Bolt thiab txiv ntseej rau Track Khau Ntug Cov Menyuam Txiav Ntug
Cov txheej txheem ntau thiab tsawg rau excavator ntsia liaj qhov rooj thiab txiv ntseej yuav txawv nyob ntawm seb tus tsim thiab qauv ntawm lub excavator.Qhov ntau thiab tsawg muaj xws li M12, M16, M20, thiab M24.
Kauj Ruam 1: Kev tshuaj xyuas cov khoom raw & khaws cia
Raw khoom rau lub bolt yuav txiav txim siab raws li tus tsim qauv raws li kev thov.Cov khoom siv los kuaj xyuas thiab tom qab ntawd qhov chaw khaws cia kom raug txheeb xyuas kom tsis txhob muaj xeb thiab yuav tsum tau muab kev tiv thaiv zoo.
Kauj Ruam 2: Unthreaded / Unfinished bolt manufacturing
Feem ntau casting thiab forging yog siv nyob rau theem no.Lwm txoj kev kuj yuav siv tau:
1. Sintering
2. Prototyping (Rapid)
Kauj ruam 3: CNC machining
Tom qab ib feem tau raug tsim los ntawm forging / casting txoj kev, nws yog ces machined rau qhov yuav tsum tau qhov ntev feem ntau yog CNC.
Cov haujlwm ua raws li ntawm no yog: taw tes, tig, grooving.
Kauj Ruam 4: Kev kho cua sov
Kev kho cua sov yog ua tiav tom qab machining kom cov fasteners muaj zog.Kev ua haujlwm hardening & tempering yog ua raws.
Ua ntej, hardening yog ua li ntawd bolt yog rhuab mus rau ib tug kub ntawm 850-900 ° C thiab ces quenched nyob rau hauv lub txias media.
Qhov thib ob, lub ntsia liaj qhov rooj yog rov ua kom sov kom rov qab los ntawm qhov hnyav hnyav hnyav dua, kom lub ntsia liaj qhov rooj tseem muaj zog dua.Kev rov ua kom sov yog ua kom txo qis ntawm cov ntsia hlau uas tau tshwm sim thaum lub sijhawm hardening.
Kauj ruam 5: Nto tiav
Tom ntej no yog cov txheej txheem nto tiav.Feem ntau, kev sib tsoo txheej txheem yog nqa tawm los ua kom lub ntsej muag smoother raws li cov txheej txheem ua tiav.
Kauj Ruam 6: Xov Rolling
Tom qab ua tiav cov txheej txheem, xov dov yog ua tiav nrog ob tug tuag.Ib qho yog nyob ruaj ruaj thiab lwm qhov yog qhov txav txav uas ua rau lub zog ntawm cov bolts thiab cov ntaub ntawv xov.
Kauj Ruam 7: Txheej
Tom qab xov dov, bolts thiab ntsia hlau fasteners yog coated nyob rau hauv thiaj li yuav tiv thaiv xeb thiab corrosion.Ib qho piv txwv zoo ntawm bolt txheej yog geomet txheej hauv bolts uas yuav raug kuaj rau SST (Salt Spray Test) nyob ntawm seb muaj pes tsawg teev raws li tau teev tseg.
Machinery hu ua FISCHERSCOPE yog siv los txiav txim siab txheej thickness nrog rau lwm yam thickness ntsuas ntsuas xws li txheej thickness meter.
Kauj Ruam 8: Kev tshuaj xyuas rau daim ntawv, haum & ua haujlwm:
Tom qab tag nrho cov txheej txheem tau ua tiav, qhov kawg ntawm ntu mus rau kev tshuaj xyuas.Nws yuav tsum ntsib
1.Torque test, SST
2.Fitment nrog txiv ntseej
3.Impact zog (Impact charpy test)
4.Tensile lub zog kuaj (% elongation ntawm ntsia liaj qhov rooj)
5. Core hardness ntawm bolt
6. Txheej thickness
Dimensional soj ntsuam thiab lwm yam.
