Muaj ntau ntau txoj kev machining, thiab hom machined workpieces kuj muaj ntau yam. Ntau hom workpieces muaj ntau txoj kev machining, thiab ntau hom workpieces kuj muaj qhov sib txawv machining technical.
General kev cai rau machining ntawm castings:
1. Txias kaw, tawg, shrinkage kab noj hniav, nkag mus rau qhov tsis xws luag thiab loj tsis tiav tsis xws luag (xws li nyob rau hauv casting, mechanical puas tsuaj, thiab lwm yam) yog tsis tso cai rau saum npoo ntawm castings.
2. Lub casting yuav tsum tau ntxuav tsis muaj burrs thiab flash. Lub pouring thiab riser ntawm qhov tsis yog machining qhia yuav tsum tau ntxuav thiab yaug nrog lub casting nto.
3. Cov lus cam khwb cia thiab cov cim rau ntawm qhov tsis machined nto ntawm lub casting yuav tsum meej thiab pom tseeb, thiab txoj hauj lwm thiab font yuav tsum tau raws li qhov yuav tsum tau ntawm daim duab.
4. Qhov roughness ntawm qhov tsis machined nto ntawm lub casting, xuab zeb casting R, tsis ntau tshaj 50 μ m.
5. Lub pouring riser thiab ya pos yuav tsum tau muab tshem tawm ntawm lub casting. Cov residue ntawm pouring thiab riser rau ntawm qhov tsis machined nto yuav tsum tau leveled thiab polished kom tau raws li qhov yuav tsum tau ua kom zoo.
6. Cov xuab zeb molding, core xuab zeb thiab cov pob txha tseem ceeb ntawm lub casting yuav tsum raug tshem tawm.
7. Yog hais tias lub casting muaj inclined qhov chaw, nws qhov seem kam rau ua cheeb tsam yuav tsum tau symmetrically configured raws lub inclined dav hlau.
8. Cov xuab zeb moulding, core xuab zeb, core pob txha, fleshy, nplaum xuab zeb, thiab lwm yam ntawm cov casting yuav tsum tau spaded, av thiab ntxuav.
9. Hom tsis ncaj ncees lawm thiab kev sib txawv ntawm tus thawj coj yuav tsum raug kho kom ua tiav qhov kev hloov pauv thiab ua kom pom qhov zoo.
10. Qhov tob ntawm cov folds ntawm qhov tsis machined nto ntawm lub casting yuav tsum tsawg tshaj li 2 hli, thiab qhov sib nrug yuav tsum ntau tshaj 100 hli.
11. Lub tshuab tsis siv lub tshuab cov khoom castings yuav tsum raug tua los yog cov menyuam kho kom ua tau raws li qhov yuav tsum tau ua ntawm kev huv SA2 1/2.
12. Castings yuav tsum tau kho cov dej toughening.
13. Lub casting nto yuav tsum tiaj tus, thiab lub rooj vag, burr, xuab zeb nplaum, thiab lwm yam.
14. Castings tsis raug tso cai kom muaj qhov txias txias, tawg, qhov thiab lwm yam castings uas ua rau tsis zoo rau kev siv.
Cov txheej txheem kev cai rau forging machining:
1. Lub nozzle thiab riser ntawm forgings yuav tsum muaj qhov txaus txiav kom paub meej tias forgings tsis muaj shrinkage thiab loj deflection.
2. Forgings yuav tsum tau forged rau ntawm forging xovxwm uas muaj peev xwm txaus los xyuas kom meej tias sab hauv forgings yog tag nrho forged.
3. Forgings tsis raug tso cai kom pom cov kab nrib pleb, folds thiab lwm yam tsis xws luag uas cuam tshuam rau kev siv. Cov teeb meem hauv zos tuaj yeem raug tshem tawm, tab sis qhov tob ntawm kev ntxuav yuav tsum tsis pub tshaj 75 feem pua ntawm cov nyiaj siv ua haujlwm. Qhov tsis xws luag ntawm qhov uas tsis yog machined nto ntawm forgings yuav tsum tau ntxuav thiab smoothly transited.
4. Forgings tsis raug tso cai kom muaj cov pob dawb, cov kab nrib pleb sab hauv thiab cov kab noj hniav seem.
Cov txheej txheem kev cai rau machining ntawm Weldments:
1. Qhov tsis xws luag yuav tsum tau muab tshem tawm tag nrho ua ntej vuam, thiab qhov zawj saum npoo yuav tsum tiaj tus thiab du yam tsis muaj qhov ntse ntse.
2. Cov chaw tsis zoo ntawm cov vuam tuaj yeem raug tshem tawm los ntawm kev khawb qhov khawb, sib tsoo, carbon arc gouging, roj txiav lossis machining.
3. Xuab zeb, roj, dej, xeb thiab lwm yam av nyob rau hauv 20mm nyob ib ncig ntawm lub vuam thiab zawj yuav tsum tau muab ntxuav kom huv si.
4. Nyob rau hauv tag nrho cov txheej txheem ntawm vuam, qhov kub ntawm preheating cheeb tsam yuav tsum tsis txhob qis tshaj 350 degree C.
5. Yog tias muaj kev tso cai, weld ntawm txoj haujlwm kab rov tav kom deb li deb tau.
6. Thaum kho vuam, lub vuam pas nrig yuav tsum tsis txhob viav vias tom qab.
7. Thaum lub sij hawm deg stacking welding, qhov sib tshooj ntawm weld hlaws yuav tsum tsis pub tsawg tshaj 1/3 ntawm qhov dav weld hlaws. Cov nqaij welding yog tag nrho, thiab qhov chaw vuam tsis muaj qhov kub hnyiab, tawg thiab pom tseeb nodules.
8. Cov weld zoo li zoo nkauj, thiab tsis muaj qhov tsis xws li nqaij tom, slag ntxiv, pores, tawg, tawg, thiab lwm yam; Lub vuam yoj yog txawm.
Cov txheej txheem kev cai rau machining ntawm tej qhov chaw:
1. Cov khoom yuav raug tshuaj xyuas thiab lees txais raws li cov txheej txheem ua, thiab tuaj yeem hloov mus rau cov txheej txheem tom ntej tsuas yog tom qab cov txheej txheem dhau los tsim nyog.
2. Cov khoom ua tiav tsis pub muaj burrs.
3. Cov khoom tom qab ua tiav yuav tsum tsis txhob muab tso ncaj qha rau hauv av, thiab kev txhawb nqa thiab kev tiv thaiv yuav tsum tau ua. Lub tshuab nto yuav tsum tsis muaj xeb thiab lwm yam tsis xws luag xws li pob thiab khawb uas cuam tshuam rau kev ua haujlwm, kev pabcuam lub neej lossis kev pom.
4. Yuav tsum tsis txhob tev tawm ntawm qhov chaw tom qab dov thiab ua tiav.
5. Qhov saum npoo ntawm qhov chaw tom qab kev kho cua sov hauv cov txheej txheem kawg yuav tsum tsis muaj oxide ntawm daim tawv nqaij. Lub mating nto thiab hniav nto tom qab ua tiav yuav tsum tsis txhob annealed
6. Lub machined xov nto tsis raug tso cai kom muaj qhov tsis xws luag xws li cov tawv nqaij dub, pob, tsis sib haum xeeb buckle thiab burr.
Cov khoom sib txawv muaj cov kev xav tau sib txawv rau kev ua haujlwm. Tsuas yog los ntawm kev ua raws li cov txheej txheem kev cai, peb tuaj yeem ua kom zoo dua ntawm cov khoom ua haujlwm.
