"Flame cutting device"

The invention relates to a flame cutting device with a flame table on which the objects to be cut are placed are placed on a torch arm, on which one or more cutting torches are guided over the firing table and a collecting device arranged under the firing table for the waste generated during the firing process Dust.

With flame cutting devices, especially oxy-fuel Flame cutting devices, results from mass operation the difficulty of dust suppression or proper dust collection during the burning process. So far one has

this problem in cumbersome: · Much. ο · ί solved, that one sets up catch pans made of folded sheet metal under the firing table, which are covered with water and which extend over the entire extent of the firing table. The dust produced during cutting, especially iron dust, could then be bound in these water-filled tubs. Inco, especially with larger firing tables, there was no cumbersome cleaning of these tubs, which moreover could only be carried out after the end of operation. In addition, the boxes are the sump trays considerably.

It was also known to fill the tubs with sand to make cleaning easier. Also tried to solve the problem by using a traveling grate has built individual tubs, with the tubs filled with water were filled and were tipped out at the end of the circulating traveling grate. This solution is also extremely complex and a relatively large amount of water is required because the water is due to the continuous running of the traveling grate is poured out of the tubs again and again.

The control device can have a monitoring device which monitors the movement of the torch arm and a drive motor for moving the drip pan keeps in operation as long as the burner arm moves, The monitoring device can have switches for this purpose, which monitor the movement of the torch arm. Of course, light barriers can also be used for monitoring corresponding ^ electronic signal generator u, like. to use come.

To monitor the movement of the torch arm, switches can be slidable together with the torch arm, which are closed while the burner arm is moving and are open when the burner is at a standstill. at When the switch is closed, the drive motor is driven and switched off when the switch is open, so that the drive motor, which at the same time also moves the drip pan, is then stopped when the burner arm stops moving.

To enable the switch to be moved, you can this au! an endless chain that runs parallel to the

Direction of displacement of the Breuner arm extends, arranged be. Advantageously, two switches are used here, between which a switch actuation element which is connected to the torch arm protrudes. The endless chain on which the switches sit can are advantageously driven by the drive motor, which simultaneously moves the drip pan serves. Furthermore, the distance between the two switches on the endless chain can be such that at small deflections of the; Torch poor, in particular In the case of curved cuts in which the torches only perform the smallest movements, the motor is not switched on, so that the drip pan is not moved either. With these small torch movements namely ensure that due to the width of the drip pan the resulting dust is still collected. With larger displacements of the burner arm in the longitudinal direction of the The burner table touches the contact rod protruding between the switches one of the two switches, which then switch on the drive motor so that the drip tray moves the burner arm with it and stops at the point at which the torch arm or cutting torches are stopped. Included several burners, these burners are located on the table

wide, it is sufficient to provide a relatively narrow drip pan with such a width that catches the dust that arises at each burner point. One comes therefore in contrast to the state of the Technique with a drip pan, the width of which is significantly smaller than the extension of the known Collecting tray * !. The width of the collecting trough in the invention is only a small fraction of the longitudinal extent of the burner table. In contrast to the prior art, this tub, which is only slightly Has dimensions and which can therefore be easily transported to graze, easily emptied, so that cleaning does not cause any difficulties.

In the accompanying figure, a preferred embodiment of the invention is shown. Using this figure 00II the invention will be explained in more detail.

The flame cutting device shown in the figure has a racing inch 1, over which a torch arm 2 is guided. ^{Burners 5 and (} > are arranged on the burner arm 2. There can also be more burners on the burner arm readers. In addition to the burner ticch 1

The mode of operation of the torch cutting device shown is the following:

With a greater deflection of the; Burner arm 2, in particular when changing the burners 3 and 6 to a different burning point, the contact rod 17 touches one of the two switches 3 or k, whereby the drive motor 7 is switched on. As a result, when the burner arm 2 is displaced, the drip pan 11 is also displaced. Here, the driving force of the motor 7 via the front

If the movement of the torch arm 2 is stopped, the contact rod 1 enters the space between the two Switches} and ^, whereby the motor is switched off, see above The movement of the drip pan 11 is also terminated. This ensures that the drip pan 11, which is only dimensioned so wide that the dust accumulating at the respective burner points is caught can always be arranged under these burner points during operation. You need therefore only a small width for the collecting trough 11 for this purpose.
