Abstract
The invention discloses a kind of seal rubber part turnings, the dedicated monoblock type lathe tool in end face, through hole K, the anterior angle that main cutting edge is 17 °, 7 °~8 ° of rear corner structure are provided at cutter head and between main cutting edge and end cutting edge, the anterior angle that end cutting edge is 17 °, 7 °~8 ° of rear corner structure.Present invention improves the radiating conditions of lathe tool, reduce influence and abrasion of the cutting heat to Part Surface Roughness in processing, the durability of lathe tool are improved, to ensure that the quality of part.
Description
Technical field
The present invention relates to one kind, aerodynamic testing equipment nonstandard rubber seal outer circle, end face hydraulic for aeronautical product
Dedicated monoblock type lathe tool.
Background technique
Currently, engine nozzle, spray boom, casing class test fixture are needed using a large amount of rubber hermetic devices,
There are three classes in source:
(1) standard purchase price is pressed；
(2) specialized factory's casting Special-shaped seal components；
(3) itself processing rotation class small-sized sealing part is based oneself upon.
Being considered based on various aspects, itself processing rotation class small-sized sealing part is based oneself upon in selection, because of the poor radiation of rubber material,
Rigidity is insufficient simultaneously to have stronger toughness, and the heat for the generation that makes to rub in process concentrates on lathe tool cutter hub and material, causes
Design requirement is not achieved in general lathe tool abrasion, the surface roughness and dimensional accuracy of sealing element.It therefore need to be special for rubber material
Property, and general lathe cutter structure is analyzed, design specialized lathe tool.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of envelope rubber parts turning, the dedicated monoblock type lathe tool in end face, needle
To rubber material characteristic, design specialized lathe tool improves the radiating condition of lathe tool, and it is coarse to piece surface to reduce cutting heat in processing
The influence and abrasion of degree, improve the durability of lathe tool, to guarantee the quality of part.
In order to solve the above-mentioned technical problem, the present invention is realized by following technical method:
A kind of seal rubber part turning, the dedicated monoblock type lathe tool in end face at cutter head and are located at main cutting edge and secondary cutting
It is provided with through hole K between sword, the anterior angle that main cutting edge is 17 °, 7 °~8 ° of rear corner structure, the anterior angle that end cutting edge is 17 °, 7 °
~8 ° of rear corner structure.
Cutter hub material selection T12A, and Rockwell hardness is HRC60~64.
The level cross-sectionn of the through hole K is trapezoidal, and a trapezoidal waist is parallel to main cutting edge, and a bottom edge is parallel
In end cutting edge.
Rounded corner between the main cutting edge and end cutting edge, and radius is 0.2mm.
Angle between the main cutting edge and end cutting edge is 85 °.
The present invention improves in terms of following three:
(1) design increases the heat dissipation area of cutter hub, improves the radiating rate in process, smaller cutting heat is to processing
Unfavorable factor；
(2) anterior angle and relief angle for increasing cutter, improve the sharpness of cutting edge roundness, to reduce cutting resistance, improvement is cut
The deformation for cutting middle workpiece improves the dimensional accuracy and surface roughness of part；
(3) select T12A material be used as cutter hub material, forged, timeliness and quenching treatment, Rockwell hardness for HRC60~
64；
Compared with prior art, lathe cutter structure of the invention makes adding for the rotation class small-sized sealing part for basing oneself upon itself processing
Working medium amount is significantly improved, and effectively raises the surface roughness of workpiece, while cutting wear is improved 60
~70%, reduce tool sharpening number and time.
Detailed description of the invention
Fig. 1 is monoblock type lathe tool main view；
Fig. 2 is Fig. 1 top view；
Fig. 3 is main cutting edge anterior angle and relief angle schematic diagram (Section A-A in corresponding diagram 2)；
Fig. 4 is end cutting edge anterior angle and relief angle schematic diagram (section B-B in corresponding diagram 2).
Specific embodiment
1~4 couple of present invention is described in further details with reference to the accompanying drawing:
(1) whole tool special design is carried out by Fig. 1；
(2) it is hollowed out at " K " between main cutting edge and end cutting edge in Fig. 2, that is, opens through hole K, increase the surface of cutter hub
Product reduces influence of the cutting heat to workpiece accuracy in process to increase the heat dissipation area of cutter hub, improves work pieces process essence
Degree, and be conducive to chip material and excluded from cavity；
(3) by shown in Fig. 3 section A-A: the anterior angle of 17 ° of main cutting edge of design, 7 °~8 ° of rear corner structure increase cutter master
The sharpness of cutting edge, to improve the surface roughness of workpiece；
(4) by shown in Fig. 4 section B-B: the anterior angle of 17 ° of end cutting edge of design, 7 °~8 ° of rear corner structure increase cutter pair
The sharpness of cutting edge；
(5) cutter hub material selection T12A material is as cutter hub material, forged, timeliness and quenching treatment, Rockwell hardness
HRC60~64；
(6) size L, L1, L2, L3, L4, A, B, C, D can be determine according to actual needs in Fig. 1 and Fig. 2.
Claims (3)
