卷板机是一种利用工作辊对钣金进行弯曲成型的设备。它可以形成不同形状的零件，如圆柱形零件和锥形零件。对于加工设备是非常重要的。折板机的工作原理是在液压、机械力等外力的作用下，使工作辊运动，使板材弯曲或轧制成型。根据不同形状工作辊的转动运动和位置变化，可加工椭圆件、圆弧件、圆柱件等零件。
卷板机的种类
由于使用领域的不同，弯板机也有所不同。
它分为a
三辊轧制机和
四辊轧机
从滚轮的数量．三辊分为对称式三辊卷板机、卧式下调三辊卷板机、弧形下调三辊卷板机、上辊万能三辊卷板机、液压数控卷板机。
从传输，分为机械式和液压式。就卷板机的发展而言，上辊式万向型最落后，水平向下调节略先进，圆弧向下调节最先进。
安全运行
一般来说，机械设备的运行效率和故障率与操作人员有非常密切的关系。作为危险设备的操作人员，应多学习相关知识，以有效避免操作人员误操作或造成事故。事故发生了。让我们来了解一下滚轧机操作的细节和安全要求。
首先是操作人员在操作前要整理好工作环境，保持良好的操作环境。同时，操作人员必须衣着整洁，避免在操作过程中把衣服的边角弄进卷里。在加工过程中，必须注意的是，操作人员只能站在工件两侧是一个合理的位置。如果要在操作过程中调整测量圆度，必须在操作过程中停止操作，禁止操作。当加工后的零件到达时，应留有一定的余量。
在测量尺寸圆度的过程中，禁止操作人员站在轧制圆筒上，禁止站在待加工工件上。对于一些难度较大的工件:如较厚、直径较大、原材料硬度或强度较高等，应同时做少量的工作，以达到预期的效果。对于一些直径较小的工件，应在轧辊中间进行轧制操作。
维护程序
1. According to the provisions of the machine lubrication diagram, lubricate the lubrication points of each oil cup and manual lubrication points as required.
2. Roll the plate according to the parameters specified by the plate bending machine, the thickness of the plate is 20mm, the length is 2500mm, and the yield limit of the plate material is less than 250Mpa.
3. After turning on the power, carry out the movement of the lower roller in both positive and negative directions and the upper roller’s lifting movement, and check whether each movement is abnormally stuck.
4. Strictly operate in accordance with the coil processing procedures and operating methods. When the upper roller is raised to the limit position, pay great attention to the safe operation of the equipment.
5. When the main drive is stopped, the upper roller can be raised and lowered, the tilting reset of the overturned bearing and the upper roller can be lifted.
6. During operation, if irregular noise, impact, etc. are found, stop the machine for inspection immediately.
7. All personnel must coordinate with each other during the operation and follow the instructions of the person in charge of the coil. Without a password, it is forbidden to start the machine.
8. When carrying out the plate rolling operation, pay great attention to the hand being pressed by the steel plate and the steel plate is rolled together.
9. When lifting the steel plate or drum with a crane, be careful not to collide with the machine. After the coiling is completed, the finished materials should be cleaned up, and the equipment should be maintained and the power supply should be turned off in time.
