Zvikonzero zveDeformation muNut Spot Welding uye Maitiro eKuzvigadzirisa?

Deformation chinhu chinowanzoitika mu nut spot welding, uko zvinhu zvakakandwa zvinogona kuita shanduko dzisingadiwe nekuda kwezvikonzero zvakasiyana. Ichi chinyorwa chinoongorora zvikonzero zviri shure kwewelding-induced deformation uye inopa mhinduro dzinoshanda kudzikamisa nyaya iyi.

1. Heat Concentration: Chimwe chezvikonzero zvinokonzeresa deformation mu nut spot welding ndiko kuwanda kwekupisa munzvimbo dzenzvimbo panguva yewelding. Uku kupisa kwakanyanya kunogona kutungamirira mukuwedzera kwekupisa, zvichikonzera kuputika kana kukotama kweworkpiece.
2. Inconsistent Welding Parameters: Zvisizvo kana zvisingaenderane welding paramita, senge yakawandisa welding ikozvino kana kurebesa welding nguva, inogona kubatsira mukupisa kusaenzana uye kunotevera deformation yezvikamu zvakasungwa. Zvakakodzera calibrated parameters zvakakosha kuti uwane yakaenzana kupisa kugovera.
3. Workpiece Material Properties: Zvishandiso zvakasiyana zvine akasiyana ekupisa ekufambisa uye ekuwedzera coefficients, ayo anogona kukanganisa kukanganisa kwavo kune deformation panguva yewelding. Musanganiswa wezvinhu zvisingaenzaniswi zvinogona kuwedzera dambudziko rekuchinja.
4. Kusakwana Kugadzirisa: Kusakwana kwekugadzirisa kana kusungirirwa kwakashata kwezvishandiso zvinogona kutungamirira kune yakanyanyisa kufamba panguva yewelding, zvichikonzera kukanganisa uye deformation.
5. Uneven Welding Pressure: Isiri-uniform yekumanikidza kugovera panguva yewelding inogona kukonzera kusaenzana kusungirirwa uye kunobatsira muku deformation, kunyanya muzvinhu zvitete kana zvakatetepa.
6. Residual Stress: Welding-induced residual stresses munharaunda yakabatana inogonawo kubatsira ku deformation. Aya madhiri emukati anogona kuzorora nekufamba kwenguva, zvichiita kuti workpiece ipindike kana kukanganisa.
7. Chiyero chekutonhodza: ​​Chiyero chekutonhora kana kusingadzoreki mushure mewelding inogona kukonzera kuvhunduka kwekupisa, zvichitungamira ku deformation munzvimbo yakasungwa.

Kugadzirisa Deformation: Kudzikamisa deformation mu nut spot welding, matanho akati wandei anogona kuitwa:

a. Optimize Welding Parameters: Nyatsoisa uye gadzirisa welding parameters, uchifunga nezvezvinhu zvivakwa uye majoini kumisikidzwa, kuti uwane yunifomu yekupisa kugovera.

b. Shandisa Yakakodzera Fixturing: Ita shuwa kuti maworkpiece akachengetedzwa zvakachengeteka uye akamisikidzwa zvakanaka panguva yewelding kudzikisa kufamba uye deformation.

c. Kudzora Welding Pressure: Chengetedza kuenderana uye kwakakodzera welding kumanikidza kuti uwane yunifomu uye yakagadzikana welds.

d. Preheat kana Post-Heat Kurapa: Funga preheating kana post-weld kupisa kurapwa kuti ubvise kushushikana kwasara uye kuderedza njodzi yekushanduka.

e. Kunodzorwa Kutonhodza: ​​Shandisa maitiro anodzorwa ekutonhodza kudzivirira kukurumidza kuchinja kwekupisa uye kuderedza deformation.

Deformation in nut spot welding inogona kuverengerwa kuzvinhu zvakaita sekudziya kwekushisa, kusawirirana kwemaparameta, zvinhu zvenyama, kugadzirisa, kudzvanywa kwewelding, kusara kunetseka, uye chiyero chekutonhora. Nekunzwisisa izvi zvinokonzeresa uye kutora matanho akakodzera, senge optimize welding paramita, kushandisa kwakaringana kugadzirisa, uye kushandisa inodzorwa kutonhora, vanoshanda vanogona kunyatso dzikamisa deformation nyaya, kugadzira emhando yepamusoro welds nekukanganisa kushoma uye kuwana mhedzisiro inodiwa mumashandisirwo akasiyana siyana.
