Description

Technical Field

[0001] The utility model relates to the field of cold-rolled coil material detection equipment, in particular to a detection device supporting cold-rolled coil materials of multiple thicknesses. Background Art

[0002] Cold rolled coil testing equipment usually includes the following:

[0003] 1. Thickness gauges: These are used to accurately measure the thickness of cold-rolled coils to ensure they meet production standards and customer requirements. For example, laser thickness gauges utilize laser technology for non-contact measurement, enabling fast and accurate thickness readings. Contact thickness gauges measure thickness through direct contact between the probe and the coil.

[0004] 2. Surface defect detector: Checks the surface of cold-rolled coils for scratches, cracks, holes, rust spots and other defects. Commonly used optical surface defect detectors use high-resolution cameras and image processing technology to identify and analyze defects.

[0005] 3. Hardness tester: measures the hardness of cold-rolled coils to evaluate their mechanical properties; such as Rockwell hardness tester and Vickers hardness tester;

[0006] 4. Roughness tester: measures the roughness of the coil surface to ensure its surface quality;

[0007] 5. Chemical composition analyzer: Analyze the chemical composition of cold-rolled coils to ensure that the composition of the materials meets the specified standards;

[0008] 6. Tensile testing machine: used to test the tensile properties of cold-rolled coils, such as tensile strength, yield strength, elongation, etc.

[0009] Taking a hardness tester as an example, by placing the cold-rolled coil on the workbench of the hardness tester, the digital display instrument moves downward, and its end contacts the surface of the cold-rolled coil. The hardness value can be displayed on the screen of the digital display instrument. However, in actual operation, after the detection end completes the detection of one point on the surface of the cold-rolled coil, the clamp needs to be released and the position of the cold-rolled coil needs to be adjusted to detect the hardness of another point on the cold-rolled coil. The operation is time-consuming and labor-intensive, and there is room for improvement. Utility Model Content

The arrangement of the accommodating groove 8, the positioning groove 81 and the mobile seat 91 can make the detection head 4 move downward four times, and can perform uniform pressure hardness testing on the four points on the surface of the cold-rolled coil 11, thereby improving the accuracy of the hardness test on the cold-rolled coil 11. The operation is simple and fast, saving time and effort.
