Iyo screw chikamu chakakosha cheiyo jekiseni molding muchina. Basa rayo ndere kutakura, compact, nyungudika, kumutsa uye kushandisa dzvinyiriro kune mapurasitiki. Maitiro aya anopedzwa nekutenderera kweiyo screw mugomba. Kana screw inotenderera, iyo mapurasitiki ichagadzira kupokana uye kuwirirana kumadziro emukati yebhari, pasi peiyo screw groove, iyo screw pamucheto kufambira mberi pamusoro, uye plastiki. Kufambira mberi kwemberi kwemapurasitiki mhedzisiro yekubatanidzwa uku kwekufamba, uye kupisa kunogadzirwa nekupokana kunoenderana nekuwedzera kupisa kwepurasitiki kunonyungudika purasitiki. Chimiro chechibharo chinokanganisa zvakananga kukura kwemhedzisiro iyi. Kuti uvandudze mhando yepurasitiki, screw inogona kugadzirwa semhando yekuparadzanisa, mhando yemhando yemhando yemhando kana kuti inopararira mhando screw.
Rudzi rwe screw barrel ye jection molding muchina:
1. Zvimiro zvekuchinja zvishoma nezvishoma zvishoma nezvishoma: Chikamu chekumusoro kwenguva refu, kushandurwa kwesimba kunonyanya kuenderera panguva yepurasitiki, uye zvinonyanya kushandiswa kwePVC uye mamwe mapurasitiki ane hurombo hwekugadzikana.
2. Zvinhu zveMutant Mutant Mutant Screw: Chikamu chekumanikidza ipfupi, uye kushandurwa kwesimba kwakanyanya panguva yepasi. Iyo inonyanya kushandiswa polyolefin, PA uye imwe crystalline mapurasitiki.
3. Zvimiro zveGreature-Chinangwa Chikuru-Chinangwa cheClrew: Iyo general-chinangwa screw inoshamisika inogona kugadziriswa mukugadziriswa kwemhando dzakasiyana-siyana uye kudzivirira kazhinji screw kutsiva.
Zvinhu zvebhari rekugadzira:
Parizvino, zvinhu zvinowanzoshandiswa muChina ndi45, 40cr na 38crmaria. Izvo zvinyorwa zvebhari rekunze kwekunze zvinowanzoshandiswa zvinowanzo shandiswa Alloy Simbi 34Craini naCRMOV9. Simba rechibereko yezvinyorwa izvi rinenge 900 mpa. Mushure mekutandwa, kuomarara kuri pamusoro pe 1000hv, iko kunodzivirira uye kunopesana nehurongwa hwakanaka. Tungsten carbide iyo barrel corrostion performance.
Kuchengetedza zuva nezuva kwebhari:
1. Usatange iyo muchina kana iyo mbiya yemabhara isati yasvika tembiricha yekudziya. Dzivirira zvidimbu zvesimbi nemarara kubva pakuwira mukati me hopper. Kana kugadzirisa zvinhu zvakagadzirwazve, iyo magineti hopper inofanira kuwedzerwa kudzivirira mafirita esimbi kuti apinde iyo huper.
2. Ita shuwa kuti mapurasitiki ari mugomba rakanyungudutswa kana richishandisa anti-ruponeso kuti adzivise kukuvara kwenhengo dzekutapurika kana iyo screw dzidzo. Paunenge uchishandisa mapurasitiki matsva, zvinhu zvasara zviri mubhari zvinofanirwa kucheneswa. Kana tembiricha yemapurasitiki yakanyungudutswa asi dema Kana chigadzirwa chiri jekiseni chakaumbwa, edza kuita kuti zvinhu zvive zvisina kunyatsojekeswa kuti uderedze torque yeTorrew yeScrew uye kuwedzera hupenyu hwebasa.
