Operators can select from predefined movement profiles or program them freely. This significantly reduces the threshold for fully exploiting the machine’s potential.
The ‘Smart Assist’ software guides the operator step-by-step through the set-up process, supported by short videos and text modules. The electronic assistant optimises the transfer and slide profiles to maximum output, depending on the clearance profiles – a complex process that used to take much time.
Thanks to the kinematics of the knuckle-joint drive, forming at the bottom dead centre is also slower, meaning that readjustment via the servo drive is not always necessary.
The process monitor integrated in the control unit offers extensive monitoring options. This ensures overload protection across the entire course of the press force profile and the entire movement profile; a minimum and maximum force can be defined for effective protection of the die. The response times of the electronically designed overload protection device are in the range of a few milliseconds, which is faster than with a hydraulic overload protection device. The press can be used again immediately after an overload has been detected.
While standard presses normally reduce the force in the event of an overload and drive the slide through the bottom dead centre to the upper reversing point, the MSP 400 has a ‘Smart Release’ function: here, the slide automatically runs back over a defined path after an overload has been detected, thus relieving the strain on the die and press.
The integration of additional sensors –for acceleration, oscillation or pressure – enables comprehensive condition monitoring of the system, which can be displayed in the control system’s visualisation. The basis for this is frequency spectra that provide information about possible wear in the gearing, bearing or motor. This prevents unplanned downtime and increases the productivity of the system. Furthermore, the process and condition data allow for complete quality control of the produced components.
Unlike a conventional press, the pressure points of the MSP 400 are not above the slide, but instead on the outside of the actual bed area. This allows the machine to absorb very high eccentric loads and means that around 25% more press force is available to both the infeed and discharge sides. This makes it possible to form even high-strength materials in the first die stage.
The geometric arrangement also gives the slide a high mechanical tilting rigidity. In addition, the deflection of the entire system is reduced, because the drive is located far to the outside of the crown. This makes it possible to achieve die-friendly forming and better component quality. The electronic coupling enables force-independent parallel control: in the event of an eccentric load, the drives are readjusted on one side without any loss of force, and the slide can thus be held parallel.
