Description
Technical field
This utility model belongs to process tool field, relates to a kind of alloy cutter, is specifically related to a kind of contoured PCD milling cutter.
Background technology
Reamer is that one has one or more cutter tooth, in order to excise the rotary cutter of hole surface sheet metal.Reamer on ream workpiece drilling (or reaming) processing after hole, be primarily to improve hole machining accuracy, reduce the roughness on its surface, be the polish for hole and semi-finished cutter, allowance is generally only small.PCD cutter is polycrystal diamond cutter (belonging to the one of superhard cutter), and it has the characteristics such as hardness height, comprcssive strength height, heat conductivity and wearability are good, can obtain significantly high machining accuracy and working (machining) efficiency in high-speed cutting.When the groove with particular/special requirement is processed, existing PCD cutting blade often has unicity, it is impossible to meet one-shot forming demand, often repeatedly to polish, add processing step, waste manpower and materials.
Summary of the invention
This utility model is in order that overcome the deficiencies in the prior art and provide a kind of contoured PCD milling cutter.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of contoured PCD milling cutter, and it includes:
Handle of a knife；
Cutter hub, described cutter hub includes the connecting portion being integrally formed at described handle of a knife end and the support portion being integrally formed at described connecting portion the other end, described support portion side face is sequentially provided with multiple first blade, multiple second blade, multiple 3rd blade and multiple 4th blade from inside to outside, described first blade, the second blade, the 3rd blade and the 4th blade stagger setting, and described support portion side face is additionally provided with groove corresponding with described first blade, the second blade, the 3rd blade and the 4th blade respectively and Cooling Holes.
Optimally, the size of described first blade, the second blade, the 3rd blade and the 4th blade is sequentially reduced.
Optimally, described handle of a knife includes being integrally formed at the holding section of described cutter hub end and being integrally formed at the fixed part of end, described holding section, and described holding section side face offers draw-in groove and the card ear extended to described fixed part direction.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that the contoured PCD milling cutter of this utility model, by setting gradually multiple first blade, multiple second blade, multiple 3rd blade and multiple 4th blade from inside to outside at the support portion side face of cutter hub, they stagger and arrange and corresponding with groove and Cooling Holes, so with multiple blade, workpiece profile can be processed successively, its one-shot forming can be made, improve working (machining) efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model preferred embodiment is described in detail:
Contoured PCD milling cutter as shown in Figure 1, mainly includes cutter hub 1 and handle of a knife 2.
Wherein, cutter hub 1 includes the blade (first blade the 121, second blade 122, the 3rd blade 123 and the 4th blade 124 etc.) of connecting portion 11, support portion 12 and multiple different size；One end of connecting portion 11 is connected with the end one of handle of a knife 2, and its other end is then connected with support portion 12 one.The side face of support portion 12 is made up of the first anchor ring from inside to outside set gradually, the second anchor ring, the 3rd anchor ring and the 4th anchor ring, first anchor ring, the second anchor ring, the 3rd anchor ring and the 4th anchor ring are separately installed with multiple first blade 121, multiple second blade 122, multiple 3rd blade 123 and multiple 4th blade 124, these blades are spacedly distributed on respective anchor ring, and setting of staggering.The side face of support portion 12 is additionally provided with groove 126 corresponding with first blade the 121, second blade the 122, the 3rd blade 123 and the 4th blade 124 respectively, it is provided with Cooling Holes 125 in corresponding groove 126, so with multiple blade, workpiece profile can be processed successively, its one-shot forming can be made, improve working (machining) efficiency.
In the present embodiment, the size of first blade the 121, second blade the 122, the 3rd blade 123 and the 4th blade 124 is sequentially reduced, such that it is able to workpiece profile is carried out polish in various degree.Handle of a knife 2 includes the holding section 21 being integrally formed at cutter hub 1 end and the fixed part 22 being integrally formed at end, holding section 21, holding section 21 side face offers draw-in groove 211 and the card ear 212 extended to fixed part 22 direction, for being connected with Digit Control Machine Tool or machining center.
Above-described embodiment is only for illustrating technology of the present utility model design and feature; its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this; protection domain of the present utility model can not be limited with this; all equivalences made according to this utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
