Description
Technical field
The invention belongs to welding field, relate to a kind of welding equipment, particularly relate to a kind of self-propagating welding rod based on electronic striking.
Background technology
Solder technology is the important means that civilian, engineering machinery and military equipment and manufacture, repairing and emergency maintenance are installed.Traditional welding manner mainly adopts the mode such as electric welding, gas welding, can the source of welding current of the above power of kilowatt output and heavy electric welding machine but SMAW needs, gas welding then needs the high pressure special equipment of the imflammable gas such as store oxygen and acetylene, involve engineering very big, and operator must be subject to special training.This greatly limits in the wild, power failure, in the situation such as sleety weather emergent welding repairing task motor-driven, flexible, launch efficiently.In addition, under the extreme specific condition supplied is inconvenient in high-altitude, underground, some energy such as under water, these traditional emergency maintenance methods also cannot effectively be put to good use.
Therefore develop a kind of without the need to a large amount of outside resources and main equipment, easy to use, simple to operate, efficient, energy-conservation new welding technology and welding material, the deficiency making up conventional soldering techniques has seemed very necessary.
For meeting the demand that social development proposes solder technology, a lot of scholar has dropped in the research in this field.And achieve some achievements in research.Such as patent CN200810227057.X proposes a kind of manual thermit welding electrode, patent 201210391069.2 proposes a kind of without electric welding direct type welding rod, patent 201110126018.2 discloses a kind of Portable welding pen, patent 201210159201.7 discloses a kind of simple and easy without electric welding pen, patent ZL200620024766.4 has invented a kind of pocket welding pen, though above-mentioned patent autonomous Design has also produced the welding material satisfied the demands, but its emphasis is all in the research of welding agent formula, and very few for the research of welding rod structure.Welding rod structure citation form is the sealing of pencil one end encapsulation plug, and one end plug seals, and peripheral hardware sleeve pipe is protected and welded the use of handle, uses naked light to light a fuse and can induce reaction.There is following hidden danger in this welding rod structure, need the burning things which may cause a fire disaster point combustion wires such as hand-held match, lighter during welding, hand being placed in welding rod front end exists certain risk; Blasting fuse leaks outside, and meets naked light and very easily burns in unwitting situation, thus cause serious security incident.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of safe and reliable self-propagating welding rod based on electronic striking.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
Based on the self-propagating welding rod of electronic striking, comprise handle, plug and pencil, the link of described handle has external screw thread, is threaded connection with plug, and the boss of described plug is coaxially fixedly connected with pencil, the other end encapsulation plug sealing of described pencil;
Described handle there are battery case and switch groove, the two ends of battery case are respectively spring and sheet metal, spring is connected with first contact of two on link respectively by wire with sheet metal, described plug there are two corresponding second contacts, when handle is connected with plug, the first contact and the second contact;
The section of igniting that described pencil has 3-5mm long at encapsulation plug one, load welding agent between the section of igniting and plug, the medicine head portion of electric igniter is rolled in the section of igniting, and the wire of electric igniter is connected with the second contact with the string holes on plug boss through welding agent.
Described pencil is the stainless steel tube of internal diameter 12-14mm wall thickness 0.4-0.8mm, one end uses plug sealing, the other end uses the sealing of encapsulation plug, pencil is built with welding agent, welding agent and encapsulation are equipped with the exothermic welding pyrophoric powder of 3-5mm as the section of igniting between filling in, and the medicine head part of electric igniter is wrapped in the section of igniting.
Be pressed into the cylinder that length is 2-3mm after described encapsulation plug is mixed with binding agent by exothermic welding pyrophoric powder, mainly play the effect of encapsulation welding agent.Binding agent can adopt common glue, and the amount of binding agent should to ensure that exothermic welding pyrophoric powder is fully wetting, and can well be shaped to suitable.This encapsulation plug can ignite instantaneously when the section of igniting is burnt, but the naked lights low in calories such as match flame can not be lighted.
Described battery case is equipped with No. 7 batteries.
Described switch groove is built with touch-switch.
Described welding agent can be, by percentage to the quality: CuO powder 58.0%-70.0%, Al powder 13.0%-18.0%, Si-Ca alloyed powder 5.0%-6.7%, CaF
2powder 5.0%-6.3%, B powder 0.7%-1.5%, Fe powder 4.8%-9.5%, Mn powder 0.4%-1.0%.
Wired in series is used successively in the first contact on battery, touch-switch and handle; Two wires of electric igniter are connected with the second contact on plug after string holes through on welding agent, plug.In use, after the link of handle and plug threaded engagement, the first contact can contact with the second contact, press touch-switch, circuit is connected instantaneously, the raw burning of electric igniter medicine hair, ignite the section of igniting, the burning of encapsulation plug disappears then, and the welding agent that simultaneously ignites welds.
Compared with prior art, the present invention has following beneficial effect and advantage:
(1) handle and plug adopt threaded engagement, and compact conformation is reliable.
(2) handle is easily dismantled, and can repeatedly use, and namely a handle can join branched pencil.
(3) pencil adopts thin-wall stainless steel, has enough rigidity, has good protective effect to welding agent, do not need additional sleeve pipe; And in welding process, stainless steel tube melts, absorption portion heat of reaction, ensure the stationarity of reaction, molten metal liquid is mixed in weld metal, effectively regulates weld metal composition and improves its mechanical property, it also avoid the inclusion defect of the weld metal that modes such as adopting paper tube causes simultaneously.
(4) do not need the burning things which may cause a fire disaster point combustion wires such as hand-held match, lighter during welding, improve the security of welding operation further; Without leaking outside blasting fuse, it also avoid welding rod in unwitting situation and meeting the accident that burning occurs naked light.
