In, milling cutter is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece etc. on milling machine, at present, in machining
, it is necessary to carry out follow-up such as drilling operating, usual use will be milled in industry generally after the completion of Milling Process operation in industry
Workpiece depart from fixture or remove facing cutter drill bit is installed, aforesaid operations can cause the complexity of manufacturing procedure, also increase
Piece count in process, while can also reduce the precision in parts machining process；In drilling operating, if
When processing the circular hole of multiple different-diameters, it is necessary to purchase the drill bit of branched different-diameter so that increase equipment investment, cause
Waste.
Utility model content
The purpose of this utility model be for complex procedures when being cut during the shape extrusion such as existing aluminium sheet, drilled,
Required workpiece is more；Circular hole for multiple different-diameters is, it is necessary to the problems such as drill bit substep of branched different-diameter is completed, there is provided one
Plant aluminium sheet and cut drilling one multistage cutting die, realization is cut, drilling once complete, without changing processing platform and processing work
Part；To the circular hole of the multiple different-diameters of processing, realize that two-stage is punched, keep hole surface smooth.
The purpose of this utility model can be realized by following technical proposal：
A kind of aluminium sheet cuts drilling one multistage cutting die, including the first cutter head, the second cutter head, the 3rd cutter head and cutting die
Main body, first cutter head, the second cutter head, the 3rd cutter head and cutting die main body are cylindrical structure, first cutter head and the
Two cutter head global formations are constituted, and first annular plane is formed between two-stage；Second cutter head and the 3rd cutter head global formation
Constitute, and the second planar annular is formed between two-stage；3rd cutter head is constituted with cutting die main body global formation, and between two-stage
Form the 3rd planar annular；Helical groove is provided with first cutter head, the second cutter head and the 3rd cutter head outer circumference surface, institute
Helical groove is stated to be incremented by from the downward groove bore of first bit tip.
In order to realize that a cutting die can drill the hole of different radii size, first tip radius are less than the second knife
Head radius, and radius ratio is 1:2~1:4.
In order to realize that a cutting die can drill the hole of different depth size, the cylinder of first cutter head it is tall and big in
The cylinder of the second cutter head is high, and height is than being 1:1.5~1:3.
First cutter head, the second cutter head, the 3rd cutter head and cutting die main body are metal integrated punching molding structure.
Each cutter head effect that the utility model aluminium sheet cuts drilling one multistage cutting die is respectively：First cutter head is used
In small-bore through hole Drilling operation；Second cutter head is used for the larger countersunk hole processing of bore；3rd cutter head is used
In the Milling Process of aluminium sheet.
The utility model has advantages below and beneficial effect compared to existing technology：
1st, multi-knife-head integrative-structure is used in the utility model, simple structure is easy to use, realization is cut, drilling operating
It is disposable to complete, without changing processing platform and processing workpiece, cutter need not be changed in process, it is right to save again
The trouble of knife, operationally reduces the complexity of manufacturing procedure, reduces the piece count in process, processing efficiency
It is high；
2nd, it is made up of the first cutter head and the second cutter head global formation, to the circular hole of the multiple different-diameters of processing, realizes two
Level punching, keeps hole surface smooth, is effective to ensure that concentricity and perpendicularity, drastically increases parts machining process
In precision；
The 3rd, helical groove be set on the multistage cutting die outer circumference surface of integrative-structure, and helical groove is from the first bit tip
Downward groove bore is incremented by, and is so designed that chip removal helical groove, rational in infrastructure, cut in process, drilling efficiency it is high.
