Technical Field
[0001] The utility model relates to the technical field of corundum production, in particular to a corundum compressive strength testing machine. Background Art
[0002] The compressive strength of corundum is an important parameter that measures its resistance to damage. Higher compressive strength means the material can withstand greater pressure and impact, and has better stability and durability. The compressive strength of corundum can be measured through specific experimental methods. Generally speaking, compressive strength can be measured using methods such as crushing tests or uniaxial compression tests. In these tests, the abrasive sample is placed between the upper and lower platens of a press and its compressive strength is measured by gradually increasing the pressure. By recording the relationship between the pressure and the deformation or fracture of the sample, the compressive strength of the abrasive can be determined.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1-5 As shown, a corundum compressive strength testing machine includes a workbench 1, the top surface of the workbench 1 is fixedly connected to a mounting frame 2, the top surface of the mounting frame 2 is fixedly connected to a hydraulic cylinder 3, the piston rod of the hydraulic cylinder 3 is fixedly connected to an extrusion head 4, and a placement platform 15 is fixedly connected to the center of the top surface of the workbench 1, and a limiting groove 16 is symmetrically provided at the bottom of the outer cylindrical surface of the placement platform 15. The bottom of the placement platform 15 is movably sleeved with a limiting ring 22, and a limiting block 21 that slides with the limiting groove 16 is symmetrically fixedly connected inside the limiting ring 22. A retaining ring 7 is provided on the top of the limiting ring 22. By arranging the retaining ring 7 structure on the placement platform 15, when the corundum is crushed during use of the device, debris will not splash, which not only makes the workbench 1 more tidy, but also eliminates the safety problems caused by the splashing of debris. A first compression spring 10 sleeved on the placement platform 15 is provided between the bottom of the limiting ring 22 and the top surface of the workbench 1.
[0023] The bottom of the outer cylindrical surface of the bottom of the retaining ring 7 is fixedly connected to the retaining ring 6, and the top surface of the workbench 1 is fixedly connected to the retaining frame 11 on both sides of the placement table 15. A fixing frame 12 is movably provided in the retaining frame 11, and one end of the fixing frame 12 is fixedly connected to the push plate 8. A second compression spring 9 is movably sleeved on the fixing frame 12 between the retaining frame 11 and the push plate 8, and a hook 14 is fixedly connected to the center of the other end of the fixing frame 12.
[0024] The limiting ring 22 is composed of two arc-shaped plates 17, one of which is provided with a slot 20 on the side wall of one of the arc-shaped plates 17, and the side of the other arc-shaped plate 17 is fixedly connected with an insert 19 that is engaged with the slot 20.

[0025] Working principle: When using the device, when placing materials, place the materials in the baffle ring 7, and then the hydraulic cylinder 3 drives the extrusion head 4 to descend into the baffle ring 7 to extrude the corundum. During crushing, the baffle ring 7 can block the debris to avoid splashing. When taking out the crushed corundum, press the baffle ring 7 downward to engage the snap ring 6 on the baffle ring 7 with the hook 14, and the placement table 15 will leak out, so that the corundum can be operated. Then press the push plate 8 to separate the snap ring 6 from the hook 14. Under the action of the first compression spring 10, the baffle ring 7 can be lifted up for the next operation.
