The specific embodiment
Below we combine accompanying drawing and concrete embodiment to come the manufacturing approach of interconnection system rudder horn guiding device of the present invention done further in detail to set forth, but can not limit protection scope of the present invention with this.
The design of line style section and the fanning strip suture road of guiding device are provided with:
Say the line style section of design guiding device earlier; Make and be connected between stern zone hull bottom curvature line style and the dripping water type rudder horn; According to arc transition between hull bottom curvature surface and the rudder horn, select suitable circular arc section data point, to guarantee to be connected the correctness of line style.
Above-mentioned guiding device line style section locator value acquiring method is: is the datum mark fan out at rudder horn rudder bearer bow stern two ends with the rudder bearer center line, and branch sections such as equilibrium are asked its locator value, make section and make jointing line simultaneously.The R value of stern end location circular arc section is 150mm; The bow end is 250mm, and with branch circular arcs such as the overlapping equilibrium of circular arc section adjustment S shape offset, offset fills a vacancy; Emit the smooth curve of fairing; The difference that has promptly reduced circular arc housing curvature surface changes, and makes the stress point of each part balanced, has increased housing streamline line style simultaneously again.
In the design phase of guiding device drawing, the circular arc value that at first will make the commentaries on classics circle guiding device shell plates at bow stern two ends is R150mm-250mm, and as benchmark, sets the anchor point of each section of circular arc, on anchor point, obtains each circular arc section.Because it is different with the height and the width value that the hull bottom curve connects to change circle deflector part, other changes the circle section and is irregular ellipse.For this reason, in the setting-out process of sectional line style,, make different curvilinear plane coordinate figures the overlapping circular arc five equilibrium that carries out of all directions section.Refuting with batten on the basis of getting each branch offset, replenishing its damaged some offset based on the actual joint number difference situation of minute circular arc, establishing new line style data point with extending tangent rule, control changes and the progression difference with the curvature of each line segment of adjustment fan out face.Make line style progressively smooth transition to optimal light along point, and set up smoothly that the three-dimensional curved surface changes the circular arc line style, through the reasonability of customized section appearance case Direct Test line style, see Fig. 3 simultaneously.
The line style design that is connected in guiding device and ship stern bottom its objective is and designs the appearance case that cooperates deflector to make, and on the deflector part, ruling foundation is provided.
Design fanning strip suture road; It is that benchmark is located to the both sides fan out with dripping water type rudder horn center of arc's point all that plate suture road is arranged on bow stern two ends; Make deflector part housing longitudinal curvature gesture stress point balanced; Implement fan-shaped location breaking joint line to reduce the vertical and horizontal curvature gesture of deflector, design kind case in order to the check line style according to design result.Because the curvature surface of shipform itself, making changes circular deflector in length and breadth to all having degree of curvature.Be provided with at the plate seam for this reason and must consider actual degree of curvature factor.According to experience of practical, it is the effective method that reduce to change round sheet material degree of curvature that fan out intercepting section is provided with jointing line.We are producing the design phase for this reason, on the basis of guiding device completion line style design, have taked the fan-shaped method that jointing line is set at bow stern end, see Fig. 2.
The actual production construction stage of rudder horn guiding device:
At first, from the loading and unloading of monoblock steel plate, the size of institute's blanking plate is two adjacent deflector part dimensions, and on this flitch, reserves panel shrinkage and allowance.In the workshop, utilize lathe to roll out the unidirectional circular arc in cross section of deflector part then, the making of multidirectional curvature gesture then need be transported to the hot work place and process.
Secondly, after the deflector part is transported to the hot work place, earlier by the flame forming plate workmen fiery processing line of on flitch, striking; Again above-mentioned flitch utilization " being ridden sign indicating number " is fixed on the processing platform; And on flitch, utilize oil pump to apply downward pressure, and implement thermal-flame and water-cooling method simultaneously flitch is dried by the fire the burning roof pressure, hocket; Make and the horizontal slowly distortion of flitch meet a kind case size until the horizontal circular arc of flitch and vertical curvature through multi-pass operation.Above-mentioned " riding sign indicating number " be a rod iron or steel pipe bending is certain angle from the middle part, the size of bending angle is carried out as required, needs " riding sign indicating number " of subsequent use different bendings during construction.On processing platform, then be provided with a plurality of circular holes, this circular hole is that the end for " ride sign indicating number " inserts and designs.Can successfully the deflector part of difformity and bending degree be fixed by " riding sign indicating number " and processing platform.
Once more; The appearance case that to make the design phase is placed into through in the flitch after the extreme misery processing; Check whether the amplitude circular arc line that needs vertically with transverse curvature meet the actual center of arc of line style, and whether the edge of inspection flitch is docile with the appearance case, then do not repeat the constructing operation that above-mentioned thermal-flame and water-cooled are but dried by the fire the burning roof pressure as if meeting with the appearance case; Fit tightly until flitch and appearance case, the flexibility of surperficial flitch and curvature gesture meet the requirements;
At last, with allowance under cutting out on the flitch of making regulation flexibility and curvature gesture, and it is for use separately to obtain two adjacent deflector parts.
In the flame forming plate process, to the material thickness of steel, temperature control, the time of the intensity of a fire and the control of distance, water spray control all has strict requirement.With the thick deflector of certain type ship 12mm is example, because its thickness of slab is thinner, according to shipbuilding material characteristic; We innovate on technology, require to accomplish low temperature, low coverage, fast, closely follow, taked following steps; For reducing temperature; Comb hair distance is controlled between the 40-50mm (conventional be 100mm) intensity of a fire time of staying and is controlled at 2-3 minute (conventional be 6-8 minute, the water spray comb hair is immediately following the intensity of a fire) and has reduced the distortion of material wave inception, has guaranteed the fineness of material.
The processing method that the present invention adopted can substitute the conventional molds processing method, can guarantee the correctness of guiding device sectional line style, reduces the degree of curvature in length and breadth of deflector, makes the diversion shell stress point that is connected with boat bottom balanced, strengthens casing rigidity.Flame forming plate " is ridden sign indicating number ", and the oil pump roof pressure organically combines, and relies on " riding sign indicating number " to dry by the fire the flame forming plate processing technology of burning, and can solve the curvature gesture of part deflector, and the oil pump roof pressure has strengthened the crooked dynamics of its key position, makes deflector to process gradually and puts in place.Because the deflector after the machine-shaping is still keeping firer's allowance for shrinkage; Each part keeps vertically front and back 600mm of wide 250mm-, according to an appearance case, can guarantee the appearance and size of deflector part; Cutting accuracy makes and launches part line style radian and actual appearance case coupling.
