Thaum npaj lub caij nplooj ntoos hlav hlau kos duab ntau lawm kab, tus yuam sij yog kom meej meej qhia koj cov khoom muag (xws li lub hom phiaj hlau txoj kab uas hla thiab lub hom phiaj ntawm lub caij nplooj ntoos hlav), uas ncaj qha txiav txim seb yam khoom thiab cov txheej txheem yuav tsum tau. Nyob rau tib lub sijhawm, nws yog ib qho tseem ceeb kom nrhiav tau qhov sib npaug ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig (xws li kev kho cov dej khib nyiab) thiab kev txhim kho qib ntawm automation, uas tuaj yeem txhim kho kev tsim khoom thiab kev tsim nyog tus nqi.
🔧 Kev tshuaj xyuas cov txheej txheem tseem ceeb thiab cov cuab yeej siv
Raw Khoom Pretreatment:Hlau rods feem ntau muaj cov nplai ntawm lawv qhov chaw, uas yuav tsum tau tshem tawm los ntawm kev tshem tawm cov xeb (xws li, shelling) los yog tshuaj tua kab. Phosphating thiab saponification kev kho mob ces tsim ib txheej lubricating ntawm cov hlau nto kom txo tau kev sib txhuam thaum kos duab. Piv txwv li, qhov siab - cov dej yaug siab tsis pub tsawg dua 0.60 MPa tau pom zoo tom qab phosphating.
Hlau Drawing:Qhov no yog cov kauj ruam tseem ceeb thiab yog ua nyob rau hauv cov theem raws li lub hom phiaj hlau txoj kab uas hla:
Rough Drawing/Intermediate Drawing: Feem ntau, ib tug ncaj- kab los yog pulley- hom kos duab tshuab yog siv los kos cov hlau los ntawm txoj kab uas hla loj (piv txwv li, 6.5 mm) mus rau qhov nruab nrab loj (piv txwv li, 5.0 mm).
Kev kos duab tiav:Txhawm rau ua kom tiav qhov ntev kawg nkaus (piv txwv li, φ2.5mm lossis finer) thiab zoo heev saum npoo, siv lub tshuab ncaj- kab tiav los yog dej-txias hlau kos duab tshuab. Cov theem no yuav tsum muaj kev tswj xyuas qhov sib piv ntawm ib nrab compression piv (piv txwv li, ib txoj kev tshawb fawb txo qis ib feem ntawm compression piv los ntawm 17.96% mus rau 15.91% kom nce throughput) thiab cov duab nrawm.
Kev kho cua sov:Kev kho cua sov yog qhov tseem ceeb rau kev kho cov khoom siv plasticity thiab kho nws cov khoom siv kho tshuab.
Intermediate Annealing: Yog tias kev ua haujlwm hnyav tshwm sim thaum lub sij hawm ntau lub voj voog, qhov nruab nrab annealing yuav tsum tau los kho cov yas.
Cov khoom tiav quenching thiab tempering:Kev sib xyaw ua ke thiab cov txheej txheem tempering feem ntau yog siv rau lub caij nplooj ntoos hlav tiav steel hlau. Piv txwv li, qee cov txheej txheem siv quenching kub ntawm 900-950℃thiab tempering kub ntawm 450-460℃kom ua tau siab elasticity thiab toughness.
Surface Treatment thiab Spring Coiling:Tom qab xaim kos duab, cov hlau nto yog oiled online los tiv thaiv xeb thiab muab lubrication rau kev ua haujlwm tom ntej, lossis ua rau electroplating thiab lwm yam kev kho mob. Thaum kawg, cov hlau yog coiled rau hauv ntau lub caij nplooj ntoos hlav siv CNC caij nplooj ntoos hlav tshuab (xws li 8- lossis 10-axis tshuab). Cov tshuab no tuaj yeem tsim cov springs nrog txoj kab uas hla ntawm 0.2 hli mus rau 2.5 hli, thiab loj dua.
