在冲压生产中,操作错误、条料重迭、冲料材质不均、条料过宽过窄以及一些零件导向不良或者由于冲床振动而引起的一些零件位移都会产生突然的过载,往往使小型凸模损坏,而造成废品、停工和增加工装成本。为此要设置过载保护的安全装置。 有各种类型的安全装置,例如电子故障检测仪、液压、机械、电动、气动安全装置等。本文介绍机械式的安全装置。 机械式安全装置可以分为两种型式:1.非更换型:弹簧和位移式;2.更换型:安全
In the stamping production, the operation error, the strip overlap, the uneven material, the material is too narrow and too narrow strip, and some parts are poorly oriented or due to punch vibration caused by some of the parts will have a sudden overload displacement, often make small convex Die damage, resulting in waste, downtime and increase tooling costs. To do this, set up an overload protection safety device. There are various types of safety devices such as electronic fault detectors, hydraulic, mechanical, electric, pneumatic safety devices and the like. This article describes a mechanical safety device. Mechanical safety devices can be divided into two types: 1. Non-replacement type: spring and displacement; 2. Replacement type: safety
