ZuoLong machinery: teach you two ways of cutting holes

With no stamping device cutting machine has two kinds of the basic ways of perforation:

1) Pulse perforation: the peak value of pulse power make a small amount of material to melt or vaporize, commonly used as auxiliary air or nitrogen gas, to reduce the make hole expansion with exothermic oxidation, gas pressure is cutting the oxygen pressure is small. Produce only small particles of each pulse injection, and gradually in-depth, so thick plate punch time takes a few seconds. Once the perforated completion, auxiliary gas into oxygen cutting. This perforation diameter smaller, the perforation quality is better than that of blasting hole. The apparatus for use not only should have high output power; Even more important when time and space characteristics of the light beam, therefore generally transverse CO2 can not adapt to the requirements of the cutting. Pulse perforation also need to have a reliable pneumatic control system, in order to realize the gas species, cutting machine, gas pressure switch and perforation of time control. In the case of using pulse perforation, in order to obtain high quality of incision, from workpiece resting pulse perforation to the transition of workpiece speed continuous cutting technology should take seriously.

2) Blasting perforation: material after the illuminate of continuous formed in the center of a pit, and then with bunch of coaxial oxygen flow quickly remove the molten material into a hole. General hole size and thickness, half of the average diameter to thickness, blasting perforation for thicker plate blasting perforation aperture is bigger, and do not round, unfavorable use (on demand higher parts Such as oil sieve tube) And can only be used for waste. In addition due to perforation of oxygen to the same pressure and cutting, splash is bigger.





cutting perforation technology: any kind of thermal cutting technology, except a few cases can start on the plate edge, generally must be a small hole on the plate. Earlier in the compound stamping machine is with a hole punch rushed out of the first, and then with a start from the small hole cutting.

in theory usually change accelerating period of cutting conditions: such as focal length, position of nozzle, gas pressure, but in fact, due to the time is too short to change the above conditions is unlikely. Mainly used in industrial production change the average power method is more realistic, concrete method has the following three kinds:

( 1) Change the pulse frequency;

( 2) Change the pulse width and frequency at the same time.

( 3) Change the pulse width;

through the interpretation of the above you with perforation technology, good cutting machine perforation technology difference is very big, so it is very important to choose a good cutting machine, ZuoLong mechanical cutting machine makes the cutting processing equipment, is not something you choose.
