Embodiment Construction

[0022] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments.

[0023] Please refer to figure 1 with figure 2 As shown, the new method for making the flange section of the short tube section of the offshore wind power tower in this embodiment, the specific method is as follows:

[0024] Step 1. The two short tube sections are blanked as a whole. Use a CNC machine tool to cut out two equal-length gaps 5 at intervals of about 2 horizontally at a cutting speed of 280-320 mm / min at the middle position of the blanked steel plate 1 using a CNC machine tool. , the bridge nodes 6 are left at both ends of the gap 5, and the length direction of the gap 5 is perpendicular to the length direction of the long tube flange section 4 to be fabricated;

[0025] Step 2. Use a semi-automatic flame cutting machine to cut the bevel, and polish and clean it with a grinder;

[0026] Step 3: St...

Abstract

The invention discloses a novel method for manufacturing short shell ring flange sections of an offshore wind power tower barrel. The method comprises the steps of steel plate cutting, groove processing, steel plate edge rolling and assembling, longitudinal seam welding, flange assembling, circular seam welding and integral cutting, and during steel plate cutting, a left gap and a right gap are respectively and horizontally cut at the middle position at an interval, broken bridge nodes are reserved at the two ends of each gap, and during integral cutting, the broken bridge nodes are cut off along the gaps, so that two short shell ring flange sections are separately manufactured. The manufacturing period of the short shell ring flange section is greatly shortened, the working efficiency is improved, and meanwhile the cutting accuracy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation, in particular to a new method for manufacturing a short section flange section of an offshore wind power tower. Background technique [0002] Offshore wind power towers are composed of multiple tube segments with flanges, and in the actual production process, the flange segments of the tube segments are generally made by welding and fixing the flanges with the adjacent single tube segment ring seams. [0003] Before welding the girth seam, it is necessary to place the single cylinder section and the flange between the two sets of roller frames; and the length of some short cylinder sections is less than the minimum distance between the two sets of roller frames, so they cannot be placed on the two sets of roller frames at the same time. A single group of roller frames can easily tilt the cylinder section, causing potential safety hazards. [0004] The Chinese patent docume...
