Dab tsi yog cov yam ntxwv ntawm hluav taws xob cua sov raj hmoov noj thiab shrinking

Powder feeding (cov txheej txheem tseem ceeb thiab tseem ceeb)

1. Ntxuav cov txhob lo lo ntxhuav nrog cov roj av qib siab thiab tshuab ziab nrog cua compressed;

2. Tshaj tawm MgO hmoov rau hauv lub tais nrog lub thickness tsis pub tshaj 40mm thiab muab tso rau hauv qhov cub. Thaum nws yog ib qho tsim nyog yuav tsum tau hnav cov tub ntxhais magnesium, nws yuav tsum tau muab tso rau hauv qhov cub thiab ziab ntawm qhov kub ntawm 100 degree rau 1-3 teev kom qhuav tag. Nws yog qhov zoo tshaj rau ntxiv cov hmoov nrog kub;

3. Xyuas kom meej qhov ntev ntawm cov hlau lead tawm pas nrig rau hauv cov yeeb nkab raws li kev txiav txim ntau lawm;

Thaum cov hlau txoj kab uas hla loj dua los yog sib npaug rau 0.5 hli, cov hlau yuav tsum tau kos rau ob feem peb ntawm cov yeeb nkab ntev, thiab thaum hla cov tub ntxhais magnesium, nws yuav tsum tau rub maj mam;

5. Tom qab hmoov ntxiv, qhov sib piv yuav tsum ncav cuag 2.4-2.6g/cm2;

6. Raws li lub finer kuj hlau txoj kab uas hla, kho qhov kev co kom me me li sai tau; Ceeb Toom: Qhov tshwm sim ntawm "sagging threads" tshwm sim

7. Thaum txhim kho lub hollow plug, nws yuav tsum tau ua kom ntseeg tau tias cov hlau lead tawm pas nrig tsis txav los yog tig, thiab lub ntsaws yuav tsum nruj nreem nias kom ntseeg tau tias cov hmoov tsis xau;

8. Thaum xaiv cov hmoov kab raj (ob lub raj raj), lub taub sab nraud ntawm lub raj xaim yuav tsum tsawg dua 0.5 hli ntawm lub taub sab hauv ntawm lub raj, thiab lub taub sab hauv ntawm lub raj xaim yuav tsum tsis txhob tshaj 0.5 hli ntawm qhov siab tshaj plaws sab nraud ntawm cov hlau;

9. Kev kuaj tus kheej voltage kuj thiab rwb thaiv tsev. Tsuas yog tom qab dhau qhov kev xeem tuaj yeem ua tiav cov txheej txheem tom ntej;

10. Kev ceev faj thaum ntxiv hmoov (cov lus qhia txheej txheem):

a. Visually soj ntsuam cov uniformity ntawm kauv kuj hlau. Stretching cov hlau tsis kam mus rau ib nrab ntawm qhov ntev ntawm lub raj thiab saib seb qhov ntom ntom yog qhov sib txawv;

b. Xyuas cov khoom, qhov ntev, thiab txoj kab uas hla ntawm cov hlau lead tawm pas nrig. Yog tias muaj kev khoov, nws yuav tsum tau ncaj;

c. Yog hais tias cov yeeb nkab yog khoov, nws yuav tsum tau ncaj.

d. Formula rau xam qhov hnyav ntawm cov hmoov ntxiv (tsis quav ntsej qhov hnyav ntawm cov hlau, txhuas tawm pas nrig, thiab ntsaws):

W=d2 · L · V ≈ 0.785 d2 · L · V

Nyob rau hauv cov mis: d - puab txoj kab uas hla ntawm cov yeeb nkab cm

L - Cov kav dej ntev cm

V-hmoov ceev 2. 4-2.6g/cm2

Fixture ntsuas cov cuab yeej thiab cov khoom siv: hmoov feeder, tsis siv neeg tawg tester, qhov cub, daim kab xev ntsuas, ntxuav phaj, roj av.

8, Shrink tube

1. Ua tib zoo so txhua qhov chaw ntawm cov yeeb nkab kom huv si;

2. Ua tib zoo saib xyuas cov kev taw qhia thaum shrinking lub raj thiab xyuas kom meej tias cov khoom ntsaws nkag mus rau hauv lub tshuab dov ua ntej (rau cov raj cua kub, nws raug nquahu kom shrink lub raj hauv ob qho tib si rau pem hauv ntej thiab rov qab cov lus qhia);

3. Txoj kab uas hla kev kam rau siab tom qab shrinking yog ± 0.08mm (xws li roundness kam rau ua);

4. Tom qab shrinking, qhov ncaj yuav tsum tsis txhob ntau tshaj 4mm ib 'meter';

5. Txhua zaus lub tshuab dov yog debugged, tsis pub ntau tshaj 8 daim yuav tsum tau debugged;

6. Cov kws tshuaj ntsuam xyuas yuav tsum random tshuaj xyuas txoj kab uas hla thiab qhov ncaj ntawm cov kav dej, thiab tshuaj xyuas 20% ntawm cov nqi tiv thaiv thiab cov yeeb nkab ntev.

Nco tseg: Tom qab shrinking, qhov sib txawv ntawm qhov ntev thiab luv luv ntawm cov yeeb nkab yuav tsum tsis pub tshaj 3% ntawm qhov yuav tsum tau "ntev ntawm cov yeeb nkab tom qab shrinking" nyob rau hauv qhov kev txiav txim ntau lawm; Thaum muaj qhov sib txawv tseem ceeb ntawm cov yeeb nkab ntev tom qab shrinkage uas tsis tuaj yeem khaws cia, cov khib nyiab yuav suav nrog hauv cov hmoov.

Fixture ntsuas cov cuab yeej thiab cov cuab yeej: shrinking tshuab, daim kab xev ntsuas, caliper.
