COG PRINDING
Siv kom zoo dua ntawm cov yam ntxwv ntawm cov hlau nplaum ntawm cov hlau, lub metrepchocic conformation ntawm qhov chaw ua haujlwm, yog li txo qhov chaw roughness. Kev siab siab yog siv rau hauv cov pwm kab noj hniav kom ua rau cov pwm puab. Suav nrog nto rolling, saum npoo extrusion Ua, thiab lwm yam haum rau Polycarbonate, Polypropylene thiab lwm yam ntaub ntawv. Los ntawm kev ua kom txias ua tiav, lub tensile muaj zog thiab elastic moldulus ntawm cov khoom tuaj yeem hloov kho.
Kev zam
Xaiv cov khoom siv hlau khoom thiab ua cov khoom siv hlau tsim nyog, xws li kev txiav, thiab lwm yam kub kom nws cov plasticity tsis kam. Nyob rau hauv lub tshuab los yog nias ntawm ib qho kev zam txim rauj lossis nias, cov hlau tsis zoo ntws plastically hauv cov pwm kom tsim qhov xav tau. Cov hlau yog pub dawb rau txhua cov lus qhia siv kev cuam tshuam yuam kev lossis forging.forged rau qhov tseeb hauv qhov loj me.Qhov kev Forging ua tiav, kev Forging yog txias kom ruaj ntseg nws cov duab thiab kev ua tau zoo. Xws li kev kho cua sov, machines thiab kev kho deg, thiab lwm yam, txhawm rau txhim kho kev ua tau zoo thiab kev tsis lees paub.
Mandrel Txoj Kev
Tsim tsim nyog tus ncej thiab qhov loj raws li kev ua haujlwm machining. Precision hlau ua tshuab, xws li tig, sib tsoo, thiab lwm yam, yog siv los tsim cov high-precision mandrel. Nruab qhov tsim tawm mandrel rau kev ua cov khoom siv xws li cov khoom siv ua haujlwm lossis cov grinders thiab debug nws kom ntseeg tau tias nws tuaj yeem txhawb nqa qhov chaw ua haujlwm stably. Thaum ua nyias-walled hlau kav hlau, manrel feem ntau tau ntxig rau hauv cov yeeb nkab sab hauv, thiab kev txhawb nqa radial zam zam kev zam kom zam dhau kev ua txhaum cai siab.
Dav dav loj me ntsis
Lub 90-degree lub luj tshib muaj ntau cov ntawv thov hauv roj av, kev lag luam tshuaj, roj thiab lwm daim teb. Nws cov kev qhia tshwj xeeb thiab qhov ntev ua raws nrog ntau cov qauv txheem. Raws li cov qauv siv hauv tebchaws GB / T 12459-2017 thiab ASME B16.9 cov qauv, cov ntsuas hluav taws xob tshwj xeeb ntawm 90-depitional voj voog yog txhua millimeters (hli)
