The position guiding pin post that its can be controlled movable is provided with support block.
The upper lid is provided with the guide pin bushing being engaged with guide pillar, and guide pillar is placed in guide pin bushing.
The guide pillar is two, is symmetricly set on a diagonal of base, and be fixed on base.
Second bucket support block is provided with the groove for being offered on the base of the side of position guiding pin post and setting fixed block,
Fixed block is placed in groove, and the second bucket support block is fixed by fixed block.
The antidote of mould is corrected on a kind of multi-joint Blade roughcast exhaust side, is comprised the following steps：
Step one, when furnace temperature is at≤700 DEG C, blade is put into high-temperature box type electric furnace roaster, rise furnace temperature to 1000
It is incubated after~1100 DEG C；
Step 2, the blade heated is taken out and is put into the base of correction mould, leading edge is put downwards, after being well placed
Promote position guiding pin post to make the second bucket support block against blade, fixed block is fixed, blade is positioned and is fastened completely；
Step 3, upper lid is fixed on hydraulic press, corrected using pressure；
Step 4, hydraulic press compression leg backhaul unloading pressure, while fixed block is pulled open in lid motion upwards on driving, movement
With the second bucket support block, the part corrected is taken out, correction is completed.
In the step one, soaking time is 1h.
In the step 3, it is that pressure is 10MPa to carry out correction using pressure, and the dwell time is 40~60s.
Compared with prior art, multi-joint Blade roughcast exhaust side correction mould of the invention by the first bucket support block and
Second bucket support block clamps blade, is corrected by upper lid and bottom seat, and this correction mould structure design is simple, operation side
Just, efficiency high, the influence of human factor, the casting one through correction are avoided to the correcting process that multi-joint blade is vented side linearity
Cause property is very good, once corrects qualification rate and can reach more than 90%.
Further, two guide pillars of the invention are symmetricly set on a diagonal of base, it is ensured that base and upper
The overlapping positions of lid, improve positioning precision.
Using the antidote of present invention correction mould, blade is heated, then the blade after heating is put into correction mould
In, corrected by pressure, about 1 minute single-piece improvement time, it is corrected efficiency and improves 10 times, and is vented suffered by side
Pressure is uniform, can be widely popularized and applied in the exhaust side straightening application of other multi-joint Blade roughcasts.
