Also, referring to FIG. 5,

It includes a flange portion formed to couple the two members 101 and 102 and a bonding surface 105 and 106 that is one surface of the flange portion, and the bonding surfaces 105 and 106 are positioned to face each other, and the bonding surface A heater is inserted between (105, 106) to contact and melt both sides of the heater surface inserted between the facing bonding surfaces (105, 106) and the bonding surfaces (105, 106), and then separate the heater. It is an exemplary view showing a device for extracting and bonding by pressing the molten bonding surfaces 105 and 106 to abut each other and a configuration using the same.

Looking at this in detail,

A pair of jig frames (210, 220) accommodated in the pair of members (101, 102), and the members accommodated in the jig (210, 220) have a bonding surface (105, 106) facing each other. It is arranged to see.

In addition, guide portions 230 and 240 corresponding to the concave groove portions 111 and 112 formed in the member so that the accommodated members 101 and 102 can be seated in the correct position are formed in the jig frames 210 and 220. There,

When receiving the members 101 and 102 in the jig frames 210 and 220, the concave grooves 111 and 112 formed in the members 101 and 102 are guided and accommodated by the guide parts 230 and 240. Fixed in position.

In addition, the jig frames 210 and 220 are formed to be movable so as to be accommodated and pressurized using a cylinder operated by hydraulic or pneumatic pressure.

In addition, the heater 300 is inserted between the bonding surfaces 105 and 106 of the member, so that both surfaces of the heater and the bonding surfaces 105 and 106 contact and melt.

In addition, when the bonding surfaces 105 and 106 in contact with the heater 300 are melted, the heater 300 is separated between the bonding surfaces 105 and 106 of the members inserted into the jigframes 210 and 220. Then, the jig molds 210 and 220 are fused and bonded by pressing the inserted bonding surfaces 105 and 106 in a melted state.

In addition, it can be seen that the configuration further includes a pressing member 250 for separating and extracting the fusion-bonded buoy 100 from the jig frames 210 and 220.

In addition, a protrusion 107 and a concave portion 108 are formed on the bonding surfaces 105 and 106 so as to increase the contact area to be fused, and a protrusion of the bonding surface ( The concave portion 109 and the protrusion 110 corresponding to the concave portion 107 and the concave portion 108 may be formed, and the protrusion and the concave portion may be changed into various shapes to be symmetrical to each other.

In addition, the joining portions 103 and 104 of the member form a flange portion protruding outward along the edge of the space portion so as to increase the joining area, and include joining surfaces 105 and 106 that are one surface of the flange portion. do.

In addition, by positioning the bonding surfaces 105 and 106 to face each other, and inserting a heater between the bonding surfaces 105 and 106, the heated both surfaces of the inserted heater and the bonding surfaces 105 and 106 After melting, the heater may be separated and extracted, and the melted bonding surfaces 105 and 106 may be pressed and bonded to abut each other.

In addition, looking at the optimal fusion method using the jig frame (210, 220),

The surface temperature of the heater 300 used for fusion in the jig molds 210 and 220 is 450°C to 700°C, and the contact time between the heater 300 and the bonding surfaces 105 and 106 is 2 to 3 seconds,

When the heater 300 is separated and extracted after the elapse of the contact time, it is possible to select an optimal condition to pressurize within 0.2 to 0.3 seconds to fusion bond,

When the heater 300 is separated and extracted between the bonding surfaces 105 and 106 after the elapse of the contact time, it is fused and bonded by pressing within 0.2 to 0.3 seconds.

The optimum condition as described above is that if the surface temperature of the heater 300 used for the fusion is set to 450°C or less, the time for the bonding surfaces 105 and 106 inserted in the jigframes 210 and 220 to melt becomes longer. Of course, the bonding surfaces 105 and 106 are not melted appropriately for fusion, and the bonding strength is weakened even if the bonding surfaces that are not suitable for melting are pressed and fused together.

In addition, when the surface temperature of the heater 300 is 700° C. or higher, the bonding surfaces 105 and 106 inserted in the jig frames 210 and 220 melt more than necessary due to the high temperature, and the bonding surfaces 105 and 106 The molten liquid melted in is attached to the heater surface or flows down.

Therefore, the optimum surface temperature of the heater 300 used for fusion is 450°C to 700°C, and by selecting the temperature of the heater 300, the contact time between the heater and the bonding surfaces 105 and 106 is determined by the heater 300 ) Depending on the surface temperature, you can select a time between 2 and 3 seconds, and when the contact time elapses and the bonding surfaces 105 and 106 are melted, the heater 300 inserted between the bonding surfaces 105 and 106 ) Is separated and extracted.

In addition, when the heater is extracted, the jigtle moves so as to contact the molten bonding surface within 0.2 to 0.3 seconds using a cylinder operated by hydraulic or pneumatic pressure, and pressurizes to fusion bond.

When the heater 300 is separated and extracted as described above, 0.2 seconds of the conditions of pressurization within 0.2 to 0.3 seconds require a time to separate and extract the bonding surfaces 105 and 106 in contact with the heater, and pressurization within 0.3 seconds is melted. It is selected to pressurize by contacting the molten surface before the contact surface is cooled.

In addition, when fused with the above pressure, it is known that the buoy is completed by extracting and carrying out the buoy fixed to the jigtle (210, 220) after cooling by naturally cooling or by blowing. I can.

The size of the buoy 100 manufactured in this way is 600 mm in length and 400 mm in diameter, the thickness of the buoy body is 3 mm, the height of the semi-circular rib is 3 mm, the thickness of the partition member is 3 mm, the coupling part 103, 104) may have a thickness of 10 to 13 mm and a fusion bonded thickness of 20 to 25 mm, and these values can be manufactured in various sizes and thicknesses other than the optimal values.

In addition, since the buoy is used in the sea with strong sunlight, it must provide a UV blocking function, and the UV blocking method is to create a primer coating layer by applying a primer composed of a solvent, silane, and acetic acid on the surface of the buoy 100 bonded by heat fusion. .

In addition, after applying the first coating agent containing alumina powder on the surface of the buoy, it may be selected to apply a second coating agent containing a UV blocking agent to create a second coating layer to provide a UV blocking function.

In addition, the primer may be configured by mixing 450 to 550 parts by weight of a solvent and 2 to 4 parts by weight of acetic acid in 10 parts by weight of silane, and the first painting step uses spray painting, and the second painting step is electrostatic painting You can choose.

In addition, a luminous tape is attached or a luminous paint is applied to the surface of the buoy 100, which has a UV-blocking function, and is formed to form a band-shaped luminous reflector on the surface of the buoy. A luminous function can be added to emit light in a dark night by forming at regular intervals along the length direction.
