Description

A kind of macro-energy cutting pen
Technical field
The utility model belongs to the cutting technique field, relates to a kind of macro-energy cutting pen that is used in emergency circumstances cutting the orcible entry operation.
Background technology
Cutting operation is the necessary means of excision metal structure obstacle in rescue and relief work and the fire-fighting orcible entry, plays crucial effects for the security of the lives and property of rescuing the people in the very first time.Method for hot cutting commonly used at present is gas cutting and plasma cutting: gas cutting needs heavy high-pressure oxygen cylinder and acetylene gas bottle; The plasma cutting needs the auxiliary equipment of large power supply and other heavy costlinesses.Yet do not have electric, with a varied topography, awful weather in emergency circumstances in earthquake and ice and snow disaster etc., the thermal cutting equipment that these are traditional or can't start perhaps can't transport the place and in paralyzed state of suffering from disaster easily to.And instrument such as hydraulic tongs and locking pliers are cut in lighter cold cut commonly used, need machinery and manpower again, have hindered the flexible and efficient expansion of disaster relief programs.Therefore, press for a kind of portablely, simple to operate, do not rely on the novel cutting tool of power supply.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of power supply, cutting tool easy and simple to handle of not relying on is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of macro-energy cutting pen comprises pencil, and the pencil head is provided with igniter head, and inside is full of medicinal powder, between igniter head and the medicinal powder section of igniting is arranged, and the pencil afterbody has externally threaded bare terminal end sealing with an end; Described igniter head is consistent with the employed medicine component of common match end, and the described section of igniting adopts the special-purpose pyrophoric powder of commercially available exothermic welding, and the composition of described medicinal powder comprises exothermic agent and diluent two parts, and the composition of exothermic agent is: CuO powder 45~50wt%, MnO 2Powder 15~20wt%, Al powder 15~16wt%; The composition of diluent is: SiO 2Powder 4~5wt%, CaO powder 3~7wt%, CaF 2Powder 3~5wt%, calcium-silicon powder 4~5wt%.
Above-mentioned macro-energy cutting pen also comprises pen container, and the pen container diameter is than the big 1~2mm of pencil, and length is than the long 4~5mm of pencil, and pen container one end has the internal thread that matches with the external screw thread of bare terminal end.When cutting pen does not use, be enclosed within the pencil outside.During use, extract pen container out,, can play a part fixing and the support cutting pen by the cooperation between the external screw thread of internal thread on the pen container and pencil afterbody bare terminal end.
The other end of described pen container prevents that with the sealing of plastics disk igniter head from being ignited by accident.
In the above-mentioned cutting pen, the effect of the exothermic agent in the pencil is that violent chemical reaction-thermit reaction takes place, and emits huge energy, with to be cut burn through, reaches the purpose of cutting.The effect of diluent is the severe degree that reduces thermit reaction, makes cutting pen burning steadily, burning velocity in controlled scope, easy operating.All more than 150 orders, wherein the CuO powder is industrial copper scale to institute's medication powder raw material particle size, and the particle top layer is oxidized, and heart portion still is a metallic copper, and oxygenation efficiency is 70~80%; The mass ratio of each element is Si:Ca:Fe=56%:30%:14% in the calcium-silicon powder.
The preparation flow of cutting pen is as follows: (1) will dry respectively except that the Al powder of easy oxidation and each component the calcium-silicon powder; (2) take by weighing each raw material by described mass percent, in high speed mixer, fully mix, make medicinal powder; (3) medicinal powder being loaded in diameter is 11~14mm, and length is in the papery pencil of 150~200mm, and an end is installed the section of igniting and igniter head, and the other end is installed the bare terminal end sealing; (4) pencil is packed into the big 1~2mm of diameter, in the pen container of the long 4~5mm of length, cutting pen is promptly made.
The using method of cutting pen is, pencil is extracted out from pen container, and pen container is screwed on the bare terminal end, grasp pen container, cutting pen is aimed at position to be cut, with match or lighter firing point duration and degree of heating, through 2~3 seconds, the section of igniting caused medicinal powder generation thermit reaction, at this moment make the cutting pen combustion flame be close to place to be cut, utilize huge heat that medicinal powder generation thermit reaction emits with metal molten, the air-flow that reaction produces dashes molten metal and removes, thereby reaches the purpose of cutting.
Pen container described in the utility model adopts the pvc pipe with higher-strength to make, and an end has internal thread with plastics disk sealing, other end design, matches with the external screw thread of bare terminal end.Pen container on the one hand can be carried out protection to the lower papery pencil of intensity, and convenient the storage and transportation can prevent that on the other hand igniter head accident from igniting, and prevents the generation of accident.And when implementing cutting, the pen container extraction is screwed on the bare terminal end, bare terminal end and pen container landing when preventing to hold pen container have increased the distance of operator's hand from cutting flame simultaneously, have improved security.
Sparking mode of the present utility model is three grades of igniting.Promptly by match or lighter firing point duration and degree of heating, light the section of igniting after igniter head burning, the section of the igniting medicinal powder that ignites again.Reason is that medicinal powder generation thermit reaction needs higher temperature, and the temperature that common fireworks and firecrackers powder burning produces can not cause thermit reaction, has only the commercially available special-purpose exothermic welding pyrophoric powder of employing just can ignite.And special-purpose exothermic welding pyrophoric powder can not be lighted by match or lighter, can only adopt the higher spray gun of flame combustion temperature, but spray gun is not easy to carry.So designed and the consistent igniter head of the employed medicine component of common match end.The medicament of igniter head all adds bonding agent with the pyrophoric powder of the section of igniting, and briquet is convenient to assembling.
The beneficial effects of the utility model are: (1) macro-energy cutting pen does not need power supply, and source of the gas is supplied with, and the huge energy that the chemical reaction that only relies on medicinal powder self to continue is emitted can be finished the cutting task efficiently; (2) macro-energy cutting pen structural design small volume and less weight can be carried, cutting operation safety, easy, quick; (3) the utility model has realized that really a kind of earthquake, fire etc. of being adapted in emergency circumstances implement metal structure obstacle cutting, and the very first time is rescued the conveniently cutting tool of life property safety of people.
