The utility model discloses a detect atmospheric pressure output that external atmospheric pressure adjusted the cutting torch in order to adapt to the scratch start, sheet metal cutting, medium plate cutting and thick plate cutting respectively to solve single atmospheric pressure and set for low unfavorablely to cutting, and set for the too high dilemma that is difficult for the scratch start.
Description
Technical field:
This utility model relates to CUT technical field, controls inversion Plasma Are Cutting Machine particularly to a kind of many air pressure.
Background technology:
CUT is mainly used in metal, nonmetal cutting.Plasma is heated to excessive temperature and by the gas of highly ionized, and arc power is transferred on workpiece by it, and high heat makes workpiece fusing and blown off, forms slot along with the movement of plasma arc cutting torch.
At present, during the cutting of high powered plasma cutting machine, electric current is big, reaches 200～300A, so plasma gas flow requires big during cutting, but, gas flow during striking is little, if gas flow is excessive during striking, then can cause striking difficulty or can not striking.Existing CUT gas atmosphere can not change, and in order to cut certain thickness metallic plate, the air pressure often set is too high, is not suitable for striking, arcing initiation success rate 30～40%, and before cutting, repeated attempt striking affects work efficiency.
Summary of the invention:
In consideration of it, be necessary that the many air pressure designing a kind of convenient regulation burning torch air pressure control inversion Plasma Are Cutting Machine.
A kind of many air pressure control inversion Plasma Are Cutting Machine, and many air pressure control the burning torch of inversion Plasma Are Cutting Machine and include: proportioning valve, baroceptor, controller；Wherein, compressed air gas source is connected with the air inlet of proportioning valve, the gas outlet of proportioning valve is connected with cutting torch by pipeline, the detection direction of baroceptor and baroceptor it is provided with cutting torch in the same direction by cutting torch, baroceptor is electrically connected with controller, controller is also electrically connected with proportioning valve, the atmospheric pressure value near cutting torch that controller is detected by baroceptor controls the proportioning valve regulation to air pressure, and proportioning valve is provided with the most corresponding starting the arc of 4 air pressure adjustment stations, thin plate cutting, the cutting of middle plates and thick plates cutting.
Preferably, proportioning valve is specially two-position four-way solenoid valve.
Preferably, the air pressure output valve of starting the arc station is 1.8～3.3MPa.Above-mentioned air pressure output valve refers to the atmospheric pressure value at cutting torch mouth, lower same.
Preferably, the air pressure output valve of thin plate cutting work station is 3.5～4.7MPa.
Preferably, the air pressure output valve of middle plate cutting work station is 5～7.4MPa.
Preferably, the air pressure output valve of thick plates cutting station is 7.7～12MPa.
The air pressure that this utility model regulates cutting torch by detection ambient pressure exports to adapt to the starting the arc respectively, thin plate cuts, middle plate cuts and thick plates cutting, thus it is too low unfavorable to cutting to solve the setting of single air pressure, and sets the too high dilemma being difficult to the starting the arc.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of many air pressure control inversion Plasma Are Cutting Machine of a width better embodiment.In figure: proportioning valve 1, baroceptor 2, controller 3, compressed air gas source 4, pipeline 5, cutting torch 6.
Detailed description of the invention:
As it is shown in figure 1, a kind of many air pressure control inversion Plasma Are Cutting Machine, many air pressure control the burning torch of inversion Plasma Are Cutting Machine and include: proportioning valve 1, baroceptor 2, controller 3；Wherein, compressed air gas source 4 is connected with the air inlet of proportioning valve 1, the gas outlet of proportioning valve 1 is connected with cutting torch 6 by pipeline 5, it is provided with the detection direction of baroceptor 2 and baroceptor 2 with cutting torch 6 in the same direction on cutting torch 6 side, baroceptor 2 is electrically connected with controller 3, and controller 3 is also electrically connected with proportioning valve 1；The atmospheric pressure value near cutting torch 6 that controller 3 is detected by baroceptor 2 controls the proportioning valve 1 regulation to air pressure, particularly as follows: after many air pressure control the start of inversion Plasma Are Cutting Machine and during non-striking, baroceptor 2 is not detected by big atmospheric pressure value, now controller 3 controls proportioning valve 1 and is adjusted to starting the arc station, and it is automatically adjusted to thin plate cutting work station after the starting the arc, when being in plate in the cutting of thin plate cutting work station, baroceptor 2 detects that air pressure resistance is relatively big, and now controller 3 controls proportioning valve 1 and is adjusted to middle plate cutting work station；Proportioning valve 1 is provided with the most corresponding starting the arc of 4 air pressure adjustment stations, thin plate cutting, the cutting of middle plate and thick plates cutting.
In the present embodiment, proportioning valve 1 is specially two-position four-way solenoid valve.The air pressure output valve of starting the arc station is 1.8～3.3MPa.The air pressure output valve of thin plate cutting work station is 3.5～4.7MPa.The air pressure output valve of middle plate cutting work station is 5～7.4MPa.The air pressure output valve of thick plates cutting station is 7.7～12MPa.
