Isishwankathelo seendlela ezisibhozo zokusetyenzwa komsonto ekufuneka uyazi xa usenziwa ngomatshini.
.Igama lesiNgesi elihambelana ne-Screw is Screw. Intsingiselo yeli gama itshintshe kakhulu kumakhulu eminyaka yakutshanje. Ubuncinci ngo-1725, lithetha "ukukhwelana".
Ukusetyenziswa komgaqo womsonto kunokulandwa umva kwisixhobo sokuphakamisa amanzi esijikelezayo esenziwe ngumphengululi ongumGrike uArchimedes ngowama-220 BC.
Ngenkulungwane ye-4 AD, amazwe aseMeditera aqala ukusebenzisa umgaqo weebholiti kunye namandongomane koomatshini bokushicilela abasetyenziswa ekwenzeni iwayini. Ngelo xesha, umsonto ongaphandle wawubotshwa ngentambo ukuya kwicylindrical bar uze ukrolwe ngokwalo phawu, ngoxa umsonto wangaphakathi wawudla ngokuyilwa ngokubethelela umsonto ongaphandle ngento ethambileyo.
Malunga ne-1500, kumzobo wesixhobo sokulungisa intambo esizotywe ngu-Leonardo da Vinci wase-Italiya, kwakukho umbono wokusebenzisa i-Screw yabasetyhini kunye negiya yokutshintshiselana ukucubungula imisonto ngeepitshi ezahlukeneyo. Ukususela ngoko, indlela yokusika imisonto ngoomatshini iye yaphuhliswa kwishishini laseYurophu lokwenza iiwotshi.
Ngowe-1760, abazalwana baseBritani uJ. Wyatt noW. Wyatt bafumana ilungelo elilodwa lomenzi wechiza lokusika izikrufu zomthi ngesixhobo esithile. Ngomnyaka we-1778, iBritish J. Ramsden yakha yenza isixhobo sokusika intambo esiqhutywa yiperi yegiya yeentshulube, esikwaziyo ukucubungula imisonto emide ngokuchaneka okuphezulu. Ngomnyaka we-1797, iNgesi uH. Maudsley wasebenzisa i-Screw yabasetyhini kunye nezixhobo zokutshintshiselana ukujika imisonto yentsimbi yeepitshi ezahlukeneyo kwi-lathe yakhe ephuculweyo, eyabeka indlela yokuqala yokujika imisonto.
Ngeminyaka yee-1820, uMaudsley wavelisa iimpompo zokuqala kwaye wafa ngenxa yokuthunga.
Ekuqaleni kwenkulungwane yama-20, uphuhliso lweshishini leemoto lwakhuthaza ngakumbi ukubekwa emgangathweni kwemisonto kunye nophuhliso lweendlela ezahlukeneyo ezichanekileyo nezisebenzayo zokucombulula intambo. Iintloko ezahlukeneyo zokuvula ezizenzekelayo zokuvula kunye neetephu ezizenzekelayo ezicuthekayo zayilwa enye emva kwenye, kwaye kwaqala ukusetyenziswa imisonto yokusila.
Ekuqaleni kweminyaka yee-1930, kwavela ukucola intambo.
Nangona iteknoloji yokuqengqeleka intambo yayinelungelo elilodwa lomenzi ekuqaleni kwenkulungwane ye-19, ngenxa yobunzima bokwenziwa komngundo, uphuhliso lwandiswa de kwayiMfazwe Yehlabathi yesiBini (1942-1945) ngenxa yesidingo sokuvelisa izixhobo kunye nophuhliso lobugcisa bokusila intambo. Ingxaki echanekileyo yokwenziwa kokungunda ikhule ngokukhawuleza.CNC ukujika inxalenye
Imisonto yahlulahlulwe kakhulu ibe yimisonto edibanisayo kunye nemisonto yokuhambisa.

Nangona kunjalo, i-rolling Thread reThread ukuba ubulukhuni besixhobo sokusebenza abudluli HRC40; ukuchaneka kwe-dimensional ye-blank iphezulu; ukuchaneka kunye nobunzima bokufa okuqengqelekayo nako kuphezulu, kwaye kunzima ukwenza idiyizi; ayifanelekanga ukuqengqeleka kwemicu ene-asymmetric tooth shape.
Ngokufa kokuqengqeleka okwahlukileyo, Umsonto unokwahlulwa ube ziindidi ezimbini: Ukuqengqeleka komsonto kunye ne-Threadthreadd.
6. Ukuqengqeleka komsonto
Iipleyiti ezimbini zokuqengqeleka ezinemisonto yamazinyo zicwangciswe ngokuchaseneyo kunye ne-1/2 pitch; ipleyiti engatshintshiyo ilungisiwe, kwaye ipleyiti eshukumayo ihamba kwi-reciprocating linear motion parallel kwipleyiti engatshintshiyo. Xa i-workpiece ithunyelwa phakathi kwamacwecwe amabini, ipleyiti eshukumayo iqhubela phambili kwaye ikhuhle i-workpiece ukuze i-plastic ikhubaze umphezulu ukwenza intambo (Umfanekiso 6 [Screwing]).
7. Ukuqengqeleka komsonto
Kukho iintlobo ezintathu ze-radial Thread roThread, tangential Thread roThread, kunye nentloko eqengqelekayo.
①I-Radial Threathreadad 2 (okanye 3) amavili aqengqelekayo anemisonto yeprofayile afakelwe kwishafti ezinxuseneyo; i-workpiece ifakwe kwinkxaso phakathi kwamavili amabini, kwaye amavili amabini ajikeleza ngendlela efanayo nangesantya esifanayo (Umfanekiso 7). [I-Radial Thread rolling]), enye yemijikelo, yenza intshukumo yokutya kweradial. Ivili elijikelezayo lijikeleza i-workpiece, kwaye umphezulu we-radially extruded ukwenza imisonto. Kwezinye izikrufu ezikhokelayo ezingadingi kuchaneka okuphezulu, indlela efanayo ingasetyenziselwa ukwenza umqulu.
②Tangential Thread roThread Eyaziwa ngokuba yiplanetary Thread roThread, isixhobo esiqengqelekayo sinevili elijikelezayo elijikelezayo eliphakathi kunye neepleyiti ezintathu ezilungisiweyo ezimile okwearc (umzobo 8 [I-Tangential Thread rolling]). Umsebenzi wokusebenza unokondliwa ngokuqhubekayo ngexesha lomsonto, ngoko ke imveliso iphezulu kunaleyo ye-Thread roThreadand radial Thread thread.
③ Umsonto uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uwafunde umsonto: Wenziwa kwileyile ezenzekelayo kwaye ngokuqhelekileyo isetyenziselwa ukusetyenzwa kwemisonto emifutshane kwisixhobo sokusebenza. Kukho i-3 ukuya kwe-4 yamavili ajikelezayo asasazwa ngokulinganayo kwi-periphery yangaphandle ye-workpiece kwintloko eqengqelekayo (Umfanekiso we-9 [Umsonto owenziwe ngokutsha]). Ngexesha lokuqengqeleka kwentambo, i-workpiece ijikeleza, kwaye intloko eqengqelekayo itya i-axially ukuze ikhuphe i-workpiece ngaphandle kweThread.
Ukuthunga imisonto
Ukusetyenzwa kwemicu eqhelekileyo ngokuqhelekileyo isebenzisa amaziko omatshini okanye izixhobo zokucofa kunye nezixhobo; ngamanye amaxesha, ukucofa ngesandla kuyenzeka. Nangona kunjalo, kwezinye iimeko ezikhethekileyo, le ndlela ingasentla ayilulanga ukufumana iziphumo ezilungileyo zokucwangcisa, ezifana nesidingo somatshini wemisonto emva kokunyangwa kobushushu bamalungu ngenxa yokungakhathali okanye ngenxa yezithintelo zezinto eziphathekayo, ezifana nesidingo sokucofa ngokuthe ngqo kwi-carbide workpieces. . Ngeli xesha, kuyimfuneko ukuqwalasela indlela yokucubungula i-pEDM.
