APPARATUS FOR SECURING TEST PLATE AT CHECKING INTENSITY OF SHOT-BLAST WORK HARDENING UPON WORKING SPRINGS

摘要

FIELD: apparatuses for mounting test plates for measuring intensity of shot blast work hardening. SUBSTANCE: test plate includes rigid base with flat smooth surface for placing test plate. At front side of test plate grid is mounted on base for simulating portions of turns of spring turned to shot blasting jet. Surface of base opposite relative to said flat and smooth surface is provided with rigidity ribs. EFFECT: possibility of accurately monitoring in time work harden level of springs, especially of inner fibers of spring turns. 2 dwg
