Background technology
Cutting torch is a kind of nozzle of flame cutting torch for metallurgical works, and it is logical by preheating oxygen, combustion gas and cutting oxygen three
Road forms, cutting torch divides normal cutting and perforation procedure two parts at cutting process, existing cutting torch cutting carbon plate, stainless steel-like
Thin plate (below 5mm) is less problematic；Cutting slab, cutting section can cause Quality Down, perforation procedure gas due to air-flow shakiness
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.As oxygen or air perforations, oxygen machining can be used when cutting carbon plate；Nitrogen can be used during cutting stainless steel plate
Or the cutting of air perforations, nitrogen.The different perforation switching of cutting auxiliary gas, can affect work efficiency.To this end, we are to existing
Some cutting torch are optimized, it is provided that a kind of two-way parallel connection air perforations solves above-mentioned technological deficiency with compound cutting torch.
Summary of the invention
It is an object of the invention to provide the compound cutting torch of a kind of two-way parallel connection air perforations, to solve above-mentioned background technology
The problem of middle proposition.
For achieving the above object, the present invention provides following technical scheme: a kind of two-way parallel connection air perforations is used and is combined cutting torch,
Including cutting torch body, described cutting torch chamber body middle position has cutting torch composite bed, the described cutting torch composite bed left and right sides pair
Claiming to be provided with peripheral accessory channel, described cutting torch chamber body is provided with mixing chamber, described cutting torch composite bed and peripheral accessory channel
Outlet side be all communicated in mixing chamber, at described cutting torch body edges, inner chamber has air perforations passage, and described air is worn
Passage top, hole has perforation air intake, is provided with main injection jet bottom described cutting torch chamber body, and described air perforations is with logical
Road all connects with main injection jet with mixing chamber.
Preferably, described air perforations passage is no less than 3 groups, 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 radial arrangement ringwise.
Preferably, described cutting torch composite bed is internal layer pyramidal structure, described peripheral accessory channel around cutting torch composite bed in
Centrosymmetry arranges.
Preferably, described cutting torch body is made up of parallel lumens and conical internal cavity.
Compared with prior art, the invention has the beneficial effects as follows: this two-way parallel connection air perforations, with compound cutting torch, is cut auxiliary
After helping gas to enter 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
Unified by the main injection jet blowout of cutting torch body, the quality of compound cutting torch centering thick plates cutting section has greatly improved, at cutting torch
Increasing cannelure and at least 3 tunnel air perforations passages on body, so can blow it without dead angle, air perforations is with logical
Road is designed as upper-wide and lower-narrow type structure, by increasing capacitance it is possible to increase air velocity, it is simple to blow away welding slag.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
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.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical scheme: a kind of two-way parallel connection air perforations is used and is combined cutting torch, 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 left and right sides pair
Claiming to be provided with peripheral accessory channel 3, described cutting torch body 1 inner chamber is provided with mixing chamber 7, described cutting torch composite bed 2 and peripheral auxiliary
The outlet side of passage 3 is all communicated in mixing chamber 7, and described cutting torch body 1 edge inner chamber has air perforations passage 4, institute
Stating air perforations passage 4 top and have perforation air intake 5, described cutting torch body 1 intracavity bottom is provided with main injection jet 6, described
Air perforations passage 4 all connects with main injection jet 6 with mixing chamber 7.
Wherein, described air perforations passage 4 is no less than 3 groups, and air perforations passage 4 is structure wide at the top and narrow at the bottom, institute
The multiple difference stating air perforations passage 4 upper channel and lower channel internal diameter is 1.2 times, and air perforations with passage 4 around main jet
Mouth 6 radial arrangement ringwise, described cutting torch composite bed 2 is internal layer pyramidal structure, and described peripheral accessory channel 3 is multiple around cutting torch
Closing layer 2 to be centrosymmetric arrangement, described cutting torch body 1 is made up of parallel lumens and conical internal cavity.
Concrete, 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 final 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,
So can blow it without dead angle, air perforations passage 4 is the structure narrowed from the width, and fat pipe is used for storing gas,
Narrow passage, for the guiding of gas, passes the gas through narrow passage big to the air-flow quantitative change in plate face simultaneously, and air pressure becomes big, it is simple to blow away
Welding slag, if auxiliary gas uses air to bore a hole, main pipeline cutting auxiliary gas is closed, and air enters from gas circuit in parallel and cuts
The cannelure of mouth body 1, directly arrives at the main injection jet 6 of cutting body 1, it is provided that perforation air by air perforations passage 4,
When boring a hole corrosion resistant plate, replacing high pressure nitrogen perforation by air perforations, the oxygen in air plays combustion-supporting effect so that wear
Hole is faster.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, permissible
Understand and these embodiments can be carried out multiple change without departing from the principles and spirit of the present invention, revise, replace
And modification, the scope of the present invention be defined by the appended.
