• 动力传递：数控摆式剪板机通常由电机提供动力，通过皮带、齿轮或联轴器等传动装置将动力传递给液压系统或机械传动机构。液压系统将机械能转化为液压能，通过液压油的压力驱动液压缸运动；机械传动机构则直接将电机的旋转运动转化为刀片的摆动运动。

• 刀片摆动：上刀片安装在一个可摆动的刀架上，刀架通过销轴与机体相连，形成一个摆动副。当液压缸或机械传动机构驱动刀架时，上刀片绕着销轴做摆动运动。下刀片固定在工作台上，与上刀片相对布置。在剪切过程中，上刀片与下刀片之间形成一个楔形的剪切区域。

• 板材定位与夹紧：在剪切之前，需要将待剪切的板材放置在工作台上，并通过定位装置进行精确定位。定位装置通常包括挡料板、定位销等，可根据板材的尺寸和剪切要求进行调整。然后，通过夹紧装置将板材固定在工作台上，防止在剪切过程中板材发生移动或晃动。夹紧装置一般采用液压或机械夹紧方式，能够提供足够的夹紧力，保证剪切精度。

• 剪切过程：当板材定位和夹紧完成后，控制系统发出指令，驱动上刀片向下摆动，与下刀片闭合，对板材进行剪切。在剪切过程中，上刀片的刃口与板材表面接触，产生剪切力，使板材沿着剪切线分离。由于上刀片的摆动运动，刀片与板材之间的摩擦力较小，能够减少板材的变形和损伤。同时，摆式结构使得刀片在剪切时的受力较为均匀，有利于提高刀片的使用寿命。

• 间隙调整：数控摆式剪板机具有自动间隙调整功能，能够根据板材的厚度和材质自动调整上刀片与下刀片之间的间隙。这是通过安装在刀架上的间隙调整机构实现的。在剪切不同厚度的板材时，控制系统会根据预设的参数自动调整间隙，以保证剪切质量。合适的刀片间隙可以使剪切力均匀分布在刀片刃口上，避免因间隙过大或过小导致的剪切面不平整、毛刺过大等问题

• Power Transmission: A CNC pendulum shearing machine is usually powered by an electric motor. The power is transmitted to the hydraulic system or the mechanical transmission mechanism through transmission devices such as belts, gears, or couplings. The hydraulic system converts mechanical energy into hydraulic energy and drives the hydraulic cylinder to move through the pressure of the hydraulic oil. The mechanical transmission mechanism directly converts the rotational motion of the electric motor into the swinging motion of the blades.
• Blade Swinging: The upper blade is installed on a swingable tool holder, and the tool holder is connected to the machine body through a pin shaft to form a swinging pair. When the hydraulic cylinder or the mechanical transmission mechanism drives the tool holder, the upper blade swings around the pin shaft. The lower blade is fixed on the worktable and is arranged opposite to the upper blade. During the shearing process, a wedge-shaped shearing area is formed between the upper and lower blades.
• Sheet Metal Positioning and Clamping: Before shearing, the sheet metal to be sheared needs to be placed on the worktable and accurately positioned through the positioning device. The positioning device usually includes a backgauge, positioning pins, etc., which can be adjusted according to the size of the sheet metal and the shearing requirements. Then, the sheet metal is fixed on the worktable by the clamping device to prevent it from moving or shaking during the shearing process. The clamping device generally adopts a hydraulic or mechanical clamping method, which can provide sufficient clamping force to ensure the shearing accuracy.
• Shearing Process: After the sheet metal is positioned and clamped, the control system issues an instruction to drive the upper blade to swing downward and close with the lower blade to shear the sheet metal. During the shearing process, the cutting edge of the upper blade contacts the surface of the sheet metal, generating a shearing force that separates the sheet metal along the shearing line. Due to the swinging motion of the upper blade, the friction between the blade and the sheet metal is relatively small, which can reduce the deformation and damage of the sheet metal. At the same time, the pendulum structure makes the force on the blade more evenly distributed during shearing, which is beneficial to improving the service life of the blade.
• Clearance Adjustment: A CNC pendulum shearing machine has an automatic clearance adjustment function, which can automatically adjust the clearance between the upper and lower blades according to the thickness and material of the sheet metal. This is achieved through the clearance adjustment mechanism installed on the tool holder. When shearing sheet metal of different thicknesses, the control system will automatically adjust the clearance according to the preset parameters to ensure the shearing quality. An appropriate blade clearance can make the shearing force evenly distributed on the cutting edge of the blade, avoiding problems such as an uneven shearing surface and excessive burrs caused by an excessively large or small clearance
