Machine Broaching: He Arotake, tauira, ngā, ngā āhuatanga o te whakamahi

Ko faufaa rerekē i te taputapu, i mahi i nga mahi o kuru, mira, chamfering me te tōtika i te pūrere broaching mihini. I roto i tenei tikanga o te mahi aunoa kia hāngai ki te whakahaeretanga o tukatuka i runga, Heoi, he rerekē te parau tumu o te whakarato kaha i roto i tenei take. I roto i te tahi mau āhuatanga, whakarato broaching mīhini mahi teitei, engari e kore e hanganga āhuatanga tukua tona whakamahi i roto i hinonga i roto i kahui.

mōhiohio General e pā ana ki ngā mīhini broaching

hangarau kume mo tona parau tumu o te pānga aunoa hāngai ki te momo tuku iho, me te nuinga noa o te taputapu tukatuka whakarewa. takoto te rerekētanga i roto i te tikanga mahi ratou i tenei mahi. Hei tauira, ki te mīhini broaching whakapae ki te tika tiketike hapai i ngā papa ā-o workpieces. Kei te whakamahia i tēnei taputapu mō te hanga chamfers i roto i nga wahi motuhake uaua.

E mea pinepine totoro mahi i roto i te aho-production noa ko te taahiraa ahumahi whakamutunga e whai ake nei i te momo nui atu noa o te machining i mira countersinking ranei. Ko tētahi atu āhuatanga e rerekē broaching mīhini, ko te whakamahi o ngā āhuatanga kotinga motuhake. Tenei broach e mahi hāngai mahi pūkaha i runga i te rauemi pera-ka karanga.

āhuatanga hangarau

Ko tētahi o nga drawbacks o enei mihini whakaaro te āhuatanga. Tenei te tikanga elongate pūhara, kei ai te te workpiece. Ko nga āhuatanga ahu i runga i toharite e pā ana ki te 2 m te roa, 0.5 m te whanui, me te 1.5 m te teitei. Heoi, kia rerekē te whirihoranga - aua, rerekē i roto i te rahi. Ko te papatipu, ko te pā ana ki 500 kg, na te aroaro o ka kore nui ake i te whakarato i te taahiraa turanga pono te tāutanga. Mai i te hi'oraa mahi, he mea nui, me te kukume tere, tukatuka ie. Hei tauira, he mīhini broaching i te kamupene "hononga ngāwari" i roto i te SGP.12.35 whakarerekē whakarato te auau mahi 220 mm / min o. I roto i te mau parau te tahi atu, e taea kotahi taputapu meneti mahi he roa atu i te 20 cm te mata i roto tapahia. Tenei he mea utu ki te tango ki pūkete te rohe tukatuka mōrahi, pera i roto i te nuinga o te wā ko hangarau Kāore te whakatinanatanga o te rārangi tarai ano i roto i te huarahi e rua. Ko te roa toharite o te ratonga kotahi rerekē i 4 ki te 5 m.

momo

Te wehe whakapae, poutū, me te tonu whakarerekē broaching. Ko te tuatahi, kua tuhia kē rerekē tapatahi hanganga, na ko reira e tika ana ki te mahi i ngā mahi noa i runga i te hanganga o tika motu rārangi ki te tahua rerekē i roto i te kōtaha. pūrere uaua i roto i tona mīhini broaching poutū. Tenei, i roto i te ngako, i te pūtake whakapae taua, engari anake tāuta i roto i te tūnga poutū, tuku reira maha ngā painga. Tuatahi, te whakakore i te mōrea o te sagging broaches roa, a tuarua, ko reira taea ki te whakapiki ake i hua mā te whakawhänui i te raina production. Ki te whakaaro ki te mīhini, he totoro tonu, kei te nuinga whakamahia ratou mo tukatuka i roto i te papa o waho. E kitea e ratou i te mahi teitei me te kaha ki te reni ratonga i roto i te hanga nui-tauine.

Hea whakamahia te mīhini te?

tukatuka pū broach ai nga whakaritenga ritenga o nga hua. Nä, e kore te whakamahi o te hua oti ko te noa tino. Hei tauira, kei te whakamahia ratou i roto i te hanga, me te whakamahine o ngā pū. Hoki taua ngā mahi e whakamahia mira, me te broaching mihini, me e hua kahiwi o pū mīhini me ngā pītara. Ano hoki e whakamahia ana i tēnei mīhini i roto i te hanga o pūkete matatini mutu waho i roto i te tapahi keyways me splines, me te whakatika Tapamaha me porotakaroa rua. He āhuatanga noa o ngā momo katoa o broaching machining e ïa whai wāhitanga ki motu ahua, a i roto i ngā āhuatanga uaua. I tua atu, ka taea te whakamahi i te mīhini mō te whakarewa-kore, me hoki ngā rauemi totoka. Ko te meka Ko e te processability o ngā pātea atu ki nui haere ngā āhuatanga pakeke, me te pakeke o te mahi aunoa whakaritea e nga mea timatanga, i.e. broach. A kia whai ratou ratou āhuatanga rerekē.

Manufacturers me tauira

He whānui o horo'a ngā, te kamupene "Giant." I roto i tona whānui ngā whakarerekētanga broaching mihini 7A523, 7A612, 7555 me etahi atu. Rerekē te tauira mā te mahi i te tere tukatuka, peia kaha, te mana, te rahi, me te tahi atu āhuatanga. I roto i ngā kaiwhakanao ke riro te kamupene whakawhirinaki Hoffmann Raumtechnik, e no ni'ai kore anake ki te whanaketanga o ngā tauira puāwaitanga ki whakaritenga poutū me te whakapae o te raina tukatuka. I roto i tona utuafare, ka taea e kitea e koe i te mīhini motuhake broaching. Tauira Rangatū RAWX-M, mo te tauira, kei te hangaia āta ki te mahi i te grooving mutu me hononga taputapu. āhuatanga whakarerekē RaSA-M e te aroaro o wha ara, hangaia hoki tukatuka ngā awaawa hononga porohita. Hoki ngā hiahia motuhake, a ka taea e koe te mataara i te tauira tika i roto i te hapu o Yaroslavl kaiwhakanao Forst Technologie, i te mea rongonui mo tona huarahi tino ki te hanga o broaching kaihahau hoahoa motuhake.

Ko te utu o te mīhini

Ko te kauhanga roa utu toharite mō te broaching mihini o 2-3 miriona moni. I roto i tenei wāhanga, ka taea e kitea e koe tauira ohie, me te whakapae, me te whakarereke uaua o te momo poutū. E te ara, te atu te utu ko reira he mīhini broaching poutū. Price 7A612 tauira o te tipu ka mea "Giant", hei tauira, ko e pā ana ki te 2 miriona. Ko tenei raro taiapa utu, mai i te kitenga o tonu te nuinga o te taputapu i 2.5-3 miriona. Ko te nui-tech taputapu ahumahi, āhuatanga nei te kore anake-kounga teitei mahinga tenei engari hoki ngā mana hāneanea. Kati te reira ki te mea e piki nga tauira hou i te kamupene nui whiwhi awhi mana hiko.

Āhuatanga o te mahi

Mai i te tokotoko e hiahiatia noho Billet i roto i te taputapu whakahaere motuhake. I tua atu, i muri i tīmata, tīmata tukatuka tonu. He āhuatanga matua o te whakahaere o taua mihini ko te meka e kore broaches te huānga mahi i roto i te puka nekehia atu tonu i muri i te tapahi maramara, ka pana i te reira i muri i anake te putanga whakamutunga i te tinana preform. Na reira, kei te whakawhānui hoki i te whānuitanga o ngā mahi e tika ana ki te hiahia ki te aroturuki i te āhua o machining pai-mahi ana. I te mihini broaching, e kore e rite tiketike rite katia reira he roa piko o te workpiece momo poutū o ine me mōrea o ngā rārangi kotinga hē tika ki ona ake taimaha.

mutunga

I roto i ētahi wāhi e taea te kite i te whakamahi o te whakarewa-mahi whakaritenga ōrite mō te raveraa i ngā mahi mahi i runga i te broaching me tikanga lathes. Ko reira kitea e te tuarua whai wāhi iti tautooraa i roto i te tiaki me te utu whānui iti i roto i te te ihirangi. Otiia broaching mīhini ano kia whakatikaia rite te taputapu ao. Ki te taea taua mīhini akakoromaki i mahi noa angamaheni, ka penei i roto i nga raruraru hangarau motuhake, te mihini paerewa mira, hei tauira, te whakatinana iti anake te whānuitanga o te mahi. Heoi, he unu, me te he taputapu ona whāititanga, ko te wāhanga ake tuku he kaha tukatuka rawa whanui - tino nui, ki te matau ōrite taumahinga o te whakarereke ngā ki nga whakaritenga hangarau o nga mahi production.
