Definitions

the invention relates to a control system for the clutch and / or brake on the main drive shaft of a press, in which a clutch cylinder or a brake cylinder counteracting the braking force is reached by means of at least one valve until the desired speed (operating speed or standstill) is reached , which can be controlled before reaching the desired speed (operating speed or standstill), can be acted upon with at least two different pressures, one of which is at least approximately the maximum clutch pressure or the at least approximately pressure relief and the other a partial pressure which is above the response pressure of the clutch or below the counter pressure canceling the response pressure of the brake.
the solution to this problem according to the invention is based on the principle of a temporary adjustment of the partial pressure during the period comprising reaching the desired speed (operating speed or standstill).
the solution of the above object is that the pressure during coupling or braking after reaching an intermediate pressure, which in the case of the coupling between a value significantly (by at least 40%) above the partial pressure and the maximum Clutch pressure and in the case of the brake between a value significantly (at least 40%) below the partial pressure and full pressure relief, before reaching the target speed (operating speed or standstill) on the partial pressure for at least until the target speed is reached (operating speed or standstill) sufficient period can be switched.
the clutch or brake responds quickly at the start of the process and a high clutch or braking torque builds up quickly.
the subsequent switch to the lower (clutch) or higher (brake) partial pressure leads to a decrease in the clutch or braking torque until the desired speed is reached (operating speed or standstill), which results in the desired softer transition.
at least approximately the maximum clutch pressure or the at least approximately pressure relief is to be set again so that the full clutch torque is available for the operation of the press or the full braking torque for holding the ram and its drive elements.
the switching between the different pressures is not without inertia, that is, by leaps and bounds. It may also be expedient to carry out the switchovers in stages, for example from the intermediate pressure to the partial pressure.
the controller expediently contains a time-control device which responds to speed, angle, time or pressure and during which the partial pressure is effective.
the intervention of the time control device and its switch-on time are to be dimensioned such that the desired speed (operating speed or standstill) is reached while the partial pressure is effective.
the switchovers between the different pressures can be carried out with smooth transitions, so that the vibrations that occur are kept to a minimum.
the control according to the invention can also be used with the same effects in a press, on the main drive shaft of a known clutch-brake combination (DE-PS 12 07 725) is provided, in which a cylinder at the same time the clutch and the Brake cylinder forms, in which a piston which alternately influences the clutch and the brake is guided.
the response pressure is represented by the horizontal line pA.
an intermediate pressure pZ is first controlled, whereby a quicker Rise of the clutch or braking torque M results in a relatively high value.
the subsequent changeover to a partial pressure pT leads to a drop in the clutch or braking torque M to a lower value, which is maintained until the desired speed n (operating speed or standstill) is reached, which results in the desired effect of a softer transition results in the target speed n (operating speed or standstill).
the pressure p is switched to the maximum clutch pressure pM or pressure relief pO.
a pressure medium source consisting of a pressure medium delivery 1 and a pressure medium accumulator 2 is provided, which is connected via a pressure reducing valve 3 and a (conventional) press safety valve 4 to a cylinder in which a piston is guided.
the pressure reducing valve 3 is under the influence of a time control device or a program control (not shown in the drawing).
a clutch piston 6 is guided in the clutch cylinder 5, on which a compression spring 7 acts in the opening direction of the clutch and via a piston rod 8 affects the clutch in the closing direction.
a brake piston 10 is guided in the brake cylinder 9, on which a compression spring 11 acts in the closing direction of the brake and which influences the brake in the opening direction via a piston rod 12.
a clutch and brake piston 14 is guided in the cylinder 13, which forms the clutch and the brake cylinder, on which a compression spring 15 acts in the opening direction of the clutch and at the same time in the closing direction of the brake and which is provided on both sides with a piston rod.
the piston rod 16 on the cylinder space side influences the brake in the opening direction
the spring side piston rod 17 influences the clutch in the closing direction.
