Drop hammer impact testing machine, suitable for measuring the external impact resistance of sheet metal.

The product complies with the national standard GB11548-1989 Test method for impact resistance of rigid plastic sheets (drop hammer method).

This machine adopts PLC control, dual tube guiding structure, 10 inch LCD display, and has functions such as automatic hammer suction, automatic lifting, and prevention of secondary impact; Reasonable design, beautiful appearance, stable performance, and convenient operation.

1. Adjustable working table, automatically nulling and lifting function for testing sample

2. Induction brake motor drive, chain drive, smooth and reliable lifting for weights.

3. Use imported PLC as control element to control the hammer height and auto-detect hammerhead height

4. Automatically locate, auto zero, auto-lifting the hammer before and after the impact, highly automated, easy to operate.

5. Using standard polished rodas guide device,low resistance when the hammer fall

6. Can be updated with safety devices to ensure safe operation

7. Optional function: Anti-secondary-impact device, can automatically prevent secondary impact caused by High elastomer specimen

1. Hammer body mass: 1kg/2kg/3kg/4kg/5kg/6kg/7kg/8kg/9kg/10kg/15kg, with an accuracy of ± 5g

2. Hammer head: There are three types: A, B, and C, as shown in Figure 2, which can be replaced as needed, and the hardness is not less than HRC54

3. Test fixture: ① The test fixture is mainly composed of two circular ring shaped clamping plates, corresponding to three types of hammers A, B, and C. Its inner diameters are 80 ± 2.0mm, 130 ± 2.5mm, and 40 ± 1.0mm, respectively. The chamfer of the inner hole in contact with the sample is not greater than 0.8mm (as shown in Figure 3). ② The upper and lower clamping plates of the fixture are concentric, and the fixture can clamp the sample to ensure that it does not displacement when impacted
