Abstract
The present invention relates to the numerical control ball blasting method of the yielding disk-like accessory of a kind of thin-walled, by special shot-peening fixture, realize fixture and install firmly in whole process, meanwhile, the installation accuracy while being controlled at clamping, makes the shot blasting effect of part good. Adopt both sides point to be carried out to the operation of shot-peening, the nozzle speed of service is identical, has ensured part stress equalization in whole shot-peening process, does not produce residual stress after shot-peening, and part deformation is little, can meet the indices of the yielding disk-like accessory shot-peening of thin-walled.
Description
Technical field
The present invention relates to a kind of ball blasting method, the numerical control spray of the yielding disk-like accessory of especially a kind of thin-walledBall method.
Background technology
At present the shot-blast process of general part is as follows: first use test piece determine the parameter of shot-peening (pressure,Shot-peening time, shot-peening distance), then part is lain on workbench, the end face that needs shot-peening of part is enteredRow bead. And for the shot-peening of the yielding disk-like accessory of thin-walled, after shot-peening part end face buckling deformation large,Part flatness is often overproof, and easily produces residual stress distortion after shot-peening, and the flatness of part is overproof tightHeavy, cannot meet the instructions for use of part.
Summary of the invention
The object of this invention is to provide the blasting technology of the yielding disk-like accessory of a kind of thin-walled, can realize suchPart meets all technical requirements such as flatness after shot-peening.
Concrete technical scheme of the present invention is:
(1) use with the test piece of shot-peening part same material and test, determine shot-peening parameter;
(2) processing parts, makes part lateral plane degree and end face beating in acceptability limit to inner bore of part;
(3) make special shot-peening fixture, fixture locating shaft is not more than beating of two ends center hole0.005mm, the magnitude of interference of fixture and inner bore of part is within the scope of 0.01～0.03mm;
(4) after Cleaning of Parts is clean, be arranged on fixture, then by fixture and part together clamping in numerical controlCompressed air shotblasting machine two top on;
(5) inspection part end face is beated and is not more than 0.01mm;
(6) parameter adjustment lathe numerical programming program during by processing test piece;
(7) start numerical control compressed air shotblasting machine, follow procedure rotation is top, two nozzles simultaneously along part radially to zeroPart carries out shot-peening, and the shot-peening position of two nozzles is with respect to part symmetry, and the speed of service is identical;
(8), after shot-peening finishes, inspection part benchmark is beated in 0,01mm;
(9) dismounting part final inspection.
The present invention adopts special shot-peening fixture, and described fixture locating shaft is little to beating of two ends center holeIn 0.005mm, the magnitude of interference of fixture and inner bore of part, within the scope of 0.01～0.03mm, is realized fixture wholeIndividual process is installed firmly, and meanwhile, the installation accuracy while being controlled at clamping, makes the shot blasting effect of part good. AdoptThe operation of with both sides, point being carried out shot-peening, the nozzle speed of service is identical, has ensured that part is in whole shot-peening processMiddle stress equalization, does not produce residual stress after shot-peening, part deformation is little, can meet indices.
Brief description of the drawings
Fig. 1 is ball blasting method schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, whole shot-peening step is as follows:
(1) use with the test piece of shot-peening part 3 same materials and test, determine shot-peening parameter;
(2) processing parts 3, makes part 3 lateral plane degree and end face beating at qualified model to inner bore of partIn enclosing;
(3) make special shot-peening fixture 1, fixture 1 locating shaft is not more than beating of two ends center hole0.005mm, the magnitude of interference of fixture 1 and part 3 endoporus is within the scope of 0.01～0.03mm;
(4) be arranged on fixture 1 after part 3 is cleaned up, then fixture 1 and part 3 filled togetherBe clipped in numerical control compressed air shotblasting machine two top on;
(5) check that part 3 end face run-outs are not more than 0.01mm;
(6) parameter adjustment lathe numerical programming program during by processing test piece;
(7) start numerical control compressed air shotblasting machine, follow procedure rotation is top, two nozzles 2 radially right along part simultaneouslyPart 3 carries out shot-peening, and the shot-peening position of two nozzles 1 is with respect to part 3 symmetries, and the speed of service is identical;
(8), after shot-peening finishes, inspection part 3 benchmark are beated in 0.01mm;
(9) dismounting part 3 final inspection.
