Hlau dabtsi yog khoov yog dav siv nyob rau hauv tsheb, aerospace, thiab hluav taws xob industries, tab siscaij nplooj ntoos hlav-qhov elastic rov qab tom qab khoov- ua rau muaj qhov tsis zoo, ua rau muaj qhov tsis zoo thiab cov nqi ntau dua. Hauv qab no yog cov feem ntau, cov tswv yim rebound tswj txoj kev kom ua tau zoo ib yam, muaj tseeb.
To taub hlau dabtsi yog khoov Rebound: Ua rau thiab cuam tshuam
Rebound tshwm sim vim rov qab elastic deformation tom qab khoov quab yuam raug tshem tawm. Nws qhov hnyav nyob ntawm cov khoom siv (yield zog, elasticity), khoov vojvoog, daim ntawv thickness, ceev, thiab cov cuab yeej tsim. Kev tswj tsis tau rov qab txo qhov raug, nce cov nqi seem, thiab tseem ceeb heev rau kev hais txog qhov siab - qhov tseeb.
Common Rebound Control Methods nyob rau hauv Hlau dabtsi yog khoov
Cov neeg tsim khoom feem ntau muab cov txheej txheem no los ua kom tau zoo, haum rau cov khoom siv, txheej txheem, thiab ib feem yuav tsum tau ua.
1.Overbending Method: Xa nyiaj rov qab nrog rov qab khoov
Txoj kev ncaj tshaj plaws: txhob txwm khoov hlau tshaj lub hom phiaj lub kaum sab xis kom offset rebound. Piv txwv li, khoov lub hom phiaj 90℃mus rau 95℃-100 degree; rebound yuav rov qab mus rau lub kaum sab xis xav tau.
Haum rau feem ntau cov ntaub ntawv (me me hlau, aluminium, tooj liab) thiab cov ces kaum yooj yim. Qhov tseem ceeb: Kev ntsuam xyuas los txiav txim siab qhov zoo tshaj plaws ntawm lub kaum sab xis, tshwj xeeb tshaj yog rau siab - cov ntaub ntawv elasticity zoo li stainless hlau.
2.Bottoming Bending (Nyiaj Bending): Tshem tawm Elastic Deformation
Siv lub zog siab los ua kom qhov chaw khoov, txo qis elastic deformation. Lub punch presses daim ntawv tag nrho tawm tsam qhov tuag, txo rov qab mus rau tsawg dua 1℃hauv qee kis.
Qhov zoo tshaj plaws rau siab -qhov precision (aerospace, kho mob) thiab nruab nrab - cov ntaub ntawv hardness. Tsis txhob siab- cov hlau hardness lossis nyias nyias los tiv thaiv kev puas tsuaj.
3.Kev kho cua sov: Txo cov khoom elasticity
Rau siab -elasticity hlau (stainless steel, titanium alloy), kev kho cua sov (annealing, kev ntxhov siab nyem) txo elasticity thiab kev ntxhov siab sab hauv, txo qis rov qab thaum lwm txoj kev ua tsis tiav.
Haum rau qhov nyuaj, siab -qhov tseeb. nruj me ntsis tswj cov ntsuas kub kom tsis txhob ua rau cov khoom puas.
4.Tool Design Optimization: Tsawg Rebound Los ntawm Pwm Txhim Kho
Txhim kho cov cuab yeej tsim kom txo qis rov qab: xaiv lub vojvoog khoov tsim nyog (1-2x daim ntawv tuab), me ntsis ua kom lub kaum sab xis loj, thiab cov cuab yeej txhuam hniav kom txo tau kev sib txhuam thiab kev ntxhov siab.
Tus nqi - zoo, haum rau txhua yam ntaub ntawv thiab cov txheej txheem, tsis tas yuav muaj cov khoom siv ntxiv.
5.Material Selection thiab Pretreatment: Txo Rebound los ntawm Qhov Chaw
Xaiv qis- elasticity, siab- cov ntaub ntawv yas (me me hlau, aluminium alloy) rau precision dabtsi yog khoov. Pretreat nplooj ntawv (pickling, ua ntej-bending) kom tshem tawm impurities thiab txhim kho khoov kev ua tau zoo.
6.CNC dabtsi yog khoov nrog tiag -Tshwj xeeb hloov kho: Kev txawj ntse Rebound Control
CNC dabtsi yog khoov tshuab nrog sensors ntes rebound nyob rau hauv lub sij hawm ntawm lub sij hawm, kho punch txoj hauj lwm / siab txiav rau zoo ib yam precision.
Zoo tagnrho rau huab hwm coj-tsim, siab- precision qhov chaw thiab cov ntaub ntawv nrog unstable rebound (nyias stainless hlau).
Tej yam uas cuam tshuam txog kev rov qab tswj tau zoo
Khoom siv: Siab zog yield zog / elasticity nce rebound.
Daim ntawv thickness: Cov nplooj ntawv tuab muaj tsawg dua; cov ntawv nyias nyias xav tau kev tswj xyuas meej.
Khoov vojvoog: Cov radii me me ua rau muaj zog dua.
Khoov ceev: Fast dabtsi yog khoov nce rebound; qeeb, khov kho khoov zoo dua.
Cov cuab yeej hnav: Cov cuab yeej hnav ua rau tsis sib xws; kev saib xyuas tsis tu ncua yog qhov tseem ceeb.
Cov tswv yim tswv yim rau kev tswj kom rov qab zoo
1.Test me me batch rau kho khoov tsis ua ntej loj ntau lawm.
2.Combine txoj kev (xws li, overbending + kev kho cua sov) rau siab precision.
3.Txhim kho cov cuab yeej tsis tu ncua kom ntseeg tau tias sib xws.
4.Saib cov kaum sab xis ntawm lub sijhawm thiab kho qhov ntsuas raws li xav tau.
5.Train neeg khiav dej num ntawm rebound txoj cai thiab tswj txoj kev.
Xaus
Rebound yog tswj tau nrog overbending, bottoming dabtsi yog khoov, kho cua sov, cuab yeej optimization, xaiv cov khoom, thiab CNC hloov. Xaiv txoj hauv kev raws li cov khoom siv, ib feem yuav tsum tau ua, thiab teev los txhim kho qhov tseeb, txo cov nqi, thiab txhawb kev ua haujlwm.
