Cylindrical core sample cutting method

Abstract

The invention relates to a cylindrical core sample cutting method, which comprises the following steps of: first axially positioning a cylindrical core sample in a way that an axial lead of the cylindrical core sample is parallel to that of a cutting saw blade; then making the cutting saw blade and the cylindrical core sample perform radial relative movements, and after vertically feeding the cylindrical core sample by a certain length, making the cutting saw blade and the cylindrical core sample perform relative circumferential cutting motions; and finally continuing to feed the cylindrical core sample by a certain length and making the cutting saw blade and the cylindrical core sample continue to perform the relative circumferential cutting motions until the cylindrical core sample is transversely cut into parts. As the cylindrical core sample is cut layer by layer from a radial circumferential surface to an axis in such a way, the method has the advantages of avoiding damage to an included angle between the circumferential surface and the end face of the core sample, ensuring the planeness of the cut end face, protecting and saving cutting materials, and improving accuracy, fairness and engineering timeliness in detection operation, along with application to the operation in the detection and sampling of various materials.

Description

technical field [0001] The invention relates to a cutting method, in particular to a cylindrical core sample cutting method. Background technique [0002] At present, when we want to cut the cylindrical core sample into sections, we first fix the cylindrical core sample through the fixture, or transport the cylindrical core sample in the plane and axial direction on the workbench, and then use the cutting wheel to cut the core sample vertically to the bottom, so that The angle between the end surface of the core sample and the circumferential surface is damaged, and the end surface of the core sample may also be uneven due to lack of exact positioning. At the same time, the cut material is likely to have cracks, which make the cut material not conform to Requirements, the qualification rate of materials is greatly reduced, and the waste is serious. When it is used for testing, it must be re-sampled, but some components may not be re-sampled, which seriously affects the accur...

[0002] At present, when we want to cut the cylindrical core sample into sections, we first fix the cylindrical core sample through the fixture, or transport the cylindrical core sample in the plane and axial direction on the workbench, and then use the cutting wheel to cut the core sample vertically to the bottom, so that The angle between the end surface of the core sample and the circumferential surface is damaged, and the end surface of the core sample may also be uneven due to lack of exact positioning. At the same time, the cut material is likely to have cracks, which make the cut material not conform to Requirements, the pass rate of materials is greatly reduced, and the waste is serious. When used for testing, it is necessary to re-sample, but some components may not be re-sampled, which seriously affects the accuracy, fairness and timeliness of the project.
