I. UA NTEJ -} Kev Npaj Npaj Vuam
1. Khoom Soj Ntsuam
Paub meej tias lub zog hluav taws xob voltage yog ruaj khov (220V ± 10% lossis 380V peb {{}} theem zog). Kuaj xyuas tias cov kab ke hydraulic, cua sov phaj, thiab tswj vaj huam sib luag ua haujlwm tau zoo.
Preheat cov cua sov phaj rau lub teeb kub (210 ± 10 ± 10℃rau PE100) thiab tswj qhov kub rau 1-2 feeb kom tso cai rau qhov kub thiab txias.
2. Hlau Kev Npaj
Siv lub cutter milling los txiav cov yeeb nkab kawg ntseeg tau, dawb ntawm burrs thiab tawg, nrog rau kev ua tsis ncaj tshaj lossis sib npaug ntawm cov phab ntsa tuab.
Ntxuav cov yeeb nkab xaus thiab cov cua kub phaj kom txhob muaj roj thiab hmoov av uas yuav cuam tshuam weld zoo.
Ii. Vuam cov kev ua haujlwm ua haujlwm
1. Clamping thiab milling
Ruaj rau cov yeeb nkab hauv lub tshuab ncej chuck thiab kho cov tshuaj. Lub misalignment yuav tsum tsawg dua los yog sib npaug rau 10% ntawm phab ntsa tuab.
Pib lub milling cutter los txiav cov yeeb nkab kawg. Tom qab tsim cov nti txuas ntxiv, tshem tawm cov milling cutter thiab ntxuav cov chips. (Tsis txhob kov lub weld nto nrog koj txhais tes.) 2. Cua sov thiab taub qab sib koom ua ke
Muab cov cua kub lub phaj, kaw lub tshuab thav duab, thiab nias rau cov vuam siab (P {}} Pg rub + P2). Soj ntsuam lub flange qhov siab (feem ntau 1.5 hli).
Lub sijhawm nqus kub nqus tau raug suav raws li cov phab ntsa tuab (piv txwv li phab ntsa thickness x 10 vib nas this). Lub sijhawm hloov yuav tsum tsawg dua lossis sib npaug li 10 vib nas this. Sai sai tshem tawm cov cua kub thiab kaw cov yeeb nkab.
III. Txias thiab tshuaj xyuas
1. Siab - Tswj kom txias
Lub sijhawm txias yog teeb raws li cov leeg lub taub yeeb (piv txwv li, 11-3 feeb rau 90-315mm kav dej). Tswj lub zog ruaj khov thaum lub sijhawm no.
Tom qab txias, txo cov siab rau xoom ua ntej tshem tawm cov fixture kom tsis txhob rub cov weldment.
2. Kev Soj Ntsuam Zoo
Visually soj ntsuam lub nplhaib weld: dav 0.35-0.45 zaug ntawm phab ntsa tuab, qhov siab 0.2-0.25 zaug ntawm phab ntsa tuab, thiab tsis muaj npuas lossis dents.
Yog tias tsim nyog, ua tensile lossis ultrasonic kuaj kom paub tseeb tias qhov tsis muaj kev tsis taus sab hauv.
IV. Kev ceev faj kev nyab xeeb
Protective Equipment: Heat-insulating gloves (temperature resistant ≥ 300°C), safety glasses, and non-slip safety shoes must be worn. Environmental requirements: Avoid strong winds (>5m / s), Los nag, thiab tsawg kub (<5°C), and be equipped with a fire extinguisher.
