Lub sij hawm Pre-Pressing nyob rau hauv nruab nrab zaus Spot Vuam Tshuab yog dab tsi?

Nruab nrab zaus qhov chaw vuam tshuab yog dav siv nyob rau hauv ntau yam lag luam rau lawv cov efficiency thiab precision nyob rau hauv kev koom tes hlau. Ib qho tseem ceeb ntawm qhov chaw vuam txheej txheem yog lub sij hawm ua ntej nias, uas ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo thiab kav ntev ntawm cov pob qij txha welded.

Lub sij hawm ua ntej nias, tseem hu ua lub sij hawm nyem los yog tuav lub sij hawm, hais txog lub sij hawm thaum lub sij hawm vuam electrodes siv siab rau lub workpieces nrog ib tug tej yam quab yuam ua ntej qhov tseeb vuam tam sim no yog siv. Lub sijhawm no yog qhov tseem ceeb rau ntau qhov laj thawj:

1. Kev sib txuas thiab kev sib cuag:Thaum lub sij hawm ua ntej nias, cov electrodes exert siab rau lub workpieces, kom ntseeg tau tias kev sib raug zoo thiab kev sib cuag ntawm cov hlau nto. Qhov no txo ​​qis qhov muaj peev xwm ntawm huab cua sib txawv lossis kev sib cuag tsis sib xws, uas tuaj yeem ua rau tsis zoo weld zoo.
2. Decontamination ntawm qhov chaw:Kev siv lub siab pab txhawm rau tshem tawm cov kab mob, oxides, thiab qhov tsis sib xws ntawm qhov chaw vuam. Qhov no ua kom muaj qhov huv thiab ua tau zoo rau cov vuam tam sim no kom dhau mus, ua rau muaj zog dua thiab txhim khu kev qha.
3. Khoom siv Softening:Nyob ntawm cov hlau raug welded, lub sij hawm ua ntej nias tuaj yeem ua rau cov khoom muag muag ntawm qhov chaw vuam. Qhov no tuaj yeem pab txhawb cov khoom ntws tom ntej thaum lub sijhawm vuam, ua rau kom zoo dua fusion thiab muaj zog vuam sib koom ua ke.
4. Stress Distribution:Kev nias ua ntej ua ntej tso cai rau kev ntxhov siab kom faib cov khoom sib npaug ntawm cov khoom ua haujlwm. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum koom nrog cov khoom sib txawv ntawm cov thicknesses, vim nws pab tiv thaiv kev cuam tshuam los yog kev sib hloov ntawm cov khoom.

Lub sij hawm zoo tshaj plaws ua ntej nias tuaj yeem sib txawv raws li cov khoom siv, thickness, electrode quab yuam, thiab daim ntawv thov vuam tshwj xeeb. Nws yog qhov sib npaug ntawm qhov tso cai rau lub sijhawm txaus rau cov txiaj ntsig tau hais los saum toj no los ua qhov chaw yam tsis tas yuav ncua lub voj voog vuam.

Hauv kev xaus, lub sij hawm ua ntej nias nyob rau hauv nruab nrab zaus qhov chaw vuam tshuab yog ib qho tseem ceeb parameter uas cuam tshuam qhov zoo thiab kev ncaj ncees ntawm cov pob qij txha welded. Los ntawm kev ua kom muaj kev sib raug zoo, decontamination, cov khoom muag muag, thiab kev xa tawm kev ntxhov siab, theem no tau teeb tsa lub hauv paus rau txoj kev vuam zoo. Cov neeg tsim khoom thiab cov neeg ua haujlwm yuav tsum ua tib zoo txiav txim siab thiab kho lub sijhawm nias ua ntej kom ua tiav cov txiaj ntsig zoo hauv lawv cov ntawv thov vuam.
