二、数控四辊卷板机的工作原理是通过数控系统控制四个辊子的运动，对板材进行弯曲卷制，具体如下：
结构组成：数控四辊卷板机主要由上辊、下辊、侧辊和数控系统等组成。上辊位于设备的上部，是卷制板材的主要执行部件；下辊位于上辊下方，起到支撑板材和辅助卷制的作用；两个侧辊对称分布在上辊和下辊两侧，用于控制板材的边缘位置和调整卷制曲率。
板材送料：将待卷制的板材放置在卷板机的工作台上，通过输送装置将板材送入卷板机的辊子之间。在送料过程中，板材的位置和姿态由数控系统进行精确控制，确保板材能够准确地进入卷制区域。
辊子运动控制：数控系统根据预先设定的卷制参数（如弯曲半径、卷制角度等），分别控制上辊、下辊和侧辊的运动。上辊和下辊通过电机驱动进行旋转，提供卷制板材所需的摩擦力和驱动力，使板材在辊子的作用下逐渐弯曲。侧辊则通过液压或丝杠传动机构进行水平移动，调整板材两侧的受力情况，从而控制板材的卷制曲率和形状。在卷制过程中，数控系统实时监测辊子的位置、速度和扭矩等参数，并根据实际情况进行自动调整，以保证卷制精度和质量。
卷制过程：随着辊子的转动和侧辊的移动，板材在三个辊子的共同作用下逐渐被弯曲成所需的形状。在卷制初始阶段，上辊和下辊对板材施加压力，使板材产生初步的弯曲；然后，侧辊逐渐向内移动，进一步调整板材的弯曲程度，直到达到设定的卷制半径和角度。在整个卷制过程中，板材始终受到辊子的均匀压力和摩擦力，从而保证了卷制的精度和表面质量。
板材成型：当板材卷制到预定的形状和尺寸后，卷板机停止工作，上辊升起，取出卷制好的工件。如果需要对工件进行进一步的加工或调整，数控四辊卷板机还可以进行多次卷制或微调操作，以满足不同的工艺要求。
辊子结构与作用：数控四辊卷板机主要由上辊、下辊和两个侧辊组成。上辊位于设备的上部，是卷制过程中的主要施压辊，它可以在垂直方向上进行升降运动，以调整对板材的压力。下辊位于设备的底部，主要用于支撑板材，并与上辊配合形成对板材的初步弯曲。两个侧辊则分布在板材的两侧，它们可以在水平方向上进行移动，通过调整侧辊的位置，能够控制板材的弯曲半径和形状。
板材送料：将待卷制的板材放置在卷板机的工作台上，通过上料装置将板材输送到指定位置。在送料过程中，板材的边缘需要与卷板机的辊子保持平行，以确保卷制的精度。
预弯阶段：板材送料到位后，上辊下降，与下辊一起对板材的两端进行预弯。预弯的目的是使板材的两端形成一定的弧度，以便后续的卷制过程能够顺利进行。在预弯过程中，数控系统会根据预先设定的参数，精确控制上辊的下降速度和压力，以保证预弯的角度和半径符合要求。
卷制阶段：预弯完成后，两个侧辊开始向内侧移动，同时上辊继续施加压力，使板材在三个辊子的共同作用下逐渐弯曲成所需的形状。在卷制过程中，数控系统会实时监测板材的弯曲情况，并根据反馈信号自动调整侧辊的移动速度和上辊的压力，以确保卷制的精度和质量。当板材卷制到一定程度后，需要将板材的末端与起始端进行对接，形成一个完整的圆筒或其他形状的工件。此时，需要精确控制板材的位置和卷制的角度，以保证对接的精度。
校圆阶段：卷制完成后，为了提高工件的圆度和精度，需要对卷制后的工件进行校圆。校圆过程中，上辊和侧辊会对工件进行轻微的调整和施压，使工件的圆周度更加均匀，消除可能存在的局部变形和不圆度。
总之，数控四辊卷板机通过数控系统对四个辊子的精确控制，实现了对板材的高精度卷制。这种工作原理使得卷板机能够适应各种不同材质、厚度和宽度的板材卷制需求，广泛应用于机械制造、石油化工、电力、船舶制造等多个行业
What is the working principle of the numerically controlled four-roller plate bending machine?
The working principle of the numerically controlled four-roller plate bending machine is to control the movement of the four rollers through the numerical control system to bend and roll the plate. The details are as follows:
Structural composition: The numerically controlled four-roller plate bending machine is mainly composed of the upper roller, lower roller, side rollers, and the numerical control system. The upper roller is located at the upper part of the equipment and is the main executive component for rolling the plate. The lower roller is located below the upper roller, which plays a role in supporting the plate and assisting in rolling. The two side rollers are symmetrically distributed on both sides of the upper and lower rollers and are used to control the edge position of the plate and adjust the rolling curvature.
Plate feeding: Place the plate to be rolled on the workbench of the plate bending machine, and feed the plate between the rollers of the plate bending machine through the conveying device. During the feeding process, the position and posture of the plate are precisely controlled by the numerical control system to ensure that the plate can accurately enter the rolling area.
Roller movement control: The numerical control system controls the movement of the upper roller, lower roller, and side rollers respectively according to the preset rolling parameters (such as bending radius, rolling angle, etc.). The upper and lower rollers are driven by a motor to rotate, providing the friction force and driving force required for rolling the plate, so that the plate is gradually bent under the action of the rollers. The side rollers move horizontally through the hydraulic or screw drive mechanism to adjust the force on both sides of the plate, thereby controlling the rolling curvature and shape of the plate. During the rolling process, the numerical control system monitors parameters such as the position, speed, and torque of the rollers in real time and makes automatic adjustments according to the actual situation to ensure the rolling accuracy and quality.
Plate forming: As the rollers rotate and the side rollers move, the plate is gradually bent into the required shape under the combined action of the three rollers. In the initial stage of rolling, the upper and lower rollers apply pressure to the plate to produce a preliminary bend. Then, the side rollers gradually move inward to further adjust the degree of bending of the plate until the set rolling radius and angle are reached. Throughout the rolling process, the plate is uniformly pressured and frictioned by the rollers, ensuring the accuracy of rolling and the surface quality.
When the plate is rolled to the predetermined shape and size, the plate bending machine stops working, the upper roller rises, and the rolled workpiece is taken out. If further processing or adjustment of the workpiece is required, the numerically controlled four-roller plate bending machine can also perform multiple rolling or fine-tuning operations to meet different process requirements.
Roller Structure and Function: The numerically controlled four-roller plate bending machine is mainly composed of an upper roller, a lower roller, and two side rollers. The upper roller is located at the upper part of the equipment and serves as the main pressure-applying roller during the rolling process. It can move up and down vertically to adjust the pressure on the plate. The lower roller is located at the bottom of the equipment and is mainly used to support the plate. It cooperates with the upper roller to form the preliminary bending of the plate. The two side rollers are distributed on both sides of the plate and can move horizontally. By adjusting the position of the side rollers, the bending radius and shape of the plate can be controlled.
Plate Feeding: Place the plate to be rolled on the workbench of the plate bending machine, and use the feeding device to convey the plate to the designated position. During the feeding process, the edge of the plate needs to be kept parallel to the rollers of the plate bending machine to ensure the rolling accuracy.Pre-bending Stage: After the plate is fed in place, the upper roller descends and pre-bends both ends of the plate together with the lower roller. The purpose of pre-bending is to form a certain curvature at both ends of the plate so that the subsequent rolling process can proceed smoothly. During the pre-bending process, the numerical control system precisely controls the descending speed and pressure of the upper roller according to the preset parameters to ensure that the pre-bending angle and radius meet the requirements.
Rolling Stage: After the pre-bending is completed, the two side rollers start to move inward, and at the same time, the upper roller continues to apply pressure, so that the plate is gradually bent into the required shape under the combined action of the three rollers. During the rolling process, the numerical control system monitors the bending situation of the plate in real time and automatically adjusts the moving speed of the side rollers and the pressure of the upper roller according to the feedback signals to ensure the rolling accuracy and quality. When the plate is rolled to a certain extent, the end of the plate needs to be docked with the starting end to form a complete cylindrical or other shaped workpiece. At this time, the position of the plate and the rolling angle need to be precisely controlled to ensure the docking accuracy.
Circularity Correction Stage: After the rolling is completed, in order to improve the roundness and accuracy of the workpiece, the rolled workpiece needs to be corrected for circularity. During the circularity correction process, the upper roller and the side rollers slightly adjust and apply pressure to the workpiece to make the circularity of the workpiece more uniform and eliminate possible local deformation and out-of-roundness.
In conclusion, the numerically controlled four-roller plate bending machine achieves high-precision rolling of plates through the precise control of the four rollers by the numerical control system. This working principle enables the plate bending machine to meet the rolling requirements of plates of various materials, thicknesses, and widths, and it is widely used in many industries such as mechanical manufacturing, petrochemical, electric power, and shipbuilding
