High-strength bolts test fixture

High-strength bolts of the test fixture is developed according to national standards GB / T3098.1-2010, use of special materials designed produced by processing it through a combination of different ways, you can wedge bolt load test and the general tension test, bolts guaranteed minimum tensile load test, load test to ensure the nut. Within the clamp by connecting rod clamped to the universal testing machine jaws, which can be a variety of tension test, general hydraulic universal testing machine without adding or changing other devices. Second, the main technical indicators: 1, the wedge test maximum tensile load: 696kN (M30-10.9s) 2, bolt minimum tensile load test: 583kN (M30-10.9s) 3, nut ensure load test: 583kN (M30-10.9) 4 bolts ensure load test: 466kN (M30-10.9s) Note: M30 high-strength bolts above the test fixture to be special order. Third, the fixtures configuration: 1, the clamp (with lever) one pair (of 4) 2 pad M10 \ M12 \ M14 \ M16 \ M18 \ M20 \ M22 \ M24 \ M27 \ M30 each one (total 10 ) 3, tension ring with internal thread M10 \ M12 \ M14 \ M16 \ M18 \ M20 \ M22 \ M24 \ M27 \ M30 each two (20) 4, wedge load block M10 \ M12 \ M14 \ M16 \ M18 \ M20 \ M22 \ M24 \ M27 \ M30 each pair (2 / pay, 20) M20 following is 10o, 6o M22 (including M22) above is 4o, 6o 5, nut test mandrel M10 \ M12 \ M14 \ M16 \ M18 \ M20 \ M22 \ M24 \ M27 \ M30 each one (of 10) (another gift M33 pull a wire loop, a total of 65 full set of fixtures
