Abstract
The invention relates to a metal combustible cutting rod which comprises a thin-wall hollow metal outer tube. A plurality of metal capillary tubes and a plurality of solid metal rods are arranged in the thin-wall hollow metal outer tube and arrayed symmetrically and uniformly at intervals in the thin-wall hollow metal outer tube; the diameter of each metal capillary tube is smaller than the diameter of each solid metal rod; the diameter of the thin-wall hollow metal outer tube is 6-12mm, and the wall thickness is 0.3-1.5mm; and the ratio of the total effective material cross section area of the metal capillary tubes and the solid metal rods to the inner cross section area of the thin-wall hollow metal outer tube is 0.6-0.8. As the combustible consumable for oxidative cutting, the metal combustible cutting rod disclosed by the invention is very easy to combust in pure oxygen and can release sufficient heat continuously to heat the surface of cut metal to the metal combustion point rapidly so that the cut metal combusts without stop under the condition of supplying oxygen continuously and the flowing oxygen takes away the slag generated from the combustion of the metal without stop. The metal combustible cutting rod disclosed by the invention has light weight and is convenient to carry, easy to operate and safe to use.
Description
Technical field:
The present invention relates to a kind of cutting rod, be specifically related to a kind of cutting rod made from metal, add oxygen and get final product continuous burning, it can be used for Metal Cutting or heating.
Technical background:
The method of thermal cutting of the prior art has the oxidation cutting and dissolves two kinds of cuttings.Oxidation cutting is that metal burn in high purity oxygen and forms the oxide of good fluidity, borrows the oxygen line with the metal oxide base material formation breach that blows off simultaneously.Like the acetylene cutting, this cutting mode cost is low, but shortcoming is that the flame burning-point is low, only is suitable for carbon steel.And acetylene gas was both dangerous, and also not environmental protection belongs to flammable explosive gas.Dissolve cutting and then be and utilize thermal source to make to be cut the material local melting, lean on line that the deposite metal base material that blows off is formed breach, cut like cut and plasma.But the only suitable cutting metal book plate of cut, and apparatus expensive.The cutting line of plasma cutting can be inert gas or air, and its advantage is a safety, thick metallic plate in can cutting, but the equipment of plasma cutting is heavy.
Summary of the invention:
To the problem that exists in the above-mentioned prior art, the objective of the invention is to propose a kind of metal burning cutting rod, its fusing point can cut thick sheet metal and nonmetallic materials up to 3600 ℃, and equipment is light, easy to carry, simple to operate, safe in utilization.
The technical scheme that the present invention is taked for its purpose of realization: a kind of metal burning cutting rod, comprise the thin-walled hollow metal outer pipe, establish some metal capillaries and some solid metal rods in the pipe.
Said metal capillary and said solid metal rod are arranged in the thin-walled hollow metal outer pipe at interval symmetrically and evenly; Said metal capillary diameter is equal to or less than the diameter of solid metal rod; The diameter of said thin-walled hollow metal outer pipe is 6-12mm, and pipe thickness is 0.3-1.5mm.
What said solid metal rod and the effective material section of metal capillary were amassed is 0.6～0.8 with the ratio of thin-walled hollow metal outer pipe cross section inner area always.
Said solid metal rod, metal capillary and thin-walled hollow metal outer pipe adopt ferroalloy, kirsite or nickel alloy material to make.
Metal burning cutting rod operation principle:Lead to into oxygen with certain pressure from metal burning rod one end.Flow through uniformly in excellent gap of oxygen solid metal in rod and the metal capillary.Meeting naked light lights metal capillary earlier.The metal capillary solid metal rod that ignites that in oxygen, burns.Make the sustained combustion of whole metal burning rod.
The metal burning rod of burning is moved to the metal covering that will cut, and satisfied the required condition of Metal Cutting this moment, and the Metal Cutting process begins, along with the continuous burning of metal burning rod, constantly to being cut Metal Cutting until metal burning rod after-flame.
Beneficial effect of the present invention:
Only aerobic gas of cutting process and metal burning cutting rod need not other combustion mediums.
Fusing point can cut thick sheet metal and nonmetallic materials up to 3600 ℃.
Cutting operation can also can carry out in water on land.
And equipment is light, easy to carry, simple to operate, safe in utilization.

Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further specified.
Fig. 1 is the embodiment of the invention one front view;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
Fig. 3 is the embodiment of the invention two front views;
Fig. 4 is the B-B cross-sectional view of Fig. 3.
Among the figure 1, metal capillary, 2, the solid metal rod, 3, the thin-walled hollow metal outer pipe.
The specific embodiment:
The present invention utilizes some metal in oxygen, to burn, and discharges the chemical phenomenon of big calorimetric simultaneously, is made into a kind of novel burning consumptive material metal burning cutting rod.
Three conditions below the structure of this metal burning cutting rod must satisfy in the Metal Cutting process:
1) this metal bar is easy to ignited in purity oxygen.
2) can constantly discharge enough heat, will be cut metal covering rapidly and reach the metal burning-point.
The oxygen supply that 3) can continue makes to be cut metal and constantly to burn, and the oxygen that flows is simultaneously constantly taken away the slag that produces after the metal burning.
The structure example of metal burning cutting rod:
Fig. 1,2 is depicted as embodiment one structure, comprises thin-walled hollow metal outer pipe 3, in thin-walled hollow metal outer pipe 3, is located at three metal capillaries 1 and three solid metal rods 2.Metal capillary and solid metal rod are arranged in the thin-walled hollow metal tube at interval symmetrically and evenly, and the metal capillary diameter is less than the diameter of solid metal rod.The pipe thickness of thin-walled hollow metal outer pipe is 0.3mm, and diameter is 6mm.The summation that solid metal rod and the effective material section of metal capillary are amassed is about 0.7 with the ratio of thin-walled hollow metal outer pipe cross section inner area.
Fig. 3,4 is depicted as embodiment two structures, comprises thin-walled hollow metal outer pipe 3, in thin-walled hollow metal outer pipe 3, is provided with three metal capillaries 1 and four solid metal rods 2.Metal capillary and solid metal rod are arranged in the thin-walled hollow metal tube at interval symmetrically and evenly, and the metal capillary diameter equals the diameter of solid metal rod.The pipe thickness of thin-walled hollow metal outer pipe is 1mm, and diameter is 12mm.The summation that solid metal rod and the effective material section of metal capillary are amassed is 0.6 with the ratio of thin-walled hollow metal outer pipe cross section inner area.
Solid metal rod, metal capillary and thin-walled hollow metal outer pipe adopt ferroalloy, kirsite or nickel alloy material in above-mentioned two examples.
The present invention accomplishes three processes of Metal Cutting.
1), will be cut the metal surface and be heated to burning-point playing a cutpoint place, makes it the reaction that in pure oxygen, takes fire, and propagate to metal lower layer.
2), get rid of the slag that combustion reaction generates, sever metal along thickness direction.
3) heat continuously and utilize slag heat constantly the metal overlayer of otch leading edge to be heated to burning-point, make it to continue to produce combustion reaction with oxygen.
Said process constantly repeats, and the Metal Cutting process is just carried out continuously.
