Kunyura - chii ichi?

The muzvigadzirwa basa achichinja hukuru uye Zvekare zvimiro zvemhashu zvakaita zvikamu hadzifaniri pasina ichi mhando pamusoro machine, vose kunyura. Kushandurwa kubva pashoko German rinoreva "nzvimbo", "kuwedzera". Kuti tive kunyatsoenderana, ndiko chichiitwa, panguva iyo inowedzera dhayamita mumakomba. Unogona kuenzaniswa reaming. Countersinking - zvokuimba oparesheni, iro rinoitwa munguva kuchifinha kuti mumakomba, kuvandudza uye kururama kwavo pamusoro.

kugamuchira makomba

Kuti zvakasimba kunzwisisa zviri kunyura, unofanira kuva pfungwa sei kuti maburi zvizere. Ngatitii preform zvakafanira vanochera buri vekirasi zvakarurama dhayamita 12 mm wechishanu.

Izvi zvinoda Drilling Machine uye 3 anoshanda chokushandisa: chibooreso, countersink uye tarisei. Mumwe nemumwe ndima idzi chakagadzirirwa kubata, nokuti reaming chibooreso, dhipuroya - kuvhiyiwa ichi zvikuru zvakafanana mumwe. Zvikurukuru pakuita rimwe workpiece achishandisa chibooreso rejeri, asi ayo dhayamita achava shoma zvikuru pane yaidiwa, vanoti hafu - 6 mm.

Ichi roughing. Next, zvinokosha kuti ream countersink dhayamita 12 mm (kupedza oparesheni). Uyezve, makirisito kuchera ichapa 7 zvakarurama kirasi.

Kuti buri 5 boka, unofanira kushandisa scan. It achapa anodiwa kukura muganhu uye kushivirira - okugadziridza uye chose buri machine. Reaming uye countersinking kazhinji ushande chete dhayamita, asi zvakasiyana kukura miganhu, uye sezvo kutsvaira inopa boka zvakarurama ezasi, ngaabvumire kuti nekutumirwa kwemauto vakasarudzwa dzakakwirira zvakarurama.

Reaming uye countersinking

Kakawanda izvi pfungwa kuvhiringidzika pamwe chete nokuti kuti vari kwazvo zvakafanana mune mazita. Zvisinei, kana kunyura - a kwacho umo countersink kutushura rose kudzika countersink kubudiswa rinonzi pamusoro.

Zvakakodzera kuumba pakadzika nokuda countersunk musoro fastening okunze (nekiyi, rivets, screws). Countersink - chishandiso chamfering kwakatosiyana countersink Maumbirwe kushanda rutivi.

Zvinhu uye nemhando countersink

Just somumwe nokuveza mudziyo, countersink iri Classified ne mhando okuvaka, chimiro uye mhando kurapwa, uyewo zvinhu izvo zvinonzi zvakaitwa.

Sezvo chishandiso ane mukuru zvakaoma, kazhinji chinoitwa pamatunhu nokukurumidza simbi Zvisinei, kazhinji kuonekwa kubva constructional doped countersink (40X) uye kabhoni (ST45) chiwanikwa,.

Kunyura - zviri rimire uye pakuchenesa pemvura, saka huchashandiswa pacharwo vakawanda rokutema kumicheto. Countersinks zvingava Precast muswe pamwe patsanurika mashizha, muswe muna chimwe, inotunga-mberi uye vanosundira-chinokosha zvikwata.

Kana ukatarira mumaonero kunyatsoshanda, ipapo, Chokwadi, modular Zviridzwa anodhura, asi upenyu hwavo zvikuru yakareba, sezvo kunogumira chakaremara zvinogona kutsiviwa.

Kureba uye dhayamita

Kubvira Drilling, reaming - muitiro rakanyatsojeka akafanana, chibooreso ikakuruma (kunyanya panyaya zononoka drills) uye countersink vane rinenge chete mamiriro. Mumwe mudziyo ane nokuveza chikamu kuti zvakananga chinoita buri chikamu.

Musiyano ndechokuti hapana countersink transverse nokuveza unopinza, asi pane kubva matatu kusvika matanhatu mazino. Its tichishanda chikamu rine geji uye okurwadzisa zvinoriumba. Kureba kunobva kudzama rechipiri reaming. The geji - a longitudinal RIBBONS pamwe nokuveza mucheto. upamhi kwavo kunobva dhayamita ari countersink (0.8-2.5 mm) uye kukwirira - 0.2-0.9 mm.

Reaming - zvokuimba oparesheni, akafanana reaming. Kana chinangwa chacho ndechokuti akaberekera gomba nekutumirwa kwemauto, ari countersink dhayamita anosarudzwa duku, vakapiwa mugove rokupedzisira pakuvakwa oparesheni. Kunze, sezvo zvaida zvakarurama pamusoro chokushandisa ichi dererei pane kuti kushanda pakuvheneka Mhedziso tsika pakati zvarakasiya kunogona zvikuru.

Mune imwe nyaya, reaming makomba - ndiwo rokupedzisira pakuvakwa inodiwa kuti zvikamu ane kubvumirawo zvimwe 11, 12 kuti kugiredhi. Ipapo chishandiso anosarudzwa yakavakirwa kusagarisana uye kuchengeterwa kusakara, uye ayo dhayamita anofanira kuenzaniswa dhayamita wetsime.

Engineering uye magadzirirwo

Kuti dhayamita mumakomba zvakafanira chakarurama sezvinobvira, ishande projecting countersink. Saka tinogona kuwana kufadza uye shoma dhayamita anodiwa mudziyo kuziva zvinhu uye nokuveza kwayo chikamu kuita dzemaitirwe rokutema ezvinhu.

Zvinokosha kuti chokuita kufadza uye zvishoma tsika - nayo kunodiwa kvalitet. Somuenzaniso, zvinokosha kuita Finish makomba countersinking musi 85 mm dhayamita pamwe Qualitet H11. Based minda makomba tolerances matafura panguva chezita kukura kubva 1 kusvika 500 neMM, nokuti unhu kirasi 11 (nokuti diameters kubvira 80 mm kusvika 120 mm) shiviriro Munda: yokumusoro ukoshi - "220", uye rezasi - "0", i.e. 85 ²²⁰ mm. The kunonyanyisa dhayamita pamusoro reams maburi havagoni kupfuudza 85,22 neMM, uye shoma - 85 mm.

Muchiitiko chino, ndeiya yakaita kushivirira - ndiwo musiyano pakati D _Max uye D _Maminitsi, i.e. ichava 0.22 mm. Kana isu kutaura nezvewanano, ipapo makomba achaparadzwa akaonekwa kuchinja dhayamita kupfuura 85,22 mm uye correctable - asingasviki 85 mm.
