Iyo screw ingasangana sei nekupfeka kuramba uye yakakwirira-chaiyo yekugadzirisa zvinodiwa?

Mumunda wepurasitiki extrusion uye jekiseni molding, iyosiruuru imwendiyo yakakosha simba chikamu chese mutsara wekugadzira. Yakagadzirwa zvakanaka uye yakashongedzwa-yakagadzirwa, haingotaridzi chete kugadzikana kwezvinhu zvinotakura uye plasticizing mhando, asi zvakare inokanganisa zvakananga kurongeka kwezvakapera zvigadzirwa uye kuenderera kwekugadzirwa. Yakatarisana nezvinhu zvakaomarara zvine girazi fiber, calcium carbonate, mineral fillers, uye corrosive additives, kuchengetedza yakanakisa kupfeka kuramba uye yakagadzika kugadzirisa iko kurongeka kweichi chikamu chakakosha pasi pemutoro wenguva refu, kukweshera uye tembiricha yakanyanya kwave kutariswa kwehunyanzvi kune maneja emidziyo uye mainjiniya ekugadzira.

Kupfeka uye Corrosion: Zvikonzero Zvikuru Kubva paKugadzira Data

Zvinhu zvinotungamira kune premature screw surface kutadza zvine hukama zvakananga nehunhu hwezvinhu zvakagadziriswa. Zvinhu zvakasiyana zvinogadzira nzira dzakasiyana dzekukuvadza pane aSingle Screw,zvinoda zvigadziriso zvinonangwa. Tafura iri pazasi inopfupikisa marudzi matatu akajairika ekukuvadzwa kwezvinhu uye nemhedzisiro yawo:

Mukugadzira chaiko, kupfeka kweabrasive uye kukoromoka kwemakemikari zvinowanzochinjana, zvichiwedzera kukurumidza kuparara kwescuru. Naizvozvo, yakakwana yekudzivirira sisitimu inofanirwa kuvakwa kubva kune matatu maficha: zvinhu, kupisa kurapwa, uye pamusoro peinjiniya.

Yakakosha Tekinoroji Nzira dzeKunatsiridza Kupfeka Kupokana uye Kururamisa

Core Matanho: Kudzivirirwa kwakarongeka kubva paBase Material Kurapa kuenda kune Hardfacing Coating

Kuti uwane zvese zvakakwirira kupfeka kuramba uye kurongeka kwakanyanya, vagadziri vane hunyanzvi vanowanzo tora inotevera nhanho nhanho process system:

• Base zvinhu kudzima uye kupisa-Shandisa 38CrMoAlA alloy simbi, ita kudzima uye kudziya kwepamusoro-kupisa kuti uwane yunifomu inodziya sorbite chimiro, kubvisa kushushikana kwekugadzira uye kupa kunaka kwepakati kuoma.
• Precision kugaya-Shandisa yakakwirira-chaiyo cylindrical uye CNC thread grinders kuti uone chokwadi chejometri yemufananidzo wekubhururuka. Kutwasanuka, kushivirira kwenzwi, uye kushata kwepamusoro kweSingle Screwinodzorwa kune micron level, kuderedza kunyunguduka kumashure uye kupokana kwenzvimbo.
• Surface nitridingIsa gasi kana ion nitriding kuita 0.3–0.6 mm chena layer pane screw surface, uchiwana kuomarara kwepamusoro kweHV900–1100, kunatsiridza zvakanyanya kusakara kwekupfeka uku uchichengeta kuomarara kwepakati.
• Electroplating kana electroless plating-Pazvinhu zvinoparadza zvakanyanya (semuenzaniso, PVC, fluoroplastics), wedzera hard chromium kana electroless nickel layer pamusoro penitrided layer kuti ivhare ma micro-pores uye kuwedzera kusaita ngura, uku uchidzikisa kunyunguduka.
• Dual-alloy spray welding (PTA kana laser cladding)-Kune zvinhu zvinokurisa zvakanyanya segirazi fiber, calcium carbonate, kana zvinhu zvakadzokororwa, shandisa nickel-based kana cobalt-based alloy pamazano ekubhururuka, kuwana kuoma pamusoro peHRC60. Ichi chinoumbwa chimiro chinobvumira sikuruu kuchengetedza yakagadzikana plasticizing simba uye chaiyo clearance pasi pe-high-speed extrusion uye nharaunda dzinoparadza.

Precision Machining uye Maitiro Matching: Kuve nechokwadi chekuti Uniform Plasticizing uye Chigadzirwa Chinoenderana

Kunyatsoita kwepamusoro hakusi chete nezve screw's own dimensional tolerances, asiwo nezve kudzora kucheneswa pakati pescrew ndege yekunze dhayamita uye mbiya yemukati madziro. Chiitiko chinoratidza kuti kudzora kubvisirwa pakati aSingle Screw uye dhiramu mukati me 0.10-0.20 mm (zvichienderana nedhayamita) inoderedza zvakanyanya kunyunguduka kunyunguduka uye inowedzera kuburitsa chaiko. Pamusoro pezvo, optimized geometric parameters (compression ratio, L/D ratio) inofananidzwa negrooved barrel feed bushings inokwanisa kuwana yakakwira shear plasticizing pazasi sikuru yekumhanya, ichidzikisa tembiricha yekunyunguduka inosvika 10 ° C, nekudaro ichivandudza kunaka kwechigadzirwa uye kugadzikana kwedimensional.

Total Solutions for Harsh Operating Conditions

Zvemidziyo yakakosha senge huni-plastic composite (WPC), mapurasitiki einjiniya akazadzwa zvakanyanya, uye zvinhu zvakadzokororwa, vagadziri vanotungamira vakatama kubva pachikamu chakareruka chekugadzirisa kuenda kune akasanganiswa ehunyanzvi masevhisi anovhara "material kusarudzwa - process dhizaini - post-kurapa".

Semuyenzaniso, kune yakasimbiswa naironi ine inodarika 30% yegirazi faibha, sikururu inogona kugadzirwa ine inochinja-chinja gomo uye kudzika kwechaneru kudzika, neshanduko dzakatenderedzwa pamudzi wendege kuderedza kushushikana. Yakasanganiswa neaviri-alloy spray welding uye girazi polishing (pamusoro roughness Ra ≤ 0.05 μm), izvi zvinoderedza kabhoni dhipoziti njodzi uye kufambisa kuchenesa.

Mhedziso: Kukosha Kwenguva Yakareba Kwekudyara mune Yepamusoro-Kuita Screw

Muchidimbu, aSingle Screwinogadzirwa neyakanyatso dhizaini uye akawanda ekudzivirira ekudzivirira kwete chete zvakanyanya kuwedzera hupenyu hwayo hwesevhisi, asi zvakare inovandudza extrusion uye jekiseni kuumba simba rekushanda, inoderedza gadziriso frequency, uye inova nechokwadi chemhando yechigadzirwa kuenderana. Apo makambani ekugadzira epurasitiki anosarudza mugadziri akafananaZhoushan Nanhaiya Plastic Machinery Co., Ltd.- iyo ine cheni yakakwana yekugadzira, chaiyo machining midziyo, uye yakakura indasitiri ruzivo - vanowana imwe-yekumira simbisiro yehunyanzvi kubva kune screw material, kupisa kupisa kusvika pakuputira pamusoro, kuisa hwaro hwakasimba hwenguva refu yakagadzikana kugadzirwa.
