Abstract

The present invention discloses a kind of manufacture method of speedboat, is related to above water craft field, and its manufacture method determines three " V " type breach for the front end of a metallic plate is spaced along its length；Go out a triangle flat board along the back segment longitudinal direction backfin of the tip to the metallic plate of " V " type breach of centre on a metal plate, then backfin goes out a hang plate respectively in two sides of triangle flat board longitudinal direction, then by the upward backfin of the outside upright of each hang plate, form kayak body；Water squeezing plate is welded on the both sides chine of kayak body；" V " type breach is welded, forms " V " type deflection arch；Sealed into tail with another pressing metal plates, welded with the afterbody of hull again；Compared with prior art, due to ship shell cut by entire plate it is compressing, so as to the manufacture of hull become it is simple easily and the speedboat manufactured is light, there is sufficient intensity and rigidity again, it is economical and practical；Again because ship shell is to be cut to form by one piece of metallic plate, pad is few, and the amount of labour is few, and hull is unlikely to deform.

Description

The manufacture method of speedboat

Technical field

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

Background technology

Speedboat is a kind of canoe of the high-speed motion on the water surface, has extensive utilization in military, civilian field, speedboat is by ship The parts such as body, propeller, steering wheel, engine form.Present speedboat is all fast, steady, light and rigid in pursuit, and ship speed is fast, ship Body has to gently, but hull is light, then stability is poor, can be produced concussion, situation of jolting by the impact of wave in navigation, easily Cause passenger to fall down, dizzy ship the problems such as；And want hull light, it must can not increase more keel, rib and floating warehouse, lack this A little reinforcing sections, the rigidity of whole hull will reduce, thus, fast, steady, light and four indexs of rigidity of speedboat so that small-sized fast Ship turns into a paradox；Due to small-sized speedboat easy to manufacture, economical and practical, still meet very much needed for masses；Thus, people Various transformations have been carried out to small-sized speedboat, such as in order to make small-sized speedboat speed fast, increasing propeller power, but such nothing are carried out to it Production cost is increased in shape.

Furthermore existing speedboat, its hull are welded with one piece one piece of metallic plate is assorted, and manufacturing process is multiple Miscellaneous, pad is more, and hull is easily deformed.

The content of the invention

The speedboat that problem to be solved by this invention is to provide a kind of manufacturing process simply and created is on-deformable fast The manufacture method of ship.

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

Comprise the following steps：

A, first the front end of a rectangular metallic plate is spaced along its length and determines three " V " type breach；

B, the sophisticated back segment longitudinal direction backfin to the metallic plate of " V " type breach on the metallic plate along centre goes out one or three Angle flat board, then backfin goes out a hang plate respectively in the tip longitudinal direction of two other " V " type breach of the both sides edge of triangle flat board, two Individual hang plate and a triangle flat board constitute the bottom plate of hull；Then again by the upward backfin of the outside upright of each hang plate, Form kayak body；Water squeezing plate is welded on the both sides chine of the kayak body；

C, the adjacent side doubling welding of " V " type breach by described in, then butt welding is continued on the both sides being higher by, formed " V " Type deflection arch；

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

Due to compared with prior art, being had the advantages that using above-mentioned technical proposal, the present invention：

Due to the V-type deflection arch of whole hull, kayak body cut by entire plate it is compressing, as long as welding stern transom plate and by V-type Deflection arch doubling is welded, you can forms ship shell, so as to which the manufacture of hull becomes simple easy, and the speedboat manufactured is light, has again Sufficient intensity and rigidity, it is economical and practical；Again because ship shell is to be cut to form by one piece of metallic plate, pad is few, and the amount of labour is few, ship Body is unlikely to deform.

Brief description of the drawings

Fig. 1 is the structural representation before the backfin of the present invention.

Fig. 2 is the upward view of the formation speedboat of embodiment 1.

Fig. 3 is Fig. 2 A-A cutaway view Amplified images.

Embodiment

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 comprise the following steps：

A, first the front end of rectangular metallic plate is spaced along its length and determines three " V " type breach 1,2,3；

B, the back segment longitudinal direction backfin on a metal plate along the tip of " V " type breach 2 to the metallic plate goes out a triangle flat board 4, In the tip longitudinal direction of two other " V " type breach 1,3 of the both sides edge of triangle flat board, backfin goes out hang plate 5,6 respectively again, two Hang plate and triangle flat board constitute the bottom plate of hull；Then again by the backfin straight up of outside 7 and 8 of each hang plate, shape Into kayak body；Water squeezing plate 9 is welded on the both sides chine of kayak body；

C, the adjacent side doubling of " V " type breach 1,2,3 is welded, then butt welding is continued on the both sides being higher by, formed " V " Type deflection arch；

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

Due to the V-type deflection arch of whole hull, kayak body cut by entire plate it is compressing, as long as welding stern transom plate and by V-type Deflection arch doubling is welded, you can ship shell is formed, so as to which the manufacture of hull becomes simple easy；Again because ship shell is by one piece of metallic plate Cutting is formed, and pad is few, and the amount of labour is few, and hull is unlikely to deform.

Claims (1)

1. a kind of manufacture method of speedboat, includes hull, it is characterised in that：Its manufacturing step is as follows：

A, first the front end of a rectangular metallic plate is spaced along its length and determines three " V " type breach；

B, go out a triangle along the sophisticated back segment longitudinal direction backfin to the metallic plate of " V " type breach of centre on the metallic plate to put down Plate, then backfin goes out a hang plate respectively in the tip longitudinal direction of two other " V " type breach of the both sides edge of triangle flat board, two are inclined Swash plate and a triangle flat board constitute the bottom plate of hull；Then the upward backfin of the outside upright of each hang plate is formed again Kayak body；Water squeezing plate is welded on the both sides chine of the kayak body；

C, the adjacent side doubling welding of " V " type breach by described in, then butt welding is continued on the both sides being higher by, form " V " type ship Head；

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