Abstract

The invention discloses a manufacturing method of a buoy and relates to the field of surface vessels. The manufacturing method comprises the steps that three V-shaped openings are cut in a first metal plate longitudinally in a partitioned mode; then a second metal plate is made to be aligned to the first metal plate, a triangular flat plate is pressed and folded longitudinally on the second metal plate along the tip of the V-shaped opening in the middle of the first metal plate, and then two oblique plates are pressed and folded longitudinally on the two side edges of the triangular flat plate along the tips of the other two V-shaped opening correspondingly; the outer side of each oblique plate is pressed and folded vertically upwards, so that a buoy body is formed; the adjacent edges of the V-shaped openings are welded, then the two higher edges are welded in a butt joint mode, a V-shaped head portion is formed, and the initial portion of the buoy body is welded to the buoy head portion; and a stern transom plate is welded to the buoy body, so that a buoy shell is formed, and a sealing panel is welded to the buoy shell. Compared with the prior art, the buoy is provided with the V-shaped head portion, the lifting-resisting function is good, a ship body is made to ascend when a ship accelerates, the speed can be increased rapidly, the number of weld joints is small, the buoy is not prone to deformation, and the cost is low.

Description

The manufacture method of floating drum

Technical field

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

Background technology

The floating drum of existing ship both sides dress, be mostly circular, circular floating drum without hindrance liter effect, 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 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 the first metallic plate is spaced along its length determines three " V " type breach；

B, by longitudinally-aligned with described first metallic plate for second metallic plate wide with described first metallic plate, on the second metallic plate, the tip along " V " the type breach in the middle of the first metallic plate goes out a triangle flat board to the back segment longitudinal direction backfin of the second metallic plate, dual-side at triangle flat board goes out a hang plate along the most advanced and sophisticated backfin the most respectively of two other " V " type breach again, and two hang plates and triangle flat board constitute the base plate of floating drum；The most again by the outside upright upwards backfin of each hang plate, define buoy main body；

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, buoy main body stem compressing for step B is welded with pontoon nose；

D, the 3rd metallic plate is cut into stern transom plate, this stern transom plate is welded on the buoy main body that step B prepares, forms spar hull；

E, on described spar hull weld panel, this spar hull is sealed.

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

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

2, compressing due to V-type head, the most each free entire plate cutting of buoy main body of whole floating drum, as long as by V-type floating drum head doubling welding and welding stern transom plate, buoy main body and panel, 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 the first metallic plate a is spaced along its length determines three " V " type breach 1,2,3；

B, by longitudinally-aligned for the second metallic plate b wide for metallic plate a with first and the first metallic plate a, on the second metallic plate b, the tip along " V " the type breach 2 in the middle of the first metallic plate a goes out a triangle flat board 4 to the back segment longitudinal direction backfin of this metallic plate, dual-side at triangle flat board 4 goes out hang plate 5 and 6 along the most advanced and sophisticated backfin the most respectively of " V " type breach 1 and 3 again, and two hang plates and triangle flat board constitute the base plate of floating drum；The most again by the outside 7 and 8 upwards backfin of hang plate 5 and 6, define buoy main body；

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, buoy main body stem compressing for step B is welded with pontoon nose；

D, the 3rd metallic plate is cut into stern transom plate 9, this stern transom plate is welded on the buoy main body that step B prepares, forms spar hull；

E, on spar hull weld panel 10, this spar hull is sealed.

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

Owing to V-type head, the most each free entire plate cutting of buoy main body of whole floating drum are compressing, as long as by V-type floating drum head doubling welding and welding stern transom plate, buoy main body and panel, 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. the manufacture method of a floating drum, it is characterised in that: comprise the steps:

E, on described spar hull weld panel, this spar hull is sealed.
