斷橋鋁型材復合機是建筑門窗行業中用于制造高性能隔熱型材的核心設備，其核心功能是將鋁合金型材與隔熱條通過機械壓力緊密結合，形成具有斷橋結構的復合型材。這種設備通過創新的技術設計，解決了傳統鋁合金型材導熱性強的問題，使門窗兼具高強度與優異的隔熱性能，成為現代建筑節能的關鍵技術支撐。

The broken bridge aluminum profile composite machine is a core equipment used in the construction door and window industry to manufacture high-performance insulation profiles. Its core function is to tightly combine aluminum alloy profiles with insulation strips through mechanical pressure, forming composite profiles with broken bridge structures. This device solves the problem of strong thermal conductivity of traditional aluminum alloy profiles through innovative technological design, making doors and windows have both high strength and excellent thermal insulation performance, becoming a key technical support for modern building energy conservation.

一、核心功能：構建隔熱斷橋結構

1、 Core function: Building a thermal insulation bridge structure

隔熱條與鋁材的機械復合

Mechanical composite of insulation strip and aluminum material

復合機通過三組硬質滾壓輪（每組包含上下兩個滾輪）對已穿入隔熱條的鋁合金型材施加壓力，使鋁材與隔熱條形成 “咬合式” 連接。例如，在穿條式工藝中，隔熱條（通常為 PA66GF25 尼龍材料）被預先穿入鋁材的齒形槽內，復合機通過滾壓輪的壓力將鋁材與隔熱條擠壓成一個整體，形成 “斷橋” 結構，阻斷熱量傳導路徑。這種連接方式的抗剪強度可達 30MPa 以上，確保型材在長期使用中不會出現分離現象。

The composite machine applies pressure to the aluminum alloy profile that has been penetrated into the insulation strip through three sets of hard rolling wheels (each set containing two upper and lower rollers), forming a "bite type" connection between the aluminum material and the insulation strip. For example, in the strip through process, the insulation strip (usually made of PA66GF25 nylon material) is pre inserted into the tooth shaped groove of the aluminum material. The composite machine squeezes the aluminum and insulation strip into a whole through the pressure of the rolling wheel, forming a "broken bridge" structure to block the heat conduction path. The shear strength of this connection method can reach over 30MPa, ensuring that the profiles will not separate during long-term use.

多維度壓力控制

Multidimensional pressure control

設備配備多組壓力傳感器和數控系統，可實時監測并調整滾壓力度。例如，針對不同厚度的隔熱條（12-80mm），系統會自動計算所需壓力值，并通過精密絲桿和直線導軌調整滾壓輪間距，確保壓力均勻分布。這種精確控制避免了傳統人工操作中因壓力不均導致的型材變形或連接不牢問題。

The equipment is equipped with multiple sets of pressure sensors and a numerical control system, which can monitor and adjust the rolling pressure in real time. For example, for insulation strips of different thicknesses (12-80mm), the system will automatically calculate the required pressure value and adjust the spacing between the rolling wheels through precision screws and linear guides to ensure even pressure distribution. This precise control avoids the deformation of profiles or weak connections caused by uneven pressure in traditional manual operations.

二、技術創新：智能化與高效生產

2、 Technological Innovation: Intelligence and Efficient Production

數控自動化設計

Numerical Control Automation Design

現代復合機普遍采用雙軸或五軸數控系統，支持參數化編程。用戶只需在觸摸屏輸入型材規格（如寬度、高度、隔熱條類型），設備即可自動調用預設參數，完成刀盤高度、滾壓輪間距等調整。例如，更換一種新的型材型號時，傳統設備需人工耗時 30 分鐘調整，而數控復合機可在 3 分鐘內完成自動切換，生產效率提升 80% 以上。

Modern composite machines commonly use dual axis or five axis CNC systems, supporting parametric programming. Users only need to input the profile specifications (such as width, height, and insulation strip type) on the touch screen, and the device will automatically call the preset parameters to adjust the cutter height, rolling wheel spacing, and other parameters. For example, when replacing a new profile model, traditional equipment requires 30 minutes of manual adjustment, while CNC composite machines can automatically switch within 3 minutes, increasing production efficiency by more than 80%.

多動力協同驅動

Multi power collaborative drive

高端設備采用六驅系統（每組滾壓輪獨立驅動），確保型材在擠壓過程中受力均衡。例如，在處理寬度達 300mm 的大型型材時，六組滾壓輪同步施加壓力，避免因局部受力不均導致的型材彎曲或扭曲。這種設計使型材的直線度誤差控制在 ±0.5mm/m 以內，遠超行業標準。

The high-end equipment adopts a six wheel drive system (each set of rolling wheels is independently driven) to ensure balanced force distribution during the extrusion process of the profile. For example, when processing large profiles with a width of up to 300mm, six sets of rolling wheels apply pressure synchronously to avoid bending or twisting of the profile due to uneven local stress. This design keeps the straightness error of the profile within ± 0.5mm/m, far exceeding industry standards.

三、應用場景：多樣化型材加工

3、 Application scenario: Diversified profile processing

建筑門窗與幕墻

Building doors, windows, and curtain walls

復合機生產的隔熱型材廣泛應用于節能門窗、幕墻系統。例如，在寒冷地區，采用復合機加工的斷橋鋁門窗可使室內外溫差達到 30℃以上，顯著降低供暖能耗；在高溫地區，則能有效阻隔太陽輻射熱，減少空調負荷。據測試，使用斷橋鋁門窗的建筑比普通鋁合金門窗節能 40%-50%。

The insulation profiles produced by composite machines are widely used in energy-saving doors, windows, and curtain wall systems. For example, in cold regions, using composite machined broken bridge aluminum doors and windows can achieve a temperature difference of over 30 ℃ between indoors and outdoors, significantly reducing heating energy consumption; In high-temperature areas, it can effectively block solar radiation heat and reduce air conditioning load. According to tests, buildings using broken bridge aluminum doors and windows are 40% -50% more energy-efficient than ordinary aluminum alloy doors and windows.

工業與交通領域

Industrial and transportation sectors

除建筑外，復合機還用于制造冷藏車箱體、高速列車車窗等對隔熱要求高的場景。例如，冷藏車箱體采用斷橋鋁型材后，可將保溫層厚度減少 30%，同時提升結構強度，延長使用壽命。

In addition to construction, composite machines are also used to manufacture refrigerated truck casings, high-speed train windows, and other scenarios that require high insulation. For example, when the refrigerated truck body is made of bridge cut aluminum profiles, the thickness of the insulation layer can be reduced by 30%, while improving the structural strength and extending the service life.
