Cut To Length Line For Light Pole

Proprietary features:

1.The raw material is steel coil, and the output is isosceles trapezoidal plate suitable for the size of street light pole
2.Uncoiling, leveling, length cutting, edge removal, oblique shearing, unlading and stacking in one production line. It is a machine and a process. After the plate shears cross cut, there is no need to drive the crane for loading and unloading, and directly enter the oblique shear process. Reduce the number of operators, labor and improve the production speed.
3.Full automatic type, sheet length CNC control, sheet quantity CNC control, automatic oblique shear, automatic unloading and automatic stacking system.
4.The production speed is extremely fast, because the speed is far faster than the subsequent process. Generally, after this process is completed, the operators can work in other processes, which greatly saves working time and reduces production costs.
5.The operator shall be relaxed and minimize contact with the steel plate, which is safe for personnel.
6.The shearing machine has the function of overall rotation, which can rotate at a certain angle relative to the center line, so that the cut plate is parallelogram, which is convenient for the oblique shearing machine to obtain isosceles trapezoid plate after oblique shearing, which is suitable for the production of light pole. There is no need for trimming process to reduce sheet metal waste.
7.Three blade edge cutting device, which can remove the waste edge and cut the middle half at the same time when the sheet width can be used as four poles.
8.After oblique shearing, the plates in the same direction are stacked separately without sorting. Multiple plates (such as 30 plates) can be directly hoisted to the bending machine, which is safe and saves time.
9.The optional leveling unit after taper slitting , which can remove the stress caused by the taper cutting and make high-quality light poles.
