Muaj ob hom cua sov calibration ntawm titanium pas nrig qhov chaw: kub sib sau thiab calibration nyob rau hauv ob txheej txheem, tsim nyob rau hauv ib lub sij hawm; preforming thiab ces kub calibration. Lub tom kawg yog muab lub preform rau ntawm lub rhuab pwm, preheat nws mus rau ib tug tshwj xeeb kub, tswj nws rau ib tug tej lub sij hawm nyob rau hauv lub siab, ua ib tug thib ob txoj kev los yog kub xovxwm calibration, thiab ces tshem tawm ib feem.
Kev kho cua sov feem ntau yog siv los txo qhov ua yuam kev los yog distortions ntawm preforms ua los ntawm lwm cov txheej txheem tsim thiab txhim kho ib feem zoo. Kev kho cua sov tuaj yeem txo lub kaum sab xis thiab qhov loj me ntawm qhov sib txawv ntawm titanium pas nrig, cov duab sib txawv, khoov vojvoog deviations, ripples ntawm cov npoo npoo, wrinkles (tshwj tsis yog cov wrinkles tuag) thiab distortions tsim, nrog rau lub warping lossis agitation ntawm lub vev xaib, thiab lwm yam, kom tau txais qhov chaw uas ua tau raws li qhov kawg profile yuav tsum tau thiab muaj peev xwm ua tau zoo.
Lub hauv paus txheej txheem ntawm thermal calibration:
1. Txhim kho cov pwm ntawm cov xovxwm kub thiab preheat cov pwm nyob rau hauv lub qhov cub cua sov;
2. Ua kom sov cov pwm rau qhov ntsuas kub thiab ua kom qhov kub thiab txias;
3. Txhim kho cov ntaub plaub lossis cov khoom ua ntej ntawm cov pwm thiab ua kom sov rau qhov ntsuas kub;
4. Tom qab kaw cov pwm, siv lub siab txaus thiab tswj nws rau ib lub sijhawm kom tau txais cov khoom raws li qhov yuav tsum tau ua;
5. Tshem tawm ib feem ntawm cov pwm thiab cia nws txias sib npaug mus rau chav sov.
Nws yog ib qho tseem ceeb kom paub meej tias cov khoom tshem tawm txias sib npaug. Yog hais tias qhov zoo-calibrated ib feem muaj cov residual kev nyuaj siab tshwm sim los ntawm ib tug loj kub txawv thaum lub sij hawm txias, ib feem yuav warp. Ua li no, cov khoom tuaj yeem raug dai rau ntawm qhov tshwj xeeb txias racks lossis txav mus rau asbestos mats kom txias. Yog tias tsim nyog, rau qee qhov chaw, lub phaj cua sov tsis sib xws lossis calibration fixture tuaj yeem siv los ua kom txias rau ntawm qhov qeeb qeeb lossis hauv lub xeev clamped. Vim tias cadmium (Cd), tin (Sn), lead (Pb) thiab zinc (Zn)-raws li alloys ua raws li titanium rods ntawm qhov kub thiab txias, lawv yuav ua rau titanium ua nkig (xws li "cadmium embrittlement"), thiab cov khoom. yuav puas. Kev tawg lossis kev puas tsuaj tag yuav tshwm sim thaum raug quab yuam. Yog li ntawd, nws yog txwv tsis pub siv cov hlau lead lossis cov hlau lead-raws li cov hlau lead hauv cov pwm lossis cov khoom siv uas tuaj yeem tiv nrog titanium. Kev siv cov zinc los yog tin-raws li alloy pwm los yog fixtures thiab zinc-plated, tin los yog cadmium pwm, fixtures los yog ib ntus fasteners yog txwv tsis pub thaum hlau tsis raug tshem tawm raws li tau teev tseg.
Thaum lub sij hawm kub calibration, lub workpiece, pwm, kev khiav hauj lwm cov cuab yeej, thiab lwm yam yuav tsum tau ceev kom huv si thiab yuav tsum tsis txhob muaj av los yog tej yam khib nyiab.
