Milling tool for end surface of pipe material

Abstract

The invention relates to a milling tool for the end surface of a pipe material. The front part of a tool handle is provided with a tool clamping end and an anti-shake end with a smaller diameter, and the middle part of the tool clamping end is provided with a square hole for installing the tool. The tool is of a cuboid structure. Two ends of the tool are respectively provided with symmetrical tool bits, and a concave circular groove is formed in the center of the tool. An anti-shake ring is arranged outside the anti-shake end, a screw penetrates through a screwed hole in the middle part of the anti-shake end and is screwed, and the circular head of the end part of the screw abuts with the concave circular groove formed in the tool. The tool handle, the tool clamping end and the anti-shake end are of an overall structure, are machined based on the current conventional tool clamping piece and are convenient to manufacture and low in cost. As the anti-shake ring is arranged outside the anti-shake end, the problem that the machining face is uneven due to the shake of a drill bit in the cutting process is effectively solved in the using process of the tool. The milling tool for the end surface of the pipe material has the advantages of high processing efficiency, good cutting quality and capacity of effectively improving the machining quality of the end surface of the pipe material.

Description

technical field [0001] The invention relates to the field of chemical machinery manufacturing, in particular to a tube head flattening processing device applied to heat exchange tubes of shell and tube heat exchangers. Background technique [0002] The connection between the heat exchange tube and the tube sheet of the shell-and-tube heat exchanger can be in the form of strength welding, strength expansion joint or welding and expansion joint. In order to ensure the processing quality and connection strength of the heat exchange tube and the tube sheet connection In the connection process, it is required that the protruding length of the heat exchange tube and the tube sheet should be consistent. If the heat exchange tubes are not cut neatly or the assembly gap between the heat exchange tubes and the tube sheet is uneven, the length of the heat exchange tubes and the protruding tube sheets will be uneven and uneven. On the one hand, it will affect the quality of the product,...
