Description

Technical Field

[0001] The utility model relates to the technical field of ductile iron, in particular to a ductile iron casting performance test detection device. Background Art

[0002] Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used to cast some parts with complex forces and high requirements for strength, toughness and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material second only to gray cast iron. The so-called "iron instead of steel" mainly refers to ductile iron. The ductile iron performance test and detection device is a device used to perform various performance tests and tests on ductile iron materials. Different performance indicators require different test methods and detection devices for evaluation and detection. Impact tests are usually used to measure the toughness and impact resistance of ductile iron under impact loading. The impact tester measures the fracture toughness or toughness index of the sample, such as the impact energy absorption capacity, by applying an impact load, and indirectly evaluates the strength and hardness properties of the material.

[0003] Prior art publication number CN220367088U discloses a ductile iron performance test and detection device, including a workbench, two support plates are fixed on the upper end surface of the workbench, a guide rod is fixed between one side of the two support plates, a sliding sleeve is sleeved on the surface of the guide rod, a screw rod is rotatably installed between the other sides of the two support plates, a threaded tube is threadedly engaged on the surface of the screw rod, a moving frame is fixed on the upper end surface of the threaded tube, a motor is fixed on one side of the support plate, and a fixed frame is fixed at one end of the upper end surface of the workbench.

[0004] In the above-mentioned device, the workpiece is directly placed on the fixed frame and the movable frame without fixing the two ends of the workpiece. During the impact detection, the workpiece is easily displaced due to vibration. After the displacement, the impact detection point changes accordingly, affecting the detection result. At the same time, there is a risk of the workpiece falling from the fixed frame and the movable frame. In addition, the impact detection component in the above-mentioned device can only move horizontally, which results in that the detection can only be performed in the length direction of the workpiece. The sample data obtained from the detection is relatively single, which is not conducive to the comprehensive analysis of the workpiece performance. Utility Model Content
