Abstract

The invention provides a three-gun flame cutting device at least comprising a first flame cutting gun head, a second flame cutting gun head and a third flame cutting gun head. The first flame cutting gun head is arranged on the next working position of the second flame cutting gun head; the third flame cutting gun head is located on the previous working position of the second flame cutting gun head. The cutter enables the preheating flame area and the cutting speed to be adjusted according to the material and the thickness of steel plates, thereby realizing portable multifunctional intermittent cutting. The risk of cutting crack of the steel is controlled and the technology and equipment guarantee is provided for stable production of high quality products.

Description

A kind of flame-cutting plant
Technical field
The invention belongs to field of machining, be specifically related to a kind of three rifle flame-cutting plants.
Background technology
Along with the tremendous development of domestic and international Wide and Thick Slab production technology, the fire of the high-quality such as abrasion-resistant stee, high-strength steel, mould steel, high-carbon steel and high-alloy steel, high strength specialities cuts and splits quality risk problem, this type of steel has the features such as carbon equivalent is high, crack sensitivity is strong usually, steel plate very easily occur when gas flame cuttiug cracking, especially the winter, rainy season crack probability larger.In order to ensure the steady production of this series products, the exploitation that the fire of innovation cuts equipment and technology thereof just seems particularly urgent.
Fig. 1 is a kind of typical traditional manual flame cutting machine, and this flame cutting machine is only provided with a flame cutter head, can realize the Length-fixing cutting to steel plate.This type flame cutting machine can only carry out the Length-fixing cutting of steel plate, cannot realize preheating and the after heat function of steel plate easy to crack, and after cutting, cracking very easily appears in product.
If overall preheating before carrying out gas flame cuttiug to steel plate easy to crack often can be run in actual production; energy consumption certainly will be caused so too high; whole steel billet temperature is high cannot carry out normal portable operation cutting, needs to invest newly-built Special pre-heating device simultaneously and production cost certainly will be caused to cross the problems such as high.
In order to overcome the problems referred to above, need many people when utilizing special equipment to carry out gas flame cuttiug to steel plate easy to crack, synchronously carry out front and back preheating, this measure will cause the waste of manpower and financial resources greatly, simultaneously because artificial hand holding equipment carries out preheating to cutting position, all can produce certain influence to the accurate control of temperature and the accuracy of position thereof, with regard to direct, plate property uniformity be had an impact like this.
Summary of the invention
For the above-mentioned deficiency of prior art, the invention provides a kind of three rifle flame-cutting plants, the cutting of this novel flame is arranged in order out at a certain distance by three rifle heads, work under assigned operation condition simultaneously, the first and last rifle head carry out preheating and after heat respectively to cutting part, middle rifle carries out Length-fixing cutting, achieves synchronization job.
Flame-cutting plant of stating of the present invention comprises at least the first flame cutter head, the second flame cutter head and the 3rd flame cutter head, described first flame cutter head is arranged at the subsequent work position of the second flame cutter head, and described 3rd flame cutter head is arranged at a upper operating position of described second flame cutter head.
Preferably, described first flame cutter head, the second flame cutter head and the 3rd flame cutter head are arranged on same straight line.
Preferably, the flame temperature of described first flame cutter head is 250 ~ 400 degrees Celsius, and the flame temperature of described second flame cutter head is 2200 ~ 2800 degrees Celsius, and the flame temperature of described 3rd flame cutter head is 150 ~ 350 degrees Celsius.
Preferably, the spacing of described first flame cutter head and the second flame cutter head is 10 ~ 30cm, and the spacing of described second flame cutter head and the 3rd flame cutter head is 10 ~ 30cm.
Preferred, the spacing of described first flame cutter head and the second flame cutter head is 15 ~ 25cm, and the spacing of described second flame cutter head and the 3rd flame cutter head is 10 ~ 25cm.
The present invention three rifle flame cutting machine can according to unlike material, steel plate thickness is by the spacing of rifle head and middle cutting gun head before and after regulating and go out gas quantity and carry out preheat flame area and cutting speed regulates, and achieves the cutting of portable multifunctional batch (-type).
Present invention achieves three flame cutter synchronization jobs, decrease manpower, financial resources drop into, improve production efficiency and product quality.
Accompanying drawing explanation
Fig. 1, traditional flame cutting machine schematic diagram.
Fig. 2 a-2c is respectively top view, side view and the front view of three rifle flame cutting machines.
Accompanying drawing identifies:
1, tracheae; 2, flame cutting torch; 3, burning torch; 4, support; 5, guide rail.
Detailed description of the invention
Be below the preferred embodiments of the present invention, it is only used as the explanation of the application instead of restriction.
See accompanying drawing 2, three work flame cutter head on same cutting machine simultaneously; Three rifle heads are arranged in order out at a certain distance, and logical straight line works asynchronously, and the first and last rifle head carry out preheating and after heat respectively to cutting part, and middle rifle carries out Length-fixing cutting; Transversely arranged first flame cutter head and the 3rd can according to different steel plate thickness flame cutter head, by regulating with the spacing of middle cutting gun head and going out gas quantity and regulate preheat temperature.
The flame temperature of described first flame cutter head is 450 degrees Celsius, and the flame temperature of described second flame cutter head is 2850 degrees Celsius, and the flame temperature of described 3rd flame cutter head is 350 degrees Celsius.
The spacing of described first flame cutter head and the second flame cutter head is 20cm, and the spacing of described second flame cutter head and the 3rd flame cutter head is 25cm.
Aforesaid three rifle heads also can as required not according to arranged in a straight line, and namely those skilled in the art can adjust its arrangement as required flexibly.
Present invention achieves three flame cutter synchronization jobs, solve in the high strength specialities production processes such as abrasion-resistant stee, high-strength steel, mould steel, high-carbon steel and high-alloy steel and cut problem of Cracking, decrease economic loss, decrease manpower, financial resources drop into, improve production efficiency and product quality.
