Thermal welding device for window frame processing having a cutting unit capable of minimizing the bead protruding from the profile joint surface of the window frame and aligning the stepped groove part of the profile accommodating the bead to the virtual joint surface of the profile to form it with high precision provides The thermal welding device for window frame processing includes a profile fixing frame and a profile moving frame installed on a table, supporting the ends of the profile at right angles to each other and fixing the ends of the profile to be in contact with or spaced apart from each other by a predetermined distance, and the profile fixing frame and a guide plate that advances and retreats between the profile moving frames and aligns the provisional joining portions of each profile supported on the profile fixing frame and the profile moving frame, and the contact line at the position where the temporary joining portions of the profiles aligned by the guide plate are in contact with each other. Accordingly, a cutting unit for cutting each profile end to a predetermined width and depth, and a heating plate for advancing and retreating between the profile fixing frame and the profile moving frame to fuse the temporary joint surface of each profile cut at the end.

However, when a window is manufactured with such an existing welding device, the following problems occur.

(1) A wide welding line is formed on the surface where two adjacent profiles constituting the window and door are in contact with each other, thereby reducing the quality of the window.

(2) That is, since both ends of two adjacent profiles facing each other are melted with a hot plate and then forcibly joined by pressing, a bead is formed on the surface to be joined. And as the bead formed like this is scraped off using a chisel, an intaglio line (welding line) is created.

(3) At this time, if the welding line is scraped not too deep, the bead remains around the joint surface of the profile and the aesthetics and quality are impaired. In addition, since the remaining beads have to be scraped off again through post-processing, not only the working time is long, but also the manufacturing cost is increased.

(4) Therefore, as the bead is removed a little deeply when scraping with a chisel, the bead can be scraped off almost completely, but the tip of the chisel is scraped to the inside of the joint surface of the profile, so that the welding line is visible from the outside.

(5) Therefore, when welding two adjacent profiles, the width of the welding line on the welding surface must be minimized so that the work can be finished at once without post-processing.

(6) On the other hand, the profile used for manufacturing windows

First, as shown in [Fig. 6], a chin (S) is formed on the profile (P) in which both ends are cut diagonally. To this end, when the profile P is placed on the support block 420, the actuator 430 is controlled to fix the profile P, and then the milling 440 is controlled to control the two adjacent profiles P', When welding P"), at least the part exposed to the indoor side of the inner edge is cut off to form the jaw (S).

Then, as shown in [Fig. 8] and [Fig. 9], between the two adjacent profiles (P', P") placed on the two fixed clamping means 300' and the two movable clamping means 300". The heating plate 340 is placed on the surface to melt the opposite sides of the profiles P' and P", and then the third actuator 321 is operated to make these fixed and movable clamping means 300' and 300" The profiles P' and P" are pressed. Accordingly, the bead (B) is formed to protrude out of the line portion (welding line) formed by joining the profiles P' and P" to each other.

Then, as shown in [Fig. 10], the chisel 360 cuts off the bead (B) while following the welding line where the bead (B) is generated. At this time, if the depth of the chisel 360 is not deep, the bead (B) can remain along the welding line, so the edge of the end goes into the surface of the profile (P', P"), but the welding line is not as deep as possible. It is preferable to cut off the bead (B) while following.

Next, as shown in Fig. 11, the fourth actuator 341 is actuated so that no force is applied to the profiles P' and P". This includes the fixed clamp means 300' and the movable Since the clamping means 300" cannot be compressed with a uniform force when compressed due to friction, etc., as will be described later, when the profiles P' and P" are momentarily pressed again to minimize the welding line, these clamping means This is to minimize friction that may be caused by

In a preferred embodiment of the present invention, when removing the force applied by the fourth actuator 341, removing the force applied until the pressure applied to the profiles (P', P") becomes 0 kg/cm2 Preferably, in this case, it is preferable to use an electronic pressure gauge to confirm how much force is applied to the profiles (P', P").

Finally, as shown in [Fig. 12], the third actuator 321 is operated again to operate the fixed clamping means 300' and the movable clamping means 300". At this time, these fixed clamping means ( 300') and the movable clamping means 300" as described above remove the force applied to the profiles P' and P" and press the profiles P' and P" again at the same time to remove the beads. Control the welding line to be minimized while making the engraved lines stick together.

In a preferred embodiment of the present invention, the width W for filling the intaglio line by moving the fixed clamping means 300' and the movable clamping means 300" is most preferably controlled to move by 0.1 to 3 mm. Of course, it is more desirable to reflect the size change of the window caused by this movement in the length of the profile at the design stage.

The present invention made as described above melts the both ends of the adjacent two profiles and then presses the profile once again to the intaglio line formed when removing the bead generated during welding to fill the intaglio line, thereby remarkably reducing the welding line, and also When one or two profiles are welded, the welding line of the part exposed to the interior of the inner edge can be remarkably reduced, so the aesthetics and aesthetics of the window can be improved, and as a result, the quality can be further increased.

The welding machine for plastic windows with a minimized welding line according to [Example 2] of the present invention, as shown in [FIG. There is a difference. Accordingly, the detailed description of the same configuration as in the above-mentioned [Embodiment 1] will be omitted and the difference configuration will be mainly described.

[Embodiment 2] is configured by adding a fifth actuator 370 as shown in [Fig. 13]. Here, the fifth actuator 370 is mounted on the actuating block 322, and in particular, by directly pushing and pressing the profiles P', P", using a clamping means, the profiles P', P" ) is fixed or supported, and the intaglio line is filled by directly pressing the profile (P', P") while preventing friction from occurring, so to fill the intaglio line, the profile (P', P") The width (W) control that moves the

Therefore, the present invention can eliminate the intaglio line by directly pressing the profile in which the intaglio line is generated, thereby further minimizing the welding line.
