Abstract
The utility model discloses a formed milling tool for machining holes, belongs to a metal cutting tool and aims to provide a formed milling tool capable of saving cutting tool materials. The formed milling tool consists of a tool handle, a tool body integrated with the tool handle and a cutting part which is fixed on the tool body, wherein the cutting part consists of a plurality of chamfer facing blades (3) uniformly distributed on the tool body (2) and hole expansion blades (4) which are positioned below the chamfer facing blades (3) and are uniformly distributed on the tool body (2). By adoption of the structure, when a chamfer facing blade (3) or a hole expansion blade (4) is abraded or damaged, only the corresponding blade instead of the whole blade is needed to be replaced, so that the cutting tool materials are effectively saved, and the manufacturing cost is reduced. Besides, the tool is a metal-cutting formed tool.
Description
Technical field
The utility model relates to a kind of profile milling cutter, relates in particular to a kind of hole machine-shaping milling cutter.
Background technology:As everyone knows, the cutter hub that all is connected as a single entity by handle of a knife, with this handle of a knife of hole machine-shaping milling cutter, the cutting portion that is fixed on this cutter hub constitute.At present, one or a few shaping blades that constitutes cutting portion is generally monolithic construction, in case certain part wearing and tearing or damage of shaping blades then must be changed the monoblock blade, causes the cutter material waste.
Summary of the invention:In order to overcome the defective that exists in the prior art, the utility model aims to provide a kind of hole machine-shaping milling cutter of practicing thrift cutter material.
To achieve these goals, the utility model adopts following technical scheme: the cutter hub that it is connected as a single entity by handle of a knife, with this handle of a knife, the cutting portion that is fixed on this cutter hub constitute; Said cutting portion is by being evenly distributed on the flat blade of polylith chamfering ream on the cutter hub and being positioned at each chamfering ream flat blade below and the reaming blade that is evenly distributed on the cutter hub constitutes.
Compare with prior art; The utility model is owing to adopted technique scheme; Originally the monoblock type shaping blades that constituted cutting portion has been changed into the split-type structural that constitutes by the flat blade of chamfering ream and reaming blade two parts; So, only need the corresponding blade of replacing to get final product, and needn't the monoblock blade be changed when the flat blade of chamfering ream or reaming blade appearance wearing and tearing or damage; Practice thrift cutter material effectively, reduced processing cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of workpiece to be processed.
Among the figure: handle of a knife 1 cutter hub 2 chamfering reams are put down blade 3 reaming blades 4 workpiece 5
The specific embodiment:Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
In Fig. 1～2, cutter hub 2 is fixed on the handle of a knife 1 and is connected as a single entity with it, on cutter hub 2, is provided with cutting portion; This cutting portion is made up of four reaming blades 4 that are evenly distributed on the flat blade 3 of four chamfering reams on the cutter hub 2 and be positioned at flat blade 3 belows of each chamfering ream and be evenly distributed on cutter hub 2 correspondence positions.Wherein, the flat blade 3 of chamfering ream is mainly used in the end face, counterbore of the flat workpiece 5 of ream and chamfering is carried out in the aperture of this counterbore, and the bottom outlet that reaming blade 4 is mainly used in workpiece 5 carries out reaming processing.
Claims (1)
