Description
Technical field
The present invention relates to mould applications, specially a kind of locomotive turbine disk split leaf mold.
Background technique
The turbine disk is mainly made of wheel disc matrix and several blades, wherein blade is along the circumferential direction set in qually spaced in
On the outer circumference surface of wheel disc matrix.The wheel disc matrix and blade of conventional turbine disk are the molding integral structure of integral cast, no
Only processing technology is complicated, and product qualified rate is lower, moreover, the turbine disk integrally will after wherein some or certain blade damages
It scraps, waste of raw materials is more serious.
Summary of the invention
It is an object of the invention to a kind of locomotive turbine disk split leaf molds, to solve existing technical problem.
To achieve the above object, the invention provides the following technical scheme: a kind of locomotive turbine disk split leaf mold, including
Multiple blade bodies, the bottom of multiple blade bodies are connected with tenon, and tenon is along the circumferential direction mounted in the tongue-and-groove of the turbine disk,
Multiple blade bodies include first surface and the second curved surface, and first surface and the second curved surface are connected, and the second curved surface is mounted on tenon
On head, the radian of first surface is 10 ° -20 °, and the radian of the second curved surface is 60 ° -45 °, is all provided on multiple blade bodies and tenon
There is bonding coat；
The front and rear sides of tenon are respectively equipped with front end face and rear end face, and front end face and rear end face are raised arc section, tenon
The left and right ends of head are respectively equipped with left side and right side, and left side is recess arc section, and right side is raised arc section.
Preferably, the high spot of the turbine disk and the side of multiple blade bodies fit.
Preferably, the material of bonding coat is silica-sol wash.
Compared with prior art, the beneficial effects of the present invention are:
Structure of the invention is novel in design, and independent die casting molding is respectively adopted in the turbine disk and blade, and not only finished product closes
Lattice rates is high, and blade is removably attached on wheel disc matrix by the clamping engagement of tenon and tongue-and-groove, when wherein some or
When certain blade damages, the blade of damage is only needed to change, raw material can be greatlyd save.
Detailed description of the invention:
Fig. 1: structural schematic diagram of the invention；
Fig. 2: the structural schematic diagram of blade mold of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution:
A kind of locomotive turbine disk split leaf mold, including multiple blade bodies 1, the bottom connection of multiple blade bodies 1
There is tenon 2, tenon 2 is along the circumferential direction mounted in the tongue-and-groove of the turbine disk 3, and multiple blade bodies 1 include first surface 6 and second
Curved surface 7, first surface 6 are connected with the second curved surface 7, and the second curved surface 7 is mounted on tenon 2, and the radian of first surface 6 is 10 °-
20 °, the radian of the second curved surface 7 is 60 ° -45 °, is equipped with bonding coat on multiple blade bodies 1 and tenon 2；
The front and rear sides of tenon 2 are respectively equipped with front end face 4 and rear end face 5, and front end face 4 and rear end face 5 are raised circular arc
Section, the left and right ends of tenon 2 are respectively equipped with left side 9 and right side 10, and left side 9 is recess arc section, and right side 10 is convex
Play arc section.
In the present embodiment, the high spot of the turbine disk 3 and the side of multiple blade bodies 1 fit.
In the present embodiment, the material of bonding coat is silica-sol wash.
In above embodiments, structure of the invention is novel in design, and structure of the invention is novel in design, and the turbine disk and blade are adopted respectively
It is formed with independent die casting, not only product qualified rate is high, but also blade is detachable by the clamping engagement of tenon and tongue-and-groove
Ground is assemblied on wheel disc matrix, when wherein some or certain blade damages, is only needed to change the blade of damage, can be saved significantly
Save raw material.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
