冲模的突然故障和意外误冲是引起模具事故、缩短模具寿命、造成提前中断工作的主要原因。根据模具结构的不同,在其容易发生故障和损坏的位置,特别是细小的冲孔凸模、薄弱的弯曲凸模及拉伸凸模、弹顶器、卸件器、送科装置、冲压半成品及单个块料送进等,安装简易电控防护装置,避免发生意外误冲和故障。本文结合国内实际需要,重点论述使用简易电控冲模防护装置的原理并介绍国外已纳入有关技术规范的典型实例,供参考。 Sudden failure of the die and accidental accidents are the main causes of die accidents, shortening die life, and causing premature interruptions. According to the different mold structure, in the place where it is prone to failure and damage, especially small punch punches, weak curved punches and stretch punches, dome ejectors, unloaders, delivery devices, stamping semi-finished products and individual Block feeding, etc., install a simple electronic control device to prevent accidental accidents and failures. This article combines the actual needs of the country, focusing on the use of simple electronic control die protection device principle and introduces the typical examples of foreign countries have been included in the relevant technical specifications for reference.
