    Control of the working frequency of a striking mechanism
    The invention relates to a control of a middle of a pressure medium operable striking mechanism with a center! for reversing the axial 5 Druckbeaufschiagung the percussion piston and the return of the medium.
    Furthermore, the invention relates to a striking mechanism for a device for opening and optionally closing a tap hole in the wall of a metallurgical vessel. 10
    Hammer mechanisms for an axially replaceable in both directions hammer device are known and are state of the art.
    Advantageously, these striking mechanisms are used in means for opening and / or closing a tapping opening in a metallurgical vessel.
    For example, EP 0930476 A discloses a striking mechanism with a cattail in a hammer device for the above field of use. In this case, the tool is applied during use in propulsion and also in retreat essentially with the same 20 impact energy and impact frequency.
    In order to change the impact frequency and the impact force of the piston of a striking mechanism in both directions, it has been proposed according to A11397 / 2011, in the tubular piston a control recess and axially offset in Schlagwerksgehäuse 25 at least two Steuemuten for switching the Druckbeaufschiagung the respective Rohrkolbendruckflächen provide and by a control means Alternatively, to activate the Umsteuerungsnuten, It is achieved that the tubular piston performs a different displacement or acceleration in both directions of impact depending on the activation of one of the staggered Umrichtungsnute in Axrichtung.
    Particular requirements for the propulsion and retraction conditions for tools, in particular of facilities in the metallurgical industry, currently make demands on a controllability of the 2/11 on a striking mechanism
    piston movement
    The invention is therefore based on the task to improve the controllability of percussion and to create a control device to 5, by means of which the energy and the frequency of the moving percussion piston are adjustable within wide limits.
    This objective is achieved by controlling a percussion mechanism which can be operated by means of a pressure medium of the type mentioned above, in that at least one of the reversing control means for the medium switchable by the percussion piston has at least one shieldable means for flow control.
    The advantages achieved with the invention are essentially to be seen in the fact that the backflow of the medium moving the piston takes place according to volume control after a changeover. By means of, for example, different flow openings of a switching means, which can alternatively be activated in the return line, the backflow of the medium can be changed for reversal, so that the time until the following pressurization of the impact kibble is variable. In this way, the impact force and in particular the beat frequency can be controlled zo, wherein a delayed reversal affects the impact energy.
    A change in the flow rate per unit time in the return line or a Durchfiussregeiung in this can be achieved in a simple manner, for example, by a switchable means, with different cross-sections Engsteilen in 25 flow channel.
    A flow rate control or a pressure over time takes place in the return line of the expanded medium, which changes the frequency and consequently the energy or the intensity of the strokes of the piston. For an advantageous universal control behavior in both directions of impact of the striking mechanism both of the reversal as a return line for the medium of the percussion piston schaitbare channels switchable means for flow control 3/11 30 2 have.
    The switchable means can thus control the impact mechanism in each working direction and optimally adjust the tooling of a device optimally.
    It may be advantageous if the switchable means for flow control for the medium are separated from each other adjustable. A control device as described above can optimally meet substantially all requirements imposed on a percussion mechanism in a harsh application.
    With particular advantage, a control according to the invention of the type described is suitable for a device for opening and / or closing a tapping opening of a metallurgical vessel.
    The control offers the possibility, with regard to the brittle and fracture-endangered refractory lining masses of a metallurgical vessel, to create optimal conditions for opening a tapping in a melting vessel.
    As a result, the control of an impact mechanism operable by means of a pressure medium is to be conveyed to two graphic representations, each of which represents only one embodiment of the invention.
    Show it:
    1 shows a control device with a flow control positioned in a return line 3o FIG. 2 a universally applicable control device for the movement of a sliding latch
    For easier allocation of parts and components in the illustrations of 4/11 3
    Control devices according to the invention may serve the following reference signs.
    List of Reference Numerals: S Control device 1 Housing 11, 11 ', 13 Cover 12, 12' Switching insert 2 Reversing section 21 Supply chamber for pressure medium 22 Achievable channel in housing 23 Switchable channel in housing 3, 3 'Switching means 31, 31' Means for flow control 32, 32 ' Flow control device 33,33 'Pressure spring 34.34' Control fluid supply 35,35 'Pressure surface 4 Fluid discharge 20
    1 shows a control device S with a housing 1, which has a cover 13, 11 on both sides in the axial direction, wherein a cover 13 with a projecting insert serves as a medium discharge 4. 25 an opposing cover 11 acts as Befestigungsmittei for a switching insert 12 with a control means supply 34 in the switching insert 12 axially slidably within limits a tubular Schaitmittel 3 is arranged, which on the one hand by a spring 33 which is supported on the cover 11, axially with a compressive force is charged. On the other hand, via the control means supply 34 39 pressure medium, which is effective on a directed against the spring force pressure surface on the switching means 3, are eingieitet and move it against the spring force. In this way, the switching means 3, which extends into the cavity of the Umsteuerteiles 2, are positioned. 5/11
    In the housing 1, the reversing part 2 is arranged axially movable within limits, wherein on the use of the cover 13 and the switching insert 12 radial stop surfaces are used for the respective positioning of the switching part 2. 5 The inner surface in the housing 1 and the outer surface of Umsteuerteii 2 have recesses, which open depending on the axial position of the Umsteuerteiles 2 ways for a flow of the pressure medium or a return flow of the medium to or from percussion. In the illustration according to Fiq. 1 is the Umsteuerteil 2 in the attack on the
    Cover 13.
    A supply chamber 21 for the pressure medium is connected to a channel 22, so that this pressure medium acts on one side of a piston in the striking mechanism. 15
    From the opposite side of the piston is a return of the medium through a channel 23 in the housing 1 and this medium is passed through a hole in the switching part 2 (not shown) in an outer space of the switching means 3 and centrally by a means 31 in this flow control thereafter spent to 20 medium output.
    The means 31 for flow control controls the return flow of the medium or the time until softer the pressure in the return channel 23 is lowered so that a shift of the Umsteuerteiles 2 by the pressure medium to 25 the radial pressure surface of the part against the switch insert 12 takes place, thereby the return flow path is switched off and the channel 23 for the conduction of the pressure medium to Schiagkolben umunktionierf is.
    At the same time, the displacement of Umsteuerteiies 2 causes a 30 interruption of the supply of pressure medium and a circuit of the channel 22 ais return line for the medium, which is passed through the recess and through a bean in Umsteuerteii 2 to Medienaustrag 4. 6/11
    Now, if the switching means 3 is inserted by activation of the spring 33 and a pressure reduction of the control means axially to the switching means 2 in this, acts on the surface recess on the switching means 3 and the means 32 for Durchflußrefrungung in the medium discharge a 5 modified backwater or a different Outflow of the medium in the unit time, whereby the timing of the reversal of the pressure medium is changed to the respective pressure surfaces of the piston.
    Because now in a subsequent reversal, the return of the medium io from the channel 22 through a bore 30 in the reversing part 2 to the media discharge 4 out unaffected takes place in one direction, the energy of the percussion equal or not regulated.
    In Fig. 2 a universally applicable control device for a movement i5 a shock is shown koibens.
    In essence, this universally applicable control device is constructed in mirror image and has in comparison with FIG. 1 centric-symmetrically identical Sehaiteinsätze 12,12 'with switching means 3, 3' 2o on.
    From the description of Fig. 1, a person skilled in the operation of a universal control device according to Fla. Derive 2. The advantage of the control device shown in FIG. 2 is a universally controllable feeding of a piston in a percussion mechanism and thus a far-reaching adjustment of the intensity and the frequency of percussion devices of a hammer device which may act in both axial directions. 7/11 6 30
