutting edge, described one-level blade top is provided with a blade tip, between described secondary blade and three grades of blades, be provided with fillet sword, described fillet sword is arc interface.
Further, the junction of described secondary blade and three grades of blades be 12 ° of angle settings with vertical direction.
Further, described chip area is arranged at described Pyatyi blade and described handle of a knife junction, and with cambered surface transition.
Further, the junction of described one-level blade and secondary blade at right angles arranges.
Further, the junction of described three grades of blades and level Four blade at right angles arranges.
Further, the junction of described level Four blade and Pyatyi blade at right angles arranges.
Further, the blade tip angle of described blade tip is 120 °.
Further, described handle of a knife and blade coaxially arrange.
Beneficial effect of the present invention is: the present invention is rational in infrastructure, and cutter bulk strength is better, can effectively improve working (machining) efficiency, can one-shot forming for complicated endoporus, simplify work flow, and the product glossiness processing is high, and uniformity is high.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the local A structure for amplifying of blade of the present invention schematic diagram.
In figure: 1, handle of a knife; 2, blade; 3, chip area; 21, one-level blade;
22, secondary blade; 23, three grades of blades; 24, level Four blade; 25, Pyatyi blade; 211, blade tip; 221, fillet sword.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As Fig. 1, shown in Fig. 2, a kind of forming flat drill of the present invention, comprise integrated handle of a knife 1 and blade 2, handle of a knife 1 is cylindrical staight shank, and blade 2 is flat, double-sided symmetrical design, is provided with cambered surface chip area 3 between handle of a knife 1 and blade 2, and handle of a knife 1 and blade 2 are coaxial setting.
Wherein, blade 2 comprises the one-level blade 21 that sets gradually, secondary blade 22, three grades of blades 23, level Four blade 24 and Pyatyi blades 25, and its width increases step by step, in production process, is all formed in one.One-level blade 21 is arranged at foremost, Pyatyi blade 25 links with handle of a knife 1, and the knife edge of one-level blade 21, secondary blade 22, three grades of blades 23, level Four blade 24 and Pyatyi blades 25 is provided with cutting edge, blade polishing design, make the product glossiness that processes high, uniformity is high.One-level blade 21 tops are also provided with a blade tip 211, and blade tip 211 edges are also provided with cutting edge, and meanwhile, preferably, the blade tip angle of blade tip 211 is 120 °.Between secondary blade 22 and three grades of blades 23, be provided with fillet sword 221, preferably, fillet sword 221 is arc interface, and secondary blade 22 and three grades of blade junctions and vertical direction angle a are 12 °.
Secondly, chip area 3 is arranged at Pyatyi blade 25 and handle of a knife 1 junction, and with cambered surface transition, so, has strengthened the area of chip removal, and smear metal is more easily discharged in process.
Meanwhile, the junction of one-level blade 21 and secondary blade 22 at right angles arranges.The junction of three grades of blades 23 and level Four blade 24 at right angles arranges.The junction of level Four blade 24 and Pyatyi blade 25 at right angles arranges.
A kind of forming flat drill of the present invention, a plurality of blades that comprise one-level blade 21, secondary blade 22, three grades of blades 23, level Four blade 24 and Pyatyi blades 25, rational in infrastructure, strengthened the intensity of cutter, forming hole one-shot forming that can be to labyrinth in process, can effectively improve working (machining) efficiency, and improve the uniformity of converted products.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
