Pressure Welding Tus Thawj Coj Ua Haujlwm hauv Kev Tsim Khoom Loj

Siab vuam siv "siab" raws li cov tub ntxhais koom nrog txoj kev, yuav tsum tsis muaj (los yog me ntsis) cov khoom muab tub lim. Nws muaj kev sib txuas ceev ceev thiab tus nqi qis, ua rau nws tshwj xeeb tshaj yog haum rau kev sib koom ua ke ntawm nyias daim hlau thiab cov xov hlau. Nws yog dav siv hauv kev lag luam xws li kev tsim tsheb, kev tsim khoom siv hauv tsev, thiab ntim khoom siv hluav taws xob.

(I) Resistance Vuam: Qhov "Core Technology" hauv Automotive Manufacturing

Resistance vuam siv lub hauv paus ntsiab lus ntawm "kev tiv thaiv cua sov." Nws clamps lub workpieces thiab dhau ib tug loj tam sim no los ntawm lawv, ua rau siab kub hauv zos kom yaj (los yog plastically deform) cov hlau. Tom qab txias, weld me ntsis yog tsim. Nws tau muab faib ua peb hom: qhov chaw vuam, seam vuam, thiab qhov projection vuam, ntawm qhov chaw vuam yog "lub ntsiab lus tseem ceeb" hauv tsheb lub cev vuam.

1. Spot Welding: Lub Tshuab "Dot Matrix" rau kev sib koom ua ke zoo

Lub hauv paus ntsiab lus: Ob lub electrodes clamp lub nyias daim hlau thiab dhau qhov tam sim no loj ntawm 1000-10,000A los ntawm lawv. Kev tiv thaiv kev sib cuag ntawm cov electrodes thiab cov phaj nyias ua kom sov, ua rau cov hlau hauv zos melting los ua "fusion core." Tom qab fais fab tuag, lub siab yog tswj kom txog thaum txias los ua ib qho chaw weld. Teem ntau qhov chaw weld ua rau thaj chaw loj tuaj koom.

Cov ntsiab lus ua haujlwm:

•     Electrode Xaiv:Siv tooj liab-chromium alloy electrodes rau vuam low-carbon steel thiab tooj liab-zirconium alloy electrodes rau vuam galvanized steel los xij. Khaws lub hau electrode kom tiaj tus thiab rov ua dua lub sijhawm tom qab hnav (qhov taub taub feem ntau yog 2-3 zaug ntawm lub phaj tuab).

•     Parameter Control:nruj me ntsis phim lub sij hawm vuam (0.1-0.5 vib nas this), tam sim no (hloov raws li lub phaj thickness; piv txwv li, 3000-4000A rau 2 hli tuab steel daim hlau), thiab siab (xyuas kom nruj sib cuag ntawm cov electrodes thiab cov workpieces kom tsis txhob muaj kev tiv thaiv ntau dhau) los tiv thaiv txias soldering los yog kub hnyiab.

•     Kev soj ntsuam zoo:Weld me ntsis yuav tsum tsis muaj kab nrib pleb thiab spatter. Thaum lub sij hawm ntsuas tensile nrog lub tshuab ntsuas tensile, "lub hauv paus hlau tearing" es tsis yog "weld spot detachment" yuav tsum tshwm sim los xyuas kom meej vuam lub zog.

2. Seam Vuam: Qhov "Nruam Kev Tiv Thaiv Kab" rau cov qauv kaw

Seam welding zoo ib yam li hauv paus ntsiab lus rau qhov chaw vuam, tab sis cov electrodes yog hloov nrog tooj liab rollers. Cov rollers tig thiab hla lub zog tam sim no los ua ib qho txuas txuas ntxiv. Nws yog tsim rau welding sealed lug xws li automotive roj tso tsheb hlau luam, dej rhaub liner, thiab pipeline pob qij txha. Thaum lub sijhawm ua haujlwm, tswj lub siab ntawm cov menyuam thiab kev sib hloov ceev kom ntseeg tau tias muaj kev sib txuas tsis tu ncua, tsis muaj qhov sib txuas. Thaum vuam galvanized steel los xij, tsis tu ncua ntxuav cov zinc txheej ntawm cov menyuam nto kom tsis txhob muaj kev sib cuag tsis zoo.

(II) Kev sib txhuam vuam: Qhov "Kev xaiv muaj zog siab" rau cov ncej zoo li qhov

Kev sib txhuam vuam ua tiav kev sib koom ua ke los ntawm "high-speed rotational kev sib txhuam cua sov." Nws clamps ob lub cylindrical qhov chaw (xws li shafts thiab rods), nrog rau ib qho kev tig ntawm kev kub ceev (1000-5000r / min). Cov cua sov uas tsim los ntawm kev sib txhuam coj qhov chaw sib cuag mus rau lub xeev yas. Tom qab nres kev sib hloov, lub siab ntau dua yog siv los ua ib qho kev sib txuas uas muaj zog.

•    Core Advantages:Lub zog vuam siab (weld lub zog siab dua li ntawm lub hauv paus hlau), tsis muaj porosity lossis slag suav nrog, thiab vuam ceev ceev (ib lub sijhawm vuam

•    Cov ntsiab lus ua haujlwm:Tswj qhov kev sib hloov ceev thiab kev sib txhuam siab kom ntseeg tau tias qhov kub thiab txias ntawm qhov chaw sib cuag (tsis txhob muaj cua sov hauv zos); Thaum vuam cov ntaub ntawv sib txawv (xws li hlau thiab tooj liab), kho qhov kev sib hloov ceev thiab siab kom tsis txhob tawg los ntawm qhov sib txawv ntawm thermal expansion coefficients.
