Kudzvanya Kunochinja Sei Panguva Yepakati-Frequency Spot Welding?

Mid-frequency spot welding, inozivikanwawo seyepakati-frequency resistance welding, inzira inoshandiswa zvakanyanya mumaindasitiri akasiyana ekubatanidza zvinhu zvesimbi. Munguva yewelding process, akati wandei ma paramita anoita basa rakakosha pakuona kunaka kweweld. Imwe yeaya maparamendi ndeyekumanikidzwa kuisirwa, iyo ine mhedzisiro yakakosha pakuita welding uye inoguma yakabatana simba. Muchinyorwa chino, isu tichaongorora kuti kudzvanywa kunochinja sei panguva yepakati-frequency nzvimbo welding nemhedzisiro yayo pamhando yeweld.

Kudzvanya chinhu chakakosha parameter panguva yekugadzira welding, sezvo ichipesvedzera kusangana pakati pezvishandiso uye maelectrodes, zvichikanganisa kugadzirwa kwekupisa uye kuyerera kwezvinhu. Pakati pe-frequency spot welding, kudzvanywa kunoitwa pakati pema electrode uye maworkpieces kunochinja chaiyo mukati mewelding cycle.

1. Kutanga Kuonana: Sezvo ma electrode anoswedera kune workpieces, kumanikidzwa kunotanga kuwedzera. Iyi yekutanga yekubata kumanikidza inovimbisa yakanaka magetsi conductivity uye yakakodzera kupisa chizvarwa pane welding interface.
2. Compression Phase: Kana ma electrode asangana neanoshanda, kumanikidza kunoramba kuchikwira sezvo ma electrode anomanikidza zvinhu pamwe chete. Iyi nhanho yekumanikidza yakakosha pakumisikidza yunifomu yekuonana nzvimbo uye kuderedza chero mapeji emhepo anogona kukanganisa weld mhando.
3. Welding Yazvino Chikumbiro: Sezvo iyo welding ikozvino inoshandiswa, kupikisa pane iyo interface kunogadzira kupisa, zvichitungamira kune yakasarudzika zvinhu kunyungudika. Munguva iyi, dzvinyiriro inogona kudonha zvishoma nekuda kwekupfava kwezvinhu uye kuumbwa kweiyo nugget yakanyungudutswa.
4. Bata Phase: Mushure meiyo welding ikozvino yakadzimwa, kudzvanywa kunochengetwa kwenguva pfupi panguva yekubata chikamu. Ichi chikamu chinobvumira zvinhu zvakanyungudutswa kuti zviome uye zvigadzire mubatanidzwa wakasimba we weld. Kumanikidzwa kunovimbisa kuti kusimba kunoitika nekurongeka kwakakodzera, kuderedza kukanganisa.
5. Kutonhora Phase: Sezvo weld joint inotonhora pasi, kumanikidzwa kunogona kusunungurwa zvishoma nezvishoma. Nekudaro, imwe nhanho yekumanikidza inogona kuramba ichishandiswa kudzivirira chero kutenderera kana kukanganisa kunokonzerwa nekukurumidza kutonhora.

Kusiyana kwekumanikidzwa panguva yepakati-frequency spot welding process inokanganisa zvakananga kunaka kweweld uye kutendeseka. Kutungamira kwakaringana kunobatsira kune zvinotevera zvinhu:

1. Nugget Formation: Kudzvinyirirwa kwakakodzera kunovimbisa kuti zvinhu zvakanyungudutswa zvakagoverwa zvakafanana, zvichigadzira yakasimba uye inopindirana weld nugget. Kudzvinyirira kusina kukwana kunogona kutungamirira kune kusaenzana kuumbwa kwe nugget uye majoini asina simba.
2. Minimized Porosity: Kudzvinyirira kwakakwana kunobatsira mukuderedza kuvapo kwehomwe dzemhepo uye voids mukati me weld. Kusakwana uku kunogona kuderedza mubatanidzwa uye kuderedza simba rayo rekutakura mutoro.
3. Yakaderedzwa Distortion: Kudzora kudzvanywa panguva yekutonhora kunodzivirira kukurumidza kukurumidza uye kunotevera kukanganisa kwe welded components.
4. Yakavandudzwa Magetsi uye Thermal Conductivity: Optimal pressure inosimudzira kusangana pakati pe electrode uye workpieces, zvichitungamira kune yakagadziridzwa magetsi uye ekupisa conductivity, zvichikonzera kugadzirwa kwakanaka kwekupisa.

Munzvimbo yepakati-frequency spot welding, kudzvanywa kwakasiyana kunoita basa rakakosha mukuona kunaka uye kuvimbika kwemajoini e weld. Kubva pakubata kwekutanga kusvika padanho rekutonhora, kutonga kudzvanywa kunovimbisa kuyerera kwakaringana kwezvinhu, kuumbwa kwe nugget, uye kutendeseka kwakabatana. Vagadziri uye vanogadzira welding vanofanirwa kunyatso tarisisa uye kudzora kudzvanywa paramita kuti vawane anowirirana uye emhando yepamusoro welds, zvichibatsira kune yakazara kurongeka kwemaitiro ezvakagadzirwa zvinhu.
