Trapezoidal thread - da kaddarorin da kuma hanyoyin da sabon

A mafi yadu amfani da rectangular da trapezoidal thread thread, suna amfani a yi na wani iri-iri sukurori, misali da spindles na inji kayan aikin, presses da sukurori daban-daban dagawa na'urorin, kazalika da tsutsa giya.

Idan thread yana da wani rectangular profile a cikin wani nau'i na murabba'i mai dari, da trapezoidal thread yana da nau'i na wani equilateral trapezoid. Wannan zare iya samun profile kwana na wanda shi ne daidai 15,24,30 da 40 digiri. Lokacin aiki, da dunƙule da ciwon da na halitta gogayya sojojin da aka sa ta gaban lubricants da kuma surface roughness na kayan da yin sama da sassa kazalika da girma na kwana profile. Idan rectangular thread wanda profile kwana ne sifili, akwai kananan gogayya, da trapezoidal thread lashe a cewa tana radial gibba iya ƙaddara saukowa talakawan diamita, alhãli kuwa a cikin rectangular aka tsare a cikin matsanancin ko ciki diamita.

Idan kwatanta waɗannan zaren cikin sharuddan da wuya daga cikin aiwatar da su, da trapezoidal thread ne sauki zuwa tsirar, sabili da haka amfani da mafi sau da yawa. Mafi sau da yawa an yi shi da wani kwana profile 30 °.

Trapezoidal thread yana da wani sabon tsari ne kusan kama da yi na rectangular. Akwai wasu siffofin na yankan, wanda ya dogara a kan girman da surface gama da kuma daidaito.

Akwai hanyoyin da dama na yankan da kayyade irin thread.

Tapping daya abun yanka:

• Metering ne da za'ayi da workpiece huda domin fita tsagi abun yanka.
• daidai da data kasance abin kõyi za'ayi wasa kammala abun yanka.
• za'ayi lafiya gyara kayan aiki da kuma ta Anchorage, yayin da shi dole ne su kasance a kan cibiyar layi da kuma kasancewa a layi daya da axis na thread sabon;
• Kafa up da na'ura da kuma abinci abun yanka na yankan da thread.
• ne bari profile samu ta hanyar yin amfani da samfuri, da matsakaita diamita na thread.

Tapping uku masu saro:

• workpiece shiri ne da za'ayi.
• uku wasa ruwa - slotted mike, slotted kuma kunkuntar profile;
• gudanar grooving kayan aiki da kafuwa da kuma AMINCI su kayyade. Dangane da kwana na hawan, suna shirya ko dai perpendicular ga bangarorin da helical tsagi ko thread layi daya da axis kuma suna da tsawo na cibiyar line.

A wasu masana'antu da shi ya zama mai tartsatsi ne wadannan da hanyar da kerarre sukurori da trapezoidal thread:

• yi commissioning na kayan aiki don wannan aiki.
• sako tsagi aka yi har zuwa rabin da ake so zurfin ta wajen wani grooving kayan aiki;
• da ake ji kunkuntar Slotted abun yanka, kai kara yankan GROOVES zuwa ƙurewar diamita size.
• yin amfani da wani profile abun yanka, za'ayi karshe sabon trapezoidal thread.
• wani rajistan shiga na aikin yi, wanda amfani da thread ma'auni, kuma template.

Saboda haka, mun dauke da babban hanyoyin da za a yi irin wannan thread. Yanzu bari mu duba a daki-daki, yadda aikin da aka yi da kusan yankan wani trapezoidal thread:

1. Wajibi ne a shirya preform for ce irin aiki.
2. Wadannan da juna na aiki wajibi ne don kaifafa da profile roughing, kammala da grooving cutters.
3. Gudanar da duk dole gyara na kayan aiki domin yin irin wannan aiki.
4. Ta wajen da farko profiled abun yanka 85% na zurfin yanka a cikin wani trapezoidal tsagi.
5. Don aiwatar da tsagi kasa na tsagi abun yanka.
6. A karshe trimming da sabon bangarorin samu profile.
7. Duba tare da samfuri da kuma ma'auni ingancin da aikin yi.

Kamar yadda ka gani, duk abin da yake sarari da kuma sauƙi realizable.
