Electrode Dhizaini uye Kutonhora muSeam Welding Machines

Mune seam welding michina, denderedzwa roller electrode anoshandiswa panzvimbo yeakajairwa nzvimbo welding matipi. Aya ma roller anowanzo siyana mudhayamita kubva pa50 mm kusvika 600 mm, ane masaizi anonyanya kushandiswa ari pakati pe180 mm ne250 mm. Ukobvu hwema roller kazhinji hunowira pakati pe10 mm ne20 mm.

Iyo yekusangana pamusoro peiyo roller electrode inogona kutora imwe yeanotevera maumbirwo:

Cylindrical surface

Spherical surface

Conical pamusoro (inoshandiswa muzviitiko zvakakosha senge majoini ane flanged)

Macylindrical rollers anowanzo gadzirwa ane mativi maviri-parutivi kana rimwe-sided chamfers, kunyanya kune zvikumbiro senge kumucheto-flanged majoini. Iyo yekubata pamusoro pehupamhi (ω) inosiyana nekukora kwechishandiso, kazhinji kubva pa3 mm kusvika pa10 mm. Spherical rollers ine curvature radius (R) pakati pe25 mm ne200 mm.

Cylindrical rollers anoshandiswa zvakanyanya kune welding simbi uye yakakwirira-tembiricha alloys.

Spherical rollers inopa zvirinani kupisa kupisa uye yakatsetseka indentation shanduko, ichiita kuti ive yakakodzera kune mwenje alloy welding, senge aluminium.

Kutonhodza Nzira dzeRoller Electrodes

Kudzivirira kupisa uye kuchengetedza electrode kuita, kutonhora kunokosha panguva seam welding. Mhando mbiri huru dzekutonhodza masisitimu anoshandiswa:

Kutonhodza Kwekunze:

Pakukwedhesa simbi dzisina ferrous uye simbi isina tsvina, mvura yemupombi yakachena inowanzokwana.

Pakuisa simbi yakajairika, 5% borax mhinduro inowanzoshandiswa kudzivirira ngura.

Internal Circulating Cooling:

Inoshandiswa kunyanya mumachina akagadzirirwa aluminium alloy welding, iyi nzira inotenderera mvura mukati me electrode.

Kunyange zvichinyanya kushanda, masisitimu ekutonhodza emukati anewo maitiro akaomarara uye anodhura.

Optimization Kubva pane Application

Kusarudza yakakodzera roller dhizaini uye kutonhora nzira kwakakosha kune inoshanda seam welding:

Zvemidziyo yeferrous uye alloys akakwira-tembiricha, macylindrical rollers ane kunze kutonhora anowanzo kukwana.

Kune simbi dzisina ferrous kana kupisa-sensitive simbi sealuminium kana magnesium alloys, spherical rollers akabatanidzwa nemukati memvura-inotonhorera masisitimu anokurudzirwa.

Iko kusanganisa kwakaringana kweroller geometry, hupamhi hwekusangana, uye kutonhora zano inogonesa inowirirana weld mhando, inorebesa hupenyu hwe electrode, uye inobatsira kudzivirira deformation yekupisa panguva yewelding.
