The theoretical safety suction means that under the condition that the vacuum sucker does not age and harden, Vacuum sucker There is no damage or crack, the surface of the vacuum sucker is clean, the surface quality of the plate is good, and the lip of the vacuum sucker fits the surface of the plate better. In the case of less air leakage, the vacuum degree can reach more than 60%. Ruohao vacuum sucker: how to ensure the safe use of vacuum sucker?

Therefore, in order to ensure the safe use of the vacuum sucker system, please pay attention to:

(1) Make sure to regularly clean and inspect the lip surface of the vacuum suction cup (the side attached to the plate), and regularly check the vacuum suction cup for scratches, cracks and aging. If yes, replace the vacuum sucker immediately. I have seen that the vacuum sucker used by many enterprises is unsafe, which makes people worry about safety accidents.

(2) When the steel plate surface is rusty and uneven, the safety factor should be amplified, otherwise it may not be well absorbed. In view of this situation, Qi Ren innovatively designed a set of fast hook system (rhombic hook), which is symmetrically integrated at both ends of the beam and is applicable to the following two situations:

-During the feeding process, the power is cut off suddenly, and the steel plate will not fall off when the diamond hook is used. When calling again.

-When the steel plate is rusty or more than 10mm, use a vacuum sucker to lift it a little, and then wear a diamond hook to ensure safety and security.

Influence of vacuum power supply on vacuum pressure:

Vacuum sucker feeding is a manual auxiliary feeding mode, which is necessary to ensure the safety of personnel.

The vacuum degree of the vacuum generator is lower than that of the vacuum pump, so it is safer to use the vacuum pump as the vacuum power supply. Professional gas supply system companies do not use vacuum generators, which is also a factor. Due to the requirements for high-pressure gas, some factories are short of gas sources and the gas pipe layout is inconvenient.

There are also two kinds of vacuum pumps, one is three-phase power, which needs to be connected from the workshop electrical box to the control box of the vacuum sucker system.

One is to use weak current vacuum pump as vacuum power supply. If the customer drives too high on the spot and it is inconvenient to get power, please use this pump, use 12V battery to supply power, and charge regularly.

Requirements for sheet metal overhang of vacuum suction cup system:

The overhang is the distance between the edge of the plate and the edge of the nearest vacuum cup. The tape metric shown in the following figure is the amount of drape.

When the overhang is large, the plate sags seriously and the vacuum sucker cannot absorb. 1mm piece, safety suspension 500 mm. Considering the problem of overhang, the length of main beam, the number of vacuum cups and the distance between vacuum cups must be specially designed for steel plates of different sizes.

The specific application of vacuum sucker system in the feeding of laser cutting machine actually has many important indicators that deserve attention, not only vacuum sucker is such a simple thing# P # Page Title # e#
