DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pair of synthetic resin shaped members constituting a synthetic resin frame such as a window frame, a fitting, or a picture frame used for construction, which are cut at 45 degrees. The present invention relates to a device for removing a weld tension generated at a welded portion where a right angle is welded.

[0002]

2. Description of the Related Art When manufacturing synthetic resin frames such as window frames, fittings, picture frames and the like, the ends of synthetic resin profiles are welded at right angles as follows. First, the end portion of the synthetic resin shaped material is cut at 45 degrees, the cut surfaces are butted together and welded in a molten state by a heating means. When welding is performed in this way, a welding tension occurs at the welding portion,
It is necessary to remove this welding tension.

[0003] As a device for removing the welding tension generated at the welded portion as described above, for example, a device disclosed in Japanese Patent Publication No. 3-8887 is known. In other words, while rotating the conical rotary blade having a vertical angle of about 76 degrees, the rotary shaft is inclined and moved along the welded portion to scrape off the welding tension.

[0004]

In such a device for removing the welding tension, since the cutting is performed by rotating the rotary blade, the surface accuracy of the cut surface is not very good, and there is a risk of shaving the surface of the shaped material. It is scraped off with a slight distance from the profile surface, and the welded tension after cutting slightly protrudes from the profile surface. For this reason, in the case of the above-mentioned scraping using the rotary blade, it is necessary for the operator to finish the work by hand after the scraping, and the work of removing the welded tension becomes troublesome.

Accordingly, an object of the present invention is to provide a synthetic resin frame welding and removing apparatus which can solve the above-mentioned problems.

[0006]

Means for Solving the Problems An end 1a of a synthetic resin profile 1 is cut at 45 degrees, and the ends of the synthetic resin frame 1 are welded at right angles.

And a frame moving mechanism E having a roller 33 that moves toward the center of the frame positioning portion D, and a first attachment body movably provided on the body A in the vertical direction and toward the center of the frame positioning portion D. A second mounting body attached to the first mounting body movably in the left-right direction and held at a middle position in the left-right direction by a spring; and a pair of left and right positioning mounted on the second mounting body A piece and the second mounting body,
It has a cutter attached to the center of the frame positioning portion D so as to be reciprocally movable. The front surface of the pair of left and right positioning pieces is 45 degrees, and the intersection extending from the front surface matches the center of the frame positioning portion D. A welding and removing apparatus for a synthetic resin frame.

[0007]

[Operation] The synthetic resin frame a is temporarily placed on the frame positioning portion D of the machine body A, and the rollers 33 of the frame moving mechanism E are moved up and down to protrude into the synthetic resin frame a. By moving toward the center of the frame positioning portion D, the roller 33 comes into contact with the inner surface of the corner b of the synthetic resin frame a, and the outer surface of the corner b of the synthetic resin frame a is pressed against the frame positioning portion D. The synthetic resin frame a is positioned and held. Thereafter, the first mounting body is moved up and down to protrude into the synthetic resin frame a, and the second mounting body is moved together with the first mounting body toward the center of the frame positioning portion D to form a pair. The front surface of the positioning piece abuts on the inner surface of two adjacent synthetic resin profiles 1 with the corner b of the synthetic resin frame a as a boundary, and the second mounting body moves to one of the right and left against the spring. The second mounting body is positioned with respect to the synthetic resin frame a, and the cutter faces the corner b of the synthetic resin frame a. Thereafter, the welded tension generated at the corner b of the synthetic resin frame a by moving the cutter is cut and removed. Because of this, the synthetic resin frame a can be positioned and held on the body A by the frame positioning portion D and the frame moving mechanism E, and the second mounting member can be positioned with respect to the synthetic resin frame a and the cutter can be positioned. Can be positioned toward the corner b of the synthetic resin frame a, so that the welded tension at the corner b of the synthetic resin frame a can be easily and accurately cut and removed.
