Pendulum impact testing machine

The device is manufactured in accordance with the requirements of Section 24.1 of GB2099.1-2008 and Section 20 of GB16915.1-2003.

parameter:

l The impact element has a hemispherical surface with a radius of 10m, the hemispherical surface is a polyamine product, the hardness is Rockwell hardness RH100, and the mass of the component is 150g ± 1g;

l The impact element is rigidly fixed to the lower end of the steel pipe with an outer diameter of 9 mm and a wall thickness of 0.5 mm, and a pivot is attached to the upper end of the steel pipe so that the steel pipe can only swing in a vertical plane;

l The axis of the pivot is located 1000mm ± 1mm ​​above the axis of the impact element. EMF tester

l The Rockwell hardness of the polyamide impact element is measured by a ball having a diameter of 12.700 mm ± 0.0025 mm.

l The initial load is 100N ± 2 N, and the additional load is 500N ± 2.5N (details on determining the Rockwell hardness of plastics are given by ISO 2039-2);

l The impact test device is designed to apply a force of 1.9N-2.0N to the surface of the impact element in order to maintain the steel pipe in a horizontal position;

l The nominal thickness of the plywood is 8mm, the length and width are about 175mm, and the top and bottom edges of the plywood should be firmly fixed to the rigid bracket of the mounting bracket;

l The mass of the mounting bracket is 10kg 1kg. The bracket is pivotally mounted on the rigid frame and the frame is fixed to the solid wall.

l Do it during installation:

l - the sample can be placed such that the impact point falls within a vertical plane through the axis of the pivot;

l - the sample can be moved horizontally and can be rotated about an axis perpendicular to the surface of the plywood;

l - The plywood can be rotated 60° in both directions about the vertical axis.

l The switch and switch box, wall mounted socket and surface mount box can be installed on the plywood according to normal use requirements; the specimens of the concealed switch and the concealed socket are mounted on a hardwood block or similar material. After the groove is installed, it is completely fixed to a plywood instead of being fixed to the corresponding mounting box.

l Hammer drop height: 100, 150, 200, 250mm, with a dial display.

The sample can be rotated 90° about its axis perpendicular to the plywood, and the plywood can be rotated 60° in each of two opposite directions.

l The steel part is 304 stainless steel and the frame is made of aluminum alloy.
