Abstract
The utility model discloses a rudder blade molding frame. A square frame is formed by longitudinally arranging templates (7), in the templates (7), two end points at the upper edge (8) of the longest template (7) in the middle are set to be a first reference point (3) and a second reference point (4), the heights of the first reference point (3) and the second reference point (4) are 0mm and -3mm respectively, four end points at the upper edge of the template (7) at two ends are a first calibration point (1), a second calibration point (2), a third calibration point (5) and a fourth calibration point (6) respectively, the heights of which are -10 to -15mm, -10 to -15mm, -7 to -12mm and -11 to -16mm respectively. In the utility model, the molded left and the right strings are symmetrical along a middle shaft surface, so that the use precision of the rudder blade is guaranteed.
Description
Technical field
The utility model relates to a kind of rudder blade moulding moulding bed.
Background technology
Why boats and ships can navigate by water, and are its motive power through screw to the shunting guide effect to water of the promotion of water and rudder blade, the navigation direction of decision boats and ships.The size of motive power and screw has determined the speed of ship's navigation, and rudder blade structural member port and starboard is along the quality of axis in the face of claiming, with the precision that influences the boats and ships guiding.
For this large-sized structural parts of rudder blade (weighing 40 tons-more than 200 ton) is carried out, rudder blade manufacturing factory all uses the prefabricated rudder blade moulding of prestrain method moulding bed, will on moulding bed, manufacture rudder blade then.
Yet in the manufacturing process of reality, rudder blade occurs not with the phenomenon of axis through regular meeting, thereby influence the guiding service precision of rudder blade in the face of claiming according to ideal designs.
The utility model content
The technical scheme to be solved of the utility model provides a kind of rudder blade moulding moulding bed, and it can guarantee the dimensional accuracy of rudder blade.
In order to solve above-mentioned technical problem; The technical scheme of the utility model is: a kind of rudder blade moulding moulding bed; Constitute square frame-like by vertical arrangement of template; The top edge of template is an arc shaped, and the top edge of template arc shaped constitutes the arc-shaped concave of rudder blade moulding moulding bed, in said template; Two end points of the template top edge that the centre is the longest are set at first datum mark and second datum mark; First datum mark, the second datum mark height be respectively be 0 and-3mm, four end points of the top edge of two Side Templates are respectively first calibration point, second calibration point, the 3rd calibration point and the 4th calibration point, it highly is respectively :-10～-15mm ,-10～-15mm ,-7～-12mm and-11～-16mm.
The height of said first calibration point, second calibration point, the 3rd calibration point and the 4th calibration point is respectively :-13mm ,-13mm ,-9mm and-13mm.
The change in size of the utility model rudder blade moulding moulding bed after with the rudder blade moulding considered in the scope that influences the rudder blade precision; Several end points on the axial plane in the rudder blade are reserved certain scope; The left and right sides string that has guaranteed the rudder blade after the moulding is faced title along axis, guarantees the service precision of rudder blade.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of rudder blade.
Fig. 2 is the structural representation of the utility model rudder blade moulding moulding bed.
The specific embodiment
As shown in Figure 1, perfect condition A, B, C, D, E, 6 points of F have constituted axial plane in the rudder blade level, and the horizontal axis that the larboard 9, starboard 10 that makes rudder blade forms with A, B, C, D, E, F is in the face of claiming, make the use of the rudder blade state of realizing ideal.
But tend to occur E point and all the other point not at grade at the rudder blade that actual moulding bed is made, rudder blade is occurred with axis in the face of claiming, thereby influence the guiding service precision of rudder blade.
Put the corresponding point that goes out of A, B, C, D, E, F and be respectively first datum mark 3 and second datum mark 4, the 3rd calibration point 5 and the 4th calibration point 6 on first calibration point 1 shown in Figure 2, second calibration point 2, the intermediate die plate on the rudder blade moulding moulding bed of the utility model with on the rudder blade.
In the middle of wherein first datum mark 3, second datum mark 4 of the longest template 7 top edges 8 highly be respectively 0 and-3mm, the altitude range of first calibration point 1, second calibration point 2, the 3rd calibration point 5 and the 4th calibration point 6 is respectively :-10～-15mm ,-10～-15mm ,-7～-12mm and-11～-16mm.
Can be respectively the height of setting first calibration point 1, second calibration point 2, the 3rd calibration point 5 and the 4th calibration point 6 is :-13mm ,-13mm ,-9mm and-13mm.The affected like this finished product rudder blade that comes out; Basically can make A, B, C, D, E, F6 point in the rudder blade level on the axial plane; Make larboard 9, the starboard 10 of rudder blade face title with the horizontal axis that A, B, C, D, E, F form; Reach desirable effect, make rudder blade reach desirable user mode in ship's navigation.
The foregoing description limits the utility model never in any form, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in the protection domain of the utility model.
