Nekuvandudza tekinoroji uye hupfumi, ptfe yakashandiswa mune dzakawanda uye yakawanda minda, uye yave chinhu chakakosha kugadzirisa akawanda akakosha matekinoroji mukutsvagisa kwesainzi, mauto nenharaunda dzevagari uye kuvandudza tekinoroji yekugadzira.Kuti tirambe tichivandudza kugadzirwa kwepolymer ptfe, takatanga kutora maitiro ekugadzirwa kwepamusoro, ayo anokodzera yakakwirira viscoelastic material -- Ram-punch extrusion.

Zvinoenderana nemusimboti we "forging", plunger stamping extruder inonyanya kutora plunger ine diki diki chikamu nzvimbo uye yakakwirira frequency stamping kusundira zvinhu mudhiramu re extruder.Kuenzaniswa neyechinyakare hydraulic column extruder, ine hunhu hwepamusoro stamping frequency, yakanaka melt plasticizing effect, yakanaka chigadzirwa mhando, zviri nyore zvishandiso uye maitiro.
Maererano nekugadzira maitiro eRam-punch extruder, iyo extrusion process inoongororwa uye kudzidza.Iyo yemuviri modhi yeiyo yese extrusion process ye plunger ram extruder inotangwa, iyo yakakamurwa kuita zvikamu zvishanu: yakasimba yekudyisa chikamu, kunyungudika chikamu, shunt chikamu, kuumba chikamu uye kutonhora chikamu.Mhedzisiro yekufa kureba uye kudzvinyirira vibration frequency pane extrusion process yakaongororwa.Ongororo mhedzisiro inoratidza kuti: kunyangwe paine kushanduka kukuru kwekumanikidza pamusuwo wekunyunguduka, asi pakumanikidza kwese kubva pakupinda kuenda kune kunze kwakaderedzwa zvishoma nezvishoma, nekudaro kuve nechokwadi chekumanikidza kwakaringana kusundira zvinhu extrusion, uye nekuswedera kwainosvika kune kupedza mold outlet pressure uye kukurumidza kushanduka idiki, saka inogona kuve nechokwadi kuenderera kweextrusion, pakupedzisira uwane zvigadzirwa zvemhando yepamusoro.Hurefu uye stamping frequency yefa ine zvimwe zvinofurira pane extrusion pressure nekumhanya.Nekuda kweiyo viscosity yakakwira yePTFE, kufa kwenguva refu kunofanirwa kusarudzwa, uye iyo stamping frequency pakati pe5-6hz yakakodzera.
Ram plunger extrusion machining polymer PTFE inzira nyowani yekugadzira, asi mukuita kwekugadzira zvinhu, zvakare haigone kusiya kuyerera kwezvinhu uye deformation, rheological maitiro uye mutemo, kunzwisisa maitiro ekuumbwa kwemaitiro kusarudzwa, kushanda uye optimization control. uye kunatsiridza molding midziyo ine yakakosha inoshanda kukosha.Plunger stamping haisi iyo yakatsiga-mamiriro machining nzira, uye kune vibration mukuita chitambi.Izvo zvakakosha zvikuru kudzidza maitiro ekuita kwepolymer pasi pechiito chevibration field, uye kukurukura kuti yakawanda sei iyo vibration ichaita pakuyerera kugadzikana, kuitira kuti udzidze simba rekuumbwa kwezvinhu zvepolymer uye kukwidziridza kugadzirwa.
