[0002] In industries such as sheet metal processing, automotive parts manufacturing, and sheet metal stamping, punching is a common processing method, widely used for forming various holes. Traditional punching dies typically employ manual positioning or fixed guiding structures, relying on operator experience to adjust the workpiece position. This is not only inefficient but also prone to positioning deviations leading to substandard hole accuracy, affecting product assembly quality. In recent years, with the increasing demand for automated production, automatic punching equipment has gradually become widespread, but the problem of rapid die positioning remains fundamentally unresolved. Existing technologies commonly employ positioning methods including mechanical stops, hydraulic centering mechanisms, or photoelectric sensor-assisted positioning. Fixed positioning structures are difficult to adapt to workpieces of different sizes or shapes, and die changes are time-consuming, hindering flexible production. Therefore, we have redesigned a rapid positioning mechanism for automatic punching dies. Utility Model Content
