Peb Qhov Zoo
1. Siab tsis kam
- Peb cov kav dej yog tsim los siv cov txheej txheem txias - kos duab, ua kom cov phab ntsa tuab tuab thiab zoo ib yam siab -siab tsis kam. Cov kav dej tau raug kuaj xyuas hydrostatic kom tsis txhob muaj dej los yog deformation nyob rau hauv siab.
- Cov txheej txheem kho cua sov ua kom zoo dua tuaj yeem txhim kho cov yeeb nkab toughness thiab lub zog, ua kom nws tuaj yeem tiv taus qhov cuam tshuam rov qab los ntawm kev kub siab thiab txo qhov kev pheej hmoo ntawm kev tawg.
2. Qhov tseeb qhov tseeb
- 4140 steel raj yog txias- kos ntau zaus siv lub tshuab CNC, ua kom muaj kev tswj xyuas nruj ntawm qhov ntev. Sab nraud txoj kab uas hla yog tswj nyob rau hauv ± 0.05 hli, thiab phab ntsa thickness kam rau ua nyob rau hauv ± 0.1 hli, txo cov nqi ua theem nrab.
- Ua ntej ntim, cov kav dej tau txais 100% kev tshuaj xyuas qhov loj me uas siv high -calipers precision, thickness gauges, thiab cov khoom siv ntsuas ncaj nraim kom ua tau raws li ASTM A519 cov qauv lossis cov neeg siv khoom xav tau.
3. Nto Zoo
- Peb txias- txheej txheem kos duab yields ib tug du nto nrog ib tug nto roughness ntawm Ra tsawg dua los yog sib npaug rau 1.6 μm. Rau cov kav dej siv hydraulic kheej kheej, peb txhawb honing, tumbling, thiab precision drilling.
- Peb cov kav dej tau raug kuaj xyuas qhov zoo kom ntseeg tau tias lawv tsis muaj khawb, nplai, tawg, thiab lwm yam tsis xws luag.
4. Machining thiab vuam kev ua tau zoo
- 4140 steel tube yog nkag rau hauv lub xeev annealed, tso cai rau kev tig ncaj qha, drilling, thiab tho txawv. Peb tswj nruj tswj xyuas qhov ntev thiab qhov zoo ntawm peb cov kav dej, txo qis kev ua haujlwm thib ob rau peb cov neeg siv khoom.
- Peb cov kav dej tau txais kev ntxhov siab- txheej txheem nyem tom qab kos duab txias los tiv thaiv cov kab nrib pleb los ntawm kev ntxhov siab thaum lub vuam.
5. Muaj peev xwm kho tau
- Peb muab cov kev daws teeb meem hloov kho kom haum raws li qhov xav tau ntawm ntau yam kev siv. Kev cai qhov ntau thiab tsawg, nto tiav, thiab kev kho cua sov tau txais kev txhawb nqa.
- Peb kuj muab ib qho -stop post- cov kev pabcuam xws li kev ua haujlwm ntxhib, honing, chamfering, threading, tho txawv, thiab tapping, txo cov nqi ua haujlwm thib ob rau peb cov neeg siv khoom.
thaj chaw thov
- Hydraulic system CheebtsamLub tog raj kheej hydraulic, piston pas nrig, hydraulic struts, hydraulic hoses.
- Transmission system Cheebtsam: tsav shafts, ib nrab shafts, txuas rods, rocker caj npab, pin tes tsho.
- Cov khoom siv ua haujlwm: Internal reinforcing hlab rau excavator booms / sticks, articulated tes tsho rau loader thoob, thiab lwm yam.
- Roj thiab roj: Drilling cov cuab yeej, pob qij txha, thiab cov khoom siv kho tshuab.
- Kev tsim kho thiab mining machinery: cov qauv thiab thauj khoom-cov kabmob xws li cov menyuam, qag, thiab cov tshuab hnyav.

FAQ
Q: Koj lub 4140 tubing yog dab tsi?
A: Peb lub raj xa dej tau muab rau hauv qhov kev mob annealed, tab sis peb kuj muab cov xwm txheej zoo li qub, Q&T, thiab lwm yam.
Q: Dab tsi yog qhov machinability ntawm cov tubing?
A: Peb lub raj xa tuaj rau hauv cov txheej txheem annealed los ntawm lub neej ntawd (hardness Tsawg dua lossis sib npaug rau 197HB), thiab tuaj yeem ncaj qha los ntawm kev tig, drilling, tho txawv, thiab lwm yam kev ua haujlwm.
Q: Lub raj puas tuaj yeem tau txais kev kho mob saum npoo?
A: Kev kho deg kev cai muaj xws li blackening, phosphating, galvanizing, thiab xeb - pov thawj txau; rau kev siv hydraulic, peb muab honing thiab tumbling polishing.
