First, the gate of the mechanical strength test machine The test machine according to GB7251.5-2008, applied to the housing with a hinged door on the vertical plane for all types of mechanical strength test CDC door. Technical parameters: 1. Operating voltage: 220V/50HZ 2. Force is applied by: high torque stepper motor to push the screw, the screw on the device contradict force pushing guinea pigs, urging force reaches the set value, sustained 3s, automatic timing , automatically stops. 3 Display: 10-inch high definition touch screen PVA; 4. Applied force range :50-450N, Accuracy: ± 0.1N 5. Device configuration cross slide, you can down before and after the adjustment, stroke: 500mm; 6. Imposed time: 00-99S can be adjusted to reach the force is applied to the time automatically refunded. 7 can be close to the upper edge of the door hinge side load of 50N applied outside 300mm, continuous 3s, automatic timing; 8. Loads increased to 450N. . 9 The test machine test results determined manually by the user.
