Hollow kuwulutsa ndi kuumba kwa extrusion kapena jekeseni wopangidwa ndi theka-kusungunuka pulasitiki billet kwa mitundu yosiyanasiyana yowoneka abrasive, kutsekedwa abrasive, mu billet molingana ndi psinjika mpweya kuwomba, kotero kuti kukumana khoma la abrasive, pambuyo kuzirala. nkhungu ndi zamanja dzenje.Itha kugwiritsidwa ntchito popanga mafuta odyeka, zakumwa, zakumwa, zokometsera, mkaka ndi zinthu zina zopangira chakudya ndi mabotolo apulasitiki, mitundu yosiyanasiyana ya annular, mabwalo, owoneka bwino komanso migolo yachitseko, zitini ndi zaluso zina zopanda kanthu.
Hollow nkhonya akamaumba ndi mapindikidwe pulasitiki pulasitiki pulasitiki akusowekapo anaika mu akupera chida, psinjika mpweya mu akusowekapo, kuwomba izo, kupanga izo pafupi ndi nkhungu patsekeke khoma, pambuyo kuzirala kupeza mawonekedwe a dzenje pulasitiki mbali kupanga ndi processing. .Malinga akamaumba njira si chimodzimodzi, akhoza kugawidwa m'njira zinayi.
1, extrusion kuwomba akamaumba
1 - Mutu wa makina owonjezera 2 - kuwomba kuumba kufa 3 - tubular billet 4 - mpweya wopopera kutentha chubu 5 - pulasitiki
Woyamba extruder extruded tubular billet;Tingafinye chigawo cha kumaliza anagubuduza chitoliro ndi kuchiyika mu akupera chida pamene kutentha, kutseka kumanzere ndi kumanja kwa ena clamping mtundu akusowekapo a poyera akupera chida;
Ndiye kwa concave kufa mu mpweya psinjika, kuti billet kuwomba ndi Ufumuyo mkati khoma la kufa pachimake tebulo;
Potsirizira pake, pambuyo posungira kupanikizika, firiji ndi kupanga, imatha kuchotsa kuponderezedwa kwa mpweya ndi nkhungu kuchotsa mbali zapulasitiki.
Extrusion kuwomba akamaumba nkhungu kapangidwe ndi losavuta, ntchito ndalama zochepa, ntchito yeniyeni ndi yosavuta, oyenera zosiyanasiyana pulasitiki dzenje kuwomba kuwomba.Extrusion kuwomba akamaumba zolakwika si kophweka symmetrical khoma makulidwe, mbali pulasitiki ayenera kukonzedwa pambuyo kuchotsa burr.
2, jekeseni kuwomba akamaumba
1 - Mphuno ya jekeseni 2 - Mtundu wa singano wopanda kanthu 3 - maziko a nkhungu opanda dzenje (pachimake) 4 - Chotenthetsera chamagetsi 5 - kuumba nkhungu 6 - zigawo zapulasitiki
jekeseni woyamba nkhungu mu makina jakisoni kuti dzenje sipekitiramu mtundu akusowekapo;
Ndiye pachimake ndi billet amasunthidwa mu nkhungu yowomba, pachimake ndi cheho ndipo khoma lamkati lili ndi mbale ya microporous;
Kenako, nkhungu zokhoma ndi wothinikizidwa chitoliro cha pachimake kutsinde mu mpweya, kuti akusowekapo kuwomberedwa ndi Ufumuyo mkati khoma la concave nkhungu pamwamba pa abrasive chida;
Potsirizira pake, pambuyo posungira kupanikizika, firiji ndi kupanga, imatha kuchotsa kuponderezedwa kwa mpweya ndi nkhungu kuchotsa mbali zapulasitiki.
Ubwino wa jekeseni nkhonya akamaumba kuti khoma makulidwe a mbali pulasitiki bwino-proportional popanda zouluka m'mphepete, popanda kupanga ndi processing.Chifukwa cha singano mtundu sipekitiramu akusowekapo, kotero palibe olowa pansi mbali pulasitiki, mkulu compressive mphamvu, kupanga mkulu ndi kupanga dzuwa, koma ntchito ndalama makina ndi zipangizo ndi abrasive zida ndi lalikulu kwambiri, makamaka kwa mtanda. kupanga zing'onozing'ono ndi zazing'ono zapulasitiki.
3, jekeseni kutambasula kuwomba kuumba
1 - Injector nozzle 2 - jekeseni nkhungu 3 - kutambasula mandrel (chubu chowotcha) 4 - kuumba nkhungu 5 - pulasitiki
Jekeseni wotambasulira nkhonya kuumba ndi kupanga ndi processing njira kuti jekeseni akamaumba sipekitiramu akusowekapo ndi kutenthedwa ndi kutentha koyenera pansi pa mfundo yankho ndiyeno kuikidwa mu abrasive chida.Ndodo yowonjezera imayamba kuchitidwa motambasulira ma radial kenako ndikumangirira mlengalenga.
Pambuyo potambasulira mbali za pulasitiki zomveka bwino, mphamvu yolimbikitsira yamphamvu, mphamvu yapamtunda, kuuma kopindika ndi mawonekedwe okana nthunzi nthawi zambiri amakhala bwino.Jekeseni wotambasulira jekeseni chinthu chodziwika bwino kwambiri ndi mabotolo amadzi amchere a polyester.Jekeseni yowongoka kuwombera imatha kugawidwa munjira yotentha ya billet ndi njira yozizira ya billet njira ziwiri zoumba.
Yoyamba jekeseni akamaumba dzenje sipekitiramu akusowekapo;Sunthani billet kumalo otambasula ndi kuwomba kuti mutambasule ndikuwomba;Pambuyo kuthamanga posungira, refrigeration kunja nkhungu anachotsa mbali pulasitiki.
Njira yamtunduwu imapulumutsa kutenthedwa kwa billet yozizira ndikupulumutsa mphamvu.Komanso, dongosolo billet ndi Tambasula kuwombeza akamaumba ikuchitika pa makina omwewo ndi zipangizo, amene ali m'dera laling'ono, ndi yabwino kwa mosalekeza chitukuko cha kupanga ndi kupanga, ndipo ali mkulu mlingo wa luso zokha.
Cold billet jakisoni wotambasulira jekeseni ndi jekeseni wa kutentha kwabwino kwa billet pa kutentha koyenera ndikuyiyika mu nkhungu yowomba kuti ipangitse kuumba.Posankha kuzizira billet kupanga njira, jekeseni wa billet ndi kutambasula kuwomba akamaumba mbali pulasitiki ikuchitika pa makina osiyana ndi zipangizo motero.Asanayambe kuwombera kuwombera, kuti athe kubwezera kutentha komwe kumatulutsidwa ndi firiji ya billet, kutentha kwachiwiri kuyenera kuchitidwa kuti kuwonetsetse kuti billet ikuwomba.
4 mapepala apulasitiki opukutira
Pulasitiki pepala kuwomba akamaumba jekeseni akamaumba kapena extrusion akamaumba pulasitiki pepala Kutentha, zikhale zofewa, mu nkhungu concave, zokhoma pakati pa mbale pulasitiki mu mpweya psinjika ndi kupanga dzenje pulasitiki mbali.
