First, safety interval

In general, the safety interval of the safety grating refers to the shortest interval between the light curtain and the working danger area - the cutting edge of the mold, that is, the interval required to stop the slider before reaching the dangerous border from the position of the hand to block the light curtain. The safety interval is one of the necessary conditions to ensure the protection function of the safety grating, and the safety interval must be calculated correctly! The calculation method should be determined according to the braking mode of the press.

Second, the position of the safety light curtain height

The height position of the safety curtain refers to the position of the light curtain of the safety grating relative to the upper and lower die of the machine tool. Under the condition of ensuring the safety interval, the last beam of the safety grating shall not be higher than the lower edge of the die, and the last beam of the safety grating shall not be lower than the upper edge of the die.

Third, the protection height

The protection height of the safety grating refers to the interval between the top beam of the light curtain and the next beam of the light axis, that is, the effective height of the light curtain. The protection height is the stroke of the machine tool slider plus the adjustment amount. The size of the protection height is related to the number of safety grating beams. If the number of safety grating beams is too small, the height of the light curtain will not be able to completely cover the dangerous area, and there is still the possibility of causing accidents. If it is too large, it will cause a waste of funds and inconvenience in use. Therefore, it is also very important to select the safety grating specification (beam number) according to the protection height.
