2.Each process:
Material preparation
1)Before cutting the plate, first adjust the inclination to meet with required vertical shears.
2)Fix the position of steel plate, assure maximum excess material.
3)The length is decided when laying up the plate. The size of bottom should not more than ±2mm, but for high mast the tolerance should be plus, usually: 0 to 2m, for small ending, the tolerance should be minus, usually -2 to 0mm. When adjust is ready, the cutting machine will finish cutting.
4) About equipment: check condition of roller shear, clean sundries on the track, maintain good conditions.
Bending
The work of bending is the most important process, which will directly influence the quality of pole, and the finished product cannot be repaired. Pay attention to following tips:
1)before bending: remove residues to keep new plate away from damage
2)check the length, width and straightness of plate, the non-straightness should be less than 1/1000, if the non-straightness meets requirement, correct, especially the polygon poles must keep non-straightness.
3)adjust the depth of bending with the bending machine, and confirm the location of plate.
4)Correctly mark line on the plate, the tolerance should be less than ±1mm.
5)Correctly line up and bend to keep min seam, meanwhile the distance between two sides should be less than 5mm.
Welding
Weld the seams of bended plate. As it is semi-auto welding ,the welder has more work to do, he should adjust the position of welding and assure straightness of line.
