Detailed process of tensile test of Jinan universal testing machine

Hydraulic universal testing machineIt is a high-tech testing equipment. It is often used in various industries in production and manufacturing to check whether the product is qualified. The universal testing machine has multifunctional advantages and can conduct tests of a variety of materials. The following is the adjustment process for tensile testing:

Hydraulic universal testing machineThe stretched cross beam includes two upper beams, two lower beams, two uprights and two lead screws. The upper beam is fixed to the upper column and the upper screw, and the lower beam is fixed to the lower column and the lower screw. The upright and the lead screw are placed diagonally. The upper stretching attachment installed between the upper beams and the lower stretching attachment installed between the lower beams. A transmission nut is installed on each lower beam. The upper end of the transmission nut is fixed with a gap adjustment nut through a screw with a spring. After confirming that the installation level of the instrument meets the requirements of the regulations, first check whether the friction in the working part is too large. If so, the guide wheel clearance should be adjusted to eliminate friction. If necessary, clean the working oil cylinder. If there is still a positive difference after eliminating the influence of friction, the tightening screws of the swing rod and the push plate connecting the sleeve in the force measuring part (reading mechanism) should be loosened, and the push plate should be adjusted to the inside. After tightening the tightening screws, the small disc is checked step by step, and repeated several times until the calibration is passed. If the small disc is qualified and the large and medium discs are still exceeding the difference, the weight of B and C thallium should be appropriately increased until the calibration is passed.
