Автоматическая машина для обвязки арматурной проволоки для пучков стержней и прутков.

Резюме The automatic rebar wire tying machine secures bar and rod bundles using continuous steel wire ties twisted at programmable spacing. Heavy rebar bundles advance along an automated powered roller conveyor, where heavy-duty tying heads clamp the circumference, feed and twist high-strength steel wire ties, and release the bundle for downstream handling or stacking. Engineered for integration with high-speed rolling mill finishing lines, the multi-head tying station handles both ribbed rebar and round rod bundles with consistent tensioning, automated wire feed, and mill-synchronized cycle rates.

How the tying cycle works

The automated bundle tying station sequences four integrated sub-cycles to ensure secure bar restraint without mill pacing bottlenecks. Multi-head configurations (such as 4 heads tying 4 wires simultaneously [manufacturer rating]) allow concurrent operations along the load length:

Station Sequence Mechanical Process & Automation Cycle
Индексирование потока Rebar or merchant rod bundles transfer onto the motorized roller conveyor and index to the primary tying datum against mechanical alignment guides.
Head Closure Heavy-duty tying arms pivot and close circumferentially around the bar bundle profile, forming an enclosed wire guide channel.
Wire Twist & Shear High-torque twisting mechanisms draw steel tying wire through the guides, tension the loop securely around the perimeter, twist the joint, and cleanly shear the knot.
Outfeed Transfer The tying heads disengage and retract to standby position; the tied bundle indexes forward for final inspection, overhead craning, or automated master stacking.
Multi-profile Run The tying head assembly adjusts via servo or pneumatic positioning to accommodate round bar, hex bar, or deformed rebar cross-sections without manual tool changes.

Почему именно стальные проволочные стяжки?

  • Сильный. High-tensile steel wire holds heavy bar bundles securely during overhead crane lifting, rough rail shunting, and ocean transport without joint slippage.
  • Часто встречается на мельницах. Steel wire ties are the metallurgical industry standard, fully compatible with downstream rebar processing, outdoor storage yards, and automated unbinding equipment.
  • Бюджетный. Continuous coiled steel wire costs significantly less per completed tie than heat-treated high-tensile steel strapping or heavy steel bands.
  • Равномерное расстояние. Multi-head tying stations place wire knots at precise, pre-programmed intervals across the entire bundle span, preventing mid-span belly sag.
  • Controlled material properties. The tying head utilizes unalloyed, annealed low-carbon steel wire rod [manufacturer rating] with a tensile strength of 380–450 MPa and an elongation of 28–32% [manufacturer rating], typically operating with standard wire diameters from Ø6.3 mm to Ø8.0 mm [manufacturer rating] to yield pliable, split-free twist knots.

Количество галстуков в связке

The required number of wire ties per bundle depends on bundle span, total metric tonnage, handling method, and bar flexural rigidity.

Пример решения задачи (иллюстративный).

Параметр Значение
Длина пучка (иллюстративная) 12,000 мм
Расстояние между галстуками (иллюстративное) 2,000 мм
Количество галстуков в связке: 12 000 ÷ 2 000 + 1 7
Количество пакетов в час (иллюстративный показатель) 40
Количество галстуков в час, 7 × 40 280

Note: For specialized continuous bundle lines, cycle speeds can achieve 30–40 s per binding cycle, enabling line outputs of up to 60 units per hour [manufacturer rating] under optimal infeed conditions.

Что мы устанавливаем для каждого комплекта

Operating parameters are configured via the HMI terminal based on production schedule criteria:

настройка Операционная зависимость Техническая спецификация
Глав Длина пучка и завязки Active tying heads engaged along the beam (e.g., 4-head synchronized operation [manufacturer rating])
Провод Диаметр на единицу веса связки Wire gauge selection (Ø6.3–8.0 mm low-carbon wire [manufacturer rating]) matched to package mass
Поворот Количество оборотов на одну ничью Controlled rotation angle and twist clamp force to achieve optimal knot shear resistance
Конвейер Темп мельницы VFD roller conveyor acceleration and indexing matched to continuous finishing mill cycle times

Контрольный список выбора

  • Диаметр и длина стержня.
  • Вес и диаметр пучка.
  • Галстуки в связке.
  • Диаметр проволоки.
  • Количество пакетов в час.
  • Схема расположения линий.

Безопасность

  • Keep clear of tying heads while they close and tension high-tensile wire.
  • Lock out and tag out (LOTO) electrical, hydraulic, and pneumatic lines before clearing wire feed jams or replacing wire coils.
  • Wear cut-resistant heavy industrial gloves and full-face eye protection when clearing cut wire ends or handling coiled stock.
  • For CE markets, the machine is designed, built, and certified to ISO 12100:2010 (Risk assessment and risk reduction) and EN 415-10:2014 (Safety requirements for strapping and tying machines).

Часто задаваемые вопросы по инженерным вопросам

В: Что делает эта машина? A: It automatically compresses, binds, and ties steel rebar and industrial rod bundles using twisted industrial steel wire ties at programmable center-to-center distances.

Q: Why wire and not strap? A: Steel wire provides high clamping resilience for heavy, irregular steel bundles at a substantially lower consumable cost per tie compared to punched or notched steel strapping.

Q: How many ties per bundle? A: Tie counts depend strictly on bundle overall length, payload mass, and customer logistics criteria; a representative 12,000 mm bundle with 2,000 mm spacing requires 7 ties per bundle, as shown in the worked calculation.

Q: Can it tie smooth round rods as well as deformed rebar? A: Yes. The tying head perimeter guide adjusts its clamping aperture and wire twist parameters to bind smooth rod bundles, merchant bars, and deformed rebar bundles with equal gripping integrity.

Q: Does it keep up with the mill? A: Yes. Conveyor drive speeds, head indexing, and multi-wire simultaneous cycles (achieving cycle paces of 30–40 s per cycle [manufacturer rating]) are synchronized directly with mill cooling bed release rates.

Q: What wire specifications are compatible with the tying mechanism? A: The system standardly runs unalloyed, annealed low-carbon steel wire rod within Ø6.3–8.0 mm diameters, featuring 380–450 MPa tensile strength and 28–32% elongation [manufacturer rating].

В: Какие стандарты применяются? A: For CE-regulated markets, equipment engineering complies with ISO 12100:2010 and EN 415-10:2014 machinery safety directives.
