Abstract

The invention discloses a manufacturing method of a speed boat and relates to the field of surface ships. The manufacturing method comprises the following steps: cutting the front end of a metal plate along a length direction into three V-shaped notches at intervals; longitudinally folding the metal plate from the tip end of the middle V-shaped notch to the rear section of the metal plate to form a triangular flat plate; longitudinally folding two side edges of the triangular flat plate to form an inclined plate separately; vertically folding the outer side of each inclined plate upwards to form a boat body; welding depressed plates on knuckle lines at two sides of the boat body; welding the V-shaped notches to form a V-shaped boat head; pressing another metal plate to form a tail seal, and welding the tail seal with the tail of the boat body. Compared with the prior art, the manufacturing method of the speed boat has the advantages that a boat hull is formed by cutting and pressing whole plates, so that the boat body is simple and easy to manufacture, and the manufactured speed boat is light in weight, sufficient in strength and rigidity, economical and practical; the boat hull is formed by cutting one metal plate, so that welding points are few, the labor amount is small, and the boat body is difficult to deform.

Description

The manufacture method of speedboat

Technical field

The present invention relates to above water craft technical field, the manufacture method of especially a kind of speedboat.

Background technology

Speedboat is a kind of canoe of high-speed motion on the water surface, all has extensive utilization in military, civilian field, and speedboat is made up of parts such as hull, propeller, steering wheel, electromotors.Present speedboat is all pursuing fast, steady, light and rigidity, and ship speed wants fast, and hull have to be light, but hull is light, then poor stability, and the impact being subject to wave when navigation can produce concussion, situation of jolting, it is easy to cause passenger to fall down, the problem such as dizzy ship；And want hull light, and more Os Draconis, rib and Fu Cang can not be increased, lacked these reinforcing sections, the rigidity of whole hull will reduce, thus, four indexs of fast, steady, light and rigidity of speedboat so that small-sized speedboat becomes a paradox；Due to small-sized speedboat easily manufacture, economical and practical, still meet very much needed for masses；Thus, small-sized speedboat has been carried out various transformation by people, as in order to make small-sized speedboat speed fast, carried out strengthening propeller power to it, but so virtually increase production cost.

Furthermore, existing speedboat, its hull is all that the metallic plate with a piece a piece is assorted to be welded, and manufacturing process is complicated, and pad is many, and hull is easily deformed.

Summary of the invention

Problem to be solved by this invention is to provide the manufacture method of the on-deformable speedboat of speedboat that a kind of manufacturing process is simple and creates.

In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:

Comprise the steps:

A, first three " V " type breach are determined at the front end edge length direction interval of a rectangular metallic plate；

B, on described metallic plate, go out a triangle flat board along the tip of middle " V " type breach to the back segment longitudinal direction backfin of this metallic plate, again the dual-side of triangle flat board along two other " V " type breach most advanced and sophisticated longitudinally respectively backfin go out a hang plate, two hang plates and triangle flat board constitute the base plate of hull；Then again by the upwards backfin of the outside upright of each hang plate, kayak body is defined；The both sides chine of described kayak body welds water squeezing plate；

C, by the doubling welding of adjacent for described " V " type breach limit, then docking welding is continued on the both sides that will exceed, and forms " V " type deflection arch；

D, another metallic plate is cut into stern transom plate, this stern transom plate is welded on the step B kayak body afterbody prepared.

Owing to adopting technique scheme, the present invention compared with prior art, has the advantages that

Owing to the V-type deflection arch of whole hull, kayak body are compressing by entire plate cutting, as long as welding stern transom plate and V-type deflection arch doubling being welded, namely may make up ship shell, thus the manufacture of hull becomes simple easy, and produced speedboat is light, there are again sufficient intensity and rigidity, economical and practical；Again owing to ship shell is to be formed by one piece of metallic plate cutting, pad is few, and the amount of labour is few, and hull is unlikely to deform.

Detailed description of the invention

Below in conjunction with attached Example, the invention will be further described:

Embodiment 1:

Embodiment as shown in Figure 1, Figure 2 and Figure 3, its manufacture method comprises the steps:

A, first three " V " type breach 1,2,3 are determined at the front end edge length direction interval of rectangular metallic plate；

B, the on a metal plate tip of edge " V " type breach 2 go out a triangle flat board 4 to the back segment longitudinal direction backfin of this metallic plate, again the dual-side of triangle flat board along two other " V " type breach 1,3 most advanced and sophisticated longitudinally respectively backfin go out hang plate 5,6, two hang plates and triangle flat board constitute the base plate of hull；Then again by outside 7 and 8 backfin straight up of each hang plate, kayak body is defined；The both sides chine of kayak body welds water squeezing plate 9；

C, by the doubling welding of adjacent for " V " type breach 1,2,3 limit, then docking welding is continued on the both sides that will exceed, and forms " V " type deflection arch；

D, another metallic plate is cut into stern transom plate 10, this stern transom plate is welded on the step B kayak body afterbody prepared.

Owing to the V-type deflection arch of whole hull, kayak body are compressing by entire plate cutting, as long as welding stern transom plate and V-type deflection arch doubling being welded, namely may make up ship shell, thus the manufacture of hull becomes simple easy；Again owing to ship shell is to be formed by one piece of metallic plate cutting, pad is few, and the amount of labour is few, and hull is unlikely to deform.

Claims (1)

1. a manufacture method for speedboat, includes hull, it is characterised in that: its manufacturing step is as follows:

A, first three " V " type breach are determined at the front end edge length direction interval of a rectangular metallic plate；

B, on described metallic plate, go out a triangle flat board along the tip of middle " V " type breach to the back segment longitudinal direction backfin of this metallic plate, again the dual-side of triangle flat board along two other " V " type breach most advanced and sophisticated longitudinally respectively backfin go out a hang plate, two hang plates and triangle flat board constitute the base plate of hull；Then again by the upwards backfin of the outside upright of each hang plate, kayak body is defined；The both sides chine of described kayak body welds water squeezing plate；

C, by the doubling welding of adjacent for described " V " type breach limit, then docking welding is continued on the both sides that will exceed, and forms " V " type deflection arch；
