Abstract
The utility model discloses a novel brazing furnace, comprising a furnace body (1) and a main ventilation pipe (2) arranged on the furnace body (1); sub-ventilation pipes (3) are connected on the main ventilation pipe (2); a plurality of branch ventilation pipes (31) are arranged on the sub-ventilation pipes (3); the branch ventilation pipes (31) are threaded into the furnace body (1); the number of the sub-ventilation pipes (3) is two; the two sub-ventilation pipes (3) are respectively arranged at both sides of the furnace body (1); and the number of the branch ventilation pipes (31) is 28. Compared with the prior art, the novel brazing furnace has the advantages that as the main ventilation pipe is connected with the sub-ventilation pipes, and the sub-ventilation pipes are provided with a plurality of branch ventilation pipes which are threaded into the furnace body, the protective gas has uniform concentration at any place in the furnace body; therefore, in the brazing process, the uniformly concentrated protective gas facilitates the wettability of the solder and protects the workpiece from being oxidized so as to ensure the quality of the braze welding workpieces.
Description
Technical field
The utility model relates to the welding field of materials such as carbide alloy and carbon steel, particularly a kind of novel brazing furnace.
Background technology
The workpiece that assembles is placed on the method for welding in the heating furnace that is generated heat by resistance wire, is called furnace brazing.The characteristics of this technology are, whole workpiece is heated, and it is heated evenly, and workpiece deformation is little.The former employing air furnace of the heating furnace of furnace brazing, but owing in air, heat between its workpiece, easily oxidized; and programming rate is very slow; be unfavorable for brazing flux removal oxide-film,, substituted by vacuum furnace brazing and protective atmosphere furnace brazing gradually so its application is subjected to certain restriction.And vacuum brazing furnace is the periodic resistance furnace, furnace temperature must be reduced to low temperature after each soldering is finished after, workpiece just can be come out of the stove (preventing that workpiece is oxidized), it is longer that every furnaceman does the cycle, efficient is lower.
In the prior art, adopt special atmosphere oven mostly.According to the difference of protective atmosphere, special atmosphere oven can be divided into two kinds: reducing gas and inert gas stove.Reducing gas generally uses H
2Or CO, inert gas is generally used Ar, N
2With He etc.Usually the scheme that adopts is, a passage is set on body of heater, and protective gas directly is blown in the body of heater by this hole, in brazing process, both can help the wetting of solder, has protected workpiece not oxidized again, has guaranteed the quality of soldering work piece.But the defective that exists is, because protective gas just directly is blown in the body of heater by passage, makes that gas concentration is big the other side near pore, and is more intense for the protection of workpiece; And the other side away from pore, because temperature is very high in the stove, gas vaporization is very big, and gas concentration is less relatively, for the protection ratio of workpiece a little less than, quality problems will appear in the soldering effect of the workpiece at this place so.
Summary of the invention
Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of concentration that can make the protective gas in the body of heater evenly, guarantee the novel brazing furnace of soldering work piece quality.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of new-type soldering oven, comprise body of heater, be arranged at the main breather line on the described body of heater, it is characterized in that: on described main breather line, connect and divide breather line, breather line was provided with some breather lines in described minute, and described breather line inserted and worn to described body of heater.
Breather line was two in described minute, was arranged at the body of heater both sides respectively; Described breather line is 28.
Compared with prior art; advantage of the present utility model is; divide breather line owing to connect on the main breather line in the utility model; divide breather line to be provided with a some breather line that wears to the described body of heater; just can make in the body of heater that the concentration of protective gas everywhere is even, in brazing process, both can help the wetting of solder; protect workpiece not oxidized again, guaranteed the quality of soldering work piece.
Description of drawings
Fig. 1 is the side view in the utility model embodiment Center Vent tube road;
Fig. 2 is the utility model embodiment Center Vent tube road structural representation;
Fig. 3 is that A-A among Fig. 2 is to cutaway view.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3, a kind of novel brazing furnace, comprise body of heater 1, be arranged at the main breather line 2 on the described body of heater 1, on described main breather line 2, connect and divide breather line 3, breather line 3 was provided with some breather lines 31 in described minute, and described breather line 31 wears to described body of heater 1.
Described breather line 31 is 28.
Feed protective gas by main breather line 2, as nitrogen, through being arranged at the branch breather line 3 of body of heater 1 both sides, entering a breather line 31 that wears to the body of heater 1, this breather line 31 can use high temperature resistant porcelain tube to make.Because breather line 31 is provided with some, can spread all over each place in the body of heater 1, so just can make in the body of heater 1 that the concentration of protective gas everywhere is even; in brazing process; both can help the wetting of solder, and protect workpiece not oxidized again, guarantee the quality of soldering work piece.
Claims (3)
1, a kind of new-type soldering oven, comprise body of heater (1), be arranged at the main breather line (2) on the described body of heater (1), it is characterized in that: go up to connect at described main breather line (2) and divide breather line (3), described minute breather line (3) be provided with some breather lines (31), described breather line (31) wears to described body of heater (1).
2, new-type soldering oven as claimed in claim 1 is characterized in that: described minute breather line (3) be two, be arranged at body of heater (1) both sides respectively.
3, as claim 1 or the described new-type soldering oven of claim 2, it is characterized in that: described breather line (31) is 28.
