Description

Technical Field

[0001] The utility model relates to the technical field of flexural testing, in particular to a digital brick and tile flexural testing machine. Background Art

[0002] Digital flexural testing machine is a kind of testing equipment for testing the flexural and compressive properties of materials. With the development of science and technology, the flexural testing machine has changed from the previous method of manually recording data and performing calculations to autonomous calculations and directly displaying the results, which improves the convenience of test operations.

[0003] However, in actual use, the existing digital flexural testing machines still have shortcomings that need to be improved. A typical example is that when testing bricks and tiles, the existing digital flexural testing machines will encounter problems such as stuck materials and excess materials that cannot be removed in time, causing blockage. In addition, bricks and tiles need to be clamped horizontally at both ends during the flexural test, and the squeezing after the two ends are clamped horizontally will affect the test data. Therefore, a digital brick and tile flexural testing machine is proposed. Utility Model Content

[0024] Both ends of the extrusion block 11 are slidably connected to the guide block 4. The extrusion block 11 is above the discharge plate 5. A reciprocating motor 12 is fixedly connected to the inner side of the base 1. A lifting slide column 13 is fixedly connected to the output end of the reciprocating motor 12. An eccentric wheel 14 is fixedly connected to the upper end of the lifting slide column 13. A traction frame 15 is slidably connected to the surface of the eccentric wheel 14.

Start the clamping motor 6 to drive the cam 9 to rotate through the active sprocket 7, so that the cam 9 pushes the extrusion block 11 to clamp the experimental bricks and tiles.
