Description
Technical field
This utility model relates to a kind of metal-cutting device, particularly relates to the bocca of a kind of fly-cutting.
Background technology
It is in steel-making continuous casting cuts, owing to roll casting specification, thickness and the width etc. of steel are not quite similar and widely different,
At present in continuous casting tapping cutting, all use injection head cutting gun, during cutting, not only make that cutting gap is big, facet out-of-flatness, on
Turned-down edge, lower dross, and slag easily cling cutting torch and block and cause tempering phenomenon, and cutting torch is fragile.
Utility model content
The purpose of this utility model is to provide a kind of firepower, and greatly and firepower is concentrated, and mixed gas is uniform, and cut quality is high, speed is fast
The bocca of fly-cutting.
The technical solution of the utility model is:
The bocca of a kind of fly-cutting, including cone cutting head (1), is provided with cone in cone cutting head (1)
Mixed gas inner chamber (11), the bottom of the mixed gas inner chamber (11) of cone is provided with mixes the jet blower that gas inner chamber (11) communicates with cone
(101)；Described cone mixes gas inner chamber (11) top and has penetrated cartridge (12) and oxygen hose (13), the mouth of pipe of cartridge (12)
In horn-like, being provided with a taper and divide gas part (121) at the trumpet-shaped mouth of pipe, taper divides between base and the mouth of pipe of gas part (121)
Connected by horizontal stripe (1210) fixing, be fuel injection orifice (1211) between horizontal stripe (1210)；Described cone mixes gas inner chamber
(11) under crown center cross-under has high pressure oxygen supplying tube (14), high pressure oxygen supplying tube (14) to stretch in the mixed gas inner chamber (11) of cone
Portion.
Further: described cartridge (12) stretches into 2/3rds positions mixing gas inner chamber (11) at cone.
Further: described described oxygen hose (13) stretches into 1/4th positions mixing gas inner chamber (11) at cone.
Further: described cone mixes the gaseous mixture inner chamber that gas inner chamber (11) is oxygen and fuel.
The bocca of a kind of fly-cutting of the present utility model has the beneficial effect that this product structure is simple, practical, fire
Power is concentrated and violent, and firepower condenses, temperature high, fire distance, and cutting speed is fast, and precision is high, and face is smooth, and steel billet edge does not hangs
Slag, cutting torch is long for service life.
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model product.
Detailed description of the invention
The bocca of a kind of fly-cutting, including cone cutting head 1, is provided with the mixed gas of cone in cone cutting head 1
Inner chamber 11, the bottom of the mixed gas inner chamber 11 of cone is provided with mixes the jet blower 101 that gas inner chamber 11 communicates with cone；Described cone
Mixed gas inner chamber 11 top has penetrated cartridge 12 and oxygen hose 13, and the mouth of pipe of cartridge 12 is horn-like, at the trumpet-shaped mouth of pipe
Being provided with a taper and divide gas part 121, taper divides to be connected by horizontal stripe 1210 between the base of gas part 121 and the mouth of pipe to be fixed, horizontal stripe
Being fuel injection orifice 1211 between 1210, fuel disperses ejection from the fuel injection orifice 1211 of surrounding, and the fuel of dispersion ejection is very
Uniform with oxygen mix well；Described cone mixes gas inner chamber 11 crown center cross-under high pressure oxygen supplying tube 14, high pressure oxygen supplying tube
14 middle and lower parts stretching to the mixed gas inner chamber 11 of cone.
Described cartridge 12 stretches into 2/3rds positions mixing gas inner chamber 11 at cone.
Described described oxygen hose 13 stretches into 1/4th positions mixing gas inner chamber 11 at cone.
Described cone mixes the gaseous mixture inner chamber that gas inner chamber 11 is oxygen and fuel.
The foregoing is only preferred implementation of the present utility model, on protection domain of the present utility model is not limited in
Stating embodiment, every technical scheme belonging to this utility model principle belongs to protection domain of the present utility model.For this
For the technical staff in field, the some improvements and modifications carried out on the premise of without departing from principle of the present utility model, these
Improvements and modifications also should be regarded as protection domain of the present utility model.
