Tus ntawv tshuaj: Qhov kev pab cuam ntawm kev ua haujlwm CNC Wire EDM thiab qhov siv ntawm lawv rau kev ua haujlwm tshwj xeeb

Nyob rau hauv qhov chaw ntawm kev tsim kho tshuaj tshiab thiab kev kho tshuaj tsis yog kev kho tshuaj tseem ceeb, CNC Wire Electrical Discharge Machines (WEDM), uas yog ib qho tseem ceeb ntawm Electrical Discharge Machining (EDM), tau ua haujlwm txaus siab rau lawv. Tsis zoo li kev kho tshuaj tseem ceeb uas nyob rau lub zog kho tshuaj, WEDM ua haujlwm los ntawm kev tshem tawm ntau yam ntau thiab kev tshem tawm ntau yam ntau. Qhov kev ua no tau pab txhawj xyuas cov kheej kub uas muaj kev nyuaj siab, kev nyuaj siab, thiab cov kheej kub uas muaj qhov kev sib sau ntau yam, thiab tau xaiv cov kev ua haujlwm tsaus siab rau kev tsim kho tshuaj tshiab, kev tsim kho tshuaj rau lub rooj, thiab kev tsim kho tshuaj tshiab.

Qhov kev ua haujlwm thiab qhov kev sau

Los ntawm kev xav txog kev koom haum ntawm kev hloov qhov chaw thiab kev ua haujlwm, cov CNC Wire EDM tshiab muaj qhov cuab yeej sib npaug rau lub cim ntawm ntau qhov chaw (xyuas li 4-axis X/Y/U/V sib npaug). Ntawd pab tau kev ua haujlwm ntawm kev hloov qhov chaw nrog kev ua haujlwm ntawm kev hloov qhov chaw uas muaj ntau qhov chaw thiab kev hloov qhov chaw uas muaj ntau qhov chaw. Los ntawm kev siv lub wire electrode thiab kev xaiv qhov chaw, cov khoom siv uas muaj nyob hauv lub tshuab no yog muaj peb qhov tswv yim tshwj xeeb:

Cov HS-WEDM : Siv lub molybdenum wire los ua lub electrode uas hloov qhov chaw nrog kev hloov qhov chaw ntau dua 8–12 m/s, cov khoom no muaj kev ua haujlwm zoo heev thiab muaj kev siv tau zoo heev, yog li cov khoom no tau siv dav rau kev hloov qhov chaw ntawm cov khoom siv thiab kev hloov qhov chaw ntawm cov khoom siv.

Cov MS-WEDM (Medium-Speed WEDM) : Tshuaj ntxiv kev kho tawm ntau yam (skimming) technology, kev kho tawm ntau yam uas muaj qhov siab thiab qhov siab ntawm kev kho tawm, thiab kev kho tawm uas muaj qhov siab thiab qhov siab ntawm kev kho tawm, MS-WEDM nyob rau hauv qhov siab thiab qhov siab ntawm kev kho tawm rau ±0.003–0.005 mm thiab ua kom qhov siab thiab qhov siab ntawm kev kho tawm rau Ra 0.6–0.8 μm. Yog li cas, nws yog qhov kev kho tawm uas muaj qhov siab thiab qhov siab ntawm kev kho tawm thiab qhov siab thiab qhov siab ntawm kev kho tawm.

Cov khoom siv WEDM uas kho tawm ntau yam (LS-WEDM / Slow-Speed WEDM ): Siv lub wire brass lossis lub wire uas muaj cov ntaub ntawv kho tawm uas kho tawm ntau yam thiab tsis kho tawm dua, LS-WEDM tau qhov siab thiab qhov siab ntawm kev kho tawm rau ±0.001 mm thiab qhov siab thiab qhov siab ntawm kev kho tawm rau Ra < 0.1 μm. Nws yog qhov khoom siv uas muaj qhov siab thiab qhov siab ntawm kev kho tawm thiab qhov siab thiab qhov siab ntawm kev kho tawm rau kev kho tawm ntau yam thiab kev kho tawm ntau yam.

Kev kho tawm thiab kev kho tawm uas muaj qhov siab thiab qhov siab ntawm kev kho tawm

Kev kho tawm uas muaj qhov siab thiab qhov siab ntawm kev kho tawm yog kev kho tawm uas muaj qhov siab thiab qhov siab ntawm kev kho tawm hauv qhov tsis muaj peb ntawm lub wire electrode thiab lub workpiece. Thaum muaj discharge, lub dielectric medium rov qab, ua cov discharge plasma channel uas muaj qhov ceev tshaj plaws hauv qhov kawg tau 10,000°C–12,000°C, uas txhawj nqa thiab sib thaj qhov ntau ntau ntawm lub workpiece surface. Thaum muaj pulse intervals, lub water-based dielectric fluids lossis deionized water uas muaj kev sib xyaw nyob rau hauv lub workpiece yuav tshem tawm cov debris uas tau rov qab thiab tshem tawm lub dielectric insulation thiab yuav tshem tawm qhov ceev.

Lub machining process no muaj cov qhov zoo tshaj plaws ntawm kev sib xyaw:

Zero Macroscopic Mechanical Cutting Force : Vim tias no yog lub process uas tsis sib txuas, nws tsis muaj kev sib txuas rau lub workpiece, uas yog qhov zoo rau cov khoom uas muaj qhov ntev thiab qhov ntev, micro-grids, thiab qhov ntev ntev.

Broad Material Adaptability : Lub workpiece machinability yog ib qho uas sib txuas rau lub electrical conductivity, tsis muaj kev sib txuas rau lub heat-treatment hardness, toughness, lossis melting point.

Exceptional Geometric Flexibility : Muab los ntawm kev siv cov lus qhia uas tswj hauv qhov kev txuas ntxiv, nws yuav tau kev kho tshem ntau yam khoom uas muaj qhov rooj (R-angles) me me, cov kho tshem uas tsis zoo, cov kho tshem me me, thiab cov kho tshem 3D uas muaj qhov ntev thiab qhov me me.

Cov kev siv hauv kev tsim khoom thiab qhov tseem ceeb tom ntej

Hauv cov kev tsim khoom rau lub zog tshwj xeeb, cov khoom CNC Wire EDM feeb li ua haujlwm rau hauv qhov sib sau rau cov khoom CNC milling, cov khoom machining centers, thiab cov khoom grinding. Nws tshwj xeeb nyob rau hauv kev kho tshem qhov kawg ntawm cov khoom uas muaj qhov ntev heev tom qab ua kom ntev, kev kho tshem rau cov khoom stamping thiab cov khoom plastic mold inserts, thiab kev tsim cov khoom carbide uas siv rau kev kho tshem.

Thiab mus rau hauv qhov kev tsim khoom ntawm lub ntiaj teb, kev tsim khoom yuav tsum yog ntau dua, ntau dua, thiab ntau dua rau kev siv cov lus qhia, kev siv wire EDM yuav tsum muaj kev npaj ntau dua thiab kev npaj ntau dua:

Kev tswj hauv kev kho tshem uas muaj kev paub: Kev sib koom ntawm kev siv lub tshuab ntsuas qhov kev tawg thiab kev siv cov databases ntawm cov neeg paub zoo tau pab rau kev sib koom ntawm kev siv lub tshuab thiab kev sib koom ntawm kev siv lub tshuab hauv qhov sib koom, thiab txog kev siv lub tshuab hauv qhov sib koom thiab kev siv lub tshuab hauv qhov sib koom, thiab txog kev siv lub tshuab hauv qhov sib koom thiab kev siv lub tshuab hauv qhov sib koom.

Kev siv lub tshuab thiab kev siv lub tshuab hauv qhov sib koom : Kev sib koom ntawm cov kev siv lub tshuab (AWT) thiab kev sib koom ntawm cov kev siv lub tshuab tau pab rau kev siv lub tshuab hauv qhov sib koom thiab kev siv lub tshuab hauv qhov sib koom.

Kev sib koom ntau dua : Kev sib koom ntau dua ntawm cov kev siv lub tshuab thiab cov CAD/CAM/IoT tau pab rau kev siv lub tshuab hauv qhov sib koom thiab kev siv lub tshuab hauv qhov sib koom, thiab txog kev siv lub tshuab hauv qhov sib koom thiab kev siv lub tshuab hauv qhov sib koom.

Qhov xav thiab qhov xav

Los ntawv tshuaj no yog qhov tseem ceeb rau kev kho mob tsis ua raws li kev kho mob tseem ceeb. CNC Wire EDM technology tsis yog tias nws tuaj yeem txhawj xyuam rau cov kheej xwm ntawm kev kho mob tseem ceeb, tab sis nws kuj muaj qhov tseem ceeb rau kev pab lub hom phiaj kho mob tseem ceeb los ntawm kev kho mob tseem ceeb, aerospace, thiab cov khoom siv rau kev kho mob. Ntawd mus, nrog rau kev txhawj xyuam ntau dua rau lub hauv paus ntawm kev kho mob tseem ceeb thiab cov hauv paus tswv yim, WEDM yuav pab kev kho mob tseem ceeb mus rau qhov zoo dua, siv ntau dua, thiab muaj kev kho mob tseem ceeb zoo dua.
