    An apparatus for controlling the treatment temperature of a workpiece processed in a current intensive glow discharge container, comprises a differentiator for deriving at its output a time derivative of the actual treatment temperature in the glow discharge container, a comparator for generating a control value corresponding to the difference between the time derivative and a preset desired value, and a current regulator controlled by the control value at the output of the comparator.

    专利说明:

    Optionally, the desired reference value of the treatment temperature can be set. The output of amplifier 3 is connected to the input of amplifier 2. As amplifier 3, it is advisable to use an optical amplifier (the same for amplifier 2), which, with large differences in the input section, will go to end mode, i.e., will work as a commarator while it is the one of the small values of the difference between the input and source 1, namely, when the temperature V approaches the given value of gyud, it produces a signal that tends to zero. When, the output voltage of amplifier 3 is zero. If, on the other hand, the temperature in time is not equal to the current temperature
    to zero then signal
    amplifier output is also zero.
    The device works as follows.
    The output of my amplifier 3 given by the value of L V is compared with the production of temdV
    neture time and time - the means of usidt
    The unit 2, the iric output signal is transmitted to the current control unit 4, which is specially designed as a proportional-and-integral (PI) controller with a long adjustment time period. The PI controller 4 increases, in the presence of the output signal of the amplifier 2, slowly and slowly, the current strength so that, due to incipient changes, the current in the chamber is not caused by the occurrence of arc discharges.
    To PI controller 4, it is advisable to input impulses for current flow when arcing arc discharges, and these pulses can come, ipprmsr, from a high-speed switch, which connects with doiol1Itelnym 5 of the Regulator 4. Such pulses can, for example, need to be applied. The integral value of the regulator is such that a reduction in the current increase or even a reduction thereof is obtained. In this way, feedback between the arcs of the arc discharge and the operating current for the glow discharge is created.
    The output of the PI controller 4 gives the desired value of the magnitude of the operating current /.
    FIG. 2 represents the course of aarastann temperature V depending on the time /. The solid curve represents the course of the process of launching a high-current glow discharge. The curve of nodiimags is continuous and automatically approaches the preset temperature of the Crcd processing.
    In the shaded area, amplification, or 3, acts as an amplifier, whereas below this shading area, it acts as a comparator, since, due to the large differences in the input voltage between V and Uzad, it operates in the saturation mode. Short breaks of the start-up process in glow mode as a result of the occurrence of arc discharges that are caused by interference. By virtue of the fast-acting switch, they do not entail a break in the curve, but lead to a corresponding regulation of temperature and temperature. With longer uninterrupted periods that may be caused by violations of a different nature, such as 1 imerime k), timeline, nodachn1 (coolingN1, its water, nairi.s.sr, during the time interval from /; to / 2, can cool down the processed Detail how it is presented and the product curve.
    The resumption of heating at time 2 and then, at that temperature, which is appropriate for the machining of the part, and it takes place at this time. I went up with a branch of this crank pattern then mostly mainly corresponding to it; it is often crooked, and the frequency of occurrence of arc digits is reduced to i.m.mum} due to signals emanating from the high-speed switch as a result of the reverse link. By such heathing of the heating process due to the operation of the quick-acting1, its switch remains insignificant, so that to carry out the process of heating up it is ensured that the time spent under the optimum condition of the parts is preserved.
