Automatic Aluminum Window Bending Machine

The machine realizes a "one-click bending" workflow, minimizing manual intervention and cutting production time:

Auto Profile Positioning: High-precision photoelectric sensors and servo-driven pushers automatically align the aluminum profile with the bending mold, with a positioning error of ≤0.2mm. No manual marking or adjustment is needed, saving 3 - 5 minutes per piece compared to semi-automatic machines.

Auto Program Execution: After selecting a pre-stored program (e.g., "600mm×800mm window frame"), the machine automatically calculates the bending angle, clamping force, and speed. For batch production of 100+ identical window frames, it can complete processing in 1.5 - 2 hours (vs. 4 - 5 hours for manual bending).

Continuous Processing: The roller table conveyor connects to upstream profile cutting machines and downstream assembly lines, forming a continuous production loop. This reduces material handling time and increases the overall line capacity by 200% - 300%.

In practical applications, the machine can process 80 - 120 aluminum window profiles per 8-hour shift, far exceeding the 30 - 40 pieces completed by skilled manual workers.

Precision is critical for aluminum window production-even tiny angle deviations can cause poor frame assembly or air leakage. This machine solves this pain point through multiple precision control designs:

CNC Intelligent Angle Correction: The CNC system uses a high-precision angle encoder to real-time monitor the bending process. If the actual angle deviates from the set value (e.g., due to profile hardness differences), it automatically adjusts the hydraulic/pneumatic pressure to correct the angle, ensuring a final precision of ±0.5°.

Adaptive Clamping Force: The servo-controlled clamp adjusts its force based on the profile thickness and material hardness (e.g., 5kN for 1.2mm thin profiles, 25kN for 5mm thick profiles). This avoids two common issues: insufficient clamping (profile slips during bending) and excessive clamping (profile deformation).

Uniform Stress Distribution: The bending mold adopts a curved contact surface design, which distributes the bending force evenly across the profile surface. This prevents local indentations or cracks-common defects in manual bending-and ensures the profile retains its structural strength (tensile strength loss ≤5%).

Windows assembled with profiles bent by this machine have a frame fitting gap of ≤0.3mm, meeting the national "high-end aluminum window" quality standard and reducing rework rates from 12% (manual) to ≤1%.

Aluminum window designs vary widely (standard, arched, bay windows), and this machine's flexibility makes it suitable for multi-scenario production:

Multi-Profile & Multi-Angle Compatibility: It can bend all common aluminum window profiles (T-shaped, U-shaped, rectangular) and support custom angles (e.g., 135° for bay window corners, 180° for folded edges). The bending radius is adjustable from 50mm to 800mm, covering most decorative and structural needs.

Quick Mold Change: The mold uses a bolt-free locking structure-operators can replace molds (e.g., from "rectangular frame mold" to "arched mold") in 10 - 15 minutes, without professional tools. This is ideal for small-batch, multi-variety production (e.g., custom windows for villas).

Thin & Thick Profile Dual Adaptation: With adjustable bending force (50kN - 150kN) and clamp pressure, it can handle both thin decorative profiles (1.2mm - 2mm, common in residential windows) and thick load-bearing profiles (3mm - 5mm, used in high-rise building windows). No need to purchase separate machines for different profile types.

User-Friendly Interface: The 10.1-inch touchscreen supports Chinese/English/German (customizable) and displays real-time data (bending angle, pressure, remaining program count). It also provides visual operation guides-even new operators can master basic functions in 1 hour. For complex profiles, the system has a "simulation bending" function to preview the result before actual processing, avoiding material waste.

Comprehensive Safety Protection: The machine is equipped with multiple safety devices:

Emergency stop buttons (front and side) to halt operation immediately in case of anomalies;

Light curtain sensors around the working area-if hands or objects enter, the machine pauses automatically;

Overload protection for the hydraulic/pneumatic system-prevents damage to components from excessive pressure.

Easy Maintenance: Key components (hydraulic pump, servo motor) have a modular design for quick disassembly. The touchscreen displays maintenance reminders (e.g., "replace hydraulic oil after 500 hours") and fault diagnosis (e.g., "clamp sensor error-check wiring"), reducing downtime by 70% compared to traditional machines.
