Description

Method and press for chamfering and deburring pressed panels Die on the slab pressing panels., especially stone slabs, point to the Edges: ridges that either point upwards when the panel is lying flat, if the plates are made with the punch entering the mold, or the are set on the side when pressing with an impacting punch. The two Types of ridges are shown in Figs. To avoid edge damage avoid, these burrs must be removed. Often times, even attaching one Bevel required.

In order to be able to do this automatically, there are usually special ones Deburring devices or special deburring machines are used. From the form ejected and 'finished at table height of the plates: press brought Plates. are pushed off to the side :. So with this movement not yet Deburred edges are not damaged, they are placed between the round plates Sticks or whole rakes or lattices with the. Panels together. be moved. and: whose constant circulation makes it difficult.

After the bevels are made, the panels must be: two parallel to each other lying sides are attached to be rotated by 90 ° so that the not yet broken Edges get in front of the tools. It is necessary to separate the plates. the Panels must be raised apart by rapid transport. This and the device for the plates require additional, space-consuming and failure-prone Special devices only for trimming-n and. From: chamfer the panels.

To the panning. the freshly pressed plates. has to avoid the deburring tools at right angles to each other at different heights arranged and this corresponding plates. from the conveyor belt to the area of action of the one, ajus emery strips, existing tool and after processing the first two. Chamfer further up to the right-angled emery strips upscale. After all bevels have been made, the plate is put back on the. Sponsor discontinued.

Separation of the plates is also necessary here. The chamfer in: two altitudes. requires further additional: time. Besides the deburring und Abgratungswerkz.eugen is a special two-stage lifting device necessary.

A similar device has also been added to the presses themselves. It also works with a special lifting device that lifts the plates. brings to the tools, and requires additional slide frame to control the Work movements when deburring and chamfering.

After all, it is known from turret presses for ridge tiles the crankshaft, which carries a mold half, via Noeken., shafts, toothed segments, Lever and link a wire to cut the burr on the. Briquettes in. to move back and forth in one direction. Apart from the fact that there are no wires to the Chamfering of freshly pressed panels can only be done with this device be chamfered in one direction. The engine would be strong with a plate press exposed to pollution and damage, there would also be accessibility to the press, make it difficult.

The invention is based on the object of freshly pressed panels to be trimmed and chamfered on four edges at right angles to each other. the Solution to this problem is based on the thought that is required in the press anyway. Movements for deburring and chamfering, exploiting the panels.

Any deburring can be done during the movement or reverse movement of a of the press part moved in the corresponding direction: are made. This will initially saved time. The demolition can be done in, the time, in which anyway: the press parts are moved forwards or backwards. Furthermore, can also be a special Trimming device with its own drive can be saved, since the trimming device can be designed as an appendage to existing Prussian parts. For example the trimming device can be switched on, the horizontally moving pressure piece of a press Attach with the press ram penetrating into the molds from below.

If the pressure piece goes back to its starting position, it pulls the From: grariverkzeuge after you. So E are neither a. special drive still special guideways required for the trimming device. In a similar way the movement of the filling device, the deburring device can be used for the trimming equipment and other press parts are used. Preferably a Embodiment used in which the carrier for the trimming tools on the upper punch while the trimming tools working at right angles to it get in the way of the plates leaving the machine are arranged so that the pusher for the plates at the same time brings about the movement required for trimming.

The tools can be designed in a known manner and on sliders be adjustable. Cleaning rollers and other can be attached to the deburring Facilities. for surface treatment of the panels. Such facilities can also be assigned or connected to each individual group of trimming tools will..

In the drawing is a. Illustrated embodiment of the invention.

Fig. 3 shows the connection between the trimming tool and the upper punch again; Fig. 4 is a top view and Fig. 5 is a front view: Fig.6 shows a pictorial view of the facility.

The upper punch 1 is in a known manner in a slide guide 2 of the press 3 horizontally movable and forms the abutment when pressing the of down in the mold penetrating punch 4. There will be. four plates 5 each pressed. After pressing, the plates are in a known manner upwards. pushed out., so that their lower edge is level with the press table 6. The upper stamp is withdrawn to the right in Figure 6. There are 10 slide rails with side arms on it 11 attached on which. the sliders 12 moved laterally and adjusted can be. These sliders carry the trimming tools at the lower end, e.g. B. Trimming rollers 14.

When the punch 1 moves to the right, it accepts this. him attached trimming tools 14 with, and those lying in this direction of movement Burrs are eliminated.

Then, with the help of the filling slide 15 (Fig.4), the finished and already in: one direction trimmed plates 5 in the transverse direction Direction pushed together and then out of the machine in the direction of the arrow 17 moved out. You get between. the guide strips 18 and then on the trimming tools 19, which at. a fixed slide rail 11 with the sliding pieces 12 are attached. Of the tools 19, those that have not yet been processed are also not yet processed Trimmed the edges of the panels. Then get there. the panels in, a cleaning facility 20 known design and abandoned. finally at 21 the press.

From the Abh. 6 it can be seen that the trimming device opposite known. 1Vlaschinen is very simplified, it only needs the additional attachment of parts 10 to 14 and the die 1 and the corresponding one, which is present anyway Arrangement of the same parts in front of the cleaning device 20 in order to achieve that the Leave the press plates already trimmed or provided with bevels. The few additional ones. Parts on the press replace all of the usual ones. Abgra.teinrichtuiigeii. Basically, three groups of advantages are achieved: One is the the entire. and the sources of interference are reduced to a minimum value; secondly, requires the trimming does not require additional service and attention, since. the press operator: can also finitely monitor cia, s trimming, because the trimming devices are completely lie in his field of vision; third, there is practically no additional space required for the trimming device, so the space in the press is largely free and not messed up: the press is easily accessible and light from all sides to monitor.

The invention is useful both in the manufacture of individual panels can also be used in the series production of, for example, four or nine plates.
