Abstract
Cylinder blank inwall becomes arc machining process and relates to domestic rolling stock spinning checking cylinder blank manufacture field, and the method comprises the steps: to be arranged on C630 lathe cylinder blank；Use the face of cylinder and the mid portion of bottom surface of hard alloy mechanically-clamped turning tool processing cylinder blank inwall；Utilize the molding cutter that corner radius is R1, according to processing request, the transition position circular arc L1 that radius is R1 between the processing cylinder blank inwall face of cylinder and inner bottom surface；Utilizing and manual roll out transition arc L2 that radius is R2 and the transition arc L3 that radius is R3 respectively, transition position circular arc L1, transition arc L2, transition arc L3 three are sequentially connected with；The radius R3 ＞ R2 ＞ R1 of above-mentioned three sections of circular arcs, and R1 is equal with core arc radius.The present invention is in the course of processing, and at the inwall face of cylinder and cylinder body bottom surface transition position, using radius is tri-sections of arc transition of R1, R2, R3, thus can ensure preferably to coincide with spinning mandrel bottom cylinder blank, it is ensured that the crudy of spinning part.
Description
Technical field
The present invention relates to domestic rolling stock spinning checking cylinder blank processing technique field, be specifically related to one
Cylinder blank inwall becomes arc machining process.
Background technology
Rolling stock spinning seal type brake cylinder cylinder body all uses stamping forming blank, through spinning, oral area
Machining aftershaping.Domestic rolling stock spinning checking cylinder blank, in addition to my company, all uses cold stamping
Blank produces, and blank inner and outer surfaces is not processed, direct rotary press modelling.But use cold stamping shaped blank,
Owing to sheet material its own face is through roll forming, surface is rougher, after spinning, and inside surface roughness one
As between Ra0.6～Ra1.25, it is difficult to fully meet the requirement being typically designed drawing Ra0.8.
Inside surface roughness in order to overcome cold stamping blank to exist can not meet the defect that design requires, I am public
Department uses heat stamping and shaping cylinder blank, but cylinder blank is in spinning process, due to inboard wall of cylinder block circle
Cylinder and cylinder body bottom surface transition position have crest line or step, and causing can not be fine with spinning mandrel bottom cylinder blank
Coincide, and then cause spinning part off quality.
Summary of the invention
Rib is there is through the spinning rear-bank rotor housing inwall face of cylinder with inner bottom surface transition position in order to solve drop stamping cylinder blank
Line or step, cause the technical problem that cylinder body spinning is off quality, in the present invention provides a kind of cylinder blank
Wall becomes arc machining process.
It is as follows that the present invention solves the technical scheme that technical problem taked:
Cylinder blank inwall becomes arc machining process, comprises the steps:
The first step, cylinder blank is arranged on C630 lathe；
Second step, the face of cylinder using hard alloy mechanically-clamped turning tool processing cylinder blank inwall and the centre of bottom surface
Part；
3rd step, utilize the molding cutter that corner radius is R1, according to processing request, processing cylinder chaeta
Radius between the base inwall face of cylinder and inner bottom surface is the transition position circular arc L1 of R1；
4th step, utilize and manual roll out transition arc L2 that radius is R2 and the transition that radius is R3 respectively
Circular arc L3, transition position circular arc L1, transition arc L2, transition arc L3 three are sequentially connected with；
The radius R3 ＞ R2 ＞ R1 of above-mentioned three sections of circular arcs, and R1 is equal with core arc radius.
The invention has the beneficial effects as follows: the method is in the course of processing, in the inwall face of cylinder and cylinder body bottom surface mistake
The place of crossing uses radius to be respectively three sections of arc transition of R1, R2, R3, thus can ensure bottom cylinder blank
Preferably it coincide with spinning mandrel, it is ensured that the crudy of spinning part.After using this method processing, cylinder body hair
Base inside surface roughness is up to below Ra12.5, through spinning, inner surface of cylinder block roughness up to Ra0.3～
Ra0.5, fully meets the requirement of design drawing Ra0.8.
Accompanying drawing explanation
Fig. 1 is the principle schematic that cylinder blank inwall of the present invention becomes arc machining process.
Detailed description of the invention
With embodiment, the present invention is described in further details below in conjunction with the accompanying drawings.
After drop stamping blank molding, concordance is bad, it is impossible to be processed with numerically controlled lathe, so only
Engine lathe can be utilized to be processed.
As it is shown in figure 1, cylinder blank inwall of the present invention change arc machining process is in the course of processing, first
Cylinder blank is arranged on C630 engine lathe；Then ordinary rigid alloy mechanical clamped cutting tool, processing cylinder are used
The face of cylinder of chaeta base inwall and the mid portion of bottom surface；Recycling corner radius is the one-tenth of R1=13mm
Type cutter, according to technology parameter request, rotating speed is 200～300r/min, the amount of feeding
30～40mm/min, the mistake that radius is R1=13mm between the processing cylinder blank inwall face of cylinder and inner bottom surface
Cross place circular arc L1；Saddle and middle carriage is the most manually utilized to roll out the mistake that radius is R2=17mm respectively by hand
Cross circular arc L2 and transition arc L3 that radius is R3=20mm.After above-mentioned processing, bottom cylinder blank
Can well coincide with the spinning mandrel that arc radius is R=13mm, then through spinning, inner surface of cylinder block is thick
Rugosity, up to Ra0.4, fully meets the requirement of design drawing.
