Leader Pins yog dab tsi?

Tau khiav ob- txoj haujlwm txhaj tshuaj tau txog kaum tsib xyoos tam sim no thiab tus thawj coj pins tseem ua rau mob taub hau ntau dua li qhov lawv yuav tsum tau ua. Cov txiv neej yuav siv sijhawm ntau lub lis piam hu rau hauv cov txheej txheem tsis ua haujlwm thiab tsis quav ntsej txog qhov tseeb tias lawv cov khoom siv kho vajtse raug tua.

Thawj tus pins ua ib txoj haujlwm. Lawv kab rau koj A- sab rau koj B- sab. Yooj yim. Tab sis nyob rau hauv ob- kev txhaj tshuaj ua haujlwm, koj tau txais ob txoj kab sib cais los txhawj xeeb, qee zaum peb yog tias koj tab tom khiav ib pawg teeb tsa. Mess up alignment ntawm ob lub interface thiab koj tab tom caum flash rau tag nrho cov khiav.

Cov hauv paus

Koj tus thawj coj tus pin tsuas yog ib qho tawv hlau dowel uas swb mus rau hauv lub bushing. DME thiab Hasco muag lawv los ntawm lub tsheb thauj khoom. Progressive Cheebtsam muaj lawv tus kheej kab. Feem ntau lub khw kuv tau ua haujlwm nrog standardize ntawm ib tus neeg muag khoom thiab lo nrog nws vim tias kev sib xyaw ua ke tsim teeb meem hauv txoj kev.

Standard teeb yog plaub tus pins ntawm cov ces kaum. Tus pin nias rau hauv ib lub phaj, lub bushing nias mus rau lwm qhov. Thaum cov pwm kaw, pins koom bushings thiab txhua kab. Ua haujlwm zoo rau ib qho - cov cuab yeej tua.

Ob - txhaj tshuaj sib txawv.

Yog vim li cas Ob-Tsov Txhaum Tej Yam

Hais tias koj tab tom khiav ib qho kev sib hloov platen teeb. Arburg thiab Engel tshuab ua qhov no ntau heev. Koj qhov chaw nruab nrab tig 180 degrees ntawm kev txhaj tshuaj. Qhov chaw nruab nrab xav tau nws tus kheej cov thawj coj pins ntawm ob lub ntsej muag.

Yog li tam sim no koj tau txais pins mus los ntawm koj lub phaj A - mus rau pem hauv ntej ntawm seem rotating. Thiab koj tau txais lwm cov txheej txheem los ntawm sab nraum qab ntawm qhov tig mus rau hauv koj lub phaj B-. Yim tus thawj coj pins yam tsawg kawg nkaus tsis yog plaub. Qee cov cuab yeej loj dua kaum ob.

Ntawm no yog cov khw muag khoom muaj teeb meem. Lub rotating seem yuav tsum index zoo tag nrho txhua lub voj voog. Yog tias koj cov pins ntawm qhov rotating seem tsis muab tso rau symmetrically nyob ib ncig ntawm lub axis rotation, lub cuab tam yuav tsis kaw tib txoj kev tom qab nws tig. Kuv pom ib lub khw hauv Grand Rapids sib ntaus qhov no tau ob lub lis piam ua ntej lawv pom tias lawv tus pin qauv yog 2 hli tawm -center.

Khoom siv thiab Specs

Feem ntau cov pins tuaj hauv 1.2767 lossis sib npaug cov cuab yeej hlau. Hasco siv lawv tus kheej qib proprietary tab sis nws zoo ib yam. Deg hardness khiav 58-62 HRC tom qab kev kho cua sov.

Rau sab bushing, koj muaj ob txoj kev xaiv. Bronze los yog hlau.

Bronze bushings yog ntau zam txim. AMPCO 18 lossis zoo sib xws alloys. Lawv tus kheej -lubricate rau qee qhov℃thiab lawv yuav zam me ntsis misalignment yam tsis muaj galling. Downside yog lawv hnav sai dua. Ntawm ob- txoj haujlwm txhaj tshuaj ua haujlwm peb zaug, Kuv tau pom bronze bushings mus oval nyob rau hauv qis dua 200K cycles.

Steel bushings kav ntev dua tab sis lawv xav tau roj thiab lawv xav tau kev sib raug zoo. Koj tsis tuaj yeem dag nrog hlau. Feem ntau Meusburger thiab MISUMI bushings yog hlau nrog cov roj grooves txiav hauv.

Tolerances Qhov Tseem Ceeb

Pin taub kam rau ua feem ntau yog h6. Bushing bore yog H7. Qhov ntawd muab rau koj qhov chaw ntawm kaum thiab peb caug microns tshem tawm ntawm 25mm tus pin. Suab nruj tab sis nws tsis nruj txaus rau qee qhov ob - ua haujlwm tua.

Qhov teeb meem yog thermal loj hlob. Koj cov pwm khiav ntawm tej zaum 80C ntawm thawj txhaj tshuaj thiab 60C ntawm qhov thib ob txhaj tshuaj. Los yog rov qab. Txawm li cas los xij, koj A- sab thiab B- sab yog loj hlob ntawm tus nqi sib txawv. Qhov h6 / H7 haum uas ua haujlwm zoo ntawm chav tsev kub yuav raug khi ntawm cov txheej txheem temp.

Kuv tau mus rau h5 / H6 haum rau ob peb txoj haujlwm kho mob qhov twg tus neeg siv khoom spec'd ± 0.05mm ntawm cov khoom siv. kim tab sis tsim nyog.

Runout ntawm tus pin tseem ceeb tshaj li cov neeg feem coob xav. Spec hais tias 5 microns max ntawm cov kabmob nto. Lub ntiaj teb tiag tiag, yog tias koj tshaj 8 microns koj yuav pom nws hauv qhov chaw. Tus pin wobbles thaum nws nkag mus rau hauv bushing thiab qhov wobble hloov txoj cai rau koj kab noj hniav sib dhos.

Fifth Pin Argument

Cov tsev kawm ntawv qub moldmakers hais plaub tus pins txaus. Lawv tsis yuam kev rau ib leeg - ua haujlwm txhaj tshuaj.

Ob - txhaj tshuaj sib txawv. Lub rotating seem flexes. Tshwj xeeb tshaj yog rau cov cuab yeej tshaj 500mm. Koj clamp cia nrog 300 tons thiab nruab nrab ntawm ntu ntawd deflects mus rau sab nozzle. Plaub kaum tus pins tsis tuaj yeem nres nws.

Ntxiv ib tug thib tsib tus pin tuag qhov chaw ntawm txoj kab parting pab. Tsis yog txhua tus ua nws. Progressive Components muag kev teeb tsa tshwj xeeb rau qhov no. Nws tsis pheej yig tab sis nws ua haujlwm.

Ib lub khw kuv tau sab laj rau yog khiav lub tsheb loj loj bezel. Ob -shoov mos- kov dhau nruj substrate. Lawv muaj flash ntawm lub interface ntawm txhua qhov chaw. Ntxiv ib tus pin nruab nrab thiab lub flash ploj lawm. Txuag lawv los ntawm scrapping lub cuab tam.

Installation Notes

Pins mus rau hauv txias. Lus. Dunk lawv hauv cov kua nitrogen los yog ntim rau hauv cov dej khov qhuav rau nees nkaum feeb. Tus pin shrinks, koj tso nws nyob rau hauv lub bore, nws sov thiab locks nyob rau hauv qhov chaw. Standard cuam tshuam yog 20-40 microns.

Tsis txhob hla cov kauj ruam nitrogen. Kuv twb saib hais mav sim nias pins nyob rau hauv chav tsev kub. Lawv tau qhab nia bore thiab ces koj tau txais tus pin uas yog xoob rau lub hlis tom qab.

Bushings nruab tib txoj kev. Qee tus txiv neej sov lub phaj es tsis txhob txias lub bushing. Ua haujlwm li cas. Tsuas yog tsis txhob ua ob qho tib si lossis koj yuav muaj kev tshem tawm ntau dhau thaum txhua yam normalizes.

Xyuas kom koj cov pins txuas mus dhau lub ntsej muag bushing thaum lub pwm raug kaw. Peb mus rau tsib millimeters. Qhov no tso cai rau koj kom pom qhov muag thaum koj tab tom teeb tsa lub cuab yeej. Yog tias koj tsis tuaj yeem pom tus pin tawm dhau los ntawm bushing, ib yam dab tsi tsis ncaj ncees lawm.

Hnav cov qauv los saib

Leader pins hnav nyob rau hauv txoj kev kwv yees. Qhov nkag chamfer rounds tawm ua ntej. Tom qab ntawd koj tau txais ib txoj hlua khi li 10mm rau hauv qhov chaw bearing qhov twg lub bushing di ncauj hu thaum qhib.

Ntsuas koj tus pins txhua txhua 100K cycles ntawm ob -shot tool. Siv lub micrometer, tsis yog calipers. Koj tab tom nrhiav txoj kab uas hla poob. Ntawm 25mm tus pin, 20 microns ntawm hnav txhais tau tias lub sijhawm hloov. Tsis txhob thawb nws. Hnav cov pins cia lub cuab yeej hloov thiab qhov kev hloov pauv ntawd zuj zus zuj zus txhua lub voj voog.

Galling yog lwm hom kev ua tsis tiav. Koj yuav pom nyiaj streaks ntawm tus pin nto. Txhais tau hais tias hlau yog hloov los ntawm bushing. Feem ntau tshwm sim thaum lubrication tsis ua hauj lwm los yog thaum muaj kab mob hauv lub bushing bore. Hloov ob yam khoom yog tias koj pom galling. Lub bushing bore puas lawm txawm tias nws zoo li.

Teeb meem ntiaj teb tiag

Tau ua haujlwm xyoo tas los. Ob- rab koob txhaj tshuaj rau lub chaw tsim khoom siv hluav taws xob. Rigid nylon substrate, TPE overmold. Cov cuab yeej yog hais txog 400K cycles nyob rau hauv thiab qhov chaw pib qhia phab ntsa thickness variation ntawm tuav seem.

Thawj qhov kev xav yog txheej txheem. Peb tweaked tuav siab, ntim lub sij hawm, txias. Tsis muaj dab tsi pab.

Rub lub cuab yeej thiab ntsuas tus thawj coj pins. Peb ntawm lawv zoo. Ib qho yog qis dua 35 microns. Lub bushing ntawm lub ces kaum tau ploj mus oval.

Dab tsi tshwm sim yog qhov chaw nres nkoj roj ntawm qhov bushing yog qhov tsis raug. Nws zaum nyob rau hauv ib lub hnab tshos uas tshem tawm cov ntaub ntawv sau. Kev tu tsis tuaj yeem tau roj nyob rau hauv qhov zoo. Lub ces kaum ntawd tau qhuav rau tej zaum 200K cycles.

Hloov tus pin thiab bushing, ntxuav tawm lub hnab tshos, repositioned roj haum. Teeb meem daws tau.

Point yog, tus thawj coj pin teeb meem tsis tas yuav tshwm sim li flash lossis luv luv txhaj tshuaj. Qee lub sij hawm lawv tshwm sim raws li qhov txawv txav uas zoo li qhov teeb meem txheej txheem.

Supplier Notes

DME yog tus qauv hauv North America. Cov khoom zoo, tsim nyog lub sijhawm ua haujlwm, txhua tus khaws lawv qhov ntau thiab tsawg. Lawv LP series npog feem ntau ob- daim ntawv thov txhaj tshuaj.

Hasco dominates nyob rau hauv cov teb chaws Europe. Zoo sib xws. Cov lej sib txawv. Yog tias koj tab tom tsim lub cuab yeej hauv lub teb chaws Yelemees thiab khiav hauv Ohio, xyuas kom koj tau txais cov khoom seem seem ntawm tes. Lawv tsis interchangeable.

Progressive Components ua qee yam khoom tshwj xeeb rau ob- ua haujlwm txhaj tshuaj. Lawv qhov chaw - kaw qhov system rau rotating platens yog tsim nyog saib yog tias koj tab tom tsim lub cuab yeej tshiab.

MISUMI thiab Meusburger ob leeg muaj cov ntawv teev lus dav dav nrog cov cuab yeej teeb tsa online zoo. Lub sij hawm ua cov hmoov txhuas tuaj yeem ntev rau qhov tsis yog - qhov loj me.

Tsis txhob pheej yig offshore pins. Kuv tau pom cov pins uas xav tias 58 HRC ntsuas ze dua 50. Lawv hnav nrawm thiab lawv tsis puag ncig pib nrog.

Kaw Xav

Leader pins tsis glamorous. Tsis muaj leej twg ncig koj lub khw thiab nug txog koj cov khoom siv kho kom haum. Tab sis lawv yog ib qho tseem ceeb rau kev ua ob- kev txhaj tshuaj. Tau txais cov specs txoj cai, nruab lawv kom raug, tswj lawv raws sijhawm, thiab lawv yuav khiav mus rau ib lab lub voj voog yam tsis muaj kev ua yeeb yam.

Hla ib qho ntawm qhov ntawd thiab koj yuav siv koj lub hnub los caum cov teeb meem uas zoo li txhua yam tshwj tsis yog hnav tus thawj coj pins.
