Abstract
The utility model relates to a device for producing hydropower blade molding without a molding box or a core box. The device is characterized in that a hydropower blade sample, a core box frame, a sand core and sand blocking plates are included; the two sides of the hydropower blade sample are fixed through the sand blocking plates; molding sand is arranged on the curved surface of the outer side of the hydropower blade sample; and the curved surface of the inner side of the hydropower blade sample is fixed through the core box frame and the sand core. Compared with the prior art, the utility model has the benefits of convenience in operation, no requirement of large-scale crane, and safety of production.
Description
Technical field
The utility model relates to a kind of production hydroelectric blades system type device, is that a kind of sandbox and core box of not adopting produced blade system type device.
Background technology
Blade is the hyperboloid platy structure, when casting, has selected the flange process program of vertical upright casting up.The advantage of this process program be the thickest flange up, help forming top-down consecutive solidification condition, the feeding situation is good.So just can regard blade as a tabular curved body that is standing, the molding when this special structure is not easy to general formative method and repair type, so the general moulding of pounding of crouching, the process program of the upright casting of overturning again of adopting during the system type.Because spoon of blade is irregular, area is big, so adopt the old technology scheme must be designed to molding sand case instrument, work such as moulding mould assembling, lifting, upset is all caused very big difficulty, for large-scale blade even can't lift by crane.
The utility model content
The purpose of this utility model provides a kind of no sandbox, no core box is produced hydroelectric blades system type device, and is easy to operate, do not need large-scale lifting machine, production safety.
For achieving the above object, the utility model is achieved through the following technical solutions:
No sandbox, no core box are produced hydroelectric blades system type device, comprise hydroelectric blades full pattern, core box frame, core, sand block plate, hydroelectric blades full pattern both sides are fixed by the sand block plate, the outer N-Side surf of hydroelectric blades full pattern is provided with molding sand, and hydroelectric blades full pattern inner curve adopts core box frame and core that hydroelectric blades full pattern inner curve is fixed.
Compared with prior art, the beneficial effects of the utility model are:
The direct full pattern system type of this method, two facade branches of blade are pounded, and do not use the sandbox instrument, do not adopt core box, and need not overturn in the whole process of production, thereby improve the dimensional accuracy of blade, and easy to operate, do not need large-scale lifting machine, production safety.
Description of drawings
Fig. 1 is the three-dimensional structure diagram that no sandbox, no core box are produced hydroelectric blades system type;
Fig. 2 is the state diagram that no sandbox, no core box are produced hydroelectric blades system type.
Among the figure: the outer N-Side surf 5-rising head 6-blade full pattern inner curve of 1-core 2-core box frame 3-sand block plate 4-blade full pattern
The specific embodiment
See Fig. 1, Fig. 2, no sandbox, no core box are produced the system type device of hydroelectric blades, and hydroelectric blades full pattern vertically-arranged is on melt pit, and both sides are fixing by sand block plate 3, the hydroelectric blades full pattern outward on the N-Side surf 4 with the molding sand reality of pounding; Hydroelectric blades full pattern inner curve 6 adopts core box frame 2 that blade full pattern inner curve is fenced up, with core 1 reality of pounding.
Production method adopts directly system type of full pattern, and two facade branches of blade are pounded, and treats that molding sand hardens fully after the outer N-Side surf system of pounding of blade full pattern is finished, the system of pounding blade full pattern inner curve; Adopt vertical pouring.Do not use the sandbox instrument, do not adopt core box, need not overturn in the whole process of production, thereby improved the dimensional accuracy of blade, and easy to operate, do not need large-scale lifting machine, production safety.
