Description
Technical field
The invention belongs to Milling Process field, the interior grid surface particularly to a kind of taper revolving body is high
Effect method for milling.
Background technology
Currently mainly use skeleton covering riveting, casting, chemical milling, melting welding, solid forging or
The technology such as agitating friction weldering manufacture large thin-wall taper rotary part.
Large cone revolving body manufacturing technology level with manufacture equipment capability propose renewal upgrading with low become
This manufacture requirements, the manufacture of large-scale unitary tapered revolving body is except structure light wt to be met, it is necessary to tool
Standby good comprehensive mechanical property, at present, in employing grid ribs, the large cone revolving body of shape curved surface is
Become a kind of structure type that product design is first-selected.The mode generally using rough forging+machining is entered
The interior shape grid that row manufacture, the large-scale grid ribs curved surface opening for large scale and inner mold space are the biggest
Muscle curved surface, mainly uses NC Milling mode to remove material surplus, and processing space is done with main shaft
The Mini-type Grid muscle curved surface related to, can process by the mode of chemistry milling, but chemistry milling environmental pollution is relatively
Greatly, not using, in NC Milling, grid surface becomes first-selected processing method.
Therefore, in Aerospace manufacturing industry, the processing for the interior grid surface of large cone revolving body is main
Use solid forging blank, carried out the manufacture of product by Milling Process.
The interior grid Machining of Curved Surface feature of taper revolving body has the following characteristics that
(1) the own diameter of taper revolving parts with interior grid surface is big, wall is thin, on periphery
Opening is many, the highest, rigidity is weak, is easily generated deformation；
(2) in taper revolving body, shape is made up of large-area interior grid surface, and material removal amount is very big,
Traditional diamond-making technique uses ball head knife processing curve, and working (machining) efficiency is low, and uses the processing of round nose cutter to deposit
The requirement of design is not reached in surface roughness；
(3) large-scale interior grid Machining of Curved Surface unit is latticed, and turning quantity is many, and cutter commutation is frequent,
At grid periphery corner's main shaft everywhere by greater impact, spindle vibration amplitude is big, easily causes and gnaws cutter；
(4) interior grid surface separation muscle is not of uniform size with curved surface difference in height.Height fall is big, adds man-hour
The cantilevered out amount of cutter is relatively big, and the tool diameter used during sidewall back chipping is less than normal, and cutter poor rigidity easily occurs
Cutter fractures, and it is impaired that cutter gnawed by part；
(5) material is removed and is concentrated mainly in Milling Process, and milling amount is relatively big, and there is heat in processing should
Power and cutting stress；
Interior grid surface is generally present in wall thickness and is less than 4mm, and diameter is more than Φ 900mm, is highly more than
In the large cone revolving body of 400mm.
The processing method of the interior grid surface of existing taper revolving body is as follows:
(1) after heat treatment step is arranged in rough turn inside and outside shape, before milling；
(2) work flow be divided into rough mill, finish-milling operation, use machining center milling inner cone curved surface mode
Carry out milling；
(3) interior grid Machining of Curved Surface is rough milled with round nose cutter, carries out curved surface finish-milling with ball head knife；
(4) sidewall back chipping uses ball head knife, the final mode using pincers worker polishing to carry out back chipping.
Big material removal area is not rough milled before heat treatment, after causing rough milling interior grid surface
Deformation is relatively big, and part, owing to deformation is beyond allowance, also needs to increase the in-process of internal stay correction
Hold；Not having artificial aging procedure arrangement between interior grid Surface Rough, finish-milling, the stress after rough milling does not fills
Subrelease is put, and during finish-milling, deformation amount controlling difficulty, directly influences this type of part wall thickness dimension precision；Milling
Cut processing capacity unreasonable distribution, cause when revising deformation, occurring that correcting margin is inadequate, part wall unevenness
Even, circularity is poor, it is impossible to ensure use requirement；Use rose cutter to be processed during finish-milling, add work efficiency
Rate is low, and the process-cycle is long；During sidewall back chipping due to cutter elongation relatively greatly, easily breaking, and tool changing
After again to cutter, error is big, the most relatively loses time；Interior grid surface corner rate controlled is undesirable,
Cutter phenomenon is gnawed in generation.
