Title:
HARDNESS METER
Document Type and Number:
Japanese Patent JP3312495
Kind Code:
B2
Abstract:
PURPOSE: To provide a hardness meter which can move a warped test without contacting a spot anvil.
CONSTITUTION: A spot anvil 5 is provided at a placement stand 4 for placing a test piece while the placement stand 4 is laid out opposite to an indenter 6. The hardness meter is provided with an upper press member 31 which is driven by a cylinder device 32 and holds and clamps the test piece to the placement stand 4 from an upper part and a lower press member 33 which is driven by a cylinder device 34 and clamps the test piece from a lower part between itself and the upper press member 31. The thrust of the cylinder device 32 is reduced as compared with that of the cylinder device 34. Therefore, while the test piece is clamped by the upper press member 31 against the placement stand 4, the lower press member 33 is driven upward by the cylinder device 34 and the test piece is clamped by the upper/lower press members 32 and 33, thus retreating the test piece upward from the spot anvil.
