Embodiment Construction

[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] The specific embodiment of the processing method of spiral protective band of the present invention, as image 3 and Figure 4 As shown, the pipe fitting blank used in the present invention for processing the spiral protection band 2 is a plastic hard pipe, and the lathe used is a common horizontal lathe, such as Figure 5 to Figure 8 As shown, the cutting tool 3 during processing includes two C-shaped cutter bodies 30. In this embodiment, the two C-shaped cutter bodies 30 have an integrated structure. The side of 31 is provided with a chip removal groove 32 between two C-shaped cutter bodies, and the main cutting edge 31 is an arc-shaped cutting edge. Through the relative circular rotation of the cutting tool 3 and the processing pipe blank, cutting water pipes and cutting edges are simultaneously realized. The purpose of edge chamfering.

Abstract

The invention provides a spiral protective belt machining method which comprises the following steps of cutting a pipe wall of a pipe fitting blank through a cutter, so that the pipe wall of the pipefitting blank and the cutter relatively move in the axial direction and the radial direction of the pipe fitting blank to ensure that a cutting track of the cutter is a cylindrical spiral line. A spiral protective belt is machined through cold machining, deformation caused by hot machining is avoided, and the problem of thermal deformation of the spiral protective belt in the prior art is solved.

Description

technical field [0001] The invention relates to a method for processing a spiral protection tape. Background technique [0002] The converter valve equipment is the key equipment in the HVDC transmission system, and the operation reliability of the converter valve equipment directly affects the working stability of the DC transmission system. The design of the water cooling system is a very important part of the overall design of the converter valve. The purpose of the design of the water cooling system is to dissipate all the heat loss generated by the converter valve under various operating conditions and ambient temperatures, so that the converter Valve temperatures are kept low, thereby enhancing reliability and improving power transfer capability. [0003] The cooling water flows through the diverter valve through the water pipe. In order to ensure the isolation of the potential, the water pipe is generally made of plastic material. These materials have the characteris...
