Taw qhia:
Quilted seamless yeeb nkab yog ib hom high precision steel yeeb nkab khoom tom qab txias txias los yog kub dov.Vim tias tsis muaj oxide txheej ntawm cov phab ntsa sab hauv thiab sab nrauv ntawm cov yeeb nkab steel, [1] nyob rau hauv kev kub siab yam tsis muaj to, siab precision, siab tiav, txias dabtsi yog khoov yam tsis muaj deformation, flaring, flattening tsis tawg thiab lwm yam, nws yog tsuas yog siv. rau kev tsim cov pneumatic lossis hydraulic Cheebtsam, xws li lub tog raj kheej lossis lub tog raj kheej, uas tuaj yeem ua seamless.Cov tshuaj muaj pes tsawg leeg ntawm quilted seamless raj yog carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr
Quilted seamless yeeb nkab txais kev siv tshuab
Lub quilted seamless yeeb nkab yog ua tiav los ntawm dov.Vim yog qhov seem compressive kev ntxhov siab ntawm cov txheej txheej saum npoo, nws yog qhov zoo los kaw cov kab nrib pleb ntawm qhov chaw thiab tiv thaiv kev nthuav dav ntawm kev yaig.Nws tuaj yeem txhim kho qhov kev tiv thaiv corrosion thiab ncua lub tiam los yog nthuav tawm ntawm qaug zog tawg, thiaj li txhim kho lub zog qaug zog ntawm quilted steel yeeb nkab.Los ntawm dov txoj kev, ib tug txias ua hauj lwm hardening txheej yog tsim nyob rau hauv dov nto, uas yuav txo tau cov elastic thiab yas deformation ntawm kev sib cuag nto ntawm lub sib tsoo khub, yog li txhim kho cov hnav tsis kam ntawm lub puab phab ntsa ntawm cov quilted steel yeeb nkab thiab tsis txhob hlawv. tshwm sim los ntawm kev sib tsoo.Tom qab dov, qhov txo qis ntawm qhov roughness tuaj yeem txhim kho cov khoom haum.
Rolling machining yog ib hom chip dawb machining.Ntawm qhov kub thiab txias, cov yas deformation ntawm cov hlau yog siv los ua kom lub microscopic roughness ntawm lub workpiece nto kom ua tiav lub hom phiaj ntawm kev hloov cov qauv saum npoo, txhua yam yam ntxwv, cov duab thiab qhov loj me.Yog li, txoj kev no tuaj yeem ua tiav ob lub hom phiaj ntawm polishing thiab ntxiv dag zog rau tib lub sijhawm, uas tsis tuaj yeem ua kev sib tsoo.
Tsis muaj teeb meem dab tsi ntawm kev ua cov txheej txheem yog siv los ua cov txheej txheem, yuav tsum muaj qhov zoo sib xws thiab concave tsis sib xws riam cov cim rau ntawm qhov chaw, thiab qhov tshwm sim ntawm staggered peaks thiab hav,
Rolling processing txoj cai: Nws yog ib hom kev ua tiav siab, yog kev siv hlau nyob rau hauv qhov kub thiab txias ntawm cov yam ntxwv ntawm cov yas yas, siv cov cuab yeej dov los ua kom lub zog ntawm qhov chaw ua haujlwm, kom lub workpiece nto hlau yas. ntws, sau rau hauv qhov qub residual qis concave trough, thiab ua tiav lub workpiece nto roughness tus nqi txo.Vim yog cov yas deformation ntawm cov dov saum npoo hlau, cov ntaub so ntswg txias hardening thiab grain thinning, tsim cov fiber ntau ntom, thiab tsim cov residual kev nyuaj siab txheej, hardness thiab lub zog, yog li txhim kho cov hnav tsis kam, corrosion kuj thiab compatibility. workpiece nto.Rolling yog ib txoj kev machining yas yam tsis tau txiav.
Quilted seamless yeeb nkab ntau qhov zoo:
1, txhim kho qhov chaw roughness, roughness tuaj yeem ncav cuag Ra≤0.08µm lossis li ntawd.
2, qhov tseeb roundness, ellipticity yuav tsawg dua 0.01mm.
3, txhim kho qhov tawv tawv, lub zog deformation raug tshem tawm, hardness nce HV≥4 °
4, tom qab ua cov txheej txheem kev ntxhov siab, txhim kho lub zog qaug zog los ntawm 30%.
5, txhim kho qhov zoo ntawm qhov haum, txo qhov hnav, ua kom lub neej ntev ntawm cov khoom siv, tab sis tus nqi ntawm cov khoom raug txo.
