Hluav taws xob tiv thaiv qhov chaw vuam yog ib txoj kev tsim khoom siv dav siv nyob rau hauv uas ob lossis ntau daim hlau tau koom ua ke los ntawm kev siv cov cua sov thiab siab. Hauv tsab xov xwm no, peb yuav tshawb txog theem tseem ceeb ntawm cov txheej txheem no - lub zog cua sov theem.
Nkag siab txog Hluav Taws Xob Resistance Spot Welding
Hluav taws xob tiv thaiv qhov chaw vuam, feem ntau hu ua qhov chaw vuam, suav nrog kev siv hluav taws xob tam sim no los ua kom muaj cua sov ntawm qhov chaw ntawm kev sib cuag ntawm ob qhov chaw hlau. Cov txheej txheem no feem ntau yog ua haujlwm hauv tsheb, aerospace, thiab kev tsim kho kev lag luam los tsim kom muaj zog thiab txhim khu kev qha welds.
The Power Heating Phase
Lub zog cua sov theem yog ib kauj ruam tseem ceeb hauv qhov chaw vuam txheej txheem. Thaum lub sij hawm no, ib tug siab tam sim no yog dhau los ntawm cov electrodes, uas yog nyob rau hauv ncaj qha kev sib cuag nrog cov hlau los xij yuav tsum tau koom. Cov hluav taws xob tsis kam ntawm qhov chaw sib txuas ua rau muaj cua sov, ua rau cov hlau yaj thiab fuse ua ke.
Kev txiav txim siab tseem ceeb thaum lub sij hawm Lub Hwj Chim Cua sov
- Tam sim no thiab Voltage Control: Kev tswj xyuas meej ntawm qhov tam sim no thiab qhov hluav taws xob yog qhov tseem ceeb thaum lub sij hawm fais fab cua sov theem. Qhov no ua kom ntseeg tau tias cov cua sov tsim nyog, tiv thaiv overheating lossis cua sov tsis txaus.
- Electrode Tsim: Kev tsim ntawm cov electrodes yog qhov tseem ceeb heev rau kev ua tiav qhov kev vam meej. Cov khoom siv hluav taws xob zoo thiab cov duab raug xaiv los ua kom yooj yim rau kev hloov hluav taws xob thiab txo qis electrode hnav.
- Lub sijhawm vuam: Lub sij hawm ntawm lub hwj chim cua sov theem, hu ua lub sij hawm weld, yog ua tib zoo tswj. Nws feem ntau yog ib feem ntawm ib lub thib ob tab sis tuaj yeem sib txawv nyob ntawm cov khoom siv thiab thickness tau welded.
- Txias: Tom qab lub zog cua sov theem, lub cua txias ua raws li cov khoom sib txuas. Kev ua kom txias tuaj yeem suav nrog kev siv dej lossis lwm yam khoom siv cua txias kom tsis txhob muaj cua sov ntau dhau.
Qhov zoo ntawm Electric Resistance Spot Welding
- Ceev: Spot welding yog txheej txheem ceev, ua kom haum rau cov khoom ntim siab.
- Kev sib raug zoo: Thaum teeb tsa kom raug, qhov chaw vuam muab cov vuam zoo ib yam thiab txhim khu kev qha.
- Lub zog: Lub resulting welds muaj zog, feem ntau nrog cov khoom zoo ib yam li lub hauv paus hlau.
- Kev huv huv: Spot welding tsim cov pa luam yeeb tsawg, pa taws, lossis cov khoom siv los ntawm cov khoom, ua rau nws tus phooj ywg ib puag ncig.
Kev sib tw thiab kev txiav txim siab
Thaum hluav taws xob kuj qhov chaw vuam muaj ntau qhov zoo, nws tsis yog tsis muaj nws cov nyom. Kev saib xyuas cov cuab yeej siv tau zoo, kev saib xyuas electrode, thiab kev cob qhia tus neeg teb xov tooj yog qhov tseem ceeb rau kev ua tiav cov vuam zoo tsis tu ncua. Tsis tas li ntawd, qhov chaw vuam tej zaum yuav tsis haum rau tag nrho cov ntaub ntawv los yog thicknesses.
Nyob rau hauv lub ntiaj teb no ntawm kev tsim, hluav taws xob kuj qhov chaw vuam thaum lub sij hawm lub hwj chim cua sov theem yog ib tug txheej txheem tseem ceeb rau kev koom tes hlau zoo thiab zoo. Nkag siab txog qhov tsis sib xws ntawm theem no, suav nrog kev tswj tam sim no thiab voltage, tsim electrode, vuam lub sij hawm, thiab txias, yog qhov tseem ceeb rau kev tsim cov welds muaj zog thiab txhim khu kev qha. Thaum ua tiav kom raug, hluav taws xob tiv thaiv qhov chaw vuam ua rau tsim cov khoom ruaj khov thiab nyab xeeb thoob plaws ntau yam kev lag luam.
