Windows fittings

This STIWA manufacturing line produces a corner drive. These are integrated into window frames and ensure that windows are moved to the desired position when the handle is actuated

The individual parts are fed as bulk material. The steel rails are fitted via a manual workstation and bent 90° using a fully automatic bending tool. Before installing the steel belt and bolts, the components are greased. The rod, screw guide and bolt are riveted fully automatically. The finished parts are dispensed to a buffer, removed by hand and packed.

KEY PROCESS BENDING

Depending on the type, the steel rails are variable in length and form the basic element of the corner drive. They are fully automatically bent 90°.

EXACT WORKING METHOD WHEN RIVETING

The bolts are riveted to the steel rail. They must be able to move after riveting and must meet the required tensile forces. Process monitoring is performed by measuring the force and monitoring the path.

CHECK OF FUNCTIONALITY

To ensure that the finished part is working correctly, the displacement force is checked via a force sensor.
