Description

A cutting edge inequality divides milling cutter for processing compressor vortex
Technical Field
The utility model relates to a machining technology field, more specifically say, it relates to a cutting edge inequality divides milling cutter for processing compressor vortex.
Background
The milling cutter is a rotary cutter which is used for milling and provided with one or more cutter teeth, and the cutter teeth cut off the allowance of a workpiece intermittently in sequence during working; the milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine.
When the existing end milling cutter is used for machining parts such as compressor scroll, the following defects are mainly existed: 1. the cutting edges of the traditional end mill are evenly distributed, continuous harmonic vibration can be generated during processing, and particularly when the same (vortex type) processing feeding mode is kept for a long time, the processing quality of the surface of a part is reduced due to long-time processing, so that the workpiece is repaired, and even the workpiece can be scrapped; 2. the strength of the cutter is not enough, and the processing life is greatly influenced; 3. when some deeper slotted holes are processed, burrs are easily left at the opening of the slotted hole, secondary processing is needed, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a cutting edge inequality divides milling cutter for processing compressor vortex, it has can effectively reduce the vibration, promotes cutter intensity, mills the effect
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a cutting edge does not divide milling cutter equally for processing compressor vortex, includes handle of a knife, cutter body, week sword and helicla flute, its characterized in that: the cutter body includes five unequally divided end blades, include the tooth's socket between the end blade, five adjacent end blade is 67 along the central axis direction of cutter body to the plane of projection of cutter body bottom surface and the shared angle of an adjacent tooth's socket in proper order, 77, 72, 67, 77.
Preferably, the bottom edge comprises a wiper edge, and the wiper edge is recessed by an angle of 0.5 °.
Preferably, a chamfer angle with an included angle of 45 degrees with the peripheral edge at the position is arranged at the connecting position of the peripheral edge and the cutter body, and the bottom line of the chamfer angle is perpendicular to the tangent line of the peripheral edge at the position.
Preferably, the spiral angle of the spiral groove is 30-40 degrees.
Preferably, the peripheral edge includes a peripheral edge rake angle and a peripheral edge relief angle, and the angles of the peripheral edge rake angle and the peripheral edge relief angle are 4 ° and 11 °, respectively.
Preferably, the diameters of the tool shank and the tool body are 12mm and 10mm respectively.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the five blades are not completely equally divided, so that the cutter is prevented from resonating with a product in the machining process, the reduction of the machining quality of the surface of a part caused by long-time machining is prevented, and the quality of a machined product is improved;
2. by arranging the bottom edge smoothing edge, the rigidity of the sharp corner of the cutter is increased, the inner concave angle of the smoothing edge is 0.5 degree, and the contact area of the bottom edge is increased, so that the finish degree of the bottom edge is increased;
3. the cutter external diameter D10 connects D12 handle of a knife, increases the cutter rigidity, and the department of meeting of circumference sword and cutter body is provided with 45 degrees chamfers, gets rid of hole exit burr, and a sword is multi-purpose.
Drawings
FIG. 1 is a schematic view of a tool;
fig. 2 is a schematic structural view of an unequal bottom edge.
In the figure: 1. a knife handle; 2. a cutter body; 21. a peripheral edge; 211. chamfering; 22. a helical groove; 23. a bottom edge; 24. a tooth socket; 231. and (4) smoothing the edge.
