Abstract
The invention is a pit bolt pressure case device used for casting modeling and relates to a device for the metal machining field. When casting a huge work-piece, a san bore generates great case-raising force caused by high temperature to lead a grinding wheel to rise. In the prior art, massive iron blocks are pressed on the sand bore so as to eliminate the raising effect of the sand bore. The method not only affects the manufacturing schedule, but brings serious hidden safety troubles. The invention adopts to cast a concrete fixing frame in the side wall of the pit, arranges a pressing beam on the sand bore, two ends of which pass through a fixing hole at the upper end of the fixing frame, and drives into a drill key in the gap between the pressing beam and the fixing hole to lead the pressing beam to press on the sand bore tightly to eliminate the raising effect of the sand bore. The invention has the beneficial effects of light and handy structure, simple operation as well as safetyand reliability.
Description
Technical field:
The present invention relates to the metal manufacture field, in particular for the device of casting.
Background technology:
At present in casting field, need the large-scale component of casting more and more, bedded-in moulding has become the main method of producing heavy castings, as everybody knows, heavy castings when casting core is subjected to high temperature action and the case power of lifting that produces is sizable, as a heavily about bed casting of 10 tons, the case power of lifting during casting is between the 40-50 ton, that is to say by traditional foundary weight and press the case method, need foundary weight weight minimum about 50 tons, the foundary weight height reaches about 4 meters, to lift the core lifting effect elimination that case power causes, this brings very big inconvenience to execute-in-place, and very dangerous, press case to hinder the progress of producing with this traditional melt pit foundary weight, also brought very important hidden danger to safety in production.
Summary of the invention:
Purpose of the present invention is for providing a kind of novel pressure case apparatus that is used for after the casting and molding mould assembling, and melt pit door latch type that can be easy to operate and safe is pressed case apparatus.
The technical scheme that realizes the foregoing invention purpose is: it is to cast in the both sides concrete walls of melt pit respectively to be embedded with many fixed mounts that the melt pit door latch type that is used for casting and molding is pressed case apparatus, core is stretched out in the fixed mount upper end, have the fixing hole that penetrates in the end, the fixing hole penetration direction unanimity of both sides fixed mount in correspondence with each other, on core, place many and press beam, the fixing hole of respective fixation frame is passed at the two ends of pressure beam respectively, squeeze into drift in the gap of pressing beam and fixing hole, make and press beam to be pressed on above the core.
The pressure beam that is pressed on the core is pushed down core firmly, has eliminated the effect that case power is raised core of lifting.
It is light and handy that the present invention has structure, simple to operate, safe and reliable beneficial effect.Leakers phenomenon that causes inadequately owing to foundary weight weight and the shortcoming that too much takies effective production area owing to foundary weight have been solved.
Description of drawings
Fig. 1 is used for the structural representation of the melt pit door latch type pressure case apparatus of casting and molding for the present invention
Fig. 2 is a side of the present invention cross-sectional schematic
The specific embodiment
Now technical scheme of the present invention is described further by following embodiment.Fig. 1 and Fig. 2 have shown a kind of embodiment of the present invention, in the both sides of melt pit concrete walls 5, imbed many fixed mounts 1, fixed mount is made of the HT200 material, and core 4 is stretched out in the fixed mount upper end, and the end has the fixing hole that penetrates, on core, place many and press beam 3, press beam to make of " worker " word steel or channel-section steel, the fixing hole of respective fixation frame is respectively passed in the upper end of pressure beam, squeezes into drift 2 in the gap of pressing beam and fixing hole, drift has gradient, makes of the HT200 material.
