Description

Technical Field

[0001] The utility model belongs to the technical field of cutting tools, in particular to a portable sealing gasket cutting tool. Background Art

[0002] Sealing gaskets are used in fluid environments such as machinery, equipment, and pipelines, primarily to provide a seal. These gaskets are typically made from metal or non-metallic sheets and processed through processes such as cutting, stamping, or shearing. They are used to seal connections between pipelines and between mechanical components of machinery and equipment. Sealing gaskets can be categorized by material type: metallic or non-metallic. Common metallic gaskets include copper, stainless steel, iron, and aluminum, and are suitable for high-pressure and high-temperature applications. Non-metallic gaskets include asbestos, non-asbestos, paper, and rubber. Rubber gaskets are a common sealing component, offering resistance to high temperatures, oils, and acid and alkali corrosion. They are widely used in machinery, the petrochemical industry, and the automotive industry. When selecting a gasket, many factors should be considered, including temperature, application, media, and pressure. Temperature is the primary consideration during the selection process, as it can quickly narrow the selection process. Application parameters such as flange type and bolts also affect the sealing performance of the gasket. The corrosive, oxidizing, and permeable properties of the medium also need to be considered. Pressure is also a crucial factor in selection. Each gasket has a maximum pressure rating, and selection must be based on the pressure of the fluid within the system. Gasket installation is also crucial for ensuring a successful seal. Before installation, ensure that the flange or threaded connection, static sealing surfaces, and gaskets are inspected and that all other valve components are intact. During installation, ensure that the sealing surfaces, gaskets, threads, and rotating parts of bolts and nuts are coated with a layer of graphite powder or a lubricant mixed with graphite powder and engine oil (or water). The gasket should be installed correctly and centered on the sealing surface, without any deviation, protrusion into the valve cavity, or resting on the shoulder. Furthermore, the gasket's inner diameter should be larger than the inner hole of the sealing surface, and its outer diameter should be slightly smaller than the outer diameter of the sealing surface to ensure uniform pressure on the gasket.

[0003] Currently, circular gaskets are widely used in various equipment. Conventional gaskets need to be custom-made at the factory, which has a long production cycle. Especially when repairing these equipment, if these round gaskets are custom-made, it will greatly extend the equipment maintenance period, causing unnecessary losses to the maintenance unit and the user manufacturer. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the utility model provides a portable sealing gasket cutting tool that adopts a structure similar to a vernier caliper. A pointed cone is processed on the vernier to locate the center point of the cutting sealing gasket. A paper cutting blade is installed on the left side of the main body, with the tip of the blade at the same height as the vernier cone, and the blade is fixed with a butterfly bolt. When making a sealing gasket, you can first use the tool to measure the size of the gasket. For example, to measure the outer diameter of the gasket, you can read the underlined size in the tool. When making it, because it is different from the reference of the measured value, it is necessary to use the long scale line as the reference reading. Pull the vernier to the required sealing gasket radius size, lock the vernier, and cut the sealing gasket with the vernier cone as the center and the blade edge as the radius. This solves the problem that conventional sealing gaskets need to be customized in the factory and have a long production cycle. Especially when repairing these equipment, if these circular sealing gaskets are customized, it will greatly extend the maintenance period of the equipment, causing unnecessary losses to the maintenance unit and the user manufacturer.
