Description

Technical Field

[0001] The utility model relates to the field of hydraulic pipe fitting testing, in particular to a strength testing device for hydraulic pipe fitting production. Background Art

[0002] Hydraulic pipe fittings play a very important role in hydraulic systems. Hydraulic pipe fittings need to be tested for compressive strength during the production process in order to record the performance data of hydraulic pipe fittings. In order to improve the test efficiency, strength testing devices are often used to perform the operation. Although some of the hydraulic pipe fitting strength testing devices currently used can meet the test needs, they still have certain defects in actual use;

[0003] For example, the patent for a strength test device for hydraulic pipe production provided by the authorization announcement number CN218003117U can not only facilitate the limit of the hydraulic pipe for pressure testing, improve the stability during testing, and ensure the accuracy of the test results, but also facilitate observation during the strength test of the hydraulic pipe, improve safety, further improve the test accuracy, and reduce the difficulty of fine-tuning the strength test of the hydraulic steel pipe;

[0004] However, this patent can only perform strength tests on the end faces of hydraulic pipe fittings. If the surface of the hydraulic pipe fittings needs to be tested, it is not easy to fix the pipe fittings, and the surface test effect is poor, which needs to be improved. Therefore, a strength testing device for hydraulic pipe fittings production is now proposed. Utility Model Content
