1. 板材卷制：

• 送料：将待卷制的板材送入三辊卷板机。一般通过人工或自动送料装置，使板材前端进入上下辊之间的间隙。

• 预弯：三辊卷板机的上辊可以垂直升降，下辊固定，两侧辊可水平移动。预弯时，上辊下降，对板材端部施加压力，两侧辊向中间移动，使板材端部产生一定的弯曲变形，形成预弯效果。这个过程主要是为了消除板材端部的直线段，使其在后续卷制过程中能够更好地贴合辊筒。

• 卷制：预弯完成后，上辊继续下降，使板材与上、下辊紧密接触。然后，上辊或下辊（通常上辊可驱动）转动，带动板材在三个辊筒之间滚动。两侧辊通过水平移动调整位置，使板材逐渐卷曲成所需的曲率半径。在卷制过程中，三个辊筒对板材施加的压力和摩擦力使板材发生塑性变形，从而实现卷制工艺。

• 成型：随着板材的不断卷制，板材逐渐卷成圆筒形或其他形状。通过控制上辊的升降、两侧辊的水平移动以及辊筒的转动，可实现不同曲率半径和形状的卷制要求。

2. 液压卸料：

• 液压系统：该卷板机配备了液压系统，主要由液压泵、液压缸、控制阀和油箱等组成。液压泵提供动力，将液压油从油箱中吸出并加压，通过管路输送到液压缸。

• 卸料操作：当板材卷制完成后，上辊上升至一定高度，以确保卷制好的圆筒可以顺利卸料。然后，启动液压卸料装置，液压油进入卸料液压缸，推动液压缸的活塞运动。液压缸的活塞杆与卸料装置（如卸料架或卸料辊）相连，活塞的运动带动卸料装置将卷制好的圆筒从卷板机的辊筒上卸下。在卸料过程中，液压系统可以精确控制卸料装置的动作，确保卸料平稳、安全，避免圆筒在卸料过程中受到损伤。

• 复位：卸料完成后，液压系统将液压缸的活塞收回，使卸料装置恢复到初始位置，准备下一次卷制和卸料操作。

  
  

• The working principle of the HT11W series mechanical upper-adjustable three-roll symmetrical plate bending machine with hydraulic unloading mainly consists of two stages: plate rolling and unloading. The detailed introduction is as follows:

  
  

• Plate Rolling:

  
  

• Feeding: Feed the plate to be rolled into the three-roll plate bending machine. Generally, use manual or automatic feeding devices to make the front end of the plate enter the gap between the upper and lower rolls.

  
  

• Pre-bending: The upper roll of the three-roll plate bending machine can be vertically lifted, the lower roll is fixed, and the two side rolls can move horizontally. During pre-bending, the upper roll descends to apply pressure to the end of the plate, and the two side rolls move towards the middle to cause a certain bending deformation at the end of the plate, forming a pre-bending effect. This process is mainly to eliminate the straight section at the end of the plate, enabling it to better fit the rolls during subsequent rolling.

  
  

• Rolling: After pre-bending is completed, the upper roll continues to descend to make the plate come into close contact with the upper and lower rolls. Then, the upper roll or the lower roll (usually the upper roll is drivable) rotates to drive the plate to roll between the three rolls. The two side rolls adjust their positions by moving horizontally to gradually curl the plate to the required radius of curvature. During the rolling process, the pressure and friction applied by the three rolls to the plate cause plastic deformation of the plate, thus achieving the rolling process.

  
  

• Shaping: As the plate is continuously rolled, the plate is gradually rolled into a cylindrical shape or other shapes. By controlling the lifting of the upper roll, the horizontal movement of the two side rolls, and the rotation of the rolls, the rolling requirements of different radii of curvature and shapes can be achieved.

  
  

• Hydraulic Unloading:

  
  

• Hydraulic System: The plate bending machine is equipped with a hydraulic system, mainly consisting of a hydraulic pump, a hydraulic cylinder, a control valve, and an oil tank, etc. The hydraulic pump provides power, sucks the hydraulic oil from the oil tank and pressurizes it, and conveys it to the hydraulic cylinder through the pipeline.

  
  

• Unloading Operation: After the plate rolling is completed, the upper roll rises to a certain height to ensure that the rolled cylinder can be unloaded smoothly. Then, start the hydraulic unloading device. The hydraulic oil enters the unloading hydraulic cylinder to drive the movement of the piston of the hydraulic cylinder. The piston rod of the hydraulic cylinder is connected to the unloading device (such as the unloading rack or unloading roll), and the movement of the piston drives the unloading device to unload the rolled cylinder from the rolls of the plate bending machine. During the unloading process, the hydraulic system can precisely control the action of the unloading device to ensure smooth and safe unloading and avoid damage to the cylinder during the unloading process.

  
  

• Reset: After unloading is completed, the hydraulic system retracts the piston of the hydraulic cylinder to make the unloading device return to its initial position, preparing for the next rolling and unloading operation.
• The mechanical symmetrical three-roll plate bending machine with a hydraulic unloading system can efficiently and accurately complete the plate rolling and unloading work and is widely used in the metal processing industry to roll various specifications of cylindrical, arc-shaped, and other workpieces.
