Features: The surface hardness of sand mould is scored as: B, C, three models, of which: C Model: apply to high pressure molding sand surface hardness test. Among them, the most commonly used model is B, and the other two models need to order. It is used to determine the surface hardness of wet mold sand (core), and provide technical parameters for developing molding process. According to the principle that the force of the spring is linear with the stroke, the distance of the stroke is expressed by the surface pointer through the transmission of a set of gears and racks. Sand surface hardness tester B The unit of type is (g/mm2), but is customarily not expressed in units but is expressed in hardness. Because their quantity values are related and consistent, the values of hardness are large when the unit value is large (g/mm2). Usage method: Adjust the 0 bit, when the pointer is not in the 0 bit, turn the adjustment ring, so that the pointer to 0. When used, the hardness is pressed in the sand on the test plane (axis hardness of the surface to be perpendicular to the plane of the sand), sand hardness meter gauge plane and the close contact. The pointer is stopped at a certain value, press the locking pin to lock, reading test a fixed value, and then releasing the locking pin so that the pointer reply 0. The determination was made at 3~5 times per assay, and then the average number was calculated, as well as the hardness of the part. Technical Parameter: Model: B type Compression stroke: 2.50mm Maximum load: 980G Load under pressure: 50g Head shape and size: Ball R12.70 Accuracy: When the pointer is at any value, the relative force of the pressure head is equal to + 5% When the pointer goes back to the 0 bit, the tolerance is 1 degrees Outline size: 90 x 55 x 28mm
