Yuav ua li cas Annealing dictates Formability txwv ntawm me me -Txoj kab uas hla Stainless hlau

Nyob rau hauv lub realm ntawm precision kho mob khoom manufacturing, zoo ntawmSwaged Koobfeem ntau txiav txim siab tsis yog los ntawm cov txheej txheem polishing kawg, tab sis los ntawm microstructure muab zais hauv cov hlau nws tus kheej. Tshwj xeeb tshaj yog rau stainless hlau koob raj li ntawm 0.25mm mus rau 30mm nyob rau hauv txoj kab uas hla, sib npaug hardness thiab ductility los ntawm kev kho cua sov yog ib qho tseem ceeb rau kev tiv thaiv kev tawg los yog puas thaum lub sij hawm tom ntej los yog kev kho mob siv. Qhov tsab xov xwm no delves rau hauv lub luag hauj lwm txiav txim siab ntawm annealing nyob rau hauv zus tau tej cov Swaged Needles.

Stainless hlau, tshwj xeeb tshaj yog kev kho mob -qib 304 thiab 316L, feem ntau muaj nyob rau hauv txias- ua hauj lwm lub xeev thaum xa khoom, muaj zog tensile siab thiab hardness. Txawm li cas los xij, lub xeev nruj no ua rau muaj kev pheej hmoo tseem ceeb rau cov koob raj uas xav tau cov yas deformation ntau heev. Whether swaging the tail to lock a suture or bending the tube into specific curvatures, the metallic lattice is subjected to immense shear forces. Yog tias cov khoom nyuaj dhau lawm, cov lattice tsis tuaj yeem plam kom tso tawm kev ntxhov siab, ua rau cov qoob loo sib cais- tshwm sim macroscopically raws li pom cov kab nrib pleb lossis micro- tawg.

Qhov no yog qhov uas cov txheej txheem annealing dhau los ua qhov tseem ceeb. Annealing yog ib tug precisely tswj cua sov thiab cua txias voj voog. Hauv peb cov kab ntau lawm, tshwj xeeb tshaj yog rau micro- txoj kab uas hla (piv txwv li, 0.25mm), peb siv cov annealing ci ntsa iab lossis hauv zos induction annealing. Los ntawm cua sov lub koob raj mus rau qhov ntsuas kub tseem ceeb (feem ntau ntawm 1010℃thiab 1120 degree, nyob ntawm qhov tshwj xeeb alloy) thiab tuav nws rau lub sijhawm teem sijhawm, atoms tau txais lub zog kinetic txaus los hloov kho, tshem tawm cov kev ntxhov siab sab hauv los ntawm kev kos duab txias lossis swaging. Tom qab ntawd, tswj kev ua kom txias qeeb tso cai rau cov hlau lub microstructure rau recrystallize thiab loj hlob, txo cov yield zog thiab hardness thaum ua kom elongation (ductility).

Rau Swaged Needles, annealing pab lub hom phiaj tshaj li "softening." Qhov tseem ceeb, nws imparts resilience. Thaum lub sij hawm rotary swaging, siab - ceev hammering radially compresses rab koob, txo nws txoj kab uas hla mus tuav lub suture nruj nreem. Yog tias tsis muaj kev sib txhuam kom zoo, xws li cov yas deformation tam sim ntawd ua rau kev ua hauj lwm hardening, uas yuav ua rau cov kab nrib pleb. Hloov pauv, zoo- cov hlab ntim tau tso cai rau cov iav siv lead ua kom tiv taus qhov deformation hnyav yam tsis muaj qhov tawg. Tsis tas li ntawd, rau kev txhaj tshuaj thiab puncture cov cuab yeej uas yuav tsum tau ua peb txoj kev khoov-, qhov kho kom zoo nkauj ua kom cov phab ntsa sab nrauv ntawm qhov khoov tsis tsim kua muag nyob rau hauv tensile stress.

Hauv kev xyaum, kev tswj cov kev ntsuas annealing yog kev tshawb fawb meej. Cov kub ntau dhau ua rau cov qoob loo loj hlob tsis zoo; Thaum softening cov khoom, qhov no txo ​​lub zog thiab txhawb kev tsim ntawm brittle oxide nplai. Qhov kub tsis txaus tsis tuaj yeem txo qhov kev ntxhov siab sab hauv, tsis zoo rau qhov xav tau softening nyhuv. Peb ISO13485 Kev Tswj Xyuas Kev Tswj Xyuas Zoo tau tswj hwm nruj SPC (Kev Tswj Xyuas Txheej Txheem Txheej Txheem) saib xyuas ntawm txhua qhov kev sib tsoo. Rau ultra- zoo 0.25mm raj, nrog tsawg kawg nkaus lub peev xwm kub thiab siab rhiab heev rau thermal fluctuations, siab - zaus induction cua sov ua ke nrog inert gas shielding yog ua hauj lwm. Qhov no ua kom cov qauv metallographic tsis sib xws nyob thoob plaws lub batch, nteg cov khoom siv ruaj khov rau cov txheej txheem tom ntej swaging, khoov, thiab flaring. Hauv cov ntsiab lus, cov txheej txheem annealing yog lub hauv paus tsis pom ntawm Swaged Needle manufacturing, ncaj qha dictating cov khoom qhov kev ua tau zoo tshaj plaws hauv kev tiv thaiv kev tawg thiab tawg thaum cov txheej txheem kho mob nyuaj.
