Hardness test benches
The hardness testing systems are automated and/or integrated into the production process, with and without component feed.
Hardness tests on components with complicated geometries or tests in the running production can sometimes not be covered with standard hardness testers. In these cases the company Hegewald & Peschke GmbH offers you the complete engineering know-how for the realization of the testing task. Our already produced hardness testing systems include: Hardness testing stations for crankshafts, automatic rim hardness testing systems, hot hardness testing systems, circular blank testing systems and portal hardness testing systems.
The following specifications are fulfilled by the hardness testing equipment:
Test sequence/technical description:
The crankshaft is brought with a crane to the hardness testing equipment and clamped firm between points on the XY cross table. For this the cross table is driven into the preparation position (approx. 500 mm in operator direction, freely accessible from above). The cross table is manually in x and y-direction adjustable and the test specimen can be turned around its longitudinal axis. The cross table is stored in a high-quality ball rotating rail guidance. In x-direction a rest rail is intended, which makes faster positioning possible. The rail is replaceable for different test specimens.
If a test position is reached in XY direction, the prism tables support is driven with a Joystick by electric motors from down against the test specimen, with which this is centered and - on use of the anti-twist plate - is strutted.
The hardness measuring head is by electric motors in z-direction displaceable. By Joystick it is moved downward, where it stops with reaching the test before strength. The loading and relieving with test load takes place manually at a lever.
For the security of the operator the movement by electric motors is possible only in two-hand control.
