Ungasilungisa Kanjani Isikhathi Se-Pre-Welding Somshini Welding We-Resistance Spot?

I-Resistance spot welding iyinqubo yokuhlanganisa esetshenziswa kakhulu ekukhiqizeni, futhi isikhathi sangaphambi kokushisela siyipharamitha ebalulekile engaba nomthelela omkhulu kwikhwalithi ye-weld. Kulesi sihloko, sizoxoxa ngendlela yokulungisa isikhathi sangaphambi kokushisela umshini wokushisela indawo yokumelana ukuze uzuze imiphumela emihle.

Ukuqonda Isikhathi Sangaphambi Kokushisela:

Ngaphambi kokungena enqubweni yokulungisa, kubalulekile ukuqonda ukuthi yisiphi isikhathi sangaphambi kokushisela nokuthi kungani kubalulekile. Isikhathi sangaphambi kokushisela, esaziwa nangokuthi isikhathi sokuminyanisa noma isikhathi sokubamba, isikhathi lapho ama-electrode okushisela athintana nezinto zokusebenza ngaphambi kokuba kusetshenziswe umsinga wangempela wokushisela. Lesi sikhathi sivumela ama-electrode ukuthi acindezele ama-workpieces, enze isixhumi esibonakalayo esiqinile futhi asuse noma yikuphi ukungcola okungaphezulu, okuqinisekisa ukushisela okuqinile nokuthembekile.

Izinto Ezithonya Isikhathi Sangaphambi Kokushisela:

Izinto ezimbalwa zingathonya isikhathi esifanele sangaphambi kokushisela sohlelo olunikeziwe lwe-welding:

1. Uhlobo Lwezinto:Izinto ezihlukene zinezimo ezishisayo ezishisayo kanye nokumelana nogesi. Ngenxa yalokho, zingadinga izikhathi ezihlukene zangaphambi kokushisela ukuze kuzuzwe ikhwalithi yokushisela oyifunayo.
2. Ubukhulu Bezinto:Izinto eziwugqinsi ngokuvamile zidinga izikhathi ezinde zangaphambi kokushisela ukuze kuqinisekiswe ukushisisa okufanele nokugeleza kwempahla.
3. I-Electrode Force:Amandla asetshenziswa ama-electrode okushisela adlala indima ebalulekile ekunqumeni isikhathi esidingekayo sangaphambi kokushisela. Amandla aphezulu angase adinge izikhathi ezinde zangaphambi kokushisela.
4. I-Electrode Geometry:Ukuma nosayizi wama-electrode welding kungathinta ukusatshalaliswa kwengcindezi kanye namanje, okungase kube nomthelela esikhathini esidingekayo sangaphambi kokushisela.

Ukulungisa Isikhathi sangaphambi kokushisela:

Ukuze ulungise isikhathi sangaphambi kokushisela umshini wokushisela indawo yokumelana, landela lezi zinyathelo:

1. Qonda Izinto Zakho:Nquma uhlobo nokujiya kwezinto ozishiselayo. Bheka imihlahlandlela yokushisela noma uthintane nochwepheshe bezinto ezibonakalayo uma kudingeka.
2. Cabanga nge-Electrode Force:Qinisekisa ukuthi amandla e-electrode asethwe ngendlela efanele. Uma amandla ephansi kakhulu, ungase udinge ukwandisa isikhathi sangaphambi kokushisela ukuze unxephezele ukucindezela okunganele.
3. Ukuhlola:Ngokuvamile kudingekile ukwenza uchungechunge lwamashisela okuhlola anezikhathi ezihlukile zokushisela ukuze uthole ubude besikhathi obufanele bohlelo lwakho lokusebenza oluthile.
4. Hlola Ikhwalithi Ye-Weld:Ngemva kokushisela ukuhlolwa ngakunye, hlola ngokucophelela ikhwalithi yokushisela. Bheka izimpawu zokungahlangani okunganele, i-spatter eyeqile, noma okunye ukukhubazeka. Isikhathi esifanelekile sangaphambi kokushisela kufanele sibangele ukushisela okungaguquki, okusezingeni eliphezulu.
5. Rekhoda Okutholakele:Gcina irekhodi lezikhathi zokushisela ezisetshenziselwa ukuhlolwa ngakunye, kanye nekhwalithi yokushisela ehambisanayo. Le datha izokusiza ukuthi ubone isikhathi esingcono kakhulu sokushisela ama-welds azayo.
6. Ukuhleleka Kwayo:Qhubeka ulungisa futhi ulungise kahle isikhathi sangaphambi kokushisela kuze kube yilapho uzuza ngokuqhubekayo ikhwalithi yokushisela oyifunayo.

Ukulungisa isikhathi sangaphambi kokushisela umshini wokushisela indawo yokumelana kuyisinyathelo esibalulekile ekuzuzeni ukushisela kwekhwalithi ephezulu. Ngokucabangela izakhiwo zezinto ezibonakalayo, amandla e-electrode, kanye nokwenza ukuhlola okuhlelekile, ungathola isikhathi esilungile sangaphambi kokushisela sohlelo lwakho lokusebenza oluthile lokushisela. Lokhu kunaka imininingwane kuzoholela ekushiseleni okuqinile, okuthembeke kakhulu kanye nokwenza ngcono ukusebenza kahle kokukhiqiza.
