Forging, Casting thiab CNC Machining

Musntaustej yam koj ua ib cov pwm tawm hlau zoo heev. Koj muab ib phaj ntawm qhov koj xav ntaus ntawm ob lub halves ntawm ib cov pwm hlau, thiab nyem cov pwm.NYUAJ!Xws li tom kaum tawm ntau (thiab ntau yam, 175,000) ntawm tons, los ntawm ib cov xovxwm uas tej zaum yuav outweigh rau koj lub tsev. (Moveable ib nrab ntawm cov pwm hu ua ib andquot; toolandquot; rau ib nrab hnub nyob ruaj ruaj yog hu ua andquot;die.andquot;)

Tus hlau tsev xws li cov tshuaj txhuam hniav, thiab thaum koj qhib cov pwm, koj muaj koj qhov. Me ntsis xov, thiab nws cov kev npaj yuav siv. Cov txheej txheem kim teeb (yog kim heev ua rau tuaj pwm, thiab cov xovxwm, thaum quite yooj yim, yog loj loj, thiab nqi kom haum), tiam sis yog koj ua ib yam dab tsi, nws yuav pheej yig heev. Lub pob ntawm hlau yuav tau txias (hlau qhab raws, 1/3 ntawm cov melting point) los kub (ze lub melting point, hais txog qhov kev xaiv yog hais tias koj xav ntaus hlau).

Yog lwm hom dabcasting(pouring kua hlau rau hauv ib cov pwm) thiabCNC (ComputerNumericCmachining ontrol).

Cov lusteb no feem ntau yog los ntawm forging. Ua hlau raus, nws tas andquot; grainsandquot;. Cov nplej yeej muaj zog, tab sis lawv donand #39; t andquot; stickandquot; sib txig. Yog li cov castings yuav zoo tawg, thiab yog koj saib tus so, nws yuav ua tau lub thawv andquot; matteandquot; nto, raws li nws yuav tau muab cais los ntawm cov nplej ntawd. Nyob rau hauv nqe lus metalurgists, nws qhia tsis ductility.

Thaum koj ntaus ib daim hlau, lub High School pressures andquot; collapsesandquot; Cov nplej ntawd. Tus no me ntsis denser, thiab yuav yuav nyom es lov. Nws yuav muaj zog heev dua ib casting, los yog tus zoo lawm tib hlais tawm ntawm ib pob ca cov hlau. Ntawm qhov chaw, vim nws muab cov loads ntau tshaj yog feem ntau yuav tus haum siab, thiab muaj zog koj yuav cuam tshuam no qhov chaw, cov tougher ib sab. Ntais ntuj actualy qhia haum ci iab nto, raws li qhov chaw ntawm lub andquot; grainsandquot; yog ploj mus. Uas txaus raws li lub hlau squeezed imparts lis qauv rau cov hlau uas ib ntsis zoo li cov ntoo, ua zog tuaj tshuam rau cov kev qhia. Tsim kom forging ciaj thiab xyuas tiv thaiv no ntws sij ua ib sab haum siab rau cov lus qhia uas nws yuav tsum tau tawg lossis dam nyob hauv.

Vuas hlau uas yuav muaj tau nrum, forged los yog kuav los tiag (squeezed ntawm chais, tsi muaj txwv forging, tsuas muaj peev uas ua tau tej yam tiaj tus uas ncaj lis zoo ib yam li lub Rooj Tswjhwm Saib cov).

Nws yog muab mus rau tus txheem haum tshuab cuab tam, uas nws tau txoj hauj lwm tsoov thiab motors ntawm cov tswj nqhuag ntsia. Qhov no yeej yog ib tug neeg hlau kws kho tshuab. Koj siv ib tug tej yam uas txiav tseg tag nrho cov hlau ntawd isnand #39; t koj crank. 3D hlau hauv qab daim tawv-a-sketch, nrog lub tshuab computer interpolating ces lub voj tawm nrhiav du zoo nkauj tuaj.

Muaj ob peb txog tej teeb meem no. Ua ntej tshaj, nws so ntau hlau. Cov khoom uas raug tshem tawm yog hlau cia li shavings, thiab yuav tsuas muab muag rau seem. Ntawm comparison, forging siv yuav luag tag nrho cov hlau, tsuas yog cov me me ntsis andquot; flashandquot; rau hauv speed lub cuab tam thiab tus tuag ntawd seeps. Txoj kev yuav muaj sij hawm haus mas tau — koj thiaj li yuav tshem tau ob peb nti hlau ib feeb sau lo lus teb. (txwv feem ntau los ntawm koj lub peev xwm kom cov txhuam ntawm tej los ntawm overheating, thiab tejzaum nws melting yam. Qhov no yog ib qho tseem ceeb rau tej cuab tam, uas tej zaum yuav loj tiv thaiv yog tias koj tau txais nws kub heev, never mind ze ze ntawm melting), ib feem uas yog andquot; sprawlingandquot; zoo li koj crank zoo, yuav noj 10 feeb los yog ntau dua ua, lub vib nas this uas nws yuav siv ib cov xovxwm rau cycle tsawg dua. (Ib xovxwm loj yuav ua ntau yam ib squish, muab tseem ntau dua productivity.)

Lawv yuav nyuab cav tov, servomechanisims, thiab xab tshuab uas tau ntsuas rau 0.005 hli (0.0001andquot;) thaum koj tau kev pab hauv roj puv. Ib lub tshuab CNC muaj tsawg kawg yog 6 motors (xws li ib co hloov cuab yeej, thiab ib lossis ntau tshaj rau tso roj thiab coolant ntau cov chaw). Qhov no translates khiav uas tej zaum yuav zoo nyob rau $1/ feeb. (Lub computer tsi muaj ib qho teeb meem loj txog tus nqi cuam.)

Huag muaj, muaj zog. Zoo, yog tias koj txiav tseg tau hlau, nws doesnand #39; t muaj lub packed nruj nreem deg tham rau qhov xaus ntawm ib forging. Loj tuaj lawm, tej zaum muaj nyob hauv cov fab uas muaj ib tug ntse hlws ris. Cov no yog andquot;kev nyuab siab risers, andquot; is tias kab nrib pleb yuav pib (nyob rau hauv cov hlau, tiam sis yog txhuas rhiab heev rau nws. Titanium yog tej zaum tseem phem tshaj ntawd.)

Koj canand #39; t siv ib tug neeg nyob rau hauv kaum sab xis ntawm lub forging, koj yeej yuav tau txais ib sab ntawm cov pwm. Vim li ntawd tag nrho sab ntawm cov ces kaum yuav tsum tau tshaj 90 degrees wider, thiab muaj radiused hau (yog hais tias koj muaj ib tug tuag (pwm) uas sim tau tsim ib tug ntse ces kaum, nws yuav txiav ntau dua li thawb cov hlau rau hauv qhov chaw.

CNC doesnand #39; t kom txwv zoo li no, tab sis yog yuav mus nicely radiused ntawm cov ces kaum, koj puas tau hloov cuab yeej, yuav ua rau cov hnub tshaj. (koj siv ib tug ca uas rhuav tshem ntawm tej qhov uas cov hlau nyob qhov chaw tiaj tus, thiab siv ib tug nosed hloov uas tsim hauv vojvoog qhov tsim nyog.) Yog li xakev nyuab siab riserstxhais tias kim kim machining lub sij hawm.

Yog vim licas thiaj li CNC kiag li? Thiab nws zoo nyob ua me tooj ntawm daim compicated. Qhov tseeb, lawv yuav yog qhov yuav ua rau tuaj pwm (hu ua lwm yam cuab yeej thiab xyuas) ua koj forging in. (vim li ntawd, siv tshuab CNC muaj tiag nws txo qis rau andquot; toolingandquot; cov nqi uas forging!) Nws tau txais nws cov biggest boost los ntawm tus missle folks. Yog hais tias koj tsuas npaj tsim 30 ntawm ib yam dab tsi, CNC yog qhov tshaj yog vim rau qhov muaj ib tug zoo nyuab, li ntawd landing iav strut rau ntawd fighter.

Txoj kev sib haum xeeb dividend tshuav ib Rev ntawm khw nrog CNC peev xwm ntau heev. Txij li tus nqi ntawm lub tshuab andquot; cia li zaum idleandquot; yuav tau yooj yim yuav ntau tshaj li ib nrab dab tsi nws nqi khiav puv tawm rau ib billable hauj lwm, nws tau pom ib yam dab tsi rau nws ua, los yog cov sij hawm thaum yuav tau hu rau lub auctioneer. Lawv nrum nyob ib ncig ntawm tej yam uas yuav tau tej nyiaj muab qhov nyiaj them rau daim ntawv xauj tsev. Qhov chaw tsheb tuam boutique thiab lwm yam, qhov twg andquot; scienceandquot foob pob ua ntxaij; ntxiv li cas tsis txaus txaus siab rau overcome CNCand #39; s inefficencies, muaj ib yam dab tsi uas cov khw mus rau latched. (rau lwm tus, los saib golf tej pab pawg los yog mototcycle thiab lub tsheb plhaw saum qhov chaw)

Xovxwm, thaum loj thiab hnyav yog ib tug yooj yim heev andquot; techandquot tsawg; tshuab, uas lawv yeej yuav tsum muaj tsawg kawg nkaus maintence. Rau qhov cov tshuab cov ruam thiab tawg. Nyuab tshaj plaws ib sab ntawm ib qhov xovxwm yog tus sensors uas yuav ua kom paub tseeb tias cov operatorand #39; s cev yog kev ua ntej nws pib mus. Itand #39; s yog ib zaug xwb tsav txuas nrog lub twj tso kua mis, thiab ib tug loj hydraulic piston, los yog ib andquot; forgeandquot nco qhia ib pob loj loj ntawm hlau, muaj ib mechanisim uas picks nws, thiab nws dauv. (CLANG!!!). Tsis muaj txoj kev zoo nkauj xab iav. Tsis muaj lub tshuab computer, yog lawv muaj ib tug neeg hlau ntawm mus thauj khoom thiab txo lub xeem lawm.

CNC yog ib tug tseem qhuas zoo mus forging kuv thiab. Muaj ntau ntau daim tias forging canand #39; t tsim. Internal threads, piv txwv li. Ces koj yuav noj koj nyoos forged crank VOJVOOS tawm hauv qhov xovxwm, ces muab tso rau hauv lub tshuab CNC coj mus rhaub lub qhov rau lub pedals, crank bolts puller thiab chainring. Kom paub meej, yog hais tias koj yeej yuav ua tau lawv nyob hauv lub tsheej lab, koj yuav cia li teeb lub tshuab yooj yim uas yuav tsuas tho thiab coj mus rhaub crank qhov.

Yog koj paub tias koj yuav tsum ua 50,000 ib xyoo ces nws yeej yuav yog 5 qhov rau ib lub vajvoog 110 hli, koj kev tus CNC mus ua tus fixture uas tuas daim 5 laum khoom rau cov vajvoog ntawd, thiab muaj lawv tig unison. Ntxiv ib ntsis nyob hauv nruab nrab lub geared los mus hlais cov puller threads, thiab # 7 rau xov rau qhov pedal. Nws sai dua lub computer (uas yuav ua ib los yog ob tug nyob qhov zuj zus, thiab yuav siv sij hawm mus nyob ib sab qhov chaw rau tus tom ntej qhov taub.) thiab muaj coob tseem khiav cheaper. Tej yuav siv lus tawm kev rau tus tswv sab, thiab muaj tseeb yuav ib de thiab muab lub cav uas nyob rau hauv stacking qhov chaw specializes. Nws isnand #39; t zoo meej, nws tsuas ua tau ntawd ib txoj haujlwm. Xav hloov voj ntsia liaj qhov rooj? Koj yuav tsum ua ib lub cav tshiab. Nws yuav muaj nqis rau kom changeable ces nws yuav ua 170and #39; s thiab 175and #39; s, tej zaum yuav zoo uas yuav cia li ua rau ob tug sib cav tov.

[Ua tau, kuv xav tias lawv feem ntau siv tus qub forgings/castings rau txhua crank lengths, yog hlais nyob lwm qhov, tshwj, kab tias super-top-of-the-kab ua qauv rau cov
