Nhoroondo ye rebar coupler

Muindasitiri yekuvaka, nzira dzechinyakare dzekusimbisa dzekubatanidza senge lap joints uye welding yekubatanidza haigone kugutsa kukurumidza kusimudzira kweindasitiri yekuvaka maererano nemhando yekubatanidza, kunyatsoita, uye kushanda. Kuenderera mberi kwekuvandudzwa kwesimbi conical thread coupler tekinoroji kwatungamira kukuwedzera hunyanzvi muindasitiri yese uye kuenderera mberi kwehunyanzvi. Naizvozvo, simbi simbiyekubatanidza tekinorojiinonyatso kubudirira mune imwe pfungwa, uye ine hunhu hwayo kuitira kuti igone kuchinjika kune inogara ichisimukira indasitiri uye magariro maitiro. Iyo lap joint yekubatanidza nzira haigone kushandiswa pakubatanidza simbi yakakura-saizi mabara, uye welding ine zvakawanda zvinokanganisa (sezvisina kugadzikana simbi, kushomeka weldability, zvichingodaro; isina kugadzikana magetsi kana kushaya welder level; nguva Kusimba, kusakwana kugona; mamiriro ekunze uye mamiriro ekunze semhepo nemvura; zvirongwa zvekuvaka zvenzvimbo dzine zvinodiwa zvekudzivirira moto zvakanyanya; kunaka uye kukurumidza kwekubatanidza rebar).

Welding mhando haigone kuvimbiswa. Iyo mechanic yekubatanidza yesimbi simbi inogona kudzivirira matambudziko ari pamusoro uye kuratidza zviri pachena zvakanakira. Mukupera kwema1980, kuburikidza nekuunzwa kwekunze kwehunyanzvi hwekubatanidza tekinoroji, pamwe nekuenderera mberi kwekuedza kwenyanzvi dzemamwe masangano ekutsvagisa kwesainzi muChina, tekinoroji yeChina yakasimbiswa yekubatanidza michina yakagadzira nekukurumidza. Iyo mechanic yekubatanidza yakapinda matanho akasiyana ekusimudzira akadai seSleeve cold extrusion, taper threading, kushatisa tambo yakatwasuka kusvika kune yazvino inotenderedza tambo, uye tekinoroji yave yakakura uye yakagadzikana, uye mutengo wakaramba uchidzikiswa.

Zvisinei neizvi, tekinoroji yekuChina yekubatanidza tekinorojiichine imwe gap kana ichienzaniswa nenyika dzekunze. Rimwe rematambudziko akatanhamara nderekuti kurira kune imwe chete. Iyo rebar kubva pahupamhi hwe16 kusvika ku40 mm ine pitch ye2.5 mm, uye 2.5 mm pitch inonyatsokodzera dhayamita ye22 mm. Kusimbisa kubatana. Kunyangwe kuchine mikaha mune dzimwe nzvimbo, mapeji aya anodzikiswa sezvo tekinoroji yekugadzira simbi yekuChina ichiramba ichikura.

Yida yakasimbisa conical thread coupler ine zvinotevera mamiriro:

1. Hapana kutsemuka pamusoro peconical thread coupleruye shinda dzakazara uye hapana kumwe kuremara.

 2. Kuongororwa kweprofile yezino, tarisa kurongeka kwedimensional ne thread yakatwasuka plug geji.

 3. Nzvimbo dzekunze dze conical thread couplers dzemhando dzakasiyana-siyana uye saizi dzinofanira kunge dziine nhanho dzakajeka dze rebar uye madhayamita.

 4. Maburi ari kumagumo ese econical thread coupler anofanirwa kuvharwa nekavharo yepurasitiki kuchengetedza mukati makachena nekuchena.

Yida yakasimbisa simbi sleeve / rebar yakatwasuka shinda ine zvinotevera zvakanakira:

 1. Haisi kukanganiswa nezvinhu zvakawanda zvakadai semakemikari anoumbwa nesimbi, zvinhu zvevanhu, mamiriro ekunze, magetsi, nezvimwewo;

 2. Haina kusvibiswa, inosangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza, uye yakachengeteka uye yakavimbika pasina kushanda kwemoto wakazaruka;

 3. Yakasiyana-siyana yekushandiswa, inoshandiswa kune zvakasiyana-siyana zvekutarisa uye zvakafanana, zvakasiyana-siyana zvekusimbisa dhayamita yekubatanidza;

 4. Simba guru, rakagadzikana uye rakavimbika unhu;

 5. Kushanda kuri nyore, kukurumidza kwekuvaka.

Mumakore achangopfuura, China yakafambira mberi zvikuru mutekinoroji yekubatanidza yekusimbisa michina yesimbi. Simbi-yakasimbiswa conical tambo couplers anoshandiswa zvakanyanya mumapurojekiti makuru senge zvivakwa zvepamusoro-soro, mabhiriji, njanji dzinomhanya-mhanya, zvidyarwa zvemagetsi enyukireya, uye zvivakwa zvesimbi. Rebar yekubatanidza sleeves iri nyore kushanda, haina murazvo wakavhurika, yakachengeteka uye inokurumidza, uye inochengetedza zvakanyanya zviwanikwa uye manpower. Ivo vanoremekedzwa zvakanyanya muChina nepasirese, uye zvishoma nezvishoma vanotsiva yechinyakare rebar yekusunga uye welding tekinoroji.

HeBei YiDa inosimbisa simbi yekubatanidza sleeve inoshandiswa zvakanyanya mumapurojekiti makuru akadai seHong Kong-zhuhai-macao zambuko, fuqing nuclear power plant, Beijing-shanghai high-speed njanji uye Wuhan Greenland centre.
