The force measurement, when joining components, is conducted by the motor current by default. This cost-effective approach permits a measurable accuracy of ca. 10 % of the force range.

The force measurement chain is used during highly precise joining tasks. The measuring chain extends the measurable accuracy to <1% of the force range.

The force measurement chain has the following characteristics:

Force transducers with compact construction in combination with industrial charge amplifier

Variants 1kN and 50 kN

Galvanic isolation

Reverse polarity protection

The distance measuring system enlarges the positioning accuracy of the servo press and makes an absolute position feedback over the entire route possible.

Thereby the distance measuring system is mounted decoupled from the remaining servo press. This permits to gather the smallest deformations of the workpiece (e.g. through spring back).

An accuracy of <0.002 mm can be reached with constant ambient conditions.

The active protective housing made of polycarbonate prevents the access to the danger zone and is equipped with a pneumatic opening and closing mechanism. The pressing process can only be started when the protective housing is completely closed.

A safety switch monitors the position of the protective housing. The safety switch meets the following requirements:

EN 60204-1 and IEC 60204-1

EN 60947-5-3

EN 62061: SIL CL 3

EN ISO 13849-1: PLe and Kat. 4

A further (h)aiLIGHT is the process visualization via energy efficient four-colour LED technology. Thanks to the process visualization, the user does not need any information of the user surface. The pressing process can be triggered via a remote release (e.g a foot switch).

A bright white light is available for the insertion of components. The joining process is depicted by the colours blue (pressing), green (component OK) and red (component defective).

aiSTART makes it possible to start the joining process in direct proximity of the workspace. This means: short distances and short loading times. The field effect sensors, which trigger the joining process, are positioned on the right and left side of the servo press. A quick touch is enough to start the joining process. The pressing process can be terminated at any time through an emergency stop button positioned at the front.

Furthermore, the pressing process may also be triggered via a remote release, e.g. a foot switch. Therefore, special interfaces are available.

The integrated compressed air or vacuum supply respectively can be used for different tasks directly at the tool. This is a huge advantage as no external supply lines are needed.

The vacuum is produced by an economical and quiet ejector. The vacuum generator has the following features:

High vacuum, high suction rate

Compact construction

Monitoring and visualisation of the negative pressure by vacuum sensor with LCD display

Integration in Fertigungslinien und Automatisierung

Rotary plates are necessary when efficient processes and high cycle times are at stake. Loading and pressing or joining may be conducted simultaneously. Rotary plates are produced exclusively according to customer specifications.

Working method

The user puts components into lower and upper stamp.

The user triggers the joining process by confirming the two-hand control. The turning unit swivels 180° to the pressing unit.

The pressing sleeve proceeds down and joins the components to a finished part. While the pressing unit joins the single parts, the tool can be loaded again.

The user triggers the joining process by confirming the two-hand control. The turning unit swivels back in the opposite direction. The production parts can be extracted and components inserted.

Depending on complexity and scope of the loading, it might be useful to conduct the loading externally of the press, in order to maintain a more comfortable working position. The thrust system – deliverable for aiPRESS servo presses of frame sizes aiPRESS6…30 – is the solution when ergonomic loading is at stake. The stable unit offers a great free space when loading the device and room to place small objects. The thrust system is locked pneumatically in extended and retracted position. After loading is completed, the component is pushed manually under the sleeve and pressed automatically.
