CNC Servo Bending Machine

DW25CNC-3A-1S fully automatic CNC pipe bending machine

*Rich experience in bending process and advanced mold design and manufacturing.

*Electric control system: using Mitsubishi servo drivers, servo motors, positioning modules, CPU, etc., with strong performance and good stability

*Mitsubishi's ultra large CPU can accommodate 1000 sets of file editors,

*Equipped with automatic error and fault detection function, and displayed on the screen, making it easy for operators to eliminate obstacles

*The machine is equipped with an automatic oil filling system, which can reduce the friction of the bent pipe, improve the service life of the core rod, and ensure the quality of the bent pipe

*The control uses a Japanese Mitsubishi programmable controller.

*Electrical control can achieve three functions: jog, single action, and automatic.

*Adopting an integrated path block structure, the hydraulic system has high reliability.

*Equipped with a core rod mechanism, it can be bent with or without a core.

*Equipped with safety limits and emergency stop buttons to ensure the safety of operators.

*Changing the mold can bend various profiles.

*The clamping and core rod parts are both equipped with separate oil cylinder drives. When the bending arm rotates, the pipe can achieve high-precision bending and forming under the joint constraints of the above parts and the mold parts.

The structural composition of the machine includes the bed part, main transmission part, clamping part, guiding part, core rod mechanism, hydraulic system, electrical system, mold part, feeding part, and corner part

1. Bed body part

The bed body is a bent welded structure that serves as a carrier for other parts.

2. Main transmission part

The main transmission part consists of a spindle, a sprocket, and a servo, which can achieve bending and return movements.

3. Clamping section

The clamping structure is used to clamp the pipe, which rotates with the spindle to make the mold and pipe fittings rotate simultaneously.

4. Guiding section

The guiding mechanism supports the straight part of the pipe during the bending process, and during the bending process, the pipe moves forward with the guiding die. The clamping action of the clamping guide structure is driven by a hydraulic cylinder, and by opening the side peephole cover plate, it can be inspected, repaired, and adjusted.

5. Core rod section

The core rod mechanism is located at the rear of the bed, and the required bending radius of the core rod can be adjusted through screw transmission. The action of the core rod is achieved by the core rod and oil cylinder, and the leading amount of the core rod can be adjusted by adjusting the nut. The bed is equipped with a core rod support device, support core rod, and pipe fittings. If there is no core bending, the core rod can be removed.

6. Hydraulic system

The control components of the hydraulic system are imported from Taiwan, and the hydraulic system adopts an integrated passage block structure. The hydraulic pipelines are made of seamless steel pipes, and high-pressure hoses are used at the movable connections. U-shaped quick fittings are used to prevent system leakage and improve the reliability of the hydraulic system.

7. Electrical system

The electrical system is powered by a 50HZ, 380V three-phase AC power supply, and the control line is routed through a 380/110V control transformer to control the operation of contactors, intermediate relays, and solenoid valves. The main electrical components are imported brands, and the power line is mainly driven by a Y-series three-phase asynchronous motor to drive the hydraulic system. The main control components are microcomputer program controllers, and all control button signals come from the safety and strong electrical cabinet.
