Abstract
The invention relates to an integral processing method of a rudder bulb sealing plate, which comprises the following steps: step 1, opening the mold: designing a mould with a corresponding shape according to the shape of the rudder ball sealing plate; 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. 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 machining precision is high, the efficiency is high, the cost is low, and the service life of a single sealing plate is greatly prolonged.
Description
Technical Field
The invention belongs to the field of rudder ball processing, and particularly relates to an integral processing method of a rudder ball sealing plate.
Background
The rudder ball is used as a component on the rudder blade, and can play a role in counteracting propeller vortex, thereby reducing the generation of cavitation bubbles and further reducing the navigation resistance of the ship.
As shown in fig. 1, a conventional rudder ball sealing plate 1 is designed as nine outer plates, and the ball processing is performed in eight sample boxes. The processing workload is huge, and the precision is not high after the processing is finished.
Disclosure of Invention
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.
