(3.2) the rudder blade line style provided according to rudder blade structure figure produces rudder blade template moulding bed 8, as shown in Figure 4, and ensure the rigid requirements of moulding bed 8, moulding bed 8 is laterally laid larboard outside plate 1, and larboard outside plate 1 is fixing with the laminating of code plate with moulding bed 8, between larboard outside plate 1 and moulding bed 8, gap should be less than 1mm；
(3.3) rudder blade design structure diagram is installed, larboard outside plate 1 is installed horizontal baffle 3, vertical partition plate 4, upper sealing plate 5, lower shrouding 6 and lagging edge tail liner plate 7, guide margin aside-liner, when horizontal baffle 3 and vertical partition plate 4 are installed on the basis of horizontal baffle 3, the installation of lagging edge tail liner plate 7 should ensure that level, level is made simultaneously, lower shrouding 5, the middle section line of 6 also carries out labelling with sample punching, in guarantee, lower shrouding 5, 6 and horizontal plane, on, lower shrouding 5, the middle section line of 6 is parallel and is in same level, and with in the method guarantee arranging messenger wire pendant 14, lower shrouding 5, the perpendicularity of 6, i.e. should ensure that and be in same vertical plane with its ground sample on the ground；
(3.4) horizontal baffle 3, vertical partition plate 4 are welded on larboard outside plate 1, and carry out the welding between each dividing plate, then upper and lower shrouding 5,6 and lagging edge tail liner plate 7, guide margin aside-liner are welded on larboard outside plate 1；
(3.5) after step (4) starboard outside plate 2 is welded on larboard outside plate 1, forms overall rudder blade, starboard outside plate 2 and larboard outside plate 1 by upper sealing plate 5, lower shrouding 6 line place, middle section horizontal plane on the basis of be symmetrical arranged；
In the present embodiment, in step (4), rudder stock 13 uses with rudder blade and is welded to connect, and concrete welding step is as follows:
(4.1) on upper sealing plate 5, horizontal baffle 3, rudder stock central point O is made respectively, with rudder stock central point O as the center of circle, draw the cutting circle 9 with rudder stock 13 equal diameter, upper sealing plate 5 draws simultaneously and cuts circle 9 is concentric but diameter is more than the inspection round 10 of cutting circle 9 diameters；
(4.2) on the upper sealing plate 5 of rudder blade, formation rudder stock is removed in material cutting in cutting circle 9 according to rudder blade structure figure and scurry into hole, it is ensured that upper sealing plate 5 rudder head scurries into center and the rudder stock center superposition in hole, and deviation is not more than 0.5mm；
(4.3) rudder stock 13 is supported by bracing frame 11, and its front end (i.e. the conical surface (or claiming slightly face) end) is scurried into rudder stock scurry in hole, and ensure on rudder stock 13 that the extended line for the centrage of the keyway connected with rudder base intersects with upper sealing plate centrage, to ensure the accurate installation direction of this keyway；
(4.4) on the basis of the upper sealing plate 5 of rudder blade, correcting rudder stock 13 integral level with horizon rule, in 1m length, deviation is not more than 0.1mm；Measure the perpendicularity of correction rudder stock 13 fore-and-aft direction and rudder blade upper sealing plate 5 with big square, in 1m length, deviation is not more than 0.1mm；
(4.5) center of correction rudder stock 13 and the center superposition checking circle 9；On rudder stock 13 central point messenger wire pendant 15 and the projection line of ground rudder head centrage between deviation be not more than 0.5mm, correct qualified after by rudder stock 13 locking positioning on bracing frame 11；
(4.6) correct qualified after rudder stock 13 spot welding is fixed on rudder blade, welding process is wanted the moment detect the perpendicularity of itself and rudder blade upper sealing plate 5 with levelness and the moment of horizon rule detection rudder stock 13 with square, first slightly weld at face below rudder stock 13, require symmetrical weldering, and want intermittent welding, fully discharge welding stress, in order to avoid persistently welding promotes rudder stock location that deviation occurs, if welding process finds that there is deviation should adjust welding position in time, and checks the strength condition of bracing frame 11；Concrete welding parameter is welding current: 200A～240A, and weldingvoltage: 23V～26V checks the deformation of rudder blade and rudder stock at any time, adjust welding position and welding capacity according to deformation in time in welding process；It is symmetrically welded, it is desirable to every layer of throat depth controls 5～7mm, and the width of per pass welding is not more than 16mm；Welding sequence: butt weld first must be welded before angle welding, and fillet welding in the vertical position was first welded before flat fillet weld.
Based on above technical scheme, optionally, the present embodiment the most also to carry out scarfing cinder to all soldereds after welding, goes to splash, polish smooth, and check the step of weldquality, to ensure soldering reliability and overall appearance.After qualified, rudder blade inside can be carried out being coated with antirust oil antirust.
For high-speed boat, generally arrange on the upper and lower shrouding 5,6 of rudder blade and be respectively arranged with blowoff cock 12, as it is shown in figure 1, in the present embodiment above-mentioned steps (4) is described rudder stock 13 is welded with rudder blade after by blowoff cock 12 also by welding mode be fixed on rudder blade.
Need to check rudder blade principal dimensions after step (3.5), it is ensured that the height of rudder blade and width difference should be not more than ± 0.5mm；The middle section levelness deviation of upper and lower shrouding 5,6 should be not more than ± 1mm, and the levelness deviation of lagging edge tail liner plate 7 should be not more than ± 1mm, carries out firer's correction if overproof.
Compressed air can be used to carry out for rudder blade air seal test in step (5), test pressure select 30-50kPa, depending on concrete rudder blade specification, qualified after on rudder blade inwall fill pitching paint protect.
For the bracing frame 11 for supporting rudder stock 13 described in the present embodiment, its concrete structure includes former and later two identical support seats 11.1 being fixed with one, relative symmetry is arranged, each top supporting seat 11.1 is installed with support ring 11.2, on ring body, hoop is laid and is provided with multiple adjustment jackscrew 11.3, during perpendicularity generation deviation between the levelness and rudder blade upper sealing plate 5 of rudder stock 13, rudder stock 13 can be corrected by adjusting the adjustment jackscrew 11.3 of correct position.The above, be only presently preferred embodiments of the present invention, is not the restriction that the present invention makees other form, and any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as the Equivalent embodiments of equivalent variations.But every without departing from technical solution of the present invention content, any simple modification, equivalent variations and remodeling above example made according to the technical spirit of the present invention, still fall within the protection domain of technical solution of the present invention.
