Abstract
The utility model relates to a dedicated cutting nozzle for diesel oil and oxygen flame cutting, belonging to the technical field of mechanical process. The dedicated cutting nozzle for diesel oil and oxygen flame cutting is composed of the head part of the cutting nozzle, the core of the cutting nozzle and the outer coating of the cutting nozzle; the head part of the cutting nozzle and the core of the cutting nozzle are arranged coaxially, the front part of the core of the cutting nozzle is inserted in the head part of the cutting nozzle for forming screwed connection, the large round surface of the head part of the cutting nozzle is evenly distributed with inclined holes, and back part of the core of the cutting nozzle is provided with a deep groove; the outer coating of the cutting nozzle is sheathed out of the core of the cutting nozzle, and an interstice between the core of the cutting nozzle and the outer coating of the cutting nozzle is 0. 1-0. 5 mm; preheating cavities are formed at the back parts of the core of the cutting nozzle and the outer coating of the cutting nozzle, and the lengths of the preheating cavities are 1. 5-10 mm. A cutting implement made of the dedicated cutting nozzle for diesel oil and oxygen flame cutting designed by the utility model can cut the steel material with thickness below 500 mm successfully.
Description
Technical field
The utility model relates to a kind of diesel oil-oxygen flame and cuts special-purpose cutting torch, belongs to the Machining Technology field.
Background technology
Splendid by gasoline and the roasting atomizer (number of patent application 200420006707.5) of liquid fuel-oxygen gas cutting and welding effect when gasoline-oxygen flame cuts of inventor's design at present, but when using diesel oil instead and do fuel, because the diesel oil droplet sizes after diesel oil thickness, the atomizing is bigger, the flame combustion of lighting is incomplete, over-emitting black exhaust, the normal cutting of influence is carried out.But do that the fuel oxygenation cuts steel and be that the industry (as large-scale civil engineering, heavy-duty machinery, panzer tank, various naval vessels etc.) of using diesel oil is in a large number welcome with diesel oil.
Summary of the invention
The purpose of this utility model is that a kind of diesel oil-oxygen flame of design cuts special-purpose cutting torch, changes the structure of existing cutting torch, so that the diesel oil droplet after the atomizing diminishes, makes the flame completing combustion of lighting.
Diesel oil-the oxygen flame that the utility model proposes cuts special-purpose cutting torch, is made up of cutting torch head, cutting nozzle core and cutting torch overcoat; Described cutting torch head and the coaxial installation of cutting nozzle core, the front portion of cutting nozzle core are inserted the cutting torch head and are become to be threaded, and are evenly equipped with inclined hole on the big garden face of cutting torch head, and the rear portion of cutting nozzle core is provided with deep trouth; Described cutting torch overcoat is enclosed within the outside of cutting nozzle core, and the gap between cutting nozzle core and the cutting torch overcoat is the 0.1-0.5 millimeter; Cutting torch stamen and cutting torch overcoat rear portion form preheating cavity, and the length of preheating cavity is the 1.5-10 millimeter.
Diesel oil-oxygen flame with the utility model design cuts special-purpose cutting torch, makes cutting implement, can successfully cut the steel material below 500 millimeters.
Description of drawings
Fig. 1 is the schematic diagram that the utility model diesel oil-oxygen flame cuts special-purpose cutting torch.
Among Fig. 1, the 1st, the cutting torch head, the 2nd, cutting nozzle core, the 3rd, cutting torch overcoat front portion, the 4th, cutting torch overcoat rear portion, the 5th, be distributed on the inclined hole on the face of the big garden of cutting torch head, the 6th, the deep trouth at cutting nozzle core rear portion, the 7th, the preheating cavity that cutting torch stamen and cutting torch overcoat rear portion form, δ is the cavity between cutting torch overcoat and cutting nozzle core, L is the length of the preheating cavity of cutting torch stamen and the formation of cutting torch overcoat rear portion.
Concrete described mode
Diesel oil-the oxygen flame that the utility model proposes cuts special-purpose cutting torch, and its structure is made up of cutting torch head 1, cutting nozzle core 2 and cutting torch overcoat 3 as shown in Figure 1.Cutting torch head 1 and cutting nozzle core 2 coaxial installations, the front portion of cutting nozzle core 2 is inserted the cutting torch head and is threaded for 1 one-tenth, is evenly equipped with inclined hole 5 on the big garden face of cutting torch head, and the rear portion of cutting nozzle core is provided with deep trouth 6.Cutting torch overcoat 3 is enclosed within the outside of cutting nozzle core 2, and the gap delta between cutting nozzle core and the cutting torch overcoat is the 0.1-0.5 millimeter; Cutting torch stamen 2 and cutting torch overcoat rear portion 4 form preheating cavity 7, and the length L of preheating cavity 7 is the 1.5-10 millimeter.
After being installed in the special-purpose cutting torch of the utility model design on the cutting torch, oxygen that comes out from cutting torch head atomizer and vaporific diesel oil just enter the gap of cutting nozzle core and the formation of cutting torch overcoat by the aperture on the cutting torch head 15 (diameter is 6 holes of 1 millimeter of Φ), both gaps are generally the 0.1-0.5 millimeter, cutting nozzle core 1 and cutting torch overcoat rear portion 4 are to be slidingly matched, and just (total sectional area of groove is the 5-30 millimeter 18 deep trouths 6 above cutting nozzle core for mixed vaporific diesel oil and oxygen
2) spray and enter preheating cavity 7, light flame in the preheating cavity of back with 4 heating of cutting torch overcoat rear portion with vaporific diesel oil gasification.Thereby obtain satisfied diesel oil-oxidizing flame.
Among the embodiment of the present utility model, the cutting torch head is 30 ° of conical surfaces, on have 6 Φ 1 inclined holes to be distributed on the face of the big garden of cutting torch head, it is 16 millimeters apertures of Φ that cutting torch overlaps anterior external diameter, 1.1 millimeters of internal diameters are that 18-8 type stainless steel is made.Cutting torch cover rear portion is that silver soldering is connected with cutting torch cover front portion, and the outlet overall diameter is 7 millimeters of Φ, and cutting nozzle core is connected with the cutting torch head threads, and the anterior diameter of mouth core is 10.6 millimeters of Φ, and there are 18 deep trouths at mouth core rear portion, and it is of a size of (0.5 * 1 * 18=9 millimeter
2) the preheating cavity degree of depth is 3 millimeters, the steel material of cutting thickness below 100 millimeters smoothly.
The utility model can with the applicant's gasoline-oxygen manual cutting torch, semi-automatic cutting torch and the supporting use of numerical control cutting torch.
