It is an exemplary view showing a device for extracting and pressing and bonding the melted bonding surfaces 105 and 106 so that they come into contact with each other, and a configuration using the same.

Looking at this in detail,

The pair of members (101, 102) is a pair of jigttle (210, 220) accommodated therein, and the member accommodated in the jigttle (210, 220), the bonding surface (105, 106) facing each other It is arranged to see.

In addition, guide parts 230 and 240 corresponding to the concave groove parts 111 and 112 formed in the member are formed in the jig frame 210 and 220 so that the accommodated members 101 and 102 are seated in the correct position. And

When the members 101 and 102 are stored in the jig frames 210 and 220, the concave groove parts 111 and 112 formed in the members 101 and 102 are guided and received by the guides 230 and 240, and are stored and accurately It is fixed in position.

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 are contacted and melted.

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 member inserted into the jig frame 210 and 220. Then, the jigttle 210 and 220 are fused and bonded by pressing the inserted joint surfaces 105 and 106 in a molten state.

In addition, it can be seen that the fusion-bonded buoy 100 further comprises a pressing member 250 for separating and extracting the jigsets 210 and 220.

In addition, protrusions 107 and recesses 108 are formed on the bonding surfaces 105 and 106 so as to widen the contact area to be fused, and protrusions of the bonding surfaces ( 107) and the concave portion 109 and the protrusion 110 corresponding to the concave portion 108 may be formed, and the protrusion and the concave portion may be changed into various shapes symmetrically to each other.

Of course, the joining surfaces 105 and 106 are not melted for fusion, and the joining strength is weak even when the joining surfaces for which melt is not suitable are pressed and fused.

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 molds 210 and 220 are melted more than necessary due to the high temperature and the bonding surfaces 105 and 106 In the molten melt 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 the heater 300 ) Can be selected between 2 and 3 seconds depending on the surface temperature, and when the contact time has elapsed and the bonding surfaces 105 and 106 are melted, the heater 300 inserted between the bonding surfaces 105 and 106 ).

In addition, when the heater is extracted, the jigttle is moved to abut the melted joint surface within 0.2 to 0.3 seconds using a cylinder operated by hydraulic pressure or air pressure, and is fusion-bonded by pressing.

As described above, when the heater 300 is separated and extracted, 0.2 seconds among the conditions for pressurizing within 0.2 to 0.3 seconds requires a time for separation and extraction of the contact surfaces 105 and 106 in contact with the heater, and pressing within 0.3 seconds melts. It was selected to contact and press the molten surface before the contact surface cooled.

In addition, after fusion by pressure as described above, the buoy is completed by extracting and exporting the buoy fixed to the jig frame 210 and 220 by pressing the member 250 after natural cooling or blowing the joint surface. Can be.

The fusion-bonded buoy 100 further includes ring-shaped reinforcing rings 120 and 130 formed of a metal material on both sides of the coupling portion, and the reinforcing rings on both sides of the coupling portion and the fixing portion formed on the coupling portion of the coupling portion A heat-sealed fixing buoy, characterized in that the bonding strength of the joint is increased by bundling or fixedly bonding with a steel material or a fixing string using the insertion portions 109 and 110.
The method of claim 6
A primer coating layer is formed by applying a primer composed of a solvent, silane, and acetic acid to the surface of the heat-bonded buoy 100,
A heat-sealed fixed buoy, characterized in that a first coating agent containing alumina powder is applied to the surface of the buoy, and then a second coating agent containing a UV blocking agent is applied to create a second coating layer to impart UV protection.
The method of claim 7
A luminous tape is attached to the surface of the buoy 100, which is heat-sealed and combined with a UV-blocking function, or is formed to form a band on the surface of the buoy by applying a luminous paint, but the reflective parts are spaced apart at regular intervals along the longitudinal direction of the buoy. Heat-sealed fixed buoy, characterized in that to form.
