The Deep Hole Boring Tube ndiye gawo lalikulu la BTA (Boring and Trepanning Association) makina obowola mabowo akuya. Amapangidwa kuti azipanga bwino kwambiri mabowo akuya okhala ndi chiŵerengero chakuya mpaka m'mimba mwake (D: d) ≥ 10: 1, amagwiritsidwa ntchito kwambiri m'mafakitale oyendetsa ndege, mphamvu, ndi magalimoto. Imagwirizana ndi Single Tube (STS) ndi Double Tube (DTS/Ejector), pogwiritsa ntchito makina oziziritsa kupanikizika kwambiri komanso okhazikika kuti zitsimikizire kutuluka kokhazikika kwa chip.
Core Positioning & Working Principle
- Essence: Kapangidwe kakang'ono ka tubular komwe kamagwira ntchito ndi mitu yapadera yoboola / yoboola kuti itumize mphamvu zodulira, kupereka zoziziritsa kukhosi, ndikutulutsa tchipisi.
- Single chubu (STS/BTA): Woziziritsa amalowa m'dera lodulira kudzera pa annulus pakati pa chubu OD ndi khoma la dzenje; tchipisi amatulutsidwa kudzera mu chubu chamkati cha chubu. Pamafunika workpiece kusindikiza ndi kuthamanga mutu. Abwino kwa dzenje diameters 12-850 mm ndi kuya ≥ 100:1. Kuchita bwino ndi nthawi 3-5 kuposa kubowola mfuti.
- Double Tube (DTS/Ejector): Zoziziritsa kuziziritsa zimayenda mu annulus pakati pa machubu amkati ndi akunja; tchipisi amasamutsidwa kudzera mu chubu chamkati. Palibe mutu wopanikizika womwe umafunikira, ndikupangitsa kuti ikhale yogwirizana ndi zida wamba zamakina. Kuzama kwakukulu kovomerezeka ndi 1000 mm (mpaka 2000 mm okhala ndi ma adapter apadera), oyenera ma diameter a dzenje 18-250 mm.
Kapangidwe Kofunikira & Zida
| Chigawo | Ntchito | Zodziwika bwino |
| Thupi Thupi | Imatumiza torque, imatulutsa zoziziritsa kukhosi, imachotsa tchipisi | OD: 16–300 mm, Makulidwe a Khoma: 3–20 mm, Utali: 1–6 m |
| Kugwirizana Ulusi | Imalumikizana ndi mutu wotopetsa / chothandizira | Ulusi umodzi/zoyambira zambiri (monga 4ST/1ST), Class 6g yolondola, yogwirizana ndi miyezo ya ISCAR/UNISIG |
| Mapepala Otsogolera | Imatsimikizira kuwongoka ndi kutha kwa pamwamba | Kuyika kwa Tungsten carbide, M'lifupi: 5-15 mm, Kuchotsa ndi dzenje: 0.01-0.03 mm |
| Zakuthupi | Imatsimikizira kukhazikika komanso kukana kuvala | Aloyi Zitsulo (4140/4340), Nitrided/Chrome-yokutidwa pamwamba, Kulimba: HRC 30–45 |
Zida Zaukadaulo (General Reference)
| Gulu la Parameter | Single chubu (STS) | Double Tube (Ejector) | Ndemanga |
| Oyenerera Hole Diameter | 12-850 mm | 18-250 mm | Makampani wamba |
| Kuzama kovomerezeka | ≤ 200:1 | ≤ 100:1 | Sinthani kutengera kukhazikika kwa makina & makina ozizira |
| Kupanikizika Kozizira | 5-20 MPa | 3-10 MPa | Imawonetsetsa kuyimitsidwa kwa chip pakusamuka |
| Mlingo Wozizira Wozizira | 50-800 L / mphindi | 30-500 L / mphindi | Kuwonjezeka ndi dzenje awiri ndi kuya |
| Kuwongoka kwa Tube | ≤ 0.02 mm/m | ≤ 0.03 mm/m | Zofunikira pakuwongoka kwa dzenje ndi cylindricity |
| Kukalipa Pamwamba | ID Ra ≤ 1.6 μm | ID Ra ≤ 3.2 μm | Amachepetsa chiopsezo cha chip clogging |
| Kulondola Kolumikizana | Kuthamanga kwa Ulusi ≤ 0.01 mm | Mofanana ndi Kumanzere | Imawonetsetsa kuti concentricity ndi dynamic balance |
Mawonekedwe a Ntchito & Maupangiri Osankha
- Zida Zoyenera: Mpweya wa carbon, aloyi chitsulo, chitsulo chosapanga dzimbiri, titaniyamu aloyi, high-temperature alloys. Zothandiza makamaka pazinthu zomwe zimapanga tchipisi zazitali, zazingwe.
- Zosankha Zosankhira:
- Diameter/Kuzama: Pamabowo <18 mm, ikani patsogolo Single Tube. Pakuya> 1000 mm, ikani patsogolo Single Tube + Pressure Head.
- Mtundu wa Makina: Gwiritsani Ntchito Tube Pawiri pazigawo zokhazikika zopangira ma lathes / ofukula; gwiritsani ntchito Single Tube pamakina odzipatulira a dzenje lakuya.
- Kuchita bwino: Single Tube imapereka magwiridwe antchito apamwamba; Double Tube imapereka kusinthasintha kwakukulu.
Ubwino & Zolemba Zogwirira Ntchito
- Ubwino Wachikulu: Kuthekera kwakukulu kwakuya mpaka m'mimba mwake, kulondola kwambiri kwa makina (Hole Tolerance IT7-IT9, Surface Ra ≤ 1.6 μm), kutulutsa kosalala kwa chip, komanso kusinthasintha kwazinthu zambiri.
- Mfundo Zogwirira Ntchito:
- Kusefedwa kozizira kozizira kuyenera kukhala ≤ 10 μm kuteteza kutsekeka.
- Bowo loyendetsa likufunika (Diameter = Boring Tube ID - 0.5 mm, Utali ≥ 2x dzenje m'mimba mwake).
- Kuwongolera kudula magawo: Kuthamanga v = 30-100 m / min, Dyetsani f = 0.1-0.3 mm / rev (kusintha malinga ndi zinthu).
Chitsanzo Chodziwika bwino (UNISIG Standard)
| Bowo Loyenera Diameter (mm) | Boring chubu OD (mm) | Boring Tube ID (mm) | Utali wovomerezeka (m) |
| 20–30 | 19.05 | 15.00 | 1.5 |
| 31–40 | 28.58 | 22.00 | 2.0 |
