Abstract
The invention provides a positioning structure for a turbine blade blank, which can be used for solving the problems of non-uniform material flow and low material utilization ratio of a blank in a die forging process due to the absence of an effective positioning device for die forging of the conventional blank, can be used for effectively solving the problem of short service life caused by wear of a die, and contributes to lowering the production energy consumption and increasing the production efficiency. The positioning structure is characterized by comprising a forging die, wherein a material carrying table is arranged on the end part of the outer side of a leaf-crown-shaped cavity of a lower die forging module; a positioning lug is arranged on the top of a blank to be processed; the blank is arranged in the die cavity of the forging die; and the positioning lug of the blank is limited by using the material carrying table.
Description
Technical field
The present invention relates to the die forging technical field of turbine blade, be specially the location structure of turbine blade blank.
Background technology
Blank is a transition of bar and forging; the putting position of blank in mold cavity then has considerable influence to the final forming results of forging; in actual production, often can run into little with the size disparity of a collection of blank but the but larger situation of difference of the forging ' s block dimension after forging, this often since the location situation of blank in mold cavity determine.For the blade forging, especially for moving vane, corresponding location measure is not set when design blank and mould usually, cause blank Material Flow in forging process inhomogeneous, particularly for integral shroud, blade that the blade root torsional angle is larger, even the easy flow side of mold cavity add damping can not be fine play the blank locating effect, thereby cause stock utilization low; The inhomogeneities that flows of blank is so that the distribution of material in die cavity is relatively concentrated in addition, and resistance of deformation is large, causes die wear serious, greatly reduces the mold use life-span, also can cause the damage of forging equipment when serious; In addition, in the past owing to do not have blank location structure, operating personnel to require a great deal of time for the location of blank, cause the temperature drop of blank large, blank can not be at the higher situation compacted under of relative temperature, so that the processing fire is inferior many, energy consumption is large, and production efficiency is low.
Summary of the invention
For the problems referred to above, the invention provides the location structure of turbine blade blank, it can solve existing blank and cause the problem that blank Material Flow in die forging process is inhomogeneous, stock utilization is low because of the effective positioner of nothing in forging die, and can effectively reduce mould owing to the low problem in service life that wearing and tearing cause, reduce simultaneously energy consumption, enhance productivity.
Its technical scheme is such, it is characterized in that: it comprises forging die, be provided with in the integral shroud die cavity outboard end of described forging die lower module and put the material platform, the top of blank to be processed is provided with the location lug, and described blank is positioned in the described forging mould die cavity, its location lug expects that by described putting platform is spacing.
Adopt the location structure of turbine blade blank of the present invention, its beneficial effect is: it is simple in structure, can effectively position blank, thereby guarantee the uniformity of blank Material Flow in die forging process, afterwards improve stock utilization, and can effectively reduce the wearing and tearing of mould, thereby prolong die life; In addition, the present invention is convenient and practical, can greatly reduce the site operation personnel and place blank needed positioning time, also reduced simultaneously the temperature drop that the blank location produces, make blank at the higher situation compacted under of relative temperature, reach the purpose that reduces fire, reduces energy consumption, greatly improved produced on-site efficient.
