Yuav ua li cas kho cua sov Deformation hauv 3D Vuam Rooj

I. Mechanical Straightening: Tsim nyog rau me me mus rau nruab nrab cov phiaj xwm warping thiab khoov deformation.
Txoj kev no tiv thaiv kev deformation los ntawm kev siv lub zog sab nraud yam tsis hloov cov khoom siv, thiab nws cuam tshuam rau kev ua haujlwm qis dua. Rau planar warping: Khaws lub workpiece kom ruaj khov rau ntawm lub txaj ntawm lub xovxwm loj; Tom qab nrhiav qhov chaw tsa (convex), maj mam siv lub txee-siab rau qhov chaw ntawd, tuav lub siab rau 10–15 feeb, thiab tom qab ntawd tso tawm. Re- ntsuas flatness thiab incrementally kho lub siab kom txog rau thaum qhov yuav tsum tau precision tiav. Rau me me deformations, yuav siv tau ib txhais tes rauj thiab tiaj tus anvil; maj mam hammering thiab dov qhov tsa qhov chaw stretches cov khoom los kho cov duab. Txhawm rau khoov lossis angular deformation: Siv lub tshuab ncaj nraim lossis hydraulic jack siv lub zog txuas mus rau sab convex ntawm qhov khoov. Kho lub siab raws li qhov deformation, tuav lub siab, rov- ntsuas, thiab maj mam kho qhov chaw kom nyob rau hauv tus qauv tolerances.
Lus Cim: Mechanical straightening yoojyim tom qab qee qhov kev ntxhov siab sab hauv. Nws raug nquahu kom ua qhov qis - qhov kub thiab txias - cov txheej txheem tempering nyem tom qab ncaj nraim -soaking ntawm 300℃rau 30 feeb tom qab los ntawm qhov cub txias- los tiv thaiv kev deformation yav tom ntej.

II. Flame Straightening: Haum rau nruab nrab mus rau hnyav deformation; muaj feem xyuam rau ob qho tib si cam khwb cia hlau thiab steel qauv.
Txoj kev no siv cov thermal expansion thiab contraction zog ntawm hlau, counteracting uas twb muaj lawm deformation los ntawm localized cua sov thiab tom qab txias txias - induced shrinkage. Nws yog cov txheej txheem ncaj tshaj plaws hauv kev tsim khoom, nrog rau kev ua haujlwm tshwj xeeb kom haum rau hom deformation: Rau kev khoov lossis angular deformation, siv cov cua sov tawm mus rau sab convex, nruj me ntsis tswj qhov kub ntawm 600℃thiab 800 degree; ib txhij cua sov raws ob kab sib txuas yuav raug siv los tiv thaiv kev sib tw tshiab. Rau planar "wavy" deformation, siv qhov chaw cua sov ntawm yoj crests ua ke nrog lub teeb rauj; Qhov kub ntawm qhov chaw yuav tsum yog 50-90 hli (hloov raws li phaj thickness). Thaum qhov kub nce mus txog 600-700 degree, maj mam rauj rau qhov chaw sov; txias shrinkage yuav ces flatten nto. Rau flange angular deformation, siv longitudinal linear cua sov nyob rau sab nraud ntawm lub vuam; khaws qhov kub hauv qab 650℃thiab txwv qhov cua sov rau thaj tsam ntawm cov ntiv taw; tso cai rau ntuj txias dua li dej txias. Nco tseg: Nplaim taws ncaj yuav tsum muaj kev txawj ua haujlwm siab. Cam khwb cia hlau welding rooj yuav tsum tau tso cai kom txias maj mam tom qab tus txheej txheem; dej txias yog nruj me ntsis txwv tsis pub tiv thaiv cov khoom tawg. Kev tso cua sov tsis raug lossis qhov kub ntau dhau tuaj yeem ua rau deformation ntxiv; yog li ntawd, cov txheej txheem yuav tsum tau ua los ntawm cov kws tshaj lij.

III. Combined Straightening: Haum rau txoj kev nyuaj, hnyav deformation
Rau cov rooj vuam uas nthuav tawm qhov tseem ceeb deformation los yog cov geometries nyuaj, ib qho kev sib xyaw ua ke tau pom zoo: kev hloov kho thawj zaug ntawm kev kho tshuab ncaj nraim ua raws li kev nplua -tuning ntawm nplaim taws ncaj. Mechanical straightening kho qhov loj qhov sib txawv, thaum nplaim taws ncaj qha chaw nyob hauv zos, me me distortions. Thaum ua tiav, qhov qis- qhov kub thiab txias- kev kho mob nyem yog siv los tshem tawm cov kev ntxhov siab vim thaum lub sijhawm ua kom ncaj, kom ntseeg tau ntev - lub sij hawm seem stability.

Yog hais tias qhov deformation ntau tshaj 0.1 hli ib 1,000 hli, rov qab precision mus rau qib uas tau txais yog ib qho nyuaj, thiab tus nqi ntawm straightening mus kom ze ntawm ib chav tsev tshiab; Nyob rau hauv tas li ntawd, kev hloov ncaj qha yog pom zoo.
