XJL—300B落锤冲击试验机产 品 详 细 介 绍：
一、落锤冲击试验机用途：
落锤冲击试验机用于对塑料管材、板材和制品进行冲击试验，以评定这些材料的抗外力冲击性能。该机控制部分采用数控技术，能数字予置和显示冲击高度、自动对零、升锤、落锤、冲击并能有效地防止二次冲击。采用双柱式结构，其结构紧凑、能量损失小、试验速度快。
二、落锤冲击试验机符合标准：
符合JB/T9389标准要求的落锤冲击试验机技术条件，并满足GB/T5836.1、GB/T10002.1、GB/T1002.3、GB/T13664、GB/T16800、GB/T6112、GB/T14152、ISO 4422、ISO 3127、BS EN 1411、BS EN 744等标准规定的试验方法的要求。
定义：
真实冲击率：整批产品进行试验时，其冲击破坏总数除以冲击总数即为真实冲击率，以百分数表示。
破坏：用肉眼观察，试样经冲击产生裂纹、裂缝或试样破碎称为破坏，因落锤冲击而形成的试样凹痕或变色则不认为是破坏。
三、落锤冲击试验机工作原理：
落锤冲击试验机以规定质量和尺寸的落锤从规定高度冲击试验样品规定的部位，即可测出该批（或连续挤出生产）产品的真实冲击率。此试验方法可以通过改变落锤的质量和或改变高度来满足不同产品的技术要求。TIR允许值为10%。

The products of XJL-300B drop hammer impact testing machine are introduced in detail.
Application of drop hammer impact tester:
The drop hammer impact tester is used to test the impact properties of plastic pipes, sheets and products in order to evaluate the impact resistance of these materials. The control part of the machine adopts numerical control technology, which can digitally preset and display the impact height, automatically zero, lifter, drop hammer, impact and effectively prevent secondary impact. The double-column structure has compact structure, small energy loss and fast test speed.
2. The drop hammer impact testing machine meets the standards:
It meets the requirements of JB/T9389 and the test methods specified in GB/T5836.1, GB/T10002.1, GB/T1002.3, GB/T13664, GB/T16800, GB/T6112, GB/T14152, ISO 4422, ISO 3127, BS EN 1411 and BSEN 744.
Definition:
Real impact rate: When the whole batch of products are tested, the total number of impact damage divided by the total number of impact is the real impact rate, expressed in percentage.
Damage: Observed by naked eyes, cracks or sample breakage caused by impact are called damage, while notches or discolorations caused by drop hammer impact are not considered damage.
3. The working principle of drop hammer impact tester:
The drop hammer impact tester can measure the real impact rate of the batch (or continuous extrusion) products by the drop hammer of specified quality and size from the specified position of the impact test sample at specified height. This test method can meet the technical requirements of different products by changing the quality and height of drop hammer. The maximum allowable value of TIR is 10%.
4. Main performance indicators of drop hammer impact tester:
1. Weight of hammer: 0.5kg, 1.25kg, 1.6kg, 2kg, 2.5kg, 3kg, 3.2kg, 4kg, 5kg, 6kg, 6.3kg, 8kg, 10kg, 12.5kg, 15kg
2. Hammer radius: R5mm, R10mm, R30mm, R50mm
3. Workbench stroke: 0mm-400mm 0-630mm (optional)
4. Sample diameter: 10mm~400mm 0-630mm (optional)
5. Impact height: 0mm-2000mm
6. Deviation between impact center and fixture center: <1mm
7. Bracket type: 120 degree V or flat bracket with support and fixture
8. Power supply: AC220V 50Hz
9. Shape size: 750mm *550mm *3500mm
10. Net weight: 280 kg
