在使用气动装置时,必须要有一定的防护装置,以保护机床设备、操作人员的安全。特别是操作人员在工作时需要与冲锤以及其它成形装置相接触时,这种防护装置就更重要。例如,在冲床加工中,应保证人手离开冲位后冲模才下来,下面介绍几个常用的气动装置安全回路。1.当压力降低时防护人员及设备的安全回路图1所示的回路能用于当压力降低至工作安全的范围以下时,保护操作人员及设备的安全。当回路的气源压力是在正常的工作范围内时,阀1
In the use of pneumatic devices, there must be some protection to protect machine equipment, operator safety. This type of guard is even more important when the operator needs to be in contact with the ram and other forming devices at work. For example, in the process of punching, it should be ensured that the die will be removed after leaving the punching position. Here are some commonly used pneumatic safety circuits. 1. Safety circuit for guards and equipment when pressure is reduced The circuit shown in Figure 1 can be used to protect the safety of operators and equipment when the pressure falls below the working safety range. Valve 1 is used when the air pressure in the circuit is within the normal operating range
