Self-tapping sikuruu: zviri kupi zvinoshanda

Izvi mhando fastening zvinhu zvakadai screws, kushandiswa kwose kwose. Zvakaoma kufungidzira zvavaigona kutsiviwa kana zvakakodzera. Zvinokosha zvakaisvonaka uye chenjera Threaded fasteners ambotirega zvikuru nyore Volt kupinda pose zvinhu pakubhadhara siyana uye thicknesses. Screw - haisi shamhu STRUCTURAL nhengo uye zvokunze shinda, kazhinji rinoshandiswa kubatanidza mazano akasiyana-siyana simbi. zvikamu zvose izvi mhando akakamurwa kugadzira vogadzirisa, zvichienderana nzira chikumbiro.

anoshandiswa Self-tapping screws zvikuru zvikuru, vari kushandiswa mumaindasitiri zhinji, asi dzakawanda fasteners izvi kudiwa mune zvokuimba mapurani. High kuvaka unhu, pasi nguva cost, nyore kuwedzera kwokudiwa nokuda screws. Vanogona Volt kupinda chero, kunyange nzvimbo kure, kushandisa nati hakusi zvakakodzera. Kunze, hazvina zvakafanira kuti buri, zvakananga panguva ungano aumbwa tisingatungamirirwi.

Muzviitiko zvizhinji kuzvipira tapping sikuruu rinoshandisirwa nokuti unobva zvivako zvakaitwa nezvinhu zvakadai yakaderera kabhoni simbi, aruminiyamu alloys nezvemhangura epurasitiki. Kutanga kubva zita, hazvina zvakafanira kufunga kuti sikuruwa anokwanisa kucheka acho, izvo zviri richibatanidza. Zvinogona kukonzera mapurasitiki deformation nokutsikirira simbi kana mupurasitiki.

Standards GOST 1478-93 uye GOST 2702-93 anoita risanyatsobuda ayo uye kugadzirwa kwezvinhu. Magadzirirwo pamusoro kwakakurudzira screws pamwe countersunk denderedzwa musoro uye ari mukuru chimiro. Screws iripo pamwe kuri kuitwa Phillips uye humburumbira musoro. Self-tapping sikuruwa ane zvizhinji kunze kweaya akanyorwa marudzi, vari kuwanikwa vaine shaped musoro, flange, nyeredzi-vakadzingwa. Zvisinei, pakupedzisira matatu screws muna Russian Federation zvisina kushandiswa, nekuti havana mitemo. Kunyange kana toreva kuvaka unhu, vane zvakawanda mberi kupfuura mwero screws.

Self-tapping sikuruu, yomumwe itsva kwemarudzi, haagoni kushandiswa mune Russian kugadzirwa. Chikonzero iri disparity pakati kukura neshinda. Chokwadi chokuti helical fasteners pamwe nyeredzi-nemhepo, shaped musoro uye flange, kunyange kupfuura zvipfuwo, asi vane yakasiyana zvachose shinda. Mukuwedzera, havaiti dzinoenderana pari dzinoshanda zvinodiwa zvitatu wedare iri risanyatsobuda uye kugadzirwa kwezvinhu. Magadzirirwo uye kukura screws uye regai zvinoenderana nemitemo Russian.

International Standard ISO 1478-2005 akatotanga azviwanira chimiro idzva, inosanganisira kugadzirwa uye kushandiswa screws ane woita magumo. Zvichida nokukurumidza kuzvipira tapping sikuruu vachaonekwa Russia, uye ndichaita kutorawo zvakakodzera mitemo. It yagara aronga dzifambirane zvinodiwa zvose Russian kuita dzakawanda nemitemo.

Kana kusarudza sikuruwa Magadzirirwo zvakakodzera kutanga kubva zvinhu izvo vanoda chokuedza, Ukobvu uye anodiwa kudzama mugomba. Zvichienderana mhando nhau, zvose screws okuzvifunga tapping akakamurwa kwakakurudzira, electroplating uye dema.
