Maitiro matsva ekugadzira piston neDTH sando
Maitiro matsva ekugadzira piston neDTH sando
Kutanga, mamiriro azvino eiyo perforator piston
Kubva pakuona kwemutoro unotakurwa nepiston, piston inoda kuve nehupamhi hwepamusoro uye kupedzisa kwepamusoro,
kuitira kuti ive nechisimbiso chakanaka chekuisa chisimbiso uye ienderane kune maitiro e-high-frequency reciprocating motion; panguva imwe,
inoda kuve neyakagadziriswa dhizaini uye yakanaka kupisa kurapwa, kuitira kuti igone kufambisa zvakanaka simba rekuita uye
ine yakakwirira kuramba kune mechanical abrasion uye kukanganisa kupikisa.
1 Piston simba dzidziso ongororo
Kuburikidza ne-hole hammer piston impact bit, munguva pfupi pfupi, kumhanya kwekufamba kwayo (saizi negwara) ine.yakachinja zvinoshamisa, mukukurumidza kuchinja kwehukuru uye kutungamira kwenguva dzose pasi pechiito chekuchinja kwe cyclical mumutoro une simba,
strain yepiston haisi iyo yakazara yunifomu dhizaini, kufamba kwehuwandu haisi iyo yakazara yunifomu kumhanya, kumhanyisa uye kumhanya zvinoparidzirwa.
muchimiro chekushushikana kwemafungu. Mukuita kwekurovera kutenderera, nyundo yakanyura inoshandisa kukanganiswa kwepiston kufambisa kushushikana.
vheyesa kudombo riri pazasi pegomba nepachibooreso kuti uone kucherwa kwedombo. Iyo piston yesando yakanyura ine shanduko
muchinjika-chikamu chimiro, umo kushushikana kwemhepo kunopararira uye kunosungirwa kuchinjirwa pakuchinjika-chikamu chekuchinja, kwete chete pamigumo yesando.
Nepo sando yechikamu chakaenzana ichiiswa pasi pekumanikidzika, shanduko-chikamu sando inoiswa kwete chete kumanikidziro ekumanikidza, asiwo kune tensile kusagadzikana.
2 inokanganisa kugadzirwa kwepiston uye kupisa kurapwa maitiro
Impact piston performance ine hukama nemaitiro ayo ekugadzira. Zvinhu zvakasiyana, maitiro ayo ekugadzira akasiyana.
( 1) yakakwira kabhoni vanadium simbi (yakadai seT10V) yekugadzira piston process nzira yekuongorora mbishi
(kemikari yakagadzirwa, micro, isiri-metallic inclusions uye kuoma) → zvinhu → kuumba → kupisa kupisa → kuongorora → kugaya.
( 2) 20CrMo simbi yekugadzira piston nzira yekugadzira → normalizing → kuongorora → machining → kupisa kupisa → jecha rinoputika → kuongorora → kukuya.
( 3) 35C Mr oV simbi yekugadzira piston nzira yekugadzira → kupisa kupisa y kuongorora ( kuoma ) → machining → carburizing → kuongorora ( carburized layer )
→ tembiricha yakanyanya → kudzima → kuchenesa → kudzika tembiricha → kuputika kwejecha → kuongorora → kukuya.
3 Piston kutadza chiitiko
Piston isimba rakaomarara mukati menyundo yakanyudzwa, zviri nyore kukuvadza zvikamu. Piston mune yakakwira-kudzvanywa gasi dhiraivha, ine yakakwira yekumhanyisa kukanganisa bit, uyezve kuburikidza
chidimbu kusvika pasi pegomba rokwe rinokanganisa simba rekufambisa. Impact process, iyo piston nehukuru uye kutungamira kwesimba ndeyekuchinja nguva nenguva, anenge zana bhaketi.
s mukati mesimba rakangoerekana rawedzera kusvika kumakumi ematani, kana kutopfuura, uyezve mushure memazana mashoma mamicroseconds, uyezve kudzokera pasi kusvika ku zero. Kuratidzwa kwenguva refu kune
inodzokororwa pakarepo simba rekuita, rinoburitsa kushushikana mupfungwa mune zvimwe zvikamu zvepiston, zvichikonzera kukuvara kwepiston, kukuvara uku kwakajairika mukuvaka.
mashandiro emichina yekukanganisa, kuitira kuti piston kutadza, senge: piston kutyoka, piston musoro kuora mwoyo, piston musoro simbi spalling.
Mukutanga kwekuedzwa, hupenyu hwekushanda hweburi-hole hammer piston hwakaderera kwazvo, kupfuura kuputsika kumwe, kunenge kutsemuka kwese kuri mudhayamita diki.
zvikamu zvepiston, zvimwe zvine longitudinalinoputika yakananga kumagumo ediki dhayamita, Mufananidzo 2 wekuputsika kwepiston yemufananidzo wemuviri. Hupenyu hwekushanda kwe
piston ichakanganisa zvakananga kuita kwesando yakanyura pachayo uye kusimudzirwa nekushandiswa kweinopinda mukati menyundo yekuchera tekinoroji, uye
zvikonzero zvekutyoka kwayo zvinofanirwa kuongororwa kubva kune yakakosha simba mamiriro episton.
Chechipiri, iyo itsva maitiro e submariner piston machining
Products
HFD Mining Tools ibhizinesi rakavakirwa pane yakazvimirira hunyanzvi, iyo yakazvipira kuvandudza kupfeka kuramba uye hupenyu hwesevhisi yeDTH bits nesando.
HFD Migodhi Zvishandiso yakabudirira kugadzira zvinhu zvakakosha zvesando dzeDTH.
1、Product Principle
Metal surface crystal remodeling TM tekinoroji ishanduko innovation musimbi pamusoro pekugadzirisa tekinoroji kubva pakuona kwegirazi kugadzirisa, kristaro.
kugadziridza, nzira yekutsvakurudza, kubviswa kwekristaro kukanganisa pamusoro pesimbi. SPIRIT's Crystal Resurfacing TM tekinoroji inogona kuderedza zvakanyanya pamusoro
roughness uye kunatsiridza kuneta simba, microhardness, abrasion resistance, corrosion resistance uye zvimwe zvinhu zvesimbi. Inovandudza zvakanyanya sevhisi
hupenyu hweDTH Hammers.
2, DTH sando piston simbi pamusoro inoburitsa mhedzisiro mitanhatu:
1) Iyo simbi yepamusoro inogona kuona nyore girazi mhedzisiro, Ra≤0.2μm.
2) Metal surface crystal remodeling, kugadzirisa zviyo.
3) Surface microhardness yakawedzera ne10% -30%.
4) Kubviswa kwekristaro kukanganisa uye kuumbwa kwekumanikidza kudzvinyirira pane simbi pamusoro.
5) Kunyanya kunatsiridza kupfeka kuramba uye kuomarara kuramba kwesimbi pamusoro.
6) Kuwedzera zvakanyanya hupenyu hwezvikamu zvekuyamura basa.
