Koj paub ntau npaum li cas txog txoj kev ua cov xov hauv CNC machining?
Hauv CNC machining, threads feem ntau yog tsim los ntawm kev txiav lossis kev ua haujlwm. Nov yog ob peb txoj hauv kev siv xov ntau los ntawm pab pawg Anebon:
Tapping:Txoj kev no suav nrog kev txiav cov xov uas siv cov kais dej, uas yog cov cuab yeej nrog helical grooves. Tapping tuaj yeem ua tau los ntawm tes lossis siv lub tshuab, thiab nws yog qhov tsim nyog rau kev tsim cov xov sab hauv.
Xov Milling: Xov milling siv lub cuab yeej tig nrog ntau lub tshuab raj los tsim cov xov. Nws yog ib tug ntau yam txoj kev uas yuav siv tau rau ob sab hauv thiab sab nraud threads. Xov milling feem ntau nyiam rau cov xov loj dua lossis thaum muaj ntau yam xov ntau thiab ntau hom xav tau.
Xov Tig:Txoj kev no suav nrog kev siv ib qho kev txiav cov cuab yeej txuas rau ntawm lub tshuab dhos los tsim cov xov sab nraud. Xov tig yog feem ntau siv rau cov xov loj lossis ntev thiab haum rau ob qho tib si ncaj thiab tapered threads.
Xov Rolling:Nyob rau hauv xov dov, ib tug hardened steel tuag siv siab rau lub workpiece kom deform cov khoom thiab tsim cov threads. Txoj kev no yog qhov ua tau zoo thiab tsim cov xov zoo zoo, ua rau nws tsim nyog rau cov khoom ntim siab.
Xov sib tsoo:Xov sib tsoo yog txheej txheem machining precision uas siv lub log sib tsoo los tsim cov xov. Nws yog feem ntau ua hauj lwm rau high-precision thiab high-zoo xov ntau lawm, tshwj xeeb tshaj yog rau complex los yog tshwj xeeb threads.
Thaum xaiv cov txheej txheem xov, yam xws li xov loj, qhov yuav tsum tau muaj tseeb, cov khoom siv, ntim ntau lawm, thiab cov nqi txiav txim siab yuav tsum raug coj mus rau hauv tus account.
Keeb kwm
Lo lus Askiv sib raug rau cov ntsia hlau yog Screw. Lub ntsiab lus ntawm lo lus no tau hloov ntau ntau hauv ntau pua xyoo dhau los. Tsawg kawg hauv xyoo 1725, nws txhais tau tias "kev sib raug zoo".
Daim ntawv thov ntawm txoj cai xov tuaj yeem taug qab rov qab mus rau lub tshuab nqa dej uas tsim los ntawm Greek kws tshawb fawb Archimedes hauv 220 BC.
Nyob rau hauv lub xyoo pua 4th AD, lub teb chaws raws ntug dej hiav txwv Mediterranean pib siv lub hauv paus ntsiab lus ntawm bolts thiab ceev rau presses siv rau brewing cawu cub. Nyob rau lub sijhawm ntawd, cov xov sab nraud tau muab qhwv nrog hlua rau ib lub cylindrical bar, thiab tom qab ntawd kos raws li lub cim no, thaum cov xov sab hauv feem ntau yog tsim los ntawm hammering ib ncig ntawm cov xov sab nraud nrog cov ntaub ntawv softer.
Nyob ib ncig ntawm 1500, nyob rau hauv cov duab kos duab ntawm cov xov ua cov cuab yeej kos los ntawm Italian Leonardo da Vinci, twb muaj lub tswv yim ntawm kev siv cov poj niam cov ntsia hlau thiab cov iav pauv los ua cov xov sib txawv. Txij thaum ntawd los, txoj kev ntawm mechanically txiav threads tau tsim nyob rau hauv European watchmaking kev lag luam.
Xyoo 1760, cov kwv tij Askiv Askiv J. Wyatt thiab W. Wyatt tau txais daim ntawv pov thawj rau kev txiav ntoo ntsia hlau nrog cov cuab yeej tshwj xeeb. Xyoo 1778, British J. Ramsden ib zaug tau tsim cov xov txiav cov cuab yeej uas tau tsav los ntawm tus cab iav khub, uas tuaj yeem ua cov xov ntev nrog kev ua haujlwm siab. Xyoo 1797, British H. Mozley tau siv tus poj niam ua cov ntsia hlau thiab cov iav sib hloov los tig cov xov hlau nrog cov pitches sib txawv ntawm lub tshuab dhos tau txhim kho los ntawm nws, thiab tsim cov txheej txheem ntawm kev xa xov.
Hauv xyoo 1820, Maudsley tau tsim thawj pawg ntawm cov kais dej thiab tuag rau kev ua xov.
Thaum pib ntawm lub xyoo pua 20th, txoj kev loj hlob ntawm kev lag luam tsheb txuas ntxiv txhawb cov txheej txheem ntawm cov xov thiab kev txhim kho ntawm ntau yam kev ua tiav thiab kev ua haujlwm zoo. Ntau yam tsis siv neeg qhib tuag hau thiab tsis siv neeg shrinking kais tau tsim ib qho tom qab, thiab xov milling pib siv.
Nyob rau hauv thaum ntxov 1930s, xov sib tsoo tshwm sim.
Txawm hais tias cov xov rolling tshuab tau patented nyob rau hauv thaum ntxov 19th caug xyoo, vim hais tias muaj teeb meem nyob rau hauv pwm manufacturing, txoj kev loj hlob qeeb heev. Nws tsis yog txog thaum Tsov Rog Thoob Ntiaj Teb thib Ob (1942-1945) vim tias qhov kev xav tau ntawm kev tsim cov foob pob hluav taws thiab kev tsim cov xov sib tsoo tshuab, qhov teeb meem tau daws. Qhov teeb meem precision ntawm kev tsim pwm tau ua tiav txoj kev loj hlob sai.
