Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a flange grinding device. Background Art

[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. There are also flanges used on the inlet and outlet of equipment, which are used to connect two devices, such as reducer flanges. Flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline devices. When used on equipment, it refers to the inlet and outlet flanges of the equipment. There are holes on the flange, and bolts connect the two flanges tightly. Gaskets are used to seal between flanges. Flanges are divided into threaded connection (threaded connection) flanges, welding flanges and clamping flanges. Before the flanges are produced and put into use, the burrs on their surfaces need to be polished to ensure the sealing of the pipe connection. A common method used by technicians in this field is to design a grinding device or equipment, such as the authorized patent CN202321559302.3, a flange corner grinding device, which can solve the grinding problem well. However, if the product model is single, single-sided and inner diameter grinding, or grinding in the form of a mold limiter, is used less than the above-mentioned patented parts, which can save costs and simplify maintenance.
