Description
Technical field
The present invention relates to the Machining Technology field, be applicable to that especially the subsumption of drawing the cork of heavy castings processing is educated device.
Background technology
In foundry production, have the favorable mechanical performance for guaranteeing castings material, need in molten steel pouring course, add inovulant, addition manner has various ways, and wherein commonly used is current-following inoculation.
In the modern industrial technology, also more and more to demand large-scale, super-huge foundry goods, also increasingly high to the quality requirement of foundry goods; Like large-scale injection moulding machine template, bed piece and 5MW, 6MW wind power hub, base foundry goods etc.; Poured weights reaches more than 50 tons, and the casting ladle capacity of employed inoculation device is low in the prior art, then wants a plurality of casting ladles to pour into a mould when producing heavy castings; Then to the cast of foundry goods processing with breed and caused bigger technical barrier, reduced production efficiency; Adopt the cast inoculation device to have trivial operations in addition in the prior art, pour into a mould not steadily, breed insufficiently, the inovulant absorptivity is low, the cost height, and pregnant effect is bad, the defective of casting quality difference.
Summary of the invention
The applicant is to producing the heavy castings cast in the above-mentioned existing production technology and breeding shortcoming such as difficulty; A kind of cast and inoculation device of heavy castings rational in infrastructure are provided; Thereby can realize in the use that molten iron and inovulant flow into simultaneously; The inovulant absorptivity is high, and cost is low, and pregnant effect is good.
The technical scheme that the present invention adopted is following:
A kind of cast of heavy castings and inoculation device comprise sandbox, and said sandbox top is provided with cup, and said cup bottom is connected through running gate system and sandbox are inner; Being positioned at the sandbox top has cast seat bag through stent support, and an end is provided with the carbon rod plug of control molten iron turnover in the said cast seat bag, and a sidewall of said cast seat bag is provided with the control carbon rod and descends mobile device beyond the Great Wall; Also comprise inoculation device, the inovulant hopper is anchored on the sidewall of cast seat bag, and the outflow pipeline of said inovulant hopper is connected with cup, and the flow export of the flow export of said outflow pipeline and carbon rod plug is on same straight line.
Its further technical scheme is:
The control carbon rod descends the structure of mobile device to be beyond the Great Wall: comprise the support bar parallel with the carbon rod plug, said support bar top connects vertical with it connecting rod through tripod, and the end of said connecting rod is connected with carbon rod plug top through securing member; Also comprise connecting rod, said connecting rod is connected on three corner steadies of cast seat bag one sidewall, and said connecting rod is connected through hinge arrangement with support bar, and is extended with spanner at its hinge arrangement end;
Cast seat bag bottom is provided with molten iron conical outlet end, and said carbon rod plug bottom is provided with the plug that matches with molten iron conical outlet end;
The inovulant feed hopper bottom is equipped with the knife switch of control inovulant flow size.
Beneficial effect of the present invention is following:
The present invention installs cast seat bag through the sandbox top, and in a side of cast seat bag inoculation device is set, and pours into a mould and molten iron and inovulant can flow to realization pregnant effect in the cup simultaneously when breeding casting process.
Owing to can hold the bigger ladle of capacity or a plurality of ladle in the cast seat bag; Needing in the prior art to have avoided the troublesome operations of a plurality of casting ladle cast; Can satisfy the cast of the many casting ladles of super-huge foundry goods and breed needs, the inovulant flow can be according to the openings of sizes of the demand regulating gate switch of reality.
The present invention is simple in structure, applying flexible, and environmental suitability is strong, and is easy to operate, and cast is steady, and pregnant effect is good, and cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an A portion partial enlarged drawing among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the cast of heavy castings of the present invention and inoculation device comprise sandbox 10, and sandbox 10 tops are provided with cup 8, and cup 8 bottoms are through running gate system 9 and 10 inner connections of sandbox; Be positioned at sandbox 10 tops and cast seat bag 1 arranged through stent support; An end is provided with the carbon rod plug 4 of control molten iron turnover in the cast seat bag 1; Cast seat bag 1 bottom is provided with molten iron conical outlet end (not marking among the figure), and carbon rod plug 4 bottoms are provided with the plug (not marking among the figure) that matches with molten iron conical outlet end; One sidewall of cast seat bag 1 is provided with control carbon rod plug 4 and moves up and down device: see Fig. 2; The structure that control carbon rod plug 4 moves up and down device is: comprise the support bar 2 parallel with carbon rod plug 4; Support bar 2 tops connect vertical with it connecting rod 13 through tripod 14, and the end of connecting rod 13 is connected with carbon rod plug 4 tops through bolt 12; Also comprise connecting rod 15, connecting rod 15 is connected on three corner steadies 16 of cast seat bag 1 one sidewalls, and connecting rod 15 and support bar 2 are connected through hinge arrangement, and are extended with spanner 3 at its hinge arrangement end.Also comprise inoculation device; Inovulant hopper 5 is anchored on the sidewall of cast seat bag 1; Inovulant hopper 5 bottoms are equipped with the knife switch 6 of control inovulant flow size; The outflow pipeline 7 of inovulant hopper 5 is connected with cup 8, and the flow export of outflow pipeline 7 and the flow export of carbon rod plug 4 are on same straight line.
In the actual use, injection ladle in cast seat bag 1 at first, inovulant hopper 5 inovulant of packing into; During cast, spanner 3 is down pulled, thereby carbon rod plug 4 is moved upward; This moment, the plug of carbon rod plug 4 bottoms separated with molten iron conical outlet end; Molten iron can flow in the cup 8 from the flow export of cast seat bag 1 bottom, simultaneously, opens the knife switch 6 of inovulant hopper 5 bottoms; Inovulant flows into cup 8 through flowing out pipeline 7, and running gate system 9 inflow sandboxes 10 internal productions through cup 8 bottoms go out foundry goods 11 then.Because the flow export of outflow pipeline 7 and the flow export of carbon rod plug 4 can make molten iron and inovulant flow into simultaneously on same straight line, inovulant and molten iron even contact breed evenly fully, improve casting quality.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion within protection scope of the present invention, can be done any type of modification referring to claim to the qualification of invention.
