the curtain wall profile bending processing technology

Curtain wall profile bending process, quality assurance measures and handover acceptance is to ensure that the quality of the curtain wall project and an important part of the performance.

First, the curtain wall profile bending processing technology

1. Material selection: lightweight, high-strength aluminum alloy materials are usually selected because of its good corrosion resistance and shape stability, suitable for bending processing.

2. Bending equipment and technology: the use of professional bending equipment, such as CNC machine tools, in order to improve processing accuracy and efficiency. In the bending process, the need for accurate calculations and adjustments according to the design drawings to ensure that the bending degree and angle of the profile to meet the requirements.

3. Process parameter control: including mold design, temperature control, bending speed adjustment, etc., in order to reduce stress concentration, avoid deformation and cracks.

4. Surface treatment: After bending the profile surface treatment is required to improve corrosion resistance and aesthetics.

Second, quality assurance measures

1. Management of equipment and measuring instruments: processing equipment and measuring instruments need to be regularly inspected and metrological certification to ensure processing accuracy.

2. Mold design and optimization: Reasonable design of the mold to avoid deformation or cracks in the profile in the process of bending [.

3. Strict control of process parameters: through testing and experience accumulation, optimize the bending process parameters, such as bending radius, tensile force, etc., in order to reduce rebound and dimensional deviation.

4. Surface quality monitoring: Surface treatment of the mold, the use of lubricants to avoid scratches and indentations.

5. Segmented bending and support fixing: for large, complex profiles, the use of segmented bending methods, and the use of support fixing to reduce the deformation stress.

Third, handover acceptance

1. Appearance inspection: check the surface of the profile for cracks, wrinkles, scratches and other defects to ensure that the appearance is intact.

2. Dimension measurement: Use gauges to measure key dimensions, such as length, angle, radius of curvature, to confirm compliance with design requirements.

3. Bending strength test: Evaluate the deformation behavior and stress level of the profile during the bending process to ensure that its bending strength meets the requirements.

4. Impact test: Evaluate the toughness and impact resistance of the profile to ensure that it is not easy to break or be damaged in actual use.

5. Digital Inspection: Use three-dimensional scanning technology to inspect the profile, capture the surface contour and deformation condition, and improve the processing accuracy and qualification rate.

IV. Common Problems and Solutions

1. Wrinkle and rupture: Solve it by adjusting the shape of the mold, increasing the tensile force, optimizing the process parameters and other measures.

2. Cross-section deformation and rebound: Reasonable design of the mold, the use of support and fixation, predict the amount of rebound and compensation.

3. Surface scratches: Surface treatment of the mold, use of lubricants, strengthen the operation monitoring.

4. Dimensional accuracy problem: Strictly control the process parameters, regularly test the mold and strengthen the dimensional inspection.

The processing technology of curtain wall profile bending needs to be strictly controlled in many aspects, such as material selection, equipment management, process parameter control, etc., in order to ensure the processing quality and precision. At the same time, the qualified rate and reliability of the product can be further improved through digital detection and quality inspection methods. In the handover and acceptance link, it is necessary to check in strict accordance with the relevant standards and specifications to ensure that the profile meets the design requirements and use standards.
