Magnetic vs Pneumatic Workholding for Shein Aluminium

Magnetic vs Pneumatic Workholding for Shein Aluminium

Umwanditsi: PFT, Shenzhen

Ibisobanuro

Gutunganya neza amabati yoroheje ya aluminium (<3mm) ahura nibibazo bikomeye byo gukora. Ubu bushakashatsi bugereranya sisitemu ya magnetiki na pneumatike ikomatanya mugihe cyo gusya kwa CNC. Ibipimo by'ibizamini birimo imbaraga zo gukomera, guhagarara neza (20 ° C - 80 ° C), guhindagurika kunyeganyega, no kugoreka hejuru. Pneumatic vacuum chucks yagumanye 0,02mm yuburinganire kumpapuro 0.8mm ariko bisaba gufunga neza. Electromagnetic chucks yatumaga 5-axis igera kandi igabanya igihe cyo gushiraho 60%, nyamara iterwa ningaruka za eddy zatumye ubushyuhe bwaho burenga 45 ° C kuri 15.000 RPM. Ibisubizo byerekana sisitemu ya vacuum itezimbere kurangiza kumpapuro> 0.5mm, mugihe ibisubizo bya magnetiki bitezimbere guhinduka kwa prototyping byihuse. Intambamyi zirimo uburyo bwa Hybrid butageragejwe hamwe nubundi buryo bufatika.

1 Intangiriro

Amabati mato ya aluminiyumu yinganda ziva mu kirere (uruhu rwa fuselage) kugeza kuri elegitoroniki (guhimba ubushyuhe). Nyamara ubushakashatsi bwakozwe mu nganda 2025 bugaragaza 42% by'inenge zuzuye zituruka ku gikorwa cyo gukora mu gihe cyo gutunganya. Ibikoresho bisanzwe bya mashini akenshi bigoreka impapuro zo munsi ya 1mm, mugihe uburyo bushingiye kuri kaseti butabura gukomera. Ubu bushakashatsi bugereranya ibisubizo bibiri byateye imbere: electromagnetic chucks ikoresha tekinoroji yo kugenzura remanence hamwe na sisitemu ya pneumatike hamwe no kugenzura ibyuka byinshi.

2 Uburyo

2.1 Igishushanyo mbonera

• Ibikoresho: 6061-T6 impapuro za aluminium (0.5mm / 0.8mm / 1.2mm)

• Ibikoresho:

  • Magnetic: GROB 4-axis electromagnetic chuck (0.8T ubukana bwumurima)

  • Umusonga: SCHUNK isahani ya vacuum hamwe na 36-zone ya manif

• Kwipimisha: Uburinganire bwubuso (laser interferometer), amashusho yumuriro (FLIR T540), isesengura ryinyeganyeza (3-axis yihuta)

2.2

1. Igihagararo gihamye: Gupima gutandukana munsi ya 5N imbaraga zuruhande

2. Amagare yubushyuhe: Andika ubushyuhe bwikigereranyo mugihe cyo gusya (Ø6mm urusyo, 12,000 RPM)

3. Dynamic Rigidity: Kugabanya vibration amplitude kuri resonant frequency (500–3000 Hz)

3 Ibisubizo n'isesengura

3.1

Igishushanyo 1: Sisitemu ya Vacuum yagumanye <5μm ihindagurika ryubuso mugihe cyo gusya mu maso, mugihe gufatira magneti kwerekanaga 0.12mm kuzamura impande zombi kubera kwaguka kwinshi.

3.2 Ibiranga kunyeganyega

Indwara ya pneumatike yahujwe na 15dB kuri 22200Hz - ingenzi kubikorwa byiza. Gukoresha magnetiki byerekanaga 40% hejuru ya amplitude kumurongo wibikoresho.

4 Ikiganiro

4.1 Ubucuruzi bw'ikoranabuhanga

• Ibyiza bya pneumatike: Ubushuhe buhebuje bwumuriro hamwe na vibration damping bikwiye kwihanganira ibintu byinshi nkibikoresho bya optique.

• Magnetic Edge: Kwihuta byihuse bifasha akazi-iduka ryibidukikije bikora ingano zitandukanye.

Imipaka: Ibizamini ukuyemo impapuro zisobekeranye cyangwa amavuta aho imikorere ya vacuum igabanuka> 70%. Hybrid ibisubizo byemeza ubushakashatsi buzaza.

5 Umwanzuro

Kumashini ya aluminiyumu yoroheje:

1. Gukora pneumatike bitanga ibisobanuro bihanitse kubyimbye> 0.5mm hamwe nubuso butabangamiwe

2. Sisitemu ya magnetique igabanya igihe cyo kugabanya 60% ariko bisaba ingamba zikonje zo gucunga ubushyuhe

3. Guhitamo neza biterwa nibisabwa bikenewe hamwe no kwihanganira ibisabwa

Ubushakashatsi bw'ejo hazaza bugomba gushakisha imiterere ya Hybrid clamps hamwe nubushakashatsi buke bwa electromagnet.
