Txoj kev tsim cov khoom yas

Kev tsim cov khoom siv yas feem ntau suav nrog kev sib xyaw, molding, machining, sib koom, hloov kho thiab sib dhos ntawm cov yas. Plaub txheej txheem kawg yog ua tiav tom qab cov yas tau tsim rau hauv cov khoom tiav lossis cov khoom tiav ib nrab, tseem hu ua cov txheej txheem yas thib ob.

Lub molding ntawm cov khoom yas yog qhov txuas tseem ceeb ntawm kev ua cov yas. Ntau hom plastics (hmoov, pellets, kev daws teeb meem los yog dispersions) yog tsim rau hauv cov khoom los yog qhov khoob ntawm cov duab uas xav tau. Muaj ntau li peb caug hom molding txoj kev. Nws txoj kev xaiv yog txiav txim siab los ntawm hom yas (thermoplastic lossis thermoset), thawj daim ntawv, thiab cov duab thiab qhov loj ntawm cov khoom. Cov txheej txheem siv cov yas ua cov thermoplastics feem ntau muaj xws li extrusion, txhaj tshuaj molding, calendering, tshuab moulding thiab thermoforming, thiab lwm yam. Cov txheej txheem yas thermosetting yas feem ntau siv molding, hloov molding, thiab txhaj tshuaj molding. Lamination, molding thiab thermoforming yog cov shaping ntawm cov yas ntawm ib qho chaw tiaj tus. Cov txheej txheem ua cov yas saum toj no tuaj yeem siv rau kev ua cov roj hmab. Tsis tas li ntawd, muaj cov castings siv cov kua monomers lossis polymers ua raw khoom. Ntawm cov txheej txheem no, extrusion thiab txhaj tshuaj molding yog feem ntau siv thiab cov txheej txheem molding yooj yim tshaj plaws.

Kev siv tshuab ua cov khoom lag luam yas qiv nyiaj ua cov txheej txheem xws li hlau thiab ntoo los tsim cov khoom yas uas muaj qhov ntev heev lossis cov khoom me me, thiab tseem tuaj yeem siv los ua cov txheej txheem pabcuam rau kev tsim, xws li sawing ntawm extruded profiles. Vim tias qhov kev ua tau zoo ntawm cov yas sib txawv ntawm cov hlau thiab ntoo, cov yas tsis zoo thermal conductivity, thermal expansion coefficient thiab elastic modulus. Thaum lub fixture los yog cov cuab yeej yog pressurized ntau dhau lawm, nws yog ib qho yooj yim rau deformation, thiab nws yog ib qho yooj yim mus yaj thaum txiav, thiab nws yog ib qho yooj yim mus ua raws li cov cuab yeej. superior. Yog li ntawd, thaum cov yas yog machined, cov cuab yeej siv thiab cov kev txiav ceev yuav tsum tau yoog raws li cov yam ntxwv ntawm cov yas. Feem ntau siv machining txoj kev muaj xws li sawing, shearing, xuas nrig ntaus, tig, npaj, drilling, sib tsoo, polishing, threading, thiab lwm yam. Tsis tas li ntawd, cov yas tseem tuaj yeem ua laser txiav, xuas nrig ntaus thiab welded.

Kev koom tes hauv kev tsim cov khoom yas Cov txheej txheem ntawm kev koom nrog cov khoom yas hauv kev ua cov yas muaj xws li vuam thiab kev sib txuas. Cov txheej txheem vuam yog cov cua kub vuam siv lub tshuab electrode, kub yaj vuam siv lub tshuab hluav taws xob kub, thiab kev siv vuam ntau zaus, kev sib txhuam vuam, induction vuam, ultrasonic vuam, thiab lwm yam. Txoj kev sib khi tuaj yeem muab faib ua flux, resin tov thiab kub yaj nplaum nplaum raws li cov nplaum siv.

Lub hom phiaj ntawm kev hloov kho saum npoo ntawm cov khoom siv yas yog ua kom zoo nkauj ntawm cov khoom yas, uas feem ntau suav nrog: kev hloov kho tshuab, uas yog, kev siv cov ntaub ntawv, sib tsoo, polishing thiab lwm yam txheej txheem los tshem tawm burrs, burrs, thiab kho qhov loj me. ; Qhov saum npoo ntawm lub workpiece yog ci ntsa iab nrog cov kuab tshuaj, thiab qhov chaw ntawm cov khoom yog them nrog ib zaj duab xis qauv; daim ntawv thov xim, suav nrog xim pleev xim, luam ntawv thiab kub stamping; hlau plating, nrog rau lub tshuab nqus tsev txheej, electroplating thiab tshuaj lom neeg cov nyiaj plating, thiab lwm yam. Yas ua kub stamping yog hloov cov xim txhuas ntawv ci txheej (los yog lwm yam txheej txheej txheej) ntawm cov khoom kub stamping rau cov khoom nyob rau hauv tshav kub thiab siab. Ntau yam khoom siv hauv tsev, cov khoom siv hauv tsev, cov khoom siv niaj hnub, thiab lwm yam, siv cov qauv no kom tau txais cov qauv xws li cov hlau nplaum lossis ntoo grain.

Kev sib dhos ntawm cov khoom siv yas Kev lag luam ntawm kev sib sau ua tiav cov khoom yas rau hauv cov khoom tiav los ntawm cov txheej txheem xws li kev sib txuas, vuam thiab kev sib txuas tshuab. Piv txwv li: yas profiles, uas yog sib sau ua ke rau hauv yas qhov rais thav ntawv thiab cov qhov rooj yas tom qab sawing, vuam, drilling thiab lwm yam kauj ruam.
