Ndeipi nhanho yekugadzira yepakati frequency spot welding muchina?

The forging stage of a medium frequencynzvimbo welding muchinainoreva nzira iyo electrode inoramba ichimanikidza pane weld point mushure mekunge welding current yagurwa. Munguva iyi, weld point inosungirirwa kuti ive nechokwadi chekusimba kwayo. Kana simba racho ragurwa, musimboti wakanyungudutswa unotanga kutonhora nekupenya mukati meganda resimbi rakavharirwa, asi rinogona kusadzikira zvakasununguka.

Pasina kumanikidzwa, iyo weld point inokonzeresa shrinkage makomba uye kuputika, izvo zvinogona kukanganisa simba rayo. Electrode pressure inofanirwa kuchengetedzwa mushure mesimba-kudzima kudzamara simbi yakanyungudutswa yanyatsosimba, uye nguva yekugadzira inoenderana nekukora kwechishandiso.

Kune akakora maworkpiece ane makobvu esimbi akatenderedza musimboti wakanyungudutswa, kuwedzera kwefogi kumanikidzwa kungave kuri madikanwa, asi nguva uye nguva yekuwedzera kumanikidzwa kunofanirwa kudzorwa nehungwaru. Kukasira kuisa dzvinyiriro kunogona kukonzera simbi yakanyunguduka kuti ibude, ukuwo kunonoka kupinza kunogona kuita kuti simbi iome pasina kufogisa. Kazhinji, kuwedzera kwekumanikidza kwekugadzira kunoshandiswa mukati me 0-0.2 masekondi mushure memagetsi-kudzima.

Izvo zviri pamusoro zvinotsanangura maitiro akajairwa ekugadzira weld point. Mukugadzirwa chaiko, matanho akasarudzika anowanzo kutorwa zvichibva pane zvakasiyana zvinhu, zvimiro, uye welding mhando zvinodiwa.

Kune zvinhu zvinogara zvichipisa kuputika, yekuwedzera inononoka kutonhora pulse welding matekiniki anogona kushandiswa kudzikisa chiyero chekusimba chesimbi yakanyungudutswa. Kune zvinhu zvinodzimwa uye zvakadzikama, post-weld kupisa kurapwa pakati pema electrode maviri anogona kuitwa kuvandudza brittle quenching chimiro chinokonzerwa nekukurumidza kupisa uye kutonhora.

Panyaya yekumanikidza kushandiswa, saddle-shaped, stepped, kana multi-step electrode pressure cycles inogona kushandiswa kusangana nezvinodiwa welding yezvikamu zvine mhando dzakasiyana siyana.

Kana iwe uchifarira yedu otomatiki michina uye mitsara yekugadzira, ndapota taura nesu: leo@agerawelder.com
