In addition, in step S3 of injecting the heating plate, the heating plate 20 may be coupled to the Teflon-coated metal plate 21 on both sides.

Therefore, when the front end of the window and the synthetic resin profile 100 through the heating plate 20, the end of the window and the synthetic resin profile 100 in contact with the Teflon-coated metal plate 21 can be prevented from sticking. .

In addition, in the step of inserting the heating plate (S3), the heating plate 20 may be coupled to the interval maintaining block 22 of a predetermined width at the bottom.

Therefore, when cutting the swelling part 110 formed in the synthetic resin profile 100 for the window through the blade 13, the lower pressing piece 12 on one side and the other side of the gap maintaining block 22. The interval between the blades 13 between the upper pressing pieces 11 and 12 and the interval between the blades 13 between the lower pressing pieces 11 and 12 are constant as the stoppers 12a coupled to each other contact. In particular, since the spacing between the blades 13 is maintained to be equal to the thickness of the heating plate 20, the ends of each of the blades 13 may be closely adhered to the heating plate 30, so that the blades 13 Cutting of the swelling unit 110 may be smooth.

In the step S4 of forming the swelling part and simultaneously cutting the swelling part, each of the left and right clamps 10 is moved toward the heating plate 20 to contact the heating plate 20 with the synthetic resin profile for the window. The swelling portion 110 is formed at the tip 100 and the swelling portion 110 is partially cut through the blade 13.

In addition, the blade 13 formed on the upper pressing piece 11 of the left and right clamps 10 in the step S4 of forming the swelling part and simultaneously cutting the swelling part is the synthetic resin profile 100 for the window and door. Cutting the swelling portion 110 protruding to the upper surface of the upper side, and the blade 13 formed on the lower pressing piece 12 is the swelling portion protruding below the lower surface of the synthetic resin profile 100 for windows and doors The swelling portion formed at the end of the window synthetic resin profile 100 because only the swelling portion 110 remains on only one side of the window facing the synthetic resin profile 100, that is, side by cutting the (110) ( Even welding 110) can prevent generation of welding burrs.

Discharging the heating plate (S5) discharges the heating plate 20 from between the left and right clamps 10.

In the discharging of the heating plate (S5), the heating plate 20 is discharged from the left and right clamps by inserting the rod 31 " in a protruding state by operating the cylinder 30 " Can return to the state of.

In step S6, the swelling part is bonded to each other to further move each of the left and right clamps 10 in a previous movement direction to bond the swelling part 100 formed at the front end of the synthetic resin profile 100 for the window and door.

In the step S6 of joining the swelling parts as described above, the left and right clamps 10 may move in the lateral direction by riding the rails 15 by the appearance of the rod 31 of the cylinder 30 as described above. .

Seamless seam welding of the synthetic resin profile 100 for the window through a seamless welding method of the synthetic resin profile for the window according to the present invention will be described in detail as follows.

The window synthetic resin profile 100 is fixed to each of the left and right clamps 10 with the end cut at about 45 °.

And the end of the synthetic resin profile for the window 100 is heated by contact with the heating plate 20 is introduced between the left and right clamp 10, thereby the swelling portion 110 is formed.

Therefore, the left and right clamps 10 are moved laterally after returning the heating plate 20 to the position before the injection in the state where the swelling part 110 is formed at the end of the window profile synthetic resin profile 100. Specifically, when the gap between the left and right clamps 10 is narrowed, the swelling part 110 formed at the end of the window synthetic resin profile 100 is in contact with each other and is entangled with each other, thereby forming the window synthetic resin profile 100. Welding of the liver is made (see FIG. 6).

However, since the swelling part 110 formed at the end of the window synthetic resin profile 100 by contact with the heating plate 20 has a considerable width and height, the swelling part 110 is formed as it is. Welding between the synthetic resin profile 100 for windows and doors generates a welding burr of considerable width and height, which inevitably reduces the beauty of the appearance.

However, in the present invention, when the swelling part 110 is formed at the end of the window profile synthetic resin profile 100 by contact with the heating plate 20, the upper pressing piece 11 of the left and right clamps 10 is formed. The blade 13 formed on the blade 13 and the lower pressing piece 12 is formed is the swell protruding to the upper surface of the swelling portion 110, more specifically the synthetic resin profile 100 for the window and door Cutting the swelling portion 110 protruding below the lower surface of the ring portion 110 and the synthetic resin profile 100 for the window, as shown in Figure 9 the end of the synthetic resin profile for the window 100 is welded Only the minimum necessary swelling unit 110 remains so that welding burr generation is prevented even though welding between the synthetic resin profile 100 for windows and doors is made. The width and height of the welding burrs generated during the welding are extremely small, and thus the welding burrs are prevented from being generated, which is referred to as a seamless connection. Can be.

Meanwhile, when cutting the swelling part 110 formed at the end of the window synthetic resin profile 100 through the blade 13, the tip of the blade 13 contacts the heating plate 20 with excessive pressure. The blade 13 can be easily damaged.

However, in the present invention, the stopper 12a may be coupled to the bottom surface of the lower pressing piece 12 of the left and right clamps 10 (see FIG. 4), and the gap maintaining block 22 is disposed at the lower end of the heating plate 20. ) May be coupled to the bar, which is coupled to each of the lower pressing pieces 12 when cutting the swelling part 110 formed at the end of the window profile synthetic resin profile 100 through the blade 13. As the stopper 12a comes in contact with one side and the other side of the space keeping block 22, the gap between the blade 13 between the upper press pieces 11 and the blade 13 between the lower press pieces 12. Since the gap between the heating plate 20 is maintained to be the same as the thickness of the heating plate 20, excessive pressure action can be prevented during the contact of the blade 13 and the heating plate 20, thereby damaging the blade 13 Can be prevented.

In addition, since the contact between the blade 13 is made when the welding between the synthetic resin profile 100 for the window is made, thereby the blade 13 may be damaged.

That is, the contact between the blade 13 formed on the upper pressing piece 11 and the contact between the blade 13 formed on the lower pressing piece 12 when welding between the window and the synthetic resin profile 100 is made. Since this is done, the blade 13 may be damaged.

However, in the present invention, the blade 13 can be elastically supported by the spring 14, the contact between the blade 13 formed in the upper pressing piece 11 and the lower pressing piece 12 When the blade 13 is formed in contact with the blade 13 is elastically flow, more specifically can be pushed backward so that excessive pressure action between the blade 13 is prevented thereby damaging the blade 13 This can be avoided (see FIG. 7).

On the other hand, the contact between the blade 13 formed on the upper pressing piece 11 and the contact between the blade 13 formed on the lower pressing piece 12 when welding between the window and the synthetic resin profile 100 is made. Since the contact between the blades 13 formed on the upper pressing piece 11 and the contact between the blades 13 formed on the lower pressing piece 12, the upper surface of the synthetic resin profile 100 for the window and The swelling part 110 that may remain on the bottom surface may be cut.

In addition, when the swelling part 110 is formed by contacting the heating plate 20 with an end portion of the synthetic resin profile 100 for the window, the synthetic resin profile 100 for the window may be attached to the heating plate 20. .

However, in the present invention, the heating plate 20 may be coupled to the Teflon-coated metal plate 21 on both sides, the window for the window when heating the end of the synthetic resin profile 100 for the window through the heating plate 20 Since the end portion of the synthetic resin profile 100 comes into contact with the Teflon-coated metal plate 21, the stretching of the synthetic resin profile 100 for the windows and doors may be prevented by the heating plate 20.

As described above, in the seamless welding method of the synthetic resin profile for the window according to the present invention, as the left and right clamps 10 to which the synthetic resin profile 100 for the window is fixed, respectively, move toward the heating plate 20. The swelling part 110 is formed at the end of the synthetic resin profile 100 for the window and the contact part 20, and the swelling part 110 is partially cut by the blade 13. Since welding burrs are prevented when welding the swelling parts 110 formed at each end of the synthetic resin profile 100 to each other, the welding burr can be prevented, thereby improving the beauty of the appearance that can be seamlessly welded.

In the above, the present invention has been illustrated and described with reference to specific embodiments, but the present invention is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the technical spirit of the present invention.
