Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machining unit for a bow bottom plate of a ship and a method for machining a bow plate using the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machining unit for machining a plate to be installed in a lower portion of a bow of a ship formed in a streamline shape using an aluminum plate, and more particularly to a machining unit for a bow plate of a ship and a method of machining a bow plate.

In general, plate materials used for manufacturing small ships require plate materials having various materials and shapes. For example, when a ship is manufactured using aluminum material, it is advantageous in terms of weight reduction. Due to the nature of metal, Strength and durability.

The problem to be solved when manufacturing a small-sized ship using aluminum material is molding for a lower portion of a streamlined boat. It is difficult to form a small-sized aluminum boat or a yacht for a player's lower portion. The bottom of the bow is processed by using a rounded convex shape.

For example, a boat or a yacht does not place much importance on the pitching of the hull due to the speed, so it is insensitive to the shape of the bow. However, in the case of a small ship as shown in Fig. 1, Reduction is a very important issue, and agility is directly related to the amount of work or catch. Therefore, the shape of the bottom of the bow, which is regarded as a sensitive part, was controversial in the production of small fishing boats.

In order to prevent such a problem, the aluminum plate used for the ship was used to perform machining through the press equipment for machining of the bow bottom formed in a streamline shape, but the cost for constructing the press equipment relatively increased .

In addition, due to the characteristics of the aluminum plate, after the pressing is difficult, the springback phenomenon, which is a restoring force to return to the original shape, is caused, so that the forming of the lower portion of the player, which is to be made streamlined, has been relatively difficult. Most of the cases were abandoned.

2 to 3, a machining unit 1 for a bow bottom plate of a ship according to an embodiment of the present invention includes a streamlined plate material (not shown) installed on the left and right sides of a bow of a ship using an aluminum plate, Plate type vertical plate unit in which a plurality of plates are arranged in the width direction along the longitudinal direction of the base plate 100 and a curved portion 210 is formed on the upper surface of the base plate 100 in order to process the flat plate type aluminum plate into a streamlined plate material, A hinge unit 300 provided adjacent to the lower end of the curved part 210 and a rotary plate unit 400 connected to the hinge unit 300 and rotated toward the vertical plate unit 200, And the rotary plate unit 400 and the vertical plate unit 200 are fixed to each other with the plate material 2 positioned between the vertical plate unit 200 and the rotary plate unit 400 To include a fixed unit 500.

The machining unit 1 for the player lower plate member is constituted by a machining unit for machining the left side of the lower portion of the bow and a machining unit for machining the right side of the lower portion of the bow. In this embodiment, However, since the configuration for machining the right side of the lower portion of the bow is also configured to correspond to the machining unit 1 for processing the left side, detailed description will be omitted. For reference, the plate material described in the present invention is limited to the use of an aluminum plate having a thickness of about N mm. The N mm is limited to a thickness of 10 mm or less, preferably 5 mm.

The base plate 100 is a kind of support plate for installing the vertical plate unit 200, and will be described in detail after the vertical plate unit 200 is described.

The vertical plate unit 200 is a plate made of steel and arranged vertically in the width direction along the longitudinal direction of the base plate 100 and having a curved portion 210 whose upper surface is inclined from one side to the other side, A plurality of the first to n-th vertical plates 200a to 200n are spaced apart from each other by a predetermined distance in the longitudinal direction of the base plate 100, It is not limited to the number shown in the drawings.

For example, the first vertical plate unit 200 has a predetermined horizontal width and extends from the lower right end toward the upper side in the first vertical length L1 and extends from the lower left end toward the upper side in the second vertical length L2 , And the first longitudinal length (L1) is elongated relative to the second longitudinal length (L2). In addition, the first vertical plate unit 200 has a curved portion 210 which is inclined in one direction from the upper right side to the lower left side, and the curved portion 210 is formed when the plate material provided at the lower portion of the bow of the ship is viewed from the outside And corresponds to a round curvature of an outer circumferential surface corresponding to each divided position when a plurality of circumferentially formed outer circumferential surfaces are divided by a predetermined length.

In particular, when the lower portion of the ship is viewed from above, the horizontal width of the ship is relatively reduced as it goes from the upper portion to the front portion, so that the width of the curved portion 210 also decreases from the first unit vertical plate 200a to the nth unit vertical plate 200n .

In the case of an aluminum plate corresponding to one of the left and right sides of the lower portion of the bow, the vertical plate unit 200 for stably processing the lower portion of the streamlined bow is manufactured, It is possible to reduce the work cost and improve the work efficiency of the operator.

The nth vertical plate unit 200n corresponds to the tip of the lower portion of the bow and has a first longitudinal length L1 and a second longitudinal length L2 relatively longer than the first vertical plate unit 200a described above And the width of the curved portion 210 is also relatively reduced, so that the plate material can be easily processed in such a manner that the cross-sectional area decreases toward the tip portion of the lower portion of the bow. Therefore, the worker can conveniently perform the processing of the plate material 2 in a streamlined shape corresponding to the lower portion of the bow of a small ship without processing the plate material by the press method, which is an expensive operation method.

The curvature of the curved portion 210 may vary according to the shape of the bow of the ship to be manufactured. In this case, the first to n-th unit vertical plates 200a to 200n may be manufactured in accordance with the changed curvature, The operator can cope with the curvature more easily and quickly.

The vertical plate unit 200 extends outward from the uppermost end of the curved portion 210 facing the hinge portion 300 so that the first to nth unit fixing portions 500a to 500n are mounted, And a first engaging portion 220 having a first insertion groove 222 into which the first and second engaging portions 500a to 500n are partially inserted.

The first latching unit 220 may be modified into various forms in which the first to n-th unit fixing units 500a to 500n to be described later can be mounted, and is not particularly limited to the shapes shown in the drawings.

The first insertion groove 222 provides a space through which the lower inner side of the first to nth unit fixing portions 500a to 500n to be described later can be partially inserted to facilitate easy mounting. But may be variously modified without limitation.

The rotation plate unit 400 includes a first insertion slot 412 formed at the tip of the first through n th unit rotation plates 400a through 400n so that the first through n th unit fixing portions 500a through 500n are partially inserted The second insertion groove 412 is open toward the upper side unlike the first insertion groove 222 described above, and the first to n-th unit fixing parts 500a to 500n The first to n-th unit fixing parts 500a to 500n can be conveniently mounted by the operator because the upper inner side can be partially inserted.

For example, in order to mount the first unit fixing portion 500a, the upper inner side of the first unit fixing portion 500a is partially inserted into the second insertion groove 412, The insertion is completed easily. For reference, it is also possible to insert the first unit fixing portion 500a into the second insertion groove 412 after inserting the first unit fixing groove 222 first.

The first and second locking portions 220 and 410 are formed at relatively high positions from the first unit vertical plate 200a to the n-th unit vertical plate 200n, State can be maintained.

The hinge unit 300 is installed separately from the first to n-th unit vertical plates 200a to 200n adjacent to the inclined lower end of the curved part 210. The hinge unit 300 provided in the present embodiment has an L- One end of which is fixed to the first unit vertical plate 200a and the other end of which is fixed to the first unit rotary plate 400a so that the first unit rotary plate 400a is easily rotated toward the first unit vertical plate 200a .

The hinge unit 300 is rotatable about the first unit rotary plate 400a so that the first unit rotary plate 400a can be rotated toward the first unit vertical plate 200a, The unit vertical plate 200a is disposed at a relatively high position from the first unit vertical plate 200a to the n-th unit vertical plate 200n. Therefore, the first through n-th unit vertical plates 200a, With a relative height difference.

The rotary plate unit 400 is rotatably connected to the vertical plate unit 200 via the hinge 300 in a state facing the vertical plate unit 200, When the n-th unit vertical plates 200a to 200n are rotated toward the first to nth unit rotary plates 400a to 400n, the inner circumferential surfaces of the first to nth unit rotary plates 400a to 400n are curved portions 210 Is kept in a close contact state.

When the plate member 2 is positioned between the vertical plate unit 200 and the rotary plate unit 400 in this state, the lower surface of the plate member 2 is curved in the curved portion of the first internal unit n-unit vertical plates 200a to 200n And the upper surface thereof is held in close contact with the inner circumferential surfaces of the first to nth unit rotary plates 400a to 400n so that the stationary state of the plate member 2 is maintained.

Therefore, even if the fixed state is stably maintained regardless of the weight of the plate material 2 and the heat treatment for maintaining the shape of the streamline is performed, the shape corresponding to the lower portion of the bow of the ship is not produced .

The rotary plate unit 400 is rotatably connected to the hinge 300 in a state of facing the curved portion 210 of the first to nth unit vertical plates 200a to 200n, 1 to n th unit rotating plates 400a to 400n. For example, since the first unit rotary plate 400a has a curvature similar to that of the curved portion 210, the first unit vertical plate 200a has a mating surface facing the first unit vertical plate 200a, N unit vertical plates 200a to 200n and the first to n th unit rotating plates 400a to 400n are arranged in a stable state when they are disposed between the first to n-th unit rotating plates 400 and 200 and the rotating plate unit 400, ≪ / RTI >

Therefore, it is possible to easily perform machining in the form of a streamlined shape of the lower portion of the bow when the streamlined state is observed after the plate material 2 is processed. Also, when the outer peripheral face of the plate material 2 is processed into a streamline shape, And the quality of the finished product can be improved.

Since the first to nth unit rotating plates 400a to 400n correspond to the width and the thickness of the curved portion 210, when rotated toward the first to nth unit vertical plates 200a to 200n, And is stably fixed by the fixed unit 500 to be described later in a viewing state.

When the first to n-th unit rotating plates 400a to 400n are rotated toward the first to n-th unit vertical plates 200a to 200n, the first to nth unit rotating plates 400a to 400n, The rotation plate unit 400 is rotated toward the vertical plate unit 200 so that the interval between the n-th unit vertical vertical plates 200a to 200n is shorter than the thickness of the plate material 2, Thereafter, the fixed state through the fixed unit 500 is stably maintained. Further, the upper surface or the lower surface of the plate 2 is not damaged or deformed and can be easily processed in a streamlined manner.

Since the rotary plate unit 400 is reduced in width from the first unit rotary plate 400a to the n th unit rotary plate 400n in a form corresponding to the horizontal width of the curved portion 210, The sheet material can be processed in a streamlined form.

Referring to FIG. 4, the base plate 100 corresponds to a bottom plate on which the above-described vertical plate unit 200 is installed. When viewed from above, the first unit vertical plate 200a is provided with a hinge 300 N unit vertical plate 200n at a position where the first unit fixing portion 500a of the first unit vertical plate 200a is disposed, And the horizontal width decreases toward the n-th unit fixing portion 500n of the n-th unit fixing portion 200n. The shape corresponds to the left side of the plate provided at the lower part of the bow, and the opposite shape to the right side, and a description thereof will be omitted.

The base plate 100 includes a fitting plate 110 disposed on the upper surface in a state of being opposed to each other in the longitudinal direction and having a groove portion 112 into which the lower ends of the first to nth unit vertical plates 200a to 200n are inserted, do. The fitting plate 110 is fixed in various ways so as to be stably fixed on the upper surface of the base plate 100 even when a plurality of the first to nth unit vertical plates 200a to 200n are mounted, .

The first through n-th unit vertical plates 200a through 200n are held in a fixed state after they are inserted into the groove 112 and are vertically inserted using a welding method or another fixing member (not shown) maintain.

2 or 5, the fixed unit 500 is installed between the vertical plate unit 200 and the rotary plate unit 400 in a state where the plate members 2 to be installed on both sides of the bow of the ship are positioned The first to nth unit fixing plates 500a to 400n for holding the first to nth unit rotating plates 400a to 400n, which are rotated toward the first to nth unit vertical plates 200a to 200n, To 500n).

In this embodiment, the first unit fixing part 500a includes a body part (not shown) inserted into the first and second locking parts 220 and 410, 402). The first unit vertical plate 200a and the first unit rotary plate 400a are relatively moved toward the second insertion groove 412 from the upper portion of the body 402 to fix the first unit vertical plate 200a and the first unit rotary plate 400a in a fixed state Bolts < / RTI >

The body portion 402 is inserted into the first and second locking portions 220 and 410 which are held in a rectangular shape having an open center and the fixing bolt 404 is relatively moved toward the second insertion groove 412 The first unit vertical plate 200a can be maintained in a state where the first unit rotary plate 400a is fixed to the first unit vertical plate 200a.

The fixing bolt 404 is threaded along the outer longitudinal direction and a tubular relative rotating member is inserted into the body portion 402 into which the fixing bolt 404 is inserted so that the fixing bolt 404 and the fixing bolt 404 are relatively rotated. Or a thread is formed along the inner longitudinal direction of the body portion 402 and the fixing bolt 404 is screwed and moved toward the second insertion groove 412. [ Further, the present invention is not limited to the above-described configuration.

However, since there are a plurality of the first to n-th unit fixing parts 500a to 500n, the bolt method is used for facilitating installation and disassembly for more efficient work by the operator.

The plate processing unit 1 according to the present embodiment includes first to n-th unit vertical plates 200a to 200n disposed along the base plate 100, The unit vertical plates 200a to 200n include a spacing holder 10 which is fitted to the sides of the unit vertical plates 200a to 200n. The spacing holder 10 includes a plurality of first to n-th unit vertical plates 200a to 200n, The unit vertical plates 200a to 200n may be spaced apart from each other by a predetermined distance.

A method of working a bow bottom plate according to an embodiment of the present invention will be described with reference to the drawings.

3 or 7, in order to process the bottom plate material of the bow, a plate material is arranged between the vertical plate unit and the rotation plate unit to process the plate material to be installed on either the left or right side of the bow of the ship (S200) of fixing the plate material through the fixing unit after rotating the rotating plate unit toward the vertical plate unit (S200), performing a heat treatment in a state where the plate material is fixed in a streamlined manner (S300 (S400) a step of installing a reinforcing material on the upper surface of the plate material so that the shear-deformed plate material is not restored to the pre-heat treatment state after the heat treatment is completed (S400); And releasing the fixed state of the fixed unit and withdrawing the sheet material (S500).

The plate material 2 installed at the lower part of the bow of the ship is first cut in a shape corresponding to the position of either the left or right side of the lower part of the bow to form a streamlined shape using the above- ), And rotates the first to n th unit rotating plates 400a to 400n about the hinge 300 in the direction of the arrow.

The first to n-th unit rotary plates 400a (400a, 400b) rotated in a state in which the previously cut plate member 2 is positioned on the upper surface of the curved portion 210 of the first to nth unit vertical plates 200a to 200n To 400n are rotated toward the first to nth unit vertical plates 200a to 200n and the plate material 2 is transferred to the outer side of the processing unit 1 by using the first to nth unit fixing parts 500a to 500n (S200).

For example, when the operator rotates the fixing bolt 404 while inserting the first and second engaging portions 220 and 410 into the body 402 formed in the first unit fixing portion 500a, The fixing bolt 404 is relatively moved toward the locking part 410 to stably maintain the first unit rotary plate 400a in close contact with the first unit vertical plate 200a. In this way, fixing to the plate member 2 is completed when the mounting of the remaining n unit fixing portions is completed.

In this case, the plate member 2 is subjected to the heat treatment in the state where all the first to nth unit fixing parts 500a to 500n are installed (S300). In the case of the heat treatment, a specific temperature is maintained at the upper part of the plate member 2 The plate material 2 is heated until the entire upper surface of the plate material 2 reaches the target temperature by using the heat treatment unit at S310 and maintained for t seconds after the plate material 2 reaches the target temperature, (S320)

For example, the heat treatment for the plate material 2 is carried out by heating to 60 ° C. and then for 15 seconds to heat-treat the plate material made of aluminum plate so as to maintain a streamlined shape, thereby restoring the aluminum plate having a relatively elastic restoring force to a circular shape .

The temperature change during the heat treatment of the plate material 2 can accurately confirm the temperature change state on the outside of the processing unit 1 through the temperature measuring device (not shown).

The heat treatment method may be a heat treatment method or other methods through the heat treatment unit described above, and may be variously modified without particular limitation.

Referring to FIG. 6 or FIG. 8, the heat-treated plate material 2 is formed in a streamlined shape, but it can be restored to a flat plate shape over time due to the characteristics of the aluminum plate. N th unit rotation plates 400a to 400n) are not rotated around the hinge unit 300 so that the first to n-th unit rotation plates 400a to 400n are not rotated around the hinge unit 300, Is welded to the upper surface of the plate material (2) closely contacted with the rotary plates (400a to 400n).

The stiffener 20 has a width corresponding to the width of the first through n-th unit rotating plates, a height of which is relatively short, and has a curvature corresponding to the curvature of the top surface of the plate 2 It is possible to prevent the phenomenon due to the restoring force when the plate member 2 is provided at the lower portion of the actual ship and to improve the supporting force with respect to the plate member 2.

After the fixation to the stiffener is completed, the first to n-th unit rotating plates and the first to n-th unit vertical plates are fixed, It is sufficient to draw out the sheet material processed in a streamlined manner.
