Description

Processing equipment used to manufacture anti-skid decks of HDPE ships}

The present invention relates to processing equipment used in a method for manufacturing a deck of a high-density polyethylene ship, and more particularly, to manufacture a ship made of high-density polyethylene by cutting a high-density polyethylene panel, and after constructing the ship, equipment equipped with a heating wire It relates to processing equipment used in the manufacture of anti-slip decks of high-density polyethylene ships, which can prevent the processed parts from being cut and discarded by performing anti-slip processing using a high-density polyethylene and can quickly perform the construction process.

In general, ships are manufactured with FRP (Fiber-Reinforce Plastic), which has the advantage of low manufacturing cost, but is vulnerable to external shocks and absorbs moisture, so the overall load capacity is reduced, resulting in ship operation stability. There was a problem that it could deteriorate.

In order to overcome this, there are cases in which ships are manufactured through aluminum. Compared to ships made of FRP materials, they are stronger against external shocks and are environmentally friendly. , Compared to ships made of FRP materials, the manufacturing cost is high, and recycling after scrapping is an advantage, but the eco-friendly advantage of recycling scrapped ships adds to the cost of recycling scrapped ships, and there is a problem that recycling is burdensome. could

In addition, since panels of the corresponding material are prepared in the process of manufacturing ships, and the ships are manufactured after processing the panels, the non-corresponding parts of the processed panels are discarded, so additional time and cost are consumed in the processing process. However, there could be a problem that the cost of processing the processed panel could be relatively burdensome compared to the cost of processing the unprocessed panel.

Therefore, in order to solve this problem, various methods are being devised to solve the problems occurring in the processing process while solving the problems of ships made of FRP and aluminum, and means to solve them are needed.

Hereinafter, a preferred embodiment of the present invention in which the object of the present invention can be realized in detail will be described with reference to the accompanying drawings.

In describing the present embodiment, the same name and the same reference numeral are used for the same configuration, and additional description thereof will be omitted.

First, the overall flow of the manufacturing method according to an embodiment of the present invention can be described through FIGS. 1 and 2.

Specifically, Figure 1 is a view for explaining the overall process of a high-density polyethylene ship deck manufacturing method and processing equipment used therein according to an embodiment of the present invention, Figure 2 is a high-density polyethylene according to an embodiment of the present invention It is a diagram shown to explain the manufacturing method of the deck of a polyethylene ship and the processing steps of the processing equipment used therein.

First, as shown in FIG. 1, the manufacturing method according to an embodiment of the present invention includes a preparation step (S10) of preparing a panel (P) to manufacture a high-density polyethylene ship (B), through the preparation step (S10). A cutting step (S20) of cutting the panel (P) to a size corresponding to the deck of the ship (B) using the provided panel (P), and the panel (P) cut through the cutting step (S20). The assembly step (S30) of manufacturing the ship (B) using a ) and sliding on the panel (P) assembled through the assembly step (S30) to prevent slipping while moving the deck of the ship (B) It may include a processing step (S40) of performing an anti-processing.

To explain this in detail for each step, the preparation step (S10) is a step of preparing a material for manufacturing the ship (B), and since the ship (B) is manufactured using high-density polyethylene, the above composed of high-density polyethylene It may refer to a step of providing the panel P.

Here, the use of high-density polyethylene in the manufacture of the ship (B) is to solve the problem of stiffness and moisture absorption of the existing FRP material and the cost and cost of aluminum, and high-density polyethylene is more rigid than FRP and does not absorb moisture. Since the material is hard, the problem of the FRP material can be effectively solved, and since it is hard without absorbing moisture, the loading problem can be effectively solved, and at the same time, since the material is relatively cheaper than the cost of aluminum, the ship made of aluminum ( There may be an advantage that the problem of B) can also be solved together.

Therefore, the ship (B) manufactured by the manufacturing method according to an embodiment of the present invention may configure the deck of the ship (B) using the panel (P) made of high-density polyethylene in the preparation step (S10). The ship (B) composed of such high-density polyethylene may mainly mean a small size, but it may be obvious that it may be included in some configurations in manufacturing a large ship (B) as needed.

In addition, since the panel (P) made of high-density polyethylene is not coated with high-density polyethylene, the overall property of high-density polyethylene, for example, is relatively buoyant, so it effectively secures buoyancy and secures stability. It may also have the advantage of being able to use various properties such as.

On the other hand, when the panel (P) made of high-density polyethylene is provided through the preparation step (S10), in manufacturing the ship (B), cutting according to the part composed of the panel (P) made of high-density polyethylene The cutting step (S20) can be performed, and in the cutting step (S20), only the process of cutting the panel (P) made of high-density polyethylene according to the ship (B) is performed without performing a separate processing process. can do.

In addition, after the panel (P) made of high-density polyethylene is cut to correspond to the ship (B) through the cutting step (S20), the assembly step (S30) for manufacturing the ship (B) is performed. In addition, the process of assembling the panel P performed in the cutting step (S20) according to the design drawing can be performed.

Here, since high-density polyethylene is relatively easily deformed by heat, in the process of combining the panels (P) cut through the cutting step (S20), a separate member may be used to connect them to each other, but the characteristics of high-density polyethylene are utilized. In combining with each other, a method of combining by applying heat can also be used.

If this process is performed, the process of utilizing a separate member is omitted, but it is not necessary to have a separate member, so it is more effective than FRP and aluminum, which were conventionally used to manufacture the ship (B), in terms of cost reduction and time reduction. can be

However, if it is determined that the stability of the vessel (B) made of high-density polyethylene is insufficient, another method capable of improving the stability of the vessel (B) while reinforcing the rigidity inside the vessel (B) made of high-density polyethylene It can be constructed by attaching parts of the material, which has the disadvantage of increasing the weight of the ship (B), but since it effectively improves the stability of the ship (B), the ship (B) with higher stability can be provided There may be advantages to being there.

On the other hand, if the preparation step (S10), the cutting step (S20), and the assembling step (S30) are performed, the prototype of the ship (B) can be completed, and when the prototype of the ship (B) is completed, the processing Step S40 may be performed after the prototype of the ship B is completed.

Here, the processing step (S40) has been exemplified above as representatively performing anti-slip processing, but for trimming the shape of the outer surface of the ship (B) or reducing the resistance for the ship (B) to move forward in the sea It may be an obvious fact that linear processing, shape processing, and the like may be included.

At this time, since the processing step (S40) proceeds after the assembling step (S30) is performed, the panel (P) is provided to manufacture the ship (B) in the conventional technique, and the panel (P) There may be a difference from the process of preferentially performing the processing step (S40) and cutting the panel (P) processed in the processing step (S40).

In general, first processing the panel P as in the prior art may reduce a separate processing process after the assembling step (S30), but processing the panel (P) in the processing step (S40). Of one part, the part that does not correspond to the shape of the ship (B) must be cut, and the part that does not correspond to the ship (B) must be processed at a separate cost while cutting, and the processed panel (P) is processed There may be a disadvantage that the processing cost is relatively high compared to the panel (P) that has not been recycled.

However, since the manufacturing method according to an embodiment of the present invention performs the processing step (S40) after the assembly step (S30) of manufacturing the ship (B), as mentioned above, it is cut and the ship (B) The cost of processing the part that does not correspond to is relatively reduced, and since processing is not performed, there may be an advantage that it is suitable for recycling without processing.

In this way, the processing step (S40) can have an overall high effect if it is performed after the assembly step (S30), and in the manufacturing method according to an embodiment of the present invention, the processing step (S40) is shown in FIG. It may include a process as shown.

Specifically, as shown in FIG. 2, the processing step (S40) is a processing area (S1) for performing anti-slip processing on the deck of the ship (B) manufactured through the assembly step (S30) and anti-slip processing. Includes a division process (S42) of dividing non-processing areas (S2) and (S1) that are not performed, and a heat treatment process (S44) of performing anti-slip processing using processing equipment heated by a hot wire in the processing area (S1). can do.

Here, dividing the processing area (S1) and the non-processing area (S2) (S1) through the division process (S42) is that there is a part that is difficult for passengers to access according to the shape of the ship (B), and the structure Since there may be an inaccessible space due to this, it may be to perform the processing step (S40) more effectively by reducing unnecessary processes by dividing these areas from each other and performing anti-slip processing.

That is, the processing area S1 may refer to a space that is easily accessible to the occupants and requires anti-slip processing, and the non-processing areas S2 and S1 are difficult to access by the occupants as described above. Or, it can mean a space that is inaccessible due to structures.

In this way, if the processing area (S1) and the non-processing area (S2) (S1) are divided through the division process (S42), it will be described in more detail through drawings to be described later, but using the processing equipment The anti-skid process (S44) may be performed on the processing area (S1), and due to the nature of high-density polyethylene, the anti-slip process may be more easily performed by utilizing the high-temperature processing equipment.

However, as described above, since there may be a problem in that stability may be deteriorated in the manufacture of a large ship (B) due to the nature of high-density polyethylene, only the deck of the ship (B) is constructed using the panel (P). A method may be used, which may be variously changed according to the design drawing as described above in the manufacturing step.

That is, when the size of the ship (B) is too large to be made of high-density polyethylene, the panel (P) made of high-density polyethylene can be used only on the deck of the ship (B), and the high-density polyethylene panel (P) can be used on the deck of the ship (B). An attaching process (S46) of attaching the panel P made of polyethylene may be performed.

More briefly, when the vessel (B) is manufactured using the panel (P) made of high-density polyethylene, only the classification process (S42) and the heat treatment process (S44) may be performed, and the vessel ( B) When the panel (P) made of high-density polyethylene is to be used only on the deck of the ship (B) due to a problem of large size or stability, the attaching process (S46) of attaching the panel (P) made of high-density polyethylene And, as described above, after performing the division process (S42), the heat treatment process (S44) can be performed.

Based on the foregoing, reference may be made to FIGS. 3 to 6 to describe the manufacturing process of the present invention with reference to the drawings.

Specifically, FIG. 3 is a view illustrating a method for manufacturing a deck of a high-density polyethylene ship according to an embodiment of the present invention and a preparation step and a cutting step of processing equipment used therein, and FIG. 4 is an embodiment of the present invention. Figure 5 is a drawing for explaining a method for manufacturing a deck of a high-density polyethylene ship and an assembly step of processing equipment used therein according to the present invention, and FIG. Figure 6 is a view for explaining a method for manufacturing a deck of a high-density polyethylene ship according to an embodiment of the present invention and a heat treatment process for processing equipment used therein.

First, as shown in FIG. 3, the preparation step (S10) of preparing the panel (P) made of high-density polyethylene may be performed, and the panel (P) made of high-density polyethylene prepared through the preparation step (S10) According to the design drawing of the ship (B) to be manufactured, the cutting process of cutting into a form corresponding to the ship (B) can be performed.

This may take the form of the ship (B) as shown in FIG. 4, which is only a simple illustration for understanding, and it is obvious that it can take the basic form of the ship (B), so the ship (B) The description of the shape of is omitted.

Here, as shown in FIG. 4, the assembly step (S30) of assembling the ship (B) can be performed, and the ship (B) can utilize the panel (P) made of high-density polyethylene as a whole, It is also possible to increase stability by providing a separate member on the inner side, and if necessary, it may be used only in part according to the design drawing.

In this way, after the preparation step (S10), the cutting step (S20), and the assembling step (S30) are performed, the processing step (S40) can be performed, and as shown in FIG. 5, the heat treatment process ( In order to perform S44), the division process (S42) of dividing the processing area (S1) and the non-processing area (S2) (S1) may be preceded.

Here, the processing area (S1) and the non-processing area (S2) (S1), which are divided through the classification process (S42), can be classified according to whether anti-slip processing is required as described above, but in general, anti-slip While machining is performed, only a relatively low level of machining may be performed in the non-processing areas (S2) (S1) compared to the processing area (S1), and the non-processing areas (S2) (S1) must be non-slip processing. It may not mean that this area is not performed.

As described above, when the processing area (S1) and the non-processing area (S2) (S1) are divided through the division process (S42), the heat treatment process (S44) may be performed, and the heat treatment process According to (S44), anti-slip processing of a predetermined pattern is performed in the processing area (S1), and another pattern or anti-slip processing distinguished from the processing area (S1) is performed in the non-processing area (S2) (S1). This may not be done.

In this way, in the heat treatment process (S44), the processing equipment can be used to perform the anti-slip processing on the processing area (S1), and the processing equipment can be described in more detail with reference to FIGS. 7 and 8.

Specifically, FIG. 7 is a view for explaining the overall configuration of a method for manufacturing a deck of a high-density polyethylene ship according to an embodiment of the present invention and processing equipment used therein, and FIG. 8 is a view according to an embodiment of the present invention. It is a diagram shown to explain a method of manufacturing a deck of a high-density polyethylene ship and an example of utilization of processing equipment used therein.

First, as shown in FIG. 7, the processing equipment according to an embodiment of the present invention includes a mold unit 100 having a predetermined pattern for anti-slip processing on the deck of the ship (B), and the mold unit 100 ) provided on the inside of the mold unit 100 to provide a temperature equal to or higher than the melting point of high-density polyethylene, and a handle unit 300 extending upward from the mold unit 100 to form a handle can include

Here, the mold unit 100 may be provided in a form surrounding the heating wire unit 200, an inner side may be disposed to face the heating wire unit 200, and an outer side of the mold unit 100 may be arranged to face the heating wire unit 200. A set pattern may be formed.

Meanwhile, the heating wire unit 200 may be located inside the mold unit 100, as shown in FIG. 8, and is provided inside the mold unit 100 to generate heat by receiving a separate power supply. may be placed.

In addition, the handle unit 300 may be provided to extend upward from both ends of the mold unit 100, and a part thereof may be tilted so that the mold unit 100 may be tilted at a predetermined angle.

The reason why the handle unit 300 is tilted at a predetermined angle in this way may be to ensure that there is no space in which the mold unit 100 cannot move due to the angle. In order to be tilted at a predetermined angle in this way, the handle unit 300 While extending from both ends of the mold unit 100, bent upward, and bent toward the center in the longitudinal direction of the mold unit 100, in a state in which the handle units 300 extending from both ends are merged into one path If it is formed to extend upward, the portion of the handle unit 300 extending from both ends of the mold unit 100 and merging into one path may be formed to be tiltable.

On the other hand, the predetermined pattern may be formed on the outside of the mold unit 100, which may be formed to protrude outward of the mold unit 100 as shown in FIG. 8, but according to the manufacturer's intention It may be formed to be recessed inward, and may not be limited to whether or not the predetermined pattern protrudes.

In addition, since the hot wire unit 200 emits a temperature equal to or higher than the melting point of high-density polyethylene and transmits the temperature to the mold unit 100, the mold unit 100 moves along the processing area S1 while being rotated. It is possible to perform anti-slip processing according to the predetermined pattern formed in the intaglio or embossed shape on the panel (P) made of high-density polyethylene, which is the ship (B) using the panel (P). Since it has been manufactured, there may be an advantage that the waste carried out in processing can be significantly reduced compared to the prior art.

To briefly summarize the foregoing, the manufacturing method according to an embodiment of the present invention is to use the panel (P) made of high-density polyethylene for the ship (B), and use the panel (P) for the ship. After manufacturing (B), since the anti-slip processing is performed through the processing step (S40), the processing process can be shortened more effectively, and the part of the cut panel (P) that is not used for the ship (B) Since silver processing has not been performed, there may be an advantage in that it can be recycled more effectively if necessary.

Preferred embodiments according to the invention have been looked at, and the fact that the present invention can be embodied in other specific forms in addition to the above-described embodiments without departing from the spirit or scope is obvious to those skilled in the art. will be.

Therefore, the embodiments described above are to be regarded as illustrative rather than restrictive, and thus the present invention is not limited to the above description, but may vary within the scope of the appended claims and their equivalents.
