无飞边和减小飞边锻造,正愈益成为节约金属和提高产品质量的有效工艺。它能够提供设计研究和一般的工业咨询,并已经广泛地调查和研究了圆形零件,还正在研究细长和中空零件。作者设计了如下所述的装有液压过载保护装置的模具,并且制造了用于机械压力机的完全闭式锻模。该模具是自容式的,轻便而且可装在任何标准机器上。图1示出了模具装置的略图,并从功能观点可将其分为三个部分:1.固定在滑块上的上模和压圈;2.凹模镶块和压 No flash and reduce the flash forging, is increasingly becoming an effective process to save the metal and improve product quality. It can provide design research and general industrial consulting, and has extensively investigated and studied round parts, and is also working on slender and hollow parts. The author devised a mold equipped with a hydraulic overload protection device as described below and manufactured a fully closed die for a mechanical press. The mold is self-contained, lightweight and can be mounted on any standard machine. Figure 1 shows a schematic view of the mold assembly, and from the functional point of view can be divided into three parts: 1. Fixed on the slider on the mold and pressure ring; 2. Die insert and pressure
