Unit for automatic occurring notched impact bending tests and method for carrying out this test so that large series of tests can be carried out per day with tempering and notch miller also measuring unit

摘要

The series of tests can be carried out in an automatic operating cycle after pretrial with suitable samples selected from a magazine of pendulum hammers (12) and its physical data for determining friction is established with a no-load impact test, and the result is deposited in a data processing system for further use. The automatic system with its computer assisted evaluation unit also controls the operating cycle facilitating the resting of series of large number of samples. A motor driven follower plate with a rubberised follower (14) seats on the shaft of the pendulum impact mechanism (1, fig.1a), from which the pendulum hammer is swung back from the raised position and completely lifts or turns in an end position.
