Abstract
The invention relates to a grid-shaped airflow guiding device used for cooling a large-sized annular cast, which comprises a first annular connecting plate and a second annular connecting plate which are arranged in parallel, wherein the first connecting plate and the second connecting plate are connected by at least one vane evenly distributed. The airflow guiding device can quickly and evenly cool the large-sized annular cast and avoid deformation, stress concentration and cracks caused by the non-uniform cooling of the cast.
Description
Technical field
The invention belongs to foundryman's fever treatment facility technical field, be specifically related to a kind of grid-shaped airflow guiding device that is used for cooling large-sized annular cast.
Background technology
When adopting blower fan to force cooling large-sized foundry goods, act on the air-flow size of foundry goods and angle the cooling of foundry goods is played critical effect.At present, just with blower fan directly with airflow blow to foundry goods, foundry goods is forced cooling, the foundry goods inhomogeneous cooling is even, causes casting deformation, or forms stress and concentrate and crackle, and cooling effectiveness is lower.
Summary of the invention
The purpose of this invention is to provide a kind of grid-shaped airflow guiding device that is used for cooling large-sized annular cast, cooling large-sized annular cast has avoided foundry goods to concentrate and crackle because of the even distortion that causes of inhomogeneous cooling, stress quickly and evenly.
The technical solution adopted in the present invention is, a kind of grid-shaped airflow guiding device that is used for cooling large-sized annular cast, comprise that first connecting plate 1 of the annular that be arranged in parallel and second connecting plate, 3, the first connecting plates 1 of annular are connected by at least one equally distributed blade 2 with second connecting plate 3.
The two ends of described blade 2 are connected with second connecting plate 3 with first connecting plate 1 respectively by screw.
The width of described blade 2 is 200mm～800mm, highly is at least 500mm.
Described first connecting plate 1 is made up of at least four arc plates.
Described second connecting plate 2 is made up of at least four arc plates, and the quantity of this arc plate is identical with the quantity of the arc plate that constitutes first connecting plate 1.
Airflow guiding device of the present invention adopts grid shape blade, the control air-flow respectively and the angle that is blown into, the air-flow that blower fan is blown out acts on the foundry goods equably, guaranteed the evenly cooling fast of foundry goods, avoided distortion, the stress of foundry goods to concentrate and crackle, saved and occur repair welding that defectives such as crackle and distortion cause because of foundry goods and orthopedic etc. remedy operation, reduced cost.

Among the figure, 1. first connecting plate, 2. blade, 3. second connecting plate, 4. foundry goods, 5. blower fan.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of airflow guiding device provided by the invention can make air-flow act on foundry goods equably, makes evenly cooling fast of foundry goods.The structure of this device, comprise first connecting plate 1 of the annular that be arranged in parallel and second connecting plate 3 of annular, first connecting plate 1 is identical with the physical dimension of second connecting plate 3, first connecting plate 1 is connected by at least one blade 2 with second connecting plate 3, the two ends of blade 2 are connected with second connecting plate 3 with first connecting plate 1 respectively by screw, blade 2 circumferentially evenly distributes along connecting plate, and the width of blade 2 is 200mm～800mm, the height of 500mm≤blade 2＜foundry goods height.
According to the actual size of the annular cast that is cooled the quantity of blade 2 is set, the diameter that the internal diameter of first connecting plate 1 and second connecting plate 3 equals foundry goods 4 adds 300～1000mm.
For the ease of processing and manufacturing and transportation, first connecting plate 1 and second connecting plate 3 can be made arc plate, by blade 2 two arc plates are connected, constitute a grid shape part, during use, 4,6 or 8 grid shape parts are assembled into the airflow guiding device of an integral body according to the actual size of foundry goods.
As shown in Figure 3 and Figure 4, the foundry goods 4 of the heat treated annular of need is put into airflow guiding device, according to on-the-spot needs, unclamp with the screw that is connected the blade 2 and second connecting plate 3 with the screw of first connecting plate 1 connecting blade 2, angle Φ between blade 2 and foundry goods 4 normal orientation is adjusted in 0 °～60 ° scope, peripheral uniform four groups of blower fans 5 of airflow guiding device make the air outlet of blower fan 5 parallel with blade 2.Open blower fan 5, the cold wind that blower fan 5 produces, along blade 2 parallel being blown in the airflow guiding device, arrive the surface of foundry goods 4, foundry goods 4 is cooled off, and the cold wind that is blown into forms an air-flow on the screw stably at foundry goods 4 outer surfaces, can effectively improve the cooling atmosphere of foundry goods 4, realize the evenly cooling fast of foundry goods 4, reduce the distortion and the residual stress concentrations of foundry goods 4.
In the use,, can arrange 2 groups, 3 groups, 4 groups, 6 groups, 8 groups, 9 groups, 10 groups or 12 groups of blower fans in the periphery of airflow guiding device according to the size of foundry goods 4.
Adopt in the air blast cooling process, the heat radiation of cast(ing) surface mainly is made up of the heat exchange between heat radiation and foundry goods and the air.Under the temperature same case, the ratio that heat radiation reduces casting temperature is roughly the same, know according to the Fourier temperature funtion, can foundry goods uniform decrease in temperature, depend primarily on the heat exchange of foundry goods and air, the coefficient of heat transfer that just depends on foundry goods and air, and the coefficient of heat transfer of foundry goods and air depends on factors such as air themperature, air-flow velocity and airflow direction.Airflow guiding device of the present invention can be realized cast(ing) surface air velocity unanimity effectively in the foundry goods cooling procedure, thereby realizes that foundry goods evenly cools off.
