Quick metal cutting strip by means of combustion

Abstract

The invention discloses a quick metal cutting strip by means of combustion, which comprises an iron pipe (1). One end of the iron pipe (1) serves as a gas inlet end (2), the other end of the iron pipe (1) serves as a gas outlet end (3), a gas channel I (4) is arranged in the center of the iron pipe (1), a plurality of galvanized iron wires (5) are uniformly inserted into the iron pipe (1) and are fixed in the iron pipe (1) after being tightly pressed by the iron pipe (1), the external section of each galvanized iron wire (5) is closely attached onto the inner wall of the iron pipe (1), the inner sides of the galvanized iron wires (5) enclose the gas channel I (4), a gap is reserved between the outer sides of each two adjacent galvanized iron wires (5), an independent gas channel II (7) is formed between each gap and the iron pipe (1), a safety area (8) is arranged among an end opening of the gas inlet end (2) and the galvanized iron wires (5) and is used for partitioning the galvanized iron wires (5) from an oxygen supply gas channel of a cutting gun, and the oxygen supply gas channel of the cutting gun is respectively communicated with the gas channel I (4) and the gas channels (7) through the safety area (8).

Description

technical field [0001] The invention provides a quick cutting strip for burning metal. Background technique [0002] At present, the cutting of alloy metals on the market includes oxygen cutting, gasoline cutting, plasma cutting, etc. The performance of these cutting machines is as follows: oxygen and gasoline cutting machines cannot cut copper, aluminum, cast iron, and stainless steel; plasma cutting machines Although these materials can be cut, the depth of cutting is limited by the thickness of the plate, and the thicker the cutting plate, the larger the volume of the machine; and the underwater cutting strip uses alloy metal consumables, which are not only expensive, but also structurally complex. Contents of the invention [0003] The invention provides a quick cutting strip for burning metal, which not only has good use effect, but also has wide application range, can cut various materials, and has low production cost. [0004] The present invention adopts the foll...
