1、Light Poles Head Bending Machine Description
In order to maximize the illumination area of the street lamp, the head of the street lamp pole is generally bent into an arc shape.
When the elevation angle of the street lamp pole is large, the light source of the street lamp will turn to the other side of the road, and the light source will diverge, resulting in poor lighting effect; Similarly, if the elevation angle of the street lamp pole is too small, the light source of the street lamp can only shine on the roadside, and only on the green belt if there is a green belt. According to practice, it is most appropriate that the elevation angle of the street lamp pole is about 15 degrees.
The equipment is composed of main board and bending die, with two sets of dies. The straight die bends the steel rod pressed on the round die along the arc surface under the traction of the motor reducer. It is simple to operate, without heating and filling. It is economical and affordable. It has the same effect as the large pipe bender in this industry. It is the equipment of the steel rod manufacturer.

How to select welding method and welding wire when welding thin wall street lamp pole?
The specification of the street lamp pole is determined according to the height of lamp pole. The height of the street lamp pole is related to the wall thickness of the street lamp pole and the diameter of the upper and lower.
The street light pole is generally made of high-quality low-carbon steel Q235A (Si≤0.04%, yield strength＞245Mpa). As the wall thickness of the street light pole is relatively thin (no more than 8mm), CO2 gas shielded welding or submerged arc welding is generally used.
When submerged arc welding is selected, the diameter of solid wire submerged arc welding is 1.2/1.6/2.0 mm. When welding thin plates, when using small diameter welding wires under the same current, the weld penetration is better, the weld penetration is smaller, and the weld formation is more beautiful. The diameter of welding wire is closely related to welding current, welding voltage and plate thickness. Common varieties of submerged arc welding wire are H08A, H08MnA, and HJ431 is used as welding flux.
Why are street light poles tapered?
1. Conical street lamp pole has better mechanical strength and can resist strong wind.
2. Conical street lamp pole can save materials and reduce cost compared with round pole.
3. The tapered street lamp pole is convenient for workers to install up and down, and is more beautiful and generous.
How to calculate the taper ratio of street light pole?
Compared with large/small rods and straight rods, the manufacturing process of taper rods is more complex, but the taper rods have the advantages of good wind resistance, high strength and beautiful appearance. The taper ratio of the taper bar refers to the ratio of the taper bar (diameter difference between the lower and upper diameters) to the height of the taper bar.
For example, the taper ratio of street light pole with lower diameter of 132mm, upper diameter of 60mm and height of 5800mm is:（132-60）/ 5800=12.41:1000
The normal taper ratio is (10-15): 1000, and the international standard is 12:1000.
How to ensure the welding gun and the weld seam keep a fixed distance when welding the cone street lamp pole?
The welding gun is fixed on the cross-slider. Cross-slider and flux conveying/recovery system are fixed on the lifting rack of the upper clamping wheels which follows the upper clamping wheel. Adjust the upper/lower, left/right distances between the welding gun and the weld seam through cross-slider, so that the welding gun is aligned with the weld seam finely. The clamping wheel is composed of three wheels that can swing, so as to ensure that the clamping wheel can be stuck to the surface of the street lamp pole to the greatest extent when the tapered pole is welded.
What is the Maximum diameter of an ordinary street lamp pole?
The height of the street lamp pole used in the neighbourhood, school is 3-6 meters; The height of street lamps on rural roads is generally 6-12m; The height of street lamps in urban areas is generally 8-12 meters; The center of the square generally uses a 12-15m medium pole; The wharf and parking lot uses a 15-20m high pole.
Take the 20m high pole as an example, and make it in two sections:
The upper section is 10m: the wall thickness is 6mm, the upper opening diameter is 220mm, and the taper is 12/1000, so the lower opening diameter is 10000 * (12/1000)+220=340mm.
The lower section is 10m: the wall thickness is 8mm, the upper opening diameter is 360mm, and the taper is 12/1000, so the lower opening diameter is 10000 * (12/1000)+360=480mm.
Therefore, the maximum diameter of the street lamp pole is generally not more than 500mm. When we design, the maximum diameter is generally 550mm. It is convenient for customers to use.
