Nhanganyaya uye tarisiro yekushandisa ye hollow drill

Hollow drill bits (multi-edge steel plate drills, inozivikanwawo sema core drill) mabhiti anodhirowa ekucheka kwakawanda-kumucheto kwedenderedzwa.Iyo dhayamita yekuchera inotangira pa12mm kusvika 150mm.Iwo anonyanya kushandiswa kuchera simbi zvinhu, senge simbi chimiro engineering uye njanji yekufambisa., mabhiriji, ngarava, kugadzira michina, aerospace uye mamwe maburi ekugadzirisa maburi, kuita kwayo kudhiraivha kuri nani kupfuura tsika.al-two-edged twist drill, ine hunhu hwepamusoro-soro kuchera, chiedza uye kushanda-kuchengetedza kuchera, multi-edged simbi plate drill uye magnetic seat drill Chishandiso chekufananidza chinogona kuita multi-directional drilling yemabasa makuru ekushanda.Iko kushanda kwacho kuri nyore uye kunochinjika, kupfupisa nguva yekuvaka, uye yave yekutanga sarudzo chishandiso chekuchera uye annular groove kugadzirisa zvemazuva ano simbi simbi.

1.Kufurira pakuchekaEdit Broadcast?

Iyo hollow drill bit igomba rekugadzirisa chishandiso chakanyatsokodzera maturusi anotakurika.Nekudaro, sezvo nzira yekugadzira yezviboorero isina kuoma yakaoma uye haigone kugadzira maburi mapofu, haawanzo kushandiswa mukucheka simbi.Ivo vanowanzo shandiswa chete kana kugadzirisa kuburikidza nemakomba dhayamita hombe kana anokosha simbi workpieces kana kana simba drilling midziyo shoma..Kubva ipapo are no standard products for hollow drill bits, akawanda maburi ekubooresa anoshandiswa kugadzira zvakakosha zvinhu zvinoda kugadzirwa isu pachedu.

Back angle effect

2.Effect of rakeangle pakucheka simba?

Shanduko mune rake angle inozokanganisa dhigirii re deformation ye chip zvinhu, nekudaro zvichikonzera shanduko mukucheka simba.The greter the chip deformation, iyo yakakura simba rekucheka;iyo diki deformation yechip, iyo idiki simba rekucheka.Kana iyo angle angle yachinja muhuwandu hwe0 ° kusvika 15 °, iyo yekucheka simba rekugadzirisa coefficient inoshanduka muhuwandu hwe1.18 kusvika 1.

3.Kufurirwa kwekona yerakepakusimba kwechibhorani?

Paunenge uchiwedzera iyo angle angle ye drill bit, iyo simba uye kupisa kupisa vhoriyamu yetipi rekushandisa inoderedzwa, uye zvinozokanganisawo kushushikana pane chishandiso tip.Kana kona yerake iine kukosha kwakanaka, tepi yekushandisa inoiswa pasi to tensile stress;kana iyo angle angle iine kukosha kwakashata, iyo tipi rekushandisa iri pasi pekumanikidza kudzvinyirira.Kana iyo angle angle yakasarudzwa yakakura kwazvo, kunyangwe kupinza kwechibhorani kuchigona kuwedzera uye simba rekucheka rinogona kuderedzwa, kushushikana kwekunetseka pachombo chekushandisa kuchave kwakanyanya, simba retipi rekushandisa richadzikiswa, uye ichatsemuka nyore nyore.Mukucheka bvunzo, madhiri mazhinji akakuvadzwa nekuda kwekunyanyisa rake angle.Zvisinei, nekuda kwekuoma kwepamusoro uye kusimba kwezvinhu zvinofanira kugadziriswa, uye kuderera kwakadzika kwegomba guru uye muchina wose weiyo inotakurika yekuchera rig, kana iyo rake angle yakasarudzwa idiki, kuwedzera kwesimba rekucheka panguva yekuchera. ichaita kuti shaft huru izununguke, uye mavibrations ari pachena achaonekwa panzvimbo yakagadzirwa nemichina.mitsetse, kusimba kwechibooreso chinozoderedzwawo.

5.Effect pakucheka permance

Kuwedzera iyo yekubvisa angle kunogona kuderedza kupokana pakati peiyo flank uye yekucheka zvinhu uye kuderedza extrusion deformation yemuchina wakagadzirwa.Nekudaro, kana iyo angle yekubvisa yakakurisa, iyo blade simba uye kupisa kwekupisa simba kuchaderedzwa.

Saizi yekona yekuyamura inobata zvakananga kusimba kweiyo drill bit.Munguva yekuchera, nzira huru dzekupfeka dzezviboorero zvimecha zvemichini nekupfeka kwekuchinja kwechikamu.Tichifunga nezve mechanical abrasion uye kupfeka, kana hupenyu hwekucheka huripo, iyo yakakura yekona yekuchenesa, iyo yakareba nguva yekucheka iripo;tichifunga nezvekuchinja kwechikamu kupfeka, kuwedzera kwekona yekuchenesa kunoderedza kupisa kwekupisa ability of the drill bit.Mushure mekunge chibooreso chapfekwa, sezvo nzvimbo yekupfeka paflank ichiwedzera zvishoma nezvishoma uye simba rekucheka rinowedzera zvishoma nezvishoma, kupisa kunokonzerwa nekukwenya kunowedzera zvishoma nezvishoma, zvichiita kuti tembiricha yekudonha ikwire.Kana tembiricha yakwira kusvika ku drill bit phase transition tembiricha, dhiri rinobva raonekwa Pfeka nekukurumidza.

6.Effect yekurodzaprocess

Iyo hollow drill bit inoshandisa shoma huwandu uye batch yekugadzirisa idiki.Naizvozvo, idzo nyaya dzetekinoroji dzinofanirwa kutariswa paunenge uchigadzira dhiri, uye kugadzirisa uye kurodza kunofanirwa kuwanikwa neyakajairwa machining michina uye maturusi akajairwa zvakanyanya sezvinobvira.Chips inoyerera ouion performance.Munguva yekubuda kunze, machipisi anosvinwa uye anokwizwa nereki kumeso, zvichikonzerakuwedzera deformation.Simbi iri pazasi pe chip inoremara zvakanyanya uye inotsvedza ichitevedza reki kumeso, zvichiita kuti pasi pechipi chirebe uye kugadzira akasiyana akamonereka maumbirwo.Paunenge uchishandisa buri rekuboora maburi, unoda kuti machipi achekwe kuita machipisi kana mitsetse kuitira kuti chip chibviswe.Kuti zvive nyore kugadzirisa uye kurodza, chiso cherake chinofanirwa kugadzirwa senzvimbo yakatsetseka isina chip breaker.Iyo raki yepamusoro haidi kudzoserwa pasi panguva yekushandiswa.Iyo yeflank pamusoro pehollow drill bit ndiyo iri nyore kugaya uye zvakare inzvimbo ine kukurumidza kupfeka mwero.Naizvozvo, kurodza kwegomba rekubooresa kunowanikwa nekurodza nzvimbo yeflank.Iyo yechipiri flank surface yakakamurwa kuita yemukati yechipiri flank surface uye yekunze yechipiri flank surface.Kubva pakuona kwekugadzika, hazvisi nyore kudzorera mukati uye kunze kwekunze kwekubatsira mativi, saka nzvimbo dzekubatsira dzinofanirwa kugadzirwa kuti dzirege kudzokororwa.

7.Kucheka mvura uye drillbits

Chinhu chikuru chehollow drill bit ndechokuti mukati megomba harina kutemwa panguva yekugadzirisa.Naizvozvo, iyo yekucheka huwandu hwegomba drill bit yakaderera zvakanyanya pane iyo ye twist drill, uye inodiwa yekudhirowa simba uye kupisa kunogadzirwa panguva yekucheka zvakare kudiki.Pakuchera ne-high-speed steel hollow drill bits, nokuti tembiricha yenzvimbo yekugadzira ine simba guru pakuoma kwechibhorani, chinotonhodza chinofanira kushandiswa kutonhora pasi panguva yekuchera (kana pasina chinotonhodza chinoshandiswa, chibooreso. Kupfeka zvishoma kuchava kunyanya kuchinja kwechikamu uye nekukurumidza pakutanga. kupfeka).Pakutanga, isued zvekunze pfapfaidzo kutonhora.Zvisineyi, nekuti chiteshi chekubooresa chinogadziridzwa munzira yakachinjika, zvinonetsa kuti chinotonhodza chipinde nechekumucheto kwechibhorani.Iyo inotonhorera inoshandiswa yakakura uye kutonhora kwacho hakuna kunaka.Iyo drill rig spindle structure yakagadziridzwa patsva kuti ichinje kunze kutonhora kwepfapfaidzo kuita kutonhora kwemukati.Iyo inotonhorera inowedzerwa kubva pakati pe hollow drill bit, kuitira kuti inotonhorera isvike zvakanaka chikamu chekucheka cheiyo drill bit, nekudaro zvakanyanya kudzikisira kutonhora nekunatsiridza Kutonhodza maitiro.
