[0002] Coaming plate bending machine and method [0003]

The present invention relates to a coaming member bending apparatus and method, and more particularly, to a coaming member bending apparatus and method for bending a coaming member before installing the coaming member.

Generally, the coaming member is installed at a predetermined position of the ship so as to surround the specific area of the ship to prevent water or oil left in the area from flowing out to the outside, or to prevent water from flowing into the enclosed area .

The coaming member is welded and bent according to its position.

Korean Patent Laid-Open Publication No. 10-2006-0049929 provides a coaming plate bending jig.

A conventional coaming member bending apparatus includes a hydraulic cylinder device fixed on a sheet; A pad provided at the tip of the rich rod of the hydraulic cylinder apparatus; A cylinder side mold mounted on the pad for applying a force to a coaming plate to be bent; A fixing stopper installed to be spaced apart from the front of the hydraulic cylinder device and supporting the coaming plate to be bent from behind; A bending mold positioned behind the coaming plate bent by the cylinder side mold and formed to be inserted into the fixing stopper to adjust a bending angle of the coaming plate; .

Such a conventional coaming member bending apparatus has a problem that it is difficult to finely adjust the bending angle.

It is an object of the present invention to provide a coaming member bending apparatus and method capable of preventing damage to a coating without using a firearm and fabricating a coaming member in accordance with a desired angle.

The present invention provides a bending apparatus including a workbench for bending a coaming member, the bending apparatus being fixed to the workbench and adjusting a bending angle of the coaming member; A cylinder side mold for bending the coaming member corresponding to the bending mold; And a hydraulic cylinder fixed on the workbench and adapted to apply a force corresponding to the cylinder side mold frame to the bending mold frame.

Preferably, the cylinder side mold frame can be changed according to the bending angle, and the bending mold can be changed according to the bending angle.

Disposing a coaming member between the cylinder side mold and the bending mold; The surface of the comer member is brought into close contact with the cylinder side mold by the hydraulic cylinder; And applying a force to the hydraulic cylinder to bend the coaming member along the cylinder side mold.

The apparatus and method for bending a comer member according to the present invention can prevent a damage of a painting by using a hydraulic cylinder without using a firearm and can manufacture and replace a mold suitable for an angle, Effect.

2 is a cross-sectional view of a bending mold and a cylinder side mold of a coaming member bending apparatus according to an embodiment of the present invention.
FIG. 3 is a process diagram showing a bending process of a coaming member using a coaming member bending method according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view of a coaming member bending apparatus according to an embodiment of the present invention, and FIG. 2 is a sectional view of a bending mold and a cylinder side mold frame of the coaming member bending apparatus according to the embodiment of the present invention. 3 is a process diagram showing a bending process of a coaming member of a coaming member bending method according to an embodiment of the present invention.

Referring first to FIG. 1, a coaming member bending apparatus 100 according to an embodiment of the present invention includes a bending mold 110, a cylinder side mold 120, and a hydraulic cylinder 130.

The bending form 110 is provided on the upper surface of the work table 1 for bending the combing member 2. The bending mold 110 is fixed to the work table 1 and a cylinder side mold 120 to be described later is brought into close contact with the bending mold 110. The bending form 110 may be fixed by welding, but is preferably replaceably coupled to the work table 1 by means of screws.

The cylinder side mold 120 is spaced apart from the bending mold 110 on the upper surface of the work table 1 so as to correspond to the bending mold 110. The cylinder side mold 120 is provided at one end of a hydraulic cylinder 130 to be described later and is moved by the force of a hydraulic cylinder 130 which will be described later. The cylinder side mold 120 may be welded to one end of a hydraulic cylinder 130, which is described later, and is preferably screw-engaged and replaceably engaged.

The hydraulic cylinder 130 is installed on the upper surface of the work table 10 and is provided with the cylinder side mold 120 at one end and forces the cylinder side mold 120 to correspond to the bending mold 110 . When the hydraulic cylinder 130 is loosened, the cylinder side mold 120 is brought into close contact with the surface of the bending mold 110. The cylinder side mold 120 is moved by the force of the hydraulic cylinder 130 so that the coaming member 2 placed between the bending mold 110 and the cylinder side mold 120 is bent.

The hydraulic cylinder 130 may be powered by a hydraulic pump 133 and the hydraulic pump 133 may be installed in the work table 1. [

2 is a cross-sectional view of a bending mold and a cylinder side mold of a coaming member bending apparatus according to an embodiment of the present invention.

Referring to Fig. 2, various embodiments of the bending mold and the cylinder side mold are shown in (a), (b), and (c).

The operator can adjust the bending angle using the bending molds 210, 310, and 410 and the cylinder side molds 220, 320, and 420.

The worker can manufacture and use the bending molds 210, 310 and 410 and the cylinder side molds 220, 320 and 420 according to the angle to be bent and selectively use the bending molds 210, 310 and 410 and the cylinder side molds 220, 320 and 420, And the combing member 2 is bent.

3 is a process diagram showing a bending process of a coaming member of a coaming member bending method according to an embodiment of the present invention.

A method of bending the coming member of the present invention will be described with reference to FIG.

The operator places the coaming member 2 between the bending mold 110 and the cylinder side mold 120.

When the worker operates the hydraulic cylinder 130, the coaming member 2 comes into close contact with the bending mold 110 and the cylinder side mold 120.

When the operator operates the hydraulic cylinder 130, the coaming member 2 is closely contacted with the cylinder side mold 120, and the coaming member 2 is brought into close contact with the bending mold 110 and the cylinder side mold 120, The hydraulic cylinder 130 applies a force so that the piston 2 is bent.

The bending comed member 3 can be obtained by the above method.
