Measurement performance requirements
1. The parallelism of the axis shaft and the reference surface of the test machine should be within 1/1000. The project should be given by the manufacturer inQualification Certificate ; 2. When the hammer is freely suspended, the impact knife blade and trial The gap should be within ± 0.5mm;
3. The parallel degree of the side of the hammer and the swinging plane, and the verticality requirements of the sample support from the sample support are shown in the figure below;
4. The impact of the blade should be on the plane of the span center
. Essence When the hammer swing freely, the angle of the blade and the vertical axis of the sample shall be 90 ° ± 2 °; 5. 6. The radial gap at the bearing of the bearing should not exceed 0.08mm.
Put the hammer impact test machine use:
Substation of hammer impact test machine Also known as cantilever beam shock test machine is mainly used for hard plastic (including plate materials, pipes, plastic heterogeneous materials), enhanced nylon, glass fiber reinforcement, ceramics, cast stones The determination of the impact toughness of non -metallic materials such as electrical insulation materials is an ideal test equipment used by the chemical industry, scientific research units, and colleges and universities for material performance testing.
Placing Hammer impact test machineFeature The technical parameters fully meet the requirements of ISO180, IOS2611, JB/T8761, ASTM D256 and other standards. Touch screen control, simple structure, convenient operation, accurate data, and miniature printing are several major features of this test machine.
