Definitions

  • the invention relates to a device for controlling the advancing movement of a casting piston in a casting chamber of a cold chamber die casting machine by means of a control signal.
  • the invention is concerned with controlling the plunger feed motion during a time referred to herein as a chamber fill movement portion from a partial fill position of the casting plunger with a partially filled pouring chamber initial volume to a full fill position of the casting plunger with a filled casting chamber residual volume.
  • a melt to be cast typically a melt of a metal alloy of essentially aluminum and / or magnesium and / or zinc
  • a melt to be cast is known to be introduced into a horizontally arranged casting chamber and then conveyed into a casting mold with a casting piston driven hydraulically or in another way , This process is carried out cyclically for the purpose of the multiple production of identical products, with each casting cycle once melt is pressed into the mold.
  • almost exclusively cylindrical casting chambers with a circular cross-section are used.
  • the introduction of the melt into the casting chamber can take place in different ways under atmospheric pressure, superatmospheric or negative pressure, for example by filling via a filling opening of the casting chamber by means of a ladle or by suction by generating a negative pressure in the casting chamber.
  • the quantity of melt introduced into the casting chamber depends on the respective casting mold volume, ie the volume of the part to be cast, so that different fill levels in the casting chamber result depending on the casting and, after introduction of the melt, a certain overlying air volume remains in the horizontally arranged casting chamber cylinder, as long as the casting piston still in an initial position on one casting mold facing away, the rear side of the casting chamber cylinder is located behind a pouring chamber inlet.
  • air volume in the present case generally also includes the case that it is an upper partial volume of the casting chamber filled or evacuated with another gas.
  • the casting piston In a first phase of the casting-piston feed movement, the casting piston is advanced from its initial position, in which the casting chamber is partially filled, as far as the full filling position, in which the casting chamber volume successively reduced by the casting-piston advancing movement is just completely filled with the filled-in melt.
  • the press-fitting process which is of no further interest in the present case, by means of which the melt from the casting chamber is pressed into the casting mold via a casting-mold outlet facing a casting mold on a front side of the casting-chamber cylinder and the subsequent so-called casting run.
  • the invention is based on the technical problem of providing a device of the aforementioned type with which the advancing movement of the casting piston can be controlled specifically in the chamber filling movement section so that the amount of air / gas inclusions in the melt can be reduced or minimized, which typically leads to reduced porosity in the finished casting.
  • the invention solves this problem by providing a control device having the features of claim 1.
  • a respective course of an actuating signal is provided for different predetermined sets of values of a plurality of process parameters influencing the melt movement in the casting chamber during the chamber filling movement section, in the present case also referred to as parameters, with which it controls the advancing movement of the casting piston during of the chamber filling movement section from an initial Part filling position with partially filled G monhat initial volume up to the full filling position with filled Gellohunt residual volume controls.
  • the control waveforms provided are those which determine that one of them best fits the parameter value set in question.
  • “Best fitting” is to be understood here as meaning that the control signal curve assigned to the parameter value set in question leads to that course of the piston feed movement which, in the current situation described by the relevant parameter value set, better than all other contours of the piston feed motion considered the undesirable effects of wave flashover and Heilvolumenabschnü mentioned
  • the definition as "best-fitting” of course also takes into account the usual, relevant for the casting process criteria, such as the least possible time required for the casting cycle and thus for the piston feed movement.
  • the control device is accordingly set up to apply this best-fitting control signal curve as a function of values of the process parameters present at the beginning of a casting cycle.
  • the possible best-fitting control signal waveforms for different predetermined sets of values of the parameters considered are determined in advance, ie before the runtime of the casting process or casting cycle, and stored in the control device.
  • the control device selects for each casting cycle the best suited to the current parameter value set control waveform for controlling the G easilykolben- feed movement during the Kammer hypothaliana
  • This preliminary determination of different courses of the piston feed movement ie different courses of the relevant actuating signal, can be carried out empirically on the real object or preferably systematically and thus deterministically by means of appropriate computer simulations with suitable calculation models. The latter makes it possible to perform a comparatively large number of "trials" with varying values of the relevant process parameters.
  • the computation time is not limited to the typical casting cycle time, which allows the use of a relatively computationally intensive model
  • the simulated model system may in particular also be a simulated closed-loop system with a controller which attempts to correct computationally detected deviations from a desired melt flow characteristic with corresponding controller interventions the respective initial condition, as described by the currently used parameter value set, best fitting control signal waveform very accurate means of model-based control circuit simulation
  • a direct determination of the provided control signal curve during the runtime of the casting process can be provided.
  • the plurality of process parameters influencing the melt movement in the casting chamber during the chamber filling movement section comprises at least one parameter relating to the casting chamber geometry, at least one parameter relating to the fill quantity of melt material in the casting chamber, at least one parameter relating to the casting mold and / or at least one casting chamber and / or the melt temperature parameter. It turns out that, taking into account one or more of these parameters, very useful control signal curves for the piston can win winch movement, which avoid the undesirable effects regarding. Wave rollover or premature wave separation / wave reflection as far as possible. Depending on the application, one or more additional parameters can be taken into account.
  • each parameter is to be understood in such a way that, depending on the application, it may contain current values and / or values derived from one or more preceding casting cycles and / or values determined from such values, each of which is metrologically or computationally derived values can.
  • the plurality of process parameters more specifically comprises at least one casting chamber length parameter, at least one casting chamber height parameter, at least one casting chamber fill level parameter, at least one melt temperature parameter, at least one pouring chamber temperature parameter and / or at least one melt viscosity parameter and each Optionally, one or more additional parameters depending on the application.
  • the geometry parameters describe the spatial boundary conditions for the melt movement in the casting chamber
  • the temperature / viscosity parameters describe the flow behavior of the melt and possibly also any surface layer problems such as the so-called edge layer solidification of the melt on the casting chamber inner wall.
  • control signal waveforms provided are grouped into a plurality of types having a different number of successive stages, each stage representing an associated increase in melt height on the casting piston.
  • the grouping of all possible control signal waveforms in a discrete set of courses with different number of stages also has advantages in terms of storage space for storing previously determined, best-fitting control waveforms, with quick access to the stored data to select the best matching control waveform and with respect to the correspondingly stepped feed rate of the casting.
  • each level is set so that it specifies an initially accelerated casting piston movement followed by a casting piston movement with a speed profile, which is determined from a predetermined course of a height of the melt material on the casting piston.
  • this predetermined further course of melt height on the casting piston implies that the melt height, after having been relatively quickly raised to a higher level by the initial accelerated piston advance movement, is then substantially maintained at this new level or at least significantly more slowly increased further. It turns out that this connection of the piston feed movement to a specific time profile of the melt height on the casting piston can lead to very good, best-matching control signal curves for the piston feed movement. In addition, this offers the optional possibility of also intervening in the process of the piston feed movement by ongoing sensory detection of the melt height at the casting piston.
  • control signal waveforms provided are obtained by a model-based closed loop simulation system before or alternatively during a runtime of the casting piston feed movement, with the advantages indicated above.
  • a preliminary determination allows the use of larger computer capacities and thus more accurate calculation models.
  • An alternative determination directly at runtime allows the consideration of any current disturbances may still during the casting cycle.
  • the model-based simulation control loop system is integrated into the control device. It is thereby at the site of the control device, i. typically at the location of the associated casting machine, which is particularly favorable for the cases that a determination of the best matching control signal waveform is provided directly to the casting process or the casting machine user is to be able to determine even best-fitting control signal waveforms by model-based control loop simulation for the casting machine system in question.
