Description
Technical field
This utility model belongs to welding cutting technique field, relates to steel, copper product under a kind of case of emergency and welds incisory Self lighting Portable welding pen.
Background technology
Weld job and cutting operation are two kinds of very important engineer operation modes, need the electrical equipment of specialty during operation.The equipment that welding equipment as conventional at present is is main flow with electric welding, its volume is heavy, handles not easily, it is necessary to jumbo power supply is as support, and can launch very strong ultraviolet light when using, when thus relating to small-scale local welding, it will lose more than gain.At some in particular cases, such as field work, underground work, and when some are extreme, traditional welding and cutting operation are often restricted because of Equipment, therefore in the urgent need to a kind of without outside resources and equipment and welding cutting tool easy to use.
For this situation, utility model ZL200620024766.4 has invented a kind of pocket welding pen, it is made up of parts such as the shaft of a writing brush, cartridge case, taper combustion-supporting shade, match board head, fire-retardant head, the sections of igniting, thermite inside cartridge case contains oxide and the similar electrode coating composition of composition being used as the dimethyl siloxane of bonding agent, cartridge case of aluminium powder, magnesium powder, titanium valve, ferrum, including silicate, carbonate, titanium dioxide, ferromanganese and ilmenite etc..This patent is separately formed for the slag former form for cartridge case, simultaneously containing more valuable titanium valve inside thermite, relatively costly.And too short for the fire-retardant head length that operator is hand-held so that operator's safety coefficient when implementing welding is not high.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
Problem to be solved in the utility model is to provide a kind of cheap Self lighting Portable welding pen.
The technical solution of the utility model is as follows:
A kind of Self lighting Portable welding pen; including papery pencil; internal filling thermite; pencil head is provided with friction point duration and degree of heating, has, between friction point duration and degree of heating and thermite, the section of igniting, and the section of igniting adopts exothermic welding pyrophoric powder; friction point duration and degree of heating upper cover has papery protection set; pencil afterbody one end seals with externally threaded bare terminal end, and the composition of described friction point duration and degree of heating is identical with the composition of match end, and the outside coating of described papery protection set has the composition identical with matchbox both sides frictional layer；
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 length of described protection set is 15 ~ 20mm.
The composition of described friction point duration and degree of heating is potassium chlorate, sulfur, manganese dioxide, phosphorous layer be mainly composed of red phosphorus, glass dust etc..
The composition of described thermite includes exothermic agent, slag former and alloying constituent three part, adopts the thermite of 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 the pvc pipe pen container with higher-strength, pen container diameter 1 ~ 2mm bigger than pencil, length ratio pencil length 4 ~ 5mm.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 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) thermite being filled in diameter is 10 ~ 15mm, and length is in the papery pencil of 200 ~ 250mm, and the section of igniting and friction point duration and degree of heating are installed in one end, and the other end is installed bare terminal end and sealed；(4) protection set on igniter head one end shield；(5) 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 friction point duration and degree of heating and phosphorous layer friction, 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 common fireworks and firecrackers powder burning produces can not cause thermit reaction, only just can ignite by the commercially available special exothermic welding section of igniting.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 friction point duration and degree of heating, friction point duration and degree of heating is utilized to ignite with the friction of red phosphorus layer.The medicament of the section of igniting and friction point duration and degree of heating all adds bonding agent, briquet, it is simple to assemble.
This utility model has the advantages that and advantage:
(1) cartridge case of pen, protection set, the shaft of a writing brush, bare terminal end, the section of the igniting common material of selection are welded, cheap；
(2) 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；
(3) adopt friction point duration and degree of heating and coating friction to ignite from introduction row to light, make pilot operation convenient；
(4) the protection set of coating has the effect of protection against the tide.
