The technological process of lamp pole production can be roughly divided into the following points: 1, rolling shearing and blanking. 2, bending machine bending into a cylinder. 3. Seam welding will merge the cylindrical gap. Welding flanges and electric doors, etc. 4. Straightening (post-welding deformation) and bending (not required for auxiliary mechanical straight pipes) 5. Grind with a grinder. 6. Paint or electroplate the surface through electrostatic spraying production line. 7. The same electrical appliance factory. 1. Roll cutting is to cut the material into a trapezoid as shown on the right. The materials used in this process are in the range of δ 3 to δ 8. The equipment used is as follows. Second, the bender bends into a tube. The length of trapezoidal material is manufactured according to the requirements of users. Due to the different thickness of the materials used, the size of the bending machine he chose ranged from 160 tons to 600 tons, and the length ranged from 12 meters to 14 meters. Longer ones can be customized, such as16m. Is the selected equipment as shown on the left? Bending the mould into a cylindrical shape is shown in the figure on the right. When the material is removed, it is removed through the side of the bending machine. Third, seam welding will merge cylindrical gaps. This process is naturally easy to understand. As the name implies, it is to weld the materials bent into pipes together.
