Ṣiṣeto pipe ti aluminiomu dì tinrin (<3mm) dojukọ awọn italaya iṣẹ ṣiṣe pataki. Iwadi yii ṣe afiwe oofa ati awọn eto didi pneumatic labẹ awọn ipo milling CNC ti iṣakoso. Awọn paramita idanwo pẹlu aitasera agbara didi, iduroṣinṣin igbona (20°C–80°C), riru gbigbọn, ati ipadaru dada. Pneumatic igbale chucks bojuto 0.02mm flatness fun 0.8mm sheets sugbon beere mule lilẹ roboto. Awọn chucks itanna ṣiṣẹ iwọle 5-axis ati akoko iṣeto ti o dinku nipasẹ 60%, sibẹsibẹ awọn ṣiṣan eddy ti o fa alapapo agbegbe ti o kọja 45°C ni 15,000 RPM. Awọn abajade tọkasi awọn eto igbale jẹ ki ipari dada jẹ> 0.5mm, lakoko ti awọn solusan oofa ṣe imudara irọrun fun iṣelọpọ iyara. Awọn idiwọn pẹlu awọn isunmọ arabara ti ko ni idanwo ati awọn omiiran ti o da lori alemora.

1 Ọrọ Iṣaaju

Tinrin aluminiomu sheets agbara awọn ile-iṣẹ lati Aerospace (fuselage awọn awọ ara) to Electronics (ooru ifọwọ ifọwọ). Sibẹsibẹ awọn iwadii ile-iṣẹ 2025 ṣafihan 42% ti awọn abawọn deede wa lati iṣipopada iṣẹ-ṣiṣe lakoko ẹrọ. Mora darí clamps nigbagbogbo daru iha-1mm sheets, nigba ti teepu-orisun ọna ko rigidity. Iwadi yii ṣe iwọn awọn ipinnu ilọsiwaju meji: awọn chucks elekitirogi leveraging imọ-ẹrọ iṣakoso isọdọtun ati awọn eto pneumatic pẹlu iṣakoso igbale agbegbe pupọ.

2 Ilana

2.1 esiperimenta Design

• Awọn ohun elo: 6061-T6 aluminiomu sheets (0.5mm/0.8mm/1.2mm)

• Ohun elo:

  • Oofa: GROB 4-axis chuck itanna (kikan aaye 0.8T)

  • Pneumatic: SCHUNK igbale awo pẹlu 36-ibi ọpọlọpọ

• Idanwo: Filati oju (lesa interferometer), aworan igbona (FLIR T540), itupalẹ gbigbọn (awọn accelerometers-axis 3)

2.2 Igbeyewo Ilana

1. Iduroṣinṣin Aimi: Diwọn ipalọlọ labẹ agbara ita 5N

2. Gigun kẹkẹ gbigbona: Gbigbasilẹ awọn gradients iwọn otutu lakoko milling (Ø6mm ọlọ ipari, 12,000 RPM)

3. Rigidity Yiyi: Ṣe iwọn titobi gbigbọn ni awọn igbohunsafẹfẹ resonant (500–3000 Hz)

3 Esi ati Analysis

3.1 Clamping Performance

Nọmba 1: Awọn ọna ṣiṣe igbale ṣe itọju <5μm iyatọ dada lakoko milling oju, lakoko ti o jẹ wiwọ oofa fihan igbega eti 0.12mm nitori imugboroosi gbona.

3.2 Awọn abuda gbigbọn

Pneumatic chucks attenuated harmonics nipasẹ 15dB ni 2,200Hz – lominu ni fun itanran-ipari awọn iṣẹ. Idaduro iṣẹ oofa ṣe afihan iwọn 40% ti o ga julọ ni awọn loorekoore ilowosi irinṣẹ.

4 Ifọrọwọrọ

4.1 Technology Tradeoffs

• Anfani Pneumatic: iduroṣinṣin igbona ti o ga julọ ati didimu gbigbọn ba awọn ohun elo ifarada giga bii awọn ipilẹ paati opiti.

• Edge oofa: Atunto ni iyara ṣe atilẹyin awọn agbegbe ile itaja iṣẹ ti n mu awọn iwọn ipele oniruuru.

Idiwọn: Awọn idanwo ti a yọkuro perforated tabi awọn iwe ororo nibiti iṣẹ ṣiṣe igbale lọ silẹ> 70%. Awọn ojutu arabara ṣe atilẹyin ikẹkọ iwaju.

5 Ipari

Fun ẹrọ dì aluminiomu tinrin:

1. Iṣeduro iṣẹ pneumatic n pese pipe ti o ga julọ fun awọn sisanra> 0.5mm pẹlu awọn ipele ti ko ni adehun

2. Awọn eto oofa dinku akoko ti kii-gige nipasẹ 60% ṣugbọn nilo awọn ilana itutu fun iṣakoso igbona

3. Aṣayan ti o dara julọ da lori awọn iwulo igbejade dipo awọn ibeere ifarada

Iwadi ojo iwaju yẹ ki o ṣawari awọn clamps arabara adaṣe ati awọn apẹrẹ elekitirogi-kikọlu kekere.
