3D Technological Innovation and Furniture Adaptation Advantages
-
Specialized Design for Large-Diameter Wires
- Enhanced Servo Power: A 4.5kW feeding servo paired with a planetary gear reducer delivers a torque output of 28N·m, ensuring non-slip feeding for 12mm iron wires at high speeds. Feeding stability is improved by 60% compared to traditional equipment.
- Upgraded Wear-Resistant Dies: Bending dies made of Cr12MoV quenched steel (hardness HRC58-62) can withstand 4,000 cycles of data usage. For 90° bends in 6-12mm wires, a three-stage progressive bending process (pre-bend 20° → mid-bend 50° → form 90°) prevents material stress cracking, ensuring a load-bearing capacity ≥500kg for the supports.
-
Four-Axis Linkage Precision Control
- The YAKI servo system features a position loop gain of 2,000rad/s. A 2.3kW bending servo drives the outer die for 360° rotation, working in tandem with the up-down movement of the inner die to achieve one-time forming of complex structures such as L-shaped, U-shaped, and T-shaped furniture supports. Examples:
- 45° Bevel Bending for Sofa Legs: Angle deviation ≤±0.3°, ensuring furniture verticality ≤1° after installation.
- Closed-Loop Structure for Dining Table Supports: 360° rotational bending reduces welding processes, cutting material waste by 30%.
-
Flexible Production Data Management
- 4,000 Process Libraries: Stores full-series specification parameters for sofa legs, coffee table supports, cabinet feet, etc. Retrieving historical order parameters takes only 3 minutes, adapting to the furniture industry's demand for multi-variety, small-batch production.
- Optimized Touchscreen Programming: Built-in support leg graphic libraries allow furniture designers to generate bending paths via drag-and-drop, eliminating the need for coding and boosting proofing efficiency by 70%.
Comprehensive Analysis of Furniture Support Leg Production Processes
-
Large-Diameter Wire Pretreatment Process
1.1 Wire Straightening Process- A 9-roller straightening system (roller diameter φ80mm) uses 0.8MPa light pressure for 6mm wires and 1.5MPa heavy pressure for 12mm wires, achieving straightness control within 0.1mm/m. This ensures scratch-free surfaces and uniform arcs on the supports.
- The straightening rollers are hard chrome-plated (thickness 8-10μm) with a wear life of over 150,000 cycles, suitable for continuous production in furniture factories.
1.2 Fixed-Length Cutting Process- A 2.3kW cutting servo drives an oblique blade cutter (shearing angle 10°). The cutting force for 12mm iron wires is controlled at 15kN±1kN, resulting in an end surface roughness Ra≤25μm with burr-free cuts, reducing subsequent grinding processes.
-
Typical Forming Case (10mm Iron Wire Dining Table Support)
- Feeding servo conveys 800mm of wire → 9-roller straightening system performs secondary alignment.
- Outer die rotates to 45°, inner die moves up to position the starting point.
- Bending servo drives the outer die to rotate 90° counterclockwise to complete the corner bend.
- Feeding servo conveys another 600mm for the second bend.
- Cutting servo acts to cut the wire, and the finished product is transferred to the quality inspection station by a robotic arm. Single-cycle time: 9.5 seconds, 3.5 times more efficient than manual bending, with joint gaps ≤0.8mm.
-
Quality Control System
- Load-Bearing Test: 12mm iron wire supports undergo an 800kg static pressure test with no deformation at the bends, complying with GB/T 3324 furniture mechanics standards.
- Precision Sampling: Five pieces are randomly inspected per hour using a coordinate measuring machine. When the bending angle deviation of 10mm wires exceeds 0.5°, the system automatically calibrates die parameters.
