The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is described further:
Test finds that in the preparation process of the cutting silk material of manual under water fly-cutting material, the speed of preparation silk material is 40-120m/min, if throwing speed is slow, efficient is low, and throwing speed is fast, breaks a material easily.The alignment of silk material is carried out on silk material straightener, and alignment speed is about 5-22m/min; If alignment speed is slow, alignment efficient is low, and alignment speed is fast, and the alignment of silk material does not reach requirement, the assembling of influence and incising pipes.
In addition, cut Cu in the silk material among the present invention
2The adding of O powder and CuO powder is in order to utilize Cu
2A large amount of heats are emitted in O powder and CuO powder and aluminium, iron reaction, are supported in carrying out smoothly of cutting under water.Work as Cu
2O grain weight amount percentage is less than 3%, and CuO grain weight amount percentage was less than 5% o'clock, and liberated heat is few, and cutting speed is less, and works as Cu
2O grain weight amount percentage is greater than 20%, and CuO grain weight amount percentage was greater than 25% o'clock, and reaction is violent, and burning velocity is too fast, is not easy control.Cu
2Adding in the time of O powder and CuO powder can be so that course of reaction be steady, lasting, and cutting process also relatively steadily under water.The adding of Al powder is because aluminium and Cu
2A large amount of heats are emitted in O powder and the reaction of CuO powder, and its content range is by Cu
2The content decision of O powder and CuO powder.
The adding of rare earth cerium can improve the efficiency of combustion of cutting material, promotes cutting material fully burning in oxygen.When rare earth cerium percentage by weight less than 1% the time, very little to the raising effect of efficiency of combustion, in 1～7% scope; Along with the increase of rare earth cerium weight ratio, also increasing to the raising of efficiency of combustion, but surpass 7%; To the raising of efficiency of combustion with 7% compare change little; And rare earth cerium price is higher, in order to practice thrift cost, elects 1～7% as.
Incising pipes cooperates requirement with the size that is equipped with of cutting silk material; Not so can cause incising pipes and cut the asynchronous of silk material burning; The rule that we draw be the ratio scope of wall thickness of diameter and incising pipes of cutting silk material between 2.1～3, the burning synchronism is better.Like this, adopt the tubing of different size, interior dress diameter, the different cutting of a radical material can be assembled into the manual fly-cutting material of different size, cut.Be the dimensions of concrete several kinds of manual fly-cutting materials below:

Cutting silk material diameter is 2.4mm, is about to be 600mm, and totally 3 are assemblied in the incising pipes.
Specification 2: select the forging and pressing seamless steel pipe of the about 0.8mm of wall thickness for use, adopt electroplating technology again, outer within it both sides plate the copper plate of thick approximately 0.1mm.The total wall thickness of tubing is about 1mm; Internal diameter 6.6mm, external diameter 8.6mm, the incising pipes of preparation are about and are 600mm.
Cutting silk material diameter is 2.4mm, is about to be 600mm, and totally 5 are assemblied in the incising pipes.
Specification 3: select the forging and pressing seamless steel pipe of the about 0.8mm of wall thickness for use, adopt electroplating technology again, outer within it both sides plate the copper plate of thick approximately 0.1mm.The total wall thickness of tubing is about 1mm; Internal diameter 8mm, external diameter 10mm, the incising pipes of preparation are about and are 600mm.
Cutting silk material diameter is 2.4mm, is about to be 600mm, and totally 7 are assemblied in the incising pipes.
Find that through experimental study the diameter of said cutting silk material and the ratio scope of the wall thickness of incising pipes can reach combustion efficiency preferably 2.1～3.
According to the different demands of practical applications, can adopt different percentage by weight powder core processing cutting materials, for example:
The steel pipe that step 3, employing Forging Technology are prepared from is as the incising pipes of outside, and the inside and outside electroplating technology that adopts of steel pipe respectively is coated with the thick copper plate of 0.1mm; Polyethylene tape is wrapped in the incising pipes outside or epoxy resin is coated in the incising pipes outside and forms and have insulation and water-proof function insulating barrier;
Wherein, 3 undercuts are cut a material be assembled in the said incising pipes inner chamber, form manual fly-cutting material under water, wherein, two is the mild steel crust, and one is the aluminium crust.
In addition, in order to form hollow structure in the incising pipes center, can insert a unnecessary cutting silk material at center position earlier, after twining outside composite metal belt, again that the center is a unnecessary undercut cuts a material and extracts out.

Material of the present invention can be applied to the cutting of metal material under water or nonmetallic materials; Usually nonmetallic materials can be concrete, brick or rock.
In engineering practice; Cutting material need utilize diced system to accomplish cutting process under water; Diced system comprises arc ignition system, air supply system, cutting gun three parts, and arc ignition system is made up of knife switch 5,24V battery striking power supply 6, lead 7, copper run-on tab 8, and its effect is to be the electric arc that ignites of manual fly-cutting material 11 under water; Just can disconnection valve knife-like switch 5 after manual under water fly-cutting material 11 smooth combustions, thus striking power supply 6 broken off; Air supply system is made up of carbon fiber fire-fighting oxygen cylinder 9 and oxygen gas circuit 13, and its effect is for cutting gun 12 provides oxygen, keeps cutting material 11 further sustained combustions, and removes the slag of cut workpiece 10; Cutting gun 12 links to each other with carbon fiber fire-fighting oxygen cylinder 9 through oxygen gas circuit 13, link to each other with striking power supply 6 through lead 7, and 11 pairs of workpiece 10 of clamping cutting material cuts.
Its course of work is at first, to carry out the preceding preparation of cutting; Each parts of system have been connected; Striking power supply 6 the two poles of the earth connect cutting gun 12 and copper run-on tab 8 (positive and negative all can) respectively, and knife switch 5 is in off-state, and striking power supply 6 is in more than the waterline with carbon fiber fire-fighting oxygen cylinder 9 all the time; Secondly, cut under water, cutting gun 12, workpiece 10, copper run-on tab 8 are entirely below waterline; Staff on the bank closes knife switch 5; The cutting gun 12 of the hand-held manual under water fly-cutting material 11 of clamping of the operating personnel of cutting, and the oxygen flow control valve on the flicking cutting gun 12 is under water seen oxygen off, and cutting material 11 ends are contacted with copper run-on tab 8 and paddling; Electric arc ignites; After treating that arc burning is stable, staff's disconnection valve knife-like switch 5 on the bank, and the underwater operation personnel move on to workpiece 10 places with cutting material 11 ends and cut; At last, cutting is dismantled each parts after accomplishing, and is contained in the tool box.
