Abstract
The invention relates to a method and a device for a thermal power generation steam cylinder integrated core bar fixed sand mold. The method comprises the following steps: firstly assembling a wooden mold, welding a first core bar in the position of a mold cavity, then forming a sand mold by pounding; sleeving a partitioning plate on a second core bar of a big core, welding the second core bar with the first core bar; adjusting the position of the partitioning plate, allowing the partitioning plate to press against the mold cavity, then pounding the sand of the big core; stripping the mold after the sand is completely hardened, with the sand of the mold cavity and the sand of the big core being interconnected and being taken out together. The method and the device have the advantages that the core in the mold cavity and the big core are connected together by using the welded core bars, thereby ensuring the accuracy and the completeness of the sand mold. During the process of taking out the sand mold, whether the core of the mold cavity is deformed or the strength is qualified are not taken into consideration.
Description
Technical field
The present invention relates to a kind of method and the device of fixing sand mold for thermal power generation cylinder disjunctor arbor.
Background technology
Steam turbine is a kind of is power with steam, and is the rotating machinery of mechanical power by the thermal energy of steam, is most widely used prime mover in modern thermal power plant.Steam turbine has the advantages such as single-machine capacity is large, efficiency is high, the life-span is long.
Cylinder is the shell of steam turbine, and its effect is separated the flow passage component of steam turbine and air, forms the steam chest closed, and ensures that steam completes the transfer process of energy in steam turbine inside, is installed with the parts such as nozzle box, dividing plate, diaphragm housing ring in cylinder; The pipeline such as be connected to admission, steam discharge outside cylinder, draw gas.Due to profile and the cavity structure complexity of Large-scale High-Pressure outer shell, wall thickness is thin, when large fuse molding, often die cavity break-off occurs, or large fuse and cavity positions generation relative movement occur, cause whole shell to be cast unsuccessfully.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of this invention is to provide a kind of method and the device of fixing sand mold for thermal power generation cylinder disjunctor arbor, ensureing integrality and the accuracy of sand mold.
For achieving the above object, the present invention is achieved through the following technical solutions:
Fix a method for sand mold for thermal power generation cylinder disjunctor arbor, comprise the following steps:
1) first that die model group is good, at cavity positions welding arbor one, then carry out Chong sand mold;
2) by dividing plate through on the arbor two of large fuse, arbor two and arbor one weld together;
3) adjust partition position, make dividing plate be resisted against on die cavity, then carry out the Chong sand of large fuse;
4), after sand hardens completely, molding, together with the sand of die cavity is linked as with the sand of large fuse, trips out together.
Fix a device for sand mold for thermal power generation cylinder disjunctor arbor, comprise arbor one, arbor two, large fuse, dividing plate, die cavity, imbed arbor one in die cavity, imbed arbor two in large fuse, arbor one is fixedly connected with arbor two, and junction is provided with dividing plate.
Described dividing plate is cystosepiment.
Described arbor one is T-shaped structure with arbor two, and arbor one forms I-shape construction after welding with arbor two.
Compared with prior art, the invention has the beneficial effects as follows:
Directly utilize the arbor of welding fabrication that the fuse in die cavity and large fuse are linked together, ensure that accuracy and the integrality of sand mold.In the process of sand mold molding, without the need to considering whether die cavity fuse is out of shape, and whether intensity reaches requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-arbor one 2-large fuse 3-die cavity 4-dividing plate 5-arbor two.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in detail, but it should be noted that enforcement of the present invention is not limited to following embodiment.
See Fig. 1, a kind of method of fixing sand mold for thermal power generation cylinder disjunctor arbor, comprises the following steps:
1) first that die model group is good, at die cavity 3 position welding arbor 1, then carry out Chong sand mold;
2) by the arbor 25 of dividing plate 4 through large fuse 2, arbor 25 and arbor 1 weld together;
3) adjust dividing plate 4 position, make dividing plate 4 be resisted against on die cavity 3, then carry out the Chong sand of large fuse 2;
4), after sand hardens completely, molding, together with the sand of die cavity 3 is linked as with the sand of large fuse 2, trips out together.
The device of sand mold is fixed for thermal power generation cylinder disjunctor arbor, comprise arbor 1, arbor 25, large fuse 2, dividing plate 4, die cavity 3, imbed arbor 1 in die cavity 3, in large fuse 2, imbed arbor 25, arbor 1 is fixedly connected with arbor 25, and junction is provided with dividing plate 4.
Wherein, dividing plate 4 is cystosepiment.Arbor 1 and arbor 25 are T-shaped structure, and arbor 1 forms I-shape construction after welding with arbor 25.
The present invention directly utilizes the arbor of welding fabrication that the fuse in die cavity and large fuse are linked together, and ensure that accuracy and the integrality of sand mold.In the process of sand mold molding, without the need to considering whether die cavity fuse is out of shape, and whether intensity reaches requirement.
