Description
Technical field
The utility model is related to a kind of processing high-temperature alloy blades hard alloy bulb milling cutters, belong to milling cutter processing technology neck
Domain.
Background technology
Since high temperature alloy has high intensity, high tenacity, high thermal stability, heat-resistant anti-fatigue and lower thermal conductivity etc. a series of excellent
Point, thus it is widely used in the fields such as aerospace, but simultaneously but also the machining of this kind of alloy becomes difficult.This
Outside, processing high temperature alloy is easily formed built-up edge, generates processing hardening and rebound phenomenon so that and cutting environment is complicated and changeable, this
A little factors can all cause cutting resistance to increase, and cutting temperature increases, tool wear and failure aggravation, namely to the structure shape of cutter
Formula and geometric parameter propose more stringent requirement.
Processing for high-temperature alloy blades, the main bulb cutting edge portion using cutter carry out milling, thus to bulb
The appearance of part cutting edge and bulb is considered to be worth doing and chip removal is more demanding, however bulb anterior angle, bulb relief angle and bulb cutting edge blunt circle half
Diameter is the key that influence bulb cutting edge geometric parameter again, these parameters it is excessive or it is too small be all unfavorable for cutting, such as bulb anterior angle and
When relief angle is excessive or bulb cutting edge blunt round radius is too small, bulb cutting edge is although sharp, but cutting edge strength is relatively low, and milling high temperature closes
It is easy to generate that micro- to collapse and peel off and can accelerate tool wear, bulb chip pocket be to influence cutting when the larger material of this kind of hardness of gold
The important feature for holding bits and chip removal in the process, when chip space is smaller, easy Integrated Chip and stifled bits are unfavorable for distributing cutting heat, in addition,
Helical angle is also to influence the major parameter of such cutter, and therefore, the structure and parameter design of cutter will reasonable and item matching ability
Meet high-efficient cutting.
Utility model content
The purpose of the utility model is to provide it is a kind of it is simple in structure, intensity is high, the processing high temperature alloy of excellent cutting performance
Blade hard alloy bulb milling cutter, to overcome deficiency in the prior art.
The technical solution of the utility model：A kind of processing high-temperature alloy blades hard alloy bulb milling cutter, including handle of a knife with
And the spiral part being connected as one with handle of a knife and bulb part, helical flute, spiral row are evenly equipped on the spiral part
The helical angle for considering slot to be worth doing is 40~45 °；It is evenly equipped with bulb blade on the bulb part, bulb is offered between helical form blade
Chip pocket on the bulb blade is made of bulb anterior angle, bulb relief angle and bulb cutting edge blunt round radius.
Further, the bulb anterior angle is 6~8 °, and bulb relief angle is 8~12 °.
Further, the bulb cutting edge blunt round radius is 0.005~0.008mm.
Further, the bulb chip pocket is formed by forming grinding wheel grinding.
Due to the adoption of the above technical scheme, the utility model has the advantage of：The utility model optimize bulb anterior angle, after
Angle, cutting edge blunt round radius and helical angle geometric parameter, the cutting edge of a knife or a sword of bulb cutting edge is enhanced while ensureing bulb cutting edge strength
Profit reduces cutting resistance, and bulb chip pocket is formed by forming grinding wheel grinding, it is ensured that holds bits in cutting process
With chip removal and the intensity of bulb part, cutting-tool's used life and product processing quality are improved.
