Abstract
The non-circular seamless medicine core silver wire in a kind of cross section, comprises silver solder pipe and is wrapped in the medicine core in silver solder pipe hollow posts chamber, it is characterized in that: described silver solder pipe is the hollow seamless solder pipe of ellipsoidal cross section structure.The non-circular seamless medicine core silver wire in cross section prepared by the utility model, has anti-rolling effect, can accurately locate during welding, realizes efficient, automatic welding; Simultaneously welding wire deflection is good, can continuous drawing, increases substantially welding wire follow-up drawing tube reducing efficiency.
Description
Technical field
The utility model relates to a kind of welding material, is specifically related to the non-circular seamless medicine core silver wire in a kind of cross section.
Background technology
Flux-cored wire is a kind of novel welding material, compared with solid core welding wire, have that welding efficiency is high, constituent adjustment flexibly, energy-saving material-saving, solder flux consumption be few, pollute the advantages such as little, appearance of weld is attractive in appearance, is applicable to continuous automatic welding.
Silver solder fusing point is moderate, welding usability good, has good intensity, toughness, electric conductivity, thermal conductivity and corrosion resistance, is a most widely used class hard solder, particularly green cadmium-free silver brazing alloy, is the emphasis that domestic and international soldering industry was paid close attention in recent years.
Patent 201110435173.2 disclosed " silver-based flux-cored wire and manufacture method ", adopts seamless extrusion to fill with core manufacturing technique method and manufactures Ag-Cu-Zn seamless flux-cored wire.But the method single extruding billet limited mass, each billet can only be squeezed into single line base, there is welding wire, brazing flux breaks empty hidden danger.This patent silver wire is circular, and for the welding of the non-circular workpiece in cross section, the method welding efficiency is low, cannot realize continuous welding, and its application has certain limitation.
Summary of the invention
The purpose of this utility model provide for weak point existing in above-mentioned prior art just a kind of can continuously, the non-circular seamless medicine core silver wire in cross section of efficient welding.
The purpose of this utility model realizes by following technique measures:
The non-circular seamless medicine core silver wire in cross section of the present utility model comprises silver solder pipe and is wrapped in the medicine core in silver solder pipe hollow posts chamber; Described silver solder pipe is the hollow seamless solder pipe of ellipsoidal cross section structure.
The core of medicine described in the utility model is made up of medicinal powder; Described medicine core accounts for 10.5 ~ 20.0% of welding wire percentage by weight.
The beneficial effects of the utility model are as follows:
1, the utility model has anti-rolling effect, can accurately locate during welding;
2, the medicinal powder of seamless medicine core silver wire of the present utility model not easily leaks, and can accurately control brazing flux consumption;
3, seamless medicine core silver wire silver solder of the present utility model can be indefinite length, increases substantially welding wire follow-up drawing tube reducing efficiency.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
Sequence number in figure: 1 silver solder pipe, 2 medicine cores.
Detailed description of the invention
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, the non-circular seamless medicine core silver wire in cross section of the present utility model comprises silver solder pipe 1 and the medicine core 2 be wrapped in silver solder pipe hollow posts chamber; Described silver solder pipe is the hollow seamless solder pipe of ellipsoidal cross section structure; Described medicine core is made up of medicinal powder; Described medicine core accounts for 10.5 ~ 20.0% of welding wire percentage by weight.
More specifically: the percentage by weight of silver solder each component described in the utility model is: silver-colored 44.6 %, copper 27.4 %, zinc 25.6 %, tin 2.1 %, indium 0.3%; Finished product welding wire traditional Chinese medicine powder filling rate is 15.3%, wherein borax 15.3 %, borate 72.69%, activating agent 12.11%; The wire melting temperature of preparation is 640 ~ 682 DEG C.
Above-mentioned welding wire realizes by following method:
1st step, by silver-colored 44.6 %, copper 27.4 %, zinc 25.6 %, tin 2.1 %, indium 0.3% carries out preparing burden, melting, and is cast into ingot, ingot casting is placed in annealing furnace and anneals, annealing temperature 540 ~ 560 DEG C;
2nd step, by borax 15.3 %, borate 72.69%, the proportions filling rate of activating agent 12.11% is the medicinal powder of 15.3%, medicinal powder is heated to 560 ~ 580 DEG C and is molten into liquid state;
3rd step, adopts pressurizing unit to extrude the ingot casting of having annealed, forms seamless silver solder pipe;
4th step, adopts draw-out device by the seamless silver solder pipe of the liquid brazing flux suction of the 2nd step, obtains seamless medicine core silver wire.
