冷冲模的突然故障和意外误冲是诱发模具事故、缩短模具寿命、甚至引起设备或人身事故造成提前中断工作的主要原因。在冲模上安装电监控装置是避免发生事故和意外误冲的有效措施。目前,冷冲模的电监控防护装置在国内尚未广泛推广使用,而在国外,尤其在联邦德国、瑞士、日本和美国,都早已在生产中普遍采用。本文结合国内冲压工作的实际需要,简要介绍冷冲模电监控装置的类型、结构、动作原理及典型实例。
Die sudden failure and accidental error is the induced mold accident, shorten the life of the mold, and even lead to equipment or personal accident caused the main reason for early interruption. Installing the electrical monitoring device on the die is an effective measure to avoid accidents and unexpected mistakes. At present, the die of the electric monitoring and control of cold die has not been widely used in China, and abroad, especially in the Federal Republic of Germany, Switzerland, Japan and the United States, have long been widely used in production. In this paper, the actual needs of the domestic stamping work, a brief introduction of the type, structure, operation principle and typical examples.
