Izici eziyi-8 ze-Twist Drill kanye nemisebenzi yayo

Uyayazi le migomo: I-Helix Angle, I-Point Angle, onqenqemeni oluyinhloko, iphrofayili yomtshingo? Uma kungenjalo, kufanele uqhubeke nokufunda. Sizophendula imibuzo enjengokuthi: Yimuphi umphetho wesibili wokusika? Ithini i-helix angle? Bathinta kanjani ukusetshenziswa kwisicelo?

Kungani kubalulekile ukwazi lezi zinto: Izinto ezahlukahlukene zibeka izimfuno ezahlukene ethubeni. Ngalesi sizathu, ukukhethwa kwe-twist drill enesakhiwo esifanele kubaluleke kakhulu kumphumela wokumba.

Ake sibheke izici eziyisishiyagalombili eziyisisekelo ze-twist drill: iphuzu engela, umphetho oyisisekelo, usike emaphethelweni e-chise, usike bese ukhomba ukuncipha, iphrofayili yomtshingo, umnyombo we-helix.

Ukuze uzuze ukusebenza okuhle kakhulu kokusika kwezinto ezihlukile, zonke izici eziyisishiyagalombili kufanele zifaniswe.

Ukufanekisa lokhu, siqhathanisa lokhu okulandelayo okusontekile okusontekile komunye nomunye:

• Twist Drill Din 338, HSS-E
• Ukusonteka drill din 338, HSSE-CO M35
• Twist Drill Din 338, HSS 4341

I-Point Angle

I-angle yamaphuzu itholakala ekhanda le-twist drill. I-angle ilinganiswa phakathi kwalemiphetho emibili yokusika ephezulu phezulu. I-angle yamaphoyinti iyadingeka ukuhambisa ukudonsa okusontekile kokuqukethwe.

Uma lincane i-angle yamaphuzu, kube lula ukugxila kokuqukethwe. Lokhu futhi kunciphisa ingozi yokudambisa indawo egobile.

Okukhudlwana i-angle yephuzu, okufushane ukuphrinta isikhathi. Kodwa-ke, ingcindezi yokuxhumana ephakeme iyadingeka futhi ukugxila kokuqukethwe kunzima.

I-geometri kahle, i-angle encane yamaphoyinti isho imiphetho emide yokusika, kanti i-angleng enkulu yamaphuzu isho imiphetho emifushane yokusika.

Imiphetho eyinhloko yokusika

Imiphetho eyinhloko yokusika ithatha inqubo yangempela yokumba. Imiphetho emide yokusika inokusebenza okuphezulu kokusika ngokuqhathaniswa nemiphetho emifushane yokusika, noma ngabe umehluko mncane kakhulu.

I-twist dring ihlala inemiphetho emibili yokusika eyinhloko exhunywe yi-chisel edge.

Sika emaphethelweni e-chisel

Umphetho we-Cute Chisel utholakala maphakathi nethiphu yokumba futhi awunawo umphumela wokusika. Kodwa-ke, kubalulekile ekwakhiweni kwe-twist drill, njengoba ixhuma imiphetho emibili eyinhloko yokusika.

Umphetho we-Cute Chisel unesibopho sokufaka izinto ezibonakalayo futhi ucindezele ingcindezi nokuxabana kokuqukethwe. Lezi zakhiwo, ezingathandeki ngenqubo yokumba, ziphumela ekukhuliseni kokushisa kokushisa kanye nokusetshenziswa kwamandla.

Kodwa-ke, lezi zinto zingancishiswa ngokuthiwa "ukuncipha".

Ukusikeka kwephuzu nokuncipha kwamaphuzu

Iphuzu lincipha ukunciphisa umphetho we-cut clese phezulu kwe-twist drill. Ukuncipha kuphumela ekunciphiseni okukhulu kwamabutho okungqubuzana kokuqukethwe ngakho-ke ukuncishiswa kwamandla okuphakelayo adingekayo.

Lokhu kusho ukuthi ukuncipha kuyisici esinqumayo sokugxila kokuqukethwe. Kuthuthukisa ukushaywa.

Amaphuzu ahlukahlukene abukhali ahlelwe ngezimo ze-DIN 1412. Amajamo ajwayelekile kakhulu yiphuzu le-Helical (Shape n) kanye ne-Split Point (CHESH C).

Iphrofayili ye-Flue (iphrofayili ye-Groove)

Ngenxa yokusebenza kwayo njengohlelo lwesiteshi, iphrofayili yofreyimu ikhuthaza ukumuncwa kwe-chip nokususwa.

Iphrofayili ye-Groove, engcono ukumuncwa kwe-chip nokususwa.

Ukususwa kwe-chip okumpofu kusho ukuthuthukiswa kokushisa okuphezulu, okuthi ngokubuya kungaholela ekunciphiseni nasekugcineni ukwaphuka kwe-twist drill.

Amaphrofayili abanzi we-Groove afulethi, amaphrofayili athambile ajulile ajulile. Ukujula kwephrofayili ye-groove kunquma ubukhulu bokuma komgogodla. Amaphrofayili we-Flat Groove avumele ama-diameter amakhulu (aminyene) amakhulu. Amaphrofayili ajulile ama-Groove avumela ama-diameters amancane (amancanyana).

Umongo

Ubukhulu obuyisisekelo yisilinganiso sokunquma sokuqina kwe-twist drill.

Ukusonteka kwe-drive nge-core ubukhulu obukhulu (obukhulu) obukhulu bunokuqina okuphezulu ngakho-ke kufanelekile ukuthola ama-torque aphezulu nezinto ezinzima. Futhi zilungele kakhulu ukusetshenziswa kuma-drill hand njengoba zimelana kakhulu nokudlidliza namabutho alandelanayo.

Ukuze kube lula ukususwa kwama-chip kusuka ku-groove, ubukhulu obuyisisekelo banda kusuka kuthiphu ye-drill kuya e-shank.

Ukuqondisa ama-Chamfers kanye nemiphetho yesibili yokusika

Ama-chamfers emigqa emibili atholakala emigqonyeni. Amahlathi omhlaba omningi asebenza ngokungeziwe asebenza ngokungeziwe emaphethelweni aseceleni weBorehole futhi asekele ukuholwa okusontekile emgodini ovuthiwe. Ikhwalithi yezindonga ze-borehole nayo incike kwimihlahlandlela ye-Chamfers Properties.

Unqenqema lokusika lwesibili lwakha inguquko kusuka kumahlaya wokuqondisa ukuze ugcwale iphrofayili. Inika amandla futhi inquma ama-chips anamathele ezintweni ezibonakalayo.

Ubude be-Candur Chamfers kanye namaphethelo wokusika okwesibili ancike kakhulu ku-angle ye-helix.

I-Helix Angle (I-Engle Spiral)

Isici esibalulekile se-Twist Drill yi-angle ye-helix (i-angle evunguzayo). Inquma inqubo yokwakheka kwe-chip.

Ama-angles amakhulu we-helix angel ahlinzeka ngokususwa okusebenzayo kwezinto zokwakha ezithambile, ezinde. Ngakolunye uhlangothi, i-helix angles, ngakolunye uhlangothi, isetshenziselwa izinto ezinzima, eziwumfushane.

Ukusonteka kwe-drill okunama-angle amancane we-helix (10 ° - 19 °) anendawo ende. Ngokubuyisana, ukusontekela ukudonsa i-angle enkulu ye-helix (27 ° - 45 °) ube ne-rammed (amafushane) sivunguza. Ukusonteka kwe-drive nge-sherive evamile kune-angle ye-helix ka-19 ° - 40 °.

Imisebenzi yezimpawu kuhlelo lokusebenza

Uma ubheka kuqala, isihloko sokusonteka kubonakala siyinkimbinkimbi. Yebo, kunezinto eziningi nezici ezihlukanisa i-Twist Drill. Kodwa-ke, izici eziningi zincike kakhulu.

Ukuze uthole ukudonsa okulungile okulungile, ungazitholela kuhlelo lwakho lokusebenza esinyathelweni sokuqala. Incwajana ye-DIN yokushayela kanye nama-countersinks ichaza, ngaphansi kwe-DIN 1836, ukwahlukaniswa kwamaqembu wesicelo ezinhlotsheni ezintathu n, H, kanye no-W:

Kulezi zinsuku ngeke uthole lezi zinhlobo ezintathu N, H, kanye no-W Emakethe, ngoba ngokuhamba kwesikhathi, izinhlobo zihlelwe ngendlela ehlukile ukuze zisebenzise ukuwohloka okukhethekile kwezicelo ezikhethekile. Ngakho-ke, kwasungulwa amafomu akwaHybrid asunguliwe amasistimu awo wokuba amagama awalinganiswanga kwincwajana ye-DIN. E-MSK ngeke uthole kuphela uhlobo n kodwa futhi nezinhlobo Uni, utl noma i-VA.

Isiphetho kanye Nokufingqa

Manje uyazi ukuthi yiziphi izici ze-twist drill zithonya inqubo yokumba. Ithebula elilandelayo likunikeza ukubuka konke kwezici ezibaluleke kakhulu zemisebenzi ethile.

Ngokuyisisekelo, unganquma uhlelo lwakho lokusebenza kanye nokuqukethwe ofuna ukukushayela kukho.

Bheka ukuthi yikuphi ukudonsa okusolwa okunikezwayo bese uqhathanisa izici ezithile nemisebenzi oyidingayo ukuze ukwaziswa kwakho kungavuthwe.
