Can be prevented.

The upper clamp 200 may include a plurality of vacuum suction ports (not shown). The vacuum suction port adsorbs the side surface of the window profile PF through a vacuum suction force transmitted from a vacuum pump (not shown). At this time, the vacuum suction port is formed on the bottom surface of the upper clamp 200 to adsorb the upper surface of the window profile PF. Since the vacuum suction port enables adsorption between the upper clamp 200 and the window profile PF, it is possible to prevent deterioration in appearance quality due to occurrence of a step, depression, sagging, etc. that may occur during a welding process.

The first extra blade portion 300 may be disposed on a pair of lower clamps 100 and a pair of upper clamps 200. The first extra blades 300 protrude to face each other and may extend parallel to each other. The first extra blade portion 300 is made so that the top or bottom protrudes sharply to cut off the swelling, and may be formed on the entire surface of the lower clamp 100 and the upper clamp 200. The first extra blade portion 300 may be formed on one surface of the lower clamp 100 and the upper clamp 200 facing each other.

When the stepped surface 315 connecting the first surface 310 and the second surface 320 is in contact with the upper end of the support frame 520 as the support frame 520 moves, the support frame 520 moves. Can be limited. That is, the support frame 520 moves up and down along the inclined surface of the first extra blade 300 by the mini cylinder rod 540. Further, the stepped surface 315 may act as a stopper with respect to the support frame 520 by limiting the movement of the upper surface of the support frame 520.

The sacrificial portion 400 may be inserted between the first elongated portions 300 disposed to face each other by moving along the length direction of the first elongated portion 300. The horizontal finishing blade 410 of the finishing part 400 may be in contact with the auxiliary blade 530 of the second blade part 500 to remove the swelling S formed in the window profiles PF.

Swelling (S) is the end of the window profile (PF) is melted as the window profile (PF) is heated by the heating plate (40), and the molten window profile (PF) protrudes out of the surface of the window profile (PF). Means part (see Fig. 6A).

Specifically, while the window profiles PF facing each other are pressed against each other, a portion of the molten window profile PF may protrude outside the surface. At this time, when the swelling S protruding outside the surface of the window profile PF is hardened, a welding burr may be formed.

On the other hand, the roller 51 is disposed in parallel with the horizontal finishing blade 410, the roller 51 may be disposed behind the horizontal finishing blade 410 as viewed based on the traveling direction of the finishing part 400. The roller 51 may move together with the horizontal finishing blade 410 as the finishing part 400 moves. Therefore, after the horizontal finishing blade 410 of the finishing part 400 removes the swelling S, the roller 51 of the second blade part 500 removes and presses the remaining swelling. .

Referring to FIGS. 4A and 4B, the second blade part 500 according to an embodiment of the present invention may include a housing 510, a support frame 520, and an auxiliary blade 530. The second extra blade 500 may be drawn into the interior of the window profile PF in a state in which a part of the window profile PF is melted by contacting the window profile PF with the heating plate 40. In this way, the second extra blade 500 is inserted into the fused window profile PF, and the swelling S may be cut by contact with the horizontal finishing blade 410. The cutting process of the swelling S by the second extra blade 500 and the horizontal finishing blade 410 will be described later.

The housing 510 may be coupled to an upper clamp or a lower clamp to support the support frame 520 and the auxiliary blade 530.

The support frame 520 may be movably coupled to the housing 510. The support frame 520 may move by being in contact with the first blade part 300 while supporting the auxiliary blade 530. Specifically, the support frame 520 may move in contact with the second surface 320 of the first extension part 300. As the support frame 520 moves up and down, the auxiliary blade 530 mounted on the support frame 520 may also move up and down.

The auxiliary blade 530 may include a tip 532 that is detachably coupled to the support frame 520 and can be inserted into the melting window profile PF. The tip 532 of the auxiliary blade 530 may move in contact with the first surface 310 of the first blade part 300. That is, the first surface 310 may serve as a guide when the tip 532 moves. At this time, the tip 532 may cut the swelling S by contacting the horizontal finishing edge 410 of the finishing part 400 in the process of assembling the window profile PF.

According to the movement of the mini-cylinder rod 540 for moving the support frame 520, the tip 532 of the auxiliary blade 530 may be retracted into the interior of the window profile PF. Specifically, the auxiliary blade 530 may be introduced into the interior of the window profile PF in a state in which the end of the window profile PF is in contact with the heating plate 40, and a part of the end of the window profile PF is melted. have.

The second extra blade portion 500 may include a side guide 550 disposed to support a side portion of the support frame 520. The side guide 550 may protrude from the first extra blade 300 or may protrude from the upper clamp and the upper clamp.

The side guide 550 is applied to an external force that the support frame 520 and the auxiliary blade 530 receive in a direction perpendicular to the moving direction along the first blade part 300 of the support frame 520 and the auxiliary blade 530. Flow can be reduced. For example, the support frame 520 and the auxiliary blade 530 is an external force received when the window profile PF is bonded or separated from the heating plate 40, or the horizontal finishing blade 410 is in contact with the auxiliary blade 530. When the swelling (S) is cut, the side guide 550 may reduce the external force that the auxiliary blade 530 receives.

Hereinafter, a window profile welding method according to an embodiment of the present invention will be described.

5 is a flowchart of a welding method using a window profile welding apparatus according to an embodiment of the present invention. 6A to 6G are views showing a process of welding the profile while removing the swelling of the second edge portion and the finishing portion of the window profile welding apparatus.

5 to 6G, according to the window profile welding method according to an embodiment of the present invention, first, the window profile PF is fixed between the lower clamp and the upper clamp disposed vertically on both sides (S10). ).

In this case, the profile PF may protrude further to the outside by a predetermined thickness d1 than the first blade part 300 and the tip 532 of the auxiliary blade part (see FIG. 4A). The thickness d1 may be about 1.8 mm or more and 3 mm or less. This is for melting a part of the profile by the heating plate 40.

The upper clamp 200 presses the window profile PF placed on the lower clamp 100, so that the window profile PF is fixed between the lower clamp 100 and the upper clamp 200. In this case, the window profile PF may be more strongly fixed to the lower clamp 100 and the upper clamp 200 by the vacuum suction ports of the lower clamp 100 and the upper clamp 200 described above.

6A, before the window profile PF is melted by the heating plate 40, the auxiliary blade 530 may be disposed close to the end of the first blade 300, that is, the surface of the profile PF. have. That is, when the window profile PF is fixed between the lower clamp 100 and the upper clamp 200, the auxiliary blade 530 may be disposed close to the surface of the profile PF.

Next, the heating plate 40 enters between the window profiles PF, and the window profile PF may be melted by the heating plate 40 (S20).

The window profile PF fixed between the lower clamp 100 and the upper clamp 200 is brought close to each other by the main driving means 32 and the auxiliary driving means 32'. And the end of the profile PF is heated as it contacts the heating plate 40 input from the rear between the pair of lower clamps 100 and between the pair of upper clamps 200 to form a swelling (S). . In this case, the auxiliary blade 530 may be pushed away from the window profile PF by the window profile PF. Accordingly, the mini-cylinder rod 540 may press the auxiliary blade 530 with a low pressure so that the auxiliary blade 530 is not pushed.

Referring to FIG. 6B, the auxiliary blade 530 of the second blade part 500 may move along the first blade part 300 to be inserted into the molten window profile PF (S30).

The mini-cylinder rod 540 of the second blade part 500 presses the auxiliary blade 530 with high pressure, so that the auxiliary blade 530 may be inserted into the window profile PF. At this time, the auxiliary blade 530 may press the wrapping paper (L) to audit the surface of the profile (PF).

Since the auxiliary blade 530 is inserted into the window profile PF, the distance d2 between the heating plate 40 and the auxiliary blade 530 may become closer. Through this, the thickness of the swelling S to be cut between the horizontal finishing blade 410 and the auxiliary additional blade 530 to be described later is reduced. Therefore, the horizontal finishing edge 410 can cut the swelling (S) more easily.

Referring to FIG. 6C, after the auxiliary blade 530 is inserted into the window profile PF, the heating plate 40 may be removed from the window profile PF (S40).

In this case, the auxiliary blade 530 may be maintained while being inserted into the interior of the window profile PF. As the heating plate 40 moves away from the window profile PF, the temperature at the end of the window profile PF decreases. As the auxiliary blade 530 is maintained inside the window profile PF, the heated end of the window profile PF is also deprived of heat by the auxiliary blade 530. Accordingly, the temperature at the end of the window profile PF may drop rapidly. Meanwhile, as described above, since the thickness between the end of the window profile PF and the auxiliary blade 530 is thin, the amount of heat received by the end of the window profile PF may also be reduced.

Next, referring to FIG. 6D, both sides of the window profile PF may be pressed against each other (S50). In this case, the interval between the lower clamps supporting the window profile PF may be controlled as the first interval.

In the above-described step, the heating plate 40 is moved to the rear between the lower clamp 100 and the upper clamp 200. That is, the heating plate 40 is removed between the lower clamp 100 and the upper clamp 200.

Then, the profiles PF are pressed toward each other by the main driving means 32 and the auxiliary driving means 32'. In this case, the ends of the window profile PF may protrude outside the upper and lower surfaces of the window profile PF by the force that the ends of the window profile PF are pressed against each other. This protruding part forms a swelling (S).

At this time, since the auxiliary blade 530 is maintained inside the window profile PF, the gap d3 between the auxiliary blade 530 and the auxiliary blade 530 is reduced. In this case, the distance d3 between the auxiliary blade 530 and the auxiliary blade 530 may be 0 to 2 mm or less.

In this way, since the thickness of the swelling S becomes thin, cutting by the horizontal finishing blade 410 can be easily performed.

Next, referring to FIGS. 6E and 6F, the swelling (S) may be removed by the finishing part 400 in contact with the auxiliary blade 530 (S60).

The sacrificial part 400 enters between the auxiliary blades 530 facing each other so that the sacrificial part 400 comes into contact with the auxiliary blade 530. At this time, the position (L2) at which the swelling (S) is cut in contact with the auxiliary edge (530) by the finishing part (400) is located inside the window profile (PF) based on the surface (L1) of the window profile (PF). do.

More specifically, the horizontal finishing blade 410 of the finishing part 400 may meet the tip 532 of the auxiliary blade 530 located inside the window profile PF to cut the swelling (S). At this time, the position at which the swelling S of the molten window profile PF is cut is a point L2 where the tip 532 of the auxiliary blade and the horizontal finishing blade 410 meet. The swelling (S) exiting between the horizontal finishing blade 410 and the auxiliary blade 530 is cut by the horizontal finishing blade 410 and the auxiliary blade 530.

Next, referring to FIG. 6G, the auxiliary blade 530 may be drawn out of the surface of the window profile PF (S65). Before the step in which the window profiles PF are pressed again with each other, the auxiliary blade 530 is drawn out of the surface of the window profile PF and may be disposed at a position L3 lower than the surface of the profile PF. Through this, when the window profiles PF are pressed again with each other, interference by the auxiliary blade 530 may be prevented.

Then, the window profiles PF on both sides may be pressed again in a direction facing each other (S70). In this case, an interval between the lower clamps supporting the window profile PF may be controlled as a second interval rather than the first interval.

As the lower clamp 100 facing each other and the upper clamp 200 facing each other become closer, the window profiles PF on both sides may be pressed again. Thereby, the swelling S between the window profiles PF can be cut to fill the gaps generated, and the welding between the window profiles PF can be achieved more firmly.

In this process, the lower clamp 100 and the first extra blade 300 protruding from the upper clamp 200, which were spaced apart from each other, may be bonded to each other or disposed very close to each other. That is, the first extension parts 300 may be in contact with each other, or may be disposed at a position in which the distance between the first extension parts 300 converges close to zero.

From the step (S30) in which the auxiliary blade 530 is drawn into the inside of the molten profile (PF) to the step (S40) of removing the swelling (S), the tip 532 of the auxiliary blade 530 is a window profile ( PF) can still be located inside. Accordingly, the distance between the end of the window profile PF and the auxiliary blade 530 is reduced, so that the cutting of the swelling S can be used. In addition, it is possible to reduce the protrusion of the swelling S of the window profile PF to the outside.

Here, the step of removing the swelling (S) by contacting the sacrificial part 400 with the auxiliary blade 530 (S60) and the step of re-pressing the window profiles PF on both sides in a direction facing each other (S70) In the meantime, it will be described that the auxiliary blade 530 is drawn out of the surface of the window profile PF in advance. However, it is not necessarily limited thereto, and in the step (S70) in which the window profile PF is pressed, the auxiliary blade 530 is continuously disposed inside the window profile PF, and the window profiles PF on both sides are mutually As the pressure is applied, the auxiliary blades 530 may naturally come down to the bottom while contacting each other. At this time, the pressure applied to the mini-cylinder rod 540 of the second blade portion 500 is reduced so that the auxiliary blade 530 naturally descends downward.

Thereby, when the auxiliary blade 530 comes down to the bottom while in contact with each other, the auxiliary blade 530 continues to press the surface of the window profile PF, so that the swelling S that protrudes to the outside of the window profile PF or It is possible to reduce the occurrence of welding burrs.

According to the window profile (PF) welding apparatus according to an embodiment of the present invention, by cutting the swelling (S) in contact with the auxiliary blade 530 of the second blade portion 500, the horizontal finishing blade 410, When abrasion of the auxiliary blade 530 occurs, only the auxiliary blade 530 needs to be replaced. Accordingly, the maintenance cost can be reduced compared to that of having to replace the entire first blade part 300. In addition, since only the auxiliary blade 530 needs to be replaced, the difficulty and time of repair can be reduced.

Furthermore, since the auxiliary blade 530 cuts the swelling (S) inside the horizontal finishing blade 410 and the window profile (PF), the amount of swelling (S) remaining after cutting is reduced, as well as the remaining It is possible to reduce the occurrence of quality deterioration as the swelling (S) flows out of the surface of the window profile (PF).

As described above, one embodiment of the present invention has been described, but those of ordinary skill in the relevant technical field add, change, delete or add components within the scope not departing from the spirit of the present invention described in the claims. It will be possible to variously modify and change the present invention by the like, and it will be said that this is also included within the scope of the present invention.
