Embodiment Construction

[0022] Below, we will further elaborate on the manufacturing method of the connected rudder arm deflector of the present invention in combination with the accompanying drawings and specific embodiments, but this should not limit the protection scope of the present invention.

[0023] The linear section design of the deflector and the setting of the fan-shaped plate seam line:

[0024] Let’s first talk about designing the linear section of the diversion device so that the curvature of the bottom of the hull in the stern area is connected with the drip-shaped rudder arm. According to the arc transition between the curvature surface of the ship’s bottom and the rudder arm, select a suitable arc Profile type value points to ensure the correctness of the connecting line type.

[0025] The method for obtaining the positioning value of the linear section of the above-mentioned diversion device is: spread out in a fan shape at both ends of the rudder arm and rudder bearing with the ce...

Abstract

The invention relates to a method for manufacturing a connecting type rudder arm flow guide device, which comprises the following steps of: designing the linear profile of a flow guide device and setting a fan-shaped plate seam line; blanking and marking; transversely extruding, bending and deforming by utilizing an oil press; baking by utilizing water and fire to achieve longitudinal and curve disadvantage bending deformation; and checking and processing allowance. The method of the invention can ensure the linear accuracy of the flow guide device, shorten the production period, reduce the production cost and ensure that the production design can be matched with the processing manufacture method of a production department and the connection of the moulded rudder arm of the flow guide device and a ship body has integrity.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a manufacturing method of a rudder arm connection type flow guiding device mounted on a ship. Background technique [0002] In ship construction, the role of the ship's rudder arm guide device is to obtain a uniform wake field and convert resistance into power, thereby increasing the speed of the ship. It is the first time for our company to encounter a certain type of rudder arm connection type deflector. This type of ship adopts a closed connection between the bottom of the hull and the rudder arm. Due to the linear shape of the bottom area There are large vertical and horizontal irregular curvature surfaces connected with the drip line of the rudder arm. The setting and expansion of the deflector plate seam in the production design has certain technical requirements and difficulties, and various factors need to be considered. Especially in the setting of the plate seam line, it is necessary to...
