5. Leveling unit:(two lay type)
It is composed of frame part, work roll part, lifting part and main driving part.
The frame part adopts the steel plate welding structure, and the work roll part, the lifting part and the frame part are organically combined.
The work roll is composed of leveling rolls.
The leveling roller adopts the parallel type of roller rows. The upper roller can move up and down and can be inclined relative to the lower roller. The opening size of the entrance and exit can be adjusted separately to achieve the ideal leveling effect. The material of the leveling roller is surface hardened.
The main function of the lifting part is to lift the upper row of leveling rollers and adjust the pressing amount between the leveling rollers. The motor of this machine achieves the purpose of lifting the upper row of rollers through the reducer, worm gear and worm drive screw nut.
The main driving part is driven by a variable frequency AC motor through a reducer to drive the leveling roller.
On the discharge side of the leveling machine, an independent encoder pneumatic pressure measuring device is installed. The rotary encoder detects the size of the feeding cut-to-length and cuts and controls it through the electrical system.
6. Shearing machine, rotation type
Shearing machine is a device for cutting the leveled steel plate in the production line.
Machine structure and characteristics description: steel plate welding, high strength, good rigidity, hydraulic up and down tool holder, stable and fast movement. The lower blade has a front and rear fine-tuning mechanism, the knife edge gap uniformity is good, and the cutting straightness accuracy is high. The blade gap adjustment is convenient and quick, the left and right sides are synchronized, and the scale value is indicated. The hydraulic pressure material is stable and gentle, and the pressure foot pad is made of polyurethane material, which does not damage the surface of the workpiece.
The shearing machine has an integral rotation function, which can rotate relative to the center line at a certain angle, so that the cutting sheet is a parallelogram, which is convenient for the taper slitting to obtain an isosceles trapezoidal sheet after oblique cutting, suitable for the production of street light poles.
7.Pole length supporting table , guiding trolly :
There is a dolly in the front of the edge slitting unit. It is for control the slitting straight and parallelogram plate size. By change the position of the stopper on trolly to control the parallelogram plate width .
Both on trolly and in the front edge slitting unit, there are mechanical stop to get right dimension of the parallelogram plate.
Clamping unit is manual type.

The edge slitting machine is base on the rolling shearing principle to cut the steel sheet.
It is for slitting scrape edge of the hot rolled steel plate to get the exact width for light pole.
If the plate width suitable for four pieces pole., the middle blade can cut the plate to two big pieces.
Including : two pairs pinching rollers, Motor, gear box, Up and down two screw type rollers, with 3 pairs of slitting blade.
screw type rollers is easy for adjusting the cutting blade to any position for slitting any size of plate.
9.Pole length supporting table , guiding trolly :
There is a dolly in the front of the taper slitting unit. It is for control the slitting straight and the plate width after taper slitting. By change the position of the stopper on trolly to control the Isosceles trapezoidal plate width. Both on trolly and in the front taper slitting unit, there are mechanical stop to get right dimension of the plate.
Clamping unit is manual type.
10.Taper slitting unit. (one pairs cutting blades type)
The taper slitting machine adopts the principle of rolling shear.
On the unit, the parallelogram sheet can be cut obliquely into Trapezoidal sheet with a big end and a small end(Trapezoid) required by the street light pole.
Including : two pairs pinching rollers, Motor, gear box, Up and down two screw type rollers, with 1 pairs of slitting blade.
screw type rollers is easy for adjusting the cutting blade to any position.
11.Output supporting table
This is third supporting table
The length of this table is the same as the length of the longest street light pole that needs to be produced. The table consists of a table top, a supporting shelf, and a rolling ball on the table top.
The ball on the table is universal, which facilitates the longitudinal and lateral movement of the steel plate.
After oblique shearing, the trapezoidal sheets with one big end and the other small, which are needed by the street light pole, are located on the table. The operator moves the sheets to the customer’s own lifting tool. After stacking multiple sheets (such as 20~30 pieces sheet), once hoisted to the press brake of the next bending process.
