Iimpazamo ezinkulu ezilithoba kumatshini, zingaphi ozaziyo?

Impazamo yoMatshini ibhekisa kwiqondo lokutenxa phakathi kweeparamitha zejometri (ubungakanani bejometri, imilo yejometri kunye nesikhundla sokubambisana) yecandelo emva komatshini kunye neeparitha ezifanelekileyo zejometri.

Iqondo lesivumelwano phakathi kweeparameters zejometri zangempela kunye neeparitha ezifanelekileyo zejometri emva kokuba inxalenye yomatshini kukuchaneka komatshini. Incinci impazamo yomatshini, kokukhona inqanaba lokuhambelana liphezulu kwaye liphezulu ukuchaneka komatshini.7075 aluminium machining

Ukuchaneka komatshini kunye nempazamo yomatshini ziindlela ezimbini zengxaki. Ngoko ke, ubungakanani bempazamo yomatshini bubonisa inqanaba lokuchaneka komatshini. Izizathu eziphambili zeempazamo zomatshini zezi zilandelayo:

1. Impazamo yokwenziwa kwesixhobo somatshini

Impazamo yokwenziwa kwesixhobo somatshini ikakhulu ibandakanya impazamo yokujikeleziswa kwe-spindle, impazamo yesikhokhelo sikaloliwe kunye nempazamo yesixokelelwano sothumelo.

Impazamo yokujikeleza kwe-Spindle ibhekiselele kuguquko lweyona ndawo ijikelezayo i-axis ye-spindle ngokunxulumene ne-avareji yomjikelezo we-axis ngephanyazo ngalinye, eliya kuchaphazela ngokuthe ngqo ukuchaneka komsebenzi oza kuqhutyelwa phambili. Ezona zizathu ziphambili zempazamo yokujikeleza kokusonta yimpazamo ye-coaxiality ye-spindle, impazamo yokuthwala ngokwayo, impazamo ye-coaxiality phakathi kweebheringi, kunye nokujikeleza kwe-spindle. Isikhokelo sikaloliwe luphawu lokumisela unxulumano lwendawo yecandelo ngalinye lesixhobo somatshini kwisixhobo somatshini, kwaye ikwaluphawu lwentshukumo yesixhobo somatshini.aluminiyam cnc machining

Impazamo yokwenziwa komgaqo kaloliwe ngokwawo, ukuguga okungalinganiyo kwesikhokelo sikaloliwe kunye nomgangatho wofakelo zizinto ezibalulekileyo ezibangela impazamo yesikhokhelo sikaloliwe. Impazamo yesixokelelwano sothumelo ibhekisa kwimpazamo yentshukumo ehambelanayo phakathi kwezinto zothumelo ekuqaleni nasekupheleni kwekhonkco lothumelo. Ibangelwa yimpazamo yokuvelisa kunye nendibano yecandelo ngalinye kwikhonkco lokuhambisa, kunye nokunxiba ngexesha lokusetyenziswa.

2. Impazamo yejometri yesixhobo

Nasiphi na isixhobo siya kunxiba ngokuqinisekileyo ngexesha lokusika, okuya kubangela utshintsho kubukhulu kunye nokuma kwendawo yokusebenza. Impembelelo yempazamo yejiyometri yesixhobo kwimpazamo yomatshini iyahluka ngohlobo lwesixhobo: xa isixhobo sobungakanani obusisigxina sisetyenziselwa umatshini, impazamo yokwenziwa kwesixhobo iya kuchaphazela ngokuthe ngqo ukuchaneka komatshini womsebenzi; kwizixhobo eziqhelekileyo (ezifana nezixhobo zokuguqula, njl.), Iphutha layo lokuvelisa Ayinampembelelo ngqo kwiimpazamo zomatshini.

3. Impazamo yejiyometri yesixhobo

Umsebenzi we-fixture kukwenza i-workpiece ilingane nesixhobo kunye nesixhobo somatshini ukuba sibe nesigxina esichanekileyo, ngoko ke impazamo yejometri ye-fixture inempembelelo enkulu kwimpazamo yomatshini (ingakumbi impazamo yesimo).

4. Impazamo yokubeka

Impazamo yokubeka ubukhulu becala ibandakanya impazamo yereferensi yokulungelelaniswa kakuhle kunye nempazamo engalunganga yokwenziwa kwesixhobo sokumisa isibini. Xa ucubungula i-workpiece kwisixhobo somatshini, izinto ezininzi zejometri kwi-workpiece kufuneka zikhethwe njengedatum yokubeka ngexesha lokucubungula. datum) ayingqamani, impazamo yolungelelwaniso lwedatum iya kwenzeka.

Indawo yokubeka iworkpiece kunye nefixture positioning element kunye zenza iperi yokumisa. Olona tshintsho luphezulu lwendawo yokusebenza olubangelwa kukwenziwa ngendlela engachanekanga yeperi yokumisa kunye nomsantsa wokumatanisa phakathi kwezibini zokumisa ubizwa ngokuba yimpazamo yokwenziwa kwempazamo yokumisa iperi. Iphutha lokuvelisa elingalunganga lesibini sokumisa liya kwenzeka kuphela xa indlela yokulungelelanisa isetyenziselwa ukucubungula, kwaye ayiyi kwenzeka kwindlela yokusika isilingo.

5. Imposiso ebangelwa kukuguqulwa kwamandla enkqubo yenkqubo

Ubunzima bomsebenzi womsebenzi: Ukuba i-workpiece yokuqina kwinkqubo yenkqubo iphantsi kakhulu xa kuthelekiswa nezixhobo zoomatshini, izixhobo, kunye nezixhobo, phantsi kwesenzo sokusika amandla, ukuguqulwa komsebenzi ngenxa yokungabikho ngokwaneleyo kuya kuba nefuthe elikhulu kwiimpazamo zomatshini.

Ukuqina kwesixhobo: Ukuqina kwesixhobo sokuguqula i-cylindrical kwindlela eqhelekileyo (y) yobuso bomatshini bukhulu kakhulu, kwaye i-deformation yayo inokungahoywa. Xa unesithukuthezi umngxuma wangaphakathi kunye nobubanzi obuncinci, ukuqina kwebar yesixhobo kubi kakhulu, kwaye ukuguqulwa kwamandla kwebha yesixhobo kunempembelelo enkulu ekuchanekeni komatshini womngxuma.

Ukuqina kwezixhobo zesixhobo somatshini: Izixhobo zesixhobo somatshini zenziwe ngamacandelo amaninzi. Akukho ndlela yokubala ilula ifanelekileyo yokuqina kwezixhobo zesixhobo somatshini. Okwangoku, ukuqina kwamacandelo esixhobo somatshini kunqunywe ngokukodwa ngeendlela zokulinga. Izinto ezichaphazela ukuqina kwamacandelo esixhobo somatshini zibandakanya impembelelo yokunxibelelana kobuso bomda odibeneyo, impembelelo yokungqubana, ifuthe leenxalenye eziphantsi, kunye nefuthe lokucoca.iinxalenye ze-aluminium cnc machining

6. Iimpazamo ezibangelwa yi-thermal deformation yenkqubo yenkqubo

I-thermal deformation yenkqubo yenkqubo inempembelelo enkulu kwimpazamo yomatshini, ngokukodwa kwi-machining echanekileyo kunye ne-machining enkulu, i-machining impazamo ebangelwa yi-thermal deformation ngamanye amaxesha i-akhawunti ye-50% yephutha le-workpiece lilonke.

7. Impazamo yohlengahlengiso

Kwinkqubo nganye yomatshini, kuhlala kukho indlela enye okanye enye uhlengahlengiso kwinkqubo yenkqubo. Ekubeni uhlengahlengiso alunakuchaneka ngokupheleleyo, kwenzeka impazamo yohlengahlengiso. Kwinkqubo yenkqubo, ukuchaneka kwe-positional ye-mutual ye-workpiece kunye nesixhobo kwisixhobo somatshini siqinisekiswa ngokulungelelanisa isixhobo somatshini, isixhobo, isilungiso okanye i-workpiece. Xa ukuchaneka kwasekuqaleni kwezixhobo zoomatshini, izixhobo, izixhobo kunye neendawo zokusebenza ezingenanto zonke zihlangabezana neemfuno zobuchwepheshe ngaphandle kokuqwalasela izinto eziguquguqukayo, impazamo yokulungelelanisa idlala indima ebalulekileyo kwimpazamo yomatshini.

8. Impazamo yomlinganiselo

Xa inxalenye ilinganiswa ngexesha okanye emva kokucutshungulwa, ukuchaneka kokulinganisa kuchaphazeleka ngokuthe ngqo kwindlela yokulinganisa, ukuchaneka kwesixhobo sokulinganisa, kunye ne-workpiece kunye nezinto ezizimeleyo kunye nenjongo.

9. Uxinzelelo lwangaphakathi

Uxinzelelo olukhoyo ngaphakathi kwenxalenye ngaphandle kwamandla angaphandle lubizwa ngokuba luxinzelelo lwangaphakathi. Emva kokuba uxinzelelo lwangaphakathi lwenziwe kwi-workpiece, i-workpiece metal iya kuba kwindawo engazinzanga yezinga eliphezulu lamandla. Iza kuguqula ngokuzenzekelayo ukuya kwinqanaba elizinzile lezinga eliphantsi lamandla, lihamba kunye ne-deformation, ukwenzela ukuba i-workpiece ilahlekelwe ukuchaneka kwayo kwasekuqaleni.
