Key Technical Points Of Outdoor Light Pole Bending Process

Bending is one of the main processes in the manufacture of outdoor light poles, which directly affects the verticality, roundness, flatness and structural stability of the pole. Also it is important to avoid problems such as bending deformation, misaligned joints and poor load bearing capacity. The whole process needs to be divided into two main levels, pre-bending preparation, and actual bending operation and post-processing. The technical details must be strictly controlled to ensure that the final product meets the standards of municipal engineering. Let's follow road light pole supplier Phoebus.

I. Pre-bending Preparation

The accuracy of bending is basically determined in the pre-bending preparation, which mainly includes two key points: material screening and equipment debugging. The first step is to screen the material. The material of the special outdoor light pole should be uniform, without peeling, cracks or uneven thickness, such as carbon steel and aluminum alloy. The wall thickness shall be strictly controlled within ±0.2mm to prevent the deformation and springback after bending caused by the material quality problems. The second point is equipment debugging. The parameters of the pressure, bending angle and stroke of the bending machine should be adjusted according to the taper, height and pipe diameter of the road light pole. For tapered poles the gradual bending parameters need to be matched. Meanwhile the equipment level and die accuracy must be calibrated to avoid die wear and misalignment, which could lead to indentations and edge collapse. In addition, the impurities and oil stains on the surface of the sheet metal should be cleaned in advance to prevent scratches during bending, which may affect the anti-corrosion coating effect.

II. Bending Practice and Post-Processing

In the process, bending practice is the core, which needs accurate control of bending rhythm and parameters. Adopt progressive bending process, prohibiting one time heavy pressure bending. For high thick wall poles , the segmented bending is performed several times to gradually form the pole . This method can effectively compensate the springback stress of the sheet metal , and make the road light pole straight and curvature uniform. During the bending process the angle and taper are monitored in real time. Flatness and verticality are checked with professional measuring tools after each bend, and equipment parameters are fine-tuned as needed to avoid angle deviations and pole twisting.

After the bend, it's time for the finishing touches. First, the bending joints are trimmed for tightness, no misalignment, and no gaps, which is the basis for the subsequent welding. Secondly, the bending edges are ground off to remove burrs and sharp edges, so as to avoid the accumulation of dust and corrosion during later usage. Finally, rebound test is conducted, and the second correction is conducted after cooling to avoid natural deformation of light pole later. The finished product meets the requirements of wind and pressure resistance and outdoor municipal lighting projects.

Road light pole supplier Phoebus specializes in the production of various kinds of road light poles, strictly controls the core bending process, and ensures superior quality, and provides comprehensive warranty services. We adopt a segmented progressive bending method to effectively fight against sheet metal rebound, accurately control taper, angle and straightness, and make a neat and uniform pole shape without twisting or deformation. Then the joints and edges are processed with tight and smooth welds. The whole structure is stable and is resistant to wind. From raw material to finished product, each layer is quality inspected to assure solid and durable workmanship, adequate corrosion protection, ample stock and support for customization. Quality of the project is guaranteed, after-sales service is worry-free, you can buy with confidence.
