Positive pressure is often less than cutting air pressure, in practical operation, for different types of plate, cutting auxiliary gas can carry out oxygen, nitrogen,
The switching of air.Oxygen or air perforations, oxygen machining can be adopted as cut during carbon plate；Nitrogen can be adopted during cutting stainless steel plate
Or the cutting of air perforations, nitrogen.The different perforation switching of cutting auxiliary gas, can affect work efficiency.For this reason, we are to existing
Some cutting torch are optimized, there is provided a kind of two-way parallel connection air perforations solve above-mentioned technological deficiency with compound cutting torch.
Utility model content
The purpose of this utility model is to provide a kind of two-way parallel connection air perforations with compound cutting torch, to solve above-mentioned background
The problem proposing in technology.
For achieving the above object, this utility model provides following technical scheme：A kind of two-way parallel connection air perforations are with being combined
Cutting torch, including cutting torch body, described cutting torch chamber body middle position has cutting torch composite bed, two about described cutting torch composite bed
Side is arranged with peripheral accessory channel, and described cutting torch chamber body is provided with mixing chamber, and described cutting torch composite bed and periphery assist
The outlet side of passage is all communicated in mixing chamber, and at described cutting torch body edges, inner chamber has air perforations passage, described sky
Gas perforation passage top has perforation air intake, and described cutting torch chamber body bottom is provided with main injection jet, described air perforations
All connected with main injection jet with mixing chamber with passage.
Preferably, described air perforations are no less than 3 groups with passage, and air perforations passage is structure wide at the top and narrow at the bottom.
Preferably, the multiple difference of described air perforations passage upper channel and lower channel internal diameter is 1.2 times, and air perforations
With passage around main injection jet ringwise radial arrangement.
Preferably, described cutting torch composite bed is internal layer pyramidal structure, and described periphery accessory channel around cutting torch composite bed is in
Centrosymmetry arranges.
Preferably, described cutting torch body is made up of parallel lumens and conical internal cavity.
Compared with prior art, the beneficial effects of the utility model are：This two-way parallel connection air perforations, with compound cutting torch, are cut
After cutting auxiliary gas entrance cutting torch, a part is blown out by composite bed inner chamber, and another part is blown out by composite bed outer layer channel,
Finally unify by the main injection jet blowout of cutting torch body, the quality of compound cutting torch centering thick plates cutting section has greatly improved,
Increase cannelure and at least 3 tunnel air perforations passages on cutting torch body, so can no dead angle it be blown, air perforations
It is designed as upper-wide and lower-narrow type structure with passage, by increasing capacitance it is possible to increase air velocity, be easy to blow away welding slag.
Brief description
Fig. 1 is this utility model structural representation.
In figure：1 cutting torch body, 2 cutting torch composite beds, 3 peripheral accessory channels, 4 air perforations passages, 5 perforation air enter
Mouth, 6 main injection jets, 7 mixing chamber.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme：A kind of two-way compound cutting torch of parallel connection air perforations,
Including cutting torch body 1, described cutting torch body 1 inner chamber middle position has cutting torch composite bed 2, described cutting torch composite bed 2 about two
Side is arranged with peripheral accessory channel 3, and described cutting torch body 1 inner chamber is provided with mixing chamber 7, described cutting torch composite bed 2 and periphery
The outlet side of accessory channel 3 is all communicated in mixing chamber 7, and described cutting torch body 1 edge's inner chamber has air perforations passage
4, described air perforations passage 4 top has perforation air intake 5, and described cutting torch body 1 intracavity bottom is provided with main injection jet 6,
Described air perforations passage 4 is all connected with main injection jet 6 with mixing chamber 7.
Wherein, described air perforations are no less than 3 groups with passage 4, and air perforations passage 4 is structure wide at the top and narrow at the bottom, institute
State air perforations passage 4 upper channel and the multiple difference of lower channel internal diameter is 1.2 times, and air perforations passage 4 is around main jet
Mouth 6 ringwise radial arrangement, described cutting torch composite bed 2 is internal layer pyramidal structure, and described periphery accessory channel 3 is multiple around cutting torch
Close layer 2 to be centrosymmetric arrangement, described cutting torch body 1 is made up of parallel lumens and conical internal cavity.
Specifically, during use, after cutting auxiliary gas enters cutting torch, a part is blown out by cutting torch composite bed 2 inner chamber, separately
A part is blown out by peripheral accessory channel 3, and finally unification is blown out by the main injection jet 6 of cutting torch body 1, and compound cutting torch is to cut deal
The quality of cutting section has greatly improved, and increases cannelure and at least 3 tunnel air perforations passages 4 on cutting torch body 1, this
