Example Embodiment

[0015] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0016] Such as figure 1 As shown, the air flow guiding device provided by the present invention can make the air flow evenly act on the casting, and make the casting uniform and rapid cooling. The structure of the device includes an annular first connecting plate 1 and an annular second connecting plate 3 arranged in parallel. The first connecting plate 1 and the second connecting plate 3 have the same structural size. The first connecting plate 1 and the second connecting plate The plate 3 is connected by at least one blade 2, and the two ends of the blade 2 are respectively connected to the first connecting plate 1 and the second connecting plate 3 by screws. The blades 2 are evenly distributed along the circumferential direction of the connecting plate, and the width of the blade 2 is 200mm~ 800mm, 500mm≤ height of blade 2< height of casting.

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 [0001] The invention belongs to the technical field of casting heat treatment equipment, and in particular relates to a grid-shaped airflow guiding device for cooling large annular castings. Background technique [0002] When a large casting is forced to be cooled by a fan, the size and angle of the airflow acting on the casting play a key role in the cooling of the casting. At present, only a fan is used to directly blow the airflow to the casting for forced cooling of the casting. The cooling of the casting is not uniform, resulting in deformation of the casting, or the formation of stress concentration and cracks, and the cooling efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a grid-shaped airflow guiding device for cooling large annular castings, which can quickly and uniformly cool large annular castings, and avoid deformation, stress concentration and cracks of castings caused by uneven cooling....
