Abstract

The utility model provides a positioning structure of turbine blade blank. The positioning structure solves the problems that material flow is uneven and the utilization rate of materials is low in the die forging process of existing blank due to lack of an effective positioning device, can effectively reduce the problem that due to abrasion, service life of a die is short, meanwhile reduces production energy consumption, and improves production efficiency. The positioning structure is characterized by comprising a forging die. A material placement platform is arranged on the end portion of the outside of an integral-tip-shroud cavity of a lower module of the forging die, a positioning lug is arranged at the top of the to-be-machined blank, the blank is placed in the cavity of the forging die, and the positioning lug is limited by the material placement platform.

Description

A kind of location structure of turbine blade blank

Technical field

The utility model relates to the die forging technical field of turbine blade, is specially a kind of location structure of turbine blade blank.

Background technology

Blank is a transition of bar and forging; the putting position of blank in mold cavity has considerable influence to the final forming results of forging; but often can run into little with the size disparity of a collection of blank in actual production the but larger situation of difference of the forging ' s block dimension after forging, location situation in mold cavity determines due to blank often for this.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 mobile inhomogeneities of blank makes the distribution of material in die cavity 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, owing to there is no the blank location structure, operating personnel required a great deal of time for the location of blank in the past, 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 utility model provides a kind of location structure of turbine blade blank, it can solve existing blank and cause because of the effective positioner of nothing the problem that blank Material Flow in die forging process is inhomogeneous, stock utilization is low in forging die, and can effectively reduce mould due 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 described forging mould die cavity, its location lug expects that by described putting platform is spacing.

Adopt the location structure of the utility model turbine blade blank, 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 extend die life; In addition, the utility model is convenient and practical, can greatly reduce the site operation personnel and place blank needed positioning time, also reduced simultaneously the temperature drop of blank location generation, 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.
