The wire bending machine is a device used to bend metal wires into a set angle or shape. Its working principle mainly includes the following key steps:
Basic workflow
1.Thread delivery
The wire is precisely fed into the processing position according to the set length through the wire feeding mechanism.
Usually driven by servo motors or stepper motors, the rollers achieve high-precision wire feeding control.
2.Clamp
After the wire reaches the designated position, the clamping device fixes the wire to prevent sliding or displacement during the bending process.
3.Bend
Bending mechanisms (such as bending arms and molds) rotate under the drive system (hydraulic, pneumatic, or servo motors), applying pressure to the wire to produce plastic deformation and achieve the set bending angle.
4.Reset and discharge
After the bending is completed, the bending arm and clamping device are reset.
The finished wire is pushed out or manually/mechanically removed to complete a processing cycle.Key technical principles
1.Servo control technology: used for precise control of wire length and bending angle to ensure machining accuracy.
2.CNC (Numerical Control System): By programming and setting processing parameters such as angle, length, and speed, complex shapes can be formed in one go.
3.Mold matching: The mold determines the bending shape and surface quality of the wire, and different products require different molds to be configured.
Multi axis linkage: The high-end bending machine adopts a multi axis control system, which can achieve continuous bending in multiple directions and angles, and complete three-dimensional forming.
Classification of driving methods
1.Hydraulic drive: Strong force, suitable for processing coarse wire, but slow response speed and complex maintenance.
2.Pneumatic drive: suitable for lightweight wires, with fast response and simple maintenance, but with less force.
3.Servo motor drive: high precision, fast response, suitable for high-precision and complex shape processing, is currently the mainstream development direction.
Typical application examples
1.Processing circular springs: Achieving equidistant spiral forming through continuous wire feeding and rotational bending.
2.Processing irregular parts, such as chair back brackets, plug-in pins, etc., to complete complex structures through multi axis linkage and CNC programming.
The working principle of the bending machine combines mechanical transmission, automatic control, and material processing technology. Modern bending machines are developing towards high precision, high efficiency, intelligence, and flexibility.
Market demand continues to rise, and 3D wire bending machines have become a must-have equipment for multiple industries
The rise of domestic 3D wire bending machines breaks the international technological monopoly and continues to increase market share
