PBA-500 CNC Aluminum Window Frame Bending Machine

The PBA-500 CNC profile bending machine is suitable for processing different cross-section profiles. The PBA-500 CNC Aluminum Window Frame Bending Machine has 3 sets of rollers and photoelectric positioning;

Aluminum Window Frame Bending

Bending aluminum window frame extrusions can be some of the most simple to bend aluminum sections, or they can be incredibly difficult. Arched aluminum window frames add an incredible amount of character to any structure. Just looking at these frames does not express the incredible process that goes into producing them. This all depends on the extrusion used, the shape of the window, and the tightest bending radius to be achieved.

Bending after powder coating, and bending sections to an incredibly tight radius, are the jobs that many aluminum bending service companies avoid.

Another difficult aspect could be if need to bend aluminum sections after powder coating. Having the section pre-coated introduces the possibility of chipping, scratching, or cracking the finished surface.

These beautifully curved sections were produced with no markings on the existing powder-coated surface and our customers could not be happier with the result of the BIT PBA Aluminum Window Frame Bending Machine for the curved aluminum extrusion bending.

PRINCIPLE of CNC Aluminum Window Frame Bending Machine

The PBA-500 CNC Aluminum profile bending machine is suitable for processing different cross-section profiles. The PBA-500 CNC profile bending machine has 3 sets of rollers and photoelectric positioning;

Through the rollers matching the section of the profile, using the principle of the three-point circle, the displacement of the middle roller is automatically adjusted, so that the profile is fed once or multiple times between the rollers, and the profile is formed to the required radius one by one.
The length of the feed is collected by an encoder, and the rotation and feed of the rollers are controlled by a program controller. At the same time, the displacement of the rollers and the feed of the intermediate rollers are controlled by a fully closed-loop digitally controlled AC servo control system to achieve the curved arc height. Precision requirements.

Structure And Advantages of PBA-500 CNC Aluminum Profile Bending Machine

Axle slide

The steel plate is quenched and tempered, and the dovetail groove structure is connected. Each surface is processed by a grinder. After the combination, the upper and lower surfaces are processed by a grinder, and the surface is electroplated with hard chromium.
The structure has high strength, good structural stability, and can withstand particularly large tensile forces.
The minimum distance between the left and right fixed wheels can be adjusted to 270mm, and the minimum bending radius can be 60mm

X-axis rotation transmission mechanism

The secondary reducer is driven by the CNC servo motor, and the reducer drives the mold spindle to rotate through the universal driveshaft
It has a large driving torque and is suitable for bending large cross-section profiles.

Y-axis propulsion mechanism

Structure: The special speed reducer is driven by the CNC servo motor, and the special speed reducer drives the linearly movable speed reducer to realize the precise positioning of the intermediate spindle.
Advantages: The positioning accuracy (≤0.01mm) can be ensured when the spindle is moving forward and backward, and it is suitable for difficult variable-curvature arc machining.
The operation screen can be slid left and right, and the operation screen is convenient to observe the process of feeding and discharging at the same time.
The appearance of the machine is beautiful, the surface of the frame and the guard plate is pickled, phosphate, and electrostatic sprayed;
All three axes are active axes, and all have “anti-tilt” devices

Software Function of PBA-500 CNC Aluminum Window Frame Bending Machine

  • The profile can be rolled and formed at one time; it can also be bent and formed repeatedly as required;
  • Bendable shapes: C shape, U shape, 3R shape, multi-segment arc program (two-dimensional variable curvature), etc.
  • Automatic calculation function of the rebound amount of the profile (the bending radius of the first profile is inaccurate, and the second profile can be bent accurately according to the calculation result)
  • Auxiliary calculation: knowing the chord length and chord height, the radius and arc length can be obtained
  • Self-diagnosis function: equipment failure can judge the quality of components
  • Manual adjustment function: inaccurate size arc can be corrected by manual function
  • The interface has the ability to switch between Chinese and English, and provide prompts and alarm information;
