Device for synchronizing the lowering speeds f of the cutting torch and the semi-finished product to be cut in systems for continuous metal casting »

The invention relates to a "device for synchronization

the lowering speeds of the cutting torch and of the semi-finished product to be cut into pieces, eg «a block, in systems for continuous metal casting _D

To synchronize the movement of the cutting torch and the semi-finished product, devices are known that work with synchronous generators, which are connected to the drive shaft of the pull-out housing The cutting table is lowered at the same speed as the semi-finished product to be cut _o The cutting torch moves horizontally and parallel to a pool of the semi-finished product and cuts in a plane that is perpendicular to the semi-finished product axis.

With these devices, it is disadvantageous that there is a slip between the descending semi-finished product and the drive shafts of the pull-out _{housing 0} Furthermore, due to the wear and tear of the lowering rollers in the course of use, the synchronization of the movement of the cutting fish and the semi-finished product is subject to inaccuracies a cut that is no longer perpendicular to the descent axis »

The object of the invention is to eliminate these disadvantages and to achieve precise synchronization <,

The invention is based on a device for synchronizing the lowering speeds of the cutting torch and semi-finished product a system for continuous metal casting, comprising a carriage carrying the cutting torch, which is positioned horizontally on a table and is movable parallel to a surface of the semi-finished product, furthermore a device for bringing this table up to the Semi-finished product and an operating motor for the vertical movement of this Table. The device is characterized in that it has a button arranged parallel to the cutting torch, which, under the action of an elastic force, can make contact with the semi-finished product, and that this pushbutton moves one of the table axis held horizontal and perpendicular to the touch axis is pivotable, with an elastic part seeks to hold it perpendicular to the semi-finished product, and that a signal generator to regulate the Speed of the drive motor and a linkage for the transmission the vibrations of the button to the signal generator is provided.

Further details of the invention are based on the in the drawings illustrated embodiment explained.

Fig. 1 shows the synchronization device in elevation, wherein

the Easter is shown in the vertical section. Fig. 2 is a top plan view of the device.

The table 1 of the device can on guides, not shown Moved vertically · To get closer to the downward running Semi-finished product 2 or to remove it from the table 1 is horizontally displaceable. The horizontal shift is not done by well-known remedies shown »I.

Any means can be used to move the table 1 vertically e.g. chains 3, which run over the gears 4- and driven by the electric motor 5.

The cutting torch 6 is arranged on the carriage 7, which is used when cutting. which is moved in the direction of arrows 8.

The button, which is parallel to the cutting torch, has a housing 9 » in which the stylus 10 is mounted. The stylus 10 comes with its outwardly protruding tip in contact with the semi-finished product 2 «(

The housing 9 is pivotally held by the axis 11 in the Fork 12 attached to table 1 is mounted. The axis 11 runs horizontal and parallel to the direction of displacement 8 of the cutting torch carriage 7

The housing 9 is constantly looking for an elastic part, such as the spring 13 to hold parallel to the surface of the table 1, whereby the stylus 10 is also held perpendicular to the surface of the semi-finished product 2, which the cutting torch passes to cut.

The stylus 10 is normally elastic with its tip, pressed against the semi-finished product 2 · For this purpose, the one between the bottom 15 of the housing 9 and the head 16 of the Stylus 10 arranged spring

Furthermore, a signal generator 17 is provided «which via the from the Kuriw & arm 18 and the Treibliebe 1 19 existing linkage with the lower housing 9 is connected ».

When the button swivels around axis 11 » these are transmitted to the signal generator 17 »which is then via dlt electrical line 20 a control signal to the electric motor gives.

The crank arm 18 runs parallel to the housing 9 and, respectively, towards the goal its length is smaller than the distance between the axis of rotation of the button housing and the Brehaohse 21 of the drive lever 19 attached to the button housing Swivel movement of the housing 9 on the lever 18 enlarged, and you receives an amplified signal »

The device works as follows: While the semi-finished product 2 is being guided downwards by the lowering rollers, the table 1 is in the direction of the arrow 22 to the semifinished product 2 brought up until the cutting torch 6 is in the son's position In this position, the stylus 10 is pressed against the semi-finished product 2, and the spring 14 is under tension. The tensioning force of the spring 14 ensures that the stylus 10 is constantly on the semi-finished product 2 remains pressed down The table 1 is driven by the motor 5

lowered, the lowering speed being controlled by a synchronous generator (not shown) or solely by the button 9 can be regulated-. If a synchronous generator controlled by the pull-out housing of the semi-finished product is used, the device according to the invention only in action to the very exact To ensure synchronization of the lowering speed of the semi-finished product 2 and the table 1.

If in the course of the simultaneous downward movement of table 1 and Semi-finished product 2 If there are speed differences, the probe oscillates around its axis 11 · These oscillations are caused by the Lever 18 reinforced and solve depending on the deflection a more or less strong signal, which regulates the speed of the motor 5. The spring 13 acts constantly on the Eüokführung of the button in the horizontal position when correcting the speed of the motor 5 is executed.

During the downward movement of the semi-finished product, the cutting torch is exi Shifted horizontally on the table 1 and cuts the semi-finished product in an exactly «horizontal plane.

When the cut is finished, the table 1 is turned in the opposite direction of arrow 22 and then driven up to the starting position to take for the next cut.

Various embodiments are of course within the scope of the invention and modifications, especially of the individual parts, are possible} - e.g. the button or its parts 9 and 10 can also be made from other parts be built. It is advantageous in combination with the button Provide a cooling device operated with water, for example *
