Rockwell hardness tester for large components

Product catalog summary

Overview: The document provides detailed information about the portal hardness testing device designed by Hegewald & Peschke for Rockwell hardness testing of large and heavy elements. The device is specifically tailored for the Rockwell method HRC according to DIN EN ISO 6508 standards.

Design and Construction: The testing portal features a robust frame built as a portal with a clear width of 1360mm and a height of 1000mm above the ball caster table. It accommodates components up to 1200mm in width and 900mm in height, with a minimum specimen height of 100mm. The device includes a manually positioned search unit and a hand lever for executing measurements. The portal is mounted on a guiding system, and the lower frame serves as a ball caster table.

Specifications: The Rockwell probe type AT130 is used, with manual bracing to enhance stability. The longitudinal adjustment is manual, and the vertically adjustable hardness probe is mounted on a heavy-duty carrier. The electrical supply is delivered via an energy chain, with no additional media required. The overall size is approximately 2500mm x 2500mm.

Ball Caster Table: The table dimensions are 1340x1360x500mm, with ball casters of Ø 25mm, a division of 130x130, and a load capacity of 100kg per ball. The maximum specimen weight is 900kg. The ball insertions are compressed and singly exchangeable, with a coated frame.

Test Procedure: The device uses a penetration depth measurement with a proof ferrule, employing a push sleeve principle to resist deflection and overhanging. The test load is chosen manually, and the functional principle involves applying test preload and overall load with a single lever pressure. The device features a digital display for hardness values and measurand output, with an RS 232 interface, scale choice, tolerances, and calibration options.

Scales and Accessories: The standard scale is the Rockwell scale HRC, with optional scales including Rockwell HRA, HRB, Brinell HBW for ferrous and non-ferrous metals, and Vickers HVT for ferrous metals. Standard accessories include a probe with a standard scale, various penetrators, a hardness comparison plate, bearing surfaces, a standard proof ferrule, and an instruction manual.

Design of the construction and test procedure The testing portal is used for the hardness testing based on the Rockwell method HRC according to DIN EN ISO 6508 at large and heavy elements. The machine frame is built as a portal with a clear width of 1360mm and a clear height of 1000mm above the ball caster table, so that components up to a maximum width of about 1200mm and a maximum height of about 900mm can be crossed and tested. The minimal height of the specimen is 100mm. The preparation of the testing point has to be carried out beforehand. The search unit is positioned manually at the desired...
