眼鏡架拉強度試驗機(jī)Gles frame tensile strength test machine參考標(biāo)準(zhǔn)：GB/T14214：2003等等
測試目的：測定鏡架的連接部位具備的拉功能，鏡框因拉壓而損壞，確保鏡架可正常使用2年或以上。重點針對焊點和相應(yīng)要求重點檢測的非焊接的連接處。
測試方法：
1、用夾具按要求夾住鏡架（因具體測試內(nèi)容不同，夾具位置也不相同，例如：兩鏡腿距離鉸鏈20mm處）；
2、設(shè)定參數(shù)（拉升速度、拉力值大小等）
3、啟動儀器，待儀器自動緩慢施加拉力至98N後停止；
    4、觀察鏡架狀況，鏡架各部位應(yīng)無斷裂、脫落等不良現(xiàn)象。
關(guān)鍵參數(shù)：
    1. 測試眼鏡結(jié)構(gòu)接著點是否凝固與材料本身的拉力。
    2. 可做 拉、擠壓的測試。
    3.有3種測試重量單位:可供選擇:公斤、磅、N(牛頓)。
    4.提供不同夾具，可分別測試鏡圈、金屬架、板材架等。
    5.尺寸:55×33×75 CM(長×寬×高)
    6.重量:80 Kg
    7.電源：AC220V 50Hz
8.產(chǎn)地：廣東

 

Reference standard: GB/T14214:2003 etc.

The purpose of testing: Determination of frame joints with certain tensile function, prevent frame because of pressure damage, to ensure that the frame can be normal and safe use of 2 years or more. Focusing on the solder joints and the corresponding requirements focus detection non welded joints.

Test method:

1, jig as required ( specific test clamp frames for different content, fixture position is not the same, such as: the two gles leg distance hinge 20mm );

2, setting parameters ( lifting speed, tension value etc.)

3 In  the starting apparatus, the apparatus automatically slow tensile force is applied to the 98N after the cessation of;

4, observe the status of each frame, frame parts should be no fault, shedding phenomena.

Key parameter:

1 test gles structure then is solidified and material tensile strength.

2 can be pulled, extrusion test.

3 3 test unit of weight: options: kg, pound, N ( Newton ).

4 different fixture, can test mirror ring, metal frame, plate racks.

5 dimensions: 55 x 33 x 75 CM ( length * width * height )
