Street lights are generally divided into high pole lights, landscape lights, garden lights, lawn lights, road lights, searchlights, floodlights and other types. They are non-standard customized products and therefore have no fixed size. The general height of street light poles is generally between 2.8 and 3.8 meters. We generally use a three-roller horizontal lower-roll machine for the following processing:

1.Adjustment of rollers of three-roller horizontal lower-roll machine
Adjustment of the spacing between the upper and lower rollers of the plate rolling machine: adjust the spacing between the upper and lower rollers according to the thickness of the street light pole. Generally speaking, the spacing should be slightly larger than the thickness of the plate so that the plate can smoothly enter between the rollers. For example, for a street light pole with a thickness of 3 mm, the spacing between the upper and lower rollers of the plate rolling machine can be adjusted to about 5 mm.
Adjustment of the side roller position of the plate rolling machine: adjust the position of the side roller so that it is parallel to the upper and lower rollers and aligned with the edge of the plate. The function of the side roller is to control the deformation of the plate in the width direction and ensure that the cylindrical shape after rolling is regular. For example, by adjusting the screw mechanism of the side roller, the side roller is in close contact with the edge of the plate.
Adjustment of the parallelism of the rollers of the plate rolling machine: use tools such as a level to check the parallelism of the rollers. Make sure that the four rollers are on the same plane to avoid twisting or deformation of the street light pole during rolling. For example, by adjusting the mounting base of the roller, the parallelism error of the roller is controlled within a certain range.
2.Rolling process control of three-roller horizontal lower-roll machine
Rolling machine loading: Use lifting equipment or manpower to place the street light pole steadily on the feed end of the horizontal plate rolling machine. Make sure that the center line of the street light pole is aligned with the center line of the roller to avoid the plate from shifting during the rolling process. For example, for larger-sized street light poles, a crane can be used for loading, and the operator should work closely to ensure accurate placement on the roller.
Rolling machine rolling speed control: Adjust the rolling speed of the three-roller plate rolling machine according to the material, thickness and rolling requirements of the street light pole. Too fast speed may cause uneven deformation of the plate or overload of the equipment, while too slow speed will affect production efficiency. Street light poles can use a lower speed.
Rolling machine pressure control: Adjust the pressure of the plate rolling machine. Too much pressure may cause excessive deformation or damage to the street light pole, and too little pressure will not achieve the desired rolling effect. The thickness of street light poles is commonly 2mm, 2.5mm, 2.75mm, 3mm, and 3.5mm. The pressure should be appropriately reduced to avoid indentation on the plate to ensure that the plate can fit the roller tightly.
Shape control of the plate rolling machine: During the rolling process, closely observe the shape changes of the street light poles and adjust the position and pressure of the side rollers in time to control the bending radius and roundness of the plate. For example, when the plate is found to be ovality or distortion, the position and pressure of the side rollers should be adjusted in time to make the shape of the plate more regular.
After determining the material, the next step is to choose the plate rolling machine. Here, Shanghai ANTISHICNC engineers recommend a three-roller horizontal lower-roll machine suitable for processing street light poles within 4m in height. The model reference is as follows:
Model | W11X-160×4000 |
Upper roll diameter | Φ1280mm |
Maximum rolling thickness | Φ160mm |
Maximum rolling width | 4000mm |
Rolling speed | 3m’min |
Maximum pre-bending thickness | 130mm |

This W11X-160×4000 three-roller horizontal downward adjustment plate rolling machine has strong forming capabilities. For the pre-bending of street light poles, only one loading is required. The right-angle edges are small, and the material plates can be shaped and flattened directly on the equipment.
