扭轴数控折弯机的工作原理如下：
动力与传动：扭轴数控折弯机通常由电机提供动力，通过液压系统或机械传动装置将动力传递到各个工作部件。在液压传动的扭轴数控折弯机中，电机驱动油泵，将液压油加压并输送到各个液压缸，通过液压缸的伸缩来实现滑块的上下运动以及其他辅助动作。而在一些采用机械传动的折弯机中，电机通过皮带、齿轮或丝杠等传动机构带动滑块运动。
扭轴同步原理：扭轴数控折弯机的关键在于扭轴同步机构。扭轴是一根贯穿于折弯机两侧的轴，当滑块进行折弯动作时，扭轴会发生扭转。扭轴的扭转角度与滑块的行程以及折弯力之间存在着一定的比例关系。通过精确控制扭轴的扭转，可以实现两侧滑块的同步运动，保证折弯精度。具体来说，当一侧滑块受到的阻力较大时，扭轴会将扭矩传递到另一侧滑块，使得两侧滑块能够保持同步，避免出现折弯角度不一致或板材扭曲等问题。
数控系统控制：数控系统是扭轴数控折弯机的大脑，操作人员通过数控系统输入折弯参数，如折弯角度、长度、速度等。数控系统根据这些参数计算出滑块的运动轨迹和扭轴的扭转角度，并向各个执行部件发送控制信号。在折弯过程中，数控系统会实时监测滑块的位置和扭轴的状态，通过反馈机制不断调整控制信号，以确保实际折弯过程与预设参数相符。例如，如果发现滑块的运动速度偏离了预设值，数控系统会自动调整液压流量或电机转速，使滑块回到正确的运动轨迹上。
模具作用：模具是扭轴数控折弯机实现板材折弯的直接工具。上模和下模分别安装在滑块和工作台上，当滑块下行时，上模与下模闭合，对置于其间的板材施加压力，使板材发生塑性变形，从而实现折弯。不同的折弯形状和尺寸需要使用相应的模具，通过更换模具，可以满足各种不同的折弯工艺要求。
Working Principle of the Torsion Shaft CNC Bending Machine
The working principle of the torsion shaft CNC bending machine is as follows:
Power and Transmission: The torsion shaft CNC bending machine is usually powered by an electric motor, and the power is transmitted to each working component through a hydraulic system or a mechanical transmission device. In a torsion shaft CNC bending machine with hydraulic transmission, the electric motor drives an oil pump to pressurize the hydraulic oil and deliver it to each hydraulic cylinder. The expansion and contraction of the hydraulic cylinders are used to achieve the up-and-down movement of the slider and other auxiliary actions. In some bending machines using mechanical transmission, the electric motor drives the slider to move through transmission mechanisms such as belts, gears or lead screws.
Principle of Torsion Shaft Synchronization: The key of the torsion shaft CNC bending machine lies in the torsion shaft synchronization mechanism. The torsion shaft is a shaft running through both sides of the bending machine. When the slider performs the bending action, the torsion shaft will twist. There is a certain proportional relationship between the torsion angle of the torsion shaft, the stroke of the slider and the bending force. By precisely controlling the torsion of the torsion shaft, the synchronous movement of the sliders on both sides can be achieved, ensuring the bending accuracy. Specifically, when the resistance on one side of the slider is relatively large, the torsion shaft will transmit the torque to the slider on the other side, enabling the sliders on both sides to remain synchronized and avoiding problems such as inconsistent bending angles or sheet metal distortion.
Control of the CNC System: The CNC system is the brain of the torsion shaft CNC bending machine. The operator inputs bending parameters such as the bending angle, length, and speed through the CNC system. The CNC system calculates the movement trajectory of the slider and the torsion angle of the torsion shaft according to these parameters, and sends control signals to each executing component. During the bending process, the CNC system will monitor the position of the slider and the status of the torsion shaft in real time, and continuously adjust the control signals through the feedback mechanism to ensure that the actual bending process conforms to the preset parameters. For example, if it is found that the movement speed of the slider deviates from the preset value, the CNC system will automatically adjust the hydraulic flow or the rotational speed of the motor to make the slider return to the correct movement trajectory.
Function of the Dies: The dies are the direct tools for the torsion shaft CNC bending machine to achieve sheet metal bending. The upper die and the lower die are respectively installed on the slider and the worktable. When the slider moves downward, the upper die and the lower die close, applying pressure to the sheet metal placed between them, causing the sheet metal to undergo plastic deformation, thus achieving bending. Different bending shapes and sizes require corresponding dies. By replacing the dies, various different bending process requirements can be met.
