CNC variable geometry three roll plate rolling machine adopts the structure of oil cylinder down. The upper work roll of the wind tower bending machine is the main driving roll: the upper roll is driven by the hydraulic motor (one motor) through the planetary reducer, and the two lower rolls are driven by the hydraulic motor planetary reducer respectively. The lifting of the upper roller is realized by a hydraulic cylinder, the lifting displacement is controlled by computer, automatic leveling, screen display, and synchronous precision ± 0.2mm.
The horizontal position of the two lower rollers can be adjusted independently, the horizontal movement adopts hydraulic transmission, and the center distance can be adjusted; The rolling cone stop is installed on the bearing seat of the lower roll on the overturning side to slow down the small end of the sector plate and realize the cone rolling in a certain range; General cone angle 30 °, 50% of full load. The tail part of the upper roll is equipped with a balance mechanism, which can easily unload the rolled workpiece and cylinder. The wind tower bending machine is equipped with a fixed console and a remote control button box, which is convenient for workers to use. And the wind tower bending machine is equipped with a safety interlock device to make the operation safer. The steel plate bending machine is simple to operate, easy to maintain, high rolling accuracy is an advanced and practical large plate rolling equipment.
- High-efficiency rolling speed, increase productivity, and can complete a cone roll in 20-30 minutes;
- The full set of coiling system of the EZHONG wind tower bending machine only needs one operator to complete;
- High-precision rolling, the pre-bending, and rolling of the cone can be completed only through one-time rolling;
- The machine tool is powerful and reliable, and the EZHONG wind tower bending machine produces at least 200 complete wind towers every year;
- The upper support does not require any additional overhead lifting equipment for the machine tool, and the upper support can automatically tilt according to the cone angle;
- When the sheet metal forming machine is combined with a hydraulic clamp, it can automatically correct the plate and facilitate spot welding;
- The advanced feeding table can automatically adjust the plates, without the use of overhead cranes to adjust the plates;
- The feeding side support is equipped with a cylinder body error correction device, which can correct the axial and radial misalignment of the cylinder body (pipe section misalignment and correcting device), and the increase of the gripper pair can grasp both sides of the plate and expand back and forth, which is convenient for the plate to be fast;
- EZHONG wind tower bending machine is equipped with a powerful CNC system, easy to operate, and PGS numerical control system can guide the operator to program.
Accurate measurement method of rolled cone parts
1. The length of the front straight end and the end edge after pre-bending: The most accurate machine tool is the wind tower bending machine with the smallest distance between the bending points, that is, the two side rollers and the bottom center roller (pinch roller) are as close as possible, Almost reached mutual contact.
2. The number of defective drums: The most accurate machine tool is the wind tower bending machine with a large diameter of rollers (upper roller, pinch roller, side roller). The large diameter roller can ensure small deformation under the pressure of the stick, and the thickness of the rolled plate is wide.
3. Consistency of taper angle: The inclination angle of the plate must be consistent during the entire rolling process, which is achieved by the most accurate CNC electronic leveling system.
High-efficiency rolling speed, increase productivity, and can complete a section of cone in 20-30 minutes;
The full set of coiling system of the EZHONG wind tower bending machine only needs one operator to complete;
The roller adopts high-strength and long-life solid bearing roller with long service life and small deformation.
The transmission gear is made of forged high-carbon steel, which has high hardness and strong wear resistance;
The whole wind tower bending machine adopts integral steel plate welding, which is thick and beautiful, and has good stability.
EZHONG wind tower bending machine used in wind power generation industry. The plate bending machine can rapid prototyping, high-precision coil, without auxiliary equipment, less investment.
