Chii chinonzi Pre-Kudzvanya Nguva muMedium Frequency Spot Welding Machines?

Medium frequency spot welding machines anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kwekushanda kwawo uye nemazvo mukujoinha simbi. Imwe yakakosha parameter mune iyo nzvimbo welding process inguva yekudzvanya, iyo inoita basa rakakosha mukuona kunaka uye kusimba kwemajoini akasungwa.

Pre-pressing time, inozivikanwawo sekuti kusvina nguva kana kubata nguva, inoreva nguva iyo ma electrode welding anoisa kudzvanywa kune ma workpieces neimwe simba isati yaiswa welding ikozvino. Ichi chikamu chakakosha nekuda kwezvikonzero zvakawanda:

1. Kuenzanisa uye Kubata:Munguva ye-pre-pressing nguva, ma electrode anoshandisa kumanikidza pane workpieces, kuve nechokwadi kurongeka kwakakodzera uye kuwirirana kunoenderana pakati pesimbi. Izvi zvinodzikisira mukana wekupokana kwemhepo kana kusaenzana kusangana, izvo zvinogona kutungamirira kune husina kunaka weld.
2. Surface Decontamination:Kuisa kumanikidza kunobatsira kusvina kunze zvinosvibisa, okisidhi, uye kusarongeka kwepasi kubva munzvimbo yekubatira. Izvi zvinoita kuti nzvimbo yakachena uye inoitisa kuti welding parizvino ipfuure, zvichikonzera weld yakasimba uye yakavimbika.
3. Kupfavisa zvinhu:Zvichienderana nesimbi dziri kuiswa welded, iyo pre-kudzvanya nguva inogona kubatsira mukupfava kwezvinhu pane welding point. Izvi zvinogona kufambisa kunotevera kuyerera kwezvinhu panguva yewelding process, zvichitungamira kune zvirinani fusion uye yakawedzera kusimba weld joint.
4. Stress Distribution:Kudzvanya kwakaringana kunobvumira kushushikana kugovanisa zvakaenzana kune ese maworkpieces. Izvi zvinonyanya kukosha kana uchibatanidza zvinhu zvine hutema hwakasiyana-siyana, sezvo zvichibatsira kudzivirira kukanganisa kana kuputika kwezvikamu.

Iyo yakakwana pre-kudzvanya nguva inogona kusiyana zvichienderana nezvinhu zvakaita serudzi rwezvinhu, ukobvu, simba re electrode, uye chaiyo welding application. Chiyero pakati pekubvumira nguva yakakwana yekuti izvo zvataurwa pamusoro apa zviitike pasina kurebesa kutenderera kwewelding.

Mukupedzisa, iyo pre-kudzvanya nguva yepakati-frequency spot welding machines ndiyo yakakosha parameter iyo inokanganisa zvakanyanya kunaka uye kutendeseka kwemajoini akaiswa. Nekuona kurongeka kwakaringana, decontamination, kupfava kwezvinhu, uye kugovera kushushikana, chikamu ichi chinoisa hwaro hwebudiriro yewelding process. Vagadziri nevashandisi vanofanirwa kunyatsoona uye kugadzirisa iyo pre-kudzvanya nguva kuti vawane mibairo yakakwana mukushandisa kwavo welding.
