The invention aims to solve the technical problem of providing an integral processing method of a rudder ball sealing plate aiming at the defects of the background technology, the rudder ball sealing plate is not spliced by a plurality of outer plates, and a single plate design is adopted, so that the processing precision is high, the efficiency is high, the cost is low, and the service life of the single sealing plate is greatly prolonged.
The invention adopts the following technical scheme for solving the technical problems:
the integral processing method of the rudder bulb sealing plate is characterized in that: the method comprises the following steps:
step 2, heating the circular blanking plate after lofting and unfolding;
step 3, performing die assembly stamping on the heated blanking plate by using an oil press;
and 4, rounding off after the punching is finished.
Further, in the step 1, the temperature of the part is heated to 500 ℃ and not more than 600 ℃ once.
Further, in step 3, an oil press with a pressure of 2500 tons is selected as the oil press.
Further, in step 3, the mold closing and pressing time is 10 minutes.
Further, in step 4, the error range of rounding is plus or minus 0.5 mm.
Compared with the prior art, the invention adopting the technical scheme has the following technical effects:
the rudder ball sealing plate provided by the invention does not need to be spliced by a plurality of outer plates, and adopts a single plate design, so that the processing precision is high, the efficiency is high, the cost is low, and the service life of a single sealing plate is greatly prolonged.
