Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a large-diameter flange reaming device for offshore wind power comprises a reaming core rod 1 and an operating machine 4, wherein the reaming core rod 1 comprises a first column body 10, a transition body 11 and a second column body 12 which are coaxially connected in sequence;

further, the radius of the first cylinder 10 is smaller than that of the second cylinder 12;

specifically, in this embodiment, the first cylinder 10 has a diameter of 600mm and a length of 2200mm, the second cylinder 12 has a diameter of 800mm and a length of 3000mm, and the blank is forged by the first cylinder 10 and the second cylinder 12 in sequence to reach a predetermined size;

the transition body 11 is a circular truncated cone, and the radiuses of the end parts of the two ends of the transition body 11 are respectively the same as those of the first column body 10 and the second column body 12;

specifically, the length of transition body 11 is 150mm, and its angle is 45, and in the actual reaming process, after the forging of blank through first cylinder 10, need carry out the leveling height through transition body 11 earlier, accomplish the smooth and smooth transition of blank, done the preparation work through second stage reaming, guarantee reaming quality.

Further, a chamfer 7 is arranged at the end part of the first cylinder 10, which is far away from the second cylinder 12, and the chamfer 7 is R50, namely, the edge at the end part of the first cylinder 10 is cut into a cylindrical surface with the radius of 50 mm; in the actual operation process, the blank needs to be translated on the reaming core rod 1, and the edge at the end of the first cylinder 10 is set to be a chamfer, so that the situation that the inner hole of the blank is scratched by the edge of the first cylinder 10 in the inserting process and is folded in the transition process can be avoided;

specifically, through setting up reaming plug 1, compare with traditional saddle reaming technology, a fiery time saddle reaming's flow has been reduced, the clamping number of times has just also been reduced, according to the data display of forging technology, the forging temperature of flange often keeps between 800 to 1200 degrees, under the operational environment of so high temperature, if the clamping number of times is too much, cause the injured condition of staff easily, the security of production has been improved to a certain extent, work efficiency has also been improved simultaneously, the time of wasting on the clamping has been reduced, in addition also need not to use the clamping frock that matches with the reaming plug of different specifications, manufacturing cost has also been reduced, the practicality has been increased substantially.

One end of the reaming core rod 1 is clamped by an operating machine 4;

furthermore, a clamping jaw 5 is arranged in the manipulator 4, a connecting shaft 6 is arranged in the clamping jaw 5, and the connecting shaft 6 is coaxially connected with the tail end of the second column 12;

specifically, the clamping jaw 5 and the reaming core rod 1 are fixed by the connecting shaft 6, when the blank material is translated along the reaming core rod 1, the manipulator 4 needs to be controlled, the reaming core rod 1 fixed by the clamping jaw 5 is lifted upwards by the clamping jaw 5 to be separated from the supporting structure at the bottom, the blank material is dragged on the reaming core rod 1 by the clamping tool, and after the blank material reaches the second column 12, the manipulator 4 is controlled to lower the reaming core rod 1 to stably fall on the supporting structure.

The first column 10 and the second column 12 are respectively supported by the first horse frame 2 and the second horse frame 3;

further, the first horse frame 2 and the second horse frame 3 have the same structure, the first horse frame 2 comprises a support body 21, an upper support plate 22 and a lower support plate 23 which are parallel up and down are arranged below the support body 21, and the upper support plate 22 and the lower support plate 23 are fixed through a support bolt 24;

specifically, this utility model in practical application, not confine to certain fixed specification, can carry out the adjustment of numerical value in order to adapt to specific production requirement according to actual need, therefore first horse 2 and second horse 3 should be applicable to different heights, only need reciprocate support bolt 24 between upper support plate 22 and bottom suspension fagging 23, can realize the adjustment of first horse 2 and second horse 3 height, use more in a flexible way.

The working principle is as follows:

in the specific trestle reaming procedure, the reaming core rod 1 is lifted upwards by controlling the operating machine 4, then the blank material is placed on the first column 10, then the blank material is rotated and pressed by a pressing wheel structure which is supported by a moving frame from the upper part, so that the radius of an inner hole of the blank material is continuously enlarged, the blank material reaches the reaming radius at the stage, then the blank material passes through a transition body 11 and reaches a second cylinder 12, and then the blank material is uniformly rotated and pressed by the pressing wheel structure which moves along with the transition body to enlarge the inner diameter of the blank material, the movable frame can make the pinch roller structure move horizontally and vertically on the movable frame to finally reach the preset hole-expanding size of the trestle, in the process of reaming the trestle by using the utility model, the single reduction is large, so that the center of the blank material is completely forged by the reaming core rod 1, therefore, the structure performance of the ring forging is improved, the number of fire times for special alloy can be reduced, and the risk of cracking is reduced.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
