Embodiment 1

[0034] see Figure 1-Figure 7 , the present invention provides a technical solution: a novel thick plate rolling process, including selecting a steel plate 3 according to the drawing requirements, and then purchasing, blanking, groove opening and rolling process according to the steel plate 3, and the rolling process includes The following steps:

[0035] Step 1. Before rolling, it is necessary to check whether there is any debris on the surface of the conveying platform and the steel plate 3. If there is any, it needs to be cleaned in time. If it cannot be cleaned, it must be removed with a power tool;

[0036] Step 2. After inspection and processing, place the steel plate 3 between the upper roller 1 and the lower roller 2 of the plate bending machine, and push the plate forward, so that the edge of the steel plate 3 is in contact with the upper roller 1, and observe and measure The distance from the edge of the steel plate 3 to the upper roller 1, if the distance is not eq...

Abstract

The invention discloses a novel thick plate rolling technology. The technology comprises the following steps that a required plate is selected according to drawing requirements, purchasing, blanking, groove opening and rolling procedures are performed according to the selected plate, and the technology is characterized in that the rolling procedure comprises eight steps of cleaning, pressing head rolling, curved surface rolling, closed opening rolling and welding and the like. The plate is rolled and formed step by step through repeated adjustment of the descending pressure and height of an upper roll shaft, meanwhile, the head is directly pressed when the plate is rolled, the phenomenon that head pressing with allowance is required during rolling due to the fact that a plate rolling machine is insufficient in capacity is avoided, the plate cost is reduced, the time for removing the allowance is shortened, the rolling efficiency is greatly improved, and thus the production quality is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of wind power plate rolling technology, and in particular relates to a novel thick plate rolling process, applicable to tower tubes, single piles and jackets. Background technique [0002] In recent years, with the rapid development of the offshore wind power industry, the wall thickness of the foundation of the offshore wind turbine has become thicker, the diameter has become larger, and the material grade has become higher and higher. The requirements for the manufacturing capacity of the manufacturer have also continued to increase. The roll forming of the wall cylinder has always been the focus and difficulty of the basic manufacturing of sea breeze fans. At the present stage, the capacity of the plate rolling machine is insufficient in the manufacturing process, and it is difficult to determine the size of the blanking material and the size of the indenter, so that there is a lot of margin during the ro...
