Abstract

The invention discloses a manufacturing method of a marine buoy and relates to the filed of shipping. The method comprises the following steps of cutting the front end of a metal plate into three V-shaped openings along the length direction; longitudinally pressing and folding the metal plate into a triangular flat plate from the tip end of the middle V-shaped opening to the rear section of the metal plate, and longitudinally pressing and folding the two sides of the metal plate into sloping plates along the tip ends of the other two V-shaped openings respectively, wherein the two sloping plates and the triangular flat plate form the bottom plate of the buoy; upwards and inwards pressing and folding the outer side of each sloping plate, and welding the two folded sides to form a buoy body; oppositely folding and welding the adjacent sides of the V-shaped openings to form a V-shaped head part, and welding a sealing plate to the head part; welding a stern transom plate to the buoy body to form a buoy shell. Compared with the prior art, the buoy has the advantages that due to the fact that the buoy is provided with the V-shaped head part, the elevation-preventing effect is high, and when a ship is driven and accelerated, a ship body floats, and the speed is quickly increased; due to the fact that the number of welding seams is small, the buoy is not easily deformed, the cost is low, and the strength of the buoy can reach that of a buoy made of glass fiber reinforced plastics.

Description

The manufacture method of floating drum peculiar to vessel

Technical field

The present invention relates to above water craft technical field, the manufacture method of especially a kind of floating drum peculiar to vessel.

Background technology

The floating drum of existing ship both sides dress, be mostly circular, the circular without hindrance liter effect of floating drum, and when foot speed is fast or when accelerating, hull will not float, and resistance will not reduce, ship's speed difficulty promotes, and fast running is difficult.

Furthermore, existing floating drum peculiar to vessel is made with fiberglass mostly, complex manufacturing technology, and cost is high.

Summary of the invention

Problem to be solved by this invention is to provide the manufacture method of a kind of simple in construction, technique floating drum peculiar to vessel simple, with low cost.

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 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 floating drum；Then again by backfin inside on the lateral of each hang plate, two flangings are welded, defines the buoy main body of closed upper part；

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 head, then on " V " type head welded seal plate；

D, another metallic plate is cut into stern transom plate, this stern transom plate is welded on the step B buoy main body tail end prepared, forms the spar hull sealed.

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

1, owing to floating drum has V-type head, its resistance rises effect greatly, when foot is accelerated, makes hull float, and speed-raising is fast.

2, owing to the V-type head of whole floating drum, buoy main body are compressing by entire plate cutting, as long as welding stern transom plate and V-type pontoon nose doubling welding and buoy main body doubling being welded, can be formed, thus the manufacture of floating drum becomes simple easy, weld seam is few, and the amount of labour is few, and floating drum is unlikely to deform, with low cost, and the intensity of the floating drum that fiberglass is made can be reached.

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 a rectangular metallic plate；

B, on this metallic plate, go out a triangle flat board 4 along the tip of middle " V " type breach 2 to the back segment longitudinal direction backfin of this metallic plate, again the dual-side of triangle flat board 4 along " V " type breach 1 and 3 most advanced and sophisticated longitudinally respectively backfin go out hang plate 5 and 6, two hang plates and triangle flat board constitute the base plate of floating drum；Then again by the upwards inwardly backfin of the outside 7 and 8 of hang plate 5 and 6, two flangings are welded, forms the buoy main body of closed upper part；

C, by the doubling welding of adjacent for each " V " type breach limit, then docking welding is continued on the both sides that will exceed, and forms " V " type head, then on " V " type head welded seal plate 10；

D, another metallic plate is cut into stern transom plate 9, this stern transom plate is welded on the step B buoy main body tail end prepared, forms hermetic spar hull.

Length needs according to hull, the length of buoy main body can use how soon metallic plate longitudinal measure lengthens；The program is also in the protection domain of this right.

Owing to the V-type head of whole floating drum, buoy main body are compressing by entire plate cutting, as long as welding stern transom plate and V-type pontoon nose doubling welding and buoy main body doubling being welded, can be formed, thus the manufacture of floating drum becomes simple easy, weld seam is few, and the amount of labour is few, and floating drum is unlikely to deform, with low cost, and the intensity of the floating drum that fiberglass is made can be reached.

Claims (1)
