Description
Technical field
This utility model belongs to welding cutting technique field, relates to steel under a kind of case of emergency, copper product welds incisory friction and ignites weldering pen.
Background technology
Solder technology and cutting technique be engineer operation important means, but generally require during its operation specialty electrical equipment.Need the power supply of the energy above power of kilowatt output and heavy electric welding machine such as SMAW commonly used at present, gas welding then needs the high pressure special equipment of store oxygen and acetylene gas, involves engineering big, and operator need to be subject to special training.This greatly limits motor-driven in the in particular cases emergent repair welding task such as power failure, field, sleety weather, flexibly, launch efficiently.It addition, in high-altitude, underground, under water equal energy source be inconvenient under the extreme condition supplied, these traditional emergency maintenance methods also cannot be put to good use.Meanwhile, in the emergency maintenance of water and gas conduit, heating network and engineering cable, recover to use function in the urgent need to the emergent fast quick-recovery of welding method original position or part easily；In the rescue and relief work of earthquake, fire etc., fire-fighting detaching, also in the urgent need to a kind of without outside resources and equipment and cutting tool easy to use.
For this situation, patent (CN200810227057.X) one manual thermit welding electrode and preparation and application thereof, by thermite (CuO powder, Cu2O powder, NiO powder, Fe2O3Powder and Al powder), slag former (B2O3Powder, SiO2Powder, CaO powder and CaF2Powder), alloying constituent (Fe powder, Mn powder and Si powder) adopt ball mill mix homogeneously according to a certain percentage, take shape in paper cylinder, be loaded on miscellaneous part constitute thermit welding electrode.But, there is welding powder complicated component in this patent, manufacturing process is loaded down with trivial details, relatively costly, and sleeve such as easily comes off after being fixed on plug at the shortcoming.A kind of Portable welding pen of patent (201110126018.2), it is necessary to the instrument such as match, lighter of use is ignited, and uses inconvenience.
Utility model content
Technical problem to be solved in the utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of cheap friction is ignited weldering pen.
Concrete technical scheme of the present utility model is as follows:
A kind of weldering pen of igniting that rubs, including pencil, pencil afterbody seals with externally threaded bare terminal end, in pencil on bare terminal end, loads thermite, the section of igniting and friction firing device successively, the described section of igniting adopts exothermic welding pyrophoric powder, described friction firing device is made up of glass dust, plucking copper wire, seal disc and bracing wire, and described plucking copper wire runs through glass dust, and one end is connected with the section of igniting, the other end is connected through seal disc with bracing wire, and pencil is sealed by the external safety paper in bracing wire；
Also including the pen container that diameter is more bigger than pencil, be used for being enclosed within outside pencil, described pen container one end is with the female thread matched with the external screw thread of bare terminal end, and the other end seals.
The composition of described thermite includes exothermic agent, slag former and alloying constituent three part, adopts the thermite used in prior art.Such as the composition of patent 201110126018.2 exothermic agent is: CuO powder 60 ~ 70wt%, Al powder 15 ~ 20wt%；The composition of slag former is: CaF2Powder 4 ~ 8wt%, CaSO4Powder 5 ~ 7wt%；Alloying constituent composition is: ferromanganese powder 1 ~ 3wt%, ferronickel powder 2 ~ 4wt%.Wherein CuO powder is industry copper scale, and oxygenation efficiency is 70 ~ 80%.In ferromanganese powder, the content of Mn is the content of 88wt%, Fe is 10wt%, and all the other are impurity；In ferronickel powder, the content of Ni is the content of 55wt%, Fe is 43wt%, and all the other are impurity.All thermite raw material particle sizes are all between 150 order ~ 200 orders.
Above-mentioned weldering pen also includes having the pen container that the pvc pipe of higher-strength is made, pen container diameter 1 ~ 2mm bigger than pencil, length ratio pencil length 4 ~ 5mm, and pen container is enclosed within outside pencil when welding pen and not using；During use, extract pen container out, by coordinating quickly and easily between the external screw thread of the female thread on pen container and pencil afterbody bare terminal end, it is possible to play effect that is fixing and that support weldering pen.
The preparation flow of mechanical friction delayed type Self lighting Portable welding pen is as follows: each raw material is dried 6 ~ 8 hours by (1) in electric heating constant-temperature blowing drying box (T=80 DEG C)；(2) weigh each raw material by described mass percent, mix in high speed mixer, prepare thermite；(3) medicament of the section of igniting will add bonding agent, and by bonding wherein for the bottom of plucking copper wire, briquet；(4) thermite being filled in diameter is 11 ~ 14mm, and length is in the papery pencil of 200 ~ 250mm, and the section of igniting is installed in one end, and the other end is installed bare terminal end and sealed；(5) load glass dust at the section of igniting end, make plucking copper wire imbed wherein, by the plucking copper wire other end by being connected with bracing wire with the seal disc of minimum circular hole, adopt safety paper to be sealed by pencil；(6) pencil loading diameter 1 ~ 2mm bigger than pencil, in the pen container of length ratio pencil length 4 ~ 5mm, namely weldering pen is made.
The sparking mode of weldering pen is three grades of igniting.Namely being ignited by mechanical friction delayed type Self lighting device, light the section of igniting after igniting, the section of igniting is ignited thermite again.Thermite generation thermit reaction needs higher temperature, and the temperature that logical fireworks and firecrackers powder burning produces can not cause thermit reaction, only just can ignite with commercially available special exothermic welding pyrophoric powder.The special exothermic welding section of igniting can not be lighted by match or lighter again, can only use the spray gun that flame combustion temperature is higher, but spray gun is not readily portable.So devising mechanical friction Self lighting device, plucking copper wire and glass dust ignition by friction is utilized to light spontaneous combustion section.
This utility model has the advantages that and advantage:
(1) screw thread design that the shaft of a writing brush and bare terminal end are unique make swift to operate while, the length of the shaft of a writing brush adds safety during operation；
(2) adopt mechanical friction Self lighting device to carry out igniting lighting, make pilot operation convenient.
