Abstract
A die for spinning an air inlet set of a marine fan is composed of a main shaft connecting flange (1), an air inlet spinning shaft sleeve (2), an air inlet spinning flange (3), an air inlet tail top die (4), a centering small shaft (5) and a tail top shaft (6). The die for spinning the air inlet set of the marine fan is low in cost and convenient to detach.
Description
Technical Field
The utility model relates to the technical field of design and manufacture of spinning dies.
Background
In the past, the manufacturing of the air inlet group of the marine fan is of a splice welding structure, the appearance is poor after welding by the method, the manufacturing time is long, and the surface of the welded air inlet group is not smooth, so that the inlet air flow resistance of the marine fan is increased, the pneumatic efficiency of the marine fan is reduced by 0.5-0.8%, and the energy consumption of the marine fan is increased.
Disclosure of Invention
The utility model aims to overcome the technical defects and provides the die for spinning the air inlet set of the marine fan, which is low in cost and convenient to detach.
In order to achieve the purpose, the technical scheme adopted by the utility model is that the device consists of a main shaft connecting flange (1), an air inlet spinning shaft sleeve (2), an air inlet spinning flange (3), an air inlet tail top die (4), a centering small shaft (5) and a tail top shaft (6); the device is characterized in that a main shaft connecting flange (1), an air inlet spinning shaft sleeve (2) and an air inlet spinning flange (3) are positioned through a spigot in sequence and are screwed and connected into an integral structure by bolts; the air inlet tail top die (4) and the tail top shaft (6) are connected through bolts, and a centering small shaft (5) is arranged at the center of the installation side of the tail top shaft (6) and the air inlet tail top die (4).
By adopting the technical scheme, compared with the prior welding manufacturing method, the manufacturing cycle is greatly saved, the working efficiency is improved, and the flow passage of the air inlet group of the ship fan manufactured by spinning is smooth.
Drawings
FIG. 1 is a schematic diagram of a die for spinning a marine fan air inlet set;
FIG. 2 is a schematic view of the tail top of a die for spinning a marine fan air inlet set;
1. a main shaft connecting flange; 2. the air inlet is spun with the axle sleeve; 3. a flange for spinning an air inlet; 4. an air inlet tail top die; 5. centering the small shaft; 6. and a tail top shaft.
Description of the embodiments
The utility model is further described below with reference to the accompanying drawings.
A spinning die for an air inlet set of a marine fan is composed of a main shaft connecting flange (1), an air inlet spinning shaft sleeve (2), an air inlet spinning flange (3), an air inlet tail top die (4), a centering small shaft (5) and a tail top shaft (6); the device is characterized in that a main shaft connecting flange (1), an air inlet spinning shaft sleeve (2) and an air inlet spinning flange (3) are positioned through a spigot in sequence and are screwed and connected into an integral structure by bolts; the air inlet tail top die (4) and the tail top shaft (6) are connected through bolts, and a centering small shaft (5) is arranged at the center of the installation side of the tail top shaft (6) and the air inlet tail top die (4). By adopting the scheme, the surface of the air inlet set of the spinning marine fan is very smooth, the air inlet spinning shaft sleeve (2) and the air inlet spinning flange (3) are completely consistent with the arc surface of the air inlet set designed by the drawing, so that the arc size of the air inlet set of the spinning marine fan is ensured to completely meet the drawing requirement, and the situation that the size is inconsistent due to deformation of the air inlet set manufactured by adopting a welding method in the past is thoroughly avoided; meanwhile, the spinning die is low in cost, simple in structure and very convenient to detach, install and use.
Therefore, the die for spinning the air inlet set of the marine fan is low in cost and convenient to detach.
