Leha ho le joalo, mefuta ea li-drill bits tseo re li khethang li fapane libakeng tse fapaneng tsa ts'ebetso.Lisebelisoa tse sebelisoang hangata li kenyelletsa "twist drill", "flat drill", "centre drill", "deep drill" le "nesting drill".
Joale ke mofuta ofe oa ho cheka o sebelisetsoang ho cheka lipoleiti tsa tšepe?
Lebelo le phahameng la tšepe le khothaletsoa bakeng sa ho cheka poleiti ea tšepe.
Ho phaella moo, ha u phunya, ho itšetlehile ka bophara ba sekoti.Haeba sekoti se le seholoanyane, matla a mochine oa motlakase o lokelang ho sebelisoa a tla ba moholoanyane.
Hona joale ho na le tšepe e khethehileng ea ho phunya poleiti (eo hape e bitsoang hollow drill bit kapa Annular cutter kapa broach cutter kapa core drill kapa core cutter), e ka phunyang ka potlako haholo.
Molamu o kopanyang o ka kenngoa ka ho toba holim'a mochine oa magnetic drill, 'me lipoleiti tsa tšepe tse 20 mm li ka phunngoa ka metsotsoana e seng mekae feela.E na le melemo e totobetseng
Mochini oa tšepe oa tšepe o ka aroloa ka drill ea tšepe e phahameng ea lebelo le phahameng (HSS) le drill e entsoeng ka samente ea carbide (TCT) ho latela thepa.
Selelekela sa High Speed Steel Plate Drill(HSS core drill):
Litšepe tse lebelo tse phahameng bakeng sa seporo sa tšepe li amoheloa, tse nang le lihlopha tse peli tsa mofuta o tloaelehileng le mofuta o omileng oa metsi;Ka mefuta e fapaneng ea ho sebetsana le mefuta, geometry ea meno e nang le patented end, moralo oa karohano ea li-chip, e tsitsitseng ebile e ka tšeptjoa.
Bophara bo tloha ho 12mm ho isa ho 36mm, 'me botebo ke 25mm le 50mm;
Kenyelletso ea boro ea tšepe ea carbide (TCT core drill):
Mofuta oa ho sebetsana le mochini oa "brand" oa lefats'e o koahetsoe ka botlalo, 'me bophara ba letoto le tloaelehileng ke ho tloha ho 11mm ho isa ho 150mm.Botebo ba ho itšeha ke 35mm, 50mm, 75mm, 100mm, 150mm;
Boholo bo boholo ba letoto le ikhethileng ke 200mm, 'me botebo bo boholo ba ho itšeha ke 200mm;
E amohela lehare la carbide le kentsoeng kantle ho naha le nang le likaroloana tse ntle haholo, tse matla, tse sa sebetseng ebile li na le ts'ebetso e ntle haholo ea ho hanyetsa.Lehare le tlamahane ka matla le tiiso ea bophelo bo tsitsitseng;Moqapi oa lehare la li-geometric blade tse tharo o bonahatsa ka botlalo litšobotsi tsa matla a manyenyane a ho itšeha le setsi se setle;
Kenyelletso ea Mofuta oa Hollow Drill Shank:
Ha u ntse u khetha sekoti se sekoti se nang le boholo bo nepahetseng, mofuta oa molamu o lokela ho khethoa ho ea ka mohlala oa mochine oa magnetic.
Mefuta e akaretsang ea ho sebetsana le mefuta e kenyelletsa mefuta e 8: mofeng oa sekhutlo se nepahetseng, mofeng oa kakaretso, mofeng oa likoti tse 'ne, mofeng oa ho itšeha o chitja, mofeng o nang le khoele, mofuta oa P-mofuta oa sekhutlo se nepahetseng, mofeng oa likoti tse tharo, le sekoti se bataletseng.
Kenyelletso ea Twist Drill:
Ho feta moo, li-drill tse tloaelehileng tsa twist li ka boela tsa phunya lipoleiti tsa tšepe.
Twist drill ke sesebelisoa se sebelisoang haholo ho machining a lesoba.
Boitsebiso ba eona ka kakaretso ke tšepe ea lisebelisoa tsa lebelo le phahameng kapa alloy e thata.
E sebelisoa haholo-holo bakeng sa mechine ea ho cheka, li-lathes, li-drill tsa letsoho tsa motlakase le lisebelisoa tse ling tsa mechine ho sebetsana le li-diameter tse fapaneng tsa lesoba.
Li-drill tsa twist hangata li arotsoe ka li-drill tse otlolohileng tsa shank le li-cone shank twist.
Shank drill e otlolohileng: e loketse ho phunya lesoba le lenyenyane ka tlase ho 13.0mm, khoune kapa taper shank twist drill: e loketseng likoti tse nang le lesoba le bophara ba lesoba le torque.
Twist drill ke sesebelisoa sa machining se sebelisoang haholo ho fetisisa.Ka kakaretso, bophara bo fapana ho tloha ho 0.25 ho isa ho 80 mm.
Haholo-holo e entsoe ka karolo e sebetsang le molamu.Ho na le li-grooves tse peli tse spiral karolong e sebetsang, tse shebahalang eka ke twist, ka hona lebitso.
E le ho fokotsa khohlano pakeng tsa karolo ea tataiso le lebota la lesoba nakong ea ho phunya, bophara ba "twist drill" bo fokotseha butle-butle ho tloha ntlheng ea ho phunya ho ea ho shank, 'me bo ka sebōpeho sa khoune e sothehileng.The helix angle ea twist drill e ama haholo-holo boholo ba sekhahla sa rake ka lehlakoreng la ho itšeha, matla a lobe ea lehare le ts'ebetso ea ho tlosa chip, hangata 25 ° ~ 32 °.Spiral groove e ka siloa le ho siloa.
Karolo e ka pele ea mochini oa ho phunya e siloa ho etsa karolo ea ho itšeha ka ho bilika ho chesang kapa extrusion e chesang.Karolo e ka hodimo ea karolo ea ho itšeha ea drill e tloaelehileng ea twist ke 118, angle oblique ea bohale bo ka holimo ke 40 ° ~ 60 °, 'me lehlakoreng le ka morao ke 8 ° ~ 20 °.
Ka lebaka la mabaka a sebopeho, lehlakore le ka pele le leholo moeling o ka ntle mme butle-butle le fokotseha ho ea bohareng.
Moeli oa sefapano o na le lehlakoreng le ka pele (ho fihlela ho -55 °), le sebetsang e le extrusion nakong ea ho cheka.E le ho ntlafatsa ts'ebetso ea ho itšeha ea twist drill, karolo ea ho itšeha e ka theoa ka libopeho tse fapaneng ho ea ka thepa ea thepa e sebetsoang (joalo ka sehlopha sa ho phunya).Li-drill tsa twist li na le mefuta e 'meli ea shank: shank e otlolohileng le taper shank.Ea pele e tlanngoe ka har'a chuck ea ho phunya ha ea morao-rao e kenngoa ka lesoba la taper la spindle kapa tailstock ea sesebelisoa sa mochini.
Ka kakaretso, li-drill tsa twist li entsoe ka tšepe ea lebelo le holimo.Li-drill tsa twist tse nang le li-carbide tse kentsoeng kapa meqhaka li loketse ho sebetsana le tšepe e entsoeng ka tšepe, tšepe e thata le lisebelisoa tse seng tsa tšepe.Li-drill tse nyane tse entsoeng ka samente tsa carbide li sebelisetsoa ho sebetsana le likarolo tsa lisebelisoa le liboto tsa potoloho tse hatisitsoeng.
Kenyelletso ea Step Core Drill:
Mehato ea mantlha, eo hape e tsejoang e le ho cheka mohato kapa pagoda, e sebelisoa haholo bakeng sa ho cheka lipoleiti tse tšesaane tsa tšepe ka har'a 3mm.
Boro e le 'ngoe e ka sebelisoa ho e-na le ho phunya hangata.Likoti tse nang le li-diameter tse fapaneng li ka sebetsoa kamoo ho hlokahalang, 'me likoti tse kholo li ka sebetsoa ka nako e le' ngoe ntle le ho nkela mekoti ea ho phunya le ea ho cheka sebaka.
Ho ea ka sebopeho sa groove sa sehlahisoa, se ka aroloa ka groove e otlolohileng, spiral groove le groove e chitja;
Hajoale, boro ea mehato eohle e entsoe ke CBN ho sila ka botlalo, haholo-holo ho entsoe ka tšepe e lebelo le holimo, alloy e thata, joalo-joalo, e nang le litlhoko tse phahameng tsa ts'ebetso.Ho ea ka maemo a fapaneng a ts'ebetso, ho roala ka holim'a metsi ho ka etsoa ho lelefatsa bophelo ba sesebelisoa le ho matlafatsa nako ea sesebelisoa.
Li-drill tsa rona li entsoe ka tšepe e matla haholo e lebelo le holimo.
Bophara ba sehlahisoa bo tloha ho 4mm ho isa ho 40mm.
Motsoako oa mehato o tloha ho mehato e 4 ho isa ho mehato e 13.
Ho na le mefuta e 'meli ea li-grooves tsa spiral le li-grooves tse otlolohileng.
E loketse ho cheka le ho tsosolosa tšepe, tšepe e entsoeng ka tšepe, tšepe e sa hloekang le lisebelisoa tse ling;
Ho sila ka mokhoa o nepahetseng ka lisebelisoa tsa othomathike;Mokhoa oa ho roala o ka khethoa.
Ka hona, ho bohlokoa hape ho khetha karolo e ntle ea ho phunya bakeng sa ho cheka poleiti ea tšepe.
Empa u se ke ua tšoenyeha.Haeba u na le lipotso, ka kopo ikutloe u lokolohile ho ikopanya le rona.
Re lula re itokiselitse ho u araba lipotso leha e le life.
Re na le sehlopha sa litšebeletso tsa litsebi le sehlopha sa tlhahiso.Ho sa tsotelehe hore o odara boholo bo tloaelehileng kapa o hloka ho itlhophisa, re tla u fa letoto le felletseng la lits'ebeletso tse nahanelang.
Rea u amohela ho potso ea hau ka nako efe kapa efe!
