Ua rau lub thoob hniav deformation ntawm excavator

1. Warping deformation: warping deformation tshwm sim ntawm ob qho tag nrho los yog ib qho kawg lossis txawm tias lub peripheral ntug thiab qhov kawg ntawm cov casting tom qab xuab zeb tu, uas ua rau nruab nrab ntawm cov casting concave, uas ua rau cov khoom tsis sib xws. Daim ntawv deformation no hu ua warping deformation. Cov laj thawj yog: thaum lub casting txias, lub thickness los yog tuab ntawm casting yog tsis sib npaug, thiab muaj qhov kub thiab txias sib txawv, ua rau cov cua txias sib txawv ntawm ntau qhov chaw ntawm cov casting, ua rau cov yas deformation tsis sib xws, ua rau warpage deformation.
2. Flaring deformation: qhov laj thawj yog vim li cas cov xuab zeb core lossis xuab zeb pwm ntawm qhov qhib loj cuam tshuam lub shrinkage ntawm casting, ua rau cov yas deformation ntawm cov qauv dawb ntawm qhov qhib casting, uas ua rau flaring deformation defects.
3. Micro self deformation: nyob rau hauv cov ntaub ntawv alloy, grey cam khwb cia hlau Z yog nquag mus rau micro self deformation. Cov residual kev nyuaj siab ntawm grey cam khwb cia hlau tom qab tshem tawm xuab zeb yog tsuas yog residual thermal stress. Residual stress tsis yog tsuas yog lub ntsiab ua rau casting txias tawg, casting deformation thiab lwm yam tsis xws luag, tab sis kuj yog lub ntsiab ua rau micro self deformation.
