Description

Large-scale combustion engine guide vane design mould

Technical Field

The utility model relates to a design mould especially relates to a large-scale combustion engine guide blade design mould.

Background

The gas turbine is the heart of an energy power system, is the highest technical product of equipment manufacturing industry, and is called as the pearl on the imperial crown of the equipment manufacturing industry. The core parts of the hot end of the gas turbine, namely the turbine blade and the guide blade, have severe working conditions, strict metallurgical requirements and high dimensional precision requirements. The guide vane comprises an upper edge plate, a lower edge plate and a vane body, the difficulty of controlling the profile of the edge plates is always the precision casting of an investment mold, and a wax mold correction tool is usually used when a wax mold of the guide vane is produced. Each guide vane needs to be corrected for more than half an hour to be completely shaped. The calibration tool is expensive and usually only one calibration tool is manufactured. The production requirements can be completely met for single and test products. However, when mature batch type blades are produced, the single-pair correction tool seriously influences the production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model provides a large-scale combustion engine guide blade design mould has solved current when production guide blade wax matrix, uses the wax matrix to rectify the frock usually. Each guide vane needs to be corrected for more than half an hour to be completely shaped. The calibration tool is expensive and usually only one calibration tool is manufactured. The production requirements can be completely met for single and test products. But when the mature batch type blades are produced, the single pair of correction tools seriously influences the production efficiency.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a large-scale combustion engine guide blade design mould, which comprises a plate body, the material of plate body is the ya keli board, be equipped with on the plate body terminal surface and process left recess and the right recess that forms through the wax matrix size of blade of having stereotyped, left side recess and right recess setting are at the both ends of plate body, the width at left side recess is unanimous with the width at last flange top, the width at right side recess is unanimous with the width at lower flange top.

Preferably, the left groove and the right groove are rectangular in shape, and the bottom of one end, close to the left groove, of the left groove is flush with the bottom of one end, close to the right groove, of the right groove.

Preferably, the inner walls of the left groove and the right groove are provided with a left protective layer and a right protective layer which are made of metal materials. Through setting up left inoxidizing coating and right inoxidizing coating, can prevent in the use that the edge from producing the burr, influence in follow-up design.

Preferably, the width of one end of the plate body close to the right groove is flush with the bottom of one end of the right groove.

Preferably, the end face of one end of the plate body is provided with a plurality of fixing screw holes, and the plate body is connected with fixing bolts through the fixing screw holes and fixed on the positioning table.

Through the technical scheme, the utility model discloses beneficial effect: the shaping mould made through the simple ya keli of design, it is simple convenient to process to during the use, after extrusion wax matrix, detain the shaping mould on the blade, the recess blocks the flange, cools off to the wax matrix shrink end, and the flange size has just been fixed, and it is comparatively convenient to use, and has realized guide vane's batch production.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

According to shown large-scale combustion engine guide blade design mould in picture, the package rubbing board body 1, the material of plate body 1 is the ya keli board, be equipped with on 1 terminal surface of plate body and carry out left recess 2 and the right recess 3 that forms of processing through the wax matrix size of stereotyping the blade, left side recess and right recess 3 set up the both ends at plate body 1, left side recess 2's width is unanimous with the width on reason lamina top, right side recess 3's width is unanimous with the width at lower flange top, left side recess 2 is the rectangle with right recess 3's shape, left side recess 2 and right recess 3 are close to the bottom parallel and level of left recess 2 one end, be equipped with the metal material on left side recess 2 and the right recess 3 inner wall and make left inoxidizing coating 4 and right inoxidizing coating 5. Through setting up left inoxidizing coating and right inoxidizing coating, can prevent in the use that the edge from producing the burr, influence in follow-up design, the width of the one end of plate body 1 that is close to right recess 3 and the bottom parallel and level of right recess 2 one end, the one end terminal surface of plate body 1 is equipped with a plurality of fixed screw 6, plate body 1 is fixed on the location bench through fixed screw 6 connection fixing bolt

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
