普通冲床均带有安全保护装置,按刹车方式分有手刹车、脚刹车;按刹车装置的结构分有摩擦式、转键式等。不管那种刹车装置,当操作者操作冲床进行各种冲压加工时,还会经常发生冲伤手指、断指、伤掌等不安全事故。我们采用的光电二次刹车安全装置比普通冲床的原(旧)刹车装置有更高的安全可靠性,具有结构简单、调整容易、动作灵敏、使用方便等优点。它是目前新颖的刹车安全装置,适用于100吨以下的中小型冲床。一、光电安全装置的组成 1.工作原理光电二次刹车安全装置(图1)由双路光电装置和机械装置两部分组成。其工作原理是利用冲床的工作台灯(40W以上)安置在机床左侧作光源,在机床右侧装一只可高低前后自由调节的光电接收器,使两者之
Ordinary punch presses are equipped with safety devices, according to the brake points sub-brake, foot brake; according to the structure of the brake friction points, turnkey and so on. Regardless of the type of brake device, punching fingers, broken fingers, broken fingers and other unsafe accidents often occur when an operator operates a press for various types of punching. We use the photoelectric secondary brake safety device than the ordinary punch of the old (old) brake device has higher safety and reliability, with a simple structure, easy to adjust, action-sensitive, easy to use and so on. It is currently a novel brake safety device for small and medium-sized presses up to 100 tons. First, the composition of the photoelectric safety device 1. Working principle Photoelectric secondary brake safety device (Figure 1) consists of two-way photoelectric devices and mechanical devices in two parts. Its working principle is the use of punch table lamp (40W above) placed on the left side of the machine as a light source, the right side of the machine fitted with a height before and after the free adjustment of the optical receiver so that the two
