Production process:

一、Lamp post

1.1 Lamp post

In the whole cutting process, automatic plasma cutting with digital probe is adopted. The incision is fine and the cutting seam is less than 1 mm, which creates many favorable conditions for the follow-up process.

1.2 Forming

The 12 meter long CNC hydraulic bending machine is adopted, with high control precision, beautiful lamp pole forming, roundness no more than 1 mm, smooth appearance, forming more than 12 meters at a time.

1.3 Welding

Adopt numerical control automatic necking machine for welding. This equipment integrates the functions of closing and welding, and overcomes the influence of traditional spot welding on the integrity of the whole straight weld due to the need of spot welding for closure. The weld is formed once, and the surface is uniform, and the straightness is not more than 2%.

1.4 Plastic

In the whole production process of our factory, it is divided into two shaping. The first time is carried out after the longitudinal seam welding joint of the lamp pole is completed, which is conducive to the correctness of the lamp pole assembly welding and the consistency of the appearance of the whole batch of lamp poles; the second time is carried out after galvanizing and before plastic spraying, which is used to eliminate the bending of lamp pole caused by thermal stress caused by hot galvanizing. The straightness of finished lamp pole shall not be greater than 1%, and the total length shall not be greater than 5mm.

1.5 Galvanized

By adopting advanced galvanizing technology, technology and domestic advanced galvanizing equipment, the problems of poor adhesion and short service life of zinc titanium alloy metal are solved, which can only be a physical combination of spraying aluminum and zinc.

Our factory has fundamentally solved the following problems.

(1) SS400 steel plate is used.

(2) Strictly manage the galvanizing process and strictly control the pickling, galvanizing temperature and other technical parameters according to the national standard GB / t13912-92.

(3) Good galvanizing ensures the anticorrosion life of more than 30 years.

1.6 Spray molding

(1) Strictly comply with the requirements of spraying process after galvanizing, and spray technology is applied to the rod body before spraying to increase the adhesion and not damage the hot-dip galvanized layer.

(2) The curing time and temperature should be strictly controlled to ensure that the plastic layer is uniform, smooth and free of pores.

1.7 With door

(1) The distribution door is cut by CNC plasma cutting machine, which has the advantages of high precision and small cutting, and is integrated with the rod body.

(2) The pole door is equipped with grounding device and grounding wire.

二、Lamps and lanterns

2.1 Housing

2.11 ZL102 (gb1173-86) is used as shell material. After entering the factory, sampling inspection of chemical composition and mechanical properties is carried out.
