Definitions

  • the invention relates to a device for coring a cast workpiece, according to the preamble of claim 1.
  • the invention further relates to a method for coring a cast workpiece according to the preamble of claim 7.
  • the workpieces can be vibrated by strikes with a hammer and the core can be broken in this way.
  • a device or a method of the type mentioned at the outset are known, for example, from US Pat DE10136713 A1 , as well as the JP 2000079460 A known. From the DE 2658455 A1 and the DE 102011088958 A1 pressure medium-powered striking mechanisms have also become known.
  • a disadvantage of the known solutions is, above all, that if the energy transfer is not optimal, the core can be destroyed.
  • a defined stroke frequency is understood to mean a predetermined stroke frequency.
  • the beat frequency can be selected and adjusted as required.
  • the invention thus makes it possible to freely select the hammer's impact frequency in a wide band range and to implement an optimal and defined energy transfer to the core.
  • the device has at least one actuator for actuating the at least one actuating means.
  • the at least one actuator comprises at least one valve, which is arranged between at least one compressor and a piston / cylinder unit of the pneumatic hammer.
  • the at least one valve can alternately connect areas of the working cylinder to the compressor on different sides of an impact piston which acts on a hammer head and is displaceably mounted in a longitudinal direction of a working cylinder of the piston / cylinder unit his.
  • a high impact frequency with a low mechanical load on the valve can be achieved in that the at least one valve is designed as a rotary valve.
  • the device has at least one control connected to the at least one actuator for controlling an impact frequency of the at least one hammer and an input unit connected to the control for inputting Has values for the beat frequency.
  • the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names.
  • the position information selected in the description such as, for example, top, bottom, side, etc., are based on the figure described and illustrated immediately, and these position information are to be applied to the new position in the event of a change in position.
  • a device 1 for coring a cast workpiece has one or more hammers 2, 3, 4. Furthermore, the device 1 has one or more adjusting means 5, 6 for setting an impact frequency of the hammers 2, 3, 4.
  • the hammers 2, 3, 4 can be fixed in place and act, for example, on a clamping plate, not shown here, on which the workpiece is clamped, and set it in vibration. Alternatively, the hammers can also act directly on the workpiece.
  • the energy transmitted by the hammers 2, 3, 4 destroys a mold core of the workpiece that is usually made of sand.
  • An actuator 7 can be provided for actuating the actuators 5, 6.
  • the actuator can be, for example, an electromechanical actuator, in particular in the form of an electric motor with a controllable speed.
  • a pneumatic hammer 9 is used as hammer 2, 3, 4.
  • the actuator 5, 6 used to control the pneumatic hammer 9 can comprise a valve 8 which is connected between a valve Fig. 1 with the reference numeral 10 provided compressor and a piston / cylinder unit 11 of the pneumatic hammer 9 is arranged.
  • the valve 8 can be used to connect the areas of the working cylinder 13 to the compressor 10 alternately on different sides of an impact piston 14 acting on a hammer head 12 and displaceably mounted in the longitudinal direction of a working cylinder 13 of a piston / cylinder unit 11 of the pneumatic hammer 9.
  • the valve 8 is, as in the Figures 3 and 4 shown, particularly preferably around a rotary valve.
  • the rotary valve can have a valve body penetrated by channels, which is surrounded by a valve jacket. Openings 17, 18, 19, 20 are arranged in the valve jacket and can be made to coincide with the outputs of the channels of the valve body.
  • the valve body can sit on a shaft which is driven by the actuator 7.
  • the rotation of the valve body alternately connects the channels to the opening 19 of the valve 8 connected to the compressor 10 and to the openings 17 and 18 of the valve 8.
  • the opening 20 of the valve 8 serves for ventilation and can be connected to the environment.
  • the openings 17 and 18 of the valve 8 are connected to the two openings 21 and 22 of the piston / cylinder unit 11.
  • a single valve 8 can also be used to control them, the number of openings 17-20 in the valve jacket and the channels in the valve body and the length of the valve body having to be increased accordingly.
  • a single valve 8 it is also possible to arrange a plurality of individual valve bodies on the shaft driven by the actuator 7.
  • the channels assigned to the individual hammers 2, 3, 4 can be arranged in the valve body or the valve bodies in such a way that there is a fixed phase offset between the striking movements of the hammers 2, 3, 4 results. In this arrangement, the hammers 2, 3, 4 move at the same frequency and out of phase with one another with a fixed phase offset.
  • the device can have a control 15 connected to the actuator 5, 6, for example a suitably programmed processor, and an input unit 16 connected to the control, for example a keyboard, for entering values for the Have impact frequency.
  • a control 15 connected to the actuator 5, 6, for example a suitably programmed processor
  • an input unit 16 connected to the control, for example a keyboard, for entering values for the Have impact frequency.
  • a stroke frequency for each hammer is determined in step i) and a phase shift between stroke movements of the hammers in step ii).
  • the hammers 2, 3, 4 execute a striking movement with the defined stroke frequency and phase shift and shatter a core present in the workpiece.
  • the frequency can be selected by means of a corresponding input unit 16.
  • the phase offset can be determined by a corresponding arrangement of the valve bodies on the shaft connected to the actuator 7 or a corresponding arrangement of the channels.
  • a plurality of valves 8 can also be provided with a corresponding phase offset of the openings 17, 18, 19, 20.
