Hauv phau ntawv qhia no, peb piav qhia lub hauv paus ua rau stamping distortion thiab sib qhia7 kev ua tau zoo, kev lag luam-qib txoj hauv kevkom koj cov khoom stamped zoo kawg nkaus tiaj thiab ncaj. Cov txheej txheem no siv rau steel, stainless hlau, tooj liab, tooj dag, thiab txhuas- cov khoom siv dav siv hauv precision stamping rau European thiab thoob ntiaj teb kev lag luam.
1. Nkag siab qhov ua rau Hlau Stamping rau Warp lossis Twist
Ua ntej kho distortion, koj yuav tsum paub yog vim li cas nws tshwm sim:
• Kev faib tawm tsis sib xws: Stamping tsim qhov tsis sib npaug / compression hla ntawm daim ntawv.
• Kev ntxhov siab ntawm cov khoom seem: Ua ntej- muaj kev ntxhov siab sab hauv hauv cov coils nyoos tawm thaum lub sij hawm stamping.
• Teeb meem cuab yeej: Hnav cov lus qhia, tsis sib npaug tuag, lossis tsis sib xws.
• Cov khoom tsis zoo tuav- cia: Tsis txaus clamping tso cai hloov.
• Kev tsim kho tsis zoo: Cov chaw tiaj tus loj, cov kaum ntse ntse, lossis cov duab tsis sib luag.
• Cov txheej txheem tsis raug: Ceev, siab, los yog lubrication mismatched rau cov khoom.
2. Optimize Part Design for Flatness & Stability
Tsim yog thawj kab ntawm kev tiv thaiv kev cuam tshuam. Ua raws li cov cai no:
• Ntxiv tav, hlaws, lossis embossing: Txhim kho qhov chaw tiaj tus loj kom tiv thaiv kev khoov.
•Siv symmetrical layouts: Cov duab sib npaug faib kev ntxhov siab sib npaug.
• Zam kev sib piv tsis zoo: Ntev, nqaim qhov chaw yog yooj yim rau twisting.
•Cuam cov ces kaum sib npaug & dav dav radii: Txo kev ntxhov siab concentration.
•Txhim nta nrog cov khoom lis: Tsim raws dov kev taw qhia kom txo qis springback.
• Ntxiv cov ntawv nyem nyem: Tiv thaiv kev ntxhov siab nyob rau hauv txoj kev khoov.
• Piv txwv: Lub cev sib txuas loj loj yuav hloov tau yooj yim - ntxiv 2-3 me me embossed tav dastically txhim kho kev ruaj ntseg.
3. Siv Kev Nyuaj Siab-Cov Khoom Siv Kho Mob lossis Cov Khoom Siv Kho Mob
Raw hlau coils feem ntau muaj kev ntxhov siab sab hauv los ntawm dov lossis cia.
•Xaiv kev ntxhov siab-relieved los yog annealed khoom: Lowers internal nro ua ntej stamping.
• Zam cov ntaub ntawv nyuaj/tempered: Siv cov qib ductile (piv txwv li, SPCE tsis yog SPCC) rau cov duab nyuaj.
• Tshawb xyuas cov khoom sib xws: Xyuas kom zoo ib yam thickness thiab hardness hla lub kauj.
• Cov Lus Qhia Pro: Rau siab - qhov tseeb tsheb / hluav taws xob qhov chaw, qhia meejannealed tooj liab alloyslos yogde-stressed hlaukom txo tau cov ntawv tshaj tawm -stamping distortion.
4. Master Tooling & Tuag tsim los tswj flatness
Tooling yog qhov loj tshaj plaws nyob rau hauv kom stamping ncaj.
• Muaj zog, sib npaug ntawm kev tuav: Siv cov khoom hnyav- lub luag haujlwm strippers nrog lub siab sib xws.
• Tapered stripper / tuag nto: Ntxiv 1-2℃rov qab taper los tiv thaiv kev sib tw.
•Precision qhia pins & bushings: Tshem tawm kev hloov pauv; tswj kev sib raug zoo.
•Progressive tuag theem: Muab faib ua thoob plaws ntau lub chaw nres tsheb kom txo tau kev ntxhov siab.
• Hnav- cov ntaub ntawv uas tiv taus tuag: Siv SKD11, DC53, lossis hmoov hlau kom ntev -lub sij hawm ruaj khov.
•Negative-angle pre-bending: Ua - hauv kev kho khoov rau offset springback.
Kev teeb tsa tseem ceeb: Teeb stripper qhov sib txawv rauKhoom thickness (t) - 0.03 ~ 0.05mmrau ruaj, txawm tias cov khoom siv tswj.
5. Optimize Stamping Process Parameters
Txawm tias zoo meej tsim & cov cuab yeej ua tsis raug nrog cov txheej txheem tsis raug:
• Sib npaug nias ceev & quab yuam: Tsis txhob khiav ceev heev uas ua rau muaj kev vibration lossis tsis sib xws.
•Sib txawv siab faib: Xyuas kom muaj zog sib npaug thoob plaws hauv cheeb tsam tuag.
• lubrication kom raug: Siv siab -kev ua tau zoo stamping lubricants los txo kev sib txhuam thiab kub.
• Tswj kev pub mis: Siv precision yob pub nrog cov lus qhia los tiv thaiv kev hloov.
• Tsis txhob overloading: Sib tw xovxwm tonnage rau qhov yuav tsum tau ua.
6. Tshaj tawm -Stamping Straightening & Stress Relief
Txawm tias muaj kev coj ua zoo tshaj plaws, qee qhov yuav tsum tau kho:
•Flatening/roller leveling: Hla qhov distorted los ntawm precision levelers los kho flatness.
• Thaum tshav kub kub kev ntxhov siab: Tsawg-kub annealing (150–250 degree) los so kom txaus siab qhov seem uas tsis tau hloov qhov ntev.
• Tes straightening (rau cov khoom me me): Siv precision jigs thiab maj mam nias rau kev kho me.
Nco tseg: Rau RoHS/ELV-cov khoom ua raws, xyuas kom meej tag nrho cov txheej txheem thiab cov roj nplua nyeem ua tau raws li EU ib puag ncig cov qauv.
7. Kev Tswj Xyuas Zoo & Kev Tu
•Nyob hauv-kev saib xyuas: Txheeb xyuas qhov flatness nrog ntsuas, ntsuas qhov siab, lossis optical projectors.
• Kev tu cov cuab yeej tsis tu ncua: Nthuav cov punches / tuag, hloov cov lus qhia hnav, thiab rov-calibrate siab txhua 50,000 strokes.
• Kev tshuaj xyuas cov khoom: Ntsuas cov coils tuaj rau kev ntxhov siab, hardness, thiab uniformity.
•Document tag nrho cov parameters: Cov ntaub ntawv ceev, siab, lubrication, thiab cov cuab yeej ua kom zoo sib xws.
Xaus: Ncaj Stamping=Kev Zoo & Nqi Txuag
Ua kom hlau stamping ncaj yuav tsum muaj txoj hauv kev holistic:ntse tsim, siab- cuab yeej zoo, kev ntxhov siab- cov ntaub ntawv pub dawb, cov txheej txheem ua kom zoo, thiab QC nruj. Los ntawm kev ua raws li 7 txoj hauv kev no, koj tuaj yeem txo qis cov nqi seem, txhim kho qhov tseeb ntawm qhov tseeb, thiab ua tau raws li kev ua siab ntev xav tau los ntawm European tsheb, hluav taws xob, thiab cov neeg siv hluav taws xob tauj dua tshiab.
Rau precision stampings-tshwj xeeb yog cov yuav tsum tauKev ua raws RoHS/ELVthiab IATF 16949 zoo- flatness thiab stability tsis yog -negotiable. Koom tes nrog cov neeg muag khoom muaj kev paub dhau los uas tseem ceeb rau kev tiv thaiv -warping tsim thiab tswj cov txheej txheem kom zoo ib yam, siab - cov txiaj ntsig zoo.
