Dab tsi yog Bismuth Tin

Qhov qis melting point alloy pwm nrog bismuth thiab tin tsawg melting point alloy ntsiab raws li lub ntsiab Cheebtsam thiab lub melting point ntawm txog 70 ~ 150 degree yog haum rau tsim ntau yam npog qhov chaw ntawm loj thiab nruab nrab loj. Lub sij hawm ua pwm yog li 6 ~ 8h. Tus nqi yog 60%~90% qis dua cov hlau pwm. Lub Hoobkas tsuas yog yuav tsum tau npaj cov txheej txheem hlau tsim nyog kom ua tau raws li kev tsim thiab kev xav tau ntawm ntau qhov chaw npog.

Daim duab 1 qhia ib daim duab schematic ntawm cov qauv ntawm ib tug raug forming tuag rau ib tug sab hauv kub cua siab dej - txias sib sib zog nqus daim npog npog. Ib feem nrog ob - dotted kab hauv daim duab 1 yog cov qauv 17, tseem hu ua cov qauv pwm, uas yog lub hauv paus rau molding. Nws cov duab yog roughly tib yam li lub workpiece yuav tsum tau tsim, tab sis nws thickness yuav tsum sib npaug zos rau cov pwm sib txawv ntawm lub forming pwm. Ntxiv cov phab ntsa sab hauv thiab sab nrauv rau kev sib cais tsim cov punches, tuag thiab hemming nets. Muaj cov qhov me me ntawm cov qauv, kom cov molten alloy ntws los ntawm sab nraud ntawm cov pwm mus rau hauv kab noj hniav ntawm cov pwm los ua ib qho punch. Cov qauv tuaj yeem ua tau los ntawm kev sib tsoo steel daim hlau, pasted nrog iav ntaub, los yog txawm pasted nrog ntawv pulp thiab ces coated nrog kub resistant kua nplaum.

Cov pwm feem ntau yog siv rau ntawm cov xovxwm tshwj xeeb. Vim tias cov ntsiab lus melting ntawm cov hlau yog tsawg heev, cov hlau tuaj yeem yaj los ntawm cov cua kub hauv lub pas dej molten ntawm cov pwm. Lub pas dej loj yog kom yaj thiab ua rau lub pas dej molloy nyob hauv lub pas dej loj hauv lub pas dej Moly ntxiv cov hlau rau lub ntsiab molten pas dej ua ke, yog li txhim kho qhov tseeb ntawm cov pwm casting thiab txhim kho pwm. Qhov ntom ntawm cov ntaub so ntswg. Tsis tas li ntawd, thaum lub molten alloy ntws los ntawm sab nraud ntawm cov qauv mus rau lub puab kab noj hniav, lub inflow ceev yuav nce los ntawm pressurizing, thiaj li yuav txo tau lub sij hawm casting. Muaj chav dej txias nyob ib ncig ntawm lub pas dej ua ke tseem ceeb, nws txoj haujlwm yog txhawm rau txhawm rau txhawm rau lub sijhawm sib zog ntawm cov hlau, txo lub sijhawm pwm ua, thiab tseem ua rau cov hlau quench thiab txhim kho cov hardness ntawm cov hlau. Cov ntsia hlau ntsia tau rau ntawm lub phaj convex thiab lub qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Cov yeeb nkab tso tawm yog nrum nrog cov pwm, thiab cov ejector muab tso rau tom qab pwm.

Lub phaj steel yog ntxiv rau lub concave tuag qhib ntawm pwm, vim hais tias thaum lub hau yog tsim, lub phaj ntawm lub concave tuag qhib yog loj deformed, ua rau hnyav hnyav rau lub concave tuag qhib, thiab ntxiv cov hlau phaj tuaj yeem txhim kho. kev pab cuam lub neej ntawm pwm. Steel inserts kuj tuaj yeem muab ntxiv rau qhov chaw uas cov pwm hnav hnyav dua los txhim kho lub neej kev pabcuam.

Rau npog nrog nkhaus flanges, qhov no concave tuag lub qhov ncauj tsis tas yuav ntxiv steel daim hlau, thiab yog ncaj qha nrum los ntawm qis - melting alloys, thiaj li yuav txo tau tus nqi ntawm molding, tab sis cov kev pab cuam lub neej yog tsawg.

Siv lub pas dej molten los ua lub hau npog tsim tuag, tsuav yog qhov loj ntawm lub workpiece nyob rau hauv qhov loj ntawm lub pas dej molten, cov qauv tuaj yeem raug cam, yog li lub pas dej molten yog universal, thiab kho phaj ntawm cov punch thiab lub hnab ntim khoob kuj tuaj yeem ua tau thoob ntiaj teb, tsuas yog yog tias tsim nyog Cov hlau ntxig yog nplooj siab, yog li cov pwm - ua lub voj voog luv luv thiab tus nqi qis heev. Tom qab ib khub pwm siv, pwm tshiab tuaj yeem nrum, thiab tsuas yog cov qauv yuav tsum tau txais kev cawmdim, yog li qhov chaw cia me me.

Vim yog qhov qis melting point ntawm cov hlau, cov pwm tuaj yeem muab pov rau ntawm ib lub xovxwm, tshem tawm qhov yuav tsum tau rov nruab thiab kho cov pwm. Tus kheej - casting tuag presses tau tsim thiab siv nyob rau hauv tsev thiab txawv teb chaws, thiab cov xovxwm no nws tus kheej yog nruab nrog ib tug molten pas dej ua ke ntawm tsawg melting point alloys. Rau ib tus neeg hnav pwm qhov chaw lossis qhov tsis zoo ntawm cov pwm pwm, cov hlau fused zoo tib yam tuaj yeem kho tau, thiab cov hlau yog mos heev, yog li qhov saum npoo ntawm lub workpiece yuav tsis raug khawb thaum lub hau tsim.
