Abstract
The utility model discloses and a kind ofly overcome zinc-aluminium flux-cored wire and to break the zinc-aluminium ingot casting of powder, comprise the ingot casting body with upper shed die cavity, the trapezium structure that the vertical section of described die cavity is big up and small down or up big and down small step structure.The utility model advantage is, by changing zinc-aluminium ingot mould cavity shape, to add the size of ingot casting die cavity, increase medicinal powder ratio; The trapezium structure that the vertical section of its die cavity is big up and small down or up big and down small step structure can divide a part in drawing process, be applied to pressure on powder base, further reduction powder base extrudes speed, thus solve zinc-aluminium ingot casting latter half welding wire and to break powder defect, improve production efficiency, reduce production cost; Fill out powder by the die cavity of these two kinds of structures and can obtain the higher powder base of density, stop the defects such as flux-cored wire bulge.
Description
Technical field
The utility model relates to the manufacture field of zinc-aluminum brazing filler metal, especially relates to a kind ofly overcoming zinc-aluminium flux-cored wire and breaking the zinc-aluminium ingot casting of powder.
Background technology
Zinc-aluminium flux-cored wire is divided into seamed and seamless two kinds of forms as connecting the special solder of Al-zn-mg-cu alloy, and seamed cored wire utilizes sheet zinc-aluminum brazing filler metal and brazing flux to roll to form, and not only easily leaks powder, and welding powder is perishable thus lose activity, seamless flux-cored wire medicinal powder is put into zinc-aluminium ingot casting die cavity to be pressed into by adding, compared with seamed welding wire, although overcome leakage powder, the shortcomings such as medicine core inefficacy, but, due to zinc-aluminium ingot casting to fill out the upper and lower internal diameter of powder die cavity equal, in pressing process, welding powder is easily caused to extrude prior to allumen ingot casting, according to metal flow principle, this is because moulding good metal fluidity is also better, so the flowing of zinc-aluminium ingot casting is slower than welding powder flowing, ingot casting has not also squeezed welding powder and has all flowed out, welding wire beginning and the ending of an easy generation ingot casting extruding do not have welding powder, particularly ending is particularly serious, the disconnected powder rate of flux-cored wire reaches 25%.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind ofly to overcome zinc-aluminium flux-cored wire and to break the zinc-aluminium ingot casting of powder.
For achieving the above object, the utility model can take following technical proposals:
Described in the utility modelly a kind ofly overcome zinc-aluminium flux-cored wire and to break the zinc-aluminium ingot casting of powder, comprise the ingot casting body with upper shed die cavity, the trapezium structure that the vertical section of described die cavity is big up and small down or up big and down small step structure.
The bottom of described die cavity is arc surface structure.
The utility model advantage is the shape by changing zinc-aluminium ingot casting die cavity, adds the size (namely increasing medicinal powder ratio) of ingot casting die cavity; When suppressing in die cavity welding powder being inserted ingot casting, the die cavity of trapezium structure or step-like structure can divide a part of pressure be applied in drawing process on welding powder, reduce the extrusion speed of welding powder, thus solve zinc-aluminium ingot casting latter half welding wire and to break the defect of powder, improve yield rate, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
embodiment 1:
As shown in Figure 1, described in the utility modelly a kind ofly overcome zinc-aluminium flux-cored wire and to break the zinc-aluminium ingot casting of powder, comprise the ingot casting body 1 with upper shed die cavity 2, the trapezium structure that the vertical section of die cavity 2 is big up and small down, the bottom of die cavity 2 is arc surface structure.Adding man-hour, by filling out powder device, the welding powder after mixing, drying and processing being filled in the die cavity 2 of this trapezium structure, by obtaining the zinc-aluminium flux-cored wire of required specification after preheating, extruding, rolling, wire drawing.Due to the pressure be applied on welding powder can be reduced during extruding, reduce the discharge rate of welding powder, make the disconnected powder rate of flux-cored wire be reduced to 12% from 25%.
embodiment 2:
As shown in Figure 2, described in the utility modelly a kind ofly overcome zinc-aluminium flux-cored wire and to break the zinc-aluminium ingot casting of powder, comprise the ingot casting body 1 with upper shed die cavity 2, the step structure that the vertical section of die cavity 2 is big up and small down, the bottom of die cavity 2 is arc surface structure.The die cavity 2 of this kind of structure, when filling out powder, can fill out powder from bottom to top by the ledge structure subregion of die cavity 2 successively, to obtain higher (welding powder) powder base of density; By the zinc-aluminium flux-cored wire of required specification can be obtained after preheating, extruding, rolling, wire-drawing process.Die cavity due to step-like structure can divide the pressure be partly applied on powder base, substantially reduces the pressure be applied on powder base, compared with embodiment 1, reduce further the discharge rate of welding powder, make the disconnected powder rate of flux-cored wire be reduced to 1%; Powder is filled out in the die cavity subregion of step structure simultaneously, can obtain the powder base that density is higher, can stop the defects such as flux-cored wire bulge.
Claims (2)
1. overcome zinc-aluminium flux-cored wire to break the zinc-aluminium ingot casting of powder, comprise the ingot casting body (1) with upper shed die cavity (2), it is characterized in that: the trapezium structure that the vertical section of described die cavity (2) is big up and small down or up big and down small step structure.
