Abstract
The invention provides a method for quickly detecting the offset amount of a blade forging die. The offset amount of the blade forging die can be quickly detected by adopting the method. The method is characterized in that a detection module is respectively inlayed in flat parting surface regions at two end portions of an upper die and a lower die of the blade die, offset grooves symmetrically matched with the surfaces are respectively arranged on the detection modules, the upper die and the lower die are installed on a device, metal detection test blocks are placed in the offset grooves of the lower die, a device stroke is adjusted, the upper die and the lower die are closed up, the metal detection test blocks are filled in cavities of the offset grooves in the closing-up process under the acting force of the upper die and the lower die, then the device returns, the metal detection test blocks are taken out, and the die offset amount can be obtained by directly measuring the offset amounts of the surfaces of the metal detection test blocks.
Description
Technical field
The present invention relates to the detection field that hot-working is forged, especially relate to turbine blade hot forging detection field, be specially a kind of method of fast detecting blade forging mould offsetting amount.
Background technology
In blade hot forging forming process, mold work environment is severe, be subject to the effect of repetition thermal load and mechanical load, and the impact of large this design feature of the blade profile distortion that is subject to turbine blade, make the stressed more complicated of blade forging mould, in forging molding process, huge forming force must cause mould to be subject to larger side force, causes producing inconsistent phenomenon between upper and lower mould.In actual production because blade construction is complicated, the blade profile distortion of blade is larger, simultaneously the out-of-shape such as blade root, boss, integral shroud cause mould offsetting amount cannot be from forging direct-detection, because opportunity has a strong impact on the judgement of testing staff to mould offsetting amount, thereby the judgement of impact to forging ' s block dimension precision, becomes the difficult problem that long-term puzzlement blade hot-working die-forging forming detects.
Summary of the invention
For the problems referred to above, the invention provides a kind of method of fast detecting blade forging mould offsetting amount, it can fast detecting blade forging mould offsetting amount.
Its technical scheme is such, it is characterized in that: at the patrix of blade mold, the straight land areas at the both ends of counterdie is insert detection module respectively, on described detection module, offer respectively the offsetting groove of the symmetrical coupling of profile, by described patrix, counterdie is installed on equipment, in the offsetting groove of described counterdie, place metal detection test block, adjust device travel, described patrix and counterdie are carried out to matched moulds, in metal detection test block described in described matched moulds process, be subject to described patrix, the acting force of counterdie is filled along the die cavity of described offsetting groove, then equipment backhaul, take out described metal detection test block, directly measure described metal detection test block profile offsetting amount and can obtain mould offsetting amount.
It is further characterized in that:
Described offsetting groove is L shaped groove, and the groove face of described L shaped groove is arc surface;
Described metal detection test block is lead;
Described metal detection test block is the iron block that is heated to forging temperature.
The method of a kind of fast detecting forging process of the present invention Leaf mould offsetting amount, its beneficial effect is: it forges and presses by the metal detection test block in the offsetting groove of the symmetrical coupling of the profile to the detection module of the straight land areas insert at forging die upper die and lower die both ends, the offsetting amount of the metal detection test block profile after forging and pressing by measurement judges that the offsetting of mould measures, its method is simple, and testing result is intuitively accurate; Because the offsetting groove of upper die and lower die is the L shaped groove of the symmetrical coupling of profile, and the groove face of L shaped groove is arc surface, so is deformed into the simple L shaped right cylinder of cross section structure after metal detection test block forging and stamping, therefore more improved the convenience that mould offsetting amount detects; In addition, the inventive method can detect the assembling offsetting amount of forging die patrix and counterdie, can detect again the offsetting amount of forging die under stress, thereby highly versatile.

Embodiment
Specifically describe the implementation process that adopts the inventive method to detect blade forging die assembly offsetting amount below:
See Fig. 2～Fig. 4, patrix 1 at blade mold, the straight land areas 4 at the both ends of counterdie 2 is installed with respectively detection module 6, on detection module 6, offer the L shaped offsetting groove 3 of the symmetrical coupling of profile, and the groove face of L shaped offsetting groove is arc surface, by patrix 1, counterdie peace 2 is loaded on equipment, the interior placement lead 5 of offsetting groove 3 at counterdie 2, adjust device travel, patrix 1 and counterdie 2 are carried out to matched moulds, in matched moulds process, lead 5 is subject to patrix 1, the acting force of counterdie 2 carries out filling molding along the die cavity of offsetting groove 3, then equipment backhaul, take out the lead 5 after moulding, after direct measurement moulding, the profile offsetting amount of lead 5 can obtain the assembling offsetting amount of mould.In Fig. 4, d is the offsetting amount of patrix and counterdie.
While adopting offsetting amount under stress of forging mold that the inventive method detects blade, only lead need to be replaced with to the iron block that is heated to forging temperature, iron block is positioned in the offsetting groove 3 of counterdie 2, make iron block synchronize forging molding with blade forging, thereby then the iron block after moulding is carried out to profile measurement and accurately detect the offsetting amount of forging molding mould under stress.
