Vertical ultra-thin-wall magnadure milling cutter
The utility model relates to a kind of milling cutter, and especially a kind of vertical ultra-thin-wall magnadure milling cutter belongs to the machining tool technical field.
Magnadure is as a kind of new material, because of its light weight, good characteristic that intensity is high, is widely used in aviation and personal electric product.But its processing of processing thin-walled die cavity especially is very difficult, main cause is a constituent material intensity height, cavity wall is thin and high, adopting cutter commonly used of the prior art to add easily shakes man-hour, produce resonance, machined surface precision and any surface finish are difficult to reach instructions for use, and working (machining) efficiency is also had a greatly reduced quality.
Therefore, how to design a kind of novel process tool, become the technical barrier that those skilled in the art need to be resolved hurrily to overcome above-mentioned defective.
The utility model content
The utility model aims to provide a kind of vertical ultra-thin-wall magnadure milling cutter, it has overcome above-mentioned deficiency by special structure design, eliminated vibration source and potential covibration, improved precision, efficient and the security of ultra-thin-wall magnadure processing, its technical scheme that adopts is as follows:
This vertical ultra-thin-wall magnadure milling cutter comprises: handle of a knife and the blade that is positioned at described handle of a knife end, wherein, described blade includes a plurality of all swords and corresponding with it helicla flute and α helical angle, described Zhou Ren is positioned at described spiral fluted top, forms described α helical angle between the two-edged limit of each all sword.
Preferably, described helicla flute is the backpitch groove.
Preferably, the angle of described α helical angle (4) is more than 30 °.
Compared with prior art, the utlity model has following advantage:
1, by backpitch incision design, eliminates vibration source by the press-down type cutting way;
2, prevent resonance by large helix angle design reducing side direction amplitude.
Description of drawings
Fig. 1: the structural representation of vertical ultra-thin-wall magnadure milling cutter of the present utility model.
Symbol description: 1, handle of a knife; 2, Zhou Ren; 3, helicla flute; 4, helical angle.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example:
An embodiment of the present utility model as shown in Figure 1, this vertical ultra-thin-wall magnadure milling cutter mainly comprises: handle of a knife 1 and the blade that is positioned at handle of a knife 1 end, wherein, blade includes a plurality of all swords 2 and corresponding with it helicla flute 3 and α helical angle 4, all swords 2 are positioned at the top of helicla flute 3, form α helical angle 4 between the two-edged limit of each all sword 2.
Helicla flute 3 is the backpitch groove, and the angle of α helical angle 4 is bigger, more than 30 °.
The operation principle of this vertical ultra-thin-wall magnadure milling cutter of following brief analysis: when processing ultra-thin-wall magnadure, the processing of backpitch groove, press-down type processing according to the mechanical analysis design have been eliminated the common process side direction operating force opposite with chucking power, thereby have effectively been eliminated vibration source; The large helix angle design of blade uniqueness can accomplish that cutting edge roundness is sharp and do not have resonance, and it is brisk to add the cutting in man-hour, thereby improves working (machining) efficiency greatly, and has guaranteed the surface smoothness of product to be processed.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
