Description

Technical Field

[0001] The utility model relates to the technical field of boards such as fiber cement boards / calcium silicate boards, and in particular to a device for testing the impact resistance of boards. Background Art

[0002] With the continuous development of social construction, various types of panels have been widely used in residential, industrial, public and other buildings. These panels usually need to have excellent impact resistance to ensure structural safety and functional integrity.

[0003] Impact resistance can directly reflect, evaluate, or determine a sheet's impact resistance, brittleness, and toughness. Panel manufacturers typically evaluate their products' impact resistance using methods such as digital pendulum impact testing machines, pendulum impacts on entire panels using a support frame, or simple drop-ball impacts. Some of these methods suffer from issues like small specimen sizes, lack of overall representativeness, and significant discrepancies in test results. Others require large footprints, incur significant losses, are inconvenient to install and disassemble, and require cumbersome manual operation. Furthermore, they face challenges such as inaccurate impact height and impact point, and large operational errors. Therefore, in response to these technical challenges, this application proposes a more convenient, intuitive, and reliable device for testing the impact resistance of sheet metal.

A stop block 36 is movably inserted into the stop positioning hole 37 to block or prevent the heavy hammer member 35 from flying.

[0026] In this embodiment, at least one, preferably two, pressure plate members 12 are provided on each side of the fixing seat 1. The pressure plate member 12 is connected to the fixing seat 1 by a preset tightening bolt.
