Problems solved by technology

[0002] Some existing large-scale rotary equipment cannot achieve precise positioning and smooth operation of the equipment due to the limitation of the manufacturing accuracy of the basic guide rails.
For the circular guide rails of some large and heavy-duty slewing equipment, it is generally realized by segmented processing and on-site splicing. Due to the split structure between the segments, the overall stability of the guide rails is not high, and the overall accuracy of the upper surface is relatively high. Difference

Embodiment Construction

[0026] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0027] In this example, see the attached figure 1 , 3 As shown, the center diameter of the guide rail surface is 19.5m, the width of the guide rail surface is 190mm, the overall flatness of the guide rail surface is required to be 0.25mm, and the bearing capacity is greater than 550 tons. It consists of 20 sections of monorail parts 1 welded to form a whole. The design and manufacture are divided into six steps: monorail part 1 design, welding groove design, monorail part 1 manufacturing, guide rail installation, guide rail welding, and U-shaped weld 2 grinding, as follows:

[0028] Step 1. Monorail part 1 design

[0029] The material of monorail part 1 is high-strength steel 42CrMo, which has been quenched and tempered, and has good toughness and impact resistance. The cross-sectional size is 400mm×210mm, adopts circular ...

Abstract

The invention discloses a preparing method of a whole welding type guide rail. The whole welding type guide rail serves as a motion basis of a certain large rotation device, and has the advantages ofbeing large in diameter, high in precision and stability and the like. The basis problems about high-precision motion and precision positioning of the certain large rotation device can be solved, a main structure is formed through whole welding of multiple segments of single-rail parts, and the design and manufacturing process comprises the six steps of single-rail part design, welding groove design, single-rail part manufacturing, guide rail mounting, guide rail welding, U-shaped welding line grinding and the like. Guide rail mounting and guide rail welding serve as key processes, and the method has the important significance in ensuring precision and stability of the whole guide rail.

Description

technical field [0001] The invention relates to a method for preparing a welded integral guide rail, which belongs to the technical field of product forming. Background technique [0002] Some existing large-scale rotary equipment cannot achieve precise positioning and smooth operation of the equipment due to the limitation of the manufacturing accuracy of the basic guide rails. For the circular guide rails of some large and heavy-duty slewing equipment, it is generally realized by segmented processing and on-site splicing. Due to the split structure between the segments, the overall stability of the guide rails is not high, and the overall accuracy of the upper surface is relatively high. Difference. Contents of the invention [0003] The present invention is aimed at the deficiencies in the above-mentioned prior art and provides a method for preparing a welded integral guide rail. The purpose is to weld the guide rail as a whole. mm, because it is a feature of the over...
