Kev puas tsuaj rau txoj hauj lwm tawm tsam
Nws tshwm sim thaum lub zog ntawm cov khoom siv raw tsis txaus lossis muaj cov impurities ntawm cov hydraulic rauj piston thiab chisel. Qhov tshwm sim no tsis tshwm sim hauv ib lub sijhawm lossis lub sijhawm luv luv. Cov me me me me impurities tshwm sim ntawm piston thiab sab saum toj ntawm chisel thiab sab saum toj ntawm chisel yuav tawg me ntsis los yog tawg. Tom qab multipe tshuab, qhov tseeb qhov chaw yuav kis tau. Tus neeg siv yuav tsum tau ua tib zoo saib xyuas cov kev ua haujlwm kom tsis txhob muaj qhov xwm txheej tsis zoo thiab tsis txhob ua qhov tsis tsim nyog rau lub breaker. Qhov ntev ntev ntawm lub chisel yog 10% ntawm tag nrho qhov ntev.
Kev puas tsuaj rau txoj hauj lwm tawm tsam
Thaum cov ntaub ntawv muaj qee yam mob xws li tawg me me, qhov tshwm sim hauv daim duab yuav tshwm sim. Txoj haujlwm tawm tsam tuaj yeem tawg tam sim ntawd, tshwj xeeb tshaj yog thaum lub piston muaj kev cuam tshuam ntau dua. Yog tias tus neeg teb xov tooj txuas ntxiv siv, cov chisel nyob rau hauv lub breaker yuav ua rau lub piston puas. Qhov teeb meem no yog cov teeb meem raw khoom thiab peb tuaj yeem muab cov nyiaj them poob haujlwm.
01
Deflaction
Thaum cov khoom siv ntawm cov pob zeb tawg, xws li cov pob zeb tawg thiab cov piston tau laus thiab tsis zoo, lub chisel ib txwm tsis tuaj yeem khaws txoj haujlwm qub tom qab kev teeb tsa, uas ua rau kev sib cuag tsis tiav ntawm piston thiab txoj haujlwm tawm tsam thiab deflaction yuav tshwm sim. Tus neeg teb xov tooj yuav tsum tau xyuam xim rau kev tiv thaiv txhua hnub thiab hloov cov khoom qub qub los yog tatty hauv lub sijhawm. Tsis tas li ntawd, kev deflation loj tshwm sim los ntawm tib neeg kev ua haujlwm kuj tuaj yeem ua rau muaj teeb meem zoo sib xws. Peb yuav tsis them nyiaj yog tias qhov deflaction yog tshwm sim los ntawm kev laus ntawm cov khoom siv lossis kev ua haujlwm ntawm tib neeg.
02
Blank firing
Kev tua hluav taws kub yog qhov tshwm sim ntawm tus neeg teb xov tooj siv tsis tau zoo lossis tsis muaj kev xav. Tus neeg teb xov tooj yuav tsum nrhiav qhov teeb meem thiab daws nws, polish qhov chaw puas rau lawv tus kheej. Txwv tsis pub, cov hlau ntog tuaj yeem txav mus rau qhov sib txawv ntawm lub chisel thiab lub hav txwv yeem ntawm lub tshuab tawg kom txog thaum ua rau lub piston thiab chisel sib tsoo, ua rau ob qho tib si tawm tsam ntawm lub chisel thiab piston ob qho kev puas tsuaj. Peb tsis tuaj yeem muab nyiaj them rau qhov xwm txheej zoo li no.
Chisel flat sheath yog tawg
Yog tias cov khoom siv raw muaj qhov tsis ruaj tsis khov, qee qhov microcracks pom ntawm qhov muag liab qab tuaj yeem tshwm sim rau saum npoo ntawm chisel. Kev puas tsuaj ntawm microcracks yuav pom thaum siv tom qab kev kho cua sov. Feem ntau cov pob txha uas tshwm sim los ntawm qhov laj thawj no zoo nkauj heev, ib yam li kev txiav. Kev them nyiaj yug muaj nyob rau hauv cov xwm txheej zoo li no.
Raw khoom defect
Muaj qhov tsis zoo hauv cov khoom siv, thiab lub tshuab nqus tsev degassing thaum lub sijhawm ua haujlwm tsis zoo, uas yuav ua rau muaj npuas hauv cov khoom. Cov ntaub ntawv zoo li no tawg raws li qhov chaw uas muaj roj nyob tom qab kev kho cua sov thiab cov chisel yog ib qho yooj yim tawg zoo li txiav. Cov xwm txheej zoo li no yog cov khoom siv tsis raug thiab peb tuaj yeem muab cov nyiaj them poob haujlwm.
Kev ua haujlwm chisel
Thaum lub chisel tawg mus rau hauv ob halves, txhua ntawm ob daim muaj ib tug pom tseeb concave thiab convex nto, thiab muaj ib tug pom tseeb tawg nyob rau hauv lub pob txha pib taw tes rau ntawm pob txha tawg. Qhov no yog tshwm sim los ntawm kev ua haujlwm tsis tu ncua, kev ua haujlwm oblique thiab rub ua haujlwm. Lub chisel tau raug kev nyuaj siab loj rau ntawm qhov chaw uas nyob ib sab nrog cov khoom lossis cov khoom tawg, uas zoo heev tshaj qhov kev ntxhov siab uas cov chisel tuaj yeem nkag siab. Qhov kev taw qhia ntawm qhov tawg no yuav luag zoo ib yam li lub tiaj tiaj tiaj. Kev them nyiaj tsis muaj nyob hauv qhov no. Tus neeg teb xov tooj yuav tsum manipulate normatively.
Kev ua haujlwm chisel
Lub chisel tau tawg mus rau hauv peb daim, ob daim muaj concave nto, thiab lwm yam muaj ib tug tsis xwm yeem daim duab peb sab. Qhov laj thawj yog vim li cas chisel tawg yog cov chisel tau nkag mus tob rau hauv cov khoom thiab ces swings rov qab thiab tawm mus. Lub chisel tau raug kev nyuaj siab loj rau ntawm qhov chaw uas nyob ib sab nrog cov khoom lossis cov khoom tawg, uas zoo heev tshaj qhov kev ntxhov siab uas cov chisel tuaj yeem nkag siab. Qhov kev taw qhia ntawm qhov tawg no yuav luag zoo ib yam li lub tiaj tiaj tiaj. Kev them nyiaj tsis muaj nyob hauv qhov no. Tus neeg teb xov tooj yuav tsum manipulate normatively.
Khob hau
Ntsis hardness ntawm chisel yog siab, yog li thaum pib siv, thov tsis txhob siv nrog lub zog loj los yog ncaj qha rau ntawm cov pob zeb nyuaj thiab lwm qhov chaw. Ua ntej ua haujlwm lub chisel tshiab yuav tsum tau preheated nrog lub zog me me. Thiab cov chisel ua haujlwm ib txwm tom qab nws hloov mus rau kev ua haujlwm, ib yam li cov neeg ua haujlwm. Yog li chisel tuaj yeem ua nws qhov kev siv zog loj tshaj plaws. Tsis tas li ntawd, thaum crushing reinforced pob zeb lug, qhov tshwm sim no kuj yuav tshwm sim ces lub ntsis ntawm lub chisel yog daig rau hauv lub steel rebar. Tom qab ntawd peb tsis tuaj yeem muab cov nyiaj them poob haujlwm, thov daws cov lus qhia ua ntej siv.
Tswv yim forging teeb meem
DNG chisels yog tsim thiab tsim rau kev ua haujlwm hydraulic. Tus neeg teb xov tooj yuav tsum hloov lawv raws sijhawm. Random thiab ntau dhau forging ntawm chisel yuav ua rau muaj kev ntxhov siab ntau dhau ntawm txoj haujlwm tawm tsam thiab ua rau hnav. Peb tsis tuaj yeem muab nyiaj them rau qhov teeb meem no. Yog tias koj xav tau tshwj xeeb, thov qhia rau peb ua ntej booking.
Mushrooming zoo li
Tsis txhob tawm tsam tib qhov chaw ntau dua 30 vib nas this. Kev sib tsoo ntau dhau yuav ua rau muaj cua sov ntau dhau ntawm kev ua haujlwm, thiab tuaj yeem ua rau muaj kev puas tsuaj xws li "mushrooming" zoo li.Yog tias cov khoom tsis tawg tom qab lub sij hawm ntev hitting, thov hloov qhov hitting point. Kev them nyiaj tsis tuaj yeem muab los ntawm peb tawm tsam qhov tshwm sim no, thov ua qhov ntse thiab siv txuas ntxiv mus.
Khoov chisel
Thaum cov neeg siv ua qhov tsis sib xws los yog rub ua haujlwm, cov chisel uas muaj qhov tawv tawv yog yooj yim tawg. Tab sis yog hais tias lub hardness ntawm chisel tsis txaus, ces nws tseem muaj toughness, uas ua rau khoov. Feem ntau cov kev taw qhia bending yog tib yam li cov kev taw qhia tiaj tus sheath. Cov khoom warping tshwm sim los ntawm kev kho cua sov tsis txaus tuaj yeem tau txais cov nyiaj them poob haujlwm.
Chisel tawg
Nws belongs rau pom tseeb raw khoom zoo teeb meem. DNG chisel siv cov hlau zoo ntxiv thiab ua kom nruj zoo tswj cov khoom siv raw. Peb sim peb qhov zoo tshaj plaws kom tsis txhob muaj qhov tshwm sim no, thov koj xav siv.
