Description
Technical field
The utility model relates to a kind of exothermic welding mould, specifically a kind of mould for realizing metallic conductor welding.
Background technology
At present, exothermic weld is the important means realizing being fixedly connected with between metal.Tradition exothermic welding mould is due to technological deficiency, and time in operation toward lighting-up tuyere sparking, in reaction chamber, reaction is violent, and welding solution very easily sprays from lighting-up tuyere even likely washes die cover open, hurts personal safety.When current the sector is in order to overcome sparking, welding solution, to the injury of human body, adopts electronic lighter, and operator in the comparatively distant location sparking of distance mould, but can also exist following Railway Project when traditional moulds is lighted a fire with common lighter or electronic ignition gun:
1, when traditional moulds is with common lighter sparking, operator must in the face of lighting-up tuyere, vigorous reaction in reaction chamber, and welding solution very easily sprays from lighting-up tuyere even may wash die cover open, jeopardizes life safety.
2, when traditional moulds adopts electronic ignition gun to strike sparks, operator can avoid coming to harm away from mould, but during reaction chamber reaction, pyrosol may be splashed on electronic ignition gun wire, destroys electronic ignition gun, electronic ignition gun is shortened service life.
Utility model content
The purpose of this utility model is, overcomes the shortcoming of traditional exothermic welding mould, provides the novel metal exothermic welding mould that a kind of security performance is higher.
It is as follows that the utility model solves the problems of the technologies described above taked technical scheme:
A kind of special exothermic welding mould, described mould has reaction chamber (5), conductor slot (7) and welding chamber (8), and between reaction chamber (5) and welding chamber (8), there is drainage trough (6), also be provided with die cover, described die cover covers described mould, and the top of mould is provided with a protection portion, described protection portion has an igniting chamber, this igniting chamber is connected with reaction chamber (5), and igniting chamber place is reserved lights powder, reaction chamber establishes welding agent in (5), the top in described igniting chamber arranges the back-fire relief part of a transverse direction, and from formation one back-fire relief groove between this back-fire relief part with die cover, and back-fire relief groove connects again two openings, respectively as bocca (4) and lighting-up tuyere (3).
Further, preferably, the metallic conductor of welding is needed to put into described conductor slot (7).
Further, preferably, described reaction chamber puts into aluminium material pad in (5), and places welding agent on aluminium material pad.
Further, preferably, described die cover and mould form complete mould.
After the utility model takes technique scheme, lighting-up tuyere is arranged on die cover top, back to bocca during igniting, even if so use common lighter also can not hurt operator, be furnished with back-fire relief groove in die cover, prevents welding solution from spraying from mould; The requirement of use safety can be reached, there is good technique effect.
Other features and advantages of the utility model will be set forth in the following description, and, partly become apparent from description, or understand by implementing the utility model.The purpose of this utility model and other advantages realize by structure specifically noted in write description, claims and accompanying drawing and obtain.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail, to make above-mentioned advantage of the present utility model definitely.
Fig. 1 is the schematic diagram of the protection portion of the die cover of the special exothermic welding mould of the utility model;
Fig. 2 is the structural representation of the mould of the special exothermic welding mould of the utility model;
Fig. 3 is the structural representation of the special exothermic welding mould of the utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.
The utility model is formed primarily of mold, die cover, lighting-up tuyere, bocca, back-fire relief groove, reaction chamber, drainage trough, welding chamber.Wherein, die cover is linked by metal duckbilled and connects, and after mold and die cover are combined, forms three parts communicated: reaction chamber, drainage trough and welding chamber in inside.In actual use procedure, adopt special aluminium dish reaction chamber and drainage trough to be kept apart, welding powder and ignition powder are positioned in reaction chamber; And need lighter be equipped with.
Lighter is used to strike sparks back to die point burner, after lighting ignition powder, thermit reaction is there is in welding powder in reaction chamber, the pyrosol of this reaction, penetration aluminium dish, welding chamber is flowed to by drainage trough, and in welding chamber by the abutting end founding of two conductors to be connected together, thus complete intermetallic chemistry welding.
Vigorous reaction in reaction chamber after sparking, traditional exothermic welding mould welding solution or flame even can wash die cover open by the ejection of sparking mouth; Novel exothermic welding mould is equipped with back-fire relief groove, welds solution and is blocked by back-fire relief groove, can not spray from mould in reaction chamber during vigorous reaction.
Specifically, a kind of special exothermic welding mould, described mould has reaction chamber 5, conductor slot 7 and welding chamber 8, and between reaction chamber 5 and welding chamber 8, there is drainage trough 6, also be provided with die cover, described die cover covers described mould, and the top of mould is provided with a protection portion, described protection portion has an igniting chamber, this igniting chamber is connected with reaction chamber 5, and igniting chamber place is reserved lights powder, welding agent is established in reaction chamber 5, the top in described igniting chamber arranges the back-fire relief part of a transverse direction, and from formation one back-fire relief groove 2 between this back-fire relief part with die cover 1, and back-fire relief groove connects again two openings, respectively as bocca 4 and lighting-up tuyere 3, wherein, die cover 1 is made up of graphite material.
Further, preferably, the metallic conductor of welding is needed to put into described conductor slot 7.
Further, preferably, put into aluminium material pad in described reaction chamber 5, and place welding agent on aluminium material pad.
Further, preferably, described die cover and mould form complete mould.
After this grounding body takes technique scheme, safety in utilization is higher, is below implementation process:
The first step, first by needing the metallic conductor of welding to put into conductor slot 7, put into aluminium material pad in reaction chamber 5 after, pour welding agent into, more reservedly at lighting-up tuyere 3 place light powder;
Second step, after preparation completes, to light a fire at lighting-up tuyere 3 place back to mould bocca 4 with lighter;
Send calorize reaction in 3rd step, reaction chamber, solution flows into welding chamber 8 along drainage trough 6, is welded together by metallic conductor;
4th step, treat to react completely in mould, take out conductor, define the entirety be connected firmly.
After the utility model takes technique scheme, lighting-up tuyere is arranged on die cover top, back to bocca during igniting, even if so use common lighter also can not hurt operator, be furnished with back-fire relief groove in die cover, prevents welding solution from spraying from mould; The requirement of use safety can be reached, there is good technique effect.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
