XJL—300B落錘沖擊試驗(yàn)機(jī)產(chǎn) 品 詳 細(xì) 介 紹:
一、落錘沖擊試驗(yàn)機(jī)用途:
落錘沖擊試驗(yàn)機(jī)用于對(duì)塑料管材、板材和制品進(jìn)行沖擊試驗(yàn),以評(píng)定這些材料的抗外力沖擊性能。該機(jī)控制部分采用數(shù)控技術(shù),能數(shù)字予置和顯示沖擊高度、自動(dòng)對(duì)零、升錘、落錘、沖擊并能有效地防止二次沖擊。采用雙柱式結(jié)構(gòu),其結(jié)構(gòu)緊湊、能量損失小、試驗(yàn)速度快。
二、落錘沖擊試驗(yàn)機(jī)符合標(biāo)準(zhǔn):
符合JB/T9389標(biāo)準(zhǔn)要求的落錘沖擊試驗(yàn)機(jī)技術(shù)條件,并滿足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等標(biāo)準(zhǔn)規(guī)定的試驗(yàn)方法的要求。
定義:
真實(shí)沖擊率:整批產(chǎn)品進(jìn)行試驗(yàn)時(shí),其沖擊破壞總數(shù)除以沖擊總數(shù)即為真實(shí)沖擊率,以百分?jǐn)?shù)表示。
破壞:用肉眼觀察,試樣經(jīng)沖擊產(chǎn)生裂紋、裂縫或試樣破碎稱為破壞,因落錘沖擊而形成的試樣凹痕或變色則不認(rèn)為是破壞。
三、落錘沖擊試驗(yàn)機(jī)工作原理:
落錘沖擊試驗(yàn)機(jī)以規(guī)定質(zhì)量和尺寸的落錘從規(guī)定高度沖擊試驗(yàn)樣品規(guī)定的部位,即可測(cè)出該批(或連續(xù)擠出生產(chǎn))產(chǎn)品的真實(shí)沖擊率。此試驗(yàn)方法可以通過改變落錘的質(zhì)量和或改變高度來滿足不同產(chǎn)品的技術(shù)要求。TIR允許值為10%。
四、落錘沖擊試驗(yàn)機(jī)主要性能指標(biāo):
1、錘體質(zhì)量:0.5kg、1.25kg、1.6kg、2kg、2.5kg、3kg、3.2kg、4kg、5kg、6kg、6.3kg、8kg、10kg、12.5kg、15kg

5、沖擊高度:0mm-2000mm
6、沖擊中心與夾具中心偏差:≤1mm
7、托板型式:120°V型或帶支承、夾具平型托板
8、電 源:AC220V 50Hz
9、外形尺寸:750mm×550mm×3500mm
10、凈 重:280kg
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
