Abstract

The invention relates to a method and to a device for connecting at least two profiled parts (1), wherein the least two profiled parts (1) fixed to profile supports (2) that can be moved relative to each other are each melted at an end joining face (10) by means of a heating element (5) in a melting step and, after the heating element (5) has been removed, are pressed with the melted joining faces (10) against each other in a joining step, until the molten materials brought into contact with each other there cool down and solidify, forming a welded connection. In order to reliably avoid or reduce the occurrence or the development of a welding bead, according to the invention, in a separating step to be carried out before the joining step, a mating tool (6, 29) is led through the melt along a separating edge (9) of a limiting element (3), in order to separate the excess melt that has exited over the separating edge (9).

Abstract

The invention relates to a method and a device for connecting two profiled parts (1, 3) made of plastic, in particular made of a thermoplastic, wherein a joining surface (2) of one profiled part (1) is melted for connection to a joining surface (13) of the other profiled part (3) and at least one mould (4, 6) is moved relative to the one profiled part (1) so as to displace molten material (5) escaping at least at one edge portion (8) of the joining surface (2). The formation of a weld bead is intended to be prevented in the process, albeit at least the form thereof is intended to be effectively reduced. This is achieved in that the at least one mould (4, 6) is tilted around the edge portion (8) relative to the molten joining surface (2) of the one profiled part (1).

Abstract

The invention relates to a device (1) for connecting profiled parts (12) to profile supports which are arranged perpendicularly to one another and which have profile support receiving areas (2) for receiving and clamping the profiled parts (12). At least one profiled part (12) and a heating surface of a heating element of the device (1) can be brought into contact with each other in order to melt the at least one profiled part (12) in the profiled part welding region prior to joining with the other profiled part. A machining tool (3) is provided which has at least one molding part (4), by means of which a flow and deformation of a melt product on a visible surface of a profiled part (12) can be controlled. The aim of the invention is to provide an improved device (1) for connecting profiled plastic parts, said device preventing the aforementioned disadvantages while simultaneously configuring the discharge of the melt in a controllable manner such that a post-machining process can be completely or at least partly omitted. According to the invention, this is achieved in that the molding part (4) and the profile support receiving areas (2) form an angle (5) between 10° and 50° relative to each other, and the molding part (4) can be moved from a rest position in the direction of a working position relative to the profile support receiving area (2).

Abstract

The invention relates to a method for connecting profiled parts (2). At least one profiled part (2) and a heating surface (7) of a heating element (6) are brought into contact with each other in a joining direction in order to melt the at least one profiled part (2) in the welding region of the profiled part prior to a joining process together with the other profiled part (2). The aim of the invention is to provide an improved method and an improved device for connecting profiled plastic parts in corner regions of profiled sections (2) to be joined together, wherein even the discharge of the melt can be controlled and the shaping process of the welding region can be influenced during the connection process such that a reworking process can be completely or at least partly omitted. This is achieved in that delimiting elements (4) are used by means of which a flow and deformation of the melt product can be controlled. The delimiting elements (4) are moved towards each other at an angle of 15° - 180°, preferably at a right angle.

Abstract

The invention relates to a method for connecting plastic profile parts (2), wherein at least one profile part (2) and a heating area (34) of a heating element (36) are brought into contact with one another in a joining direction in order to make the at least one profile part (2) begin to melt in its welding region before it is joined together with the other profile part (2), wherein a delimiting element (7) that can be used for controlling the melted material as it flows and is deformed is provided, wherein the delimiting element (7) has at least one abutting element (21) and a moulding part (22), which are movable both in relation to one another and in relation to the profile part (2), wherein during melting of the at least one profile part (2) the abutting element (21) is moved together with the moulding part (22) out of a rest position in the direction of a working position in relation to the at least one profile part (2) and the heating element (36), wherein at least during the melting at least the moulding part (22) is held in contact with the heating area (34) of the heating element (36) and the abutting element (21) is held in contact with a profile surface (9). The invention is distinguished by the fact that, when there is a changeover from melting to compressing, the relatively movable abutting element (21) is moved together with the moulding part (22) in the direction of the working position in such a way that the delimiting element (7) projects beyond a free end edge (4) of the at least one profile part (2) so as to form a holding plane (37).
