Description

The titanium pipe blank grinding machine that nuclear power station condenser is used
Technical field
The invention belongs to metal material surface processing machine technical field, be specifically related to the titanium pipe blank grinding machine that a kind of nuclear power station condenser is used.
Background technology
Because the specific strength of titanium is positioned at before the metal, and has the advantages that heat resistance is good, resistance to low temperature is excellent, the antidamping performance is strong, nonmagnetic and avirulence, decay resistance are stood out from one's fellows and toughness is desirable, so purposes is very extensive.
As the industry's knowledge of the reason, no matter be titanium pole or titanium pipe, because there is oxide layer in the surface, therefore needed before making target product figuring of surface, so-called reconditioning is by sand mill or claims sharpening machine that surface oxide layer is removed.In the reconditioning process, hold titanium pipe body by the workman, under the motion of the emery wheel (adopting resin wheel usually) of sand mill, the titanium pipe is low passed through from emery wheel, thereby the oxide layer of titanium tube-surface is removed.This reconditioning mode exists following shortcoming to be: the one, and working strength of workers is big, because not only will hold the titanium pipe reliably, and will help the rotation of titanium pipe and will follow advancing and advance (moving step) of titanium pipe; The 2nd, the quality of reconditioning is difficult to ensure, because the gait of march of titanium pipe is artificially controlled by the workman basically, workman's step moves excessive velocities then style of calligraphy characterized by hollow strokes phenomenon can occur, and so-called style of calligraphy characterized by hollow strokes phenomenon is Lou mill, crossing had then both influenced efficient slowly, can duplicate reconditioning again and caused the waste of material; The 3rd, it is unified that the reconditioning effect is difficult to, because both there had been individual difference in different workmans, has the experience difference again, and therefore the reconditioning effect of the titanium pipe body that goes out of different workman's reconditionings can't be consistent; The 4th, in the reconditioning process, worn trifle in the world fills the air on titanium pipe body, has both influenced the working environment at reconditioning scene, has the anxiety that undermines workers ' health again.
The applicant thinks, the basic reason of above-mentioned shortcoming is to lack due to the sharpening machine rational in infrastructure, because the figuring of surface quality requirement of the titanium pipe that nuclear power station condenser is used is harsh, the diameter that adds the titanium pipe is relatively large, if therefore still adopt the sand mill that widely uses in the prior art, so not only quality and efficient can't ensure, and workman's muscle power can't be tackled.The applicant has also carried out literature search for this reason, yet, owing in disclosed patent documentation and non-patent literature, there is no all corresponding techniques enlightenments that has, therefore, the applicant has made arduous exploration and practice, and technical scheme described below produces under this prospect.
