工作原理
YWH21-200T 开式 C 型液压冲床以液压传动为核心，通过电机带动液压泵产生高压油，经控制阀组进入主油缸，推动滑块向下运动，实现冲压、压装、成型等动作。系统可对压力、速度、行程进行精准调节，配合电控系统完成快下、工进、保压、回程等循环。设备依靠液压油传递动力，动作平稳、冲击小，在保压与慢速成型工况下优势明显，既能保证加工精度，又能保护模具与工件，满足多种冲压工艺要求。 技术参数
YWH21-200T 开式 C 型液压冲床公称压力为 2000kN，额定液压 25MPa，滑块行程范围可根据工艺需求定制，开口高度同样支持按需选配。工作台面配备标准 T 型槽，方便模具快速装夹固定。设备主电机功率合理配置，动力输出稳定，运行噪音较低。滑块具备空行程快速下降、工作行程平稳压制以及快速回程的动作特性，可实现定压、定程、保压等多种工作模式。整机外形尺寸紧凑，占地面积小，安装地基要求简单，整机重量适中，结构刚性充足，可满足长时间连续冲压作业的使用要求。 选型原则
根据工件所需最大成型压力选择，确保压制力留有安全余量，避免长期满负荷运行。
依据工件尺寸与模具大小，确认工作台面、开口高度、滑块行程满足安装与加工空间需求。
结合工艺类型选型，冲孔、落料、压装、校正、浅拉伸等不同工序，对应调整速度与压力控制模式。
按照生产批量与自动化程度选择控制方式，小批量多用手动调整，大批量生产优先选配自动循环模式。
结合车间场地、电源条件与地基情况，确定设备外形尺寸与安装方式，保证后期使用与维护便捷。
综合预算与长期使用成本，优先选择适配自身行业的配置，兼顾稳定性、能耗与维护成本。
