Occurs. Accordingly, there is a problem that the quality of the appearance of the window frame and the window leaf is deteriorated.

In order to solve this problem, a separate operation of removing the welding line after welding of the window profile is performed, or an attempt is made to develop a window profile welding device to reduce the occurrence of the welding line due to swelling.

As shown in Fig. 23, after removing the swelling (S1) with the finishing machine (1), a method of pulling the swelling (S1) into the inside of the profile (PF) using the blade of the clamp (3) is taken. As shown in FIG. 23 (c), the removed and remaining swelling (S2) or the wrapping paper on the surface of the profile (PF) protrudes out of the joint of the profile (PF), resulting in a problem of deteriorating appearance quality.

In the step of removing the pressing force (S204), the gap between the lower clamps 100 may be maintained using the stopper cylinder 60. That is, the lower clamps PF may be supported by the stopper cylinder 60 to prevent further advancement in the pressing force removal step (S204).

In addition, the pressing force removal step (S204) may remove the pressing force by discharging air from the main driving means 32 made of a pneumatic cylinder. In addition, in the step of removing the pressing force (S204), the pressure applied to the profile PF may be removed by separating the upper clamps 200 from the profile PF.

As shown in FIGS. 12 and 13A, in the mapping processing step S205, the swelling S1 protruding by primary pressure is removed by using the mapping portion 410. In the finishing processing step S205, the finishing part 610 may cut the swelling S1 while moving in the direction in which the swelling S1 is continued by the finishing support part 620. In the finishing processing step (S205), the swelling (S1) is removed at the point where the tip of the main blade 300 of the lower clamp 100 and the upper clamp 200 and the finishing part 610 meet, but the swelling is installed so as not to rotate. The part 610 removes the swelling (S1) while making surface contact with the main blade 300. To this end, the inclination angle of the tip of the sacrificial part 610 may be formed equal to the inclination angle of the main blade 300.

In other words, unlike the case of removing the swelling (S1) when only a part of the finishing part 610 is in contact with the main blade 300, the stress is dispersed as the entire surface contacting the finishing part 610 is in contact with the main blade 300. There is an advantage that the wear of the main blade 300 is delayed.

In addition, the surface temperature of the swelling (S1) in contact with the swelling (S1) according to the present embodiment is further increased so that the surface temperature of the swelling (S1) in contact with the swelling (S1) decreases faster, and the swelling ( The hardening of the surface of S1) can be accelerated to minimize thermal deformation.

By adjusting the height of the swelling pressurizing unit 720, the pressure at which the swelling pressurizing unit 720 presses the swelling S1 may be adjusted.

When the swelling pressing unit 720 applies excessive pressure to the swelling S1, the swelling S1 may be excessively introduced into the profile PF. In this case, even if the secondary pressure between the profiles PF is performed, the welded portion between the profiles PF may be concave.

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 830 may be pushed away from the window profile PF by the window profile PF. Therefore, the mini-cylinder rod 840 may press the auxiliary blade 830 with a low pressure so that the auxiliary blade 830 is not pushed.

Referring to FIG. 21B, the auxiliary blade 830 of the auxiliary blade part 800 may move along the main blade 300 to be introduced into the molten window profile PF (S403).

The mini-cylinder rod 840 of the auxiliary blade part 800 presses the auxiliary blade 830 with high pressure, so that the auxiliary blade 830 may be brought into the interior of the window profile PF. In this case, the auxiliary blade 830 may press the wrapping paper L to audit the surface of the profile PF.

As the auxiliary blade 830 is introduced into the window profile PF, the distance d2 between the heating plate 40 and the auxiliary blade 830 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 830 to be described later is reduced. Therefore, the horizontal finishing edge 410 can cut the swelling (S) more easily.

Referring to FIG. 21C, after the auxiliary blade 830 is inserted into the window profile PF, the heating plate 40 may be removed from the window profile PF (S404).

In this case, the auxiliary blade 830 may be maintained while being inserted into 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. While the auxiliary blade 830 is maintained inside the window profile PF, the heated end of the window profile PF is also deprived of heat by the auxiliary blade 830. 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 830 is thin, the amount of heat received by the end of the window profile PF may also be reduced.

Next, referring to FIG. 21D, both sides of the window profile PF may be pressed against each other (S405). In this case, an interval between the lower clamps 100 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 830 is maintained inside the window profile PF, the distance d3 between the auxiliary blade 830 and the auxiliary blade 830 is reduced. In this case, the distance d3 between the auxiliary blade 830 and the auxiliary blade 830 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. 21E and 21F, the mapping part 400 may contact the auxiliary blade 830 to remove the swelling S (S406).

The sacrificial part 400 enters between the auxiliary blades 830 facing each other so that the sacrificial part 400 comes into contact with the auxiliary blade 830. At this time, the position (L2) at which the swelling (S) is cut in contact with the auxiliary blade (830) of 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 832 of the auxiliary blade 830 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 front end 832 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 830 is cut by the horizontal finishing blade 410 and the auxiliary blade 830.

Next, referring to FIG. 21G, the auxiliary blade 830 may be drawn out of the surface of the window profile PF (S407 ). Before the step in which the window profiles PF are pressed again with each other, the auxiliary blade 830 may be 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 due to the auxiliary blade 830 may be prevented.

Then, the window profiles PF on both sides may be pressed again in a direction facing each other (S408). In this case, the interval between the lower clamps 100 supporting the window profile PF may be controlled as a second interval smaller than the above-described 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 main 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 main blades 300 may contact each other, or may be disposed at a position where the distance between the main blades 300 converges close to zero.

From the step (S403) in which the auxiliary blade 830 is drawn into the inside of the molten profile (PF) to the step (S404) of removing the swelling (S), the tip 832 of the auxiliary blade 830 is a window profile ( PF) can still be located inside. As a result, the gap between the end of the window profile PF and the auxiliary blade 830 is reduced, so that 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 830 (S406) and a step in which the window profiles PF on both sides are pressed again in a direction facing each other (S408) In the meantime, it will be described that the auxiliary blade 830 is drawn out of the surface of the window profile PF in advance. However, it is not necessarily limited thereto, and in the step (S408) in which the window profile PF is pressed, the auxiliary blade 830 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 830 may naturally come down to the bottom while contacting each other. At this time, the pressure applied to the mini-cylinder rod 840 of the auxiliary blade portion 800 is reduced so that the auxiliary blade 830 naturally descends downward.

Thereby, when the auxiliary blade 830 comes in contact with each other and descends downward, since the auxiliary blade 830 continues to press the surface of the window profile PF, 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, the auxiliary blade 830 of the auxiliary blade portion 800 contacts the horizontal finishing blade 410 to cut the swelling (S), thereby assisting When abrasion occurs on the extra blade 830, only the auxiliary blade 830 needs to be replaced. Accordingly, maintenance cost can be reduced compared to that of having to replace the entire main blade 300. In addition, since only the auxiliary blade 830 needs to be replaced, the difficulty and time of repair may be reduced.

Further, since the auxiliary blade 830 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 means of the like, and it will be said that this is also included within the scope of the present invention.
