Pistol Pivot Titanium Alloy Poob-Wax Casting

Ua ntej, ib tug meej pwm yog ua raws li tus tsim drawings ntawm rab yaj phom swivel. Cov pwm no feem ntau yog ua los ntawm cov hlau lossis lwm yam khoom siv thiab muaj cov duab zoo ib yam thiab qhov ntev ntawm lub voj voog. Tom qab ntawd, molten wax yog poured rau hauv pwm, txias, thiab tshem tawm kom tau ib tug siv quav ciab qauv uas phim cov duab ntawm rab yaj phom swivel. Thaum lub sij hawm tsim cov qauv siv quav ciab, qhov kub thiab qhov dej ntawm cov quav ciab yuav tsum tau tswj nruj me ntsis kom ntseeg tau qhov zoo ntawm cov qauv siv quav ciab. Qhov saum npoo zoo thiab qhov tseeb qhov tseeb ntawm cov qauv siv quav ciab ncaj qha cuam tshuam rau qhov zoo ntawm qhov kawg casting. Yog li ntawd, ua tib zoo machining thiab ua tiav yuav tsum tau tshem tawm cov imperfections saum npoo thiab ntau cov quav ciab.

Plhaub Tsim: Cov qauv siv quav ciab tau muab tso rau hauv cov txheej txheem tshwj xeeb, kom ntseeg tau tias cov txheej txheej tsis sib xws. Cov txheej no feem ntau muaj cov ntaub ntawv refractory, cov ntaub qhwv, thiab cov khoom siv ntxiv, muaj cov khoom zoo heev - kub ua hauj thiab adhesion zog. Tom qab ntawd, ib txheej ntawm cov xuab zeb yog sprinkled rau ntawm cov qauv siv quav ciab, cia nws ua raws li cov txheej txheem. Cov txheej txheem no rov ua dua ntau zaus kom txog thaum lub plhaub ntawm ib qho tuab yog tsim. Lub plhaub no yuav ua cov pwm thaum lub sij hawm casting, withstanding lub siab thiab kev cuam tshuam ntawm high - kub molten hlau.

Thaum lub plhaub tsim, nws yog ib qho tseem ceeb rau kev tswj cov txheej txheej concentration, xuab zeb particle loj, thiab uniformity ntawm daim ntawv thov xuab zeb los xyuas kom meej lub plhaub lub zog thiab permeability. Lub plhaub tsis txaus tuaj yeem ua rau tawg thaum lub sij hawm casting, ua rau muaj qhov tsis xws luag hauv qhov casting; tsis zoo permeability tiv thaiv roj los ntawm kev khiav tawm, tsim pores hauv cov casting thiab cuam tshuam rau nws qhov zoo.

Dewaxing: Cov qauv siv quav ciab nrog nws lub plhaub tau muab tso rau hauv qhov kub ntawm - qhov kub thiab txias rau qhov kub thiab txias, ua rau cov qauv siv quav ciab yaj thiab ntws tawm ntawm lub plhaub. Cov txheej txheem no yuav tsum tau tswj cov cua kub thiab qhov kub thiab txias los tiv thaiv cov pwm pwm los ntawm melting sai heev thiab ua rau lub plhaub sab nrauv tawg. Tom qab dewaxing, ib kab noj hniav uas zoo ib yam li rab yaj phom lub voj voog yog tsim nyob rau hauv lub plhaub sab nrauv, tos cov filling nrog molten hlau.

Smelting Titanium Alloy: titanium alloy raw khoom yog muab tso rau hauv lub tshuab nqus tsev induction rauv rau melting. Thaum lub sij hawm melting txheej txheem, qhov kub, lub tshuab nqus tsev, thiab lub sij hawm melting nyob rau hauv lub cub tawg yuav tsum nruj me ntsis tswj kom lub uniformity thiab purity ntawm titanium alloy muaj pes tsawg leeg. Vim yog cov tshuaj lom neeg muaj txiaj ntsig ntawm titanium alloy, nws nkag siab nrog cov ntsiab lus xws li oxygen thiab nitrogen hauv huab cua; Yog li ntawd, melting yuav tsum tau nqa tawm nyob rau hauv ib qho chaw nqus tsev vacuum los tiv thaiv kev taw qhia ntawm impurities.

Pouring: Tom qab cov titanium alloy yog melted, nws yog rhuab mus rau ib tug haum pouring kub, thiab ces cov molten hlau yog sai sai poured rau hauv pwm nrog ib tug txheej txheej. Cov txheej txheem pouring yuav tsum ceev ceev thiab raug los xyuas kom meej tias cov hlau molten nyob rau hauv tag nrho cov kab noj hniav, tsis txhob muaj xws li tsis tiav filling thiab txias kaw. Nyob rau tib lub sijhawm, lub pouring ceev thiab siab yuav tsum tau tswj los xyuas kom meej qhov zoo ntawm cov casting.

Ntxuav thiab Post-kev kho mob: Tom qab nchuav, cov casting raug tso cai kom txias. Tom qab ntawd, lub plhaub sab nraud raug tshem tawm, thiab cov casting yog ntxuav kom tshem tawm cov impurities thiab oxide nplai. Tom ntej no, lub casting undergos machining thiab tshav kub kev kho mob los txhim kho nws hardness, lub zog, thiab toughness. Machining muaj xws li tig, sib tsoo, thiab drilling kom ua tiav qhov yuav tsum tau muaj qhov ntev thiab qhov roughness. Kev kho cua sov, xws li annealing, quenching, thiab tempering, yog xaiv raws li hom titanium alloy thiab nws cov ntawv thov los txhim kho nws cov microstructure thiab cov khoom.

Dimensional Accuracy Inspection: High -cov cuab yeej ntsuas qhov tseeb, xws li kev sib koom tes ntsuas tshuab thiab calipers, yog siv los ntsuas qhov ntev ntawm cov phom cam khwb cia. Cov qhov ntev tseem ceeb, xws li txoj kab uas hla, qhov ntev, thiab txoj kab uas hla, raug kuaj xyuas kom ntseeg tau tias lawv ua tau raws li cov qauv tsim. Dimensional raug ncaj qha cuam tshuam qhov haum ntawm lub ncej thiab lwm yam khoom thiab yuav tsum tau tswj nruj me ntsis. Yog tias qhov sib txawv ntawm qhov sib txawv dhau qhov kev txwv, nws yuav ua rau muaj teeb meem sib dhos lossis kev ua haujlwm tsis zoo hauv rab phom.

Surface Quality Inspection: Cov ncej saum npoo yog tshuaj xyuas qhov tsis xws luag xws li cov kab nrib pleb, porosity, thiab xuab zeb qhov siv kev tshuaj xyuas qhov muag thiab metallographic microscopy. Qhov zoo ntawm qhov chaw tsis yog tsuas yog cuam tshuam rau rab yaj phom zoo nkaus li tab sis kuj tseem tuaj yeem cuam tshuam rau cov ncej ntawm corrosion kuj thiab hnav tsis kam. Yog tias muaj qhov tsis xws luag, yuav tsum tau kho lossis rov ua dua.

Internal Quality Inspection: Tsis yog-Kev kuaj kev puas tsuaj, xws li kev kuaj ultrasonic thiab X-ray tshuaj ntsuam xyuas, yog siv los kuaj xyuas qhov tsis xws luag hauv qhov pivot, xws li cov kab nrib pleb thiab suav nrog. Cov teeb meem no tuaj yeem nthuav tawm thaum siv, ua rau pivot tawg thiab cuam tshuam rau rab yaj phom kev nyab xeeb. Tsis yog-kev kuaj kev puas tsuaj tuaj yeem kuaj pom qhov tsis xws luag hauv qhov tsis muaj kev puas tsuaj rau cov casting, kom ntseeg tau qhov zoo ntawm cov casting.

Kev Ntsuam Xyuas Kev Ua Haujlwm: Kev ntsuas cov cuab yeej cuab tam, xws li kev ntsuas tensile thiab hardness test, yog ua nyob rau hauv pivot los ntsuas nws lub zog, toughness, thiab hardness. Kev sim qaug zog kuj tuaj yeem ua rau simulate qhov kev ntxhov siab ntawm rab yaj phom thaum siv tiag tiag thiab sim pivot lub neej qaug zog. Kev ntsuas kev ua tau zoo ua kom ntseeg tau tias lub pivot ua tau raws li rab yaj phom qhov kev ua tau zoo hauv kev siv tiag tiag.
