"Device for processing the weld seams Plastic profiles, especially on plastic windows "

The innovation relates to a device for processing the weld seams on welded seams Plastic profiles, in particular plastic star.

In the case of two or more sash windows, V-cuts are sawn into the frame and the one to be connected to it The setting post is sharpened according to the V-cut. The Frame (fighter) connected to the setting post. The resulting V-weld seam must be reworked.

The task of the innovation is to provide a device that is simply constructed, easy to use and safe tu create, with which the weld seams in plastic profiles, especially plastic star, in a simple, Can be processed more efficiently and according to the desired visible edge requirements.

According to the latest innovation, this task will be solved » that on one the plastic profiles (window frame in the Sohweißbereieh) position-fixed holding base plate in guides running at an angle to one another (towards one another) two knives alternately by means of a lever linkage guided displaceably in the machining movement are stored.

They are preferably supported by the welded one Plastic p <trfile forming a unit on support pieces the base plate and are on the one hand by stub projections in the plate plane against displacement and on the other hand by a clamping lock on the base plate locked.

The two knives are turned against each other by a control plate operated by a hand lever that can be pushed back and forth moved »with the exception of guide slots in the base plate and in the control plate are »in which each knife engages with a guide and according to the lever movement towards and across the weld seam or from the weld seam is moved away.

Advantageous further developments of the subject of the innovation can be found in the other subclaims. Of the The subject of innovation does not only extend to the Features of the individual claims, but also on their combination.

With the device according to the innovation is in a simple, Lighter in terms of handling and safer in terms of design White a processing (Fesraiverglsiahmlichen and working off) the visual welding seam (s) on the most diverse, Plastic profiles welded together, especially on plastic star, namely welded setipfoets and fighters «possible«

With this device, manual actuation (moving a hand lever to the right and left) positively controls two knives on guideways, which are alternately pushed into the area of the weld seam and carry out the weld seam processing and is then pushed towards the weld seam for processing »whereby the previously effective knife is moved from the weld seam at the same time»

The knives have a freely selectable cutting edge (cutting projection or cutting rod) »through either a visible groove in the weld seam after it has been worked off or a weld bead can be worked out can. The knives are shifted in a straight line in one plane and work along the entire length of the weld seam uniform machining.

The entire device consists of a few, simple and inexpensive to manufacture individual parts and has • a high practical value.

An exemplary embodiment according to the innovation is explained in more detail below with the aid of the accompanying drawings. Show:

and 'H cross-sections through machining knives.

The device according to the innovation for processing the weld seams 3 on plastic picks 1, 2 that are welded to one another, in particular the V-shaped weld 3 between transom 1 and setting post 2 in the case of plastic star, has a base plate U on which the welded plastic profile 1, 2 can be fixed in position. For this purpose, the base plate 4 has several, for example six, support parts S ″, which are preferably formed by screws which are continuously adjustable in slots 6 of the base plate H , which in pairs lie on opposite sides of the profiles 1, 2 and thus change the position (slip) of the to prevent a T-shaped welded profile 1, 2 in the machining area (in the area of the base plate U). Furthermore, the position fixation of the T-profile 1, 2 is duroh

a tension lock 7 causes which on the base plate 4 is arranged and acts in the direction of the base plate plane on the T-profile 1, 2, so that the support parts 5, which ab.tehen from the base plate 4, result in a T-profile locking in all lateral directions and the clamping lock 7, the T-profile 1, 2 on the base plate 4 holds. The clamping lock 7 is involved in this process a pressure part 7a clamping onto the profiles 1, 2 in the \ ren T-joint area.

On the base plate 4 there are two guides 8 which are displaceably guided in a V-shape relative to one another 9 stored, which by means of a manually operable lever linkage 10, 11 alternately in the processing movement be moved. The sliding movement of the knife 9 takes place against each other, so that a knife performs the machining and the other knife 9 has been moved out of the area of the weld 3.

The lever linkage is composed, for example, of a handle 10 and a control plate connected to it

11 together, this control plate 11 being supported on the base plate 4 so as to be displaceably guided transversely to the longitudinal direction of the setting post 2. Each knife 9 summarizes with a Führungsansatζ 12 in a guide formed by a slot in the base plate 4? The two slots θ run at an angle, preferably at right angles, to one another. Further summarizes each knife 9 with the Führungsansatζ 12 in a control slot 13 of the control plate 11, where this control slot 13 is angled to the guide slot 8, preferably parallel to the longitudinal direction doe set upright 2, geriahtet ·

Through these two slots 8 »13, the knife 9 is pushed through the handle when the control plate 11 is moved 10 inevitably shifted, namely the «ine knife 9 in the direction of the weld seam 3 and the other knife 9 away from the weld 3. The peg-shaped guide attachment 12 slides in the base plate guide slot 8 back and forth and is through the control Λ slot 13 of the control plate 11 in its direction of movement determined, which in turn is dependent on the direction of displacement of the control plate 11.

The two knives 9 are used to process the weld seam 3 and either bring about uniformity in terms of shape. gene of the weld 3 or a processing and creation of a visible joint.

The knife 9 according to FIG. 3 creates a visible joint in the area of the weld seam 3 »in that this knife 9 ri.it a Cutting projection 9a is provided, which the weld 3 processed and at the same time a recessed chins () in the profiles 1, 2 forms.

The knife 9 according to FIG. 4 has a cutting groove 9b, with which the protruding weld 3 is smoothed and evened out, so that the then still protruding weld 3 results in a visible bead.

The welded T-profile 1, 2 is supported on support pieces 14 fastened to the base plate U, through which the T-profile 1, 2 lies at a distance above the base plate 4 and because the knife 9 can be moved between the base plate 4 and T-profile 1, 2. Process the knives 9

thus always the welded side of the profiles 1, 2 facing the base plate 4 and after this Machining, the T-profile 1, 2 is rotated 180 °, so that then the side that was previously on top the base plate 4 facing i & t and also processed can be. By moving the Reheis - '10 to the left or right, a knife 9 moves over

the one weld 3 and machined this and when moving the lever 10 in the opposite Direction then moves the previously effective knife 9 out of the weld area and the other Knife 9 carries out the weld seam processing. Thus, by moving the Lever 10 machined the V_-shaped running weld 3 on one profile side and by loosening the Tension lock 7, turning the T-profile 1, 2 and fixing the tension lock 7 can then the other side of the profile \ can be edited in the same way.

The amount of displacement of the knives 9 is continuously adjustable, which can be achieved by adjusting screws or the like, which can interact with the knives 9 and / or the control plate 11. These adjusting screws or stop-like built-up stops, which are not shown, are provided on the base plate 4.
