一、HT11系列水平下调式三辊对称式卷板机性能介绍//
水平下调式三辊卷板机的上辊可作升降运动，两下辊可作单独或同时水平移动，三个工作辊均为主动辊，在卷板时无打滑现象，在特别是卷薄板时更为显着。两个下辊的的可调行程较大，在卷弯过程中，每个下辊轮流执行下辊与侧辊的功能，即先后构成两种非对称式三辊卷板机，一次装卸工件，即可完成包括前中后极端在内的全部卷弯工作。
水平下调式三辊对称式卷板机的工作原理如下：
板材定位：将待卷制的板材放置在卷板机的工作台上，通过调整进料装置或人工辅助，使板材的边缘与卷板机的辊轴对齐，确保板材在卷制过程中的位置准确。
辊轴调整：卷板机的三个辊轴呈对称分布，其中下辊轴的位置可水平调整。根据板材的厚度、宽度以及所需卷制的曲率半径等参数，通过液压系统或机械传动装置，精确地调整下辊轴的高度和水平位置，以设定合适的卷制空间和角度。
卷制过程：调整好后，启动卷板机，上辊轴在压力作用下下压，与两个下辊轴共同对板材施加压力。同时，两个下辊轴通过电机驱动进行旋转，依靠辊轴与板材之间的摩擦力带动板材移动，使其在辊轴之间逐渐弯曲变形。在卷制过程中，板材不断地被送入辊轴之间，经过多次滚压，逐渐形成所需的弧形或圆形。
曲率控制：卷板机通常配备有测量和控制系统，可实时监测板材的卷制曲率。操作人员根据测量数据，通过微调下辊轴的位置或调整上辊轴的压力，精确控制板材的弯曲程度，以达到预期的曲率要求。
端部处理：对于一些需要对板材端部进行特殊处理的情况，如预弯或端部整形，卷板机可能会配备额外的辅助装置。这些装置可以在卷制开始前或卷制过程中，对板材的端部进行单独的加工，以满足产品的工艺要求。
卸料：卷制完成后，先将上辊轴升起，解除对板材的压力，然后通过卸料装置将卷制好的工件从卷板机上取下。卸料装置可以是机械臂、输送带或其他辅助设备，以方便快捷地完成卸料操作。
I. Performance Introduction of the HT11 Series Horizontal Lower-adjustable Three-roll Symmetrical Plate Bending Machine
The upper roll of the horizontal lower-adjustable three-roll plate bending machine can move up and down, and the two lower rolls can move horizontally either separately or simultaneously. All three working rolls are driving rolls, and there is no slipping phenomenon during plate rolling, which is especially remarkable when rolling thin plates. The adjustable stroke of the two lower rolls is relatively large. During the plate bending process, each lower roll takes turns to perform the functions of the lower roll and the side roll, that is, two types of asymmetrical three-roll plate bending machines are formed successively. All bending work including the front, middle and end parts can be completed with one-time loading and unloading of the workpiece.
The working principle of the horizontal lower-adjustable three-roll symmetrical plate bending machine is as follows:
Plate Positioning: Place the plate to be rolled on the workbench of the plate bending machine. Adjust the feeding device or with the assistance of manpower to align the edge of the plate with the roller shafts of the plate bending machine, ensuring the accurate position of the plate during the rolling process.
Roller Shaft Adjustment: The three roller shafts of the plate bending machine are symmetrically distributed, and the position of the lower roller shafts can be adjusted horizontally. According to parameters such as the thickness and width of the plate and the required radius of curvature for rolling, use the hydraulic system or mechanical transmission device to precisely adjust the height and horizontal position of the lower roller shafts to set an appropriate rolling space and angle.
Rolling Process: After adjustment, start the plate bending machine. The upper roller shaft presses down under pressure and exerts pressure on the plate together with the two lower roller shafts. At the same time, the two lower roller shafts are driven by the motor to rotate, and the plate is driven to move between the roller shafts by the frictional force between the roller shafts and the plate, gradually causing the plate to bend and deform. During the rolling process, the plate is continuously fed between the roller shafts and is gradually formed into the required arc or circular shape after multiple rolling operations.
Curvature Control: The plate bending machine is usually equipped with a measurement and control system to monitor the rolling curvature of the plate in real time. Operators can precisely control the degree of bending of the plate according to the measurement data by finely adjusting the position of the lower roller shafts or adjusting the pressure of the upper roller shaft to meet the expected curvature requirements.
End Treatment: For situations where special treatment of the end of the plate is required, such as pre-bending or end shaping, the plate bending machine may be equipped with additional auxiliary devices. These devices can separately process the end of the plate before or during the rolling process to meet the technological requirements of the product.
Unloading: After the rolling is completed, first raise the upper roller shaft to release the pressure on the plate, and then use the unloading device to remove the rolled workpiece from the plate bending machine. The unloading device can be a robotic arm, conveyor belt or other auxiliary equipment to facilitate the unloading operation
