Mai Rike Kayan Aikin HSK
A cikin duniyar sarrafa injina wanda ke ƙoƙarin samun ingantaccen inganci da daidaito, mai riƙe kayan aikin HSK yana jujjuya komai cikin nutsuwa.
Shin kun taɓa samun damuwa ta hanyar girgizawa da al'amuran daidaito yayin aikin niƙa mai sauri? Kuna marmarin kayan aiki wanda zai iya fitar da cikakken aikin na'urar? Mai riƙe kayan aikin HSK (Hollow Shank Taper) shine ainihin maganin wannan.
A matsayin ainihin tsarin riƙe kayan aiki na 90s wanda Jami'ar Fasaha ta Aachen ta Jamus ta haɓaka kuma yanzu matsayin duniya (ISO 12164), HSK a hankali yana maye gurbin masu riƙe kayan aikin BT na al'ada kuma ya zama zaɓin da aka fi so a cikin fagage na injina mai sauri da inganci.
I. Kwatanta tsakanin mariƙin kayan aiki na HSK da mai riƙe kayan aikin BT na al'ada (Fa'idodin Babban fa'ida)
Mai riƙe kayan aikin HSK/BT
Babban fa'idar mariƙin kayan aiki na HSK ya ta'allaka ne a cikin keɓantaccen ƙirar "hannun mazugi mai ɗorewa + ƙarshen fuskar fuska", wanda ke shawo kan manyan lahani na masu riƙe kayan aikin BT/DIN na gargajiya a cikin injina mai sauri.
| Peculiarity | HSK kayan aiki mariƙin | Mai riƙe kayan aikin BT na gargajiya |
| Ƙa'idar ƙira | Shortan gajeriyar mazugi (taper 1:10) + Ƙarshen fuska mai fuska biyu | Tsayayyen mazugi (taper 7:24) + lamba mai gefe guda na mazugi |
| Hanyar matsawa | Fuskar conical da fuskar ƙarshen flange a lokaci guda suna haɗuwa da babban haɗin shaft, yana haifar da matsananciyar matsayi. | Kawai ta hanyar samun saman conical a lamba tare da babban shaft, yana da matsayi guda ɗaya. |
| Tsauri mai sauri | Maɗaukakin ƙarfi. Wannan saboda ƙarfin centrifugal yana sa mai riƙe kayan aiki na HSK ya riƙe kayan aiki da ƙarfi, yana haifar da karuwa a cikin ƙarfinsa maimakon raguwa. | Talakawa. Ƙarfin Centrifugal yana haifar da babban rami don faɗaɗa kuma saman mazugi don sassauta ("babban shaft faɗaɗa" sabon abu), yana haifar da raguwa mai yawa a cikin tsauri. |
| Maimaita daidaito | Maɗaukakin girma (yawanci <3 μm). Ƙarshen fuskar tuntuɓar yana tabbatar da tsayin daka na axial da radial repeatability daidaito. | Kasa. Tare da mating na conical kawai, daidaito yana da wuya a yi tasiri ta hanyar lalacewa na conical saman da ƙura. |
| Saurin canza kayan aiki | Da sauri sosai. Shortan gajeren zane, tare da ɗan gajeren bugun jini da canjin kayan aiki mai sauri. | Sannu a hankali. Dogon tsayin daka yana buƙatar tsayin bugun fil. |
| Nauyi | Ya yi ƙasa da nauyi. Tsari mara kyau, musamman dacewa don aiki mai sauri a cikin biyan buƙatun don ɗaukar nauyi. | Mai riƙe kayan aikin BT yana da ƙarfi, don haka ya fi nauyi. |
| Gudun amfani | Ya dace sosai don aiki mai sauri da ultra-high-gudun (> 15,000 RPM) | Yawancin lokaci ana amfani da shi don ƙirar ƙananan sauri da matsakaici (<15,000 RPM) |
II. Cikakken Fa'idodin Mai Rike Kayan Aikin HSK
Dangane da kwatancen da ke sama, ana iya taƙaita fa'idodin HSK kamar haka:
1.Extremely high tsauri rigidity da kwanciyar hankali (mafi core amfani):
Ka'ida:Lokacin juyawa a babban gudun, ƙarfin centrifugal yana haifar da babban rami don faɗaɗa. Ga masu riƙe da kayan aikin BT, wannan yana haifar da raguwar wurin hulɗa tsakanin farfajiyar conical da babban shaft, har ma ya sa a dakatar da shi, yana haifar da rawar jiki, wanda aka fi sani da "faduwa kayan aiki" kuma yana da haɗari sosai.
Maganin HSK:A m tsarin naHSK kayan aiki mariƙinzai ɗan faɗaɗa ƙarƙashin aikin ƙarfin centrifugal, kuma zai dace sosai tare da faɗaɗa ramin sandal. A lokaci guda, fasalin tuntuɓar fuskarsa na ƙarshen yana tabbatar da tsayayyen matsayi na axial ko da a babban saurin juyawa. Wannan sifa ta "mafi ƙarfi yayin da yake jujjuyawa" ya sa ya fi tsauri fiye da masu riƙe kayan aikin BT a cikin injina mai sauri.
2. Matsakaicin matsakaicin matsakaicin matsayi na maimaitawa:
Ka'ida:Fuskar ƙarshen flange na mariƙin kayan aiki na HSK yana haɗe kusa da ƙarshen fuskar sandal. Wannan ba wai kawai yana samar da matsayi na axial ba amma har ma yana inganta juriya na radial. Wannan "ƙunƙwasa biyu" yana kawar da rashin tabbas da ke haifar da tazarar daɗaɗɗen shimfidar wuri a cikin mariƙin kayan aikin BT.
Sakamako:Bayan kowane canji na kayan aiki, runout ɗin kayan aikin (jitter) yana da ƙanƙanta da kwanciyar hankali, wanda ke da mahimmanci don cimma ƙarshen saman ƙasa, tabbatar da daidaiton girman, da tsawaita rayuwar kayan aikin.
3. Kyakkyawan daidaito na geometric da ƙananan girgiza:
Saboda ƙayyadaddun ƙirar ƙira da madaidaicin tsarin masana'anta, mariƙin kayan aikin HSK na zahiri yana da kyakkyawan aikin ma'auni mai ƙarfi. Bayan jurewa gyare-gyaren ma'auni mai ƙarfi (har zuwa G2.5 ko mafi girma matakan), yana iya daidai cika buƙatun niƙa mai sauri, rage girgiza har zuwa mafi girma, don haka samun babban ingancin madubi-kamar tasirin saman.
4. Gajeren kayan aiki canza lokaci da mafi girman inganci:
Ƙirar 1:10 gajeriyar ƙira ta HSK tana nufin cewa nisan tafiya na kayan aiki a cikin ramin spindle ya fi guntu, yana haifar da saurin canjin kayan aiki. Ya dace musamman don sarrafa hadaddun workpieces tare da babban adadin kayan aiki da kayan aiki akai-akai sauye-sauye, yadda ya kamata rage lokacin taimako da haɓaka ingantaccen kayan aikin gabaɗaya.
5. Yafi girma (ga samfura irin su HSK-E, F, da sauransu):
Wasu nau'ikan HSK (kamar HSK-E63) suna da ƙaƙƙarfan ƙaƙƙarfan ƙaho, wanda za'a iya tsara shi azaman tashar sanyaya ta ciki. Wannan yana ba da damar mai sanyaya mai ƙarfi mai ƙarfi don fesa kai tsaye ta cikin ɓangaren ciki na kayan aikin kayan aiki akan yankan gefen, yana haɓaka ingantaccen aiki da iyawar guntu mai zurfin sarrafa rami da sarrafa kayan aiki masu wahala (kamar alloys titanium).
III. Yanayin aikace-aikacen Mai riƙe kayan aikin HSK
Mai riƙe kayan aikin HSK ba duka manufa bane, amma fa'idodinsa ba za a iya maye gurbinsa ba a cikin al'amura masu zuwa:
Machining high-gudun (HSC) da ultra-high-speed machining (HSM).
Biyar-axis daidai machining na wuya gami/taurare karfe molds.
Babban madaidaicin juyawa da niƙa haɗa cibiyar sarrafawa.
Filin sararin samaniya (ayyukan sarrafa kayan aikin aluminum, kayan haɗin gwiwa, gami da titanium, da sauransu).
Na'urorin likitanci da masana'anta daidaitattun sassa.
IV. Takaitawa
Amfanin daHSK kayan aiki mariƙinZa a iya taƙaita shi kamar haka: Ta hanyar ƙirar ƙira ta "ƙananan gajeriyar mazugi + ƙarshen fuska dual lamba", yana warware ainihin matsalolin masu riƙe kayan aikin gargajiya, kamar raguwar tsauri da daidaito a cikin yanayin aiki mai sauri. Yana ba da kwanciyar hankali mai ƙarfi mara misaltuwa, daidaiton maimaitawa da babban aiki mai sauri, kuma shine zaɓin da babu makawa ga masana'antun masana'antu na zamani waɗanda ke bin inganci, inganci da aminci.
