Makhalidwe ake ndi otani mpira wononga induction kutenthetsa ng’anjo kuzimitsa?

Kuzimitsidwa kwa ng’anjo yotenthetsera ya mpira nthawi zambiri kumakhala yopingasa, chifukwa screw ndi 5 ~ 6m kutalika, ngati mtundu woyimirira ugwiritsidwa ntchito, ngakhale thiransifoma ndi inductor zikugwiritsidwa ntchito kusuntha, ntchito yake imakhala yovuta kwambiri. Chithunzi 8-39 chikuwonetsa ntchito yayikulu yozimitsa ng’anjo yowotchera yopingasa ya mpira. Mng’anjo yowotchera ya mpira iyi imagwiritsa ntchito mphamvu yapakatikati ya thyristor pozimitsa, ndipo imakhala ndi milingo iwiri yamphamvu komanso pafupipafupi, yomwe ndi 160kW/10kHz ndi 50kW/30kHz. Yoyamba imagwiritsidwa ntchito ngati zomangira zokulirapo, ndipo zomalizazi zimagwiritsidwa ntchito ngati zomangira zocheperako. Kutalika kwakukulu kwa workpiece ndi 6m.

Ukadaulo wofunikira pakuumitsa kukulitsa kwa mpira ndikuwongolera kusinthika kwake. Deformation ili ndi mbali ziwiri: yoyamba ndikupindika, lomwe ndi vuto lomwe ma workpieces owonda ayenera kukumana nawo; yachiwiri ndi elongation deformation, yomwe ndi elongation ndi kufupikitsa phula lake kwa wononga mpira. Ngati kutalika kwa phula kuli kochuluka pambuyo pozimitsidwa, kutalika kwa wononga kumawonjezeka, kutalika kwake kumaposa mtengo wina, ndipo kukula kwa phula kumaposa kulolerana, screw idzachotsedwa.

Njira zina zapangidwa popanga chida ichi cha makina: ①Pogwiritsa ntchito chowongolera chapakati, chomwe chilipo kuwonjezera pa circumferential current, palinso gawo lotalikirapo, kotero kuti pamwamba ndi pansi pa ulusi zitha kutenthedwa; ②Zowononga zotsogola zimayendetsedwa ndi spacer Kusanthula ndikuzimitsa kumachitika kumtunda. Chifukwa chipika choyikirapo chikuyenda molimba ndi wononga chotsogolera, kusiyana kofanana kumasungidwa, ndipo zomangira zotsogola zimazunguliridwa ndikutenthedwa, zomwe zimatha kupanga yunifolomu yotentha; ③Chodzigudubuza chochepa chothandizira chowongolera chowongolera chimayikidwa kuti chichepetse kupindika.

Mbali ya makinawa ndikuwongolera kutalika. Kuwotcha kwa wononga mpira kumachitidwanso pamakina awa, pogwiritsa ntchito sitiroko yobwerera pakuwotcha. Pambuyo kutentha, izo zitakhazikika kachiwiri pa makina chida kumaliza ntchito kutentha kutentha. Kompyuta ya chida ichi imalumikizidwa ndi chosindikizira kuti isindikize zotsatira za muyeso wa gawo lililonse lozimitsidwa. Lipotili lingagwiritsidwe ntchito ngati khadi lolembera bwino. Mphamvu yozimitsa ng’anjo yowotchera ya mpira tsopano yapangidwa kukhala ma frequency atatu, ndipo pali zisankho zoyenera kwambiri zomangira ma diameter osiyanasiyana.
