Tshaj tawm rau 2019-01-11Peb qhov kev lag luam, ib qho kev tswj hwm thiab ob qho kev ua tau zoo muaj feem cuam tshuam yog cov neeg tsim khoom ntawm fasteners, clips thiab lwm yam me me stampings los txiav txim siab txog kev siv dip spin txheej tshuab.
Ua ntej, ib puag ncig regulators tseem tsom ntsoov rau lawv cov xim ntawm plating.Qhov thib ob, tus naj npawb thiab ntim ntawm daim ntawv thov uas xav tau cov txheej txheem siab ntawm cov tshuaj tsuag ntsev, Kesternich ntsuam xyuas thiab kev sib tw torque yog nce.Siv lub dip spin txheej hla nyias zinc phaj los encapsulate zinc yog cov lus teb uas ua tau zoo thiab raug nqi.Cov txiaj ntsig ntawm kev ntsuas ntsev ntsev tuaj yeem txhawb nqa los ntawm 120 mus rau 1,000 teev siv txoj kev no.Nws kuj yog qhov zoo dua rau feem ntau cov kev xaiv los ntawm ib puag ncig kev xav.Thaum kawg, hydrogen embrittlement yog ib qho kev txhawj xeeb tsis tu ncua, thiab dip / spin tau pom tias muaj peev xwm txo qis lossis tshem tawm qhov teeb meem no.
Dip spin yog txheej txheem uas cov khoom tau muab tso rau hauv lub pob tawb mesh, submerged hauv txheej txheej thiab spun kom tshem tawm cov txheej dhau.Qhov kub thiab viscosity ntawm txheej, immersion lub sij hawm, kiv kev taw qhia thiab velocities thiab kho txoj kev yog ib tug ntawm cov variables uas tso cai rau cov neeg siv los customize ib tug txheej txheem daim ntawv qhia thiab ua tiav cov txiaj ntsig zoo, rov ua dua.
Kuj tseem ceeb yog dip / spin lub peev xwm los txo tus nqi ntawm ob qho tib si txheej thiab pov tseg pov tseg.Qhov no yog vim lub tshuab 98 pct lossis ntau dua ntawm qhov nruab nrab hloov pauv kev ua haujlwm.
Dip spin systems xws li cov tsim los ntawm Spring Tools, Portage, Michigan, yog qhov zoo tshaj plaws rau qhov me me nrog qee qhov contours nrog rau cov uas tuaj yeem coated hauv ntau yam tsis muaj kev sib koom ua ke.Thiab thaum muaj qhov tshwj xeeb tshwj xeeb (ib lub chaw tsim khoom fastener fixtures nws cov bolts loj tshaj plaws rau dip / spin processing), cov txheej txheem zoo tshaj plaws tau pom zoo nrog cov khoom uas yog 10 ntiv tes lossis ntev dua thiab tsawg dua ob ntiv tes hauv txoj kab uas hla.
Thaum lub tshuab ntxhua khaub ncaws thiab lwm cov khoom siv tiaj tus tau zoo dua coated nrog lwm cov tswv yim, dip / spin yog qhov tsim nyog rau vov tsev thiab lwm yam kev tsim kho fasteners, clamps, springs, o-rings, u-bolts, ntsia hlau thiab screws, motor mounts thiab ntau lwm yam khoom siv. rau mechanical finishing.
Dip spin technology yog sib xws nrog txhua yam loj coatings hom siv nyob rau hauv fastener xov;tshwj xeeb, txheej txheej uas sib xyaw ua ke muaj kev ua haujlwm siab rau tshuaj thiab galvanic / bi-metallic corrosion nrog UV stability, anti-galling zog thiab / lossis cov yam ntxwv tiv thaiv kev vibration.Feem ntau kuj yuav sib haum nrog sealants, nplaum thiab xauv thaj ua rau thaj thiab yuav qhuav rau qhov kov thaum kho.Cov txheej txheej tshwj xeeb muaj xws li fluorocarbons, zinc-nplua nuj, ceramic metallics (aluminium-raws li cov organic lossis inorganic topcoats) thiab cov tshuab dej.
Cov txheej txheem dip spin encompasses peb kauj ruam: 1) Ntxuav thiab pretreatment;2) Coatings daim ntawv thov;thiab 3) Kho.Fastener manufacturers feem ntau siv grit ntawm 80- mus rau 100-mesh txhuas oxide kom tshem tawm oxides thiab kho cua sov teev.Micro-, nruab nrab-los yog hnyav-crystalline zinc phosphate yog qhov kev nyiam ua ntej qhov xav tau, txawm hais tias muaj ntau lub dip / spin coatings uas tuaj yeem siv rau cov hlau liab qab.
Tom qab ziab, cov khoom yog thauj mus rau hauv ib lub tawb xaim-mesh lined pob tawb.Yog tias kev thauj khoom tsis siv neeg, lub kaw lus xa cov khoom mus rau qhov hnyav hopper nrog pre-set batch luj.Tom qab thauj khoom, cov khoom raug xa mus rau hauv lub dip / spin chamber thiab mus rau lub rotating spin platform uas lawv tau xauv rau hauv qhov chaw.Lub thawv txheej, muab tso ncaj qha rau hauv qab, yog tom qab ntawd tsa kom nkag mus rau lub pob tawb ntawm qhov chaw hauv txheej txheej.
Thaum lub sij hawm immersion tiav, lub thawv txheej poob mus rau qhov chaw uas lub pob tawb tseem nyob hauv lub thawv, tab sis siab dua cov kua theem.Lub pob tawb ces centrifuged.
Ib lub voj voog sib txawv yuav yog ib qho kev taw qhia rau 20 mus rau 30 sec, nres tag nrho, ces rov qab tig rau lub sijhawm sib npaug.Lub braking action re-orients qhov chaw kom zoo tshaj plaws tshem tawm cov coatings los ntawm recesses.Thaum dip/spin tiav lawm, lub nkoj txheej yog tag nrho qis thiab lub pob tawb rov qab, xauv thiab tshem tawm.Re-loading tshwm sim thiab cov txheej txheem rov ua dua.
Cov khoom siv txheej yog muab tso rau hauv lub nkoj steel thiab ntxig thiab tshem tawm los ntawm lub qhov rooj nkag.Cov xim hloov tau ua tiav hauv 10 mus rau 15 feeb los ntawm kev tshem tawm cov txheej txheem qub thiab pob tawb thiab hloov lawv nrog cov tshiab.Cov coatings yog khaws cia rau hauv lub dip / spin thawv, uas yog kaw nrog lub hau hlau los yog polyethylene.Mesh baskets yog ntxuav siv cov kuab tshuaj los yog grit moj tej tawg los yog lub mesh liner ib leeg yog ua tiav nyob rau hauv ib tug burn-off qhov cub.
Ob peb coatings siv nyob rau hauv fastener finishing cua-qhuav.Rau 90 pct ntxiv uas yuav tsum tau cua sov, me me dip/spin kab sib txuas ib lub qhov cub;Cov khoom siv loj dua suav nrog lub qhov cub siv conveyorized.Conveyor siv yog me me rau qhov chaw.Coated qhov chaw yog loaded ncaj qha mus rau lub qhov cub siv thiab kis manually hla lub dav.Los yog, lawv raug tshem tawm mus rau lub tais vibratory uas qhov chaw hla lub qhov cub siv tau.
Kho cov voj voog ntawm tsib mus rau 30 min;Qhov zoo tshaj plaws ncov hlau kub yog 149 txog 316F.Lub chaw tso cua txias ua kom cov khoom kub rov qab mus rau ze ze ntawm qhov chaw.
Dip spin cov cuab yeej yog tsim nyob rau hauv qhov ntau thiab tsawg scaled rau cov txheej txheem yuav tsum tau.Qhov twg cov khoom batch me me thiab ntau xim yuav tsum tau hloov, ib tug me me system, nrog ib tug 10-nti kab uas hla pob tawb, ib tug 750 lb / hr muaj peev xwm thiab rotational speeds ntawm xoom mus rau 900 rpm yuav pom zoo.Hom kab ke no yuav ua kom haum rau kev ua haujlwm ntawm phau ntawv, qhov twg tus neeg teb xov tooj thauj khoom lub pob tawb thiab ua haujlwm ntawm qhov poob thiab tig ntawm cov voj voog uas siv tes li qub lossis ib nrab automation qhov chaw thau khoom / tshem tawm yog phau ntawv, tab sis cov voj voog yog PLC tswj.
Lub tshuab nruab nrab, tsim nyog rau feem ntau cov khw muag khoom siv lub pob tawb 16 ntiv hauv txoj kab uas hla nrog lub ntim siv tau ntawm ib cu ft. Lub peev xwm yog kwv yees li 150 lbs.Cov kab ke no feem ntau yuav ua tiav txog 4,000 lbs / hr ntawm cov khoom lag luam thiab qhov nrawm nrawm txog 450 rpm.
Cov tuam txhab loj tshaj plaws thiab cov khw muag khoom ua tiav feem ntau tau txais kev pabcuam zoo tshaj plaws nrog lub kaw lus siv lub pob tawb 24-inch inch thiab muaj qhov nrawm nrawm txog li 400 rpm.
