Abstract
The invention relates to a forming method for producing hydroelectric blades without a sand box and a core box, which adopts full pattern direct forming, and comprises the following steps: respectively casting on the two vertical surfaces of a blade; completing casting of the outside curved surface of the full pattern of the blade, and after molding sand completely hardens, casting the inside curved surface of the full pattern of the blade; and adopting vertical pouring. Compared with the prior art, the invention has the beneficial effects that a sand box tool and a core box are not used, and overturn is not needed in the whole production process, thereby improving the dimensional accuracy of the blade; and the operation is convenient, a large hoisting machine is not needed, and the production is safe.
Description
Technical field
The present invention relates to a kind of system type method of producing hydroelectric blades, is a kind of system type method that does not adopt sandbox and core box to produce blade.
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.
Summary of the invention
The purpose of this invention is to provide a kind of system type method of not having sandbox, no core box production hydroelectric blades, the direct full pattern system type of this method, two facade branches of spoon of blade are pounded, 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.
For achieving the above object, the present invention is achieved through the following technical solutions:
The system type method that no sandbox, no core box are produced hydroelectric blades, this method may further comprise the steps:
1) the blade full pattern is placed on the molding sand plane of strickling, forms two side elevations;
2) the blade full pattern is fixed;
3) outside the blade full pattern on the N-Side surf with the molding sand reality of pounding;
4) treat 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;
5) adopt during blade full pattern inner curve system type the core box frame that blade full pattern inner curve is fenced up, fill with molding sand;
6) treat inner curve molding sand sclerosis after, form core; The inner curve core is removed, with the molding of blade full pattern;
7) working face of both sides core is repaiied type, swabbing, oven dry;
8) the inner curve core is retracted, following core waits to be cast.
Compared with prior art, the invention has the beneficial effects as follows:
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 that Fig. 1, Fig. 2 do not have the system type method of sandbox, no core box production hydroelectric blades, this method may further comprise the steps:
1) at first in melt pit, scrapes out-of-plane with molding sand;
2) the blade full pattern is placed on the molding sand plane, forms two side elevations;
3) because blade full pattern wall is thinner, and be hyperboloid, be difficult to put surely that in blade full pattern both sides sand block plate 3 is set, the sand block plate had both played the effect that strengthens full pattern intensity, had played the sand block effect again;
4) also need the blade full pattern is fixed during the system type, with keep size accurately; By on blade full pattern inner curve 6, supporting,, avoid that the full pattern displacement causes scale error in the ramming process with the iron pipe fixation of supporting with iron pipe;
5) outside the blade full pattern on the N-Side surf 4 with the facing sand reality of pounding, floor sand adopts alkalescent phenol resin sand;
6) treat that sand mold hardens fully after outer N-Side surf 4 system of pounding of blade full pattern is finished, the system of pounding blade full pattern inner curve;
7) adopt during blade full pattern inner curve 6 system types core box frame 2 that blade full pattern inner curve 6 is fenced up, guaranteeing has enough mold thicknesses, fills with molding sand;
8) treat molding sand sclerosis after, form core 1; Then core is hung away, so that shift out the blade full pattern;
9) with the molding of blade full pattern;
10) working face of both sides core is repaiied type, swabbing, oven dry;
11) the inner curve core is retracted, stuck with model during following core, guarantee that the size of blade is accurate, bury case, wait to be cast.
This 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.
