PBA + 3D Aluminum Profile Bending Machine

PBA + 3D profile bending machine is suitable for roll bending different cross-section profiles. PBA + 3D has 3 sets of rollers, and 2 sets of guide rollers, photoelectric positioning; Through the rollers matching the section of the profile (such as aluminum, steel), using the principle of the three-point circle, the displacement (Y-axis direction) of the middle roller (pressure roller) is automatically controlled, so that the profile can be bent between the three sets of rollers at one time Forming or multiple bending forming (X-axis direction) to the required radius; Through the automatic lifting of the guide roller (Z-axis direction), the profile forms arcs with different curvatures in the Z-axis direction, so as to achieve the required three-dimensional bending effect; The length of the feed is collected by the encoder, and the rotation of the roller is controlled by the motion control system, which automatically matches the linear speed of the roller; At the same time, the displacement of the roller, the feed rate of the intermediate pressure roller, and the height change data of the supporting roller adopt a fully closed-loop numerical control AC servo control system to meet the requirements of high thrust and high precision.

Structure and Advantages

Shaft seat slideway (Chinese patent)

  • Steel plate quenching and tempering treatment, quenching treatment, and dovetail groove structure connection, each surface is processed by a grinding machine, after the combination, the upper and lower planes are processed by a grinding machine, and the surface is electroplated with hard chrome.
  • High strength, good structural stability, and can withstand particularly large tensile forces.
  • The minimum distance between the fixed wheels on the left and right sides can be adjusted to 270mm, and the minimum bending radius is 100mm

X-axis rotation transmission mechanism (Chinese patent)

  • Each roller spindle drives a planetary reducer through a CNC servo motor, and the planetary reducer drives the mold spindle to rotate
  • The speed ratio can be automatically configured to ensure that the linear speed of the roller mold is consistent
  • It has a large driving torque and is suitable for bending large cross-section profiles.

Z-axis lifting mechanism (guide roller) (Chinese patent)

  • Structure: The lifting reducer and guide device are controlled by the servo motor to realize the precise movement of the Z axis up and down;
  • Advantages: This structure is easy to adjust and has a high positioning accuracy

Y-axis propulsion mechanism (Chinese patent)

  • Structure: The CNC servo motor drives the special reducer, and the special reducer drives the linearly movable reducer to realize the precise positioning of the intermediate spindle.
  • Advantages: High-precision positioning can be guaranteed when the spindle advances and retreats, and it is suitable for highly difficult variable curvature arc processing.
  • Operation screen (Chinese patent)
  • Can slide left and right and rotate the operation screen
  • It is convenient to observe the process of feeding and discharging while operating.
  • The appearance of the machine is beautiful, the surface of the frame and the guard plate is pickled, phosphate, and electrostatically sprayed;
  • The three axes are all driving shafts, and all have “anti-tilt” devices
  • European standard electrical system

Software function

  • The workpiece can be rolled bent and formed at one time; it can also be bent and formed repeatedly in various forms according to the needs;
  • Bendable shapes: C-shape, U-shape, 3R-shape, ellipse, and various arcs with variable curvature symmetrical on both sides; parabola, Archimedes spiral, and various asymmetrical arcs with variable curvature.
  • Support USB import of 2D drawing DXF file, 3D drawing. STEP file USB import, and directly generate production and processing formula program and automatically assign address; formula data can be manually modified, and formula data can be exported through USB;
  • The interface operates and displays a 3D simulated three-dimensional arc, and the color changes synchronously to display the processing process; the simulated arc profile can be opened, zoomed, and rotated.
  • It can realize the three-axis linear interpolation function of the X-axis, Y-axis, and Z-axis, display the position change data of each action axis and workpiece movement data on the screen, and monitor the interpolation effect at any time to ensure the real interpolation function.
  • The equipment reserves an Internet communication interface, which can be used for remote online monitoring, remote debugging, online upgrade, etc.
  • The data of each axis has a power failure memory function and a permanent data storage function to prevent data loss due to power failure, shutdown, or equipment failure.
  • Automatically detect errors and equipment failures, and display errors, failure content, and codes on the screen, which is convenient for operators to troubleshoot easily.
  • Servo parameters can be preset through the system, and key parameters and the status of the servo can be monitored through the system.
  • The software can automatically extract material rebound data and interpolation arc length data of different radii, without manual input one by one, which effectively saves programming time and reduces the difficulty of equipment operation.
  •  Self-diagnosis function: if the equipment fails, it can judge whether the components are good or bad
  • Manual adjustment function: the arc with inaccurate size can be corrected by manual function.
  •  4G memory, 128G solid state hard disk, can store enough processing formulas for multiple profiles.
